GAS-STOVE.

SPECIFICATION forming part of Letters Patent No. 473,285, dated April 19, 1892.

Application filed August 19, 1891. Serial No. 403,082- (No model.)

My invention relates to improvements in gas-stoves; and the object of my invention is to produce a simple and inexpensive stove which by the consumption of aoomparatively small quantity of gas will throw out a great deal of heat, which affords a convenient means of supplying pure air to a room, which carries off all the noxious products ofcombust-ion, and which may be used to heat water so that it may be conveniently carried to a bathroom or wherever desired.

To this end my invention consists in certain features of construction and combinations of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a vertical section of the stove embodying myinvention. Fig. 2 is a sectional plan on the line 2 2 in Fig. 1, and Fig. 3is-a sectional plan on the line 3 3 in Fig. 1.

The stove is provided with an outer shell 10, which incloses the combustion-chamber, and which is provided with a suitable base 11, which base rests, preferably, on legs in the usual way. The shell 10 is provided with an inlet-pipe 12, which may be supplied from out of doors and which gives the necessary oxygen to promote combustion,and this pipe is preferably arranged near the bottom of the stove. The shell 10 has also a vent-pipe 12, which is arranged near the top, and which may be arranged to deliver the smoke out-ofdoors, and the inlet and outlet pipes are protected by check-plates 12 to guard against sudden gusts of wind.

Within the shell 10 is a cylinder 13, forming an inner air-chamber; but the walls of this chamber may be made in any other shape as well as cylindrical. This cylinder is closed at the bottom, and is provided with an inletpipe 14, which projects upward through the bottom of the stove and enters the bottom of the cylinder, and this pipe is adapted to extend to a point out of doors, so as to supply perfectly-pure air to the cylinder. Opening from the top of the cylinder and through the top of the stove is a pipe 15, which permits the heated pure air to escape into the room.

Beneath the cylinder 13 is a gas-burner 17, whichmay be of anyapproved construction and which is supplied by a gas-pipe 18. A circulation-pipe 19, which is filled with water and which may extend to any desirable point, enters the stove near the top and is formed into coils 20 and 21, one coil 20 being arranged Within the cylinder 13 and the other coil 21 around the outer portion of the cylinder, and it will be seen that the circulationpipe will thus have a large heating-surface, so that the water in the pipe may be quickly heated. The stove is provided near the bottom with a suitable door 22, which enables the gas-burner to be easily reached. When the gas is lighted, it will burn freely, owing to the constant supply of fresh air which enters through the pipe I 12, and the noxious products of combustion will pass off through the pipe 12. The ascending'heat heats the cylinder 13, thus creating a circulation of air, the heated. air passing out through the pipe 15 and the fresh air entering through the pipe 14. The heat from the burner will also heat the coils of the circulation-pipe, so that there will be a good supply of hot water in the pipe, causing the wa ter to flow downward through the coil 20 and upward through the coil 21 and out through the upper one of the two pipe ends 19, (shown in Fig. 1,) and the stove will heat by direct radiation and also by ejecting the hot air into the room, so that with a small supply of gas a comparatively large quantity of heat will be produced.

As shown and described, the outer shell and the inner chamber are of a oylindrical shape; but it is obvious that the stove may be given any desired shape and that the walls of the inner chamber may be made to conform to the shape of the outer shell.

Having thus described my invention, what claim as new, and desire to secure by Letters Patent, is-

A gas -stove comprising the two closed drums, one Within the other, and each provided with inlet andol'ftake pipes leading to the outer aiiga burner under the inner drum, and a water-pipe extending through the two drums, coiled downwardly Within the inner drum, extending therethrongh, and coiled upward around the outside of the inner drum,

and then extending out through the outer drum at a higherpoint than where it entered, I0 substantially as set forth.
