Description
UNITED STATES HUGH LESLIE, OF JERSEY CITY, NEW JERSEY.
IMPROVEMENT IN STEAM-BOILEHS.
Specification forming part of Letters Patent No. 13A l 7, dated July 5, 1364.
To @ZZ whom, it may concer-n,.-
Be it known that 1, HUGH LESLIE, of J ersey City, in the county of Hudson and State ot' New Jersey, have invented certain new and useful Improvements in Steam-Boilers; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to fully understand and use the same, reference being had to the accompanying drawings, making a part ot' this specification, in which- Figure lis a side sectional elevation of a marine boiler; Fig. 2, a plan or horizontal section of the same; Fig. 3, a side elevation of a stationary boiler; Fig. 4, a plan or horizontal section of the same.
My improvement is applicable to the construction of marine and land or stationary boilers, and the exterior form of my boiler is intended to be the same as those in general use..
rfhe ash-pau to be used under the boiler and the smoke-stack or chimney over the boiler are made and applied in the usual manner.
The method of constructing, riveting, and combining the various parts to be hereinafter described is also the same, except as otherwise specied, as that commonly practiced in boiler-making and no especial description thereof is here required. The same remark applies tothe staying or strengthening of the boiler by interior braces, which may be applied wherever the maker deems necessary.
Ais the outer shell of the boiler; B, the inner shell; C, the crown-sheet; D, the firechamber, E, the steam-space 5 E', the waterspace.
Aprominent feature of my improvement consists in the employment of a series of iudependent tubes, F, suspended fromthe crownsheet C, and projecting downward therefrom into the lire-chamber D, substantially in the manner shown. The lower ends of these tubes are closed. The upper ends are made slightly conical or aring in form and iit into corresponding conical apertures or holes made through the crown-sheet. The tubes thus tted willbe kept tightlby the downward pressure of the steam, while they may be at any time easily removed for cleaning or the replacement of defective tubes.
So long as the water covers the crown sheet the tubes will always be filled, and as the tubes project into the irechamber and receive upon them the direct action of the tire they will greatlyassist to promote the rapid evaporation of the water.
Between the inner and outer shells, A'B, at the back part of the rechamber, I arrange a series of smoke flue-tubes, G, and at the back part of the boiler, running entirely through the same from top to bottom, I arrange another set of smoke-tlue-tubes H, substantially in the manner shown. The bottom of the boiler stands upon a suitable ashpan, and the tubes H are covered by a suitable smoke-stack or chimney.
The course of .the products of combustion is represented by the arrows. After acting upon the tubes F the heated products pass downward through the ues G, along the under side of the boiler, within the ash-pan, to the bottom of the tubes II, through which said products then rise and pass out into the chimney.
The tubes G and II are intended to be constantlysurroundcd with water andthe passage ot` the heated products of combustion through them assists to promote the evaporation of the water. The upper ends of the tubes H pass through the steam-space and promote the drying of the steam, all in the manner well understood by persons skilled in the art.
In the application or use of the independent tubes F, I do not limit myself to any precise number or size, nor to any particular arrangement or location thereof within the boiler. y
In the use of tube E, I believe that an important advantage is gained over ordinary steam-boilers by securing a freedom from the danger of sudden or powerful explosion from the lack of water. Should the water in the boiler from any cause fall below the crownsheet, the lower ends of the tubes F will soon be burned ott by the tire, when the steam y from the boiler will escape from the tubes F, 2. The eombi11ation,\\ith the said short-Hue extinguish the fire, and prevent further damtubes G ofthe flue-tubes H, extending through age to the boiler. the boiler, substantially in the manner and Having' thus described myiuventiom claim for the purpose herein shown and described.
as new and desire to secure by Letters Pateut- HUGH LESLIE.
l. In combination with the fire-chamber D,
the lues G, to conduct the products of lituessesa combustion downward, all substantially 21s JAMES P. HALL,
herein shown and described. A GEO. WV. REED.
