Abstract

569,428. Percussive drills. RIPBITS, Ltd. (Griffiths, H. M.). Aug. 17, 1943, No. 13367. Drawings to Specification. [Class 124] In a percussive drill comprising a drill bit provided with a taper socket of less depth than diameter to receive a taper plug on the end of a drill rod, as described in Specification 519,818, the plug has a greater degree of taper than the socket and is an oversize fit therefor throughout its engagement therewith so as to effect an expansion of the socket such that at-the orifice thereof said expansion will be greater than the expansion at the area of the socket immediately around the extremity of the plug. Suitable dimensions are given in the Specification.
