PETER A. RENO, OF ST. LOUIS, MISSOURI.
SPECIFICATION forming part of Letters Patent No. 376,013, dated January 3, 1888.
Application filed January 25, 1887. Serial No. 225,453. (No model.)
.To aZZ whom, it vmay concern:
Be it known that 1, PETER A. RENO, of St. Louis, Missouri, have made a new and useful Improvement in Heatingrstoves, of which the following is a full, clear, and exact description.
The leading features of the improved stove are, first, an air flue or fiues whose inlet is at the front of the stove, and preferably as low, or thereabout, as the level of the stove-body, and which lead upward over or through the upper part of the fire-chamber, and then downward, and ultimately into the fire-chamber 'above that portion thereof occupied by the fuel; second, and preferably, in connection with said air-fines, and for providing an indirect draft, and also an auxiliary combustionchamber, a flue leading out of the fire-chamber and passing downward in front of but not, preferably, against the shell of the fire-chamber, to the level of the bottom of the ash-pit, under which it is carried, and thence upward at the back of the stove, but opposite the firechamber preferably not in contact with its shell; third, a fuel charger or magazine at the side or above the fire-chamber, and adapted to be rotated to discharge its contents into the fire-chamber, and made removable, so that it can be withdrawn or partly withdrawn from the stove when it is desired to replenish itwith the fuel.
The most desirable mode of carrying out the improvement is substantially illustrated in the annexed drawings, making part of this specification, in which Figure 1 is a side elevation of the improved stove. Fig. 2 is a front elevation. Fig. 3 is a rear elevation, the i'uel;charger being withdrawn. Fig. 4 is a vertical longitudinal section on the line 4 4 of Fig.3. Fig. 5 is a vertical transverse section on the line 5 5 of Fig. 1. Fig. 6 is a cross-section of the fuel-charger and its case, and Fig. 7 is a view in perspective of the fuel-charger.
The same letters of reference denote the same parts.
The stove A, saving as it is modified by the improvement under consideration, is of the customary form.
B represents the fire-chamber.
0 represents the grate.
D represents the ash-pit.
E represents the doorway to the fire-chamher, and F represents the escape from the stove. The air-fines are shown atG G, Figs. 1, 2, 3, 4, 5. In the present instance there are two of them, arranged, respectively, at the sides of the front of the stove, having the inlets g g, and extending upward to or toward the top of the stove, there uniting to form a single flue, G which extends over the fire-chamber and exteriorly thereto across the stove, then downward at G and leading intoth'e fire-chamber at 9", Fig. 4. The air without the stove passes into the fiues through the inlets g 9', becomes more and more heated as it passes through the dues, and is delivered into the fire-chamber at a level at which it can favorablycombine with the gases arising from the burning fuel; and to more effectively intermingle the air with the gases and smoke the air is delivered into the fire-chamber through a perforated plate or equivalent construction, H, Figs. 4, 5, whereby the air-current is divided into jets. The direct draft from the fire-chamber is, say, at I that is, upward through the air-flue G, .which is suitably constructed to provide for the direct draft. By means of a damper, i, the direct draft can be closed and the heat and gaseous currents directed into the flue J, which leaves the fire-chamber at j and passes downward in front of the fire-chamber and between the airflues G G to the bottom of the ash-pit, beneath which it is carried, and thence upward at the back of the stove, and it ultimately leads-to the escape F. The flue J is preferably made in a broad form, both to increase its radiating-surface and to provide more space within which the air coming from the air-fines can combine with the unconsumed fuel for the purpose of more thoroughly consuming it. The flues G GJ are preferably separated from the shell of the fire-chamber at K K, to increase the heatingsurface of the stove. The inlets g g to the air-fines are preferably toward the lower part of the stove, partly to promote the ventilation of the room and-partly to increase the efficicncy of the fines. The fuel-charger L is in the form of a drawer, semi-cylindrical in form, and adapted to be slid into a casing, Z, within the stove, above and preferably at the side of the fire-chamber. The casing has an' opening, Z, toward the fire-chamber, to enable the charger, after it has been inserted in the casing, to be turned around therein, as indi- IOC cated in Fig. 6, and discharge its contents into the fire-chamber.
I desire not to be restricted to any particular location in placing the fuel-charger in the stove. It may, for instance, be inserted at the front of the stove, and either longitudinally or transversely in the stove. In such case the other parts of the stove are suitably modified to admit of the charger being so located. By having the fire-charger at the side of the firechamber there is less liability of its contents coking than if it were directly in the line of the draft from the stove, and this end is further promoted by having the air-supply led past the position of the fuel-charger into the firechamber, as shown.
I claim- 1. In a heating-stove, the herein-described fuel-charger over the fire-chamber, said firechamber having an opening at its side,through which the fuel is delivered from the charger, substantially as described.
2. The combination, in a heating-stove, of the fire-chamber, the air-supply flue and the indirect-draft flue, and the perforated airinlet and the draft-outlet, the said inlet and outlet respectively being at opposite sides of the fire-chamber, as described.
3. In a heating-stove, the combination of the herein-described air-supply flue or lines leading from the lower front of the stove upward across the stove and above and exterior to the fire-chamber, and then downward into the firechamber, with the indirect-draft flue leading from the fire-chamber at a point opposite the air-inlet, downward at the front of the stove beneath the ash-pit, and upward at the rear of the stove, substantially as described.
4. In a stove, the semicylindrical fuelcharger L, combined with the casing Z, having opening Z within the stove, whereby the fuel can be discharged by turning the charger around.
\Vitness my hand this 14th day of January, 1887.
