UNITED STATES PATENT OFFICE.
ROBERT EXCELL, OF CHICAGO, ILLINOIS.
IMPROVEMENT IN BOILERS.
Specification forming part of Letters Patent No. 186,083, dated January 9, 1877; application tiled November 11, 1876.
To all whom it may conce-rn Be it known that I, ROBERT EXGELL, of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Boiler, of which the following is a specification:
In the accompanying drawing, Figure l represents a vertical longitudinal section of my improved boiler on line y y, Fig. 2. Fig. 2 is a top view, and Fig. 3 a vertical transverse section ofthe same on line .fr .00, Fig. 1.
Similar letters of reference indicate correspondin g parts. v
The invention has reference to an improved tubular saddle-boiler for heating greenhouses and for other purposes; and it consists of a semicircular boiler with longitudinal ilues arranged therein, in connection with a lateral fire-back at the bottom, and a lateral circulator at the top part of the boiler, between which the lire passes from the fire-place back to the lines. The boiler communicates by top-flow tubes above the circulator and' return tubes at diagonal ends with the heatingtubes.
In the drawing, a represents a semicircular or saddle-shaped boileil which is supported on suitable side walls, and a lateral wall at the end of the fire-place. The boiler is of such thickness that a single row of heating-dues passes longitudinally through the same to conduct the iiregases through to the chimney.
rIhe shell of the. boiler is made so close to the iiues that not more than a space of about three-fourths of an inch is left between the sides of the boiler and the tlues, so that the boiler-shell contains as little water as possible, and a large heating-surface which proi motes a rapid circulation of the water for heating purposes.
The water tlows out of the boiler to the system of heating-pipes by top tubes B that communicate with a lateral bridge or circulator, C, at the inner top part of the boiler. The
water returns in cooled-oft' state through the pipes B at diagonal ends of the boiler after having passed through the heating-pipes.
Below the bridge or circulator C is arranged generator D, that leaves a contracted space between the same and the top bridge C above for the passage of the lire. The water is heated up rapidly in the bridge and lire-back, so as to impart a certain impetus to the water and force it into the top pipe with considerable power. The lireback, as well as the bridge, is rounded oli` to admit the ready passage of the tire. The fire-back serves in similar manner as the bridge for heating up and circulating the cooler water at the lower part of the boiler, so as to drive it up to the upper circulator, where it is exposed to the greatest degree of heat, and then forced to circulate through the system ot' pipes.
Suitable pockets at the lower part ot' the boiler serve to clean the same from time to time of' the sediment deposited by the water at the bottom parts.
As the fire-place is below the front part of the boiler, in front ofthe bridge and generator, the heat of the lire is first exerted on the front section of the boiler, next on the circulator and generator, then on the rear part of the boiler, and finally by the passage through the lues, utilizing thereby completely the heating capacity ot' the re, so that an economical and effective boiler for hot-water circulation and heating purposes is obtained.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The boiler A, having an arched series of tire-places at the top and sides, the circulator C and generator D near the middle, and pipes B B connecting with heater, all substantially as shown and described.
ROBERT EXCELL.
