IMPROVEMENT m GLASS-FURNACES.
Specification forming part of Letters Patent No. 130,154, dated August 6, 1872.
Specification describing an Improved Glass- Furnace, invented by FREnERIoK ROHRBACH- ER and FERDINAND HORMANN, both of the city and county of Philadelphia, State of Pennsylvania.
Improved Glass-Furnace.
laces and of causin a uniform and intense P 7 g heat to pervade the whole interior of the furnace, and to preserve from injury the contents ofsuch pots as may be broken.
In the accompanying drawing, Figure 1 is a vertical section of a glass-furnace with our improvement; Fig. 2, a vertical section on the line 1 2, Fig. l; and Fig. 3, a sectional plan on the line 3 4, Fig. 1.
A is the base of the furnace; B, the circular wall of the same; D, the roof or dome; and E,
the nose 6 of each pot projecting into a Work ing hole, f, and the opening of each pot being furnished with a cover, 2'. On the outside of the glass-furnace is built a fire place, G, furnished with the usual grate-bars H, this fireplace communicating, through a passage, h, and over a bridge-wall, n, with the interior of the glass-furnace, and having in front an openin g, m, for the admission of fuel. Within the glass-furnace, and separated by the walls at from the fire-place G, is built an air-chamber, I, communicating through a passage or passages, p, with a pit, J, formedbeneath the base of the furnace, and communicating with the interior of the furnace through holes or a, which are on a level, or nearly so, with the bench at. The interior of the furnace communicates with the stack F through the usual angular flues 3 formed at the edges of the working-holes f.
The products of combustion, after reaching the interiorof the furnace, are dispersed in every direction, and are consequently brought to bear on the whole of the pots in their attempts to escape to the numerous fiues 3 As the products of combustion, however, enter the furnace, they are met by numerous jets of heated air escaping through the openings at, and these jets of heated air tend to ignitethe unconsumed products of combustion, so that a clear flame of intense heat pervades the whole interior of the furnace.
The chamber 1 is supplied with air, through the passage or passages 10, from the pit J, which is made of considerable length in order to produce a draft, and as the air, before passing from the said chamber through the apertures as into the furnace, is considerably heated, it
will have no tendency to chill and crack the .pots. If a pot should become burnt out or broken, the molten glass from the same would flow through the apertures .12 into the chamber I, from which the whole could be withdrawn through an opening, 3 communicating with the cave, and the glass thus saved would be but slightly deteriorated, as the interior of the furnace can be kept comparatively clean and free from cinders.
We claim as our invention- 1. The combination, in a glass-furnace, of an exterior fire-place or fire-places and openin gs a, through which heated air is introduced into the interior of the furnace, substantially as described.
2. The chamber I, arranged above the ashpit and below the floor of the furnace, and communicating with the latter, as and for the purpose set forth.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
