INCINERATOR.

Specification of Letters Patent.

Patented Jan. 3, 1922.

Application filed September 15, 1919. Serial No. 323,705.

To all whom it may concern! Be it known that I, EDWARD M. Jones, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented a new and useful Incinerator,of which the following is a' specification.

This invention relates to incinerators designed primarily for the reduction of garbage, dead animals, night soil, and general city refuse. One of its objects is to simplify and reduce the cost of construction of apparatus of this character, and also to reduce the cost of operation by utilizing waste heat for preheating air fed to the fire box and to the combustion or reduction chamber. Another object is to utilize the hot gasesgenerated "in the combustion chamber for the purpose of facilitating the drying of the garbage or other refuse supplied to the said chamber whereby it can be quickly reduced .to a condition enabling it to be used as a fuel for carrying on the operation of the incinerator.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of the combination and arrangement of parts hereinafter more fully described and pointed out in the claim, it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention 1s set forth in" the appended claim.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a central vertical transverse section through an incinerating plant constructed in accordance with the present invention.

Figure 2 is an enlarged section on line 2-2, Figure 1.

Figure 3 is a section on line 3-3, Figure 1.

Figure 4 is a section online 4-4, Figure 1.

Referring to the figures by characters of reference, 1 designates a base on which is erected the circular wall 2 of the incinerator, said wall supporting a dome 3 which is preferably coveredwith a heat insulating mate-.

rial 4 over which may bef'extended a cover 5 of sheet metal or the like. jacket, pref- A stoke door 31 erably of sheet metal, is extended around the wall 2, as shown at 6, to form an air space 7 having air inlet perforations 8 close to the top thereof.

A wet pan 9 is constructed within the space inclosed by the wall 2 and extends diametrically across said space, the sides of the pan. being preferably inclined as shown at 10 and having their upper portions flush with side grates l1. Stoke doors 12 are provided in the wall 2 at the sides of the grates 11 so that access can be had readily to the grates and the contents of the wet pan.

Parallel walls 13 are extended outwardly from the walls 2 and are connected by an arch 14:, the jacket 6 and the air spaces 7 being extended along these walls, as shown in Flgures 3 and 4 and the arch being provided with a covering 15 of heat insulating material. An ash pit 16, having an ash door 17, is provided between the lower portions of the walls 13 and a grate 18 extends over this ash pit and up to an outlet 19 which opens through the wall 2 above one end of the wet pan 9. v

An outlet 20 is formed in the wall 2 above the Ether end of the wet pan and opens into a flue 21 extending downwardly to one end of a flue 22 formed under and extending longitudinally of the wet pan. The other end of flue 22 opens laterally into another flue 23 parallel therewith and which extends to the base of a stack 24, there being a clean out door at the back of the ash pit 16 and opening into the flues 22 and 23 at their point of communication, as shown at 25. A dam'peris mounted in, flue 23 close to stack 24: and can be operated in any manner desired. For example this damper, which has been shown at 26, can be connected by a chain or cable 27 to a suitable operating means or to a counter balance 28. Ash pits 29 are located at the sides of the flues 22 and 23 and under the grates 11, there bein ash doors in thewall2 and openings into sai pits. opens into the space above the fuel grate 18, as shown in Figure 2.

Air ports'32 open into the ash pits 29 from the air spaces? and dampers 33 are used for controlling the flow of air through said ports. Additional ports 34 open into the ash pit 16 from said air spaces and are provided with dampers 35.

A charging hole 36 is formed in the center of thedome 3 and is normally closed by a plug 37 which can be raised and lowered by a hoist 38 or any other suitable means.

In using the apparatus an initial charge of fuel is ignited on the grate 18 and the generated heat will flow into the combustion chamber C above the wet pan 9 and thence down through flue 21 to flues 22 and 23 and to the stack 24. This will result in the thorough heating of the chamber and heat conducted through the walls of the apparatus will preheat the air within the spaces 7 and which air will enter the ports 32 and 34 so that practically all of the heat will be utilized. After the chamber C has been heated to a desired temperature, the plug 37 is removed and the garbage or other material .to be incinerated is discharged through the opening 36 onto the wet pan. The heat passing over this deposited material will quickly dry the upper portion thereof and, passing through the fines 22 and 23 to the stack, will drive moisture up from the bottom of the pile and facilitate drying of the entire mass. As the upper portion of the pile is dried, it is drawn laterally onto the grates 11 by a tool inserted through the stoke doors 12. The material here deposited will be met by the hot preheated air entering from port 32 and will be ignited thereby. Thereafter it becomes unnecessary to utilize fuel on the grate 18 because the operation will be maintained by the burning dried material on grates 11.

As more material is required, the plug 37 is removed, the material discharged through opening 36 and the plug replaced. By means of the damper 26 the fiow of hot gases through the fiues 22 and 23 to the stack can be controlled.

As shown in the drawings the entire inc'inerator can be arranged in a housing 39 suitably arranged to facilitate operation of the plant.

What is claimed is The combination with a combustion chamber, grates at the sides thereof, and a wet pan interposed between the grates, of a fuel supporting grate at one end of the wet pan, a stack, a fine communicating with the combustion chamber adjacent the stack and passinglongitudinally under the wet pan toward the fuel grate and thence back to the stack to heat the bottom of the wet pan with the hot products of combustion passing to the stack from the combustion chamber, and doors within the wall of the combustion chamber for facilitating the drawing of dried material from the wet pan and onto the grates at the sides thereof.

In testimony that I claim the foregoing as my own, Ihave hereto affixed my signature in the presence of two witnesses.

EDWARD MOORE JONES.
