Be it known that I, WILLIAM WHITE, a citizen of the United States, residing at Chicago, in the county of Cook and State of IlllIlOlS, have invented certain new and useful Improvements in Systems of \Vashing and Filling Locomotive-Boilers, of which the following is a specification.

My invention relates to locomotive-boilerwashing systems, and has for its object the provision of an economic system for using the steam and water taken from locomotives brought into the roundhouse for washin out locomotives and for heating additional water to be used for the same purpose and for refilling the locomotives.

Other ob] ects of my invention are the rovision of automatically-controlled valires, whereby the temperature of the water for washing purposes may be controlled and the least possible manual attention.

My invention is illustrated in the accompanying drawings, in which Figure 1 represents certain parts of a roundhouse in elevation, showing a locomo;

tive and the details of the connections of the different parts of my system when constructed under one form. Fi 2 is a similar elevation in, which one o the valves is controlled, by a difierent means than that shown in Fig. 1; Fig. 3, is a diagrammatic representation of a roundhouse and the pipingand apparatus of my washer system.

eferring to Fig. 1, I have shown a locomotive connected, through flexible hose 1 and pi es 2 and 3, with the upper portion of a ltering and separating chamber 4. From the top of this chamber the steampipe 5-extends into the water-heater 6,- which 13 rovided with a. plurality of horizontal at the top with a vapor-o ening 8, which leads to the free air. The fi terin and separating chamber is provided wit a drampipe 9, leading from the base of the chamber to the sludge-chamber 10, and with the filtered-water exit 11, which connects with the top of the main storage-tank 12. Leading provided with a valve 15 and connecting with the suction side of the steam-pum 16. Also connecting with the suction si e of this pump is a cold-water supply ,pipe' 17,, having the valve 18 therein which is controlled by the thermostat 19. The pressurewater exit 20, leading from the pump, is provided with a T 21, one branch of which leads, through the valve 22, directly to the distributing-pipe 23, while the other branch leads, through the valve 24, to the thermostat 19 and by way of the byipe 25 and valve 26 also connects with the istributing-pipe 23, which after connecting with all of the pits finally connects with pipe 23, which leads back to the heating-tank. In order that the same connecting-hose may be used to admit water to and extract steam from the .top of the boiler, the valves 3' and 23 are con nected by a pipe to which the hose 1 is connected. 'The cold water-supply pipe 27 leads directly to the T-joint 28, and thence by way of one branch through the automatically-controlled valve 29 to the top of heater 7 and by way of the other branch throu h the automatically-controlled valve 30 tot o top of the tank through the same opening. This automatically-controlled valve 29 is connected by rod 31, lever 32, and rod 33 with the float 34 and is adapted to be opened whenever the float falls below a predetermined line in the storage-tank. The valve 30 is connected by a rod' 35 with the hinged gate 36, which is adapted-to be moved by steam passing from the pipe 5 into the heating-tank. An opening in the base of the heatin -tank 6 is connected by the pipe'42 with t e top of the storage-tank, which is supplied with the overflow-pipe 43, which reaches almost to the top of the tank. The live-steam pipe 37 supplies steam through the throttle-valve 38 for operating the pump and also through the manuallyoperate cut-ofl' 39 anddiaphragm-valve 40 to the lower part of the heating-tank. The valve 404s controlled by the thermostat 41, which extends into the storage-tank and is controlled by the temperature of the water therein, the thermostat admitting pressure to valve 40 through pipe 41*.

. Referring to Flg. 2, the valve 30 is controlled by means of thermostat 45, which is tank 10.

located in the pipe 5, connected between thefiltering and'separating chamber and the heating-chamber.

Referring to Fig. 3, in which thedesignation-symbols applied to Fig. 1 have been. used as far asapplicable, such figure'showing diagrammatically in addition to that shown in Fig. l the layout of piping'for .the entire roundhouse, 47 representing the pits over which the locomotives stand while being washed, and 48 representing the turntable for directing the locomotives on any of the several radiating tracks.

In the operationof my system the locomotive is brought into the r'oundhouse full of hot water and steam, and-the flexible pipes 1 are connected to the several outlets shown in the drawing, and the valves are opened, so that the pressure in the boiler' will force the water and steam'through the pipe 3 into the upper part of the filtering and separating tank 4:. From this tank the steam passes directly through the pipe 5 into the heater 6, where it is brought into contact with sufficient amount of cold water to form a mixture of the desired. tempera ture to be admitted into the storage-tank 12, as will be hereinafter described. The water which is carried oil from the engine 0011- tains alarge amount of scaly sediment, which passes, together with a small amount of water, through the pipe 9 into the sludge- The hotwater which passes through the filter in the chamber 4 is carried directly to the storage-tank by the pipe 11. The water in the storage-tank is normally maintained at the level shown by the dotted line .50, Fig. 1, and whenever the water is drawn ofi' so that it falls belowthis line the float 34 will sink, and thereby operate the valve 29, which admits cold water to the top of the heating-tank and which will eventually bring the water-level again to its normal position in the storage-tank. \Vhenever the condition is such that cold water pours into the top of the heating-tank when steam is not being admitted through the pipe 5, it is necessary in order to maintain the temperature of the water in the storage-tank ata predetermined degree to admit live steam into the lower part-oi the heating-tank. This is done by means of the valve 40, which is regulated by the thermostat 41, the latter being governed by the temperature of the water in. the storage tank. It will be seen t'hiatwhen the water in the tank decreases in temperature sufiicien'tly to open the valve 40 steam-will be. admitted into the heating-tank and hot water will be caused to pass down the pipe I 42 and into the storage-tank. p

The pump 16 normally draws-its supply of hot water from the'base of the storagetank. As this water is maintained at a higher temperature than is desirable for washing out engines, the pipe after leaving the pump is divided into two parallel bypaths, one way being provided with a thermostat 19, which controls the valve 17 and thereby admits cold water into the suction side of the pump when the temperature of the water as it passes thethermostat is greater than is desired for washing purposes. When it is desired to fill, theboiler of the engine before again starting the locomotive out, the valve 24 is closed and the valve 22 is opened, so that the thermostat will become inoperative and all of the water will be drawn from the storage-tank, thereby furnishing the water for the boiler at a higher temperature than would be necessary or desirable for washing purposes. YVhen it is desired to furnish cold water to the supply-pipe 23' .for scrubbing purposes during the day or for filling bollers which are not to be fired immediately, the valve 15 in the hot-water-supply pipe is closed and the valve 18, which may alsobe manu-.

ally controlled, is opened, so that all thewater'which passes through the pump will be taken directly from the cold-watensupply pipe 27 and will pass directly through the pipe 20- and valve 22-, which will then be opened to the supply-pipe 23.

One-branch of the cold-water supply pipe, which leads 'to the top of the heating-tank, is provided with the valve 30, whichis connected, through the rod 35, with the hinged gate 36, within the lower part of the heating-tank. The steam, which enters the heating-tank through pipe 5, will open the gate 36 to a greater or less angle in proportion to the amount of steam being passed in, and at v the same time the valve 30 will be operated to admit cold water in a proper proportion to make the resulting mixture of substantially the'temperatnre desired in the storagetank. The variation shown in Fig. 2cons1sts in controlling this cold-water supply to the heating-tank by means of the thermostat, which is governed by the temperature of the steam which is admitted'to the heating-tank. Details'of this heating-tank and of the filtering and separating tank having been described in my former application, Serial No.
