JAMES T. BRYANT, OF RICHMOND, VIRGINIA.

FEED-WATER CLEANER.

EPECIEICATION forming part of Letters Patent No. 350,910, dated October 19, 1886.

Application filed February E). 1886. Serial No. 191,377.

T 0 all whom it may concern:

Be it known that I, JAMES T. BRYANT, of Richmond, in the county of Henrico and State of'Virginia, haveinvented a new and useful Improvement in Feedater Cleaners, of which the following is a description.

In the drawings, Figure 1 is a side view of my improvement in connection with some of the adjacent parts of the engine-frame and boiler, and Fig. 2 is an enlarged sectional view of my improvement.

The present invention relates to cleaners for use on locomotives, andis an improvement on the cleaners covered by Letters Patent granted me April 12, 1879, and September 9,1885,and numbered, respectively, 217,577 and 326,014.

In my present invention I seek to simplify the cleaner and provide a construction by which the sieve may be cleaned by the steam from the injector when the latter is pulled back, and by which both the water-inlet pipe and the injector feed-pipe may be drained, when so desired.

The invention consists in certain features of construction and combination of parts, as will be hereinafter described.

The water-inlet pipe A leads from the water-tank, located usually in the tender, and is joined to the injector feed-pipe B,which leads to the injector, and through which water is drawn and forced into the boiler.

At the juncture of the pipes A B is formed a three-way cock, 0, having port 1, leading into pipe A, port 2, leading into pipe B, and

' the dischargeport 3, out of which pipes A and B drain, and through which the steam and sediment are blown in the operation of the device, presently described.

In the cock 0 is secured the three-way plug or valve D, having ports 4, 5, and 6. By turning this plug the ports 4 and 5 may be registered, respectively, with ports 1 and 2, or ports 4. and 6 may be registered with ports 3 and 2, or the ports 4, 5, and 6 may be registered with ports 3, 1, and 2, as will be seen.

Within the injector feed-pipe, and close to the cock 0, I- arrange the sieve or screen E, which is preferably formed, as shown, in the shape of a cone having its base located next to the cock and its point or apex projecting into pipe B toward the injector. (Not shown.)

This screen stops all sediment and prevents it (No model.)

from passing onto the injector, and thence into the boiler.

By forming the screen in the conical shape shown its area is greatly increased, and less resistance is offered to the passage of the water, as will be manifest. Such screen might be formed of perforated metal or of wire-cloth; but the perforated 1netal,as shown,is preferred because of its greater strength, durability,and case of adjustment into and out of position.

In the construction shown the conical screen is provided with a radial flange, which fits be tween the end of pipe A and cock 0, and is secured by a nut, l which swivels on the end of pipe Band is threaded onto a nipple formed on the cock, as most clearly shown in Fig. 2. \Vhen the screen has become in any measure clogged by the sediment, the cock may be set to register with and connect ports 2 and 3, when by pulling back the injector the steam will blow back through pipe B, through the screen,cleansing the same,and forcing all sediinent out of the port 3.

In blowing out it will be understood ports '4 and 6 are registered, respcctively,with ports 2 and 3, and the port 1. is closed. To drain both pipes A and B, as is desired,

ports

1, 5, and 6 may be registered, respectively, with ports 3, 1, and 2.

3y arranging the screen in the injector feedpipe the use of a separate steam-pipe for blowing off, as shown in my former patent, No. $26,015, is avoided.

The plug may be turned by the construction shown, or by other suit-able device.

It is preferred in connection with the construction before described to use an air-chamber, G, by which to form an. elastic air-spring, by which to continue the pressure of water toward the injector during the temporary cut-off of water from the tender resulting from the jolting andjarring thereof in motion.

It will be understood that the thrce'way cock serves not only as a drain-cock to prevent freezing, but also to permit the exit of the hot water-,which otherwise might prevent the ejector from going to work.

It will be noticed that the screen forms a diaphragm or partition across the injector feedpipe,so that the steam, forcing rearwardly when the injector is drawn back,will clear all the openings or meshes of the screen, as is de- IOC sired. The ports 2 and 3, it will be seen, are

arranged in line with each other and with the pipe B, so that the particles removed from the meshes of the screen will be forced directly out through port 3.

Having thus described my invention, what I claim as new isv 1. In combination with the injector feedpipe, the water-inlet pipe, and connections between such pipes, a conical screen arranged within and forming a partition across the injector feed-pipc,the said screenbein g arranged with its direction of length in line with that of the feed-pipe, whereby when the injector is pulled back the steam therefrom will act equally on all parts of the screen, substan tially as set forth.

2. The combination of the water-inlet pipe, the injector fced-pipe, the cock having ports 2 and 3 arranged in line with each other and with the injector feed-pipe, and the screen 10- flange fitting between said pipe and section,

and a nut swiveled on pipe Band threaded onto the threaded nipple, substantially as set forth. 0
