FAUCET AND VALVE.

SPECIFIGATIGN forming part of Letters Patent No. 691,569, dated January 21, 1902.

Application filed May 16, 1901. Serial No. 60,468. (No model.)

T0 @ZZ whom t may concern:

Be itknown that I, EDWARD A. POHLMAN, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and useful Improvement in Faucets and Valves, of which the following is a full, clear, and exact description.

The purpose of this invention is to provide a construction of faucets and valves in which the valve-seat is conical and is removable from the barrel or casing of the valve and wherein the valve is spring-controlled and is fitted to the said conical seat.

Another purpose of the invention is to so construct the valve as to prevent concussion or water-hammering and also to provide a bonnet for the valve-casing which Will serve as a fulcrum for the lever which is to operate the valve.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specilication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal vertical section through a faucet and the improved valve applied thereto, the valve being shown seated. Fig. 2 is a section similar to Fig. 1, the'valve being shown as raised from its seat; and Fig. 3 is a detail plan view of the valve-seat,drawn on an enlarged scale.

A represents the barrel or casing of a faucet, and B the tubular stem thereof, which is adapted to be passed through the body to which the faucetis to be attached. The valvecasing at its upper portion is provided with an enlarged `interior chamber C, and below this chamber the valve-casing is providedI with a bore B', preferably of the same diameter as the interior diameter of the stem B. D represents a bonnet, which closes the upper portion of the said casing chamber or barrel C of the faucet. This bonnet D is preferably screwed upon the barrel or casing A, as shown in Figs. 1 and 2, and is provided with a central opening and a depression 10 in its upper surface around the said opening, forming thereby an elevated annular surface 1l at the upper marginal portion of the bonnet. An outlet or nozzle 12 for the barrel or casing A connects with the same at or near the bottom portion of the chamber' C, as is also shown in Figs. l and 2. t

Where the chamber O connects with the boreB the wall of the bore B is provided with a thread 14, which receives the exterior thread of the tubular shank 15 of a valveseat, the top portion 16 of which seat is conical and extends within the chamber C, and this conical upper portion 16 of the valve- "seat is provided with a longitudinal opening 18 at its apex connecting with the chamber or interior of the shank l5. This opening 18 is preferably made rectangular or polygonal,

as illustrated, in order that a suitable tool may be introduced into the opening 18 for the purpose of screwing the valve-seat to place or removing the valve-seat whenthe bonnet D has been taken O from the barrel. The upper conical portion 16 of the valveseat is made flaring to such an extent that at the base an annular shoulder 17 is formed, which when the valve-seat is secured to place has bearing upon the bottom portion of the chamber C.

The valve 19 is provided lwith a conical chamber or opening 20 in its bottom, adapted to conform closely to the outer contoug'` of the conical upper section 16 of the valve-sat, as shown in Fig. 1. The valve is provided with a stem 21, and this stem has a longitudinal chamber 22, 'connecting with the conical chamber 20 in the valve proper, and this chamber 22 in the valve-stem 21 constitutes an air-cushion or air-chamber, preventing concussion or water-hammering. Aspring 23, preferably a spiral spring, is coiled around the stem 21, and this spring has bearing upon the upper surface of the valve proper, 19, and against the bottom of the bonnet D. A lever 24: is pivoted to the upper end of the valvestem 21, which valve-stem extends through the central'opening in the bonnet D, and when the valve is to be opened the lever 24 is depressed, as shown in Fig. 2, and the upper marginal portion 11 of the bonnet serves at such time as a fulcrum.

It is obvious that a perfect contact is obtained between the valve and its seat and that should the Valve-seat become worn orin- IOO jured to any appreciable extent it may be readily removed from the barrel or casing.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a faucet and valve, a barrel or casing, a removable, conical, apertured valve-seat located within the barrel or casing, a valve having a conical chamber adapted to fit to the conical seat, the said valve having also a tubular stem communicating with said conical chamber, which tubular stem provides an aircushion and prevents concussion or waterhammering, as described.

2. In a faucet and valve, a barrel or casing provided with a chamber at its upper portion and a nozzle in communication with the bottom portion of said chamber, a bonnet closing the upper portion of the chamber, a valveseat comprising a hollow shank removably connected with the interior of the casing or barrel just below the chamber therein, and an apertured conical head which extends into the said chamber, the valve having a conical opening in its bottom portion, adapted to receive the conical head of the valve-seat, and a spring-controlled stem for the said valve, which stem has an interior chamber connecting with the conical opening in the valve, the said chamber constituting an air-cushion and serving to prevent concussion or water-hammering, as described.

In a faucet and valve, the combination, with a barrel or casing having a chamber therein at its upper portion, a nozzle connecting with the said chamber at its bottom, and a bonnet closing the upper end of the said chamber, which bonnet is provided with a central aperture and a depression in its upper surface around said aperture, of a removable valve-seat, comprising a hollow shank having a screw connection with the casing or barrel at a point below the chamber therein and an apertured head of conical shape,which head extends Within said chamber and has bearing upon the bottom Wall thereof,a springcontrolled valve located Within said chamber, having a conical opening which receives the conical section ofthe valve-seat, a valve-stem for the valve, which passes through the opening in said bonnet, the valve-stem being hollow and the hollow portion connected with the conical opening in the bottom of the valve, and a lever pivoted to the upper portion of said stem, capable of having bearing upon the upper marginal portion of said bonnet, for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDWARD A. POHLMAN.
