SPECIFICATION forming part of Letters Patent No. 474,887, dated May 17, 1892.
Application filed December 15, 1891. Serial No. 415,160. (No model.)
, act description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.
My invention relates to an improvement in steam-boilers of the horizontal stationary type and its object is to construct a boiler and arrange and dispose its-tubes and fines in such manner that increased heating-surface will be presented, thus facilitating and expediting the generation of steam.
My invention consists in the combination, with the main body portion of a steam-boiler, of two or more external semi-cylindrical tubes of large diameter, located beneath the boiler proper, one at or near each end thereof, said tubes communicating with the boiler directly on opposite sides thereof, and also communicating with each other by means of interposed horizontal tubes of less diameter; also, in the combination, with the boiler proper, of fines of varying diameters extending through the same from head to head and provided with transverse tubes arranged in spiral form and relation to each other and located at a sufiicient distance apart to permit the ready passage of the products of combustion between them; also, to certain details of construction and arrangement hereinafter described and claimed.
In the accompanying drawings, Figurel represents a side elevation of my improved steamboiler, showing the arrangement of the external tubes and partly broken away to show the fines and the arrangement of the transverse spirally-arranged tubes therein. Fig. 2 is an end elevation of the same, showing also the Water-supply pipe.
The drawings show simply the boiler and its connections as far only as is necessary to illustrate my improvements therein, the firebox, brick casing, 850., being omitted, as my improvements lie only in the construction of the boiler itself, having no bearing upon matters outside thereof.
A represents the boiler proper, being made cylindrical in form and composed of metal plates riveted together at their joints in the usual manner.
A and A indicate the heads or ends of the boiler, also secured by rivets in the usual Well-known manner.
B, B, B and B are the fines, made cylindrical in form and extending through the interior of the boiler from end to end. These fines may be of various diameters, and need not necessarily be cylindrical in cross-section. It will be apparent that the ends of the boiler will thus be closed, except at the orifices at the front and rear of the fines.
Z) 1) indicate short tubes extending transversely the fiues just described, and adapted to permit the water to pass through the fines, where it may be exposed more directly to the hot air traversing said fines. These tubes 1) b are arranged, relatively to each other and to the fines, in spiral form, as clearly indicated in both figures of the drawings. This arrangement facilitates the passage of the products of combustion through the flues and between and around tubes therein.
0 and 0' indicate tubes of comparatively large diameter located one at or near each end of the boiler proper. These tubes extend around beneath the boiler and communicate with the interior thereof at points 0 and 0 approximately in or slightly above the horizontal plane of the axial center of said boiler and also at a point 0 underneath the same. The tubes C and 0 further connect directly with each other through a series of horizontal tubes 0 of lesser diameter, the latter, as shown, underlying the boiler and being directly and primarily exposed to action of the heat. The tubes C and C are further made up of several sections connected and clamped together by means of bolts, passing through collars or annular flanges C on the adjacent ends of said sections.
D represents the supply-pipe through which the water is conducted to the tubes (J, O, and O thence to the interior of the boiler, and through the spirally-arranged tubes extending through the fines.
The operation, which will be readily understood, is as follows: The fire-box being located under one end of the boiler, the products of combustion are caused to pass along under the body of the boiler proper, thus actingon the tubes 0, O, and O thence up into the rear orifices of the fines entirely through said flues, and thence up and out through the smokestack. It is deemed important that the curved tubes C be arranged upon a circle concentric with the boiler, as shown, whereby they, to-
as and for the purpose set forth.
2. The combination, with a stationary horizontal steam-boiler provided with the horizontal flues passing through the interior of said boiler and connecting the heads thereof, of the spirally-arranged water-tubes extending transversely through said flues, for the purpose described.
In a stationary horizontal steam-boiler, the combination of the through-fines B, B, B and B the transverse spirally-arranged watertubes 1), extending through said fines, the semicircular tubes underlying said boiler and communicating with the interior thereof, and the horizontal tubes interposed between and connecting said semicircular tubes, and arranged as and forthe purpose specified.
4. The combination, with the main body portion of a steam-boiler, of semicircular water-tubes underlying said boiler and concentric therewith, made up of sections coupled together, and the interposed horizontal tubes connecting said semicircular tubes, all substantially as described.
In testimony whereof I atiix my signature in presence of two witnesses.
JOHN WAYMAN.
