Abstract
915,852. Percussive tools; working hard materials. ALPINE A.G. Dec. 9, 1960 [Dec. 10, 1959; Sept. 3, 1960], No. 42440/60. Class 124. In a device for breaking hard materials and comprising a tool 4, such as a chisel, axially movable in a casing 5, 7, and a powder charge 2 exploded by a cap 3 to move the tool, the chamber 1 holding the charge moves away from the tool during combustion of the charge. The tool is slidable in the casing part 5 and is retained in the device by a guard 25, 26 which is moved against a spring 27 to push the tool back into the casing part where it is held before firing by a fastening 29. The chamber 1 is slidable in the tool and has gas vents 23 operative when the tool is fully extended. The cap is ignited by a blow from a striker 6 resultant on a blow on a projection 12. The recoil of the device is absorbed by the striker, and by a sleeve 16 having handles 21 sliding on the casing part 7 against a spring 17. In modifications the chamber 1 may be loaded into the device by means of a lateral aperture and is disposed to the rear of the tool.
