30 throughout the specification and drawmgs My invention relates to'a device for. blowing out, washing and refilling locomotive boilers and is for particular application 'for points, such as round houses, where locomotives are received and cared for. 'One object is the provision of means for reduc-- ing the smoking of locomotives in round houses. Another object is the provision of means for initially heating locomotive water and steam, or for initially supplyin a locomotive with water and steam whi e minimizing the necessity of initial locomotive firing in order to raise steam. Another obfeet is the provision of means for clearing and cleaning the locomotive boilers. An-

other object is the rovision of means 'for employing the-heate water and steam from the locomotives being cleaned for heating and supplying water and steam to outgoing locomotives. 7

Other objects 'will appear from time to time in the course of the specification and claims. P y

I illustrate my invention more or less diagrammatically. 1n the accompanying drawm s, wherein- I iigiire 1 is a plan view; and p y Figure 2 is an elevation.

Like parts are indicated by like symbols Whereas my invention is fparticu arly adapted for use with round houses the structure of the round house itself is omitted since it forms of itself no part of the resent invention and since a round house s owing is unnecessary for the understanding of the present invention. I

I Referring to the drawings herein it will be understood that A indicates a blow-out pipe, that is to say a connection which is made, through whatever intermediate means may be necessary, with the locomotive boiler.

It will be understood that when the locomotive is brought into the round-house for 5 servicing, a connection with the blow-out pipe A is made and the water and steam in the locomotive boiler is exhausted through such pipe into the separator A. Such separator is in the form of a cylinder A and a 0 bottom A, the blow-out pipe being provided with a tan ential connection A intermediate top an bottom of said 0 linder.

. A is any suitable outlet valve throng which sludge, dirt and other impurities may be u exhausted, by the passage A to anysuitable sewer connection, such as the catch basin top A. It will be understood that the valve A is thermostatically operated in responseto the heat of the steam andwater within the separator A. I do not claim the employ- 00 ment-of any particular thermostatic valve I but I illustrate a valve which is made responsive to the temperature of the steam or water by means of a pipe A extending from the tan ential connection A to the cylinder A of t e valvejcontrol means. The pipeA is shown as having the branches A. The circuit is completed by the exhaust connection A which branches as at A.

As the mixed water and steam passes from 7 the blow-out pipe into the separator a separation is effected, the impurities settlin to the bottom for disposal as above discri d. The steam passes through-the passage B, from the top of the separator A to the refill tank B Thissteam tends to heat the water which,- as below described, is supplied to the refill tank for refilling the boilers of outgoing locomotives. The urified' waterpasses from the separator A. y the line B l! to the washout tank B the purpose of which is to supply water for washing out 1000- motive boilers. The water so drawnpassea from the washout tank B by the pipe line B and through thevalve B to an suitable. I pump B herein diagrammatical y shown as electrically operated by the motor .B. Such pump delivers water along the liquid line 13 which extends to thepoint of. use, for example in a'locomotive round. house, I. and may be provided with an "suitable number of branches, not herein s own. Since .it is desirable to have the washout water at a temperature not too hot for use forexamrge at 120 F., I provide a cold water line incommunication with the passage B. This cold water serves to dilute the hot'water of the washout tank, when necessar in order a to hold down the temperature 0 the water su lied for boiler washout purposes. rom the refill tankB water is drawn through the liquid line C and pump G,

actuated by the motor C for delivery along the water line C through the air chamber C to. the boiler C. The boiler may be heated in any suitable manner but is herein shown as heated by any suitable oil burner.

The details of the boiler do not per se form any part of the present invention but I illustrate the boiler as including besides the cylindrical portion C a heater (1 provided with an oil burnin device C having the two injector nozzles diagrammatically shown as C". I illustrate diagrammatically automatic means for actuating the oil burner in response to fluctuations in temperatures. Thus I show a Y connection C at the top of the cylinder C one arm of which is provided with a safety valve 0 and the other with the line C extending to the burner device C. I donot illustrate the details of the pressure control since it forms no part per se of the present invention, but it will be realized that any suitable means may be employed for varying or cutting off the flame of the burners in response to pressure variations.

In addition to the pressure control I provide any suitable temperature control whereby the flame is turned up and down or on and off in response to variations in tempera; ture. I do not describe or show the details of such temperature control, since they form no part of the present invention but I do illustrate the thermostatic element C in communication, through the pressure line C, with the burner control mechanism C.

In order to provide relief means for the boiler and cylinder C I nection Dthe two arms 0 which extend to the refill tank B In one arm is positioned the automatic pressure relief valve herein indicated as D, operative to permit the contents of the boiler C to blow off into the refill tank B when a predetermined pressure is exceeded. D indicates a thermostatically controlled heater valve adapted to permit the contents of the boiler-C to flow into the refill tank B when a predetermined temperature is reached. The refill tank thus not only supplies water to the boiler C, but serves also to relieve the pressure therefrom, thus preventing any water waste. Furthermore the circulation of water or steam into the refill tank serves to maintain the temperature of the refill tank at or above the desired minimum. The refill tank B is also supplied with a drain pipe D extending from the bottom of the refill tank to the catch basin top A. D is any suitable control valve therefor.

The tank is also provided with an overflow line D, extending from the upper part of the tank to the catch basin top Extending from the boiler C is the refill line E which may extend to around house or other point of use and which serves to deliver to the boilers of the outgoing locomotives hot water and steam. The water and steam so delivered may for example be at a. temperature of 340, and under high pressure.

It will be realized that whereas I have described and shown a practical and operative device that nevertheless many changes rovide a Y con-.

might be made in the size, sha e, number and disposition of parts without eparting from the spirit of my invention. I therefore wish my drawings and description to be taken as in a broad sense illustrative and diagrammatic rather than as limiting me to my specific showing herein made. I

The use and operation of my invention are as follows:

In the application of my invention to round house practice the incoming locomotives are connected to the blow-out pipe A and mixed water and steam is blown from their boilers into the separator A The steam passes thence by the passage B to the refill tank 13; The water passes about the line B to the washout tank B". The refuse or sludge passes through the passage A to the catch basin. The escape of the sludge is controlled by a thermostatic valve which so operates that when hot water and steam are flowing into the separator, the valve is closed in response to the high temperature. When such water and steam have been exhausted from the separator the drop in temperature permits the control valve to open and to exhaust the sludge.

The water which escapes along the line B is employed for washin out locomotive boilers or for other uses an is moved by the pump B. It may be diluted with cold water flowing through the line B".

The refill tank is the water source for the refilling of the outgoing locomotives. VVatcl' asses thence, driven'by the ump C to the oiler C". The air cylinder serves to provide the necessary air cushion. Hot water, under pressure, is exhausted from the boiler C along the refill line E to the round house for suppl to the outgoing locomotives. Heating 0 the water in the boiler C is controlled both by pressure and by temperature as above described, the flame of the burner oing on and off in response to increase or ecrease, both of pressure and of temperature. Also water from the boiler C may circulate back into the refill tank B through the line D and the automatic pressure relief valve D and the thermostatically controlled relief valve D.
