DOMESTIC GARBAG E-BURNER.

SPECIFICATION forming part of Letters Patent No. 670,806, dated March 26, '1 901.

Application filed June 7.1900. Serial No.19A77 (No model.)

To all whom it may concern.-

Be it known that I, ELLEN S. NowLAN, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Domestic Garbage-Burners, of

which the following is a specification and which are illustrated in the accompanying drawings, forming a part thereof.

The objects of the invention are to provide a cheap, convenient, and efficient furnace for the consumption of garbage which may be placed over the plate-hole of a stove and discharge the products of combustion into the smoke-flue of the stove and which may be easily mounted upon astove or removed therefrom.

The invention consists in a vertically-cylindrical combustion-chamber having a grate or perforated bottom, an inclosing cylinder or jacket forming an air-space around the combustion-chamber, a smoke-flue leading from the outer jacket, and various further details of construction, all as illustrated in the accompanying drawings, in Which Figure 1 is a vertical section of the device mounted upon a gas-stove, which is shown in detail side elevation, some of the parts being broken away; and Fig. 2 is a plan section of the device on the line 2 2 of Fig. l.

The garbage-bnrner may be used upon any kind of a stove. I show in the drawings a portion of an ordinary gas-stove 10, having a burner 11 and a flue-pipe 12, which leads from its oven, as is usual in gas-stoves, and is adapted to connect with any smoke-flue.

The outer shell or case 13 of the garbageburner is made of sheet metal and is cylindrical in form and is adapted to rest upon the top of the stove 10. The furnace or firebox portion of the garbage-burner is shown at 14 and is also cylindrical in form and made of sheet metal and is of somewhat less diameter than the cylinder 13, so that it may be located within the same and walls spaced apart.

The inner cylinder may be loosely and removably supported by means of lugs 15, riveted to its outer surface and preferably near its upper end, these lugs being adapted to rest upon an annular flange 16, projecting inwardly from the walls of the cylinder 13.

This flange is shown as being formed by folding the upperend of The cylinder 13 inwardly.

The cylinder 14 is somewhat shorter than the cylinder 13, so that its lower end does not reach entirely to the top of the stove 10, thereby allowing for the circulation of air upwardly through the space between the two cylinders when the device is used in connection with a gas-stove.

The bottom 17 of the cylinder 14 is shown as being of sheet metal freely perforated, as shown at 18, though any other form of open bottom which will support the mass of gar bage 19 may be employed.

A flue-pipe 20 projects outwardly from the I wall of the cylinder 13 near its top, and an aperture 21 is formed in the wall of the cylinder 14, so that it may register with this flue. The pipe 20 is a short section and is adapted to be connected with the nipple of a T 22, incorporated into the flue-pipe 12 of the stove 10.

A cover 23, having a suitable handle, is adapted to fit into the upper end of the cylinder 13, so as to make a reasonably close joint.

In use the garbage 19 is deposited within the inner cylinder 14:, the latter having been placed within the outer cylinder and the latter having been mounted upon the stove and its pipe 20 having been connected with the nipple 22. The cover 23 is adjusted to its place, and the flames from the burner of the stove are thereby caused to pass upwardly through the perforated bottom 17, igniting the combustible portions of the garbage and quickly developing therein a sufiicient fire to entirely consume the Whole mass, an adequate air-supply passing upwardly with the flame to support combustion. The smoke from the burning garbage passes off through the pipe 20, and the outer cylinder serves as a shield to inclose the highly-heated walls of the inner cylinder. So much of the vapors as pass up through the stove and do not find ready outlet through the inner cylinder pass off through the annular space surrounding it. As soon as the garbage becomes well ignited the flame, if a gas-stove is being used, may 100 be turned down or entirely extinguished, as the garbage ordinarily contains sufficient combustible material to insure its own red uction.

The annular space between the two cylinders is so small that it is not adequate to carry oi? the burning vapors issuing from the stove, and consequently the major part of the draft is directly through the inner cylinder. The outer casing is of less value when'the device is used in connection with a coal-burning stove than when employed with a gasstove, for the reason that in the former case the only circulation through the intervening space between the two cylinders is necessarily smoke or gases evolved from the flame. The circulation of the latter, however, is so slight that the outer cylinder is much less highly heated than the inner cylinder.

I claim as my invention 1. A garbage-burner comprising a pair of concentric cylinders open at their lower ends to rest over a hole in the stove-top, and having a discharge-flue, whereby the inner cylinder may form the flue from the stove, and a supporting-screen for garbage located across the last-named cylinder and located above the lower end thereof.

2. In a garbage-burner, in combination, an open-ended cylinder 13 adapted to rest upon a stove-top and inclose a stove-hole, and having an instanding flange 16, a smaller and shorter cylinder 14: having lugs 15 for resting upon the flange, and having a flue-aperture near its upper end, a perforated screen across the cylinder 14 above its bottom, such cylinder being adapted to convey the products of combustion from the stove, a removable cover 23 for the upper end of the cylinder 13, and a flue-pipe 20 leading from such cylinder, substantially as described.
