WILLIAM F. MEISTER. OF MARIETTA. OHIO. ASSIGNOR TO THE PATTIN BROS. COMPANY, OF MARIE'I'TA, OHIO, A CORPORATION OF OHIO.

VALVE FOR AIR-COMPRESSORS, 8w.

Application filed August 11, 1915.

To (db/710m it may concern Be it known that I. ll'immut F. M1cisTEn, a citizen of the United States. and resident of Marietta. in the county of \Vashington and State of Ohio. have invented certain new and useful Improvements in Valves for Air-(ompressors. &c., of which the following is a specification. V

The object of this invention to provide a simple and highly etlicient valve for compressors. blowing engines. etc.. the alve being constructed of relatively thin flexible metal which provides its own spring action. avoiding the use of separate springs commonly employed. The 'alve is maintained in proper working condition. notwithstand ing very frequent and rapid vibrations to which it is subjected. by exposing its flexing portions to the air which is admitted or d ischarged through the valve. thereby preserving the temper of the metal and rendering it responsive to as rapid action as may be re- 'quired.

In the preferred embodiment of the invention the valve is of disk form. with a plurality of laterally separated port-covering portions radiating from a central securing portion. whereby each port-covering portion may flex independently with a total absence of buckling tendency.

In the accompanying drawings. Figure 1 is a longitudinal section of one end of a compressor equipped with the improved valve. the inlet valve being mounted on the co'n'lpresson cylinder head. and Fig. '2 is an elevation of the cylinder head with the inlet valve attached thereto. Fig. 3 is a view similar to Fig. l..illustrating the inlet valve mounted in the side of the cylinder. Fig. l is a detail view of the lIll] )1O\'0(l YtllVtRS111)- plied to the compressor outlet.

Referring to the drawings. the compressor cylinder 2 is cored toprovide the usual air inlet channel 3 and outlet channel 4. ln the adaptation shown in Figs. 1 and 2 cylinder head 5 is cored to tornrthe encircling air channel 6 with which inlet channel 3 is in communication, and with ports 7 connecting channel 6 with the cylinder. The inner face of head 5 comprises a support for the inlet valve. 1

The valve is formedof a sheet of thin resilient metal. and in the arrangement shown is of disk-like form and has a hollow hub portion 8 adapted to fit around boss (1.

on the inner face of head 5 and secured to the head by screws 7). Thedisk-like plate is formed with radial slots 9. forming a series of independently flexible valve segments. Each segment is cut out or apertured at 10, thereby leaving the'marginal portions 11 which connect the port-covering outer por- 'tion 12 of each segment with supporting portion 8. lVith the valve formed of resilient sheet metal. portions 11 constitute spring arms for a ilording the port-covering portions 12 sensitive movement in response to air pressure. the direction of such pressure being determined by the movement of piston 13. As illustrated in Fig. 1 the end face of cylinder 2 is recessed at 1+ to receive the valve and to provide a stop for limiting the inward movement of the segments on the filling stroke of the piston 'as in Fig. 1. and on the return or discharging stroke ports 7 are closed by the port-covering portions 12 under thev spring action of. arms 11 plus the air pressure.

The discharge valve 15, controlling communication with outlet channel :l. is preferably arranged at the top or at one side of the end ot" the cylinder and' is secured to theremovable seat is ported at 1T tor t he pas- The discharge valve. shown in detail in :Fig. l. is of the same construction as the above described inlet valvc excepting that its center is solid save for an aperture to pass a securing screw 18. the rim-like peripheral portions 12 being adapted to open "and close ports 1?. as will be understood. Seat It) with the valve sc cured thereto is removably mounted in the angular end otchanncl -lwhich communicates with the cylinder. being inserted through an cxtcrnal opening closed by cap 19 and held in place by screw 20 adjustable through the cap. The cylinder end may e equipped with one or more discharge valves as may be necessary.

in the adaptation shown in Fig. S. the inlet valve is shown at one side of the cylinder at '11 in the same relative position as ing and preserves their temper.

It is characteristic of the valve, both inlet and discharge,- that thespring elements ,for maintaining it normally in port-closingposition and for opposing opening movement thereof are embodied inthe valve itself, being the radial riin' -like, portions lljwhich readily flex in response to the opening" and closing movements.- And as these flexing. portions are directly in the path of the air flow, inward or outward, controlled by the valve, the cooling effect prevents overheat- VVith the valve divided nto segment-like sections by slots 9, each section is of su ch the action of the suction strokes of the pis-.

ton and closing as quickly on the compres sion strokes. While only a. portion of a compressor cylinder is shown, it will be understood that the improved valve may be utilized. for either single or double-acting compressors, in the latter type each end of the cylinder having the same valve equip-g ment. It will also be understood that the invention is well adapted for blowing engines and other: machines -in whi'ch sensitive qi'lick-acting 'valves are-required- 9 I claim:

'1. A valve for compressors, etc., formed of relatively flexible metal and consisting of a central supporting and securing portion,

=.a.series of segmental port-covering por-. ,tions separated from each other for 1ndependent flexing and w1th spring armsuntegral with the supporting portion and with the port-covering portions, each segment of the valve comprising several of said spring.

arms andbeing open for the passage ofair between its said port covering and'supporting portions and between said arms.

2. A valve for compressors, etc., formed of a disk of'thin flexible spring metal cut to form a series of independently flexible .segments and a supporting and securing portion common to and integral with all of said segments, each segment having a port covering portion atits free end and radial rim arms connecting the port covering portion with the supporting and securing portion, each segment being open between said arms and said portions, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
