Abstract

941,548. Percussive drills. EAST MIDLANDS GAS BOARD, and J. R. WHITTING- HAM. Oct. 20, 1960 [Oct. 21, 1959], No. 35665/59. Heading B4C. A pneumatic drill provided with a carrier engaging the work adjacent the drill has means for effecting relative movement of the carrier and drill to move the carrier towards the work and remove the drill from the work. The carrier comprises wheels 37 mounted on a piston-rod 21 extending from a cylinder 19 attached to the drill body 10. During drilling the top of the cylinder is vented, but when the drill 12 is being withdrawn air is supplied to the top of the cylinder by operating a lever 27 mounted on a handle 16. The wheels may be replaced by a foot 39.
