-WII'LIAM R; BUYER-OF WILKFS-BARRE, PENNSYLVANIA.

car ron PNEUMATIC-TIRE vA'Lv'es.

To all whom it may concern:

Be it known that I, WILLIAM R. Rome, a citizen of the United States of America, residing at Wilkes-Barre, in the county of LuZerne and State of Pennsylvania, have invented certain new and useful Improvements in Caps for Pneumatic-Tire Valves, of which the following is a full, clear, and exact description.

his invention relatesto caps for pneumatic valves, and its chief object, briefly a' cap which will permit inflation or deflation of the tirewithout removal of the-cap, inflation being accom plished'merely by pressing the air hose nozzle upon the cap itself. A further object is p to provide a cap which,.although permitting 1 nally, so as to be inflation or deflation Withoutremoval, will obviate the'necessity of using the customary dust cap. Still another object is to provide for the purpose described a device of simple character which can be manufactured at relatively low cost. To this and other ends the invention consists combinations hereinafter described.

In the preferred \form of the invention I provide a member in the form of a tubular nipple, which is at one end threaded interscrewed down firmly upon the usual reduced outer end of the valve stem. Secured on the 'outerend of the nipple in any convenient manner is' an open topped cup, and in the latter is asliding rod which extends through the bottom of the cup into the nipple, and can be depressed to depress the valve plungerof the valve stem. The plunger actuating rod is normally held in vertical position by a helical spring surrounding it, and

on its top is pivoted a short armcarrying on its outer end a convex bead or button. Enclosing. the to slide on the neck of the mpple is an in: verted cup having at its outer end an air port with which the aforesaid button cooperates as a closure. The spring serves also to hold the button seated in the air port and to hold the cap in raised position. When, however, the cap is depressed. against the tension of the spring, the button or closure is f cammed out of the air port and the rod is depressed, thereby depressing, the, valve plunger and opening a path for air into or out of the tire.

The embodiment outlined above is illustrated. in the accompanying drawings, in which V Fig. 1 is a sectional view showing the de- Specification '1 Letters -Patent.

vice mounted onthe valve stem of a pneumatic tire, with the parts in their. normal positions, the cap and rod being raised and the air port closed,

Fig. 2 is a sectional view similar to Fig. 1, but showing the cap and rod depressed andthe closure cammed out of the air port. Fig. 3 is a side view showing thev cap locked in depressed position for deflation of the tire.

-Fig. 4 is a sectional view illustrating a modification of the form shown in, Fig. 1. Fig. 5 is a sectional view of the form illustratedin Fig. 4, but showing the cap'and rod in H depressed position with open. A g

The device 10, preferably in theform of a tubular nipple, has its lower end threaded on the inside and when in use is screwed upon the reduced outer end 11 of the valve 'stem 12, the nipple ter.

On top of the nipple or device 10 is a cylindrical cup 15 having on its bottom a neck 16 by which it is secured in place. This cup may be made of metal, as are the other parts described, but preferably it is composed ie is yielding but yet rather stiff so as to give the cup a certain amount of rigidity- In the cup 15 is a slidin 17 extending into the body of the nipp e, so thatwhen the rod is depressed its lower end, which may be enlarged for the purpose, indicated at 18, will engage the valve plunthereby openas will be readily understood. is normally held against-the neck l6 by the tening the valve, The head 18 slon spring hereinafter air from the tire, cannot escape through the neck 16, leakagearound the bottom of the nipple being prevented by the gasket 14 already descrlbed. I

The rod 17 is. provided with a T-head 20, onwhich is pivoted a'short arm 21 termi mating in a convex button 22. ing an air port 24 is provided to enclose the cup and the inner rod, the'cap being fitted y to thecup but adapted to slide very thereon. At its bottom the cap has a tica l exclude water, dirt, or other foreign mat-5 described, so that even if the valve in the stem 12 be defective,

A cap 23 havflange 25 which, in cooperation with a bead of the nipple prevents'remo'val oi the cap. The flange 25 may usually be formed byspinning the outer end of the cap vided on the rod of the nip'ple when the cap is'depressed, as

The-rod 17 tion by a coil spring 2 the'lower end of which bears ona metal washer 28 in the bottom ofthecup. I At the top the spring engages the T-head 20 and'has its extrem1ty 29 extended into contact with the closure button 22, so that normallyrthe parts'willbe held inthe position illustrated in Fig. 1,

that is, with the cap and rod raised and with p ithe Closure 22-held yieldingly 1n the air port. g

It will be observed that the closure 22 is convex and that the edges of the air port ,2 l are beveled. Consequently, depressed the rod 1 7 will pressed also," but the closure 22 will be cammed out of the airport, the arm 21 rocking on the T-head 20 against the tension of the spring 29. .Theparts are then'in the position shown in Fig.2 and are caused to assume such position i of the air-hose is in practice applied to the 23 and pressed: down with sufiicient force to overcome the tension of the spring. To permit deflation of the tire when desired, without the necessity o holding the cap down,

5,"the inner cup 15 (Fig. 1) is omitted, and

in lieu of the lower head 18, whichwhen the parts are raised is seated against the bottom of the neck 16, a tapered plug 32 is properedseat 33 in the neck of the nipple 1,0. I also provide on t a. shoulder 3 under whichmay be placed a asket y3 5 to cooperate with the upper end in' Fig. 5, to open the tire valve.
