ABSTRACT:
A guard for moving-blade cutting instruments, for instance band-saws and band-knives. The guard is in the form of a comb or other toothed member, mounted alongside the blade and vibrated cyclically so that the tips of the teeth lie proud of the cutting edge at least once per cycle. The clearances between the teeth are aligned so as to facilitate access of piles of cloth or the like to the blade, but the bulkier fingers of the operator should be struck by the tips of the vibrating comb and repelled before being seriously cut, or cut at all, by the blade. The guard may be mounted to yield within limits, so as to increase the exposure of the blade, when subjected to sustained pressure from approaching work.
