FREDERICK L. MGGAHAN, DE LOS ANGELES, CALIFORNIA; VIOLA K. WALKER, ADMIN- ISTRATRIX F SAID FREDERICK L. MCGAHAN, DECEASED, ASSIGNOR TO THE PUR- POSED MIND DEVELOPMENT SECURITY ASSOCIATION OF THE WOP'TJD, A TRUST COMPANY.

Original application filed January 3, 1918, Serial No. 210,146. Fatent No. 1,292,399, dated January 19,

1919. Divided and this application filed January 17, 1919.

To all whom it may concern:

Be it known that I, F REDERIOK L. Mo- GAHAN, a citizen of the United States, residing at the city of Los Angeles, in the county Serial No. 271,719.

5. As shown in Figure 2 and indicated in Flgure 1, this filter or purifier 5 consists of three compartments constructed of any suitable material with walls 7 and partitions 8.

5 of Los Angeles and State of California, have @penings 9 and '10 permit the fiow of water invented certain new and useful Imp-rovements in Filters, of which the following is a specification.

This application is a division from the application of the same inventor for patent for locomotive filed January 3, 1918, Serial 210,146 which became Patent 1292399 Jan. 19, 1919, and relates more particularly to the filter for the water obtained by condensation of the steam utilized in driving the turbine described in the said application.

In the accompanying drawings forming part of this specification, in which like numbers of reference denote like parts wherever they occur,

Figure 1 is a top plan view;

Figure 2 is a vertical longitudinal sec tional view;

Figure 3 is a side elevation of a locomotive showing the filter in situ; and

Figure 4 is a rear elevation for the same purpose.

The exhaust from the turbine 1 that forms the characteristic feature of the said patent, .is into the steam condenser and water-cooler 2 shown in Figures 3 and 4. The saidexhaust passes through pipes (not shown) into the said condenser 2. The condenser 2 is formed of a plurality of square pipes 3, arranged as shown in Figures 3 and 4, which, by reason of their form and arrangement, and particularly because of the serpentine course that the steam is obliged to pursue therethrough (as indicated by the arrows in Figure 3) cause condensation of the steam and its cooling because of the large area of pipe through which it passes before it reaches the exit, This exit is into pipe 4 that leads to the filter 5 (shown in detail in Figure 2). The condensing effect of the said large area of pipe is augmented by the draft that flows among the pipes .3 when the locomotive is in motion, which draft is enhanced by the hood fi that encloses the said pipes 3, except at their ends.

The water product of the condensation of steam in the condenser 2 is purified in filter through the filter, entering through pipe 4 into chamber 11; thence passing through opening 9 into chamber 12; and thence pass- 1ng through opening 10 into chamber 13. From chamber 13 the water passes out of the filter through pipe 14.

In compartment 11 is contained crushed copper glance. In compartment 12 charcoal is contained. Compartment 13 contains crushed lime-rock. V

Thus the water entering through'pipe 4 leading from condenser 2 flows 1n a serpentine course, as indicated by the arrows in Figure 2, first, through the crushed copper glance of compartment 11, then through opening 9 into compartment 12, and by the action of gravity travels downward through the charcoal compartment 12; thence it passes through opening 10 into compartment 13 where it rises throughthe crushed limerock and flowing outward through the pipe 14 to the water reservoir 15, from which it is pumped by pump 16 as distilled water to the boiler (not shown).

It has been found that the use of copper glance, otherwise known as cuprous sulphide, operatesto prevent the fine particles of oil and organic matter that might be present in the water as it comes from the condenser or source of supply from passing through the charcoal and lime rock.- When the water passes through the copper glance, the copper glance thereby becomes hydrolyzed and the hydrolyzed copper so formed serves to separate the oil and organic matter from the water and thus prevents these substances from passing to the compartments containing the charcoal and lime rock. Itwill thus be seen that there is provided a filter that will take care of the very fine particles in suspension in the water and which would pass through the charcoal or the lime rock into the boiler causing corrosion and incrustation. F

This filtering of water does away with any sediment or residue such as is commonly found in b ilers and does away with cleaning orblowing out ofboiler tubes which is% mentioned chamber being crushed copper a great advantage over types of boilers heretofore known.

It will be understood that both condenser 2 and Water reservoir 15 may be located at any suitable place on the loco-motive, and may be borne or supported thereby in any suitable manner.

Having thus described this inve tion, I hereby reserve the benefit of all ch nges-in form, arrangement order, or use of parts, as it is evident that many minor changes may be made therein without, departing from the spirit of this invention or the scope of the following claims.

I claim- 1. A filter having three vertically dispose chambers, an inlet 'at one end of the first chamber and an outlet at its other end and into the second and an exit from the second at the opposite end from. its inlet, theisaid exit forming an inlet into the third cham-' her, an outlet from the last mentioned cham her at the end thereof opposite its inlet and in alinement with the central longitudinal axis thereof, the filter material in the first glance, in the second chamber charcoal, and in the third chamber crushedlimerock.

2. Av filter divided into three vertically dis- ;posed chambers and having an inlet pipe at its beginning and an outlet pipe at the topand in alignment with the central longitudinal axis of the third chamber at its outlet, there being, a communicating opening at or near the top of and between the first two chambers and another communicating opening at or near the bottom of and between the second and thirdchambers.

3. A filter having three chambers in communication with each other so that the liquid passed throu h the filter will traverse each of said cham rs, filtering material in said chambers, the first chamber containing crushed copper glance; the second or intermediate chamber containing charcoal, and the third and last chamber containing crushed limerock.

In testimony whereof I hereunto afix my I signature.
