l4lc1aims. (orizz-2i Objectsof the present invention are .to provide an incinerator for community use and which comprises a double unit construction having boilers attached, if desired; to provide a simple, eine cient andcomparatively inexpensive community incineratorrwhich shall be economical and eficient in operation to provide for 'drying and burning the rawgarbage on both sides Vor faces at the same time thereby tory decomposition. VOther `objects of thev invention will appear .from the following 'description at the end of which the invention will be claimed.

Generally stated, the invention comprises the improvements to be presently described and flnally claimed.

In the following description reference will be made to the accompanying drawings and forming part hereof and in which,

Figure 1 is a longitudinal central section through one of the units of the incinerator showing means for drying and' burning raw garbage on both sides or faces at the same time and taken on the line I-I of Figure 2.

Figure 2 is a horizontal sectional View showing both units of the incinerator and alsoI the nues for preheating air.

Figure 3 is an end elevational view of one of the units showing the other unit in transverse section.

Figure 4 is a side elevation of my device.

Figure 5 is an end view of my device with parts in vertical cross-section. Y

Figure 6 is a top plan view of my device with parts in horizontal cross-section.

Referring to the drawings, a description of one of the units will suffice since they are duplicates of each other and for this purpose the unit shown at the bottom of Figure 2 and in Figure 1 will be referred to. I is a partition wall which subdivides the furnace structure into two units. Each unit is subdivided into three compartments of which 2 is for the combustion of rubbish `and the second 3 is for drying and consuming garbage and of which the third 4 is provided with a steam boiler and is for the reception of hot gaseous products from the other two compartments. 5 is a baiile wall arch and 6 is a bridge wall and they are arranged between the first and second compartments. 'I is a checkerbrick baille wall between the second and third compartments. 8 is a grate in the iirst compartment and it is arranged below the bridge wall 6. There are two grates S and Ill in the second compartment and the upper one 9 is inclined and is water cooled.

effecting I its satisfac-v The watercooling is best accomplished by the means'shown in Figures 4, 5 and 6.r Itmay consist of a supply pipe 5D leading from a reservoir .or other source of supply to an inlet` header or manifold 5I,'fro1n which lead olf a number of branch pipes 52 controlled by the valves indicated at` 53. Pipes -52 llead to the bars of grates 9, Whencethe waterisv conducted through pipes 6|! controlled byvalves 54 toy the outlet manifolds 'or headers 55. From the outlet manifolds or 10 headers 55 water is conducted through pipes '56 lto pumps 5l', ,whence it is returned to the reservoir .or other source o f supply through pipes 58. This .upper grate Sis substantially aligned With the lower portion of the baifle wall l and is in the 15 path of hot combustion products which dry and burn garbage on both faces or sides. There are air ducts Il and I2 arranged and heated in the partition wall I and in the side walls I3. These ducts discharge above the grate 8 in the rst 20 compartment and they also discharge above the bridge wall and above and below thexinclined grate 9 in the second compartment. I4 and I5 are inlet chutes through the tops of the rst and second compartments. I6 is a stack flue for 25 the third compartment. Il are clean-out doors for the various compartments. When the incineratorv is in operation rubbish introduced through the chute I4 is burned in compartment 2 heating up the walls of the compartment which 30 impart their heat to the air entering by the ducts Il and I2'and this preheated air stimulates combustion of the rubbish and also of the hot products of combustion evolved therefrom. The hot products of combustion from the chamber 2 pass over 35 the bridge wall 6 and under the baille wall 2 and pass both above and below the water cooled grate 9. Garbage is introduced through the chute I5 and while on the grate 9 is burned and dried on both faces not only by the hot products of com- 40 bustion in the compartment 2 but also by the combustion with secondary air of any combustible gases that have not been ignited. Garbage along with any rubbish that may enter with it is further burned upon the grate Iii. The hot prod- 45 ucts of combustion leaving the second compartment 3 pass through the openings in the baille wall I and in the compartment 4 impart their heat to the steaming boiler I8 and escape by Way of the stack I6. I9 is a steam line provided with 50 appropriate valves and adapted for use in leading off steam from the boiler I8.

It will be obvious to those skilled in the art to which the invention relates that modifications may be made in details of construction and ar- 55 rangement and matters of mere form without departing from the spirit of the invention which is not limited to such matters or otherwise than the prior art and the appended claims may require.

I claim:

1. A double unit community incinerator comprising in combination a furnace structure having a partition wall subdividing its interior into two units, each unit subdivided into three communicating compartments, a bridge wall and a baie wall arch between the rst and second compartments, a checker-brick baille wall between the second and third compartments, a grate in the first compartment below the bridge wall, two superposed grates in the second compartment and of which the upper one is inclined and is aligned substantially with the top of the bridge wall and the bottom of the baille wall arch and is in the path of hot combustion products to dry and burn garbage on both faces or sides at the same time, a steam boiler in the third compartment, air ducts arranged in the walls of the structure and discharging into the first and second compartments above and below the inclined grate,Y inlet chutesfor the rst and second compartments, a stack flue for the third compartment, and clean-out doors for the compartments.

2. yIn a community incinerator, the combination of, three communicating compartments, a bridge wall and a baiiie wall arch between the first and second compartments, a `grate in the rst compartment below the bridge wall, two superposed grates in the second compartment and of which the upper one is inclined and is aligned substantially with the top of the bridge wall and the bottom of the baille wall arch and is in the path of hot combustion products to dry and burn garbage on both faces or sides at the same time, means for passing water through said upper one of said grates to cool it, and a water boiler in said third compartment.

3. In a community incinerator, the combination of, two intercommunicating compartments, a bridge wall and a baffle wall arch between said compartments providing a vertical passage between said compartments, a grate in one compartment, and a pair of superposed grates in the other compartment of which one is inclined and water cooled and is aligned substantially with the top of the bridge wall and the bottom of the baille wall arch and is in the path of hot combustion products to dry and burn garbage on both sides or faces at the same time.

'4. In a community incinerator, the combinavtion of, two intercommunicating compartments, a bridge wall and a baffle wall arch arranged between said compartments and providing a vertical passage between said compartments, a grate in one compartment, a pair of superposed grates in the other compartment of which one is inclined and water cooled and is aligned substantially with the4 top of the bridge wall and the bottom of the baie wall arch and is in the path of hot gases to dry and burn garbage on both faces or sides at the same time, and means for introducing secondary preheated air above and below said inclined grate.

Y CHARLES I. NIELSEN.
