STEAM-PUMP.

Specification afrLettcrs Patent.

To all whom, may concern Be it known that I, VALTER O. WHEELER, a. citizen of the United States, residing at vllorcesteiy in the county of lVorcester and Commonwealth of Massachusetts,liave -invented a new and useful. improvement in Steainlumps, of which the following is a specification, accompanied by drawings forming-a part of the same, in which- Figure 1 is a sideelevat'ion of a pump invention, and Fig. 2 is a central sectional view on" the broken line Similar' reference characters refer to similar parts in the different figures.

. The object of my present invention is to 'provide an automatic pumping apparatus adapted to maintain an automatic intermittent action by the alternate admission and condensation of steam.

The apparatus present invention is particularly adapted to be used in connection with steam radiators for` the purposeof exhausting the air and water of condensation therefrom, and my invention consists in the construction and arrangement of parts as hereinafter decribed and pointed out in the annexed claims.

^ Referring to the accompanying drawings, 1 denotes a fluid chamber* having an inlet opening 2 connected with va steam radiator, or other chamber which it is desired to eX- haust, and controlled by a valve 3 opening inward to allow a free movement-of air or liquid into the chamber 1, but preventing its return. The fluid chamberlis also pro-A vided with an exhaust ordischarge opening t closed by il valve 5, which` opens outward to allow Ithe; discharge of air or liquid from the Huid'L chamber 1. The fluid chamberV 1 is provided with a cover 6, having a concen# 7 movement of a sleeve 8 having its lower end 9 extending nearly to the bottom of the fluid chamber 1.

Attached to the upper end of the sleeve 8 is a shell 10 inclosing a 11, and provided n '-its ribs or tinsl. Passing outsidev with radial through the bottom '113 of the fluid chamber 1 .is a .steam pipe 14,

connected with some suitable source of steam supplyand normally closed b a valve 15. The steam pipe 14 exten s upwardly through the sleeve 8 into the condensing chamber 411 with its upper end 16 terminating forming the subject of my' to allow the free up and down condensing chamber.

' through rest in the notched bifurcatd ends of a lever 23 provided with a knife edge 9A supported upon a bracketlZ and forming the fulcrum for the lever 23.

Adjustable' on the lever 23 is a counterlweight 26, which is so placed on the lever that it will just counterbalance the shell 10v and hold it in a raised position. 'The lever 23 is connected by a link 27 with the steam valve 15, which is likewise held normally closed by the counterweight Q6. The bushiiig 7 is provided atthe top with a cup shaped recess 28 to contain water for sealing the vertically movable sleeve 8. The sleeve 8 .is also provided with a series of grooves 29, which till with water and pack the joint between the movable sleeve 8 and the bushing 7.

A pipe 30 leads from near the bottom of the condensing chamber 11 to a spout-- 31 which empties into the cup shaped recess.

28, and a pipe 32 leads from near the bot toni of lthe exhaust opening l to the spout 31, said pipes beingv closed by spherical valves 33 and 33a. Between the-shell 10 and spout 31, thepipe 30 is provided with a ltelescopic section 34, which allows for the rising and falling movement of the shell 10 as hereinafter described. The -cup shaped recess 28' is provided with an overflow pipe 35, through which any excess of water supplied through the spout away.

The apparatus is set in operation by removing a plug 36 and filling the Huid chamber with vwat-er until it lifts the valve 5 and escapes through the discharge opening 4, the water lthen standingupon the level indicated by the broken line 37. The end 33 of the lever 23 is then raised b v hand in order toy open the steam valve 15, when steam passing the pipell fills the condensing chamber 11, driving out a'iiyair contained therein through the pipe 30. k'Nhen the condensing chamber '11 has become filled with steam, which may be determined either by a pressure gage or by the emission of steam Patented Jan. 16,1912.

31Yniay be conducted causing the' water contained in the fluid chamber 1 to rise through the annular space between' 'the steam 'pipe-v 14 and the sleeve Sinto the condensing'chamber 11.` As the water descends. inthe `'fluid chamber 1, a

suction is created.' throughthe inlet opening 2, therebyy maintaining a pressure upon the .water in the fluidchamber until4 the water flowing int-o the condensing'chamber has increased the 4weight of the latter in excess of the counterweight 26 when the shell 10 descends; rocking the lever 23 and opening .the steam valve 15, thereby admitting steam to the condensingv chamber 11 which forces the water'. in the condensing chamber back into the fluid chamberl. If only air'hasV been drawn into the 4fluid chamber through the inlet opening 2,1ity will escape through the pipe'32, but if'thex fluid chamber has.

filled f with'water throughv the inlet open- "ing, it will be forced4 through the outlet -opening 4, raising the-valve 5 unt-il the water level 3 is again reached. When the water has been forced from the condensing chamber 11, the latter will. become lightened suztf v condensation of steamagain takes iciently to 'allow' the counterweight 26 to reverse theI action of the lever 23, thereby4 'closing the steam valve 15 and raising the shell l()v to its normal/position, when.; the place and the pumping action is repeated.

Resting upon the bottom of the shell 10 is a cup 39 which incloses the lower end ot' the pipe 30,'and is lraised by the inflowing Water into the chamber 11 until the bottoml ofthe cup is made to close the pipe 30; As. the water continues to rise, it will fill the cup '39 causing it'tofall u on the bottom of the shell 10, but, being lled with wateryit will act as a sealto the pipe 3Q. The pipe 30,

therefore, remains open for the escape of air during the initial entrance of steam, but subsequently becomes v Sealed by means of the cup 39. The pipe 32 has its'- lower. end

inclosed in a similar cup 40, which permits the escape of air past the valve 33 pduring the initial filling yof the fluid chamber -With Water. Afterthe. cups 39 and 4 0 become filled with water, more or less of the'IWater contained therein 4is liable to be .forced through the pipes 30 and 32 j anddelivered by the spout 31 into the cup :28e-thereby maintaining able sleeve 8. y

After the apparatus has 'once been 'put-in` operation, it will continue to work automatically, 1 producing an intermittent suction a water packing'- for the slid-- through the iuletf opening 2 froma radiator,` vor other coiinected cliambei'. into the fluid chamber 1 "and ai discharge therefrom vthrough the discharge opening 4. The Water in rthe fluid chamber 1, when steam is admitted to the condensing chamber 11, Will l be forced upward into the condensing chamber until the combined weiglitof the shell 10V and the Water contained therein is in eX- cess -of the counterweig'ht 26, Whenthe latter will be raised, opening' the steamyalve 15 and allowing the pressure of steam to again force thewater from the condensing chamber 11-b`ack yinto the fluid'chamber l, and. causing any excess of water whichmay have been received in the fluid chamber 1 through'. the 'inlet opening 2 .torbe delivered through 4the discharge opening 4.- .The Water..re

maining-permanently in'the fluid chamber 1, therefore,acts -as a liquid pistonwhich, by its rising' and falling movement, sucks through the inlet opening 2' into the fluid chamber 1 and discharges. the excess. of

water so received through the discharge opening 4.. l
