UNITED STATES PATENT OFFICE;
AUSTIN L. WEBTZ, OF PHILADELPHIA, PENNSYLVANIA, ASSIGKOB O1! ONE-BALI TO- MORTIMER C. ROSENFELD, OF CLEVELAND, OHIO. I
VALVE.
Application filed August 6, 1924. Seriallo. 130,344.
This invention relates to an im roved check valve or so-called foot valve an while the same is applicable to many purposes, it
i is especially suitable for use inconnectlon with the gasoline pumps of filling stations, the same being adapted to be app ied to the lower end of a riser which leads from the storage tank to the pump, and serving to prevent the return flow of gasoline from the to pump to the tank when the operation of the pump ceases.
Valves of this class which have heretoforebeen emplo ed with gasoline pumps invariably leak, allowing the contents of the pump to gradually recede after each operation and thus being responsible for short measure.
It is the primary purpose of my invention to overcome this difiiculty by providing a check or foot valve which is absolutely leak proof and yet which operates with ease.
Further objects are to provide a valve of the aforesaid class which is comparatively simple and inexpensive, and is so designed as to expedite manufacture and facilitate assembly and disassembly.
v The foregoing objects, with other and more specific ones which will appear as the description roceeds, are attained in the construction illustrated in the accompanying drawing wherein Fig. 1 represents a central 7 vertical section through the valve, showing the same closed; Fig. 2 is a similar view,
' showing the valve open; and Fig. 3 is a horizontal section on the line 3--3 of Fig. 1. 5 i The valve body or casing 1 has a cylindrical interior that is divided into a guide portion 2 and a receiving chamber 3 forthe piston-like valve member 4. The valve memer is provided with circumferential grooves that are occupied by packing elements 5 in the nature of ex ansible piston rings.
' The lower on of the body or casing 1 is externally threaded for the application of an annulus 6 ineor orating a tapered valve seat 7 wherewith t e correspondingly tapered edge ortion of a pad 8 is. adapted to cooperate w en. the valve member occupies closed position. The pad 8 is of suitable packing material'and its edge portion, being compressible, assumes the exact contour of the seat 7, thereby assuring a tight seal. The pad is secured to the valve member 4 by means of a screw 10 that is threaded into a thickened portion of the bottom wall of the valve member, and'aplate 11 isshown as interposed between the head of the screw and the pad.
An annular cap 12 is adapted to be screwed onto a threaded extension .of the;
sure the opening of the valve being kept clear.
- A suitable number of ports or passagewavs 15 extend vertically, through the wall of the body of the casing 1 from a point below to a point above the guide 2. The aggregate ca or greater than the openin of the valve 4 VVhil e ordinarily the valve member. will gravitate to closed position, especial] under the weight of the sustained column 0 liquid,
capacity of the main b0 y.
I may include a spring 16 for assisting in closing the valve, the same being shown as compressed between the bottom wall of the valve member and a plurality of lugs 17 which project inwardly-from theupper end of the guide 2. A flange surrounds the upper end of the guides and serves as a stop to limit the upward movement of the valve member or piston 4. i
When the pump is operated, suction is created above the valve and the member 4 is retracted within the guide 2, to the position shown in Fig. 2, thereby opening the inlet end of the valve and uncovering the lower ends of the .ports 15, permitting the liquid to pass freely through said ports and on to the pump. As soon as theo ration of the pump ceases, the valve mem r will drop to its closed position, as shown in Fig. 1, assisted by the spring 16.
pacity of the ports 15 is preferably equal to.
Attention is called to the fact that when i of 1i uid past the valve member, the pad 8 may included as an additional safeguard.
My improved valve,'considering its efiiciency, is very simple and comparatively cheap of manufacture. The body and the piston-like valve member are adapted to be cast in accordance with prevailing practice, the ports 5 being cored. The only machine work required on the body is the threading of its lower end for the application of the annulus 6, and the internal thrcading of its p llposite end for application to a riser or the 1 e. endinwardly to the upper end of the guide 2. The valve member is turned down for a sliding fit within the cylindrical chamber 3 and guide 2, and is groow'd for the reception of the packing rings 5. When the parts are so finished, the valve member, with the packing rings 5 and pad 8 applied to it, is inserted into the cylindrical chamber 3; the annulus 6 is screwed onto the end of the body, and before or after the annulus is so placed upon the body, the cap 12 is applied to the annulus with the screen 13 in place. v
Having thus described my invention, what I claim is V 1. A valve of the class set forth comprising a body having a cylindrical interior, longitudinally spaced portions of which constitute a guide and a chamber for the reception of a valve member, said chamber opening throughone end of the body, an annulus applied to said end of the body and incorporating a valve seat adjacent the end Its interior is reamed from the lower of said chamber, a piston-like valve member reciprocable within the guide for projection into and retraction from said chamber, a packing element applied to the end of the valve member for cooperation with the said seat, the body having'a passageway through which parts of the interior of the body at opposite ends of the guide communicate, an annular ca applied to said annulus, and a screen hel v in place by said cap.
2. A foot valve adapted to be applied to the lower end of a supply pipe for a measuring pump, comprising a body havin a through passageway including a cylindrical chamber, aguide Within said passageway in axial alignment with and constituting an extension of said chamber, an annular valve seat threadably secured to the lower end of said chamber and having a threaded extension thereon, a valve member reciprocable within said guide for projection into and retraction from said chamber and arranged for cooperation with said valve seat, an annular cap screwed onto said threaded 0X- tension and having lugs depending there from and spaced apart whereby to space said valve seat from the surface upon which. said body rests.
In testimony whereof, I hereunto aifix my signature.
