GLASS FURNAGE. No. 4,783. Patentedl Oct. 3, 1846.
UNTTED sTATEs PATENT oEEicE.
DEMING JARVES, OF BOSTON, MASSACHUSETTS.
GLASS-FURNACE.
Specification of Letters Patent No. 4,783, dated October 3, 1846.
T0 all whom t 'may concern.'
Be it known that I, DEMING JARvEs, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Glass-Furnaces, by which they may be operated by anthracite coal.; and I do hereby declare that the nature of the same is fully set forth and represented in the following specification and accompanying drawings, letters, figures, and references thereof. I
Figure 1 of said drawings denotes a front elevation of my improved furnace, Fig. 2 is a vertical and central section, taken through the mouth of the melting pot, Fig. 3 is a horizontal section taken through the said mouth of the said pot, and Fig. 4 is a horizontal section taken through the chimney, and just above the reverberating dome or arch, to be hereinafter described.
An ordinary glass furnace, as commonly constructed, consists of a series of melting pots, arranged within a circular or other proper shaped chamber, and as near the outer circumference thereof as they can be conveniently placed, and around a fireplace or pit, made inthe central part of t-he iioor or siege of said chamber. The flame of the iire made in the said pit is reverberated or thrown directly upon those parts of the melting pots which are nearest to the fireplace, while those parts which are farthest from the fire and which are immediately adjacent to lthe side wall of the chamber do not receive its iniiuence to so great a degree. From this and various other causes it has been found either impossible or unproiitable to use anthracite coal in such a glass furnace. The importance of a furnace, in which this kind of fuel can be used t0 advantage, will be apparent to every glass manufacturer.
In the aforementioned drawings, A represents a melting pot of the ordinary kind. Itis made to rest upon the top of a circular column orv siege B made of fire brick and extended above the Hoor C of the glass house, as exhibited in the drawings. The said column may have its foundation in or below the cellar or cave. D, E exhibits the fire grate, which, in this case, is made to extend entirely around the siege, and to rest upon the floor C, and over suitable openings F, F, &c., made through the floor, and so as instrument for stirring the fire and causingl the ashes to fall through the grates.
The iireplace or chamber Gr, is supplied with fuel through openings N, N, leading through the chimney and the reverberatory arch. The fireplace communicates with the chimney by one or more pipes or small chimneys O, O, which lead out of the chamber and into the chimney, as seen in the drawings. A part of the wall of theY Alire chamber, or that portion situated within the archway P, should be made so as to be read-x ily removed, whenever it becomes necessary to insert a new melting pot.
'The particular novel features of my improvement, consists in the manner in which the fire is disposed and made to act equally upon the sides and top part of the melting pot, the fuel chamber or fireplace being a circular chamber or space extending entirely around and below the siege of the melting pot; whereas, in common glass furnaces it is arranged at some distance from the re pot,
the iiame from it being reverberated or thrown against that part of the pot nearest to it. It is very desirable that the exterior surface of the pot should be equally exposed to the action of the heat, otherwise, changes of temperature, sufficient to crack the pot, are likely to occur.
By my improved mode of making the furnace, the iame from the ireplace is made to completely encircle the melting pot. The4 depth of the chamber around the iirepot, together with the position of the tease holes or passages N, 4N, enable me to fill the said chamber almost to the top with coal. Thus I cam embed, as it were the whole melting pot in a mass of coal, in combustion, and, by so doing, use the anthracite coal to great advantage.
What I claim, as my invention 0r improve- In testimony whereof, I have hereto set ment, is, my signature, this thirtieth day of May 10 Extending the fireplace and flame cham- VA. D. 1846. ber, entirely around, and so as to encompass 5 the melting pot, in the manner substantially DEMING JARVES as above described, instead of placing the Witnesses: fireplace entirely on one side of the pot, as R. H. EDDY,
is the custom in Ordinary glass furnaces. v CALDE EDDY.
