To (21 5 'wiwm'it'may concern:

lie it known that 1, (IEORGE H. GinsoN, a

citizen of' the United States, residing at Moi'itclair, count -of Essex, and State of New Jersey, have invented certainnew and useful Improvements in Apparatus for Heating \Vater, of which the-following'is a specification.

This invention relates to apparatus for h ating water and is directed particularly lo the provision of apparatus of this character adapted for use in round-houses and similar structures for supplying water for filling and washing the boilers of loconiotires.

The objectof the invention is to provide an apparatus for this use which is reliable and eili'cient in operation, which is economical in that it utilizes the heat in the blowofl" of the locomotive, which can be manu-.

factured and installed at comparatively small expense and wh ch 1S convenient to use."

tire boilers it is highly desirable to save the heat in theblow-otf'jsince in this way a heat containedin tlie-blow-olf-, or a portion thereof, to the water which is to be utilized lli either or both washing and lilling.

The blow-off of the locomotive consists of both steaniand hot w ter, but when a locomotive boiler requires ashing and filling the water in the lOCQIliOtlVG is usually so impure that it is iiiadvirible-t'o return it along with otherwater to he boiler. The can well be futilized and water suppliedtoa 'boilerlin washing and filling the sairie. If the hlhw-oll of a'locoinotive be separated into the steam and water, the steam utilized and the water thrown away, an amount of heat units will be wasted equivalent to the amount neces sary. to raise the blow-oft water from the "temperature-of the supply water to 212flF.

' itl jsuppl water at 60" this will amount to a dill'ereiice in temperature of 1.52".

. lire/present invention involves the 'provision ofa 'iparatus lor' utilizing the heat in.

the blow oll for heating either or both washing and filling water without directly employing the water or the blow-oil, but oh V taining from the 'blowcil more of.the l 'ea't, '1

In emptying, washing and-filling locomofroin the 'blowsOfi irate A v been greatly :rduced 1 n temperature and units therein than is represented by the lz-low-oli' steam or liyjhe ifl'erence between the temperature of. tlie .,b low-off and 212 F. The water of the blow-off is allowed torun to waste but only after its temperature has been reduced far below-that at which-it liberates steam under atmospheric pressure and. the heat obtained in so reducing the temperature of thelilow-olf water is trans ferred to the water to be'lieated. The operation is therefore farinore economical than i one in which the steam and water of the blow-off are separated and thewater at approximately 219, degrees "thrown away, for, i

supply water, so as to lieatthe latter to the temperaturedesired for washing and filling water. This jet' condenser is connected directly to the boiler of a locomotive which is to be emptied or to a suitable closed i'eceptacle into which the cntirefiuidrontentsof a locomotive boiler are emptied, and inthe operation of the apparatus avacuum -is from the blow-olf-is cari'iedand mixedwith 7 being thrown 7 formed in the condenser as is-usual int he operatioiiot such apparatus whiclraidsiii drawing the steam into the condenser. .By reason of the formation of a vacuum in the condenser, the latterreceives not only the steam which was present as such in the locomotive boiler at the time of beginning the blow-off operation but 'it also draws additional stcain'frorn thehot' water in the locomotive boiler until the fteiiiperature of that water has been reduced far belowa f temperature at whichtsteam is liberated under normal conditions, the temperature of the blow-off water beiiigreduced during this operation from '212 .-de'grees to a. temperatu re substantially} lower, depend ng upon the degree oiyacuuin' orniediin i'thef condenser. The ope a t ued thus until, due totthe e traction-of heat that Water --lias n only be eontiiie ice. I

' denser may be carried to a tank or heater and water may be, drawn therefrom for either or both washing and filling purposes, the Water for Washing in that case being mixed with cold water so that it will be at the temperature desired for washing; or if' desired, two tanks or heaters may be arranged to be supplied with water flowing from the condenser, one of these tanks to contain washing water and the other filling water. In-either case automatic controlling devices may be employed whereby the water admitted to the heaters or tanks Will be! at substantially the desired temperature.

The principles of my. invention may be employed in various forms of apparatus.

