Application filed October 26, 1903. Serial No. 178.548.

To all whom it maly concern;

Be it known that we, WILLIAM J. KEEP and HENRY C. MAUL, citizens of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Stoves; and

.we declare the following to be a full, clear,

Figure 1 is a perspective View of a stove embodying our Invention, a part being removed to show the interior .construction Fig. 2 is a plan showing a section on the line 2 2 of Fig. 1. Fig. 3 is a detail section of the upper part of the stove, the section being taken along the broken line 3 3 of Fig. 2. Fig. 4 is a vertical elevation principally in section. Fig. 5 is a section showing the airadmission passa es on the line a a of Fig. 8. Fig. 6 is a detai perspective of a casting in which are air-admission passages. Fig. 7 is a view similar to Fig. 5 on theline b b of Fig. 8. Fig. 8 is a segmental elevation of 'the casting shown in Fig. 6, attached to the coalreservoir. 9 is a cross-section on the line 9 9, F' 4.

A is the epot.

B is the coal-magazine.

C is a passagev for the products of combustion and ases on their way to the flues. The passage C is separated from the ma azine B y an air-space L, open laterally to t e outer air, Fig. 9. The magazine B and plassage C ferm the body of the stove. T e wall bounding the air-space L at its lower end divides the magazine and passage() and forms a bridge-wall.

D indicates branches of a passage connecting the iuc E with the passageY C.

F is a hopper for. receiving the coal when it isbeing supplied to the magazine.-

f is a removable cover for the hopper F.

G is a cover for the magazine B, winch cover rests upon the upper end of said magazine between the same and the lower'end of the hoppergF. There is sufficient distance beform a part of this speci cation.`

`the casting tween the upper end of the ma aizine B and the lower end of the hopper to allow of some vertical movement of the cover G. The cover G is provided with a handle g, ex-l tending to the outside of the stove, and said cover may be withdrawn from off the magazine B by drawing outward on the handle g. The outer end of said handle passes through a slot in the outer casing of the stove with a reasonably close fit. l

H is a fire-door having at its upper part, nea-r its hinged edge, a lug h. vIn the outer end of said lug is Jformed a hole into which the'downturned end of the rod l projects, which rod passes horizontally for a short distance, then slantingly upward through a hole in a stationary lug 12, and its upper end rests against the lower surface of the inner portion of the handle g'. When the fire-door H is opened, the lug h is carried inward in an approximately horizontal plane, carrying with it the lower end of the rod I and presses said rod u ward through the lug 12, because of the s anting direction in which said rod passes through the aperture inthe lug 12.

J is a casting forming a casing which when in place on the side ofthe magazine forms a passage J2, open at the bottom and closed at the top.

Ja is a passage formed between the inner wall of the casting J and the wall surrounding the magazine B, which passage passes approximately vertically downward opening into the magazine B through a slot j. The

casting J is secured tothe wall of the magazine B in the air-space L between said magazine and the assage C. The magazine under is cooled bythe passage of air. The magazine B is formed with an offset j, over which the casting J is fitted. The slot y" is formed vertically through the approximately horizontal upper part of said offset.

K is a lattice-work of ornamental design partially surrounding the body of the stove, leaving a space between said lattice-work and the body of the stove.

of the Stove and the lattice-work K and opening into the room or communicating with a pipe leading to an upper room.' The flue K asses through the hot-air passages, `so as to lie surrounded by the hot flue-gases.

By the above construction when Athe fire- IOO , l K is a hot-air iue communicating at its lower end with the space between thebody 'door H is open the cover is slightly raised, L

leaving a space between it and the upper part of the magazine B, so that the interior of said magazine communicates with the iiue E, and the gases are not liable to be thrown out at the open lire-door. When said door is again closed, the cover G falls back into position upo'n the upper end of the magazine B.

It will be observed that by the construction above described .that a passage J3, directing a current of air into the magazine through a long narrow slot J in an approximately vertical direction, is provided. This bustion immediately as they -pass out from the stove. The lower end of this flue communicates with the space between the hot bod of the stove and the'ornamental latticeworli surrounding the same. Thus a draft is occasioned not onl 'by the hot-air in the Hue itself but also by t e hot air between the lattice-work and the body of the stove. The

lattice-work is heated by radiation from the body of the stove, and the heat absorbed is taken up by contact b the air passing through the apertures in t e lattice-Work and to the flue K.

At the upper end of the flame-Hue in front thereof is a door or section adapted to be swung outward around hinges at its upper edge, as indicated in dotted lines, so as to admit air to said flue and regulate the draft of the Stove.'

What we 'claim is- In a stove, thecombination ca magazine, having itsv upper end communicating with a flue-passage when the cover is lifted, a cover adapted to close the upper end cf said magazine, a fire-door adapted to swing in a horizontal plane and cover an opening in a side wall of the stove in a plane below that of the cover, said doorbeing provided with a lug eccentric to the pivot thereof, and a rod engaging said lug 'and cover, said rod being normally located in an inclined position, for the purpose described.

In testimony whereof we sign this specification' in the presence of two witnesses.
