Abstract
145,562. Bailly, A. Feb. 14, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Percussive hand tools; loose tools and bits, retaining.-In a pneumatic hammer, fluid from an inlet f acts constantly on the annular area d and moves the piston c to the right, some of the fluid then passing through port h to act on area l and move the piston to the left; this fluid, after acting expansively, is exhausted when a tube m is uncovered by the piston. In a modification, the tube m is extended and exhaust effected through lateral ports' therein. The tool e is retained in the cylinder by a cap A held to the latter by bayonet-joints and pressed by a spring F. The tool co-operates with a ported ring s controlling ports w in the cylinder; during normal working, the space r communicates freely with the atmosphere, but when the tool is not pressed against the work, the ring s closes ports w and cushioning occurs in spaces r and g.
