Damper-Attachments for Furnaces.

Q zNviNTo UNITED STATES PATENT Orrron EDWARD P. BATES, OF SYRACUSE, NEW YORK, ASSIGNOR OF ONEHALF HIS RIGHT TO WILLYS H. WARNER, OF NEW YORK CITY.
IMPROVEMENT IN DAMPER ATTACHMENTS FOR FURNACES.
Specification forming part of Letters Patent No. 152,032, dated June 16, 1874; application filed April 7, 1874.
'To all whom it may concern:
furnaces and consists in a novel. construction, combination, and arrangement of parts, which have for their object to direct, regulate, and control the current of heated air or gas issuing from the furnace, and extract the heat therefrom, and render it applicable to use for power or warming purposes, 850., without afl'ecting the draft of the furnace, as will be fully set forth hereafter.
The drawing represents a vertical longitudinal section of the apparatus.
A represents a bench of gas retorts for making ordinary coal gas. a is the retorts, and b the furnace. The heated air and gases, after passing around the retorts as usual, enter the flue B, which proceeds to a chimney, G, for conveying the gas away. This current of heated air or gas, if allowed to escape directly from the flue B into the chimney O, and thence to the open air, is wasted. Iprevent this waste by extracting the heat before the gas reaches the chimney O; and, to accomplish this, the gas is in'terrupted in its passage along the flue B, and directed through the flue D to a steamboiler, E, through which it passes, its heat being extracted by the water. The gas, thus cooled and deprived of its heat, passes into the chimney O, and into the open air, as usual.
To regulate, by the steam -pressure, the supply of heated gas to the boiler, I employ two dampers, one, 0, situated in the retortfurnace fiue B, between the chimney O and the flue D, leading to the boiler; and another, 61, situated in the flue D, leading from the furnace-flue to the boiler. These dampers are suspended to a vibrating arm, 0, which is operated by the pressure-diaphragm g, through the rod f. 7
On the pressure in the boiler becoming excessive, the diaphragm expands and actuates the lever e, and operates to close the damper in the flue leading to the boiler, and open the one in the flue leading to the chimney, thus diminishing the supply of gas to the boiler. A decrease of pressure in the boiler will efl'ect an opposite movement in the dampers, and directs the current of gas through the boiler. I
The direction of the current with steam up and down is clearly shown by the arrows in the drawing.
From the foregoing it will be seen that, by means of the flue D and dampers c d, I can pass the heated gas or air through the boiler E, and regulate the flow of heat through it without afi'ecting the draft of air to the fur naoe b, which must be kept atastationary tem perature and rate of combustion.
It is evident that if there were but one flue, B, issuing from the furnace b, and this passed-directly through the boiler, any at tempt to regulate the flow of heat to the boiler would affect the draft to the furnace b, and there would be no means of shutting off the supply of heat to the boiler E but by entirely closing the flue B, thus extinguishing the fire in the furnace; but, by a modification of my invention, two flues may issue from the furnace, one passing through the boiler to the chimney, while the other enters the chimney directly. These, being provided with regulatirig-dampers, would accomplish the desired result-21 e., the regulation of the flow of heat through the boilerwithout aiTecting the draft to the furnace but this I consider simply an embodiment of my invention in another form.
I am familiar with the Letters Patent Nos. 32,559, 93,104, 99,153, and 27,530, and disclaim the inventions therein described.
I claim- The combination, with the furnace b and flue B, of the supplemental flue D, boiler E, and dampers c d, one working in each flue, and operated by a pressure-diaphragm, whereby the heat issuing from the furnace b may be deflected in variable quantities through the boiler E, or passed entirely and directly to the chimney 0, without afl'eoting the draft of the furnace, constructed and operating substantially in the manner described and specified.