I have illustrated in the accompanying drawings two forms in which the invention may be practised, these two being showmin Figures l and 2 dia raminatically. 1

Referring first to ig. 1, a blow-ofi pipe is indicated at 1 arranged for connection with a-boiler of a locomotive 2 which is to be emptied. The connection to the boiler may be elfected in any suitable manner as by means of a flexible hose 3, this hose connecting with the upper portion of the boiler,

as forinstance the steam dome or safety;

valve connection, so that when the passage through the pipe 1 is'opened, as by means" of the manually operated valve f1, steam from the boiler will pass through the pipe. Pipe 1 'may extend completely around a round-house so that connection can be made to it from any one ofthe locomotives therein. The other end of pipe 1 is connected to a jet condenser 5 so that the steam passing through the pipe will flow into the'condenser. Condenser 5 is also supplied with cold water from a, pipe 6. The condenser is of the usual or any suitable construction so arranged that steam and water entering the condenser through the pipes 1 and 6 will become mingled, the water heated by the steam and the steam condensed. The water thus heated flows from the condenser through the tail-pipe 7 provided with a manually operated valve 8. Means are provided for receiving the water flowing from the condenserand also suitable con trolling devices whereby the temperature of this water will be regulated. as hereinafter described.

l-Vhcn a locomotive boileris connected to the condenser 5 by meansigof the pipe 1 and the pas mgtuthrough the pipe opened, steam will flow from the, boiler into the condi-nscr where it will beconlh mingled with the water entering the condenser through the pipe 6 and lhetemperature of the water will be raised. the water lloviiing out. through the tail-pipe. During the operation of the condenser a vacuum is formed therein due to the rapid condensation of the steam and tliisyacuum assists in drawing the "steam from the boiler into the condenser. As the steam 'gwlu'chwas present as such-in the boiler at theftime the connection to theoon denser wadopened passes into the condenser, steamwvillbe' drawn oil from the hot water inthe boiler by. reason of the reduction of the pressure, and because of the presence of the flvacuum. in, the condenser 5, operation in this manner willc'ontinue until the temperathe heat units in the ori inal blow-off and the heat units remaining in the blow-off water when, it is allowed to run to waste. Furtherniore, it will be noted that the heating ofthe water which is to be afterward utilized in the boiler is accomplished without mingling with that water the impure water removedfrom the boiler. f In Fig. 1 the tailpipe 7 is shown as por- '-vided,w1tlr two brarlch pipes 9 and 10, the former leading to a reservoir 11.for filling water and the latterleading to a reservoir 12 forwa'shing water. The pipes 9 and 10 are provided with manually operated valves 13 and 14 respectively. In the apparatus illustrated, the reservoir 11 consists of a feed-water heater provided with trays 15 over which the water admitted by pipe 13 flows and a steam inlet 16 for carryingto the heaterll exhaust steam from stationary engines and similar devices to additionally heat the water entering the heater. An Oll separator 17 is provided in the steam pipe 16 and a trap 18 as is usual in feed-water heaters of this type. Projecting into the tail-pipe Tis a thermometer 19 to indicate the temperature of the water passing therethrough and a thermostat 20. This thermostat 20 forms part of a controlling system whereby the temperature of the water lion-- ing from the condenser is regulated' The thermostat 20 operates in any suitable manner, as through the link 21. to position the movable member 2'2 of a master-valve 23.

In the steam pipe 1 is a valve 24 automatically actuated by a piston movable in a cylinder 25. This cylinder is'supplied at one and with water through the pipe 26, the entrance into this pipe being controlled by the thermostatically operated master-valve 23. The valve 23 is also connected by a pipe 27 with cylinders .28 and 29 for operating valves 30 and 31 in the pipes 9 and 10 re spectively, the connections to the cylinders 28 and 29 being at opposite ends thereof so that the admission of water under pressure to pipe 27 tends to close valve 30 and open valve 31. The cyiinders 2B and 29 have springs therein engaging the pistons which operate the movable members of the valves 30 and 31 for moving those pistons in the directions opposite to those in which they are moved by water admitted through pi e 27. The master-valve 23 is also connected y pipe 32 to a cylinder 33 for operating valve 31 in the water pipe (5 so as to move that valve to the closed position as indicated in the drawing; a spring may be arranged in cylinder 33 to more the valve to the open position. lipe 3'2 is also connected by pipe 1&5 to the cylinder L) at the end of that cylinder opposite that to which tnc pipe 26 cormeried so that water admitted to cylinder 2:") through pipe 35 will tend to close valve and this closing movement may be assisted by a. spring in cylinder '35.. W'atcr under pressure is admitted to the cylinder of the mastcr-valve 23 through a pipe 36. Valve 24 in the steam pipe 1 may be so arranged that when moved the maximum dis t: t: by the spring in the cylinder 25 or by a nr admitted through pipe 35. or both. it ll not entirely close the passageway 01. steam through pipe 1. The operation of this controlling mechanism will now be described.

