This invention is directed to the provision ment of my invention in the accompanying drawing, which illustrates diagrammatically the apparatus employedv Referring to this drawing, 1 indicates the "stowage-tunic lI1.Wl1lCl1 lS stored the water forfwashiug and filling the boilers of the locoi'notii'es. .i-it, one end of this tank is a heater '2 having therein a plurality of trays 3, and cold water is admitted to the top of this heater through a pipe 4, this W-Ler fulliug lowu over the trays 3 While steam is passing upwardly through the heater, so that the temperature of the ater is raised; by this steam. Aiterpossing over the trays, the Water clrops into a chamber formed by Walls 5 and 6 mounted Within the tank 1, and passes from the-bottom oi? this chain her into the bottom of the storage-tank 1. At the other one of the tank l, is o blowofl chamber '7 formed by walls in and. 9, the former mounted Within the tank: 1 ncl the letter constituting" the curl Willi of the tank. T0 the top of this chamber 2? is connected :1 blowofi' pipe 10, having or chcclcvulre ll therein and nieans are provioeii for making coi'ineetiou between the pipe 30 the boil--v ers oi the locomotives to be blown oil.

in the side or the cliuunher 7 is an opening leading to o cluunoer '12 having it suitable use in boilers and heating apparatus.

The invention is directed particularly to the provision of a heating apparatus for use in supplying 'u'ziter to the boilers oi"; locomotives including}; fecal-voter for the boilers of the locomotives and water for Washing; such boilers, the steam discharged from o lmiler when the hitter is to be cleaned and refilled being utilized for heating the WMQL which is subsequently to be used asteecl- Writer for the boiler.

The object of the invention is to provide on improved form of heating apparatus, which reliable, efiicient and economical in operation and which may be constructed at cciuperatirely low cost.

in uccorduuee with the invention, a tank is employed in which is stored. the heated water which may he used to: Washing and filling the boilers of locomotives anti steam disc-liar ed from the boilers of the locomotives icarried into this tank ind through the waiter therein so as to impart its heat to The water Wlilll'lli the tank is norn'uilly insintuinetl at a substantially uni- Jorrn temperature, and the means for accomplishingg this includes a heater and o cir-- culziti r system by which water drawn water rises to a. predetermined height Within. the chamber 'T it will operate the float-valve 13 so as to perInit the Water to-tlow oil? to Waste through a pipe 14. A battle-piste 15 is secured to the side oi? the chamber 7 over the opening lemiing to the float-valve 13, and this bathe-plate extends downwardly odjiicent to the bottom of the chamber 7 so that the Water which passes out through the float-valve 13 is drawn from the bottom of the chamber 7. By reason of the provision of the hatiie'plote 15, the Waiter blown off fro'in'the locomotive through the pip 10 set t-les Within the clunnher 7 unt l ample time is allowed for the liberation of the steam ehter wherein its temperature is raised, and then curriecl hock tothe. storage-tank i lie pump for this misting system is controlled eutonieticzil in response to changes of tern pernturc the Water in the tank; whcn the tcu'iperotuw of the storetl 'Watcr tails heiow tl Ellt Wllii'll s desired, the circulatingpump contained in the water.

[it thol'ower end of 'u'ci'cruhl :cuiploy a. supply of live steam Z this possegewoy connect1on is mode to a which is hmiutl =1: politically under prerle- 3 pipe l9 extending along the side of the stortcrmiuml (A Iona ondother devices as l age-tank 1. near the bottom of" the hittoix lieiei'uiiftw (he ih tl. i This pipe 19 is provided at a lureiity of l have lllthll lit'tl the preferred emb-Odig )OlIli.S along its lengthwith connections 20 fiozitwulve 1S3 ,thei'ein, such that when the for carrying the steam from the pipe 19 into the storage-tank 1. The steam rises through the water within the storage-tank and in doing so imparts its heat to the water, after which such steam as is not condensed passes over the wall 6 into the heater 2, wherein it rises through the series of trays 3 and passes out attheoutlet-opening 21. In order to replenish the supply of water in the storage-tank 1, a float 22 is provided within the tank, connected by suitable levers with a valve 23 in-the cold water-supply pipe, so that when a predetermined amount of water is drawn from tank 1 the floatvalve will be operated to open valve 23 more or less and thus admit water through pipe 4 to the heater 2.

