SPECIFICATION forming part of Letters Patent No. 755,277, dated March 22,1904. 7

Application filed September 24.51903} Serial No. 174,459. (No model.)

To all whom it may concern..-

Be it known that I, P TER J. CoPPENs,a citizen of the United .States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Heating-Stoves; and I do hereby declare the following to be a full, clear, and'exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in heating-stoves; and its object is to provide the same with certain features, and more particularly to that class of stoves having .detachable internal parts and adapted. to operate with or without the same to readily remove and insert the detachable parts, whereby the stove is adapted to burn a great variety of fuel and to burn soft coal and like materials without smoke or waste, and to provide the device with certain new and useful features hereinafter more fully described, and particularly pointed out in the claims.

My invention consists, essentially, in certain modifications of fire pot construction, together with internal attachments of peculiar construction, and adapted to be readily removed or placed in position within the stove, as will hereinafter more fully appear by reference to the accompanying drawings, in which- Figure l is a vertical section of a stove embodying my invention, taken on the line 1 l of Fig. 2 and with the base of the stove omitted; Fig. 2, a horizontal section of the same on the line 2 2 of Fig. 1; Fig. 3, a plan view of the same with the outer cover J removed, and Fig. 4 a horizontal section of the fire-pot on the line L 4 of Fig. 1.

Like letters refer to like parts in all of the figures.

A represents the fire-pot, having the usual truncated conical shape and provided with an air-chamber B in the upper part thereof and inlet-openings B to permit air to escape from said air-chamber over the top of the fire.

C is a suitable coldair inlet to said airchamber, and extending downward on the outside of the fire-pot are any convenient number of air-passages, (preferably three, as shown,) which passages connect the base with the chamber B and supply the said chamber 1 with hot air when the inlet C is closed. The 1 openings B extend only through the front part 1 of the fire-pot, and the'two front air-passages .D have slots or openings E opening into the fire-pot and extending upward into the chamber B, whereby the air is supplied to the front part of the fire-pot from both the chamber B and the passages D. The rear passage D has small openings E near the bottom only and is otherwise closed off from the fire-pot. The air-supply is thus limited to the front portion of the fire-pot and to the lower rear part thereof, the upper rear portion of the fire-pot being without air-supply.

F represents the body of the stove, preferably of the usual cylindrical form and having the usual front door F and atop having an opening closed by the outer cover J The device so far described thus constitutes a complete wood-burning stove having a firepot modified and adapted to cooperate with the attachments Gr, H, and I, hereinafter described, which when inserted adapt the stove to operate as a coalburner having certain novel features of construction and operation whereby the fuel is burned at the front part only and the hot gases therefrom pass all round the magazine and heat the entire body F.,

Above the upper rear portion of the fire:pot

and with its lower rim engaging, the top of the rear portion of the fire-pot and open at the front side for the escape of gases and flames of combustion is a detachable coking-chamber G, having a thickened front wall G extending across from side to side of the upper part of the fire-pot, thus leaving a crescentshaped opening between the chamber G and the front of the stove. This chamber engages the fire+pot throughout about one-half of" the circumference thereof, whereby it issecurely supported without fastenings or other support. Above this coking-chamber is a magazine H, extending to near the top of the stove and terminating in a funnel-shaped portion I, having a flange at the top suitably connected to the top of the stove. This magazine is preferably truncated conical in form, having its small end upward to prevent clogging of the fuel therein, and the funnel I is flanged to fit the opening in the top. The parts G, H, and I thus constructed and arranged will be securely held in place without bolts, rivets, 01' other fastenings and are readily removed or replaced without need of tools of any kind. Within the upper portion 1 is a lid or hinged cover J, to be opened when fuel is to be supplied to the magazine and located somewhat below the top of the funnel I. Covering the opening of the funnel is an outer cover J. These two covers J and J are thus spaced apart, and a chamber is thus formed between them from which is an opening K for the escape into the stove of any gases that may accumulate in said chamber. The part I is readily removed by lifting the same upward, and the parts H and G can then be taken out through the front opening of the door F. These attachments thus are removable through the usual openings without tools and without taking apart of any portion of the stove and when in use are securely supported in place by the fire-pot and top of the stove. When the partsG, H, and I are removed, the remaining stove is then well adapted for burning wood or other like fuel. The parts G, H, and I can also be readily and quickly placed within the stove through the usual top and front openings, and when placed therein they provide the same with a magazine and cokingchamber of peculiar construction and adapted to cooperate with the fire-pot, whereby the stove is adapted to burn either hard coal, soft coal, or slack, and the soft coal or slack will be readily burned without producing smoke, and the combustion will be very complete and economical, the operation being as follows: The fuel is heated in the magazine H and coking-chamber G and also in the rear upper portion of the fire-pot, and by this heating the volatile portions are driven off and escaping forward beneath the front portion G of the coking-chamber G are there supplied with suflicient hot air escaping through the openings E and B to produce a clear blue flame and complete combustion. By the time the fuel has settled down and passed into the front portion of the fire-pot, where it becomes incandescent and finally consumed, the said fuel has become so thoroughly coked that it will then give off no unconsumed carbon or smoke.

The device is also obviously well adapted for burning hard coal, the consumption of the gases being complete and without any wasteful escape ofpartially-consumed gas. In the event that the stove is used for wood or other like fuel the parts G, H, and I are easily and quickly removed for that purpose and again replaced for burning hard or soft coal. I thus secure a practical and eflicient stove for a great variety of fuels.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In combination with a stove having a firepot, a body above the fire-pot, and a top to the body having an opening and a cover; a coking-chamber, a magazine and a funnel extending continuously from the opening in said top to the fire-pot, and detachably supported in place solely by the fire-pot and top.
