VALVE.
Patented Feb. 20, 1894.
ATTORNEY JOHN F. IVES AND FRANK B. OOLMAN, OF NEW YORK, N. Y.
VALVE.
SPECIFICATION forming part of Letters Patent No. 515,290, dated February 20, 1894.
Application filed April25. 1893.- Serial No. 471,759. (No model.)
T0 on whom it Jnay concern.-
Be it known that we, JOHN F. IVES and FRANK B. OOLMAN, residents of the city, county, and State of New York, have invented certain new and useful Improvements in Valves, of which the following is a full, clear, and exact specification.
Our invention relates to improvements in valves which are particularly adaptable to use in connection with pneumatic bicycle tires, siphon bottles, water faucets and the like.
Our invention consists of the improvements hereinafter fully described.
The improvements constituting this invention are particularly adapted to be used in connection with the patent, granted August 29, 1892, and numbered 481,762, to John F. Ives and Frank B. Colman.
The objects of our invention are first, to improve the construction of the rubber piece which forms the valve proper, which improved construction facilitates the more perfect operation of the said valve, and, second, to provide in connection with the caps for the valve, an-integral screw-driver and deflating tip to be used in operating the valve.
Our invention is illustrated by the accompanying drawings in which- Figure l is a vertical section of the entire device, illustrating the valve open and the cap shown as inverted with the integral screwdriver and deflating tip in position for operation. Fig. 2 is a side elevation of the cap, integral screw-driver and deflating tip. Fig. 3 is a side elevation of the cap, integral screwdriver and deflating tip, illustrated as turned one quarter of a revolution from Fig. 2, and Fig. 4 is a vertical cross-section of the valve mechanism and the co-operative parts showing the valve in the closed position. In this figure the upper and lower parts of the valve stem are broken away.
Similar letters refer to similar parts throughout the several views.
A is a cylindrical valve-stem the upper portion or outlet of which is preferablythreaded on the outer and inner surfaces, as shown in Fig. 1.
the free passage of air or liquid.
B is a perforated shank which is preferably screw threaded to permitdts insertion into the valve-stem A.
D D are suitable grooves or perforations formed in the sides of the shank B to permit In the upper end of the shank B, we preferably cut a slot E, adapted to receive any suitable screwdriving device used to insert or remove the said shank B.
F is the, valve proper constructed of an elastic material, preferably rubber. This valve F is suitably secured to the lower side of the shank B. A substantially cylindrical hole extends part way down through the valve F to receive or permit the introduction of the deflating pin or plunger G. This plunger is introduced through a longitudinal perforation in the shank B. r
One of the mainimprovements is to so construct an elastic valve that it will offer less resistance to air or liquid that is forced past it from the outside and that will operate to' prevent its return more quickly and effectively than the elastic valve described in the above referred to patent. WVe therefore form within the valve, preferably at a point adjacent to its widest part, the recess H having preferably inclined walls, as shown in Figs. 1 and at. The effect of this recessH within the valve is to afford what may be termed a compound leverage, when pressure is applied against the lower end of the valve, as shownin Fig. 4t,this compound leverage tending to force the thinner portion of the exterior sides of the valve away from the center of the valve and tightly against the interior surface of the valve-stem A,.thereby securely checking the outward passage of the airor liquid. It has been found by experiment that it requires about fifty per cent. less pressure from above to force air or liquid past a Valve of this improved construction, inasmuch as this construction permits the valve to more freely stretch.
I is a cap adapted to be attached to the upper end of the-valve-stem A.
J is a projection extending from the cap I, to form a deflating pin which may be pushed through the hole in the shank B to elongate the valve to permit the outward passage of the air or liquid. (See Fig.1.) Byfiattening out that portion of the projection J which is adjacent to the cap I, a screw-driver L is formed integral therewith. This screw driver may be used in removing the shank B and valve Ffrom the valve-stem A. Itis obvious that the deflating tip J may be lengthened to serve the purpose of elongating the flexible valve, in place of the plunger G. (See reference letter J Fig. 4.)
Having thus described our invention, what we claim, and desire to secure by Letters Patent, is 1. A valve consisting of an inflexible metallic shank carrying a flexible cap in connection witha hollow valve-stem, said flexible cap having the recess H, substantially as and for the purpose described.
2. An automatic valve consisting of an inflexible or metallic shank B carrying a flexible cap F, in combination with a hollow valvestem A, said flexible cap containing the recessed chamber I-I, surrounded by inclined walls to cause a compound leverage, substantially as and for the purpose described.
3. An automatic valve consisting of an inflexible or metallic shank 13, carrying a flexible cap F,in combination with a hollow stem A, said flexible cap F having its recess, through which the deflating pin passes, enlarged at its lower extremity so as to leave the adjacent surrounding wall thinner and thereby cause a quicker action of the valve, substantially as described.
4. In an automatic valve the valve-stem A, the flexible valve F, and the cap I having the deflating pin J, and the screw-driver tip L, formed therewith, substantially as described.
5. The combination of an automatic valve as described, having a cap I, with a screwdriverand deflatingtip formed integralthere- Wllll, substantially as described- .I. F. IVES. FRANK B. OOLMAN.