In order to insure the maintenance of a predetermined temperature within thetank 1, a circulating system is provided, by which water is circulated from the bottom of tank 1 through the heater 2 and back into the tank, and this circulating system is automatically controlled, so that it will be brought into operation whenever the temthat desired. This circulating system includes a pump 24 connected by pipe 25 to the bottom of the tank 1 and by pipe 26 with the top of the heater 2. Steam for operating the circulating pump 24 is admitted to the pumpthrough a pipe 27, and the admission of this steamisautomatically controlled by a valve 28 .operatedby a thermostat 29 which is mounted upon theside of the tank 1 and is responsive to changes of temperature of the water within that tank. When the temperature of the water in tank 1 falls, the thermostat operates to open the valve 28 and thus admit more steam to the pump 24, and the latter causes circulation of the .water from tank 1 through the heater 2.

When the temperature of the waterin tank 1 has been raised to that desired, the thermostat will operate to more valve 28 toward the closed position, but preferably the valve will not'be entirely closed but will permit of the supply of enough steam to pump 2-l to keep the pump operating slowly.

It may be that at times the steam rising through the water in tank 1 and passing up through the heater 2 would not be sufiicient to maintain the temperature desired for the water within tank 1, and I have therefore provideda live-steam connection, whereby steam from. a source .of supply other than the locomotive which is blown oil through pipe 10 may be automatically admitted to the chamber 7 and from that chamber tovthe tank ,1 and heater 2. This live-steam connection is shown at 30 and .has. a diaphragm-valve 31 connected therein. This diaphragm-valve is connected by the pipe 32 to the pipe 33, which connects the thermostat 29 with the valve 28, and it the temperature of the water in tank 1 is not raised to the desired pointby the heater 2, employing the steam blown off from the locomotive, the further operation of the thermostat 29 will cause the diaphragmvalve 31 to open and admit, live-steam through the pipe 30 to the chamber 7 and from the latter to the tank 1 and heater 2.

WVater for washing the locomotiveboilers is pumped from the-tank 1 through a pipe 34 connected to the upper portion of the tank 1 by a pump 35 forcing the water through "a pipe 36 to the locomotive.

Between the wall. 5 within the tank 1 and the end wall of the tank, is a second heater 37 having trays 38 therein. ater is supplied to the top of this heater by a pipe 39 connecting with the cold-water-supply pipe 4, and in. this pipe is a valve 40 operated by a float tl within the heater 37.-

Steam is led to the trays 38 within the heater 37 through a pipe 42 connected with the exhaust of stationary steam-engines withinthe plant and any other apparatus exhausting steam. This steam passes upwardly around the trays 38 so as toheat the] water falling over these trays, and if more steam is entering through the pipe a2 than is required for heating the water within the heater 37 this excess of steam passes through an opening in the'wall 5and upwardly about the trays 3 of the heater 2 and then out through the pipe 21. The water collecting at the bottom of the heater 37 may be used for filling the boilers of the stationary en- 'gines about the plant, this water being drawn off by a pump 43. The water-chamberwithin the heater 37 and the tank 1 are provided with suitable drain-cocks In employing the apparatus above described, the method of operation may be substantially as follows: The water within tank 1 is normally maintained at a temperature such that it is suitable for use as wash-' ing water in cleaning the boilers of locomotives. punped through the pipe 34 by the pump The maintenance of this temperature is eiiected by the circulation of the water from the tank 1 through the heater 2 and then back to the tank, the water being heated within the heater by steamrising from the water in tank 1 and by the excess of steam entering through pipe 42 over that required in the heater 37. Cold water is supplied to the tank 1 through the heater by' the pipe 4 when the valve 23 in that pipe is opened by the float 22. This circulation of the water For this purpose, the water is from tank 1 through the heater 2 is automatically effected by the pump 24 controlled by the thermostat 29, the'pump being startto 'operate the valve 28. It: the temperature predetermined amount, this is due to the fact that the steam passing through the heater 2 has been insulticient to impart the required heat to the water which is being circulated by the pump 2 and the ther-- mostat 29 then operates the diaphragmvalve 31 so as to admit liresteam through the pipe 30 to the chamber 7, and this steam passing through the 'water in tank 1 and.

upwardly through the heater quickly brings the Water in the. tank 1 up to the required temperature. ll hen. a boiler is to be blown off, suitable connection is made to the pipe l0,and when the water and the steam in the boiler are delivered into the chamber 7,

thewater flows out from the bottom of the chamber to V2] ste, but the steam rising from the Water is carried into tank 1, in which it passes upwardly through the water therein to the beater r Having described my intention, what l claim as new therein and desire to secure by Letters Patent ol the United States is:
