Letters Patent No. 93,764, dated August 17, 1869.
IMPROVEMENT FURNACES STEAM-GENERATORS.-
The Schedule referred to in these -Letters Patent and making part of the same.
To allrwhom it 'may concern:
Be it known't-hat I, Fnlnnmcl: SUI/run, ofSt. Paul, Ramsey county, and State of Minnesota, have invented Improvements in Furnaces for Steam-Gener-v ators, Sac.; and I hereby declare the following to-be an exact description thereof', reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in whichy Figure 1 represents a sectional elevation of the furT f nace, showing the adjustable regulator as operatingin the smoke-chamber in the rear of the furnace.
Figure` 2 also represents a sectional side elevation, with the regulator raised, showing "how it is adjusted up and down, to regulate the draught according to the kind of fuel used. f Y
Figure 3 represents a rearfend view of the furnace. Figure lLshows a cross-section of the fin'nace, with its cylinder and fines common to ordinary furnaces.
Figure. 5 represents afront-end view-of the furnace. The nature of my invention consists in the construction and arrangementl of the adjustable regulator in the smoke-chamber at the rearof the furnace.
The object ofthis regulator is to regulate the draught when different kinds of fuel are used.
When 'hard coal is used,- the regulator is raised, say about ltlnee-fourt-hs; when soft. coal or woodis used, the regulator is lowered, to allow the smoke or cinders to pass into the smoke-chamber, and be consumed.v
Hard coal making no smoke, and requiring a stronger draught, the regulator is raised to increase the draught,
(especially when the furnace is used with anold chimney in which the draught is defective,) and the heat is forced forward throughv the lowerl return-fines, alongside of the boiler, and then'into the upper flue, (containing the heater,) from which it passes out into-the chimney;
A represents the lire-box, from which the heat and cinders are carried `through the lower ue D, under neath the boiler B, the cinders being deposited in the smoke-chamber F, the heat thence passing along through a side-line, C, again to the front, thence upward to another flue, C', along the top side of the boiler, to the rear of the furnace, .and -thence out thc smoke-stack E, as indicated by the courses of `the arrows.
The smoke-chamber F-is located at the rear of the boiler, and has an inclined arch, K, extending from above the boiler to the opposite side` of the chamber,.
to prevent the smoke and heat from passing directly up through the smoke-stack, and to collect the cinders.
I- have two crank-shafts, G G, passing through the upper part of the smoke-chamber F, each shaft G having a chain, H, operating on it as a windlass.
Tothe lower ends of these chains H H, my regulator, J', is suspended.
The regulator J is made of sheet-iron, and fits closely into the smoke-chamber F, and is raised and lowered by means of the 'cranks G and chains H, for thepnrpose of increasing or diminishing the size ofthe chamher F,Ato increase or diminish the draught required, and is thus adj usted to suit the character of the fuel used.
. What I claim as my invention, and desire to secure by Letters Patent, is-
The crank-shafts G G, chains H H, and regulator J,-
when constructed, arranged, and operating in the smokechamber F, as herein described, and for the purpose set forth.
