Abstract
459,109. Holding tools. BEDFORD, R. A., Grange Farm, Stumperlowe, Sheffield. July 1, 1936, No. 18281. [Class 61 (ii)] A device for holding drill bits during forging, hardening, &c. of the kind described in Specification 439,440 comprising a tubular shank a with tapered spigot b to engage the tapered socket c of the drill bit d, a collar k near the tapered spigot with resilient fingers m for gripping the outside of the drill bit and a rod e slidable within the shank for dislodging the drill bit from the tapered spigot by hammering on the end of the rod is provided with a detachable hammering part or anvil g on the end of the rod screwed thereon and secured by a cross pin j, the anvil having a hollow extension h slidably guided on the end i of the tubular shank to prevent distortion of the rod when hammering on its end. Passages n, o, p are provided for the escape of fumes when the device is used for hardening drill bits by plunging them in quenching liquid.
