HEATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 660,357, dated October 23, 1900.

Application filed January 9, 1899. Serial No. 701,652. (No model.)

To a/LZ whom it may concern:

Be it known that I, HIRAM BARBER, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Heating- Stove, of which the following is a specification.

My invention relates to improvements in heating-stoves in which a combined crosspartition and register is located above the grate, the object being to procure combus- Lion of gases. 'An air-shaft is also provided to afford a safety-duct through the cross-partition to prevent the escape of coal-gas into the room. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a sectional View of my device, showing the interior arrangement of the cross-partition and register composed of the plates P and R, the air-shaft A, and grate G.,

Fig. 2 is a plan view of the register composed of the plates P and R when openthat is, with the openings 0 and 0 coinciding-and showing also the upper end of the air-shaft A. Fig. 3 is a plan view of the register when closed.

In the construction of my heating device it will be observed that I make use of the plates P and R, which in combination form-a crosspartition and registerlocated above the grate G. The distance between the grate Gand the cross-partition is sufficient toafford a suitable chamber for the combustion of fuel. The partition-plate P is provided with the openings 0, which are preferably arranged in a semicircular form. Superincumbent upon the partition-plate P is placed the register-plate R, which is also provided with the openings 0,arranged in semicircular form to correspond with the openings 0 in the partition-plate P. The register-plate R is also provided with the handle 72, which operates in the slot S, provided in the casing K, and which slot is so arranged as to permit rotary motion of the register-plate R and is of a sufficient Width to permit the opening or closing of the openings 0' in the partition-plate P by the registerplate R. The partition-plate P is located a sufficient distance from the top of the" stove to afford a secondary combustion-chamber above the partition-plate P for the complete combustion of the gases arising from the fire v below the cross-partition when the degree of heat is sufficient to ignite the same in their passage through the openings 0' and 0.

'The door (1 is provided for the removal of the debris arising from the combustion of fuel upon the grate G.

When fuel is ignited upon the grate G and the openings 0 and 0 are coincident, the gases arising from combustion ascend through the passage formed by the openings 0 and o and thence out through the pipe X. When, however, the apertures 0 in the partition-plate P are closed by the register-plateR, the only exit for the gases arising from the combustion of fuel upon the grate G is the air-shaft A. The air-shaft A is never closed, and there is always, to some extent, a flow of heated gases upward through the same. The line of draft to the same from the ignited fuel located upon the grate G is, however, oblique and not as forceful as the'direct-ascending draft through the passages formed by openings 0 and 0. The air-shaft A is of such size and capacity, proportioned to the size of the stove, as to afford a safety escape for the excessive accumulation of gases. The advantage of this arrangement as embodied in my device is twofold. When the register is closed, the airshaft always affords a safety exit for the ac- 5 cumulated coal gas from the combustionchamber below the partition. This arrangement obviates the danger usually incident to the escape of coal-gas and is a safeguard against carelessness in operating the register- ICO plate R-a constant menace to the occupants of rooms heated by stoves. When the register is closed, the ascending or direct upward draft from the fire is cut off, and the draft is i in thereupon converted into an oblique or horizontal draft from the surface of the fire to the lower end of the air-shaft A and the lowest possible support given to the continued combustion upon the grate G consistent with safety to the occupants of the room heated by the stove; or, in other words, when the register is closed the least possible amount of fuel is consumed upon the grate Gconsistent with the safety of the occupants of the room heated by the stove. Economy and prudence are thus happily combined.

Having thus explained the mode of construction and the nature and object of my invention, what I claim as novel, and for which I seek Letters Patent, is the following, to wit:

1. In a stove, the combination with the easing of a combined register and cross partition above the grate, a door in said casing below said cross-partition, means for opening and closing said register, and an air-shaft ex tending downward from said cross-partition and forming a safety-duct for the escape of excessive accumulation of gases from the coal-combustion' chamber and adapted to moderate the combustion of fuel by inducing an indirect or oblique draft, substantially as described.

2. The combination with the casing K, of the register formed of the plates P and R which are provided with the openings 0 and o, thejiandle h to operate said register, and the air-shaft A, substantially as and for the purpose described.

3. The combination with the casing K, of the grate G, a cross-partition above the grate and formed of the plates P and B which are provided with the openings 0 and 0 and adapt ed to be used as a register, the handle it to operate said registerand the air-shaft A, sub stantially as described.
