Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
210 words
A hand tool for selectively supporting interchangeable working elements and comprising a main body member having a longitudinally extending bore provided in one end thereof for selectively receiving a working element therein, a transversely extending bore provided in the main body and in communication with the longitudinally extending bore, locking means pivotally secured to the main body member in the proximity of the bored end thereof and movable between locking and unlocking positions with respect to the transversely extending bore for removably securing the working element in a working position on the main body member, said locking means comprising a yoke member pivotally secured to the main body member and spanning the width thereof, a locking pin carried by the yoke member and engageable with the transverse bore in the locking position of the locking means for securing the working element in the working position, and wherein the yoke member comprises a substantially inverted U-shaped bracket having the opposite legs thereof loosely disposed on the opposite sides of the main body portion in the locking position of the locking means, and flange means extending outwardly from each leg of the U-shaped bracket and having elongated slot means therein for facilitating pivotally securing the yoke member to the main body member.
Claim 2
Dependent Claim
210 words
A hand tool for selectively supporting interchangeable working elements and comprising a main body member having a longitudinally extending bore provided in one end thereof for selectively receiving a working element therein, a transversely extending bore provided in the main body and in communication with the longitudinally extending bore, locking means pivotally secured to the main body member in the proximity of the bored end thereof and movable between locking and unlocking positions with respect to the transversely extending bore for removably securing the working element in a working position on the main body member, said locking means comprising a yoke member pivotally secured to the main body member and spanning the width thereof, a locking pin carried by the yoke member and engageable with the transverse bore in the locking position of the locking means for securing the working element in the working position, and wherein the yoke member comprises a substantially inverted U-shaped bracket having the opposite legs thereof loosely disposed on the opposite sides of the main body portion in the locking position of the locking means, and flange means extending outwardly from each leg of the U-shaped bracket and having elongated slot means therein for facilitating pivotally securing the yoke member to the main body member.
Claim 3
Dependent Claim
