Background of the Invention

Field of the Invention This invention relates to spinning-type fishing reels of the type having a trip mechanism for automatically changing the fishing reel from its cast mode into its re¬ trieve mode upon the completion of a cast and, more partic¬ ularly, to a mechanism for preventing jamming of the trip mechanism as the fishing reel is placed in the cast mode.

Background Art

Spinning-type fishing reels are well known in the prior art. Typically, a spinning reel has a frame defining a mounting foot for attachment to a rod. A rotor is ount- ed to the frame for rotation about a fore and aft axis. A

line-carrying spool is coaxial with the rotor axis and oscillated in a fore and aft direction by operation of a crank handle, which crank handle operation simultaneously rotates the rotor to thereby evenly wrap line on the line- carrying spool.

To effect a cast with a basic spinning reel, the user picks up the line projecting away from the reel, with a finger on the same hand that holds the rod, and snubs the line against the rod. With the other hand, the user anu- ally pivots the bail assembly from a retrieve position to a cast position. The rod is then cocked and thrust in the direction of the cast. As the rod is thrust, the user moves the line snubbing finger to release the line. Once the cast is completed, the user operates the crank handle to rotate the rotor. A trip mechanism on the moving rotor is automatically actuated by a cam element on the reel frame to force the bail assembly from the cast position back into the retrieve position.

Typically, the trip mechanism has a camming shoulder on the reel frame to intercept a trip link. The trip link is projected rearwardly from the rotor as the reel is placed in the cast mode. The projecting trip link rides up the cam shoulder, forcing the bail assembly to¬ wards the retrieve position, until an overcenter mechanism drives the bail assembly into its retrieve position.

One difficulty with the above structure is that there is a "dead spot" with the trip link aligned over the camming shoulder. This "dead spot" is commonly existent through approximately 15 ^* of rotation for the rotor. If the bail assembly is urged from its retrieve position towards its cast position with the trip link aligned over a high point on the cam shoulder, the bail assembly will jam. Forcing of the bail assembly may result in breakage of reel parts.

While this problem is not too severe with a fully manual bail, it poses a more serious problem with a trigger actuated bail assembly. In the case of a manual bail sys¬ tem, the user is already grasping the bail. A slight shift of the rotor can alleviate the problem. However, with trigger operated systems, the user ideally does not have to directly manipulate the bail. If the "dead spot" is en¬ countered, the user will normally either press harder on the trigger, which may damage the reel, or reach under the rod and shift the rotor.

Exemplary prior art trigger mechanisms, in which the problem of "dead spots" must be contended with, are shown in each of U.S. Patent Nos. 2,658,697, to Steinbaugh, 3,095,158, to Louison, 3,796,391, to McMickle, and 3,908,927, to Louison.

Summary of the Invention

The present invention is specifically directed to overcoming the above enumerated problems and improving the presently known bail operating mechanisms. According to the invention, a fishing reel is provided having a frame, a rotor mounted to the frame for rotation about a first axis, a line storage spool, a struc¬ ture for rotating the spool, a bail assembly on the rotor having first and second bail arms mounted to the rotor for pivoting movement between a first position wherein the bail assembly is in (a) a retrieve position so that the bail directs line onto the line storage spool as the rotor is rotated and (b) a second position wherein the bail assembly is in a cast position, a trip link mounted to the rotor for movement relative to the rotor between third and fourth positions, cooperating structure on the bail assembly and trip link for moving the trip link from its third position into its fourth position as an incident of the bail assem-

bly moving from its first position into its second posi¬ tion, and a trip link actuator on the reel frame and defin¬ ing a shoulder that intercepts the trip link with the trip link in its fourth position and the rotor rotating in a first rotational direction about its axis and moves the trip link from its fourth position towards its third posi¬ tion. The cooperating structure on the bail assembly and trip link includes a structure for moving the bail assembly from its cast position towards its retrieve position as an incident of the trip link moving from its fourth position into its third position. The trip link structure allows repositioning of the trip link relative to the rotor in the event that the trip link encounters the trip link actuator as the trip link moves from its third position towards its fourth position to thereby prevent jamming of the trip link by the trip link actuator and allow the trip link to move fully into its fourth position.

