Application filed February 19, 1887. Serial No. 228,239. (No model.) i

To all whom it may concern:

l 3e it known that I, WILLIAM J. KEEP, a cltrzen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a certain new and use-' ful improvement in Stoves, of which the following is a specification, reference being had therein to the accompanying drawings, in whieh- Figure 1 isaplan view of a stove constructed according to my improvement, with parts removed and the door and damper closed. Fig. 2 s also a plan with the door and damper open. Fig. 3is a back view of the stove, with parts broken away to show the damper in two positlons. Fig. 4 is a vertical central section of the flues. Fig. 5 is a detail of a dust-flue leading from the ash-pit to the smokeflne. Fig. 6 1s a perspective detail of the damper and rod. Fig. 7 is a detail,partly in section. Fig. 8 is a perspective view of partof the back of the stove, with parts broken away and other parts removed.

This improvement relates to various details in the construction of heating and cooking stoves, whereby said stoves are rendered more useful and convenlent; and theinvention consists 1n the peculiar construction, arrangement, and combination of parts, hereinafter 40 f, that fits over avibrating lever, G, formed with a cam-surface, G which the walls of said notch engage, and having oneend pivoted to the door H, and its other end forked and embraced by a guide, I, secured to the back plate of the stove, the parts being fitted together in such a manner that when the door is.opened the lever G, beingpivoted thereto, moves with damper-rod farther out of the stove, soithat when the door is opened the damper is opened also, so as tocreate a direct draft into. the chimney, whereby the gas is prevented from coming into the roomthrough the open door. When the door is closed, the lever, by reason of the engagement of its cam-surface with the notch of the damper'rod, again closes the damper, so that the smoke and the products of combustion are compelled to traverse the fines o 0' before passing intothe chimney. It is obvious that the damper can be operated by hand by so raising the rod that the edges of the notch f in the rod will clear the lever G. By makingthe upper portion of the fluestrip and damper curved, as shown, I amenabled to produce a stove having direct draft and up'and-down fines, which will allow of a hole through which a kettle may be inserted .deep in said flues without diminishing to any serious extentthe passage to the chimney of the products-of combustion.

Thedamper-rod F is of peculiar shape, to

admit of its being connected to the damper above the pivot on which the damper turns, in order that the latter may be readily operated by the movement of the'door. To accomplish this it is necessary that a stud, 6, shall be formed on the side of the damper opposite to that on which the damper-rod is situated. The damper-rod must therefore pass through an opening or slot, e, in'the damper E, which is necessarily long, owing to the swinging mot-ion of said damper, and as this the chimney, even when the damper is closed, it is necessary to stop this up, which is done by providing the damper rod with a project ing lug, f, which is of such shape as to close up the slot e when the damper is closed. The

that communicates with the smoke-flue C,

which is covered by the damper K when the latter is closed. As this dust-flue passes through the air-flue, there is necessarily a casopening would allow of a direct passage to $35 ing or boxing, L, between the plates forming the back and front walls of the air-flue. By opening the damper the dust in the ash-pit caused by shaking the grates will be drawn up into the smoke-fines, and thus dust in the room be prevented. The opening of this damper can also be used to check the draft, as apart of the air that enters through the ashplt doors will pass up into the smoke-flue, instead of passing through the fire.

I make no claim to the peculiar mechanism for operating the damper by a connection with the door, as that will form the subject-matter of a separate application.

Having thus described what I consider the preferable form of my improvement, but with out limiting myselfto the construction shown, what I claim is 1. The combination, in astove and with the stove-pipe opening, the casing, and the firepot thereof, of a vertical air-flue, a divided smoke-flue, substantially parallel therewith, both air and smoke fines being between said fire-pot and casing, a direct passage for the products of combustion to the plate having an opening for the stove-pipe, a strip dividing the smoke-flue, and a damper at the upper end of said strip to cut oh the products of combustion from the direct passage, substantially as described.

2. The combination, in a stove having an opening for the smokepipe, a casing, and a fire-pot, of a vertical air-flue, a divided smokeflue, substantially parallel therewith, and both air and smoke fines being between said firepot and easing, a direct passage .for the products of combustion to the opening for the stove-pipe, a strip dividing the smoke-flue, and a curved damper at the upper end of said strip to cut off the products of combustion from the direct passage, substantially as described.

3. The combination, in a stove and withthe fire-pot and easing thereof, of a divided smokeflue, a damper at the upper end thereof, an air-flue ofsubstantially the same width as the stove between the firepot and smoke-flue, and opening through the top plates of the stove, substantially as described.

4. The combination, in a stove and with the casing, the fire-pot, the ash-pit beneath the fire-pot, the air-flue behind the same, and the smoke-flue behind the air-flue, of the dust-flue passing through the air-flue and connecting the ash-pit and the space around the fire-pot with the smoke-flue, substantially as described.

5. The combination, in a stove and with the fire-pot, casing, and smoke-flue thereof, of a vertical air-flue running from the top to the bottom of the stove between the fire-pot'and smoke-flue, and having an opening through it, mostly on one side of the stove, to allow of the passage of the products of combustion from the fire pot to the smoke-flue, substantiallyas described.

6. The combination, in a stove having an ash-pit and air and smoke dues, of two plates forming the walls of the air-flue, and a box held between said plates and forming a dust and check flue, substantially as described.

In testimony whereof I aifix my signature, in presence of two witnesses, this 17th day of February, 1887.

WILLIAM J. KEEP.
