FEED-WATER H EATER.

JPEOIPICATZON forming part of Letters Patent No. 327,553, dated October 6 1885.

Application filed February 9, 1885.

To all whom, it may concern.-

Be it known that I, ROBERT ONEILL, of Leadville, in the county of Lake and State of Colorado, have invented a new and useful Improvement in Boiler Feed-\Vater Heaters; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being made to the accompanying drawings, forming a part of this speciiieation.

My object in this invention is to provide an apparatus for heating and filtering feed-water for steamboilers; and it consists in the tures of improvementhereinafter described. I attain these objects by the mechanism illustrated in the accompanying dra\vings,in which similar letters refer to similar parts throughout the several views.

Figure l is a vertical section of Fig. 3 on the line 00 00. Fig. 3 is a top view of Fig. l with the cover removed. Fig. 2 is aseetional View of the regulating-float a, Fig. 1.

A represents the casing or shell, which is divided into two compartments, (marked B (3,) from the latter of which, 0, the water is taken for the supply of the boiler. The plate 1), whose edge is turned downward or at right angles with the top or face, is pro vided with holes, through which the rivets are passed which secure it to the shell A. It is also provided with a number of tubes, a, thirty inches in length, (more or less,) through which the water passes in descending from B to C. These tubes are about three-fourths of an inch in diameter, and the plate I) is provided with a sufficient number to enable the exhaust-steam which enters through the opening D and passes up through the pipes c to'come in contact with thin sheets of water only, which is heated by absorption from the exhaust-steam, which is thereby condensed,

the water returning down the tube 0 to the tank or compartment 0, through which it is conveyed through the opening D to the boiler.

The water required to be heated, besides the amount obtained by condensing the steam, is supplied by the circular pipe d, Figs. 1 and 3, which has perforations. (Shown by the dots e on d, Fig. 1.) Through these per- Serial No. 155,295. (No model.)

forations or holes the water enters the case or shell A, forming a thin spray, which, be ing cold, condenses any remaining steam that may escape through the top of the pipes c. The amount of water which passes in this way into the case or shell Ais regulated auto matically by the water f in compartment O, which, as its surface is raised by the addition of water from condensed steam or from the pipe (I, also raises the water in a, which causes the floatball 9 to rise. The float ball g is provided with a rod, a, whose other and upper end is attached to a valve, 1), which is set so that the raising of the float-ball G, which also raises the rod a, which in turn by its connection shuts 01'1" the water which passes from a supply tank through the pipe 0 and valve 6 into the circular pipe (I, and through the perforations in (2 into the case or shell A and compartment B. The water is turned on by the same means working in the opposite direction, caused by lowering the water f in the compartment 0, which, being connected with the float-case a by the pipe 01, also lowers the water in a, which operates the valve 1) in the manner described, which arrangement keeps the water f in compartment 0 at about the same height at all times. At this height a suitable faucet, f, is placed in the shell for the purpose of drawing ofii from the surface of the water f the oil and dirty matter which will come from the engine and float on the surface. In the shell or case are hand-holes (marked g) for the purpose of facilitating in cleansing out sediment. The water con tained in compartment B is hot at the top, the cold being at the bottom from natural causes. Therefore as the cold water enters from the pipe d, it at once goes to the bottom, and as it is heated goes to the top, and, when near the upper end of the pipe 0, it reaches such a degree of heat that the dirt, lime, and other materials contained in'solution are precipitated and fall to the bottom of compartment B, where they remain until removed through g.

I am aware that prior to this invention heaters have been made with pipes set in plates through which the exhauststeam passes, as

2. The combination of a shell or case, A, provided with outlet D and inlet D, float-case a attached thereto float-ball 9, rod a, valve b, and circular spray-pipe d.