With the inventive structure, "dead spots" can be eliminated so that the bail assembly can be moved between its first position and second position regardless of the rotational orientation of the bail assembly. A full 360' actuation range for the bail assembly is thus made possi¬ ble.

In one form of the invention, the trigger is mounted to the reel frame for pivoting movement between a rest position and an operating position and there is struc¬ ture cooperating between the trigger and bail assembly for moving the bail assembly from its retrieve position into its cast position as an incident of the trigger moving from its rest position into its operating position and the shoulder on the trip link actuator is on the trigger.

In one form, the trip link mounting structure mounts the trip link for movement in a substantially linear path between its third and fourth positions.

The rotor has an elongate guide surface and the trip link has a guide edge for engaging and moving guid- ingly along the rotor guide surface as the trip link moves between its third and fourth positions. In one form, biasing structure is provided for normally biasing the trip link so that the trip link guide edge is against the rotor guide surface. A preferred form of the biasing structure is a coil spring.

In one form, the trip link has an elongate con- figuration with spaced free ends, with one of the free ends directly engaging the bail assembly and being driven by the bail assembly as the bail assembly moves from its retrieve position into its cast position to move the trip link from its third position towards its fourth position. The other free trip link end defines the cam edge, which, in one form, has a convex configuration.

In one form, the trip link actuator has a ramped surface for encountering the cam edge and progressively deflecting the trip link against the force exerting by the biasing structure as the trip links moves from its third position towards its fourth position.

In one form of the invention, there is a trigger mounted to one of the reel frame and rotor for pivoting movement between a rest position and an operating position. There is structure cooperating between the trigger and bail assembly for moving the bail assembly from its retrieve position into its cast position as an incident of the trig¬ ger moving from its rest position into its operating posi¬ tion. The structure cooperating between the trigger and bail assembly includes a force transmission arm that is pivotably mounted to the rotor for movement between fifth and sixth positions. There is structure cooperating be¬ tween the trigger and force transmission arm for moving the force transmission arm from its fifth position into its

sixth position as the trigger is moved from its rest posi¬ tion into its operating position and further cooperating structures provided on the force transmission arm and bail assembly for moving the bail assembly from its retrieve position into its cast position as an incident of the force transmission arm moving from its fifth position into its sixth position. The force transmission arm and rotor cap- tively hold the trip link in an operative position on a fishing reel. Accordingly, the force transmission arm can be made to be a multi-functional element.

The invention also contemplates the trip link mounting structure mounting the trip link for movement in other than a straight line in a predetermined path between its third and fourth positions.

Further according to the present invention, a fishing reel rotor assembly is provided for directing line onto a line carrying spool. The rotor assembly has a ro¬ tor, a bail assembly mounted to the rotor for pivotable movement between a first retrieve position and a second cast position, a trip link mounted to the rotor for move¬ ment relative to the rotor in a predetermined path between third and fourth positions, and structure cooperating be¬ tween the bail assembly and trip link for causing the bail assembly to move the trip link from its third position into its fourth position as an incident of the bail assembly moving from its first position into its second position and for causing the bail assembly to move from its second posi¬ tion into its first position as the trip link is moved from its fourth position into its third position.

In one form, the trip link has an edge that is engageable by an actuator to drive the trip link from its fourth position into its third position. The trip link mounting structure includes a structure for allowing at

least a portion of the trip link to be deflected out of the predetermined path to prevent jamming of the trip link as the trip link moves from its third position towards it fourth position. In one form, the trip link has an enlargement defining a shoulder against which the biasing structure, which may be a coil spring, can act.

