SYSTEM OF WASHING AND FILLING LOCOMOTIVE-IBOILERS.

Specification of Letters Patent. Patentqgd Sept, 14, 19m, Application filed June 8, 1908. Serial No. 437,385.

To all whom 'it may concern:

Be it known that I, WILLIAM WHITE, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Systems ofVVashing .and Filling Locomotive Boilers, of which the following is a specification, reference being hadto the accompanying drawings, which form a part of my specification.

My invention relates to a system more es pecially adapted for use in washing out and filling locomotive boilers, and the devices employed permit of the use of the steam and water taken from the locomotives brought into the round-housefor washing out.

The object of the invention is to provide a system wherein the water and steam blown from locomotive-boilers may be utilized; the water separated from its impurities and the cleaned water used for washing out the boilers to remove the collected sediment and scale therein; and the heat units of the dischar e from the locomotive-boilers, utilized,

as willmore fully hereinafter appear.

The further object of the invention is to provide means whereby the automaticoperation of the system will be insured as soon as the device is coupled to the locomotiveboiler and its blown-ofi' contents received, thus providing for the use of the heat-units" in connection with the-water to be used for washing and fillin the boilers after they have been blown o5.

My invent'on is illustrated in the accompanying draivings, in which Fi re 1 is an elevation of a portion of a roun -house showing a locomotive and a portion of my system with parts brokenaway in order to more clearly illustrate the invention. Fig. 2 is an elevation of the remainder of the system, showing a part of Fig. 1, in order to show the connection; a

' part also being shown broken away in orderto show the internal construction of such parts. Fig. 3, is an enlarged detail view of a portion of the system, with parts broken away.

In Fig. 1 I have shown a locomotive connected by flexible hose 1, pipes 2 and 3, with the upper part of a separating-chamber A.

The'pipe 3 communicates with chamber. Ai

-preferably at one end as shown, so that the .water and steam discharged from pipe 3,

will encounter mechanism to be later described, whereby an effective and quick separation will be insured. Leading from the top of chamber A, is pipe 4, whereby the steam is conveyed to a heater B, near its bottom. The heater B, is provided with a plurality of shelves 5, the shelves beingarranged one above the other in the manner employed in what is known as an open heater, wherein the inflowing water 1s brought into direct contact with the steam. The heater is provided at its top with a vapor-escape or conduit 7, leading into the air.

. Extending from the bottom of separatingchamber A, is a drain-pipe 8, which leads to the' sludge-chamber C, the-latter having a sewer connection through pipe 9. The separating-chamber is also connected by pipe 10 with receiving or wash-out water tank D, into which the filtered water flows and is stored until it is desired to wash out the boilers. Leading from the bottom of tank D, is an exit or wash-out line 11, which connects with a pump E. Connected with pipe 11,'before it reaches pump E, is a cold or fresh water line 12, with a tempering-valve 13, intervening, whereby the supply of cold water to pipe 11 to temper the water taken from tank D, is regulated; the valve 13, being controlled by the thermostat 14. The water under pressure then passes from pump E up through pipe 15 the pump being pro-.

vided with the usual governoras at 16, and a thermometer 17, whereby the temperature of the pressure-water may be noted.

17*, 1s a cross in which thermostat 14 is located, and from which pipe 18 leads to sludge-pipe 8; this branch being provided with a valve at 19, whereby the How into the sludge-pipe 8 is cut-off.

The wash-out line 15, connects with distributing pipe 20, which in turn is also connected with a return or circulating-pi e 21.

from

valves whereby the line may be- Tank D is provided with an over-flow I pipe 25, which extends almost to the to of the tank and connects with pipe 9 w ich leads to a sewer connection.

Suitably mounted-within tank D, at a predetermined point, is a float 26, which is connected with rod 27 which in turn connects with a valve 28, located in a branch of the cold water line 12, which branch takes into the top of tank D. The upper end of rod 27, and the end ofthe lever 29 connected to the valve-stem are provided with a series of alinedopenings, whereby the connection between rod 27 and lever 29 may be altered, thereby altering the degree of operation of valve 28 when float 26 dro s below a given I point, thus allowing a pre etermined quantity of cold fresh water to enter tankD Leading from the main cold water line 12, is

' through line 30 to the top of heater B. By

having valve 84 located in the receiving and conveying means at a point intermediate of the locomotive or initial point and the separating-tank A, the action of the blown-out steamv and water flowing in on top of the valve will compel a'positive and quick ac tionof flop-valve 34,, which in turn at once operates valve 31, permitting a flow of cold water to heater B.- 35, is another valve in cold waterline 30, which is operated by rod '36, having pivotal connection with float 37 admit live steam to the tank, t ereby in-- (see Fig. 2); the purpose of this valve and float ,is to shut oif the su ply of water to heater B, after it has reaclied a determined point.

