STOVE FI RE-POT.
SPECIFICATION forming part of Letters Patent No. 347,995, dated August 24, 1886.
Application filed October 15, 1885. Serial No. 170,045. (No model.)
To all whom, it may concern:
Beit known thatwe, JOHN CLAPP and WILL IAM J. KEEP, of Detroit, in the county of Vayne and State of Michigan, haveinvented new and useful Improvement in Stoves; and we do hereby declare that the following is a full, clear, and exact description thereof,refer ence being had to the accompanying drawings, which form apart of this specification.
This invention relates to a new and useful improvement in lcoal-stoves.
The object of our improvement is to provide a more simple and ready means for cleaning the teeth of the fire-pot from ashes, and which will obviate the use of other means for that purpose; and theinvention consists in the peculiar combinations and the novel construction, arrangement, and adaptation of parts, all as more fully hereinafter described and claimed.
Figure l is a vertical central section through a stove constructed in accordance with our improvement. Fig. 2 is a perspective view of the lower fire-pot section of the stove. Fig. 3 5 is a plan of the fire-pot.
A represents a fire-pot, or that section of fire-pot which is immediately above the grate. B is the grate, and C is the inclosingshell, all the parts being of the ordinary form or construction, except as hereinafter specified. The fire-pot A has around its top or near it an loverhanging annular rim or flange, D, the under side of which is provided with a groove or channel, E, while the upper side is provided with a series of cogs, forming a gearwheel, l?. rlhe fire-pot A is movably supported upon rollers G, which are in turn supported upon suitable brackets secured to the walls of the stove. The rollers G travel in the channel E, which latter is preferably concave in cross-section, and wide enough to allow the jrire-pot a lateral play, there being a small annular space left between the rim of said tire-pot and the walls of the stove to admit of such play.
H is an annular flange depending from the shell of the stove. It is provided near its lower end with a ledge, l, which serves as a support for a lining, K, which may form the 5o upper part of the tire-pot. This ledge has upi wardly-projeeting lugs L, which enter corresponding recesses in the lower edges of the lining, and thusV prevent the same from accidental displacement.
M arelugs projecting downwardly from the depending flange H, and within close proximity of the rim of the tire-pot section A,thus serving as guides to prevent accidental displacement ofthe same.
The throat N, which forms the interval be- 6o tween the rotary tire-pot A and the stationary tire-pot section or lining K, is narrow on the inside and widens toward the outside, so as. to form an easy escape for any material which may find a lodgment therein. To prevent the ashes escaping through this throat from falling against the windows, the latter are protected by deflecting flanges O.
l? is a pinion arranged to mesh with the gear F. It is secured to a shaft, R, for which 7o the depending flange H and the adjoining wall of the stove form suitable supports,while the pinion itself is protected thereby and can revolve freely in the intervening space. The outer end of the shaft R projects through the shell of the stove, and is provided with a detachable handle, S, by means of which mo tion can be communicated to the pinion.
In practice it will be seen that by turning the handle S to the right or left the tire-pot 8J A will bc rotated upon its axis. As the coal iu the stove is mainly supported upon the grate, it is obvious that if motion is thus given to the movable part of the fire-pot the result will be that only the outer portion of the fuel in the same will be disturbed, and if this is wholly or partly composed of ashes the latter will be dislodged and drop out, al-
lowing the fuel at the same time to spread and ll the vacant spaces. Thus theincandescent 9o coal in the lower part of the fire-pot is made visible through the teeth of the iire-pot and through the open space between the fire-pot and the top of the grate.
It is a well-known fact that the coal which lies close to the teeth of the pot is consumed faster than the coal in the center, and as our device in removing the ashes naturally induces a corresponding feed of fresh coal, it becomes at the same time au auxiliary mechanical ioo feeding device,which is better calculated than any other means now practiced to maintain a clean and bright fire in the whole fire-pot with the utmost economy of coal, and we wish it to be understood that we claim our improvement for such purpose alone.
The object of allowing the fire-pot a limited lateral play is to render it less liable to be wedged tightby obstructions, while by'nlaking the channel E concave the fre-pot has the natural tendency to keep in its prescribed position when free to do so.
Although we have shown our improvement in connection with such section of fire-pot, which is immediately above the grate and provided with teeth,we do not want to be understood as limiting ourselves thereto.
The specific application and arrangement shown and described is preferab1e,in so far as it combines all the advantages set fort-h, and has the attendant advantage that thc parts which give motion to the fire-pot are well protected and are not liable to become inoperative, while at the same time the arrangement is si mlple and requires but little power to operate it.
What we claim as our invention is 1. The rotary fire-pot A,having the laterallyprojecting flange D,provided on top with the gear F and on the under side with the concave channel E, in combination with the supporting-frame of the stove provided with the rolling supports G, and the actuating-pinion B, substantially as described.
2. The combination, with the Supportingframe of the stove, of a fire-pot composed of a stationary upper section and a rotatable lower section, the stationary section being supported on a depending flange from the wall of the stove and the lower section upon rolling supports, and provided with annular groove, and l thev guides M on said upper section, substantial] y as described. v
3. The combination, with the rotary fire-pot A, having the ilange or rim D, and the shell provided with windows,of the defiectors O on the inside of said shell over the windows, substantially as described.
4. A rotatable fire-pot having downwardlyprojecting teeth at its lower end, means for supporting said fre-pot,a laterally-projecting flange on said pot provided with cogs, the wall of the stove, a depending flange from the said wall for supporting a lining, and a pinion engaging with the cogs and having its shaft supported by the depending flange and the wall of the stove, substantially as de-v scribed.