In one form, the trip link has another enlarge¬ ment defining a shoulder that abuts the rotor to limit pivoting of the trip link as it is deflected out of its predetermined path.

Detailed Description of the Drawings

In Figs. 1-13, a spinning-type fishing reel is shown at 10 having incorporated therein a preferred form of bail operating mechanism according to the present inven- tion. Before the details of the invention are described, the overall reel operation will be briefly described to set the environment for the present invention.

The spinning reel 10 has a frame 12 with a hous¬ ing 14 that contains the internal operating mechanism for the reel 10. A detailed description of the reel operating mechanism is unnecessary to understand the present inven¬ tion. A detailed description of the operating mechanism is given in U.S. Patent No. 4,676,450, which is incorporated herein by reference. The frame housing 14 extends upwardly to define a mounting stem 16, which terminates in a mounting foot 18 that can be attached to a fishing rod (not shown) in con¬ ventional fashion.

The frame 12 carries a rotor 20 at its forward end. The rotor 20 is mounted to the frame 12 for rotation about a fore and aft axis 22. Rotation is imparted to the rotor 20 by a crank handle 24. Rotation of the crank han¬ dle 24 about a laterally extending axis 26, in the direc¬ tion of arrow 28, through an internal operating mechanism, shown schematically at 30 in Fig. 1, effects rotation of the rotor 20 about the axis 22 in the direction of arrow 32, i.e. in a clockwise direction as viewed from the front of the reel 10.

The rotor 20 is configured to direct line onto a line carrying spool 34 in a wrapping motion. An internal oscillating mechanism 36, also operated by the crank handle 24, moves the spool 34 in a reciprocating fore and aft path, as indicated by the double-headed arrow 38, so that

line 40 is distributed evenly along the length of the line carrying spool 34.

Line 40 is wrapped around the spool 34 by a bail assembly at 42. The bail assembly 42 is attached to the rotor 20 and, more particularly, to mounting ears 44,46 at diametrically opposite locations on the rotor 20. The mounting ears 44,46 have laterally outwardly extending mounting posts 48,50 which project into through bores 52,54 on bail arms 56,58, respectively, to thereby support the bail arms 56,58 for pivoting movement about a common axis 60. A U-shaped bail wire 62 has its ends connected to the bail arms 56,58 so that the bail arms 56,58 and bail wire 62 rotate as a unit between the retrieve position, shown in solid lines in Fig. 1, and the cast position, shown in phantom lines in that same figure. An overcenter bias structure, shown schematically at 63 in Figs. 1 and 3, drives the bail assembly into each of the cast and retrieve positions as the bail assembly approaches each. Suitable overcenter bias structures are well known to those skilled in the art.

The bail arm 56 has a line receptacle 64 defined cooperatively by a wall 66 on the bail arm 56 and a line roller 68. The receptacle 64 is generally U-shaped and opens in the direction of advancement of the rotor 20 dur- ing line retrieval.

The line 40 normally projects from the spool 34 through an opening 70 defined at the juncture of the wall 66 and line roller 68. The line roller 68 guides line 40 that is paying out as the spool 34 rotates with the rotor 20 stationary, as when a fish overcomes the normal drag force exerted on the spool 34. As the rotor 20 is rotated in the direction of arrow 32, to retrieve the line 40, the line 40 slides down the line roller 68 and into the recep-

tacle 64, whereupon the wall 64 and/or line roller 68 draw the line 40 around the oscillating spool 34.

By pivoting the bail assembly 42 in the direction of arrow 72 in Figs. 1 and 2, the bail assembly 42 is placed in the cast position. In the cast position, the line 40 is allowed to freely pay off of the spool 34. Once the desired amount of line 40 is paid out, the crank handle 24 is operated to automatically reposition the bail assem¬ bly 42 in the retrieve position through a mechanism accord- ing to the invention, that will be described in detail below.

