SPECIFICATION forming part of Letters Patent No. 485,183, dated November 1, 1892.

Application filed June 1, 1892. Serial No. 435111 (NO model-l To all whom it may concern:

Be it known that we, PATRICK FITZGIBBONS and HENRY K. EASON, of Oswego, in the county of Oswego, in the State of New York, have invented new and useful Improvements in Steam Generators, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

Our invention relates to improvements in steam-generators, and has for its object the product-ion of a simple, practical, and effective device for generating steam rapidly and efficiently.

To this end it consists, essentially,in an upright lower shell having a top wall above the combustion-box, a drum projecting above the top wall of the lower shell and connected thereto and formed with a central chamber for the reception of the products of combustion, a heating-chamber above the top wall of the lower chamber, an upper water-containing shell within the heating-chamber, supported upon the drum or connection and connected thereto, upwardlyextending tubes passed through the top wall of the lower shell, and substantially horizontally-extending tubes passed through the peripheral wall of the drum and lengthwisely through the upper shell.

The invention furthermore consists 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.

Figure 1 is a front elevation of our invention. Fig. 2 is a vertical sectional view taken on line 2 2, Fig. 1. Fig. 3 is a horizontal sec tional view taken on line 3 3, Fig. 2, the form of the overlying water-containing shell and upper portion of the outer casing being shown by dotted lines; and Fig. 4 is a vertical sectional view taken on line 4 4, Fig. 2.

A represents the lower water-containing shell of our invention, which may be of any desirable form, size, and construction. As here illustrated, this shell is circular or rounding in cross-section and its sides are formed outer walla above its lower edge a The lower.

water-containing shell A is formed with a top wall A, composed of a top plate or wall a", secured to the outer walla at a and a lower plate or wall a", secured at 0, to the inner wall a. This construction of lower watercontaining shell forms a hollow water-containing cavity A between the walls a a a a and forms a combustion-chamber A beneath the top wall A and within the wall a. .Fuel is admitted to this combustion chamber through an opening A in the front of the walls a a, which is closed by a door A A suitable grate B is mounted 11 p011 any desirable construction of support 17 at the base of the chamber A Beneath the grate B is the ash-box 0, provided with a door 0, hinged at c to the lower extremity of the wall a, previously described.

Above the wall A of the lower water-containing shell is a heating-chamber D,inclosed by the upper end of the wall a, which is here shown as the outer shell or casing of our improved heater. The upper extremity of this wall a is provided with a suitable lining a and it will be evident that, if desired, the entire heater may be inclosed in a second outer casing of metal, brick, or other suitable ma. terial.

E is a connection or drum extending upwardly from the top wall A of the lower shell A and formed of less diameter than said said top wall. As preferably constructed, this drum or connection is formed of an outer wall 6 and an inner wall 6. The lower extremity of the outer wall 6 is secured at e to a flange a, upon the plate a of the wall A, and its upper end is provided with a flange eisecured at e to the edge of a circular opening f in the base of the upper heating shell F, presently described. The lower end of the inner wall e is secured at c to a flange a upon the plate a of the wall A, and its up per end is secured at e to a top plate 0 within the opening f. The drum or connection E is thus formed with a central chamber E directly above the combustion-box for receiving the products of combustion.

G is a series of upright tubes or lines arranged at the outside of the drum E, extending through the top wall Aof the lower shell A for conducting the products of combustion from the chamber A into the heating-chamber D.

H represents a series of substantially-horizontal tubes extending through the wall of the drum or connection E for conducting the products of combustion from the chamber E above the combustion-chamber A into the heating-chamber D. These tubes H are preferably arranged midway between the top Wall A and the base of the upper water-containing shell F.

In operation the products of combustion generated within the chamber A impinge against the upper extremity of the plate a of the Water-containing shell A and against the plate a of the top wall A of said water-containing shell, imparting thereto a certain percentage of their heat for raising the temperature of the water within the chamber A A part of the products of combustion then passes upwardly through the tubes or flues G into the chamber D and in its progress further heats the water in the chamber A The re maining portion of the products of combustion passes into the chamber E and through the tubes or flues II into the chamber D,thus

imparting heat to the water within the drum or connection E. The upper water-containing shell F, previously mentioned, is also preferably cylindrical in cross-section and is arranged in a substantially-horizontal plane above the top Wall A of the lower shell A. As previously mentioned, the base of the shell F is secured to a flange 6 upon the outer wall of the connection or drum E, and consequently this connection or drum both forms a support for the uppershell and connects the same to the lower shell for producing a circulation of Water from one to the other. As best seen at Fig. 5, the shell F is of greater length than the diameter of the drum or connection E, and consequently its extremities project beyond said drum or connection and above the flues G. The upper portion of the shell F preferably projects beyond the heating-chamberD; but the lower portion of said shell is substantially inclosed by said chamber, and consequentlythe products of combustion discharged into the same through the tubes or flues G H surround the lower extremity of the shell F and then pass to the rear end at of the chamber D between the rear wall f of the shell F and the adjacent portion of the outer wall or shell a.

I represents an outlet-chamber for theproducts of combustion, arranged at the front extremity of the shell F, and '1 an outlet or draft pipe opening from said chamber.

J are flues or tubes extending in a substantially-horizontal plane lengthwise through the shell F for conducting the products of combustion from the rear end 01 of the heatingchamber D to the outlet-chamber I, whence they escape by the pipe 2'.

K are dampers at the rear extremity of the heating-chamber D on opposite sides of the lower' portion of the upper water-containing shell F for regulating the passage of the products of combustion from the forward extremity of the chamber D to its rear extremity d, and thus governing the action of our generator.

L L are doors in the front of the outer wall a for permitting internal cleaning of our invention, and, if desired, similar doors may be provided at the back portion of said wall.

I is a door in the front wall t" of the outlet-chamber I for permitting cleaning of the pipes or tubes J.

The operation of our invention will be readily perceived from the foregoing description and upon reference to" the drawings, and it will be particularly noted that the path of the products of combustion is quite tortuous, that the heating-chamber D permits a thorough consumption of the heated gases, that the circulation between the lower and upper water-containing shellsis positive and effective, and that the parts are simple in construction, easily assembled, and d urable and effective in use and operation. It will be readily understood, however, that the detail construction and arrangement of the parts ofour generator may be considerably varied from that shown and described without departing from the spirit of ourinvention. Hence We do not herein limit ourselves to such detail construction and arrangement.

Having thus fully described our invention, Whatwe claim as new, and desire to secure by Letters Patent, is
