VALVED COUPLING.

Patented sepaee, 1 91a.

ontinnation o! application Serial No. 569,516, filed J une 29, 1910. Renewed December 27, 1911, Serial N o. 668,097. This application led December 26, 1912. Serial No. 738,616.`

To all whom. t may concern Be it. known 4that I, JOHN N. Timunn, a citizen of the United States, residing at Uniontown, in the county of Fayette and State of Pennsylvania. have invented certain new and useful Improvements in Valved Couplings, of which the following is a specification.

This application is a continuation of the application tiled June 29, 1910, Serial No. 569,516, renewed Dec. 27, 1911, Serial No. 668,097.4

The present invention is designed to pro vide a valve having a novel and improved hose coupling attached thereto, said coupling being constructed so that it. may be manipulated to open the valve, thus reducing the number of parts, and simplifying the structure. A

A further object is to provide a valve which closes tightly Without being screwed down on its seat, and which is guided at both ends, so that it moves squarely to and from the seat.

Vith these objects in view, the invention consists in a novel construction and arrangement of parts to be hereinafter described and claimed, reference being had to the drawing hereto annexed, in Which- Figure 1 is a plan view of the valve..

Fig. 2 is a central longitudinal section thereof. Fig. 3 is a longitudinal section showing a modification.

In the drawing, 5 denotes the casing of the valve. on one side of which is an inletopening 6 having a neck 7 for connection to a pipe, tank or other source of Huid supply. One end of the casing has an opening into which is screwed a plug 8 having at its inner end a tubular stem 9. The other end of the casing has a cylindrical neck 10 provided with a smooth bore 11 which opens at its inner end into the interior of the casing and is formed thereat with an annular valve-seat 12.

In the casing 5 is mounted a valve 13 which is a disk having a beveled edge to iitthe seat 12. If desired, a fiber packing ringmay be applied to the valve, to be replaced when worn, so that it will not be necessary to regrind the valve. This is such a common expedient that it has not been illustrated. From one side of the valve extends a cylinder 14 provided with side ports 15 and working with a sliding fit in the bore 11. The outer end of t-he cylinder is open. From the other side of the valve extends a stem 16 which is guided in the bore of the stem 9,` and between the inner` end of the plug S and the back of the valve is interposed a coiled spring 17, which serves to normally hold the valve closed.

At 18 is indicated a nipple which is coupled to the outer end of the neck 10 in alinement with the cylinder' 14. This nipple is provided for the purpose of connecting a hose 19 to the valve casing, and also for opening the valve 13. The nipple `is connected to the neck 10 by a coupling sleeve 20 which is screwed on the neel: 10, the latter being externally screw-threaded `for this purpose. The sleeve has an internal annular shoulder 21 whichengages an external collar 22 on the nipple. Between the shoulder 21 and the hose 19 is a retainingr washer 23 having a press tit. The inner end ot' the nipple is slightly enlarged and is adapted to enter the bore 11 to engage the outer end of the cylinder l-l, and this portion of tht` nipple has external grooves to receive packing rings 24 which prevent leakage of tiuid through the bore 11 if pressure is kept .in the hose 19. The abutting ends 29 of the nipple and cylinder are beveled and ground so that a tight joint is had.

Upon screwing the sleeve 20 forward on the neck l0 the nipple 18 is carried inward therewith and thus pushes the cylinder 14 inward to unseat the valve 13. The nipple will be advanced untilthe ports 15 clear the valve seat 12 and are in communication with the inlet- 6. The fluid then flows through the ports 15 into the cylinder 14 and through the latter into the nipple 18 and thence into the hose 19. Upon unscrcwing the sleeve 2O the spring 17 closes the valve and returns4 the cylinder and nipple to their normal position, the ports lo being closed by the wall of the bore 11.

The valve 13 is guided on one side by the stem 16 and on the other side by the cylinder 14, by reason of which it will scat squarely, and it closes gradually without a rotary movement, whereby wear is reduced to a minimum.

The valve herein described is simple in structure` and it effectually serves the purpose for which it is designed. The coupling can be. readily applied or removed without. disturbing the valve, and the number of parts is reduced to a minimum by making the coupling the valve opening means. the parts are easily accessible, repairs to be readily made.

Fig. 3 shows a slight modification. In this structure the valve and the cylindrical extension are separate so that either part may be removed for renewal when Worn, Without renewing the other. The valve is a cap Q5 which lits loosely on the inner end of a cylinder 26 corresponding to the extension 14 in the first described structure, and closes said end, and said cap has an annular flange 27 encircling-said end of the cylinder, said flange being beveled to fit the valve-seat 12. A spring 28 holds the cap seated.

I claim:

In a valved coupling, a casing having inthus enabling being loose thereon,

let and outlet openings, the latter having a valveseat, a cylinder slidably mounted in the outlet opening, and having side ports, a cap closing one end of the cylinder, said cap the other end of the cylinder being open, and the cap having an annular fiange which encircles the cylinder and is shaped to engage the aforesaid seat, and resilient means for holding Vthe cap seated on the cylinder and the flange thereof in engagement with the valve-seat.

In testimony whereof I aiix my signature 30 in presence of two Witnesses.
