This Patent of Invention refers to a " MECH NICAL CARRIER ", or more particularly, to a part transference - or transporta ion device, mechanical ly jointed, upon driving of pneumatic pistons, hand or automatical ly control by means of a control panel , in a way that the grasping system can be displaced pursuant to vertical and horizontal way, which are driven independently or jointly, so as to perm. t - the removal of a part from one place to another. Therefore, this mechanical carrier is presented as an automatic and/ or hand control led device, to used in mass or normal produc tion, in which various appl ications are feasible, mainly in metalworking shop, for extraction or automatic feed of " parts for the interior of metal stamped parts in any kind of pressing machines, as wel l as for transferences of parts from one machine to another, performing different operations. As last, this mechanical carrier can be used at any production site, either for mass * or normal production, wherein an - equipment to perform the moving of parts from one place to another, mainly between machines, is needed.
In order to provide a better understanding of this patent of invention, references wi l l be made to the attached drawings, wherein figure 1 is a front view; figure ■ 2 is a side view, under partial cut; finally figure 3 is a schematic side view, i lustrating the functioning of this mechanical carrier.
This Patent of Invention refers to a " MECHA¬ NICAL CARRIER " (see figures 1 and 2) comprising a chassis/ - base (1) , in vertical position, which provides the fastening of the set to the machine or equipment in which it shal l be used, said chassis presenting side guides (2) , wherein a movable internal body (3) , is moved, driven by a pneumatic cyl inder ( k ) , the body of which is fastened in paral lel to - the internal face of the chassis/base (1) ; in the upper part of the said movable body (3) is located a first jointed set-off set (5) comprising a pair of cross arms,

parallel to each other, one of them in upper position bj, and the other in a lower one (7), both with one of the ends jointly mounted to the movable body (3) , while the opposite ends of the same are also jointly fixed to a - triangular part (8) , the upper vertex has also fixed ther to the end of a chain (9) , which, in turn, is developed upwards, thus fitting a gear (10) mounted at the upper part of the movable body (3) » being afterwards developed downward, so as to have an end l inked to the piston of a . - set-off cylinder (11) , duly fixed to the movable body (3).
In one of the lower vertex of the triangular part (8) , or, more precisely, in its right angle vertex, there is jointly fixed, together with a corresponding end of the lower arm (7) , the upper end of a cyl indrical stem - (12) which develops downward and within a tubular jacket (13), the positioning of which is determined by an upper support (14) and another lower one (15), the upper support (14) having an end welded to the corresponding end of the jacket (13), while its other end is jointly fixed to - the free vertex of the triangular part (8), while the lower support (15) is geometrically fixed in a way that its free end can be jointly interconnected to the lower end of the stem (12) , through a horizontal element (16), and also to have the jointed ends of said supports (14) - and (15) remaining on the center l ine (A) paralel to the longitudinal center line (B) of the tubular jacket (13) , said paralel condition being maintained under any ci rcumstaπces .
A bearing (17) leaves the medium part of the - tubular jacket (13) , in the free end of which there is a cross axle (18), which is ortogonally centered on line (A) , so permitiπg that, at the free ends os said axle, the upper ends of the side arms (19) be jointly coupled, the lower ends being fixed to axles, revolvingly mounted at the - side parts (20) of the movable body (3) , wherein on of said axles is extended outward enough to receive a last radial arm (21) , at the free end of which it is coupled the terminal
of a piston 22 of a pneumatic piston 23 , conveniently mounted at the outer part of the movable chassis (3) .
According to the i 11 us rat ion ^of figure 3, any grasping accessory ( 2k ) can be coupled to the horizontal 1 - element (16) , the construction varieties occurϊng as a function of the part to be transported, including even vertical , horizontal , rotary and angular regulations.
The present "mechanical carrier " comprises several coupled sets, the function of which is to transform - the straight movements of pneumatic cyl inders ( k ) and (22) at the moment they are driven by means of a central control, comprising a control panel and a series of electrical and electronic components (not indicated in the drawings) , said movements, being already transformed, trans ited to the - carrying device ( 2 k ) , in such a way that it can be displaced by following a motion pre-programmed at said central control system, said motion being such that, among many others, it is just l ike the type schematically represented at the lower part of figure 3. - On the other hand, upward/downward vertical movements are effected by means of the pneumatic cyl inder ( k ) , internal ly placed, while the horizontal movements are effected by the pneumatic cyl inder (23) , logical ly together with the jointed parts of the set-off set (5) and the " jointed parts of the stem (12, 13 and 16) .
