CHARLES L. KING,.OF NEW YORK, (BROOKLYN,) NEXV YORK.

BOILER-FEEDER.

.aPECIFIGATION forming part of Letters Patent No. 673,543, dated May 7, 1901. Application filed \Tune 15, 1900. Serial No. 20A35. (No modem Toall whom it may concern.-

Be it known that 1, CHARLES L. KING, a citizen of the United States, residing in Brooklyn borough, city and State of New York, have invented an Improvement in Boiler-Feeders, of which the following is a specification.

My invention relates to supplying steamboilers with water by a new and automatic device instead of by the usual methods of pumps or injectors. By this new method the water in the boiler can be kept at a proper height without care on the part of the engineer.

The accompanying drawings, forming part of this specification, show the general form and detail of the invention, in which- Figure 1 is an elevation of the feeder in connection with boiler, partly sectional. Fig. 2 is the same view of section with parts in different position. Fig. 3 is a sectional elevation at right angles to Figs. 1 and 2. Fig. 4 is a section through valve E as shown in Fig. 3.

Like letters refer to like parts.

The main portion of this invention consists of an outer shell and an inner chamber, the outer shell A being bored out, (preferably larger at one end than the other,) and an inner shell or chamber B, turned and fitted steam and water tight into shell A and capable of being rotated or oscillated in relation to shell A.

In the outer shell A is an opening A, with water-pipe connection from reservoir and an opening with pipe A communicating with water-space in boiler M.

S represents an opening in shell A and pipe connection to steam-space in boiler M.

E is an opening through shell A, with checkvalve, as shown in Figs. 3 and 4.

In chamber B are openings corresponding to the openings in shell A.

In Figs. 1 and 3 the opening B in chamber B is shown opposite thewater-supply opening A, and in Figs. 3 and 4 is shown the opening B opposite the valve-opening E.

In Fig. 2 the opening B is shown opposite opening into pipe to boiler A B is a projecting stem or shaft of B, passing through cap-plate F and through stuffingbox.

F is a flange on shell A, to which F is secured.

L is a lever fastened to B and operated by connecting-rod L, the rod being actuated by any suitable machinery.

In Fig. 1 the water-chamber B is shown in position in relation to water-level in boiler.

The action of this device is as follows: The water-inlet passage A being open to chamber B through B, as shown in Figs. 1 and 3, and the opening B being opposite valve E, the other openings being closed, the water can flow by gravity or pressure into the chamber and any air or gas can find exit through valve E until the water reaches the floating valve and closes the opening. This operation of filling is done while the lever is moving up to position shown in Fig. 1' and while in that position and while the lever moves downward, and with it the chamber B, rotating in shell A, until the opening at A is closed by the solid wall of B passing the opening A. The lever and the chamber continue to move until the opening B in chamber comes opposite to opening in feed-pipe A At the same time the opening B will have arrived opposite opening of steam pipe S, when the pressure of steam and water will be equalized and the water will flow down to bottom of boiler. The level of the Water in chamber and in boiler will be the same. When the water in the boiler is as high as the top of the chamber, as at m, the chamber will remain full, and as no more water can enter the continued action of the lever and chamber will have no effect until the level is reduced, when water will flow in at each motion sufiicient to supply the vacancy, so that the device can be in continual action, requiring no attention from engineer to keep the Water-supply in boiler at correct level.

In Fig. 1 the supply-pipe A is shown to drop below the place where it enters the boiler, as at A The purpose of this is to prevent excess of heat from the boiler reaching the cham ber B. This can be accomplished by a sufficient drop of the supply-pipe below the boiler or by a sufficient length of supplypipe between the chamber and boiler, and under some conditions by a check valve, thereby providing for a temperature in chamber 13 lower than the evaporating-point and avoiding back pressure to pipe A and consequent hindrance to water-supply.

Having described my invention, What I desire to claim and secure by Letters Patent 1s In a boiler-feeder, the shell A having inlet S for steam from boiler, Water-inlet A, wateroutlet A air-vent E with floating valve for 10 closing the vent, and a, pipe A to the boiler,

a, portion of the pipe being at a lower level than Where it connects to the boiler, for purpose described, in combination with the inclosed oscillating chamber Bhaving openings B, B and B substantially as shown.
