Abstract
1462262 Hand saws ATLANTIC SERVICE CO Ltd 30 May 1974 [12 Oct 1973] 23978/74 Heading B5L In a back saw having a releasable blade and useable particularly for meat cutting or woodworking, a spine 13 having a V-groove 22 is provided fast with a handle (12), and a releasable blade 11 is secured to the spine by hooking the blade successively on to an arm 43 pivoted to the free end of the spine and on to a draw bar 25, tiltably guided in a slot 24 of a socket (15) fast with the spine, and then pulling the draw bar generally in the direction of the handle by means such as a threaded locking mechanism or, as shown, a cam 33 actuated by a removable tommy bar 40, the disposition of the parts of the saw being such that, preferably, the blade is thereby drawn up into the groove 22. By using a hardened metal cam 33, the saw components may be slightly stressed to maintain them in rigid twist-free interconnections. One or more shims 52 may interpose the cam and the socket (15). The single spine handle frame may be provided in combination with a variety of blades of different tooth sizes or configurations or materials. The saw blades may be flexible and may have a straight or sinuous back edge 53.
