THOMAS FEARON, OF YONKERS, NEW YORK.

STEAM-HEATER.

SPECIFICATION forming part of Letters Patent No. 484,787, dated October 25, 1892. Application filed May 1, 1891. Serial No. 391,215. (No model) To all whom it may concern.-

Be it known that I, THOMAS FEARON, of Yonkers, in the county of Westchester, in the State of New York, have invented new and useful Improvements in Steam Heaters, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to an improved steamheater, and has for its object the production of a durable, simple, and highly-efficient construction possessing a great amount of heating-surface for producing a maximum degree of steam with a minimum amount of fuel, and capable of being readily repaired without the exercise of great skill or ingenuity and without preventing the operation of the entire boiler while a portion is being repaired.

To this end the invention consists, essentially, in a pair of steam-drums, a rectangular water-containing base, a series of upright heads or manifolds arranged alternately in two rows at the center of the heater and having their upper extremity connected to one of the steam-drums and their lower end to the water-containing base, heating-sections projecting from each of the outer faces of said heads and composed of a series of U- shaped tubes or pipes arranged one within the other with their opposite ends connected to the heads or manifolds.

The invention furthermore consists in a superheater depending from the end of the drums and mounted between the top and bottom legs of the inner U shaped heating-tubes, in deflecting-plates also mounted between the opposite legs of said pipes for passing the heat around the superheater, and in the detail construction and arrangement of the parts, all as hereinafter more particularly described, and pointed out in the claims.

In describing this invention reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figures 1 and 2 represent, respectively, elevation and top plan views of my improved heater. Fig. 3 is an elevation taken at right angles to Fig. 1. Figs. 4 and 5 are horizontal sectional views taken on the respective sectional lines ax and y y, Fig. 1. Fig. 6 is an enlarged horizontal sectional view of a portion of the heads or manifolds and the heating-pipes projecting therefrom, illustrating particularly the construction and arrangement of these parts and the plug for permitting expansion of the tubes; and Fig. 7 is a horizontal sectional view of a modified form of heater.

It is well known that the aim of manufacturers of boilers designed for use in steamlaunches, &c., is to make the boiler as low down as possible and at the same time provide a great amount of heating-surface, and so construct the boiler that it may be readily repaired at a minimum expense andby an or dinary pipe-fitter, and be perfectly free to ex pand and contract in operation.

My invention is designed to meet the abovementioned requirements and to furnish a maximum amount of steam with a minimum amount of occupied space for the heater and required fuel.

A represents the water-containing base consistin g, preferably, of a series of pipes at a a a, joined by elbows a. This base may, however, be composed of a single casting, if desired.

B represents the steam-d ru m, of which there are preferably two, arranged lengthwise from front to back of the heater and slightly separated from each other, with their opposite ends connected to the base A by pipes B for passing to the water-containing shell any water which may accumulate in the drum B.

0 represents the upright or vertical hotwater head or manifold, arranged at the center of the heater for supporting the projecting heating-pipes D. These heads are preferably arranged in two rows and alternate with each other, as best seen at Fig. 6. The upper end of each head 0 is connected by a U-shaped tube or pipe 0 to the top portion of the farthest drum, as best seen at Figs. 1 and 2, and the bottom portion is connected by an L-shaped tube 0 to the adjacent pipe a, whereby the steam passes to the steam-drum and the sediment to the cold-water-containing base A. It will be noted upon reference to the drawings that the connecting-pipes 0 have one or more bends and extend by and ICO laterally overlap each other. The heatingsections D preferably project from the outer face of the manifolds or heads Oto the outer face of the grate, (not shown,) and are arranged in the form of a nest, consisting of a series of U-shaped tubes 01 d d (1, having their opposite ends secured to or communicating with the heads 0 and their central portion projecting outwardly to the extreme wall of the heater. As best seen in Fig. 6, the heads are cylindrical and are provided with a nipple or plug 0' for closing an opening 0 arranged in the wall opposite to the entranceopening for permittingthe entrance of an expanding-tool adapted to expand the tube for holding the same firmly in position. As also seen in Fig. 6, this arrangement enables the tubes to be mounted extremely close to each other, since the projecting portion of the nipple projects into the space between the adjacent walls of the heads. It is evident, however, that instead of composing the heatingsections D of tubing they may be composed of piping, in which case the plugs 0' may be dispensed with. In case one of the sections needs repair, it may be readily removed by removing the pipes c and O, and the holes for said pipes may be then plugged, and the entire heater maybe operated without the injured heating-section.

E represents the superheater, having one ende depending from the drum B and the other formed with a series of coils and mounted between the opposite legs of the central heating-pipe d, as best seen at Figs. 1, 2, 3, and 5.

For the purpose of rendering the contact of the heat with the super-heater more positive and certain I provideaseries of bent deflecting or baffle plates E, also mounted between the opposite legs of the inner heating-tubes d and bent around the separate legs of each coil.

Upon reference to the foregoing description it is evident that the peculiar arrangement of heating-coils aflords an unusual degree of heating-surface in proportion to the space occupied, and it is therefore evident that the heater or boiler may be correspondingly lowered in proportion to its capacity. Moreover, the steam is brought to an extremely-dry condition, being passed from the upper end of the drum 0 to thehorizontal steam-drums B, from which any water is constantly drawn by the pipes B and thence through the superheater before its passage to the engine.

The heater may be readily repaired. Its construction is simple, efficient, and durable, and permits a great amount of expansion and contraction of the parts. The water preferably enters into the lower shell A through the pipe F, and the sediment which accumulates within the lower shell A may be blown ed by means of a pipe G, extending from said shell.

The L- shaped pipes 0 form the fire-box, and for the purpose of my invention I have deemed it unnecessary to illustrate here the fire-grate, the fire-brick, which may be placed on the outside of the pipes O, or the outer shell, all of which parts may be of the ordinary or any special construction.

At Fig. 7 I have shown a modified form of heater, in which the heads or manifolds are rectangular in cross-section and consists of separate halves (3 0 adapted to be drawn together by bolts 0 These heads are illustrated as slightly separated to allow for expansion, and contraction, but, if desired, may be in direct contact with each other. Projecting from the outer walls of said heads or manifolds are curved pipes arranged disposed in two rows, with the pipes alternately arranged with each other and with the outer ends of each pair curved one over the other and considerably separated in order that the entire space may be broken up and the products of combustion compelled to impart their heat to the pipes without the presence of any space of easier passage.

The operation of my nvention willbereadily perceived from the foregoing description and upon reference to the drawings, and it is evident that considerable change may be made in the detail construction and arrangement of the parts without departing from the spirit of my invention.
