GA'RBAG E-CREMATO RY.

SPECIFICATION forming part of Letters Patent No. 592,948, dated November 2, 1897.

Application filed November 25, 1896. gerial No. 613,389. (No model) To all whom it may concern:

Be it known that I, CLINTON B. BoDINE, a citizen of the United States, residing at Camden, in the county of Camden and State of New Jersey, have invented a certain new and useful Improvement in Garbage-Crematories, of which the following is a specification.

My invention relates to a new and useful improvement in garbage-crematories, a de-. tailed description of which,in connection with the accompanying drawings, forms a part of this specification, as hereinafter described.

The object of my invention is to provide a simple, durable, and cheap furnace which will effectually consume garbage and other offensive matter and the offensive and nox ious gases or odors arising from the same at a small expense and little fuel.

Many furnaces which have been designed for the cremation of garbage and other oftensive matters allow the gases to escape too soon into the flue and escape into the air before they are deodorized.

In my improved furnace I provide a retort or chamber for the reception of the garbage or other offensive matter to be consumed. Out of the apex or top ofthe retort or cham; ber leads a gas-pipe which discharges into the combustion-chamber against the sides of the retort. Said pipe is formed in compound curves vertically disposed, and into this pipe the gases escape and radiate in their transit to the fire-chamber, over which they are drawn to reach the flue, and passing over the fire are deodorized, and thus no fumes escape into the air, and into this pipe and elbows is let by a tube a supply of pure air to make a perfect combustion in the fire-chamber of all gases which will arise in the retort or chamher during the time of drying. By the arrangement of the curves of the gas-pipe the infiowing gases offer a greater resistance to tendencies to a back pressure caused by the fluctuation of the pressure in the combustionchamber and are less disturbed by such fluctuations,whereby the gases are caused to How in a steady stream to the combustion-chamber, where they are consumed.

I provide a fire-chamber beneath the retort or chamber, so that all the surface of the section is in contact with the fire, and thus more quickly dry out the garbage or other oftensive matter to be consumed. From the firechamber the gases are passed into the flue by a collar connected to the body and a smoke or gas pipe, which is also connected to the upper section of the retort or chamber, but between which-'. e., the smoke-fiue and retort or chamber is placed a tight slide-damper to prevent the escape of odors into the flue un.

til they have passed through the fire-chamber over the fire.

When the matter in the retort is dried, this damper can be opened and the matter remainin g in retort or chamber burned to ashes, or they can be taken out through the cleanout door, which is placed in the bottom section of the retort or chamber and put upon the fire and thus burned.

I provide a wroughtmetal body with a false or inside metal shield. This body is lined with fire-brick to protect undue action thereon by the fire. At the bottom this body is held in place by a cast-metal bed-plate and at the top by a cast-metal flange or ring, which also gives a bearing for the retort or cham- -ber. I provide a dropgrate with bars, so

that it. can be cleaned easily or the fire easily drawn.

I provide cast-metal doors for the feed, and to remove ashes from the fire-chamber and grate, I provide for the retort or chamber charging or clean -out doors, with a bevelflanged edge inside and out to prevent the odors escaping and with lever wedge-shaped catches.

In the accompanying drawings, Figure 1 is a side elevation of a crematory made in accordance with myimprovement; and Fig. 2, a section thereof, illustrating its interior construction.

A is the casing of the cremator, having a conical top B secured thereto in any convenient manner, and within this casing is supported the retort 0, preferably formed of cast metal and having leading therefrom an opening 1), which is closed by a suitable cap or door E, for the purpose of gaining access to the retort to remove its contents. The top of the casing is also provided with a door F, so fitted thereto by the tapering of its flanged sides as to make it air and steam tight when fitted in place, and this door may be securely sealed by the cam-lever G, which is pivoted to the door, and the nose thereof adapted to pass under the hooked lug II. From the apex of the conical top a line or pipe I leads, and a continuation of this pipe forms the conduit J, made up of a series of compound curves Vertically disposed, and this conduit finally terminates within the casing at K, but has no connection with the retort.

Beneath. the retort is an ordinary furnace having a suitable grate L, which may be arranged to be operated for cleaning purposes and in any suitable manner, and a feed-door M is provided for this furnace in order that the fire may be made and fed, and N represents the ash-pit, which is provided with a door 0.

The furnace is provided with a smoke-pipe P, which leads to the ordinary flue or chimney which provides for the draft in the firebox, and a fine Q is also connected with the retort bypassing through the conical top, and may have therein a suitable damper for opening or closing the passage therethrough.

In operation a fire is started in the furnace so as to bring the retort to the proper temperature, after which the garbage to be cremated is introduced to the retort through the door F, and when this dooris closed and sealed the gases arising from the material in the retort will pass through the pipe I, conduit J, and finally reach the furnace at the point K, from whence they will come in contact with the sides of the retort, which are then highly heated, and commingle with the heated products within the furnace, where combustion of the whole will take place, after which the products of combustion will pass off through which is in proper communication with the atmosphere and has therein a damper S for the regular amount of air which may flow therethrough.

In practice it has been found that when the proper amount of air is mixed with the gases arising from the contents of the retort said gases will be almost completely burned upon entering the furnace, and by reason of the arrangement of the compound curves the gases are caused to flow in such a steady stream to the fire-chamber, as before described, that they are readily consumed. After the contents of the retort have been thoroughly dried and all of the objectionable gases driven there-.

from it may be burned within the retort by opening the damper in the flue Q, thus admitting su flicient air to bring about combustion, or, if desired, the contents of the retort after having been dried may be removed therefrom through the door E and placed within the furnace and there burned.

Having thus fully described my invention, what I claim as new and useful is In a refuse-burner provided with a combustion-chamber, a retort suspended within the combustion-chamber, a conical top for the retort, a gas-pipe leading from the conical top and discharging into the combustion-chamher against the sides of the retort, said pipe being formed with compound curves vertically disposed, and a pipe, having a damper for supplying cool air to the gas-pipe to condense the gases therein.

In testimony whereof I have hereunto atfixed my signature in the presence of two subscribing witnesses.

CLIN"ON l BODINE.
