AIR COMPRESSOR AND THE LIKE- APPLIOATION FILED JULY 15. 1904.
a "i v s lm Masses I 3513M (ltkpzmew PATBNTED FEB. 26, 1907.
fw /aw understood from the drawings and above description. In Fig. 2 the piston B is shown as approaching the end of its compressionstroke to the left, in which position the valve e at the right-hand end of the cylinder is in position to open the cylinder behind the piston to the suction, and the valve e at the lefthand end, or in advance of the piston, is just closing the cylinder to the discharge, and the ppppet-valves f, which have been opened When the cylinder-pressure during the stroke reached a point above the delivery or receiver pressure, are still open.
In Figs. 3 the part at both ends of the cylinder are shown in their position when the 'ston B has reached the end of its stroke and 13 about to reverse, the left-hand end of the cylinder being closed to the discharge by the lobe 2 of the valve e and the valves f at this end of the cylinder'being still open, while at the right hand-end of the cylinder the lobe 2 ofthe valve c has closed the cylinder-port and the valves f are closed. On the reversal of the piston B the valve e at the left-hand or suction end of the cylinder moves farther to the left, so as to connect the suction c with the cylinder through the valve-chamber d, while this valve e still closes the cylinder to the discharge, and the valve e at the righthand or compression end of the cylinder is moved at the proper time to open the cylinder to the discharge, except as the discharge isclosed by the puppet-valves until the pressure in front of the piston exceeds thedischarge-pressure and opens the puppet-valves.
It will be understood that the invention is not limited to the special form of valves or air-passages nor to the special means for operating the positive valves shown and above described; but the invention may be embodied in constructions employing other ar rangements of the valves and a1r-passages and other means for operating the mechanically-actuated valves.
The term mechanically-actuated valves used in the specification and claims is to be understood as meaning valves that are opened and closed by connections with the compressor or pump shaft or other driven member, so as to be positively opened and closed at fixed points in thestrolie as distinguished from valves that are opened or closed by the pressures of the compressor or FREEZE What we claim is- 1. In an air or gas compressor or pump, the combination with the cylinder and its in-- let and discharge passages, of spring-closed puppet discharge-valves in the dischargepassages, mechanically-actuated valves between the puppet-valves and the cylinder controlling the discharge passages, and means for actuating said mechanically-actuated valves to open the discharge-passages at a fixed point and to close the discharge-passages at the end of each compression-stroke and before the closing of the puppet-valves, and maintain the closing of the dischargepassages on the reversal of the piston, where by a slow-closing movement of the puppetvalves is secured and the puppet-valves are cushioned in closing, substantially as described.
2. In an air or gas compressor or pump,
the puppet-valves is secured and the puppetvalves are cushioned in closing, substantially as described.
In testimony whereof we have hereunto set our hands in the presence of two subscrib ing witnesses.
