Compressed air . Claim.— I. In a pneumatic hammer, the combina-tion of a main cylinder provided with a pressure-passage leading to its interior, a barrel on the mainframe or cylinder forming a shoulder as its forwardend, and provided on its interior with a longitudinallyextending pressure-passage, a valve-plug outwardlyprojecting from the forward end of the barrel, ahandle for operating the valve, and a reciprocatinghammer within the main frame or cylinder adaptedto be operated by the pressure admitted by the valve,substantially as described. 8i9,452- CUSHION.

AIR-COMPRESSOR. Ebenezer Hill, Nor-walk. Conn. Filed Jan. 13, 1905. Serial , Claim.—I. apparatus for compressing air hav-ing a low-pressure comj)ressor, a high-pressure com-pressor, a connection between the discharge of thelow-pressure compressor and the intake of the high-pressure compressor, a valve in the connection betweenthe compressors that is closed by an abnormally highpressure beyond the high-pressure compressor, and aninlet-valve connected with the high-pressure compres-sor that is held open, when the pressure between it-self and the valve in the connection between the com-pressors drops below normal as a result of the clos-mg of the connection-valve, so as to render the high-pressure piston ineffective for forcing air forwardwhen the connection-valve is closed, substantially asspecified. 819,674.
