Be it known that 1, MICHAEL J. Mo- ANENY, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented a new and useful Improvement in Air-Hose'Connecters for Inflating Pneumatic Tires, of

which the following is a specification.

My invention relates to an improvement in the commonly used connecter-device provided on the end of a hose leading from an air-pressure supply (as' at filling-stations) "or a pump, for application. to the projecting f valved tube on a pneumatic tire forinflatin'g f the latter; and its is fully explained inthe following description and illustrated 'in the 21000111 an 111 i .dI'EL W 111 111 W h1Cl1 Figure 1 shows my improved. devicein; side elevatlon, and Figure-2 1s an enlarged 1 the base of which extends a relatively short air-passage 7 terminating in a tubular valvechamber 8 of a valve-device, the chamber projecting at a right-angle (downwardly) from one side of the casing and having its outer end closed by a screw-plug 9. The valve-chamber 8 communicates through a centrally perforated wall 8 at its inner'end with a tubular extension 8, similarly projecting from the casing 3, butfrom its opposite side and provided with a seat 8 at its open outer end. -The casing terminates at its opposite or forward end in an externally-threaded nozzle 10, on which is screwed a knurled cap 12, which confines against a shoulder 11, formed in the nozzleend, a gasket 13 of rubber or other suitable material. From the inner end of the valvechamber extension 8 there extends lengthwise in the casing an air-passage 7, as a continuation of the passage 7 and communicating at its outer end portion with an airchamber 14: in the nozzle (extending over the gasket 13 therein), through a pair of similar branch air-passages 7". The chamber 8 contains a valve 15 seating against the passes through the ar -a e wall into the ya lvechainber extension .8 wherein it scr'ewsinto the inner end of an enlargement; 16 of the valve-stem, terminating at its outer end a. button provided on its u d r .sid with a fa n 1. Prefera l .Q

Withmy ri p..r d.conns t n QPmtive .aii s2 nt.fa lll .W '.8 a d carried on T the inner end of athreaded stem 16 which PQSi Qn, rpr s u e om t me o firmly2l ld ith lva v normally a ains its Seat-t6 shut Qifi th i191? 9 nomiir ssed T 1 1 th eiti s 1 1 its purpos th zz i applie l'ft t e? rd nary prpisc ins valved tube (not shown) of aftireto beinflated, in' a manner to fencircle'tlie tube. Th reupqn t eopera q l depre sa ithe v v stem at the button v 17, thereby bearing the facing 18 against the seatfitto seal the-outer end of the chamber 8 and removingthe Valve 15 from v 1 st st n t passa which then communicates through the pert n th Wall 8" wit Pas g .7 j and .7; and the air=cha1nber 14, in which latter it so {compresses the gasket 13 about the tire :valve-t'ubefas to" cause it to closely and tightly hug the tube, when the airpressure entering,the v latter through the nozzlelO opens the-tire-valve. This close,hugging by the, gasket prevents waste of air from the supply ,by.leakage.

After inflationlof the tire, the operator releases the ,buttonto permit thejairpressure T from the source of supply" to reseat the valveil5 andshut O fi the fio'w, and the resultant; rise rof the button off its seat 18- releases' the airpressure on the gasket 13 .fro'm'rthe' chamber 14; by way ofithe passages 7 7 and valve-clianiberjSi about;the stem in the latter, thereby permitting the gasket 15 to expand or relax and loosen about the tire-valve tube and enabling the connecter to be withdrawn without oflering resistance.

The advantage of thus releasing the air is that of avoiding having to wrench the connecter from the the tire-tube after the inflation, which is ordinarily the case with connectors in common use to the injury of the gasket, causing impairment of the operation of the connecter with resultant waste of air-pressure and early destruction of the gasket, requiring the expense of replacement thereof. It even happens sometimes that the gasket hugs so tightly as to prevent withdrawal of the connecter in .time to prevent bursting of the inflating tire by the excessive pressure introduced therein be-- cause of inability to shut it off with the connecter operating. All these objections are overcome by my improvement.

I realize that considerable variation is possible in the details of the construction herein shown anddescribed, and I do not intend to limit my invention thereto except as pointed out in the appended claims, in which it is my intention to claim all the novelty inherent in the device as broadly as is permitted by the state of the art.

I claim:

1. A tire-inflating hose-connecter having an expansible and contractible gasket in its nozzle, to which leads an air-passage through the connecter whereby supply of air under pressure to said nozzle may cause said gasket to expand, and a valve-device interposed in said passage for opening and closing it to the supply of inflating air and including means operatingby closure of the valve to vent the introduced air ahead of it away from the gasket.

2. A tire-inflating hose-connecter having in its nozzle an expansible and contractible gasket and an air-chamber extending over the gasket, to which chamber leads an airpassage through the connecter whereby air admitted to said chamber may cause said gasket to expand, and a valve-device interposed in said passage for opening and closing it to the supply of inflating air'and including means operating by closure of the valve to vent the introduced air ahead of it from said chamber.

3. A tire-inflating hose-connecter having in its nozzle an expansible and contractible gasket to which leads an air-passage through the connecter whereby air under pressure admitted to said passage may cause said gasket to expand, and a valve-device interposed in said passage, normally closing it to the supply of inflating air and provided with means for closing said passage to the atmosphere when the valve is opened and opening said passage to the atmosphere when the valve is closed.

4:. A tire-inflating hose-connecter having in its nozzle an expansible and contractible gasket and an air-chamber extending over the gasket, to which chamber leads an air passage through the connecter, and a valvedevice comprising a wall-divided valvechamber extending transversely through said open end by depressing the button to unseat the valve for opening said passage to the supply of inflating air whereby pressure admitted to said air chamber may cause expansion of said gasket and venting of the air from said passage may allow the same to contract.

5. A tire-inflating hose-connecter, having in its nozzle an expansible and contractible gasket and an air-chamber extending over the gasket and to which leads the forward of two relatively-ofl'set sections of an airpassage through the connecter, and a valvedevice comprising a valve-chamber formed of tubular sections extending from opposite sides of the connecter-casing between the adjacent ends of said passage-sections, a dividing wall' in one of said chambersections at which the rearmost of said passage-sections ends, the forward passagenamed chamber-section to form therewith an interposed air-venting passage, said stem carrying on its outer end a button for closing the open chamber-section end by depressing the button to unseat the valve, whereby pressure admitted to said air chamber may cause expansion of said gasket and venting of the air from said passage may allow the same to contract.