More particularly, the present invention is di¬ rected to a mechanism for placing the bail assembly 42 into the cast position from the retrieve position therefor and for causing the bail assembly 42 to automatically move back into the retrieve position upon the completion of the cast.

The present invention employs a bail assembly actuator in the form of a trigger 74. The trigger 74 has an overall "L" shape with an elongate forwardly projecting finger engaging portion 76 and a transverse bail actuating portion 78. The bail actuating portion 78 terminates in a U-shaped yoke 80 with spaced legs 82,84. The trigger 74 is mounted to the frame 12 by a pin 86 for pivoting movement about a laterally extending axis between a rest position, shown in Figs. 1 and 6, and an operating position, shown in Fig. 5. The trigger 74 is spring loaded towards its rest position.

Drawing up on the finger actuating portion 76 of the trigger 74, and moving the trigger 74 from its rest position to its operating position, advances the legs 82,84 forwardly into engagement with an annular, actuation plate 88. The actuation plate 88 operates within an internal space 90 defined by an annular wall 92 on the body 94 of the rotor 20. A mounting wall 96 serves as a support for

the actuation plate 88 and guides movement of the actuating plate in a fore and aft direction. The actuation plate 88 is connected to four guide posts 98,100,102,104, which are spaced equidistantly around the circumference of the actua- tion plate 88. The preferred means for interconnecting the guide posts 98,100,102,104 and actuation plate 88 is de¬ scribed below. The guide posts 98,100,102,104 are of equal length, elongate and project substantially parallel to each other in a fore and aft direction, i.e. parallel to the center axis of the actuation plate 88.

To stabilize the posts 98,100,102,104, an annular reinforcement plate 106, having a configuration similar to the plate 88, is mounted to the free ends of the posts 98,100,102,104. The plates 88,106 and posts 98,100,102,104 together define a unitary plate assembly.

Prior to assembly of the reinforcement plate 106, the posts 98,100,102,104 are directed through bores 108, 110,112,114, consecutively, from the rearwardly facing side 116 of the wall 96, until the posts 98,100,102, 104 project beyond the front, forwardly facing surface of the wall 96. Once the reinforcement plate 106 is attached to the posts 98,100,102,104, as by screws 120, the wall 96 is held cap¬ tive between the actuating and reinforcement plates 88,106. In one form, the posts 98,100,102,104 have a circular cross section taken transversely to their length. The bores 108,110,112,114 have a corresponding cross sec¬ tion to accept and guide the posts 98,100,102,104 in a fore and aft direction. This described guide arrangement as¬ sures that the movement of the entire plate assembly is consistently linear in a fore and aft line. The trigger legs 82,84 act on the rearwardly facing surface 122 of the plate 88 at diametrically opposite locations thereon to distribute the bail operating force from the trigger sub-

stantially uniformly across the plate 88 and avoid canting of the plate assembly.

The actuation plate 88 is normally biased in a rearward direction. This is accomplished by providing springs 124 (one shown) around each of the posts 98,100, 102,104 so that the springs 124 act between the rearwardly facing surface 116 of the wall 96 and the actuation plate 88.

As the actuation plate 88 is translated forwardly from a retracted position into an extended position by the trigger 74, the actuation plate 88 acts against and simul¬ taneously pivots the force transmission arms 128,130 to cause the force transmission arms 128,130 to drive their associated bail arms 56,58 into their cast position. The actuator arm 128 consists of first and second joinable parts 132,134. The transmission arm part 132 is situated externally of the reel whereas the transmission arm part 134 is located primarily within the rotor space 90. The arm part 134 has a cylindrical shaft 136 that projects fully through a bore 138 in the rotor wall 92 to be exposed externally of the rotor body 94. The exposed portion 140 of the arm part 134 has flats 142,144 to make keyed connection with a correspondingly configured bore in the arm part 132. A screw 146 maintains the coupled ar- rangement of the arm parts 132,134 through the rotor wall 92.

