UNITED `STATES PATENT OFFICE.
JACOB HIBBARD, OFl HERMITAGE, NEW YORK.
FEED-WATER APPARATUS FOR STEAMLBOILERS.
Specification of Letters Patent No.
To all whom it may concern:
Be it known that I, JACOB HIBBARD, of Hermitage, in the county of Wyoming and State of New York, have invented a new and useful Improvement in Modes of Supplying Boilers with Water; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making part of this specification.
The nature of my invention relates to the construction and mode of operation of feeding cylinders to supply steam boilers substantially as hereinafter represented and described.
With reference to the accompanying drawings, Figure l, is a plan, Fig. 2, an elevation, Fig. 3, a sectional elevation, and Fig. 4, a sectional plan, illustrating my improvement.
A, is a tank or reservoir, and E, the boiler to be supplied from said tank. i Between the two is arranged the casting B.
Vithin the casting B, is closely fitted so as to be free to rotate the cylinder C. Projecting upward from the cylinder is the shank C1 around which is fitted the bearing piece D, which serves as a bearing for the shank C1 and alsokeeps the cylinder in its place in the casting B. This bearing piece D, is secured by the two bolts A'. Cylinder C, is provided with a chamber C2. This chamber opens through the side of the cylinder in one place only. In the casting B, is a passage B1 leading from the cylinders surface to the interior of the boiler, E. This passage B1 corresponds in size and shape to the opening of the chamber C2 through the side of cylinder C, and opens into the boiler E, at a point lower than that where it leaves the surface of the cylinder C. In the casting B, opposite the passage B1 is the passage B2 of similar size and shape and leading from the surface of the cylinder to the water tank A. The water tank should in all cases have its bottom at an eleva-tion as high at least as the bottom of the chamber C2 in the cylinder. The set screw b, forms a pivot on which the lower end of the cylinder turns so as in some measure to relieve it from the friction upon its surface and lower end to which it would otherwise be subject. A gear F, is attached to the shank C1 into which plays the pinion G. This pinion G, is

attached to a shaft having itsvbearing in stand I-I. On this shaft is the pulley l I, which may be driven :by a belt passing from any suitablerevolving shaft connected with the engine `or otherwise, provided asuitable speed with certain power is secured. The cylinder C, thus being made toA revolve continuously should also revolve with a speed somewhat exceeding in the number of revolutions per minute the number of times which the chamber C2 would require to be filled and emptied into the boiler to keep the water therein at the proper height. The upper side of the opening of the passage B1 into the boiler should correspond to the required height of water in the boiler in all cases, as indicated by the line E1 in Fig. 3. The parts may be made of cast iron or other material suited to this class of work.
Having thus set forth the construction of my improvement I will proceed to describe the operation.
The boiler having been filled, the steam got up and the engine set in motion thereby causing the cylinder to revolve as described so soon as the opening into chamber C2 connects with the passage B2 from the water tank, the water from passage B2 begins to fill it and before the connection ceases by the opening of chamber C2 getting past the passage B2 the chamber C2 is filled with water and immediately by the con tinued revolution of the cylinder the opens ing connects in turn with passage B2, when if the water in the boiler is below line E1, the passage B will be full of steam which at once rushesinto and fills chamber C2, the steam being lighter than the water, the water must fall down into the boiler the cylinder passing on in its revolution brings the opening chamber C2 again in connection with passage B2 and so exposes the steam with which it is filled to contact with the water thereby instantly condensing it or allowing it to pass up through the water so the water again fills chamber C2 and is deposited in the boiler when the connection again occurs with B1 as before. This process goes on till the water attains the level E1 coinciding with the top of the opening of B1 into the boiler after which the steam cannot enter passage B1 so then its pressure upon the water keeps it up in contact with cylinder C, so preventing any more water passing into the boiler until the Water in the boiler falls again below line El as described.
Thus the water is kept at the proper height and the evils and dangers consequent upon too much or too little water in the boiler effectually avoided. 'While the water remains above line E1 the water in the boiler is forced up by the pressure of steam against the cylinder C, and there is consequently an alternate mixing of the hot water in the boiler with the water in the chamber C2 and of that with the water in passage B2 this serves to warm the water in the tank before entering the boiler.
Having described the construction and operation of my invention what I claim
