CHARLES WRIGHT, OF OATLETTSBURG, KETUCKY."

IMPRVEMEN'T IN BlLER-FEEDERS.

Specification forming part of Letters Patent No. 147,@86, dated February 24, 1874; application filed l December 2o, 1873.

To allwhom it may concern Beit known that I, CHARLES WRienr, o Oatlettsburg, in the county of Boyd and State of Kentucky, have invented a new and useful Improvement in Boiler-Feeder, of which the following is a specification:

Figure 1 is a vertical section of my improved boiler-feeder, taken through the line .r Fig. 2. Fig. 2 is a horizontal section of the same,

taken through the line y y, Fig. l.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved device for feeding water to a steamboiler, which shall be simple in construction, convenient in use, easily operated, and reliable in operation. The invention consists in the case, the bottom, providedwith the four passages and the two stops, the valve, provided with the two passages and the stop, and the interior pipe, constructed and arranged to operate, in -connection with each other, a steamboiler, and a supply-cistern, as hereinafter fully described.

A represents a case or chamber, the upper end of which is made close, and which has a iiange formed around its lower end, by means of which it is bolted to the bottom B. C is a valve, which has its seat upon the middle part of the inner surface of the bottom B, and isv attached to the stem I), which passes out through the center of the bottom B, and has a crank arm or handle, E, attached to its outer end. The inner end of the valve-stem D rests against the end of a screw, F, that passes in through the closed end of the case A, as shown in Fig. l, so that by adjusting the said screw the valve O may be held to its seat with more or less force, as may be required. In the valve C, upon the opposite sides of the stem D, are formed two passages or ports, c1 c2, in such `positions thatwhen th'e said valve is in the position shown in Figs. l and 2 the passages c1 'c2 may be opposite the passages b3 b1 of the bottom B, and when the valve C may be turned one-quarter around, the said passages cl c2 'may come opposite the passages b2 b4, also boiler at a little higher level than the waterline. The passage b1 is connected by a pipe with the top or steam-space of the boiler. The passage b3 is connected with the boiler at the water-line. The `passage b2 is connected with the water-cistern, which must be at a higher level than the device. The passage b4 is connected with the cistern to convey away the steam or air from the chamber A. To the valve C, in thepassage 02, is secured the lower end of a pipe, G, the upper end of which projects nearly to the closed upper end of the vessel A, so that water may pass into and steam or air out of, and also that water may pass out of and steam into, the said chamber without the two streams interfering with each other. The movement of the valve C is limited by a stoppin, H, attached to the edge of said valve, and which strikes alternately against the stop-pin I, attached to the bottom B. By this construction, as the valve C is turned so as to make the passages c1 c2 correspond, respectively, with the passages b2 b4, the water will flow, by its own weight, into the chamber A, while the air or steam in said chamber escape-s into the said cistern, or some other receiver. Vhen the valve Gis so adjusted as to make the passa-ges c1 c2 correspond, respectively, with the passages b3 b1, the water will flow, by its own weight, into the boiler, while an equal amount of steam escapes into the chamber A. rlhe valve -crank E may be operated by hand, or by ya cam or other mcchanieal device driven by the machinery.

Havin g thus described my invention, I claim as new and desire to secure by Letters Fatent- The case A, bottomB, provided with the four passages b1 b2 b3 bt and the stops I, the valve C, provided with the two passages el c2 and the stop H, and the pipe Gr, constructed and arranged to operate, in connection with each other, a steam-boiler, and a supply-eistern, substantially as herein shown and described.

CHARLES VRIGHT.
