UNITED STATES PATENT OFFICE.
GEO. XV. BAINS, OF NElVBURGI-I, NEW YORK.
STEAM-BOILEB..
Speccaton of Letters Patent No. 29,615, dated August 14, 1860.
To all 'whom t may concer/n:
Be it known that I, GEORGE lV. BAINS, of Newburgh, in the county of Orange and State of New York, have invented a new and Improved Steam-Boiler; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l, is a central vertical section of my improved boiler. Fig. 2 is a horizontal section of the same in the plane indicated by the line w, of Fig. 1.
Similar letters of reference indicate corresponding parts in the several gures.
The object of this invention is to obtain a very cheap simple and strong steam boiler of as small a size as may be desired capable of using fuel very economically, and to this end it consists in a boiler composed of a lower annular water chamber, and an upper annular water and steam chamber, connected by two or more concentric circular series of upright water tubes the inner series of which have bars arranged between them, extending from their bottoms where the grate is placed, nearly to the top thereof, to form a central circular lire box and the outer series of which are surrounded by a curtain like cylinder extending from the bottom of the upper steam and water chamber nearly to the lower water chamber, and the whole being surrounded by an iron casing with which the chimney is connected all substantially as hereinafter described.
A, is the lower water chamber of annular form whose central opening c, constitutes an ash pit and draft hole.
B, is the upper water and steam chamber, of` the same external diameter as A, and whose central opening I), constitutes a feed hole which is to be fitted with. a door or lid at the top to be opened for supplying the fuel.
O, C, and D, D, are two concentric circular series of water tubes connecting the chambers A, and B, the inner series O, O, being arranged not far from the central openings a, b, and the outer series D, D, about midway between O, C, and the exteriors of the chambers A, B. The `chamber A, the tubes O, C, and D, D, and the lower portion of the chamber B, constitute water space, and the upper portion of the chamber B, constitutes steam space. The chambers A, and B, may be made of stout cast iron, the bottom c, of the lower chamber A, and the top (l, of the upper chamberB, being composed of separate plates which are bolted or screwed to flangese, and f, formed around the bottom and top of their respective chambers. These flanges are represented as projecting outwardly from the bodies of the chambers see Fig. l, but they may be arranged to project in the opposite directions.
E, is the grate, of circular form arranged concentrically about or nearly on a level with the top of the lower chamber' A. This grate may be hung on pivots like the grates of most stoves for the purpose of enabling it to be shaken to stir the fire.
F, F, .are the upright bars arranged between the tubes C, C, constituting the inner series and combining with the lower parts of the said tubes to constitute the lire box. The innerfaces of the said bars are of such width as to enable them to rest against the inner sides of the tubes but to leave nearly half of the tubes exposed to the direct action of the radiant heat of the fire on the grate and to the ascending flame and heated gaseous products of combustion. These bars rest upon the top of the lower chamber A, and ext-end about three fourths of the way up the said tubes and may be so constructed that their own weight tends to hold them out against the tube-s, which construction enables them to be inserted and drawn out through the opening b, in the upper chamber B.
G, is the curtain like cylinder which surrounds closely the outer series of tubes D, D. This cylinder which may be of sheet iron is attached to the bottom of the upper chamber B, and extends about three fourths of the distance to the top of the lower chamber A.
H, is the outer casing surrounding the two chambers A, B, and the tubes, fitting closely around the top of the upper and bottom of the lower chamber and close between the outer flanges of the said chambers; or if the chambers have inner flanges for the att-achment of the plates c, and d, they should have small flanges or proj ecting Vrims to abut against the ends of the said cylinder H. The exteriors of the chambers should be made slightly conical to leave spaces between them and the cylinder H, as shown in Fig. 1.
I, is the chimney connected with one sideA posed inner sides of the tubes C, C, and the i interior of the opening in the upper cylinder, over the tops of the bars F, F, and between and around the upper parts of the said tubes C, C, and D, D, under the curtain like cylinder G, in contact with the top of the lower chamber and bottom of the upper one and upward between the cylinders G, and H, and around the exterior of the chambers A, B, and escape by the chimney. The whole of the chambers A, and B, with the exception of the top plate CZ, of the latter and the bottom plate c, of the former, the Whole of the tubes D, D, and the whole of the tubes C, C, with the exception of the parts in contact with the bars F, F, present themselves to the contact of the iame and heated gaseous products of combustion while a very large portion of the tubes C, C, and a portion of the upper chamber A, present themselves to the radiant heat of the body of incandescent fuel upon the grate, and hence the fire flame and gases act upon a very extensive and efective heating surface thus producing a very rapid generation of steam` which collects in the upper part of the chamber B, whilea very complete and perfect circulation of water is produced in an upward direction in the hotter tubes C, C, and in a downward direction in the cooler tubes D, D. In boilers of considerable size an intermediate concentric series of tubes may be applied in a similar manner between C, C, and D., D, and in such case the curtain like cylinder G, maybe arranged either between the intermediate and outer series of tubes, or outside of the outer series as represented. Four or more iron bolts may be employed to secure the upper and lower chambers together and such bolts should preferably pass each through one of the tubes so that they may expand as nearly as possible in the same degree as the tubes.
What I claim as my invention, and desire to secure by Letters Patent, is-
The combination of the upper and lower annular chambers A, B, connected by two or more series of water tubes C, C, D, D, the bars F, F, or other filling between the inner tubes, the curtain like cylinder G, and the outer casing H, t-he Whole arranged substantially as herein specified.
