DAVID WILSN AND WILLIAM B. HARTLEY, OF WASHINGTON, D. C.
IMPROVEMENT IN STEAM-GENERATORS.
Specification forming part of Letters Patent N0. 2l 5.421, dated May 13, 1879 application filed February 25, 1879.
To all whom it may concern.-
Be it `known that we, DAVID WILSON and WILLIAM B. HARTLEY, of Washington, in the county of Washington and District of Columbia, have invented certain new and useful Improvements in Steam -Generators; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the and it consists in the manner of removably 1ocatin g a tubular boiler inside of afurnace, and supporting it in its position there, and a fuelreservoir attached to a removable cover of the furnace, and extending downward through the tube of the boiler, and so constructed and arranged as to expose the whole exterior surface of the boiler to the heat of the furnace, as will hereinafter more fully appear; and it also consists in the construction of a check-draft located upon the top of the generator.
A represents a boiler located inside of a shell, B, and over the furnace. This boiler rests upon angle-irons C C, which are securely attached to the inner surfaces of the shell. The boiler is provided with a cover, D, which is attached to the shell by bolts d in such a manner as to be readily removed. To this cover D is attached a fuel-reservoir, HE, which eX- tends downward in a vertical direction, passing through the tube A of the boiler, and eX- tending somewhat beneath the same. E is a cover to this fuel-reservoir.
F is a rotating fuel-grate, supported by the curved arms g, which are attached to the firegrate G, which is supported by the angle-irons H, attached to the inner sides of the shell. I
is the furnace-door. Kis the ash-pan. L is the water-supply pipe. M are gage-cocks. M is a water-gage. N represents the safetyvalve, and P the steam-pipe. These pipes,to gether with the stems of the water-gages, Snc., pass through the walls of the shell to form connection with the boiler. cover of the shell are preferably of iron; but they may be made of any suitable non-combustible material.
B and R are check-drafts or da'mpers pivoted to the top of the boiler at r r', and so constructed as to conform to the fuel-reservoir E and cover the space between it and the boiler A. The rod S is connected with the` jointed bars Vs s, which, upon their opposite ends, are connected with the dampers R R', by which one or both of the dampers may be wholly or partially opened or closed by operating the rod S, which extends outside of the furnace.
U U are an ges attached to the boiler, for directing and controlling the heat of the furnace.
By means of our invention we are enabled to suspend a steam-generating boiler in the interior of a furnace in such a manner that the whole exterior portion of the boiler will be exposed to the heat, including the tubular portion of the boiler. Check-drafts may be located in the tubular portion, or between the exterior portion of the boiler and the walls of the shell, for regulating the heat of the furnace. are enabled to distribute the fuel by centripetal force evenly over the fire-surface.
We are aware that heretofore steam-generators have been constructed with a fuel-reservoir centrally located in them, and that steamboilers have been located inside of furnaces; but we are not aware that heretofore there has been any steam-generator removably located in the interior of a furnace in such a manner, and so constructed and arranged as to expose the whole exterior surface of the boiler, and provided with a tubular reservoir for fuel, eX- tending through it, removably attached by the cover of the boiler, and so constructed as to provide uniform expansion of metal, dura bility, and generation of steam.
The walls and By means of the rotating grate F we Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-
l. In a steamgen erator, a boiler constructed with a central flue, and suspended within the shell B in such alnanner upon supports C that there is a free circulation of the draft between the Shell and the boiler, and cover D, in con1- bination with a fuel-reservoir, E, which eX- tends down through the boiler-flue, and having a free draft-space between it and the boiler, substantially as set forth.
2. In a steanrgenerator, the shell B, provided with a cover, D, which is attached to thefuel-reservoir E, said reservoir extending` downward through the flue A of the boiler, which rests on` angle-irons C, and the compound rot-ary grates F and G, supported by DAVID WILSON. WILLIAM B. HARTLEY.
