Description
UNITED STATES 'r QFFIGE.
JoHN HUGHES, on NEW YORK, N.
IMPROVEMENT IN STEAM-BOILERS.
Specification forming part of Letters Patent No. 193,253, dated July 17, 1877 application filed June 15, 1877.
To all whom it may concern:
Be it known that I, JoHN HUGHES, of the city, county, and State of New York, have invented a new and useful Improvement in Steam-Boilers, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure 1 represents a transverse vertical section. Fig. 2 is a longitudinal vertical sec tion in the plane 00 m, Fig. 1. Fig. 3 is a horizontal section in the plane y 3 Fig. l.
Similar letters indicate corresponding parts.
For many purposes horizontal boilers of cylindrical form, or of a form approximating thereto, are preferable, but are objectionable in some instances on account of their horizontal flues; and the object of my invention is to provide an approximately cylindrical boiler with vertical flues, thus combining the advantages of a vertical and horizontal cylindrical boiler.
To this end my invention consists in the combination, with the shell of the boiler, of p a tube-sheet on the top, and a series of vertical tubes extending from the crown of the firebox to said tube-sheet.
In the drawing, the letter A designates the fire-box of my steam-boiler. In the bottom part of this fire-box is situated the grate B, to which access is had through the fire-door O. In the convex top of said fire-box is a square, round, or oblong opening, a, over which extends a tube-sheet, b, which is secured to the convex top of the fire-box by rivets c.
D is the shell of my boiler, the top of which is made cylindrical, while its sides and ends extend down over the fire-box, and are connected to the same by stay-bolts d. In the top of said shell is an opening, e, correspond ing in shape and size to the opening a in the top of the fire-box, and over this opening extends a tube-sheet, j, which is fastened to the convex top of the shell by rivets g. In the tube-sheets b and f are secured a series of vertical fire-flues, E, and over the upper tubesheet f is placed the smoke-stack F.
It will be seen from this description that the firebox, as well as the fire-flues, are surrounded by water, and consequently a very tops of the fire-box and of the shell are strengthened, and my boiler is enabled to sustain a considerable pressure.
What 1 claim as new, and desire to secure by Letters Patent, is-
The combination, with the shell of a cylindrical boiler, of the tube-sheet secured to said shell, and a series of vertical tubes extending from the crown of thefire-box to said tubesheet, substantially as set forth.
In testimony that I claim the foregoing I have hereunto set my hand and seal this 12th day of J une, A. D. 1877.
JoHN HUGHES. [L. 8.].
