VALVE MECHANISM FOR AIR-COMPRESSORS.

Original application filed October 31, 1906, Serial No. 341,391.

Serial No. 364,516.

To all whom it may concern:

Be it known that l. GEORGE H. Rnrxonns, a citizen oil the United States, residing in lt'l anslield Depot. county of Tolland, and State of Connecticut, have invented a new and useful Improvement in Valve Mechanism for Compressors, of which the following is a description.

This invention relates to valve mechanisms, and particularly to outlet valves, which may be used in any relation but which I have shown particularly adapted to the compression mechanism of a refrigerating apparatus, more particularly shown anddescribed in my application, Serial Number 341,391, filed October 31st, 1906, of which this application is a division.

Among the objects of my invention may be noted the following: to provide an outletvalve, the structure of which is adapted for practically any use, and which, wherever used, will be strong and durable, certain in action and effective for the purposes; to provide an outlet valve, the movements of which are always under comparative control overcome only by the force of the compressed fluid during operation; and to provide an outlet valve mechanism which has its operative movements in right lines without possibility of variation therefrom.

With the above objects in view, and others which will be detailed during the course of this description, my invention consists in the parts, :t'eatures and combinations of elements hereinafter described and claimed.

In order that my invention may be understood, I have provided drawings in which the figure is an enlarged sectional detail of my outlet valve made according to my in vention.

Generally speaking, in my refrigerating apparatus, made the subject of the application aforesaid, the air or gas which is employed as the circulating or refrigerating medium, is pumped or forced into the receiving or return chamber or pipe of a compression mechanism by means of a rumor pump located 1n the bottom of the compression tank. The frame has a hollow head at opposite ends close to the ends of the piston cylinder, providing chambers w1th1n wlnch the air or other gas enters, and in whlch the inlet and outlet valves operate.

The particular invention, of this applica- Specification of Letters Patent.

Pz'utented Oct. to, H910.

Divided and this application filed March 25,

tion, is the outlet valve mechanism which is shown in all its details in the figure. and wherein the valve-head 26 is carried by the stem 27 journaled in sleeve 28, in turn jour naled at its forward end in the spider 23), which latter is peripherally screw-threaded to cooperate with the ring 30; which in. turn is peripherally screw-threaded to cooperate With the wall 81 of the heads respectively containing the valve chambers 8 and 9. The ring 30, at its outer end, is pro vided with a beveled flange 32 providing a seat for the valve-head 26. The other end ofthe sleeve 28 is journaled in the cap 33, which is peripherally screw-threaded at its inner end to cooperate with the head 34 of chamber 9, and is provided centrally with the bore 35, which latter is enlarged at its open end to provide the chamber The sleeve 28 slides freely in the bore 35 of the cap 33, and near its outer end is provided with the collar or flange 37 affording a bearing for the coiled-spring 39, which surropnds said sleeve, and the other end of which spring operates within the chamber 36, the spring thus exercising a normal tendency to force the sleeve outwardly and the sleeve, in consequence, exercising :1 nor-- mal tendency to force the valve-stem outwardly and the valve-head 26 against its seat 32. In the bore of the cap 33, a coiled-spring 40 is located, which cooperates with theadjacent end of the sleeve 28 and prevents the latter from being forced too far into the bore 35, thus preventing the valve-head 26 from having excessive movement away from its seat 32. In other words, the power of the compressed air Will force the valve-head 26 away from its seat 32, thus exerting pressure on the sleeve 28, which in turn will compress the spring 39, the latter having a normal tendency to hold the valve-head 26 against its seat 32; but, should the air pressure be sullicient to excessively compress the spring 39, the spring 40 inthe cap 215 will act a cushion to receive the impact of the end of the sleeve 28, and will prevent too great movement of the valve-head, cushion the movement of the same and prevent the valve parts from rat tling or operating upon each other noisily.

From the above description, it will be seen that among the advantages of my valve mechanism, the following may be particulnrly noted: The entire valve structure is rcmovable or detachable from the frmnework.

spending to the influences of the gas under compression, and its spring mechanism in opposite directions; the valve-head cannot be thrmvn from its seat in operation, nor assume a position such that its operation or action will become defective; and the valve parts, irrespective of the rapidity of their operation, Will be noiseless and cannot chatter.

Having thus described my invention, What I claim and desire to secure by Letters Patent is:

A valve mechanism comprising a frame;

stem; 3 socketed sleeve for receiving said stem; oppositely disposed ournals for sup porting said sleeve; a socket in one of said ournals; a spring located 111 said socket and cooperating with one end of the sleeve; a-

collar on. said sleeve; 5 spring surrounding the sleeve and engaging one end of the co1- lar; and at its opposite end engaging a stationary part.

In testimony whereof I have hereunto signed my name in the presence" of two snbscribing Witnesses.