The arm part 134 has an elongate, curved exten¬ sion 148 projecting transversely to the length of the shaft 136. The free end 150 of the extension 148 has a curved cam edge 152 which abuts to the forwardly facing surface 154 on the actuation plate 88. As the actuation plate moves from its retracted position into its extended posi¬ tion, the actuation plate 88 effects rotation of the exten-

sion 148, and the arm part 132 keyed thereto, in the direc¬ tion of arrow 156 about the axis 158 of the shaft 136.

As the extension 134 is pivoted by the actuation plate 88, a shoulder 160 on the arm part 132 is brought to bear against a kidney-shaped pin/projection 162, which is offset radially outwardly and forwardly from the pivot axis 60 for the bail arm 56. Pivoting of the arm part 132 ex¬ erts a force on the bail assembly 42 to pivot the same in the direction of arrow 72 towards a cast position. A coil spring 166 acts between the wall 96 and free end 150 of the extension 148 to normally bias the force transmission arm 128 oppositely to the direction of arrow 156. Bosses 168,170 are provided on the wall 96 and extension 134 respectively to penetrate and maintain the coil spring 166 in position.

The force transmission arm 130 has a similar two- part construction including an arm part 172 within the rotor space 90 and having a keyed projection 174 to mate with an arm part 176 externally of the rotor. A screw 178 maintains the keyed connection of the arm parts 172,176.

The arm part 172 has an extension 180 that is acted upon by the actuation plate 88 to effect rotation of the arm part 176 about the axis 182 of the projection 174 on the arm part 172. A similar spring biasing structure (not shown) biases the extension 180 normally into contact with the actuation plate 88.

Forward movement of the actuation plate 80 pivots the arm 130 about the axis 182 in the direction of arrow 184. A shoulder 186 engages a pin 188. With the bail arm 58 in the solid line, retrieve position shown in Fig. 7, the pin 188 resides axially rearwardly of the bail assembly pivot axis 60. Pivoting of the arm 130 in the direction of arrow 184 effects a counterpivoting of the bail arm 58 in the direction of arrow 190.

The arms 130,132 pivot oppositely to each other about their respective axes 182,158. The axes 158,182 are parallel to but slightly offset from each other.

A further aspect of the invention is to configure the pins 162,188 and shoulders 160,186 so that there is a slight lag in operation of the pin 162 and shoulder 160 upon the trigger 74 being actuated. The pin 188 and shoul¬ der 186 are relatively situated with the reel in a retrieve mode so that upon the actuating plate 88 moving forwardly, the shoulder 186 is abutted to the pin 188 and optimally oriented to develop a large torque on the bail arm 58. This large force that is produced as the bail assembly 42 is moved from a stationary position is often compromised in conventional structures to add to the pivot range. Once the bail arm 58 pivots in the direction of arrow 190 a predetermined amount, the shoulder 160 confronts the pin 162. The pin 162 and shoulder 160 are configured to allow the arm 128 to positively drive the bail arm 56 fully into the retrieve position of Fig. 2. In the absence of this arrangement, the shoulders 160,186 and pins 162,188 would have to be configured to all simultaneously coact, in which event the pivoting range for the bail assembly 42 would be limited to the range permitted by each pin and shoulder. Normally this range is on the order of 120 ^* and difficult to achieve effectively with the conventional construction, given the normal space constraints and manufacturing toler¬ ances. As noted above, this conventional construction compromises the initial force that moves the bail assembly 42 from the stationary retrieve position. With the stag- gered arrangement, the pivot range can be extended without sacrificing the necessary starting force.

This feature is particularly desirable with reels incorporating a line holding pin 192. The pin 192 projects in cantilever fashion from an L-shaped support arm 194

pivotably mounted to the free end 196 of the arm 128 for rotation about an.axis 198 defined by a mounting pin 200. As the arm 128 drives the bail arm 56 into the cast posi¬ tion, the pin free end 202 abuts the edge 204 of the bail wire 62 to thereby block the line in the receptacle 64. Reserve travel for the bail assembly is built into the pin 162 and shoulder 160 arrangement to allow positive clamping of the pin free end 202 to the bail wire edge 204 so that the forces during casting do not overcome the clamping force of the line holding pin 192 that might cause prema¬ ture line release.

