Abstract:
Figure 2 shows a jigsaw in which pendulum motion is imparted on the blade (24) (see Figure 1) by a bell crank lever (28) mounting a support wheel (26). The lever (28) is actuated by pin (34) passing through adjustment shaft (36). The pin (34) is actuated by fork lever (42) journalled around circular cam surface (48) and pivoted on axis (44). Cam surface (48) is eccentrically mounted on gear shaft axis (10). Rotational adjustment of shaft (36), which alters the mechanical advantage of fork lever cam surface (52), is effected by pin (60) passing through shaft (36) and pivotally mounted in slide switch (70). Arrangement allows for compact design of saw.
