- Specification of Letters Patent. Patented March 19, 1907.

. Application filed October 26,1906. Serial No. 340,755.

.To all whom it may concern:

Be it known that I, WILLIAM WHITE, 9.

citizen of the United States, residing at Chicage, in the county of Cook and State of Illi- 1101s, have invented certain new and useful Im rovements in Systems of Washing and .Fil ing 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 washing out locomotives and for heating additional water filling the locomotives.

to be used for the same purpose and for re Other objects of my invention are the pro I vision of a n'ianually-controlled valve for regulating the quantity of tempering-water and means for malntaining such quantity at or below a predetermined amount.

My invent on ]S illustrated in the accompanying drawing, forming a part of this specii cation.

Referring to the figure, I locomotive connected through llexible hose 1 and pipes 2 and 3 with the upper portion of a filtering and separating chamber 4. From the top ofthis chamber the steam-pipe 5 extends into the water-heater 6, which-is provided with a plurality of horizontal shelves 7, arranged one abovethe other, and at the top with. a vapor-opening S, which leads to the free air. The filtering and separating chamber is provided with a drain-pipe E),-

leadinglrom the base oi the chamber to the sludge-chamber l0 and with the filteredwater exit I] which connects with the top of the main storage-tank 12. I

Leading from the base of tank 12 is the exit-pipe 13,- provided with the one-way valve 14 and the ordinary cut-oii' valve 15 and connecting with the suction side of the steam-operated pump 16. Also connecting with/the suction side of this pump is a coldwater-supply pipe 17, having the manuallyoperated valve 1.8 thorein,-arranged to be controlled by the lever 19. -.This lever is l'ulcrumed at 20 and moves between limbs of the upright forked i-nen'iber 21. This member is provided with a plurality of holes running in linethrough both of the forks such that a pin'may be inserted to prevent the handle 20 being raised above a certain limit. This pin ispreferably provided with means 'for locking or sealing It in a certain have shown a position, and another pin may be supplied tor insertion beneath the lever 20to prevent i the lever from moving downward to cut off the supply of water through the valve. The object of this arrangement isto utthe i maximum cold-water supply in the hands of the roundhouse foreman, but atthasame time to allow any of the roundhr we 1"... ads to decrease the amount of COld'rW. er sup-ply by lowering the lever 20.

i the pump, is connected thror gh the distributi ing-pipe 23 to the different parts of the roundhouse, where it is provided with branch The pressure-water exit-22, leading from pipes-24 and cut-ofl valves 25, where the hose 4 i may be attached for either filling or washing F the boilers.

The ipe 22 is provided near mining the temperature of the'water as it leaves the pump.

The cold-water-supply pipe 27 leads directly to the T-joint 28, and thence by Way 'of one branch through the automaticallycontrolled valve 29 to the top of heater 7 and by Way of the other branch through the automatically-controlled valve 30 to the top of the-pump with a t ermometer 25 for deter-.

3 the tank through the same opening. This automatically-controlled valve 29'is connected by rod 31, lever 32, and rod 33, with the float l 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 33 with the hinged gate 3.6, which is adapted to be moved by steam passing from the pipe 5 into the heating-tank. ,An open ing in the base of-the heating-tank 6 connected by the pipe 42 with the top oi the storagetank,whi ch is supplied with the overflow-pipe 43, which reaches almost to the top of the tank. The live-steam pipe 37 supplies that the pressure in the boiler will force the water and steam through the pi e 3. into the upper part of the filtering an separating the drawingaml the valves are opened so' steam through the throttle-valve 38 for opertank 4. From this tank the steam passes directly through the pipe into the heater 6, where it is brought into contact with "suHicieiltamount of cold water to form a mixture of the desired ltemperature to be admitted into thestQrage-tank 12, as will be herein after'described. The'water which is carried off from the engine contains a large amount of scaly sediment, which passes, together witha small amount ofwater, through the pipe 9 into the sludge-tank 10. The hot water whichpasses through the filter in the chamber 4 iscarried directly to the storage-tank age-tank v ter in the tank decreases in temperature. suf- 'mitted through the pipe '5it is necessary, in

order to maintain the temperature of'the water in the storage-tank. ata' edetermined degree, to admit live steam into the lower part of 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 storlt will-be seen that'whe'n the waficiently to open the valve steam will be admitted into the heating-tank and hot water will be caused to and into the storage-tank.

The pump 16 normally draws its watersup ly irom both the hot-water tank and the col -water.-supp ly pipe in proportion to the size of the openings -from such sources to the pump. It will be seen that when it is desired to furnish water for washin purposes the water directly from the supp y-tank will be too hot and the manually-operated valve 18 will have tobe opened, such that-cold water will be mixed with the hot water to temper it.

It is not desirable to ut this entirely in the hands ofthe unskille labor about the roundhouse, in that they would be liable to supply too much cold Water, and therefore wash the engines with water which was belowthe'most desirable temperature. It will be seenthat .by mylarrapqement the hot water as it leaves the storage tank is automatically maintained at a substantiallyconstant temperature, and

t-heretorein'order to deliver water to the dis-- tributing-pip'e ata predetermined temperature less than: that o the hot water it is only necessary to mix with the hot water a predetermined'amount of cold water, and as the" temperature of the cold water only'varies a .5 pi e eiablywith the season of the year t e pass down-the pipe 42- valve 18 only'r'equ-ires its minimum limitof opening to be adjusted in accordance with the change of season. For filling oses 1 .the cold water may be entirely cut; oil, and the supply can then be pumped directly from the hot-watersupply tank' -to the. distribut-" ingpipe 23.

One branch of the coldwater-sup plypipe, i I

provided with" the valve 30,'whichis connected, throughthe rod 35, with the hinged which leads to. the top of the'heating-tank,1s

gate 36*within the lower part of the heatingtank. I tank through pipe 5, will.open the gate 36 to .a greater or less angle in proportion to the The steam, whiclren'ters the heatingamount of steam being passed in, and at the same time the valve 30 will be operatedto admit cold water in a properproportion to make the resulting mixture of'substantially the temperature desired in the storage-tank; By thisdescription it is seen that I have provided a system of regulation which does not depend upon the temperature of the water passing through the supply-pipe, ,but. I

rather upon the quantity of water passing therethrough, and that my system, while-- being manually controlled in certain -of its arts, is not entirely under the control of the aborers. 5 While I have shown and described certain thereto, it being may be accomplished by the use of apparatus closure.