With the inventive structure, pulling up on the trigger 74 moves the bail assembly 42 from the retrieve position into the cast position therefor. At the same time, the pin 192 blocks the line in the line receptacle 64, thereby obviating the need to snub the line 40 against a rod as the rod and reel are cocked in preparation for a cast. To complete the cast, the rod and reel 10 are thrust forwardly and simultaneously the trigger 74 is released. Upon release of the trigger 74, the arm 128 pivots under the force of the spring 166 to back the pin 192 off of the bail wire 62 to allow the line 40 to pay freely off of the spool 34.

Another significant aspect of the present inven- tion is that the bail assembly 42 is movable through the trigger 74 from the retrieve position into the cast posi¬ tion regardless of the rotational position of the bail assembly 42. Thus, no self-centering mechanism is neces¬ sary, as is common on prior art reels which have a rotor that is operable in only a very small range of positions. The user need not concern him or herself with the position of the bail assembly 42 with the inventive structure.

Another aspect of the present invention is a novel mechanism at 206 to prevent jamming of the bail as-

sembly 42 as it moves from the retrieve position to the cast position and for returning the bail assembly 42 from the cast position to the retrieve position upon rotation of the crank handle 24 at the completion of a cast. A trip link 210 cooperates with the bail arm 58 and is movable thereby from the solid line retracted posi¬ tion in Figs. 7 and 8 to the extended phantom line posi¬ tions, as the baϋ assembly moves from its retrieve posi¬ tion into its cast position. The trip link 210 has a substantially straight edge 212 which engages and is guided along a straight guide surface 214 defined by the rotor 20. Preferably, the edge 212 and surface 214 are straight so that the trip link 210 moves linearly between the solid line position and the phantom line position. It is not necessary, however, that the predetermined path followed by the trip link 210 be linear.

The bail arm 58 has an inwardly projecting pin 216 that engages and drives one trip link end 218 as the bail assembly 42 rotates in the direction of arrow 220 in Figs. 7 and 8. Upon the bail assembly 42 being placed in the cast position, the opposite free end 222 of the trip link 210 projects to the phantom position A, shown in Fig. 8. Once the cast is completed, the user rotates the crank handle 24, which bears the extended trip link end 222 against a shoulder/ramp surface 224 on a trip link actuator 226 mounted on the trigger 74, as shown in Fig. 1.

The present invention comprehends a mechanism for allowing at least a portion of the trip link 210 to be deflected out of its predetermined path so that the trip link will not jam with the actuator 226. In the absence of this mechanism, there is a "dead spot" where the bail as¬ sembly 42 cannot be automatically actuated. More specifi¬ cally, if the trip link free end 222 is aligned over the

apex 228 of the actuator 226 as the trigger 74 is actuated, the end 222 encounters the apex 228, as seen in phantom position B in Fig. 8, so that the movement of the trip link 210 is arrested which thereby blocks movement of the bail assembly 42 fully into the cast position.

According to the invention, the trip link 210 is mounted to the rotor 20 to be repositionable, and prefera¬ bly pivotable, about its free end 218 to the phantom line position C. A coil spring 232 normally biases the trip link 210 forwardly and in a clockwise direction in Fig. 8 so that the guide edge 212 and guide surface 214 are held in abutting relationship. The trip link 210 has an en¬ largement 234 defining a shoulder 236. The spring 232 acts between a shoulder 238 on the rotor 20 and the shoulder 236 in biasing the trip link 210 to the solid line position of Fig. 8.

