Abstract
Abstract A sabor saw device for attachment to a standard drill motor converts the rotary motion of the drill motor to reciprocating motion of a saw blade. The blade is locked to the reciprocable mechanism in a manner to prevent inadvertent disengagement of the blade while the saw is in operation. The blade and reciprocable mechanism are compatibly designed so that either a single ended or double ended blade may be mounted on the driving mechanism.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
208 words
A saber saw blade for a drive mechanism having a reciprocal platen provided with a fixed lug and a spring biased pin spaced from the lug and offset relative thereto in one direction of reciprocation of the platen, said blade comprising: an elongated metallic strip having a body portion adapted to be coupled with the platen and a working portion integral with the body portion and extending away therefrom, said body portion having a pair of opposed side edges and an aperture therethrough, the aperture being disposed generally midway between the side edges of the body portion, said working portion having a side margin coextensive with a first of the side edges of the body portion, there being a series of sawteeth along said side margin of the working portion, and a lug-receiving notch formed in the second of the side edges of the body portion and being offset relative to the aperture in the opposite direction of reciprocation of the platen, said first side edge of the body portion having continuous stretches on opposite sides of the notch, said blade being removably positionable adjacent to the platen with the lug of the platen received in the notch and the pin of the platen received in the aperture.

A saber saw blade for a drive mechanism having a reciprocal platen provided with a fixed lug and a spring biased pin spaced from the lug and offset relative thereto in one direction of reciprocation of the platen, said blade comprising: an elongated metallic strip having a body portion adapted to be coupled with the platen and a working portion integral with the body portion and extending away therefrom, said body portion having a pair of opposed side edges and an aperture therethrough, the aperture being disposed generally midway between the side edges of the body portion, said working portion having a side margin coextensive with a first of the side edges of the body portion, there being a series of sawteeth along said side margin of the working portion, and a lug-receiving notch formed in the second of the side edges of the body portion and being offset relative to the aperture in the opposite direction of reciprocation of the platen, said first side edge of the body portion having continuous stretches on opposite sides of the notch, said blade being removably positionable adjacent to the platen with the lug of the platen received in the notch and the pin of the platen received in the aperture.
Claim 3
Dependent Claim
88 words
A saber saw blade as set forth in claim 1, wherein a pair of working portions are provided on said strip, the body portion being disposed between the working portions so that they extend therefrom in opposite directions, there being a second lug-receiving notch formed in the body portion in the first side edge thereof and offset axially therealong on the opposite side of the aperture so that both notches and said aperture lie along a line angularly disposed with respect to the longitudinal axis of the strip.
