Abstract

592,129. Nail punches. VOIZOT, R. May 17, 1945, No. 12399. Convention date, March 22, 1943. [Class 89 (iii)] [Also in Group XXII] A nail or other punch of the type comprising a thin rod provided with a percussive head, has means for adjusting the position of an external sleeve with respect to the rod during working. The rod a extends from a screw-threaded portion b which forms part of the percussive head c. A sleeve d fits over the rod a and has at its end a close-fitting bore e to form a bearing or guide for the rod. The upper part of the sleeve d fits on the percussion head c, and is provided with an internally threaded portion g which co-acts with the screw-thread b. The distance which the rod a projects from the sleeve may thus be adjusted. In a modification, the screw-threaded portion is replaced by a helical groove, or a tapping may be made in the head c and the sleeve threaded to enter it. In a further modification, the rod slides freely in the sleeve against a spring, or friction means, such as a braided metal sheath, or a rubber washer may be provided to brake the relative sliding. The tool may be made sufficiently strong to be used as a punch for perforating sheet metals or other materials.