According to the invention, the free end 222 of the trip link 210 has a convex cam edge 240 which, upon encountering the apex 228 of the trip link actuator 226, deflects the free end 222 of the trip link 210 to the right in Figs. 7 and 8 against the bias of spring 232 under the force of the pin 216 acting on the trip link end 218. The cam edge 240 is guided down the ramp surface 224 suffi¬ ciently to allow the full extension of the trip link 210 to phantom position C as the bail assembly 42 moves into the cast position. The angle and circumferential extent of the ramp surface are selected to complement the angle that the trip link 210 must pivot through to allow the full requi¬ site projection of the trip link 210. A second enlargement 242 can be provided on the trip link 210 to define a shoulder 244 to abut a shoulder 246 on the rotor 20 to limit pivoting of the trip link 210 in a counterclockwise direction in Figs. 7 and 8. Also, a shoulder 248 bounding a cutout in the rotor 20 abuts the

trip link edge 250 to similarly limit pivoting movement of the trip link 210.

By operating the crank handle 24, the cam edge 240 on the trip link 210 encounters the ramp surface 224 to progressively urge the trip link 210 forwardly to thereby bear the trip link end 218 against the pin 216 to pivot the arm 58 sufficiently to allow the overcenter bias structure 63 to resituate the bail assembly 42 in the retrieve posi¬ tion. The force transmission arm 130 is assembled in overlying relationship to the trip link 210. Consequently, the trip link 210 can be held captively in its operative position between the rotor 20 and the transmission arm 130. The rotor 20 and/or transmission arm 130 guide movement of the trip link between its extended and retracted positions.

A preferred configuration for the actuation plate assembly is shown in Figs. 14-18. In Fig. 14, a one-piece construction for a plate assembly is shown at 252. The plate assembly consists of a single piece of sheet metal 254 that is stamped to provide a center cutout 254 and integral posts 256,258,260,262, spaced equidistantly around the circumference of the annular center plate 264. After the stamping operation, each post 256,258,260,262 is bent through approximately 90 ^* to project at right angles to the planar surface 266 of the plate 264.

Fig. 15 shows a preferred means of connection between the actuation plate 88, one of the guide posts 98 and the reinforcement plate 106. The rear end 268 of the post 98 has a tapered portion 270 with a diameter that increases progressively from front to rear. The rear edge 272 of the post 98 has a diameter slightly larger than the diameter of a bore 274 in the plate 88 for reception of the post end 268. By press fitting the tapered portion 270 into the bore 274, the rear edge 272 deforms slightly and

springs back with the post 98 fully seated in the plate bore 274 to effect a secure hold. A screw 120 is secured in a threaded bore 276 in the forward end 278 of the post 98. Figs. 16-19 show alternative shapes for the posts

98,100,102,104. The post 98' in Fig. 16 has a rectangular cross-sectional configuration. The post 98" in Fig. 17 has a triangular cross-sectional configuration. The post 98'" in Fig. 18 has a cylindrical center portion 280 and three arcuate lobes 282,284,286 spaced equidistantly around the center portion 280. In Fig. 19 a post 98"" is shown and has a diamond-shaped cross-sectional configuration. The guide bores 108,110,112,114 for the posts 98,98' ,98",98'", 98"" have a matched cross section. However a non-matched cross section is often preferred. For example, if a trian¬ gular cross section is used in a round bore, there is con¬ tact by the post at only three points, however the guiding function is fully realized. Friction forces are thereby reduced. The posts 98,98' ,98",98'",98"",100,102,104 can be made by any of a number of well known techniques, as by extrusion, molding, casting, etc. In place of the screws 120 and the tapered portion 270 that allows press fit con¬ nection, the plate assembly parts can be welded, bolted, riveted, or otherwise suitably interconnected.

For aesthetic purposes, covers (not shown) can be placed over the bail arms 56,58 and secured to the bail ears 44,46.

The foregoing disclosure of specific embodiments is intended to be illustrative of the broad concepts com¬ prehended by the invention.
