DOMESTICREFU;S.E-CREMATORY.

SPECIFICATION formingpart of Letters Patent No. 730,004, dated June 2, 1903. Application filed July 22, 1902. Serial No. 116,486. (No model.)

To rtZZ whom it may concern.

Be it known that I, J OSEPH HENRY GorrER, a subject of the King of Great Britain, and a resident of Winnipeg, in the Province of- Manitoba and'Dominion of'Oanada, have invented a new and Improved Domestic Ref use- .Grematory, of which the following is a full,

vide means adapted to expose a large area of the refuse to the action of an incandescent 'bed of fuel, to allow the refuse to be partially embedded in the fuel-bed incontradistinction to a mere suspension thereover in order to secure better and quicker results, to provide for the free ingress of air to the burning part of the refuse so as to properly support combustion, and to provide means by which a limited vertical play is permitted to the refuse-container in order that it may sink into the bed of fuel as the latter is consumed.

To the accomplishment of these ends my invention consists of a domestic crematory embodying certain novel featu res of construction and arrangement, which will be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both thefigures.

Figure 1 is a vertical sectional elevation through a refuse-crematory applied in operative position to an ordinary cooking-stove, and Fig. 2 is a detached perspective view of the refuse-container.

5 designates an exterior shell or jacket, which is provided with a removable cover 6 at its upper end, said cover being equipped with a suitable handle 7, and the jacket is, furthermore, provided with handles 8, which are secured to the opposite sidesthereof. The jacket or shell is open at its lower end, and it is adapted to be placed on the top of a cooking-stove in a position to inclose one of the lid-holes therein. Within the jacket is arranged arefuse-container 9, which is shown by the drawin s in theform of a wire basket,

the'same fitting loosely within said jacket and preferably. suspended therein by means which permit said container to have a limited independ'entmovement or play. Although I have shown this container as constructed of heavy wire fabric, it will be understood that any appropriate material may be employed in the manufacture of the basket-as, for example, sheet metal or other foraminous metallic substance. 1 The basket or container is open at its upper end in order that refuse may be easilyintroduced therein when the cover 6 is removed from the exterior shell or jacket, and

this basket is preferably cylindrical in form,

although the shape is not material.

The bottom 10 of the basket or container is inclined, as shown more clearly by Fig. 1,. and one side of the basket is considerably shorter than the other side, thus-allowing the long side of the basket to extend well down and into the combustion-chamber or fire-box 11 of an ordinary cooking-stove, which is indicated partly at 12. The basket, having the inclined or sloping bottom, may be loosely suspended within the jacket or shell by any preferred means; but, as shown by the drawings, the suspending means comprise a series of chainsor their equivalents 13, the latter being fastened to the edge of the open-mouth ,portion of the container and tosuitablc hooks or eyes 14., which are firmly attached to the inside of. the jacket or shell at a suitable distance below the removable cover 6 thereof.

15 dcsignates an air inlet or supply tube which is arranged to extend into the basket "or container and is adapted to have communication with the outer surrounding atmos- 'phere,and in the service of the crematory this tube supplies the air to the lower burning part of the refuse in order to properly support combustion. If, desired, the air-inlet tube may be attached to the jacket or shell 5 and arranged to fit loosely in a suitable opening provided in the basket or container; but in view of the fact that the basket is adapted to have a limited vertical play within the jacket I have shown the air-inlet tube as being attached to said basket or con tainer in order-that it may travel or play therewith. The upper end of the inlet tube is disposed adjacent to or arranged to play in an air-feed opening 16, which is provided in one side of the jacket or shell 5, at the lower part thereof. Any suitable means may be adopted for attaching the inlet-tube securely to the basket in order that it may travel therewith, and this tube is adapted at all times to have communication with the surrounding atmosphere through the inlet opening or port 16.

In using my improved device the garbage and other refuse may be introduced into the container or basket before the structure is placed on the cooking-stove, or said structure may be first placed in position and then the v refuse may be introduced into the container, the cover (3 being removed for this purpose. The shell is adapted to rest snugly upon the top of the cooking-stove, and the cover 6 serves to close the shell,'except at the airinlot 16, thus preventing the escape into the room of any fumes or odors which may arise from the refuse during the operation of oremating the same.

The inclined or sloping bottom of the container is of considerable importance, because it provides a larger area of the mass of refuse, which is exposed to the action of the heat, and the bottom furthermore makes the lower part of the basket or container extend Well into the fire-box or combustion-chamber of the stove. In fact, the lower part of the container or basket is adapted to be embedded into the mass of incandescent fuel on the grate, thereby securing a better and quicker efifect in the reduction of the garbage. At the same time the heat and products of combustion are free to circulate through the basket and into the flue of the stove, and the tube 15 supplies the necessary air into the body of the burning refuse, thus promoting the combustion.

As the bed of incandescent fuel sinks or decreases in volume, the basket is adapted to automatically lower itself in order to properly present the refuse to the action of the heat, and this is secured by the employment of flexible suspension-chains which serve to limit the downward movement or displacement of the basket that is suspended from the stationary jacket or shell.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A domestic .refusecrematory having a shell or jacket, a container housed therein, and means for loosely suspending said container and permitting it to be lowered by gravity relative to the shell or jacket within the limit of the suspension means.

2. A domestic refuse-crematory, co1nprising a suitable shell or jacket having an airinlet, a container within said shell or jacket, and an inclined air-tube extending into the container toward the bottom thereof and having communication with the air-inlet of the shell or jacket.

3. A domestic refuse-crematory, consisting of an exterior shell or jacket having an airinlet, a container provided with an inclined or sloping bottom, means for loosely suspending said container within said shell or jacket and permitting the container to have a down- Ward movement within the limit of said suspension means, and an air-inlet tube extending into said container and movable therewith.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
