BOILER-FEEDER.

SPECIFICATION forming part of Letters Patent No. 744,96 5, dated November 24:, 1903.

Application filed May 18,1903. Serial No. 157,606. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM HERRINGTON, a citizen of the United States, residing at Olive, in the county of Hardin and State of Texas, have invented certain new and useful Improvements in Boiler-Feeders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates particularly to boilerfeeders whose operation is dependent upon the rise and fall of a float; and the object of the invention is to produce an improved feeder of the kindstated. The construction is characterized by a feeding-cylinder which may be located at any desired place above the boiler and bya regulator located on a level with the low-water line of the boiler, which regulator controls a steam-supply to the feeding-cylinder, and thereby the flow of water from said cylinder to the boiler.

In the accompanying drawings, Figure 1 is a vertical section of the feeder with the parts in one position, and Fig. 2 is a similar section with the parts in the other position.

Referring specifically to thedrawings, D indicates a closed cylinder containing an axial rod K,0n which the globe-float A rises and falls. The rod works through a diametrical tube L in the float, and the tube and rod are flattened to keep the float from turning.

G indicates a sliding collar on the rod above the float, and this collar is connected by rods j to the valves of the steam-inlet pipe H and the steam-exhaust pipe 1, respectively. The collar is also connected to the float by a chain c. The said inlet and exhaust valves are at the top of the cylinder, and at the bottom of the cylinder are the feed-water inlet and outlet pipes E and E, respectively, the latter leading to the boiler. These pipes have checkvalves F and F, respectively.

At his indicated a closed cylinder of the regulator, which controls the admission of steam to the feeder D. Said cylinder contains an axial rod 0, which passes through a diametrical tube in the globe float at and guides the rise and fall thereof. The pipe I-[ to the large cylinder taps the cylinder it near the top thereof and is controlled by a valve D, connected to and operated by the float a.

At M is indicated a steam-pipe to the cylinder h from the boiler.

The pipe E, leading from the feeder to the boiler, has a branch R extending through the bottom of the cylinder it, so that the water in said cylinder is at the same height as that in the boiler.

In operation the float Ct is at the low-water line. When the water falls below the lowwater mark, the float falls and opens the valve d,'which lets steam through the pipe H into the upper part of the cylinder D, the valve of said pipe being open and the cylin der full of water, as will be hereinafter explained. The water then having equal steampressure on both sides opens by its weight the check-valve F and flows through the pipe E into the boiler. Thereupon the float A drops, which pulls down the collar G, which closes the inlet-valve of the steam-pipe H and opens the valve of the exhaust-pipe I, permitting the steam to exhaust through the latter. The cylinder is then refilled by Watersupply under any suitable pressure through a pipe E. When the float A rises, it lifts the collar and closes the exhaust-pipe and opens the steam-inlet pipe, which then has the effect of forcing the Water into the boiler, and this action continues as long as the valve (1 remains open and steam is admitted into the pipe H. When the desired water-level in the boiler is restored, the float arises and shuts the valve d, and the apparatus remains inoperative until the water of the boiler falls again.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a boiler-feeder, the combination with a casing having steam inlet and exhaust pipes, a water-inlet pipe, and a water-outlet pipe to the boiler, of a float in the casing, valves in the steam-pipes operated by the float, and a separate casing containing a float-operated valve governed by the height of water in the boiler to admit steam into the inlet-pipe.

2. In a boiler-feeder, the combination with a water-feeding chamber connected to the boiler, and having steam inlet and exhaust In testimony whereof I affix my signature pipes, and float-operated valves therein which in presence of two witnesses. respectively open and close when the chamher is full of water, and close and open when HERRINGTON' 5 it is empty, of a separate float-operated valve Witnesses:

controlling the steam-inlet pipe according to V V. A. PETTY, the height of Water in the boiler. PAULA STERNENBERG.
