Abstract: The present invention is an improved key for an in-line transmission. The key is located within a channel in the shift shaft and selectively engages keyways of gears disposed about the shift shaft. A shift fork and collar axially move the key within the shift shaft by engaging and moving the base of the key. The key includes a shoulder which connects the head and the shank portion of the key, with the shoulder being thicker than the shank to cause more of the key to be supported within the shift shaft channel and thereby the key is better able to withstand the shearing forces which result from the rotational coupling of the shift shaft and the gears. The shoulder includes the portion of the key which extends out of the channel to the keyway and connects with the head, and which also faces the same direction as the head.

Abstract: The invention pertains to a saw, in particular to a jig saw or scroll saw, with a saw blade which is driven by a force acting on a parallelogram of rods. A saw blade is attached to a connecting shank which joins two longitudinal side arms. The two longitudinal side arms are designed to move in their longitudinal direction. On at least one of the two longitudinal side arms a guide element in the form of, for example, a turning roller, is positively guided against a stationary guide surface which is at an angle, preferablye an acute angle, to the connecting shank. As a result of this positive guidance, the backward movement of the saw blade from the cut edge during the return stroke is reduced to a desired value. Thus a jig saw of small size, but with a large stroke, can be realized in which the saw blade is guided parallel to the cut edge at all times but is moved back by a small amount from the cut edge during the return stroke.

Abstract: An improved ball screw assembly is disclosed in which a return tube has a pair of minor legs which enter into two ends of the internal helical groove within a nut to return ball bearings between the two ends. Apertures are formed within the nut such that the return tube can be mounted as a one-piece item by moving it perpendicular to the central axis of the screw into the two apertures. The apertures are formed by removing all material which would normally be radially outward of the minor legs, and would prevent mounting of the return tube by moving it perpendicular to the axis of the screw. Due to this improved arrangement between the return tube and the nut, a one-piece return tube can be utilized which contacts the end of the helical groove at an angle parallel to the helix angle and tangent to the helical groove at the ends.