When the operation of heating Water in condenser 5 with the blow-oil steam is commenced. the steam is at its highest temperature and therefore need be admitted to the condenser at the lowest rate. The valve 24 is therefore almost closed and the valve 34 in the Water pipe (5 is wide open. \Vater and steam are admitted through pipes 6 and 1 respectively by opening the manually operated valves 37 and 4 so that steam and water flow into the condenser 5. the water becomes heated and the steam condensed and hot water flows out through pipe 7. This hot water acts upon the thermostat '20 which operates the movable member 22 of the master-valve :23 to an extent correspond ing to the temperature of the tail-water flowing out through pipe 7. When beginning the operation he valve 2-30 is opened and the who 3i closed so the water flowing from the condenser passes through pipe 9 to the heater and reservoir llv This water is to be used as filling water and'therefore ture of the water flowing from the condenser to the desired point. Operation will continue in this why with the thermostat regulating the amount of steam admitted to the condenser so as to keep the temperature of the water flowing from the condenser sub stantially uniform until valve 24 has been opened to its full extent. From this point on the temperature of the water flowing from the condenser will fall as the temperature of the steam admitted falls, until a point is reached at which it will be desired to discontinue the sup )lying of water to the reservoir 11, due to the comparatively low temperature of that water. W hen such point has been reached the thermostat 20 will have moved the movable member of the valve. 23 to such point that water will be admitted from pipe 36- through pipe 27 to the cylinders 28 and 29 at opposite ends of the latter and this will result in the closing of valve 30 and the opening of valve 31. The water flowing from the con denser will then pass through pipe 10 to the reservoir 12 for Washing water and the operation in this way will continue with the temperature of the water supplied to reservoir 12 falling steadily as the temperature of the steam passing into the condenser 5 falls. The temperature desired for the washing water in tank 12 is about 12-0 degrees and therefore the operation will be continued until that temperature of the water in tank 12 has been reached whereupon the operation of the mechanism will beautomotieaily discontinued. by shutting oil the sup 1y of Water and steam to the condenser. 'l iis is effected by the thernmstat '20 when the ten'iperature of the water in pipe 7 falls to a predetermined point by causing the valve. 23 to admit water under pressure from pipe 36 through pipe 32 to the cylinders 33 and 25 in such manner that the valves 34 and 24 are moved to the closed position. The manually operated valves 3' and 4 are then closed. It will thus be seen that automatic operation is secured whereby water is heated in the condenser to the temperature desired for filling water and is carried to the reservoir for filling water as long as steam is available for heating; wate to this temperature. whereupon the conieec tions are so changed that the heated water is diverted into the tank for washin water and that at the end of the operation the connections to the condenser are automati cally closed.

Fig. 2 shows an apparatus similar to that illustrated in Fig. 1 in that a jet condenser is employed for heating the water but differing in that but a single reservoir is employed for the heated water and in that an intermediate rcceptacle is employed for receiving the fluid contents of the-locomotive boiler efore the steam thercofi is carried to the condenser. Rcfcrring to this figure, 38 indirates a hamber in tho form of a steam separator which is adapted to be connected by pi g 39 to the bimv-oil cock of u locomotive. A pipe 1 connects this chamber 38 to the condenser 5, The pipe 7 leads from the condense-r ton fec l-wnter heater and res ervoir ll fillll the thcri'uoslat projects into this pipe and controls the operation of n masterwclv: adapted to regulate the flow of steam through pipe l by controlling the operation of valve :31 in abut pipe as de- SCIll'lQd in connection with log. 1. Filling Water drawn F? m the reservoir 11 through a pipe 4 l is: in the apparatus illustrated in 1* lg. I out to provide washing Watel, the hot water 1;. the reservoir 1]. is drawn off and mixcd with a suitable quan titrof cold Water. For this purpose a pipe ll is shown connected to the reservoir 11 and lending to one cylinder 42 of a pum The other cylinder 'l-rl of the pump has a co d water pipe 4 E councrlcd thereto. The pipes 45 and if leading ircrn the cylinders 42 and l3 res crrively are connected us shown, so that the water missing through them becomes mined and the temperature of the hot water rcduccd. ln orilrr to pcrmit of regulating the temperature of this mixture of hot and cold water asilcsircd for washing the locomotive boilers, a luv-puss 47 around the cylinder 43 is pro ided and a throttle valve 48 is inserted in this bypass so that more or less of the water passing through cylinder 43 may ho allowed to return from the discharge end to the suction end as may be necessary. The pistons in the cylim'lers 42 and 43 are opc-rz'ltcd togcthcfns by mounting'theni on the piston rod of :1 piston moving in a steam cylinder 42*. if desired a wiring chamber 50 may he insertcd in the pipc St for carrying the washing water to insure oropcr mixing of the hot and cold, water gmssing through that pipe.
