FEEDM-WATER QLEAI\! E R.

SPECIFJICATION forming part of Letters Patent No. 326,014, dated September 8, 1885. I Application filed April 1, 1885. (X model.) i

To all whom, it may concern:

Be it known that I, JAMES T. BRYANT, a

States, residing in Rich-j citizen of the United mond, in the county of Henrico and State of Virginia, have invented a new and useful Improvement in Feed-Water Cleaners; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in which-'- Figure 1 is a side view of the feed-water cleaner, showing its relation to the adjacent parts of the engine-frame and boiler. Fig. 2 is an enlarged sectional View of the feed-water cleaner.

This invention relates-to feed-water cleaners for which Letters Patent were granted to me on April 12,1879, and numbered 217,577; and

it consists in the improvement in the construction of the same hereinafter described.

In carrying out my invention as set forth in the specification forming a part of the said Letters Patent some difficulty has been caused by the water in the tender escaping through the discharge-cock when not wanted to do so,and other difficulties have also been met withon account of the discharge-cock and the valve situated between the cleaner and the boiler both being open at the same time. I therefore dispense with the use of said valve and discharge-cock, and employ in place of them a three-way cock constructed so as to form a part of the cleaner. I also make the strainer in the form of a tapering cylinder, and form in the upper part of the cleaner an air-vessel to assist the injector in working more uniformly.

I will now proceed to describe my invention with reference to the accompanying drawings, in which similar letters of reference indicate corresponding parts.

A represents the rear end of a locomotiveboiler; B, the truck frame or housing,in which the axle O of the rear wheels runs in suitable bearings.

D is the feed-water pipe, suspended at its rear end by a hanger, and having its other end connected to the injector or pu'mp,(not shown in the drawings,) by which the water is drawn from the tender and forced into the boiler.

/ through which the feed-waterpasses,but which I g E is the cleaner through which the feed-water passes. This is provided with the cock 6 in its lower part, and with a strainer, e, preferably made in the form of 'a tapering hollow cylinder having numerous small holes in it,

are not large enough for the passage of solid matter that would be large enough to interfere with the working of the injector or pump. The strainer e is provided with aflange, 6 by which it is seated in and fastened to the cleaner, and with a socket, 6 into which a steampipe is screwed. A dischargepa'ssage, c, is formed in the bottom of thecleaiier', and the passage in the cock and those in the cleaner are arranged after the manner of an ordinary three-way cock, so that the cock 6 may be made to connect the tender with the strainer, or the tender with the discharge-passage, or the strainer with the discharge-passage.

' The upper part of the cleaner consists of an air-vessel, e the use of which is to assist in the regular working of the injector by forming an elastic air-spring in the feed-pipe which supplies the temporary cutoff of water from the tender,caused by the sudden jolts and jars to which it is subject in working.

F is a steam-valve connected to the boiler and provided with the steam-pipe j, which passes through the top of the air-vessel e and screws into the socket e of the strainer. The cock 6 is provided with a lever, e, and with a rod, 6, attached to the end of the said lever, and extending upward into the engine-cab, so that it may be conveniently operated.

When the cock is in the position shown in the drawings, the water from the tender passes through it in the direction of the arrows and leaves all solid matter inside the strainer. To get rid of this solid matter the cock eshould be turned so as to place the strainer in communidation with the discharge-passage e and the steam-valve F'opened. The steam from the boiler will then rush down and driveall the solid matter charge-opening.

The cock e may also be used asadrain-cock to prevent the water from freezing in the pipes which connect it with the tender and with the injector or pump.

Ido not confine myself to the use of a blast the steam-pipe f out of the dis- IOO of steam for cleaning the strainer from solid matter, as a blast'of air ora current of water may also be employed for that purpose.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a feed-water cleaner having a waterinlet, the combination of a three-way cook, a strainer situated above said cock, and a steampipe provided with a stop-valve and communicating with the top of the strainer, substantially as described and shown, and for the purpose set forth. I

2. In a feed-water cleaner having a waterinlet, the combination of a threeway cock, a strainer situated above said cock, an air-vessel formed in the upper part of said cleaner, and a steam-pipe provided with a stop-valve, passing through the said air-vessel and communicating with the top of the strainer, substantially as described and shown.

3. The combination of the cleaner E, having a water-inlet and a discharge-opening, e, the strainer c,steam-pipe f,h aving stop-valve F, the discharge-cock, the lever e, and rod e substantially as described and shown.

4. The combination, in a feed-water cleaner having a water-inlet and a discharge-cock, of a tubular strainer having foraminated' sides and open at its opposite ends, and having one end communicating with the water-inlet, and a blast-pipe connected with the opposite end of the tubular strainer, substantially as set forth.

5. A feed-water cleaner having a water-inlet and an air-chamber projected upwardly above said inlet, and provided with a strainer located in the lower end of the air-chamber, and a blast-pipe, substantially as set forth.
