. This invention relates to a method of treating the water to' be used in locomotive" boilers in order to remove scale, oil and grease and prevent foaming, pitting, corl' rosion and galvanic action in said boilers.

' It has been vfound quite diflicult for a railroad company to. satisfactorily treat the water used in locomotive'boilers by placing chemicals either in the boilers or tender'tanks because of the great variety of water used along the line of the railroad. Where a v 4 chemical treatment may be suitable for one" kind of water it may be detrimental when appliedto another kind of water. It, i851 1 therefore, desirable to treat "thewater, at its sourcje,'o r in the wayside tank,"'providing it can be done satisfactorily. Attempts have been made to apply the chemicals to the way- L side tanks in liquid or powdered form through various feeding devices," but they' have not been satisfactory.

The object .of the present invention is ac-' complished by providing a methodor system of supplying the chemicals to'the wayside" tanks of a railroad in such a form and in such quantities as will. permit the proper treatment of various compositions of'water available in different localities or points along the railroad. The invention will be. first hereinafter described in connection with the-accompanying drawings, which constitute part of this specification, and then more specifically defined in the claims .at the end of the description.

In the accompanying drawings, wherein similar reference characters are used to des v 'ignate cdrresponding partsthroughout theseveral views s Figure 1 is an elevation of the apparatus 40 used in the practice of the present invention when a pump is employed for feeding the water through .thec emical holding reservoir or container, v

Figure 2 is a similar view of the appara- The pioportionate quantity of thechemical compound used in the treatment of the water actually consumed at a wayside station in a given set time is first determined and the amount of water allowed to pass through the chemical containerlor-res'ervoir 1 is made dependent on the observed or known time it takes to dissolve the thus determined quantity of chemical compound when in the form of compressed balls, spheres, or the like, with respect to thefiow of the water through the container." In order to insure the uniform dissolution of the sphericalvv shape and compressed to such a constituencythat it will take anywhere from 'chemical compound it is prepared in ball or 8 to 24 hours for it to'dissolwe under con .ditions such as prevail in the reservoir 1- wherein the balls are subjected-as mobile.

units to thedissolving flow of passing water. These spherical pieces of the chemical compound are indicated at 2 in the containers 1 in Figures 1. and- 2, said containers being shown; partly in section. While the spherical shape of the ieces or chemical compound are preferab y used because it ensures uniform dissolution and maintenance of its shape until entirely dissolved, itwill be understood that other shapes may be used which give substantially the same results. Said'pieces of. chemical compound are also preferably made in pound size so that it is not necessary to measure or weigh them to determine the numberto be placed in. the. container 1 to meet any particular requirements, but the size as well as the shape of said pieces may be varied if desired.

Where a comparatively small amount of chemical compound is required to treat the water in a particular wayside tank, the container or reservoir 1 is made smaller than where the water in another tank requires a greater amountof said chemical compound.

Any-number of different sizes of containers or reservoirs maybe employed as may be necessary to meet different requirements.

It will be noted that. inasmuch as the size and number of balls or chemical compound which will be dissolved in a certain quantity of flowing water in a given time is known, the dimensions of the several sizes of containers mayalso be determined with reference thereto. Thus, when the composition of the water to be treated requiresonly from 1 to 5 balls of the chemical compound/to be dissolved in 24 hours, a container 6 inches in diameter and- 15 inches in length may be used, while if from 6 to 25 balls of the com pound are to be dissolved in 24 hours to meet the requirements of another compound of water, then a container, which is 8 lnches g in diameter andj;30 inches in length would be employed. The size and she. e of the containers may, however, obvious y be varied according to requirements.

. Iii-Figure 1 the pipe 3 is used for pumping water-from a well (not shown) by means of i the pump 4, the water being discharged from the pump into the tank (not shown) via pipe 5. by-pass pipe 7 leads from the pipe 5.to the bottom of the container 1 while another by-pass pipe 6 extends from the top of said container to the pipe 3, so that water'is bypassed through said container around the pump when the latter is in operation. As indicated by the arrows, the suction from the pump draws water from pipe 5 through by-pass' 7 into the bottom of the container 1 and out the top passepipe 6 to plpe 5. In passing through said container the water is impregnated with the chemical dissolved from the balls 2, and

said impregnated water is drawn through the pump from pipe 3 to ipe 5 and delivered by the latter pipe to he tank,

