IMPROVEMENT IN STEAM-GENERATORS.

Specification forming part of Letters Patent No. 159,178, dated January 26, 1875; application filed September 7, 1874.

To all whom it may concern Be it known that I, WILLIAM E. HAXTUN, of Kewanee, Henry county, Illinois, have invented new and useful Improvements in Steam- Generators, of which the following is a full description, reference being had to the accompanying drawings, consisting of two sheets, in which- Figure 1 is a vertical section; Fig. 3 a vertical section, showing the upright boiler and the water-jacket forming the fire-pot, as used together.

My invention relates chiefly to baseburning steam-generators; and it consists in an improvement upon patent granted to me No. 153,486, as will be hereinafter more fully set forth and pointed out by the claim.

In the drawings, A represents a single upright boiler. The lower part has double walls a 12, forming a water-space, 0, between them. Each wall or sheet, a b, has a head, d d, riveted to it, the greater part of the space be tween the two heads being a steam-chamber, 1). Within the sheet or wall a is the maga zine E, for fuel, which is introduced through the chute F. B is a water-jacket or lining, having double walls, but no heads proper, the walls being secured to a ring at the top and bottom, forming a water-space between the walls, marked f. When this part B is used WithA it forms both a fire pot or chamber and boiler, G being the fire-chamber. This part B has a door, H, to give access to the fire. As shown, B rests on the grate; but in use I provide a ring, on which both B and the grate e are supported, the grate being within B, so that it can be replaced, when necessary. The boiler A is supported on B by means of lugs or feet g, secured to the boiler A. A and B are connected together by a suitable number of tubes, so that there shall be a free circulation from one to the other. Two such tubes, h i, are shown. An ash-pit is to be provided. 0 is a horizontal boiler, of any desired form. One or more pipes, j, form a water-communication between B and O. It forms a steam communication between A and O. l l are steam-pipes, with which heating-coils can be connected. In use it will be well to keep the head d covered with water. All of these parts A B O are to be set and incased in brick-workin the usual manner, and so that the smoke and heat will pass from the chamber Gr up around A, and then under the boiler O, and back through the tubes to a chimney; or first through the tubes of the boiler 0, if preferred. This is the most complete form of my improvements, and is adapted to those cases Where a large amount of steam is required.

When less steam or a less expensive generator is wanted, one or two parts of my invention may be used, as shown on Sheet 2 of the drawings, where Fig. 2 represents my single boiler, constructed as before described, supported by lugs g, which enter the brick-work. The lower end of the boiler should be about ten or twelve inches above the grate 0, giving room for the burning coal. m is the smokeoutlet. This furnishes a cheap, but efficient, single-boiler base-burning steam-generator.

Fig. 3 shows the same boiler A combined with the water-jacket B, before described, incased in brick-work, but without the horizontal boiler. The part B is suitably supported, as before; the two parts A B are connected by tubes 12; A rests upon B, and the fire is within B. B serves the double purpose of a boiler and fire-chamber. This form furnishes more boiler-surface than the last described, without largely increasing the cost.

In Fig. 4 is represented the water jacket or boiler B combined with a horizontal boiler. As shown, B does not rest upon, but its lower end is above, the grate 6, so as to form a magazine for coal to be introduced through a chute or door. B and O in this figure are to be secured together, and provided with water-tubes a, passing from one to the other. The parts are to be inclosed in brick, in such a manner as to provide a fire-pot between the grate and magazine, with a passage for smoke outside of B. Any space between B and O is to be carefully closed by masonry or otherwise, so as to force the heat and. smoke to pass outside of B; then they can pass under the boiler G, then through its tubes to the chimney.

In Sheet 1 I have shown all the parts of my invention combined to be used together.

furnishing a support for the boiler substan= tially as and for the purpose specified.

2. The combination of the single upright boiler A, water jacket or boiler B, and horizontal boiler 0, all constructed and operating substantially as and for the purposes specified.
