To all whom it may concern:

Be it known that l, FRED W. Powers, o citizen of the United States, endresident of Chicego, in the county of Cook and State of illhnois, have invented certain new and useful lro rovements in a Damper Re ulator for Liqui -l nel Burners, ofwhich lowing'is o specification.

My invention relates to devices for use in connection with heaters equipped with liquid incl burners and particularly to a novel orrangernent by which fuel is conserveo.

ilt is customer in the operation of liquid fuel homers in nenters to provide for tree escape of the waste gases through c stock and to utilize an opening such as that commonl controlled h the ash pit damper for supp pine the requisite air for proper comhnstion the liquid fuel. it is aiso'cnss tomer to provice tor intermittent operation of the horn-er antler the control oi a thermostat, Consequently sharing the periotl when the is not in operetion there is a constont o1? coltl sir through the heater where heat is nhsorherl onrl lost.

An object of this invention is to provide means to prevent any such loss of l accomplish the decimal result the folheat to hy the neo or? simple roeohonisro enel without interrering with the normol operation or he i i s .s

corner,

The invention will more renelily nreler stood by reference to the accompanying drewii r3, which:

Figure l is e View portly oliogrorornotie in character illnstroting enemplifieetion of my invention, end i Figure is an enlarge-oi elevation or e do toil or the clemper controlling epporetuei lln the showings heats/rot conventionel form is indieeterl ot lll, e liqnitl inel hiirnerll projecting thereinto, A motor 12 serves to opernte two pumps 18, is, the former fie livering incl encl the his r sir under prescore to the homer hp moons of pipes l5, l8, res oectirely.

'ne is provision with the nsnol srnohe pipe or we to gee ontlet ll, which comronnicetes with e stock 18 seal on ssh pit damper 19. An erm 2U, connectecl to the olamper, is on egetl by is link 21, anti on arm 22, for t e purpose of? swingih g the rlemper to on open or clwerl osition, The

22, se host shown in ig, 2, is inlernnierl 2% on lorochet tormerl so to port motor for snpplyin of o casing 24, rigidly secured in a desired location adjacent to the damper. Within the casing is a bellows 25, the movable well of which engages the arm 22 by means of a projection 26. A sprin 27 tends to resist the expansion of the he lows and serves to more the arm to a retracteol position when the force exerted by the bellows is redocetl The interior of the bellows is in communication with the air pressure developed loy the pump 13, by means of a pipe 28, connected y e T to the pipe 16. 1 The operation is as follows;

When the motor 12 is in o oration, fuel and air under to the burner, t' e air pressure is exerted on the bellows 25, causing the arm 22 to oscillate end to swin the dam erinto the rlotteol line position or lg. 11 en, however, the motor is stop eel, by thermostatic action or otherwise, an no more fuel is losing on to the burner, the press ire within the hollows will he reduced, thereby permitting the ressure are'heing cleliverefi spring; to return the orm to the full line position in which position the damper occn pies the full line position or flip", 1, upon interruption of the burner, the flow of err throooh the hector is stop eel end no hoot-will he corrieol out throng the stools.

While I here shown the dompenopereting hollows es connected to the eir=pressore o, it is obvious thet e similor result might e secnrerl o3! connecting it to the tool supply pipe, Also the clernper employee; ror securing the desired result might he olecerl in the smoke pipe instead oi the os pit These anol other moclificntions ere contern pletesl in the oppenelecl cloims.
