REGULATINGw-VALVE DEVICE.

SPECIFICATION forming part of Letters Patent No. 6 10,938, dated September 20, 1898 Application filed May 10, 1897. Serial No. 635,894. (No model.)

To (0Z5 whom, it may concern:

Be it known that I, JOSEPH H. CHAMP, a citizen of the United States, and a resident of Cleveland, county of Ouyahoga, and State of Ohio, have invented a new and useful Improvement in Regulating-Valve Devices, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings, Figure I represents an elevation of an apparatus, showing my improvement attached thereto and showing a portion of the liquid-chamber broken away to show the float and float-lever. Fig. II represents a vertical longitudinal crosssectional view of the valve-chamber, valveseat, valve-stem nut, and a transverse section of the float-lever chamber. Fig. III represents a detail side elevation of the end of the float-lever chamber. Fig. IV represents a detail perspective of the valve and valve-seat. FigV represents a vertical longitudinal crosssectional view of the same, and Fig. VI a second form of valve.

The device is one of the type of regulating devices which is actuated by the liquid-level in a liquid-chamber, thereby regulating the supply of liquid to said chamber.

To the reservoir A is attached a float-lever chamber A, which is traversed by the floatlever a, on the end of which is attached an ordinary float a. The other end of said lever a is attached, by means of a set-screw o to a valve-stem B, which is suitably journaled in a water-tight manner in the end of the said lever-chamber A.

The valve-chamber O is formed with a suitable flange c, whereby it may be bolted to the side of the chamber A. The said side is formed with a depression a adapted to receive the flange d of the valve-stem nut D, which nut is adapted to receive a threaded portion b, formed on the valve-stem B, said flange (1 being clamped in said depression a by said flange c.

WVhen the float and lever are in theirlowermost position, the end of the stem B is made to be substantially flush with the end of the nut.

The valve-chamber is provided with a removable valve-seat 0, formed with a central bore 0 and having perforations c communicating therewith and with the inlet C through the medium of which bore and perforations communication may be established between said inlet and the outlet G The said valve-seat screws into an opening 0 in the valve-chamber opposite the opening 0 and up against the wall 0 and the end of the seat is preferably capped with a guttapercha or vulcanite ring 0 having a sharp contact edge 0 A guide-pin C is fastened in the center of the valve-seat O and projects some distance beyond the wall 0 The valve-chamber is formed with wall Cflprojecting angularly outward from wall O and forming inlet water-space 0 between such two walls, such water-space a being around the perforations c opposite to the inlet 0 and there communicating by such perforations with said bore 0, the opening 0 being formed so that the valve-seat has screw-thread engagement with said wall 0 and is free from engagement with the valve-chamber between said two walls O and O.

A valve E, preferably of hard rubber or vulcanite, is formed with a central bore e, extending partially through it, and the bored end is formed with a beveled edge 6, adapted to enter the opening 0 of the valve-seat. The said valve is placed upon the guide-pin O and may be reciprocated to and from the seat on said rod. The outlet O communicates with the liquid-chamber by suitable piping, such as the pipe F shown in the draw ings. The float-lever having been properly adjusted on the valve-stem to givethe required height of liquid in the liquid-chamber, the liquid enters through the inlet 0 and by its pressure pushes the valve from its seat and against the end of the valve-stem, enters the outlet, and from thence reaches the liquid-chamber. The float rises and in so doing rotates the valve-stem, which is thereupon moved toward the valve-seat and pushes along with it the valve which it abuts until the said valve reaches its seat and shuts oif the supply of water.

The form of valve shown in Fig. VI is one which I prefer to use in small valves and in which I form the threaded portion 1) of the valve stem with a central bore 19 The small valve E is made of suficient length to fit therein and is provided at its end with a small piece of wire 6 by which, after the valve-seat has been removed from the valvechamber in the same way as with the firstmentioned form of valve, the said small valve may be easily extracted from within the valve-chamber. The end I) of said valve-stem thereby forms the guide for the said valve. This does away with the necessity of providing a valve-guide pin such as C in the other form.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means covered by any one of the following claims be employed.

I therefore particularly point out and distinctly claim as my invention 1. The combination of float-lever chamber A, valve-chamber O fastened to said chamber A, nut D clamped by and between said two chambers, threaded valve-stem B, valve, valve-seat, substantially as set forth.

2. The combination of float-lever chamber A, valve-chamber 0 having flange o, nut D clamped by and between said two chambers, threaded valve-stem B, valve, valve-seat, substantially as set forth.

3. The combination of float-lever chamber A having depression a valve-chamber 0 having flange c fastened to said chamber A, nut D having a part clamped in said depression by flange c, threaded valve-stem B, valve, valve-seat, substantially as set forth.

4. The combination of float-lever chamber A having its side formed with depression a valve-chamber 0 having flange c fastened to said chamber A, nut D having flange d clamped in said depression by said flange 0, threaded valve-stem B, valve-seat C screwthreaded into an opening in said valve-chamber, valve loosely engaging with said valvestem, substantially as set forth.

5. The combination of float-lever chamber A having its side formed with depression as, valve-chamber 0 having flange c bolted to said chamber A, nutD having flange clamped in said depression by said flange c, rotary valve-stem B threaded in said nut, valvechamber 0 having inlet 0 and outlet 0 and intermediate valve-opening c bounded by wall 0 valve-seat C screwed into opening 0 and against said wall 0 and having central inner end bore 0 and peripheral perforations 0 communicating with said bore and with said inlet 0 guide-pin O fastened to the center of said valve-seat and projecting longitudinally through said bore, valve E having central bore 6 in which said guidepin is loosely fitted, said valve having free end engagement with said valve-stem and being smaller than said openings 0 and 0", substantially as set forth.

Signed by me this 27th day of April, 1897.
