Application February 25, 1935, Serial No. 7,936 1 Claim. (01. 110-14) . This invention relates particularly to an in upwardly away from the rear end of the bins 3 cinerator for the disposal of refuse, garbage and whereby refuse discharged from the bins 3 onto the like. . the conveyor is carried upwardly and dumped into An object of the invention is to provide an a collection chamber 1. All material discharged 5 incinerator which will destroy the garbage and into the collection chamber 1 drops of its own refusev through the combustible activity of the ingredients constituting the same, or through the weight therein into the bottom of said chamber, and wherefrom the said refuse enters a feed tube 8 having either a spiral feed screw therein or A further object of the invention is to provide . a plunger for conveying the refuse, etc., into the 10 an incinerator utilizing a rotary retort through entrant end of the rotary retort 9. The type of 10 which the garbage and rubbish to be burned feeding means contained within the tube 3 may passes in a continuously moving stream, and in be of any desirable character, capable of auto use of additional fuel. moving through said retort is destroyed by burn ing, whereby at the termination of the process, 1;,- the resulting product or refuse is of a sanitary nature which may be disposed of without injury to the public‘health, comfort and convenience. Other objects of the invention are to provide an incinerator that will be superior in point of sim 00 plicity, inexpensiveness of construction, positive “‘ ness of operation, and facility and convenience in use and general efficiency. In this speci?cation and the annexed drawings, the invention is illustrated in the form considered . to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms; and it is also to be understood that in and by the claim fol lowing the description, it is desired to cover the 0: invention in whatsoever form it may be em bodied. In the accompanying drawings: Fig. 1 represents a side elevation of an in cinerating plant constructed in accordance with CD 2.1 my invention. Fig. 2 is a plan View of Fig. 1. Fig. 3 is an end elevation of Fig. 2. Fig. 4 is a section taken through Fig. 1 on the ~10 line 4-4. Fig. 5 is a section taken through Fig. 2 on the line 5—5. In detail the construction illustrated in the drawings comprises an elevated ramp I, running from the ground level to an elevated dumping 5 platform 2, whereby trucks loaded with garbage, refuse and the like, may be driven onto the plat form and the contents of the said truck dumped into a series of collection bins 3 which lie directly below’ the platform 2, each of said bins having 50 inclined and downwardly converging bottom walls which terminate in a discharge chute 4 at the bottom thereof. The discharge end of the bins 3 overlie the upper run of an endless belt 5, a por tion of which runs in a pit 8 beneath the bins 3. 55 The remaining portion of the belt 5 is inclined matically feeding the refuse to be disposed of, into the retort 9. The retort 9 is cylindrical in shape and the 15 outside thereof is provided with rings lB-—I 0 which are supported in bearings I |—H to permit rela tively free rotation of the said retort. A gear I2 is provided around the retort and in meshing engagement with a driving pinion IS on a motor 20 14, said last mentioned unit forming the 'pro pulsion means of the retort. The entrant end of the retort 9 is at a slightly higher elevation than that of the discharge end thereof, and said en trant end of the retort is rotatably journaled on 25 one side of a casing l5, and the said casing and retort at the point of connection are open to communication with each other. The casing l5 may be termed an explosion chamber as will later appear from the description of the invention. The 30 discharge end of the retort 9 abuts in rotatable relationship against one side of a combustion chamber 18, and with which the interior of said retort communicates. The refuse that is dis charged into the entrant end of the retort 9, 35 due to the slope of the said retort and the rota tion thereof, gradually works its way through the length of said retort. As the refuse is pass ing through the retort it is subjected to heat developed by a furnace l8 and thence through a 40 pipe or conduit it into the combustion chamber 16. The refuse itself contains sufficient combus tibles that will ignite with the application of heat thereto, and if necessary, either a gas or oil burner 20 located in the heating box IE may be used to 45 develop flames to generate additional heat to that coming from the boilers ll. A temperature of from 1200° to 4000" F. may be created in the re tort and such a temperature range is suf?cient to completely destroy all of the garbage and rubbish moving through said retort. The com bustible nature of the refuse itself supplies a goodly portion of the ?re necessary to destroy the rubbish, and. the rotary movement of the 55 "2, 107,507 2 retort insures that all of the said ‘refuse will be completely burned= The smoke and products of