Abstract
1,235,085. Rock drills. KENNAMETAL Inc. 3 Feb., 1970 [14 Feb., 1969], No. 4990/70. Heading B3C. A rock drill comprises a chuck 12, Figs. 1 and 2, driven by a rotary air motor 10, a hollow drill string 14 connected to a tool 28, a suction conduit 22 connected to the driven end of the drill string, the latter having at least one port 38 at the tool end for removing the fines from the drilling region, through the string, which latter is formed of at least one hexagonal tubular member, a driver 24 having a shank 46 for connecting the string to chuck 12, and the tool 28 having a holder 26 whose shank 30 is located in the string, and friction elements 34, 50, carried by the shanks for frictionally retaining driver 24 and holder 26 in engagement with the string. Driving pressure is supplied to air motor 10 through a conduit 20. Elements 34, 50 may be split rings. Drill 28 is retained in holder 26 by a pin 44, and has a shank 42 for engagement in the square, or elliptical bore 40 of holder 26. Two or more drill strings 14 may be connected by a coupling member (56), Fig. 6 (not shown), which member has shanks (58) with split-rings (62). The driver 24 may be replaced by an adaptor with a hexagonal socket 62 having a split-ring 63, Fig. 7, which socket receives the drill string.
