Abstract

1,123,178. Percussive tools. HUGHES TOOL CO. 6 Feb., 1967, No. 5644/67. Heading B4C. A percussive tool 10 comprises a driving shaft 20 mounted in a housing 12 and having at least one cam follower 22 adapted to cooperate with a cam surface 34 formed on a hammer 24 in order to raise the latter against the action of a spring 30, the spring having its ends connected by threads 40, 42 with the hammer and housing respectively. The shaft 20, which may be rotated by means of an hydraulic motor 18, is provided with a bore (46, Fig. 3) in which is mounted an axle 44 carrying a pair of cam followers 22 adapted to ride on the cam surfaces 34. The tendency for the hammer to rotate during operation is resisted by means of the spring 30 being anchored at its ends by the screw-threads 40, 42. The moving parts of the tool are lubricated and cooled by feeding hydraulic fluid into the interior 82 of the housing via an inlet 76 and an outlet 78.
