l HOT-AIR EURNAQE.
Specification of- Letters Patent No. y75,3()9, dated September 25, i847. i
To all whom t may concern.'
Beit known that 1,"WALTER BRYENT, of Boston, in the county of Suffolk, and'State of Massachusetts, have invented new and usefullmprovements in Hot-Air Furnaces, and that the following description, taken in connection with the accompanying drawings, hereinafter referred to, forms a full and exact specificationof the same, wherein I have set. forth the nat-ure and'principles of my said improvements,'by'which my invention maybe distinguished from others of asimilar class, together with such parts or combinations as I claim land 'desire to have' secured to me' by Letters Patent.
The figures of the accompanying plate of drawings represent my improvements in connection Vwith adfurnace now in common use in this vicinity.
Figure l, is a front elevation. Fig. 2, is a vertical section taken in the yplane of the line A, B, Fig. 3. Fig. 3, is a plan with the two plates a a. b b Fig. 2, removed. Fig. 4, is a horizontal section taken in the plane of the line C D Figs. 1 and 2; and Fig. 5 is a detail view, representing a modification o one portion of my improvements.
E E E, Sac., Figs. l, 2, 3, 4, is the exterior wall or casing of t-he furnace, const-ructed in the usual way with proper openings for the introduction of the external atmosphere to the cold air-chamber F F F, Figs. 2, 3 and 4, which chamber is comprehended between said wall E E, Sac., and the partit-ion G G G G. Near the bot-tom of the last named partition, suitable rectangular openings u, u, u, Fig. 2, are formed, through which the cold air is received to the hot air chamber or space H H H, &c., about the fire-pot I, and smoke drum K K.
L, L, L, are the hot air pipes for conducting the heated air to the various apartments of the building.
M is the throat of the fire-pot and N Fig. 1, the door of the samepthrough which the fuel is introduced. 1
O is the grate of the fire'pot, which is of the kind usually known by the name of the pendulum grate, andy P is the ash-pit.
The several parts above enumerated together with their usual appendages, which are represented in the drawings, are constructed mainly in a manner, now commonly known to mechanics versed in such matters, and need not therefore be more particularly described.
lMyfrst improvement is however in the lire-pot, and i'tconsists '1n combining orcasting on the external surface of the same, ad-
ditional material in such shapes or yforms as to .radiate or conduct olf, with the most facility the heat'from the sides -or periphery#l of the lire pot and in such a. manner las to effectually prevent th-e cracking or breaking of lthesame whena large quantity of fuel is in perfect combustion therein. f This increased. and more krapid radiation, it should be observed, will also greatly` assist in heat' ing the air in the hot air chamber designed for distribution. This additional material 1s embodied in radial arms s s s s, &c., eX-
tending out as far vas is practicableinto the n hot air chamberH H H, and s'tudding the external surface of the fire-pot as thickly as Y,
Fig. 2, that is, as frusta of elongated cones, e ori in anyother form,so that they shall acpossible. "The'ymay be shaped as shown in complish substantiallythe same result of preventing breakage to the fire-pot and greatly enhance, ina manner, peculiar to this device of radial arms, the heating of t-he air that comes in contact with thes parts.
My second and morevimportant improvement, consists in insert-ing in the hot air chamber a peculiarly constructed vhollow radiator c c c, Figs. 2, 3, Ll, and COlIlbining the same with the smoke drum K K, so that the smoke and other heated products of combustion from the re pot, shall circulate through the said radiator before being discharged to the chimneyl and thereby materially assist in the process of forming hot air. This radiator is made hollow as shown in Figs. 2 .and 4t, the sides being bent into the shape ofv a segment of an ellipse, or so as to be nearlyconcentric with the periphery of the smoke drum K K, and the top, bo-tt-om and front ends d d, 3, being closed *Y 00 with plates secured tothe sides aforesaid in any suitable manner. On the top of this i radiator c e c are the three sm'oke pipes e .e-v`
f fg g, all of which branch from the short l vertical pipe hwhich sets into or over the neck on the top of the smoke drum K K. The pipe e e communicates with the interior of the radiator at the rcenter of the back of i is a partition i z', Figs. 2 and `3, extending to l about one-half the depth of the radiator, in I order to cause'the smoke, &c., to circulate throughout the space inclosed within said radiator. There is aturning valve or damper lc" in the pipe e e` as shown'bydotted lines f 1 in Fig. 3, which is operated by the arm ZHZ extending out to the front f thefurnace, and when this damper is closed the smoke,
&c., passes from the smoke drum K` Kl through the pipes f g and radiator c c @,as shown by arrows inyFigs. 3 and 4;.
This radiator like all othersl as is well` known will become fouliand clogged by soot, &c., from time to time, and in ordertov` clear itV out, there are two pipes m m,m m. with closed fronts which communicate with; theradiator at the bottom of the front ends `of the same, as shownl in Figs. 2 and 4.`
These pipes are inserted from therfront ofj vthe furnace on eachside of the same as shown in Figs. l and 4, and when they are` removed a brush on the end of a` wire mayl be passed into and throughout the radiator and clean out the soot, &c., withl great fa-V cility.
Fig. 5 exhibits a slight modification of the. mode of communicatingbetween the smokev drum K K and the radiator, o c c, there being but two wide rectangular pipes '20, g, which are situated as shown in Fig. 5 and communicate from about the center of the `o'uishing characteristics of drum to the center of the: sides of the radiad tor,.andbeing soarranged they serve to cir- The radiator o c o, constructed for the circulation of the smoke, &c., throughout its ine-` terior and arranged for the removal-of soot, &c., from the same substantially as herein above described, and alsothe combination of such a radiator with the smoke drum of the furnace substantially as above set forth.
In testimony that the foregoing is a `true description of my said invention and improvements I have hereto set my signature this eighth day of March, A. D. 1847.
