IMPROVEMENT IN EOT-AIR FURNAGES.

4 A e il 'ro ALL WHoM I'r MAY coNcnnN:
Be it known that I, JONATHAN Amour, oilWest Roxbury, in the county of Norfolk, and State of Massachusetts, have in-vented`a new and useful Improvement in Hot-Air Furnaces; and I do' hereby declare the following to be a full, clear, and exact description of the same, rcference'being had to theaccompanying drawings, making a part of'this specification, in which- Figure 1 is a vertical section on line a of fig. 2.
Figure 2 isa horizontal section ou line c d of iig. 1.
Figure is a vertical section on line-efoi` g.1; and Figure ieisa vertical section line g h of g. 1. 4 The same letters refer to the'same parts in all of theigures. Y My invention relates to the manner of combining and arranging the several parts of a furnace so as to accomplish .the most economical combustion ofthe fuel, and also aiord capacity vto heat or warm a great volume of air te the proper temperature, so that the air shall not be overheated and rendered unfit for respiration.
To accomplish the first-named object, I employ, in combination with the fire-chamber of the furnace, a combustion-chamber, provided with hollow curves, similar to those described in Letters Patent granted to me April 5, 1859, and numbered 23,650, by means of which the unconsumed gases escaping from the tire-chamber are mixed with hot air und their combustion completed; and,`also, with aseries of vertical heating-pipes which traverse this chamber and are heated by the hot gases after they pass thecurves, by means of which a great extent of-heating-surface ispresentcd to the air, and an active circulation is maintained past the heatingsurfaces,`so that the excessive overheating of the air is avoided. i
In the drawings, A A represents the brick-setting, and B the lire-chamber. G C C is the combustionehamher, iitted to the top of the re-chamber, and supported on the brick walls at either end. It is provided internally with the hollow curves D D and E E arranged near the line leading from the fire-chamber, and also with the two series of tubes F which traverse the chamber vertically between the curves and the end of the said chamber, and through which the nir passes (to heat the same) to the upper side of tho combustion-chamber. E H are smoke-dues, from which the smoke is conducted to the chimney in any usual manner. The hollow curves DD are placed transversely across the combustion-chamher, one on either side of the outlet from the fire-chamber, and with their convex sides towards the same, and the curves E E are placed parallel to D D, and with their concave sides towards the same. These curves are made of the form shown, of common sheet iron, und hollow, and provided with small orifices, ,m m, from which the air, heated by its contact with the curves, is discharged among the' gases that' escape from the rire-chamber before being consumed, and,-being .thoroughly mixed therewith, the combustion of said gases is completed. The curves are supplied with air from the lower air-chamber, through the orifices I I and pipes G G, as shown in the drawings. lhe vertical heating-pipes F nearly fill the spacebetween the curves E E and theends of the chamber, and as the'capacity of that space to discharge a volume of gas is much greater than the iluc-space past the leurres, the hot gases are very much retarded and thrown into convolntions among the pipes, thus heating them'equably, and withoutdanger of overheating or destroying them, so that thin'iron pipes may be used, which will transmit the heat with greater rapidity than the thicker heating-surfaces commonly used.
The cold airis admitted to the hot-air chamber through the briclbwork near the bottom of the furnace, in the usual manner, and as it is heated it rises, coming in contact with the exterior of the fire-chamber and combustion-chamber, while a large portion oi' it passes, through the series of tubes F, to the top of the enclosed space, and is drawn olf as needed to warm rooms7 in the usual manner.
i What I claim as my invention, and wish to secure by Letters Patentis The combination of the hre-chamber B', the combustion-chamber C, the curves D and E, and the heatingtubos F," constructedv and arranged substantially as described.
Executed at Bostomthis seventh day of February, 1868.