combustion given off by the burning refuse, flows in a natural path toward the casing l5, and any gases given off dur ing the burning of the refuse which may be of a combustible nature and which may explode, thus creating a pressure within the retort in excess of a capacity which may be accommodated by the retort, is allowed. to escape through expansion door 22 provided on the chamber l5. Such ex pansion would be momentary and as soon as the pressure would be relieved from the retort, the doors would automatically close. However, in order to pull the smoke, names and the gases of combustion through the retort, I have provided a pipe 23 in communication. with the chamber I5, which pipe, at its other end, connects with a wash er 24 for washing the solids and toxic gases out of 20 the smoke, ?ames and products of combustion. A pipe 25 leads from the washer 24 to a suction fan 26, and from the suction fan a conduit 27 com municates with, the furnace l8. The suction fan 26 sucks or pulls the gases, etc., through the re ' tort and washer, and discharges any heated gases which may remain back into the furnace 58, at which point a portion of the gases is directed into an upper compartment 28 of the furnace l8, and the rest into a lowerrcompartment 29, where the gases are burned and completely destroyed. The heat generated thereby is utilized for preheating gases contained in the compartment 28 where from they are reconveyed to the combustion so chamber IS. The combustion which takes place in the compartment 29, being of-a high tempera 35 ture, is forced through the boilers H and isthere by utilized for generating steam. The gases are drawn through the boilers and out into the atmos phere by means of a fan 33. The entire system of 40 furnace, combustion chamber, retort, explosion chamber and washer comprises 'a closed circuia tory system and the refuse passing through said, retort is burned or destroyed under a forced draft. In order to eliminate any obnoxious fumes es caping to the atmosphere from the collection 45 of without injury 'to the ‘public health, as ash re mover 35 being provided beneath the combustion chamber l6. With my system of incineration, the garbage and refuse is completely disposed of without any part of portion of the products of combustion giv en off during the incineration escaping into the air in the form of soot or smoke as is commonly the practice. In my apparatus the continuous re circulation of a certain amount of the used gases 10 of combustion creates an economy in the opera tion of the entire plant, and materially reduces the amount of fuel necessary to effect efficient incin eration. Furthermore, the operation of my in cinerator is odorless in that the obnoxious gases given off during the incineration are captured and put through a washer, after which the remainder of said gases are returned to the furnace and re— circulated. ' , ' In order to care for the intense heat developed in my retort, I have lined the same with ?reproofe or other desirable refractory materials, it being necessary because of the forced draft system and the intensity of the heat developed, to construct the apparatus of material which will not break down under the temperatures used. . Having thus described this invention, what I claim and desire to secure by Letters Patent is: In an apparatus for destructively disposing of garbage; a combustion chamber; an inclined ro tary retort for advancing the refuse to be burned toward said combustion chamber; means in c0m~ munication with the end of said retort opposite said combustion chamber for feeding ,thereinto materials to be burned; an explosion chamber in . communication with said last mentioned end of said retort; a furnace; a passageway connecting said furnace with the combustion chamber; a con- » duit connecting the said furnace with said ex plosion chamber; a blower for maintaining cir culation through the conduit, passage way, com bustion chamber, retort and explosion chamber, said blower creating a forced draft circulation through the system; means for moving the refuse through the retort in moisture extracting relation 45 chamber 1, I have provided a pipe 33 which, at one ' with the ‘not gaseous products in opposite rela 50" end, communicates with the collection chamber ‘I, and at its other end with the pipe 23. The draft created'in the pipe 23 by the fan 26 will draw all obnoxious gases into the pipe 23 and further into the furnace l8. 7 By the time the refuse which enters the retort is discharged out of the discharge end of the same, into the combustion chamber l6,,it falls on the ' floor of said'chamber in the form of an ash or similar innocuous product which may be disposed 40 tion to the direction of movement of the products of combustion therethrough; means for contin ueusiy burning in and venting to the atmosphere through the furnace a selected portion of the gas given off in the reduction of the refuse; and means for discharging from the‘combustion chamber the final products resulting from the termination of the incineration process. 1 MAURICE L.
