FLEDnWA'lER REGU LTR SPECIFICATION forming part of Letters Patent No. 683,630, dated October 1, 1901.

Application filed October 22,1900. Serial No. 38,860. (Noimoflel.)

10 all whom it nir/ty concern:

Beit known that I, HENRY HERMAN WEST- I NGHoosE,a citizen of the United States, resid' ing at Edgewood Park, county of Allegheny, 5 Stute of Pennsylvania, have invented or discovered e certain new and useful Improvement in Feed-WeterReguletors, ofwhich improvement the following is a. specification.

My invention relates to feed-water regulators for boilers, and has for its object to provide an improved form of regulating-valve which will not stick to its seat, but one which will always be free to move under the action of a. ioat or other menusv controlled by the Water-level in the boiler.

Heretofore reguletingl vnlves have been used which were held against their seats by a. continuous pressure .end it wes found that such valves very soon became stuck to their Seats, owing to the friction and accumulation of sediment, so that the valves would not open and close properly under the notion of a. float to regulate the supply of water to the boiler.

Myinventiou consists in en improved form of reguletingwelve so located in n. Writer-pipe connectedto the pump that the suction-stroke of the pump tends to draw the valvefroin its sent nud mee-ns controlled by the water-level in the boiler for moving said velve on its seet or parallel with its seat, whereby the valve will be opened or closed according to the height of the Water in the boiler. By

' this means the valve is loosened from its seat et each stroke of the pump and is thereby balanced, so that there will be no friction or sticking of the velvc; but the saule may be freely operated by the iiout or other means governed by the Water-level in the boiler to open end close the valve.

I have illustrated my improvement in the accompanying ings, in which- Figure l is n diagram showing the boiler, ieedpurnp, supply-tank, .end the various pipe :2, e sectional view showing t ol regulating-volvo, and Fig. El fcai View showing a. modified construction o1 valve adapted to be used as s.

suction-volvo of the pump.

As shown in Fig. l, the Seed-pump l is con-A nected to the supplytenk 2 by the suctioni pipe 3 and to the boiler l by the delivery-pipe 5, these pipes being supplied with the usual check-valves. Thepump maybe operated in any convenient Way, as by a. belt-pulley and crank-shaft, or in case my device is applied to an automobile the pump may be operated from a Wheel or axle of the carriage. Another pipe 9 is connected directly to the pump and leads to the regulating-valve casing 10, from which the outlet or return pipe ll leads to the bottom of the supplytank 2. As a. means for controlling the regulating-valve according to the height of Water inthe boiler I have shown a lient 2l, located in a float-chamber 6, which is connected to the boiler by pipes 7 and 8. The iioat is adapted to rock the shaft 22, which extends outside the chamber and is provided with un arm 23, on one end of which is located the balance-Weight 24, the other end being connected to the erm of the valve by means oi the rod 25. It is obvious in the boiler may be used for operating,r the regulating-valve. v

In the vulve-casing l0, es shown iu Figs: 2 nud il, is located the valve-seat l2, having openings or ports 13 and provided with a. cylindrical extension or bushing which fits within the casing. In the bushing the reguletting-valve Ll is located, which is also provided With ports l5. I have shown the valve lfind valve-seat of conical form, es this gives n tight joint between the valve and its sent at the downstroke of the pump; but it is evideut that the valve might be in the form of zt dat disk or some other form adapted to move on its seat or parallel with its sont to open and close theports therein. 'lhe stem 16 of the regulating-valve il extends out through thc casing and is provided :it its outer end with an arm 17, by which the valve may be rotated. The valve lei is in direct communication with the pump, so that each suction-stroke of the pump tends to drew the vulve owzty from its seat, while et each down wurd stroke the valve is forced against its sont by the water-pres sure.

In Fig. 2 is shown n. light spring 18, which maiy be used to partially counteract the effect of the suction` on the valve and prevent the seine from moving away from its sont; but

that other ineens controlled by the water-level IOO - even when the spring is usodthe volvo will be loosened from its seat at each stroke of the pump, so that it will be balanced es to'pressure and therewill be no friction between thevalve and its sont vto conse the same to stick or vto prevent its free rotation under the sction o' the float.

In Eig! 3 Vl here illustrnted it slightly-modi- Yfied form in'which u. sliding joint 19 is profree o ouin for the essere of water from D b the teck or pipe ll through the ports of thei' valve to the pipe 9, Whether the ports 13 und 15 in the velve und its 'sect happen to be in register or not, und the water will be drawn into the pump. Then et the downward stroke of the pump the Water will be forced into the boiler or beck into the tenir according as the ports in the regulating-waive le are hold closed or open by means of the floot. "lu this wey the regulating-vulve 'xunybense'd as e. sncton-vslveof the pump and thershutfo cock 2O .in the suction-wipe 3 maybe closed,

or seid suction-pipe may be dispensed With altogether.

The 'operation of my device is :is follows: When the Water becomes low in the boiler, the iioot rotates the .vulve ll to close the seme, so that the ports l5 do not register with the ports 13 in the valve-sent. Consequently the pressure et each downward stroke of the' pump forcesrthe vulve le against its sent and prevents any waiter from returning to the tenis' through pipe ll. Then the feed-pump l, which is operating continuously or when. the carriage is running, lrewswater from the Supply either through pipe 3 and its check-valve or through pipo li and the reguloting-vulve and forces it into the boiler through pipe 5. vAs the Water in the boiler rises to a, point nt or above the normal witterlevel the float rotates the vulve le, so as to open the ports through the valve-sect. Then the water from the ypump will be discharged beck into the tank through pipe 1l, and no more writer will enter the boiler n util the wetter-level therein lues lowered sufficiently to allow the liest to close the portsI of the reguloting-val ve. The waiter will then be supplied to the boiler again, as before described.

The Valve. is free to be rotated by the Hout et all times, sinoe'it is loosened from its seat et each suotiowstroke of the pump, und this loosening of the valve from its sont stench stroke of the pump not only balances the valve as to p:essnre,bnt prevents the nocumulation of sediment or corrosion, which would tend to'ceusee. sticking of the valve.

Hoving now described my invention, what l cle-iin as new, and desire to secure by Letters Potent, is-n y l. ln o feed-water regulator for boilers, the combination With :L feed-'pump und a pipe or :t regulating-valve so located in the said pcssngethet the .suction of the pump tends to drew the valve sway from its sent, and means controlled bythe Waiter-level in the boiler for moving seid valve parallel with its sent to open sind close said volvo.
