IMPROVEMENT IN GLASS-FURNACES.
Specification forming part of Letters Patent No. 200,973, dated March 5, 1878; application filed February 13, 1878.
To all whom it may concern Be it known that I, JAMES M.BROOKFIELD, of Brooklyn,in the county of Kings and State of New York, have invented a new and useful Improvement in Glass Furnaces, which improvement is fully set forth in the following,
specification, reference being had to the accompanying drawing, in which- Figure 1 represents a longitudinal vertical section of a furnace embracing my invention. Fig. 2 is a horizontal section thereof in the line as m, Fig. 1.
Similar letters indicate corresponding parts.
My invention is especially adapted to that class of furnaces having a tank to receive the substance to be fused or molten.
In this class of furnaces it is common to form an airrpassage in the sill or partition between the fire-place and the tank, for the purpose of cooling the partition, and to introduce an air-blast through the ashpit, also sometimes called the Wind-box,for the purpose of accelerating combustion, the air-passage bein g supplied with air or other cooling medium independently of the ash-pit.
The object of my invention is to permit of using a single blast of air in cooling the sill or partition and driving the fire.
To this end it consists in combining, with the aforesaid sill or partition and the ash-pit, a wind-box or chamber, which is formed beneath the sill or partition, and communicates with the ash-pit, so that if air is introduced to this wind-box or chamber it circulates through the same, and thence passes into the ash-pit.
In the drawing, the letter A designates the tank of my furnace, constructed with a plain bottom; and B is the roof of the tank, having a solid form. a a are working-holes, through which the raw material is introduced, gathered, &c., and whichallow the products of combustion to escape. G is thefire-place, communicating with the tank by means of a passage, b. D is the grate, and E is the ash-pit or space beneath the grate. c is the sill or partition between the the place 0 and the tank, and which, in the example shown, is curved. Beneath this sill or partition 0 in the brick-work or other material of which my furnace is built, I form a closed box or chamber, F, which, in the example shown, is arranged to be connected with a fan-blower or other air-forcing device by means of a pipe, 01, and communicates with the ash-pit E through holes e formed in the wall, by which said box or 'chamber and the ash-pit are divided from each other.
The air supplied to the box or chamber F circulates through the chamber, so as to effectually cool the sill or partition 0, and then passes into the ash-pit E through the holes 6. The durability of the furnace is thus increased, with a great reduction in the expense and trouble attending the attainment of the like object in the old class of tank-furnaces.
Instead of connecting the chamber F with a fan-blower, atmospheric air may be allowed to enter thesame by its own pressure; and it is obvious that I can also use steam instead of air.
I claim as new and desire to secure by Letters Patent- In a glass-furnace, the combination of the wind-box F, arranged in the rear of the ashpit, and communicating therewith through the passage 6, and the pipe d, projecting outward from said wind-box, substantially as and for the purpose set forth.
In testimony that I claim the foregoing I have hereunto set my hand and seal this 8th day of February, 1878.
JAMES M. BROOKFIELD.
