Abstract
1,213,167. Tool bit and chuck. HALIFAX TOOL CO. Ltd. 14 Aug., 1968 [16 Aug., 1867], No. 37751/67. Heading B4C. [Also in Divisions E2 and F2] Two members, one telescopically received within the other, are retained in their telescopic positions by a pin comprising a length of helically wound wire located in a bore provided by aperture and recess means in the two members. The pin has a diameter greater than that of the bore, and is introduced into the bore after the application of torque to a portion of the pin. As illustrated the members are a splined tool bit 5, and a chuck 6 shaped to slidably receive the tool bit shank. A tool for application of torque and subsequent insertion or withdrawal of the pin is provided with a stem having a slot 14 and a notch 16 adapted to engage an end piece 3 of the pin.