It will be noted that the water by-passed around the pump so asto circulatev through the chemicalcontainer 1 enters said container at the bottom below the balls 2 and flows out of the top of saidcontainer so that there is no tendency for the balls to.clog up the outlet pipe as would be the case if the out-- let were in the bottom just below the balls where the inlet is in the present a paratus. It will also be noted that two -va ves may be arranged in either or both of the

pipes

7 and 6, so that one valve may be set or adj usted to permit just the desired amount of water to bypass the pump, according to the quantity of chemical it is desired to have dissolved in a, giventime and supplied to the wayside tank, while the other valve in the same pipe operated for turning the system on or off without disturbing. said set or adjusted valve. As shown in Figure 1 two valves 9 and 9' are placed in the pipe 7 and two

valves

8 and 8 also arranged in the pipe 6.-1 Either of the valves in either of said pipes may be used as the setting valve and the other used for turning the-system on or ofi. .For instance, valve 9 may be adjusted or set at any desired point and left there, and the system then turned off or on by means of the valve 9, or the same result may be accomplished by a similar use of the valves 8 and 8'.

In Figure 2 the pipe 10 through which the water is conducted to the waysidetank (not shown) has a valve 11 therein and'bypass-

pipes

13 and 12 leadin from said pipe 10 at opposite sides of sai valve 11 to the bottom and top, respectively, of the 'container 1 for the chemical compound balls 2. This form of the invention is designed to be used without a pump where water under pressure of city mains or the. like is avail-v able. The water passes through said pipe 10 in the direction indicated by the arrows and is controlled by said valve 11. The pipe 13 leading to the bottom of the container 1 is fittedwith an elbow 16 facing the oncoming current of water in the pipe '10, whereby ofsaid container via by-' some of said water is deflected or by-passed through said pipe 13, the chemical container 1..and pipe 12. It will be noted that the water enters the bottom of said container and flows out the top thereof, as in Figure 1. The by-pass pipe 13 is fitted with two

valves

15 and 15 serving the same purpose as the

valves

9 and 9 or 8 and 8 in Figure 1, while thepipe 12 is fitted with a single valve 14 although two valves may be used therein if desired. r

In order to distinguish the form or condition of the chemicals used by me from solutions, powders or small ranules, the use of which I do not claim, Istate in my claims that the chemicals are in the form of agglomerated units. While I have stated that I may use these chemicals in pound units, it is obvious that I may employ them in units of larger or smaller size, but the size should not be so small as to ap roach too closely the form of mere granufes not permitting a substantially free passa eof water between them or rendering them 'able to be carried as units out of the container 1 by the flow of the water.

I claim:

1. The method of treating water with boiler compounds at a wa side tank for subsequentuse in locomotive oilers, which comprises'establishing a flow of such water to the wayside tank, simultaneously diverig a portion of said flow, passing said dive portion over chemicals in the form of agglomerated units, in such a manner as to cause a dissolution of the chemicals and maintain only such a concentration as not to cause substantial precipitation in the untreated portionirrespectiveof whether the flow is continuous or intermittent, and reuniting said chemically treated portion' of the water with the untreated portion.

2. The method of treating water with boiler compounds at a we side tank for subsequent use in locomotive ilers, which comprises establishing a flow of such water to the wayside tank, simultaneously diverting aportion of said flow, passing said diverted portion upwardly .through chemicals in the orm of agglomerated units, in such a manner as to cause a dissolution of the chemicals and maintain only such a. concentration as not to cause substantial precipitation in the untreated portion irrespective of whether the flow is continuous or lntermittent, and reuniting said chemically treated portion of the water with the untreated portion.

3; The method of treating water with boiler compounds-at a wayside-tank for sub.- sequent use in; locomotive boilers, which to the wayside tank, simultaneously diverting a portion of said flow, passing said diverted portion through chemicals in the form of agglomerated units located within a liquid comprises establishing a flow of such water container and restin substantially on the entire bottom thereo in such a manner as to cause a dlssolution of the chemlcals and maintain only such aconcentratlon as not to cause substantial precipitation in the un-- portion through chemicals in the form-of 15 agglomerated units within a substantially sealed liquid container; in such a manner as to cause a dissolution of the chemicals and maintain only such a concentration as not to cause substantial precipitation in the un- 20 treated portionirrespec tive of whether the flow is continuous or intermittent and reuniting said chemically treated portion of the water with said flow.

- In testimony whereof-I have signed my 2 name to this specification.
