Z'ea whom z5 may omwerm l lie it known that We, HENRY l "ZO HOUSE and HENRY' ALONZO HOUSE, .l eebanical engineers, both citizens OE the 'United States 5 of Ainerloa and both teinporai 'esiding at Teddlngton, county of Surrey, england, but usually of Bridgeport, county of lairlield, and State of Conneetieut, United States of America, have invented a certain ne .r improved Feed llater am. @las liep@ i .egnlatoig of which the following is a speci tion. ln tubnlona steam. boilers or oerators in which the quantity of Water oer. i, Aed in them is comparatively small it is extremely important to main etant as i .in the levelof the water as con e and to reduce or extinguish the level. falls below a For this purpose we employ an 1 d water and gas supply regulaid shown in. Figures l, 2, 3 and i llie Hineaed drawings, in which verlieal section taken on line il va sectional elevation e of Fig. 1;*lfig. 8 a sectional pian lalroi'l. en line 3-3 of Fig. l, and Fig. il shoe ille same apparatus to a smaller scale to a tubnlous boiler or generator v vessel ifi, ei any suitable shape is pro- @ed al; the Water level of the Jr. '.lhe upper end of this ves- 1 eoted a pipe with the steam oe U ei the boiler and the-lower end therea pipe il? with the lowelf'ert of the water'sease lil so the there is an equilibrium of isere in, the vessel ll and in the boiler,

and the 'Water stands at the same level in beth. i lloat 5 in the vessel R rises and falls wil. The water oontained therein and Operates by means ota lever 'l and links T T2, a slide valve U ,lilted to slide between guides L pperiart of the vessel R.' This v eros two parte V V the upperof l y a pipe V2 to any suitable leed pump (not shown in the de not @Online ourselves to i 45 sell? any p" A .oler p nip) andthe lower of which V leal i pipe Vd to a regulaling plunger orpistoo iw wirlringin aeylinderl/iagainst Vgerl or pist-en sereine. indizi. einem@ n.

This plunger or piston operates the regulating tap or valve lli. ef the aas burners by which the boiler' is heated. ll' noer the water level falls, the 5 5 float S falls also, and lowers the slide Valve .U,j uncovering the upper part V; steam then passes by pipe V2 from the vessel R to the feed pomp and` sets it in niotioin and feed Water is introduced into the boiler or genera- 6o ter; but if from any cause the feed pump fails testari., or fails to force Water into the boiler, and the Water level falls still lower, the float S falls withv it and the valve U is lowered still farther whereby the lower port V' is iineov- 6 5 ered and steam passes by the pipe V3 to the Acylinder W', acts upon the plunger or piston W therein and in'oves it forward against the Opposing spriugW2 or weigl1t and causes it Y to shut the gas tap or valve X thereby cutting 7o Off more or less completely gas from the burners and preventingthe generation of an y more steam vuntil the defect has been reine` died. When the water level rises again the float S rises also carrying with it the slide 75 valve U which closes the lower steam port V' shutting off steam from t-he aforesaid cylinder 'W' the plunger or pistn in which is then pressed back by its spring or weight and opens the gas valve X allowing the evapora- So tion to proceed. The steam behind the'pluir ger or piston 'W s allowed to escape, when the port V is closed,through a weeping hole 'or properly adjusted tap V, On the other hand if the water level rises too high the float S5 S rises still higher taking with it the slide ValvegU Wliieh then closes the upper steam port V, thereby stopping the feed pump and consequently the further delivery oi food Water to the boiler. The port through the 9o slide valve U corresponding to the port V is made wider than the port through the Valve U corresponding to the port V in order that the pori Vmay romain Open however 10W the float may descend in the vessel ll, and until 9 5 tliexproper level of Water has been restored in tbesaid vessel. '.lle `lloat S may be guided in its op and down movements by the pivoted arms Y or otherwise, and more or less of its weight may be counterbalaneed if required by a spring S.

We clai'ml The new or improved apparatus for maintaining the level of the water in boilers or 'generators and for regulating the supply ofl gas for heating the same which consists of a -closed chamber connected with the boiler or generator, two steam ports, one leading to a self starting feed pump, and the othei` to an apparatus for regulating the supply of gas to the gas burners in the furnace of the b'oiler 1 or generator, a slide valve governing the said two steam ports and a iioat for actuating the 15 said slide valve, combined,arranged and operating substantially as hereinbefore described.

In witness whereof we have hereunto set vour hands in presence of two witnesses.
