GOTTLIEB SCHNEIDER, OF BLUFFTON, INDIANA, ASSIGNOR TO R. G. MARCY MFG. CO., OF BLUFFTON, INDIANA.
AIR-VALVE.
SPECIFICATION forming part of Letters Patent No. 728,810, dated May 19, 1903. Application led November 10, 1902. Serial No. 130,730. (N model.)
v a citizen of the United States, residing at Bluffton, in the county of Wells and State of Indiana, have invented a new and useful Air- Valve, of which the following is a specification.
This invention relates to air-valves.
The object of the invention is ina simple, ready, thoroughly-feasible and practical manner. to supply air as requisite'toa tank or other receptacle containing liquid when a faucet is opened and to cut off the supply of such air when the faucet is closed.
With theserand other objects in-view, as
will appear as the nature of the invention is,
better understood, the same consists in the novel construction and combination of parts of an airvalve,.as will be hereinafter fully described and claimed.
In the accompanying drawing, forming a part of this speciication, and in which like characters of reference indicate corresponding parts, there isillustrated one form of embodiment of invention capable of carrying the same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof, and in this drawing the gure is a view in vertical longitudinal section through an air-valve constructed in accordance with the present invention.
The valve comprises a nipple or shield 1, a plug 2, a stem 3, arranged within the plug and carrying a valve 4, and a valve-stem-actuating spring 5. The nipple or shield is conoidal and is provided at its upper endwith an airinlet 6 and at its lower portion with a lateral enlargement 7, which is externally threaded to permit of stableattachment with the tank or other receptacle with which it is designed to be used, such holder being designated by 8. The nipple is also provided with a polygonal portion 9 to be engaged by a wrench in positioning it within the holder. The interior of the lower. portion of the nipple is threaded for engagement by the plug 2, which latter has polygonal faces 10, also to be engaged by a wrench.
The stem 3 is provided with a channel or bore 11, which communicates with a lateral end of the stem and through which the airA taken in through the inlet 6 of the nipple escapes to the interior of the holder. The bore of the plug is constricted at its lower end at 13 to fltaround the stem and present a guide therefor and also to provide a bearing for the lower end of the spring 5, the upper end of which bears against a disk 14, held in position upon the stern in this instance by upsetting the upper end thereof, las at 15. The lower kend of the' plug is provided with a seat 16, `which is preferably triangular in crosssection, thus to Vpresent a reduced edge to engage the valve 4, which latter is of -rubber and is held in position upon thev stem by a head or disk 17 integral with the stem. The stern is fitted within the bore of the plug in such manner as to be delicately responsive to atmospheric'pressure and at the same time be'free from liability of becoming bound in use. This valve is adapted especially for use where air-pressure is used in pumping, as in connection with pressure-tanks into which liquid is pumped under high pressure. When a faucet is opened to Withdraw the liquid, atmospheric pressure instantly operates to depress the stem against the pressure of the spring, whereupon air will pass down through the bore 11 and out through theescape-opening 12 into the holder, and this will continue so long as the faucet remains open. As soon as the faucet is closed the spring 5 instantly performs its function and forces the valve against the seat, thereby cutting off the supply of air.
The employment of a nipple is of importance, inasmuch as it positively protects the stem against injury and also precludes to a large extent entrance of foreign substances which might tend to clog the stem and thus prevent its operation.
Having thus described the invention, what is claimed is- An air-valve comprising'a'conoidal nipple or shield provided at one end with an air-inlet opening, at its other end with interior and exterior threads, and intermediate of its ends with wrench-faces, a plug engaging the IOO interior threads and provided at its lower end with a knife-edge seat and intermediate of its ends with wrench-faces, a spring-pressed stem mounted within the plug and provided with an air-channel, a valve mounted upon the stem, and a head integral with the stem for forcing the "alve against the seat.
In testimony that I claim the foregoing as my own I have hereto aixed my signature in the presence of two witnesses.
v GOTTLIEB SCHNEIDER. Witnesses:
E. L. MURRAY, .JAMES P. HALE.
