Abstract

747,902. Hand saws. DERRICK, Ltd. J., and THOMSON, J. L. June 30, 1954 [July 1, 1953] No. 18241/53 Class 61 Relates to hand saws of the kind in which the back edge of the blade 10 is carried by a support 11 which slides backwards in a handle 13 against spring action during forward movement of the blade. According to the invention the support moves against the action of two springs 26 located one on each side of the support each spring being connected as at 27 to the handle and at its other end to the support. The handle shown is composed of half-members 14 meeting on a central vertical plane and so shaped as to provide channels 25 for the springs 26, guide surfaces for the support 11, and a rebate for the blade 10. The latter has a hole for receiving the plain end of a locating screw 19. The support 11 has a slot which engages a guide lug 28 in the handle and carries a yoke 20 which has arms over which the springs are hooked, the front face of a part 22 of the yoke abuts the base of a recess of a boss 17 in the handle when the support is in its forward position. The support is fitted with a work-engaging foot at its front end.
