Abstract
486,588. Percussive drills. PETTIT, W. R. Nov. 4, 1936, No. 30056. [Class 124] [Also in Group X] A set of pneumatic percussive drills are mounted on a trolley 54, each being completely enclosed in a sound-proof casing 51. which may be filled with sound-absorbing material. The inclination can be adjusted by tilting the frame 53, and the height of the casing can be adjusted by the arm 60. Air is supplied to the tools from a compressor 78 and the drills are fed to the work by a fluid pressure piston and cylinder 72. In a modification, one drill and its casing are suspended from a jib carried by a trolley. In a further modification, the drill and casing are carried rigidly by a trolley supported on two wheels. Sealing means such as a rubber tube, or rings of resilient material may be provided at the bottom of the sound-proof casing.
