Abstract

139,081. Willetts-Adshead, Ltd., and Wright, W. May 26, 1919. Reciprocating-saw machines.-A metal-sawing machine comprises a vertical or substantially vertical reciprocating saw i, the successive strokes of which are maintained parallel to each other, and the saw is maintained in continual engagement with the work during its movement in both directions. The saw-frame h is provided with an extension f which reciprocates in guideways in a slide g adapted to be moved along a guide e by means of a weight r to keep the saw in engagement with the work on the table a. A cross-head k is reciprocated on guide-rods j by a crank o, the saw frame being connected to the cross-head by a pin-and-slot connexion l, k<1>. A pawl u can be engaged with a notch v to hold the saw away from the work, and the forward movement of the saw can be limited by a screw-threaded stop x.
