FOOT-OPERATED VALVE.

Specification of Letters Patent.

Patented Sept. 26, 1911.

To all whom it may concern:

Be it known that I, VIo'roR D. RnNwIoK, Jr., a citizen of the United States, and residing at Pleasantville, in the county of Atlantic and State of New Jersey, have invented certain new and useful Improvements in Foot-Operated Valves, of which the following is a specification.

This invention relates to improvements 1n foot operated valves and more especially to that class of such devices known as push button valves.

An object of the present invention is the provision of a simple valve construction especially adapted for water serv1ce pipes and readily operable without the aid of the hands of the operator but solely otherwise manipulated.

The present valves are of the self-closing type and while the use of such valves operated by the feet of the operator is known to be used in special instances, such as in surgical hospitals and also included in the wash basin slab for operation by hand, this broad invention is not now claimed; but the present construction is especially designed for providing a foot operated water valve that is simple and easy to manufacture and at the same time readily adaptable for all common uses, such as in connection with the wash basin or sink of the ordinary toilet room or kitchen. Another object is to provide such a valve construction in which all the parts may be easily accessible and by the releasing of a single element the entire valve member and its mechanisms are freely re movable from the valve casing.

While there is herein shown but a single device, it will be understood that the invention is not alone limited thereto but is readily adaptable for the manipulation by a single push button or floor plate of a plurality of valves, such as a separate valve for hot and cold water.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists of the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings forming a part of this application and in which like designating numerals refer to corresponding parts throughout the several views: Figure 1 is a side elevation of the device with a portion thereof shown in longitudinal section. Fig. 2 is a transverse sectional view taken upon line 2-2 of Fig. 1. Fig. 3 is a side e1eva tion of another form of the device partly shown in section. Fig. 4 is a central section thereof taken upon line 4- l, and, Fig. 5 is a plan view of a floor section including the device positioned therein.

Referring in detail to the drawings, the fioor 10 being provided with a mortise opening 11 is illustrated with-the plate member 12 positionedtherein and to the underneath surface of which the valve casing 13 is suspended, the latter being provided with the usual inlet and outlet ports 14: and 15 respectively, by the opposite side plates 16 forming a yoke suspension for said casing, easily removable through said opening.

The casing 13 is centrally provided interiorly thereof with the tapered opening or bore 17 within which communication is had with the bottom thereof by the contracted portion 18 of the inlet and at a point therein and above said opening by a contracted por tion 19 of the outlet. A tapered cylindrical valve plug 20 is ground for closely fitting within the bore 17 and having a hollow chamber 21 therein is aflorded communication with the. outlet through the port 22 in the wall of said chamber. lhe bottom wall of said chamber moreover is provided with an inwardly tapering valve seat 23 which seat is in the form of a port affording communication between the chamber 21 and the space 24 beneath the valve plug and the inlet. A cap 25 being screw-threaded upon the top of the plug 20 provides a stuffing box 26 therebetween. A collar 27 is loosely journaled upon said plug at a point beneath said cap and is screw-threaded within the upper extension 28 of the valve casing in such a manner that the unscrewing upwardly of the collar 27 operates by its contact with the cap 25 to forcibly remove and withdraw the plug from the casing. A copper asbestos lined gasket 28' is interposed between said collar and the annular seat 20' of the plug.

Sockets 29 are provided on opposite sides ,of the valve casing member 13 secured to the plates 16 for the reception of the bottoms of helical springs 30 which, at their tops, are seated within similar sockets 31 provided in the under surface of the actuating plate 32.

valve stem 33 extending centrally through the valve plug terminates at its lower end in a tapered valve 34 adapted to accurately fit the seat 23 while the upper end of the valve stem is secured to the floor plate 32 by set nuts 35 and 36. In any clesirab-le manner, a friction plate 37 may be secured to the floor plate 32, the same being here shown as slidably mounted therein between the opposing flanges 38 thereon, the said member 37 being preferably formed of a substance which is warm to the touch of the individual when desiring to operate the valve for instance by the hand or bare foot. Surrounding the floor plate 32 is provided a finishing plate 39 secured to the plate member 12 by hold-fast devices 40, while four wood screws 40 secure the plate 12 to the floor 10.

In Figs. 3 and 4 a less intricate form of the invention is disclosed and in which the side springs 30 are eliminated while the side plates 16 are secured to the valve casing 13 in substantially an identical manner. The Valve and plug construction as well as the valve stem connection with the floor plate being substantially identical to that above described in connection with. Figs. 1 and 2, it will be unnecessary to further describe the remaining elements with the exception of those which differ in the two constructions.

Further referring to Figs. 3 and 4, it will be noted that the cap 25 is loosely journaled upon the upper end of the valve plug 20 and includes the packing 26 between the said cap and the upper end of the plug. The cap 25 at its lower periphery is provided with an integral upturned flange or collar 42 extending entirely around the cap and adapted to receive therein a helical spring 43. surrounding said cap and inclosing therein a valve stem 33 and the downwardly-projecting portion 44 of the floor plate 32. The upper end of said encircling helical spring is seated within the annular socket 45 on the under face of the floor plate.

The complete operation of the invention will be at once apparent from the above description.

The pressure of the foot upon the covering or top insertion of the floor plate re sults in a downward movement of the valve seat and valve and a consequent unseating of the latter which allows an entrance of the fluid to the valve casing and from which it flows in a manner that will be at once evident. A release of such pressure upon the valve stem allows the resilient means to again reseat the valve shutting'ofl the flow of fluid through the casing.

In this class of devices, it is desirable that of the top of the valve seat while the said,

piston 60 is adapted for reception and free movement therein. The operation of the last described elements is similar to the or dinary dash pot and it will be readily seen C that when the valve and the piston 60 upon the valve stem are lowered for allowing the water to pass from the inlet to the outlet of the valve casing, that water will also be admitted above the piston 60, whereupon when the foot pressure is removed and the valve automatically closes, this water will slowly be forced out downwardly and thus allowing the piston 60 to gradually rise until the valve is entirely seated and the water supply cut off. It might be noted that the piston 60 may be provided with small openings if desired or the chamber within which the same operates might be slightly tapered upwardly to allow the water to be more easily expelled therefrom.

In connection with the water faucets or bibs employed with the ordinary sinks or wash basins, the positioning of the present foot actuating devices therefor may be at any place desired but a most convenient position for the same has been, found to be at a point a few inches within the front line thereof and slightly underneath the same so that the placing of a foot upon either the hot or cold water floor plate or both readily regulates the flow of water as may be desired.

While the forms of the invention herein shown and described are what are believed to be preferable embodiments thereof, it is nevertheless to be understood that changes may be made in the form, proportion and size of the parts thereof and in minor details of construction without departing from the spirit and scope of the invention as set forth in the appended claims.
