Abstract

1460959 Drill extensions SANDVIK AB 19 Dec 1974 55001/74 Heading B4C [Also in Division B3] An extension for a rotary percussive drill comprises a plurality of rods 10 for transmitting percussive forces and a plurality of tubes 11 surrounding the rods to transmit rotational forces rotation being provided from a splined drive 32. A hammer piston 42 acts through a transmission member 36 on the rods 10 and a rotary driving member 33 acts through the splines 32 to rotate tubes 11. Flushing medium cleans the insides of tubes 11 and cushioning pads 43, 44 are provided. Other embodiments are described which function similarly but differ in detail. (For Figure see next column.)
