SPECIFICATION forming part of Letters Patent No. 409,036, dated August 13, 1,889.

sein Nq. 266.152. (Np man.;

To all whom it may concern: Be it known that I, LEWIS W. IIAGEY, of 4th'ecity vof St. Louis, in the State cf Missouri, have invented a certain new and useful Im- '5 provementin l-Ieating-Stoves, of which the following is a. full, clear, an'd exact description, reference being had to the' accompanying drawings, forming partof this specification, andin whichv-v Figure I 'is a front view of .a horizontal stove, showing the f projecting horizontal damper, with part broken away-to show the lining audits bevel coping that prevents the entrance of ashes Within the intermediate .dead-air chamber. Fig.'II is a vertical section of the stove, taken on line II Il, Fig. l, and shows the interior of the stove, its lining, and dead-air chamber, with its projecting -horimatal damper inprdlile. all CIL- ze larged vertical section-ofthe projecting horizontal dampentaken on line. Ill 1V, Fig. II, showing the damper open; and Fig. lV is a like view showing'the damper closed.

'lhis invention relates to a horizontal' heating-stove provided with devices for the econ.- omy of fuel, and havinga draft adjustment comprising a projected horizontal damper that is located at the' front end of the ,stove Y contiguous to `the bottom thereof beyond the adverse influence of the falling ashesg and the invention consists in features of novelty, hereinafter fully described, and peint-ed out in the claims. 1 Referring to the drawings,in' which'like figures of reference indicate similar partsin -all the views, 1 represents the horizontal body ofv one of 'my heating-stoves. The bottom 2 of said stove is preferably made of cast-iron, but may be, .like the sides 3, ends 3, and top 4, made of Russia iron or any other-,suitable sheet metal.-

l 'lhe intcriorofthe stove is provided with -a sheet-metal lining 5, which may ascend from the bpttom two-'thirds up the side of the stove,

more or less, and which may be either of llussia iron or other' suitable metal. This h mng is placed parallel to and at a suitable distance from the'outcr casing to provide a .dead-air chamber G in the intermediate space. io ,The-lining terminates at top in a bevel cop- 4lng 7, the. upper edge of which is attached to the outer casing of the stove, thereby preventing the entrance'into the dead-air chamber of ashes o icindei's, &c., from the interior' of the stove.

8 represents the projecting horizontal damper, which is constructed of an inner cyl-g inder 9, that passes clear through -thc casing, dead-air chamber, and liningmear the bottom of fthe front end of the stove, and is 6o held in its seat by its inner hanged periphery 9, that engages with the lining against which it fits.' The said inner cylinder is terminated externally by a disk 10, that both forms a cap .that closes in ,the end of the cylinder, and extending past said cylinder provides a peripheral flange 11, which holds to its seat the outer rotary cylinderplfl, which ts snugly and rotates around the inner cyl- Linder. In .the construction of the outer cyl- 7o meet at their circumferential junction areI Aflanged outwardly and riveted together, as shown in Figs; 1II and IV, and beneath the damper in Figs. I and Il, so as to form a handle 13 for. the movement of the operative damper around the inner cylinder.

A -U-shaped opening His cut in the upper part of the inner cylinder, anda like aperturel is cut in the outer cylinder at the far- 8o ther sidefroin the handle 13.

It is .evident that when the outer cylinder is in the position shown in Figs. I, II, and III, vwith its handle down, the U-shaped apertures of both` cylinders are in corresponding position, and' consequently the outer cylinderis p fully opened and letsfin afree full draft. 0ul l the contrary, when the` outer cylinder is in the position shown-,in Fig. IV, with the handle elevated toits full capacity, the draft will .9o

be entirely shut off, for the close semi-periphery'of the rotary outer cylinder then covers the aperture in .the inner cylinder. When, again, it is desired to partially close the damper, the rotary outer cylinder of said 95 damper isturned accordingly into an intermediatejposition.

eylindric damper projected horizontally entirely beyond the end'of the base of the stove in conjunction with the position of the draftopeuing thereto, and means of operating the inder-t'h'e eds or the'sheet'metaiwhere they It will be seen that by my device of a double y draft, means are provided for avoiding the choking of said damper by falling ashes from the fire, so as to always have when required a good and sufficient draft, and when it is desired to stop or nearly stop the combustion of the fuel the right adjustment of the telescopic double cylinder efficient-ly answers the purpose.

So as 4always to have more full control of thezdraft, no door is provided at the sides or ends of the stove, and consequently the draft can be shut off more eectually than. it could be from an57 stove that was furnished with a side or end door and consequent feed-opening. The stove, having no door at the side or end, is provided with a feed-opening 16 in the V top which, except when feeding, is closed by the cover 17.

Large blocks of wood and knots can be casily inserted through this opening in the top of the stove that it would be very diicult to insert through the usual feed-door, for the g1.'t vity of the feed assists its insertion from the top, but is obstructive to its passage through the usual doorway.

A small sliding damper 1S is inserted near the top in the front end of the stove. This damper usually remains closed, and is not intended, in the general Way, to provide inspiration to aid combustion; but when the projecting cylinder-damper is closed at night, or at any other time, and in consequence the rareied air in the stove expands faster than it finds vent through the flue 19, the upper sliding damper is opened to allow respiration to relieve the expansion.. Sometimes, also, it may b'e desired to open the other damper to furnish an upper draft that will not undermine the fuel and too rapidly enforce combustion.

Among other advantages in this stove is its economic use of the fuel, through the peculiar arrau gement of the cylindric damper,

and its easy adjustment relatively to a full, partial, or closed draft and its otherwise closed front, as it has no feed-door. These stoves now in use, when the cylindric projected damper is closed, have kept lire for forty-eight hours, so that when opened it freely burns again, saving the trouble of relaying the fire and saving the use of kindling. They will probably keep lire for a much longer period, if tried.

Another advantage of the free adjustment and peculiar varrangement of the draft is that the heat can be arrested from escape through the smokefues, for it is nearly Wholly economizeo. within the stove for radiation within the apartment to be heated, in consequence of the above-described devices.

I claim as my inventionl. In a heating-stove, the horizontal cylindric damper that projects in front of the stove near the bottom thereof, the outer cylinder having rotary movement around the inner one, and both cylinders being provided with U-shaped openings that are adjustable to regulate the draft, the outer casing, and lining to the stove that supports the damper, substantially asv and for the purpose set forth.

2. The combination of the stovebody 1,lin ing 5, and projecting horizontal damper located near the bottom of the stove, consisting of the inner cylinder 9, formed with inner peripheral flange 0 secured to the lining, the U-shaped opening, and cap 10, having outer peripheral flange l1 and outer rotating cylinder l2, fitting around the inner cylinder, and formed with jianged handle 13 and U-shaped opening, substantially as described and shown.
