Manufactured by Racine Tool & Machine Co. - Racine, Racine County WI
Assigned to Racine Tool & Machine Co. - Racine, Racine County WI

Abstract: In power driven hack saws as heretofore constructed, difficulty has been encountered due to the dropping of the saw and frame after the completion of the cutting operation, frequently breaking the saw and occasionally injuring the operator. A further difficulty has been experienced in removing the finished work and positioning new work in the machine. The operator usually has to hold or jack up the saw, to maintain it in elevated position while the old work is being removed and the new work inserted. Claim: A power driven hack saw comprising a saw frame, means for reciprocating said frame, a pivotally mounted guide for said frame, means for lifting said frame upon the idle stroke, means for releasing said lifting means at the beginning of the working stroke, and other means including a pawl and ratchet for operatively supporting said frame when said lifting means is released to limit the downward motion of said frame during each working stroke.