Heater B, is connected at or near its bottom, by pipe 38-with filling-tank F, whereby the heated water may flow in'to tank F. The fresh cold water line 12, also connects with tank F; and the admission of the fresh water through pipe 12' is regulated by float 39, which is connected by rod 40 with lever 41 operatively connected with the. stem of valve 42. 4

Located in tank F is 'a thermostat 43, which controls valve44 in line 45 containing live steam which operates pump G; the thermostat admitting ressure to valve 44 through pipe 46. hen the temperature of the, water in filling-tank F, falls below a predetermined point or degree, the thermostatically-controlled valve 44 will 0 crate and creasing the temperature of the filling-water within.

The filling. water is conve ed from tank F, through pipe 47 to a pump and on through pipe-line 48 to the point of use. Line 48 is provided with the desired number of dis tributing pipes 49 which are provided with valves as at 50, and at which point the flexible hose connection with the locomotiveboiler is made when the boiler is to be filled. As is well known in devices of thiskind, it

is necessary to provide this filling-line 48 i thus utilizing all the heat-units conveyed to.

the'heat'er. This I accomplish by using valve of the nature shown at 34 and located at the point indicated, that is, intermediate of the separator and the boilers from which the products are blown. It is apparent that not only the pressure of the steam, but also the weight and velocity of the water, will immediately act on this valve and compel it to flop or tilt, permitting the water and steam to pass into the se arating and filterin tank A, where it wil impinge upon the ba e-plate 53, located immediatel' beneath the orifice of pipe 3. The effect 0 this baffle-plate 53, \is to spread the hot water and steam out in chamberor tank A directly beneath the orifice of pipe '4 and over the filter or screen 54 secured in tank A and which incloses a chamber from which out-flow pipe 10 leads to carry the filtered water to tank D. By diverting and spreading the products in the manner just described, it is evident that the steam will quickly rise within ipe 4 and flow to the heater B, as before described.

Instead of employing the bathe-plate, any

other suitable mechanism may be employed whereby the result desired may be had, but

I believe the construction shown and described, whereby the blown-out roducts are spread or thrown out somewhat in a sheet or film or spray form, to be the simplest and at the same time very eflfective.

I In the operation of my system 'the locomotive is brought into the round-house full of hot water and steam and the flexible pipes -1 are connected to the several outlets, and

the valves opened, so that the pressure in the boiler will force the water and steam through pi e 2 to main'pipe' or other receiving an conveying means 3, in which is located valve 34. The weight and pressure of the blown-out products will force open valve 34, and with it valve 31, and passing on intotank A where it impinges upon the;

diverting "mechanism or Dame-plate 53,

cease? From this tank" the steam passes directly through pipe 4 into heater B, where it comes into direct contact with a sufiicient amount of cold water admitted by valve 31 to pipe 30 taking into the top of heater B. As the degree of operation of valve 31 is controlled by the degree of movement of valve 34, the quantity of cold water admitted to heater B will be in proportion to the quantity of steam flowing into the heater, as it is evident that as the pressure of the steam and the weight and velocity of the blown-out water diminishes, the extent or degree to which valve 34 is opened will lessen, thus simultaneously diminishing the fresh water supply to the heater B, so that no greater quantity of water is allowed to flow into heater B than the amount of steam entering heater B will properly heat; thus a predetermined proportion is maintained. As previously described the proper pro ortion of water to the heat-units admitte to the heater is determined by the adjustment of the lever and rod connected 'with the valves. The fresh water is thus heated to the desired temperature, and then flows through pipe 38 into storage tank F. The

blown-out Water from the locomotive contains a considerable quantity of scaly sediment, which is forced byfilter 54 to fall to the bottom of tank A, from which oint it is. carried with a small quantity 0 water through'pipe 8 into sludge-tank C; while the hot water which passes through filter 54 in tankA, flows through pipe 10 into tank D. The water in this tank is normally maintained ata predetermined level; and whenever the Water is drawn off so as to fall beneath this level, float 26 will drop,,

which will operate valve 28, admitting water through pipe 12.- The pump E, draws the water from the base of tank D, through pipe 11; the water being maintained at the proper temperature as hereinbefore described. Pump E, forces the wash-out water through pipe 20 to the proper points where it is connected with the boiler. simultaneously with this operation, filling-water is being heated in i F, as before described, and when the boiler has been washed, itis coupled to the distributing pipes of filling-pipe 48, through which the heated fresh water is pumped from tank F by pump G. Thus it will be seen that with my'improved system the fluid contents blown' out from the locomotive, after being separated and filtered, are used, in part, for washing-out the boilers and in part to heat the water .to fill the boilers.

As appears from the foregoing description of my invention I utilize the weight and velocity of the blown-out products, tion to the pressure they exert, to automatically control a water-supply, which, in the system shown and described, is intended heater B and stored in tank.

.comprising tanks in addifor the heater of a filling-water supply; but

it is a parent that'the water-supp y may be used or any purpose other than the one set forth.

While I haveshown and described a specific form and arrangement, it will be readily understood that the same might be altered in certain details without departing from the spirit of my invention, and I do not wish to be understood as limiting myself to 'the exact construction shown and described, but
