J. J. LAWLER. EQUALIZING VALVE FOR WATER.
APPLIOATION FILED OUT. so, 1911.
INVENTOR James ilawler BY I a r ATTORNEY WITNESSES:
COLUMBIA PMNBORAPH CD ASHINGTON D c UNITED STATES PATENT OFFICE.
JAMESJ. LAWLER, 0F PELHAM, NEW YORK.
EQUALI'ZING-VALVE FOR WATER.
To all whom it. may concern Be it known that I, J Arms J LAWLER, a,
- and State of New- York, have invented a certain new and useful Equalizing-Valve for ater, of which the following is a speci-- fication.
My invention relates to eqrta'lizingvalves used on services where hot and, cold water are combined and delivered ata predetermined'temperature to any desired point,the object being to produce such a device from which the active parts can be removed, examined, repaired or replaced without disconnecting from the service pipes.
A further object is to construct adevice in which a. double crownvalve controls two ports simultaneously in each section, that-is, onthe-hot and on the cold water service.
Anotherobject is to produce a valve which will control the inlet supply without producing a water hammer, and be operative in any position.
The accompanying drawings illustrate the preferred embodiment of the invention, but it is understood that: changes, variations and modifications can be resorted to which come within the claim hereunto appended.
In the drawings, wherein like reference characters denote corresponding partsinthe several views, Figure 1 is a center sectional view, the active parts being in elevation and partly broken away, the arrow heads indicating the direction of the water flow. Fig. 2 is a bottom view of Fig. 1. Fig. 3 is a side view of one-half of the valve body, connected up, the valve seats and lower or diaphragm end being broken away and shown in center section; the active or working parts are removed. Fig. l is a section view on line wm of Fig. 3 and Fig. 5 is the working part or valve proper, shown complete, and removed from the valve body.
The valve body is composed of a casting having two sections or chambers, 2, 3, an inlet, 2*, and an outlet, 2*, for cold water and an inlet, 3, and an outlet, 3 for hot water, the inlets and outlets all being threaded to receive the service pipes, 10. A web, 4, having a forked pendant, 4 is cast integral with the two sections mentioned.
4 is a stiffening rib on each side of the web.
Centrally disposed in the sections are chambers 5, (3 respectively, which extend Specification of Letterslatent.

horizontally to and beyondthe vertical cen* ters of the sections, said chambers also. being-a, part of the valvebody casting. The chambers are provided with two central openings, 5, 5 and 6, 6 respectively in the vertical centers of the sections, the openings being ground true to size. The lower ends 7, 7 respectively of the body are threaded to receive nuts 8-, 8 respectively which fasten the rubber diaphragms 9, 9 respectively, in place, said nuts being provided with central openings 8 8 respectively for the purpose hereinafter specified. The forked pendant 4' is-pierced with a hole for abolt 11, upon which a lever 12 fulcrums.
The valves and stemsin both sections are exactly alike, therefore I will describe the construction of only one. It consists. of a stem, 13, having a crown valve, 14, near its upper end. and another crown valve, 15, some distance farther down, this distance being such that when the valve is in its lowest position, (as shown at the inner chamber in.
Fig. 1,) the tops or disks of both valves will be on a line with the tops of both openings in the innerchamber and the supply of water to that section will be completely closed ofi. A series ofv fingers, 16,-forming the crown extend vertically from the lower surface of each disk, and being turned and ground true on the periphery act as guides, the water passing into the interior of said chamber, 5, see Fig. 1.
An annular flange, 17 at the lower end of the stem engages the rubber diaphragm, 9, the threaded part, 13, of the stem screwing into a plunger, 19, and holding said diaphragm in position, said plunger sliding in the central opening of the nut, 8, 8 the rounded end resting upon the lever, 12, as shown.
The operation is as follows :When the device is connected to both the hot and cold water services, the valves are inserted and the nuts screwed on the lower ends, whereby the diaphragms and valves are held in an operative position; the lever is placed into position in the fork, and the water to each service turned on by independent valvesnot shown,the quantity of water supplied to each service being regulated or fixed by said latter valves, which causes each crown valve to assume a position depending on the pressure against each diaphragm. If any water is drawn off along the line from either service, or if the balance is changed between the two sources of water supply, such difference immediately actuates one or the other of the diaphragms which, owing to its operative position affects the lever in either direction, said lever in turn operating the plunger on the valve stem whereby the valves control the openings in the inner chambers. These inner chambers have two ports or openings so that the water passes downward through the lower openings and upward and outward through the upper openings, both of said crown valves acting simultaneously, or in other words, a movement of the lever in either direction operates four ports at one time. The absence of a disk or puppet valve seat, and the fact that the valves are connected to a diaphragm, prevents any possible water hammer in the pipes, which defect, besides being a strain on the pipes causes annoyance and noise, very serious in hospitals, and other places where quiet is required. By using the sliding crown valves, constructed as described, the shutting oil? or turning on of the water is gradual and no possible sudden blow or check in the flow of water can cause it to hammer.
In case of repairs, the lever is removed, the nut unscrewed trom the bottom, and the entire working part-s of the valve can be removed and replaced without disconnecting any pipes or disturbing the body of the device.
Both plungers rest on the lever at all times so that there is no lost motion, the construction of the device being such that it will act in any position in which it may be set. The lever being in sight, indicates the position of the valves. Such being my invention, what I claim 1s- An equalizing valve comprising a bodyportion having two parallel transverse chambers cast integral therewith, each chamber being provided with an inner chamber having two outlet ports, a member in each transverse chamber comprising a guided valve in each port, said members operating parallel to each other, a diaphragm detachably-connected to each member, a plunger connected to each of said members and extending out wardly from the body portion, means for holding the diaphragnis on the lower ends of the transverse chambers, means for controlling said plungers so that they may be moved in opposite directions to each other, said last-named means being externally positioned upon the body portion, each transverse chamber having a terminal outlet alining with its respective plunger and also having an inlet entering between the two ports of its inner chamber, the said two inlets directed toward each other.
Signed at New York city in the county and State of New York this 15th. day of October A. D. 1911.
