Many disposal expedients have been used including burying but it has been found, that the most efficient and acceptable methods of disposing of these materials is by incineration. Unfortunately, the organic material is not readily burnable and when it is incinerated, there is frequently generated objectionable obnoxious gases, smoke, and the like and the product is frequently incompletely combusted and therefore leaves an undesirable residue.

OBJECTS OF THE INVENTION One of the principal objects of the present invention is to provide a new and improved incinerator which is economical to construct and operate and which is especially adapted for disposing of organic materials such as pig fetuses and the like.

A further object of the present invention is to provide an inexpensive incinerator having an efficient burner in which the interior of the incinerator is substantially uniformly heated and to a temperature which will effect substantially complete incineration of the organic materials charged within the incinerator.

A still further object of the present invention is to provide efficient, complete and rapid combustion of all the organic products charged to the incinerator and in which the organic product is reduced to a fine ash.

The gaseous effluent is substantially clear and colorless.

Other objects and features of the invention will become apparent from a consideration of the following description which proceeds with reference to the accompanying drawings, wherein a single example embodiment of the invention is chosen to illustrate the invention.

DRAWINGS FIG. 1 is an isometric view of the invention of the incinerator with the stack in fragmentary view;

FIG. 2 is a front elevation view of the incinerator with a portion of the interior of the housing illustrated. The ash door at the right-hand side has progressive opening positions in dotted lines and full lines;

FIG. 3 is an end view looking in the direction of the arrows 3-3 in FIG. 2;

FIG. 4 is a section view taken on line '4-4 of FIG. 2;

FIG. 5 is an isometric view of the rake which is used to remove the ash; and,

FIG. 6 illustrates the ash removal procedure, a portion of the casing being shown broken away to illustrate the interior, and the rake being illustrated in full and dotted line positions to indicate the method of ash removal.

DETAILED DESCRIPTION OF THE INVENTION Referring to FIG. 1 the incinerator designated generally by reference numeral 10 includes a cylindrical casing 12 having end closures l4 and 16 and charge opening 18 disposed at the upper surface 20. The opening 18 is normally covered by a charge door 22 which is hingedly joined at 24 and 26 to the casing 12, there being a lift handle 30 to raise and lower the door.

Casing rests on two spaced pedestals 32 and 34 consisting of legs 38 which are inclined and are secured to the exterior surface of the casing in some suitable manner as by welding 40. The legs 38 are then secured together by means of an angle iron pedestal 50.

Located at end closure 16 (FIGS. 2,4) is an oil fired injector burner 54 where the burner assembly is held in place. As shown in FIGS. 2 and 4, the burner ejector nozzle 60 ejects a flame 62 which extends in a conical line of fire commencing from the nozzle 60 and projecting sufficiently so that it substantially engulfs all of the organic product 68 on base 70.

The idea of course is to generate a substantial uniform temperature from one end to the other of the casing, so that there is an exposure of the entirety of the organic material to the oxidizing effect of flame 62 throughout all portions of the organic material 68.

The organic material is fed to the incinerator through opening 18 by first lifting the door 22 through handle 30 and swinging it backwardly to the dotted line position FIG. 2.

The gaseous oxidation products are vented to atmosphere through a stack 76 having an outlet opening 78.

The stack 76 is located at the end of the casing remote from the burner and the gaseous outflow from the stack is clear and virtually solids-free.

After the burning is completed, the organic material is reduced to a fine inorganic'ash and periodically, the ash is removed by means of a rake 80 consisting of a handle 82 and a semicircular cross section plate 84 which conforms generally to the rounded interior contour of the casing (FIGS. 4,6) whereby ash 86 is removable from the interior of the casing through opening 88 when the ash door 15 is raised-from the full line position (FIG. 2) first to the intermediate dotted line position 90 (FIG. 2) thence to the fully raised, dotted line position 92.

The ash door is supported at space points on hinges 96. The ash door 15 is held in place in a closed position (FIG. 3) by means of a releasable latch mechanism 98.

OPERATION In operation, the charge door 22 is first raised by means of handle 30 and the interior of the casing is charged with organic product 68 intended to be burned. The charge door is then lowered and the burner 54 commences operation, projecting a hot flame 62 which projects conically forwardly from the nozzle outlet 60 completely engulfing the product 68 in flame. The organic product is completely consumed, and the product of combustion exits through the stack 76 as a clear substantially solid-free gaseous outflow. The one residue is in the form of a light inorganic ash which is periodically removed by raising the door 15 on its hinges 96 and using a rake 80 to scrape the ash from the bottom 70 and into piles 86 as indicated in FIG. 6.

The incinerator is quite efficient, and can quickly convert a substantial volume of organic material to a uniform ash product which is substantially entirely free of organic material. The ash is volumetrically, only a small proportion of the original bulky organic material and therefore its discarding presents virtually no problems whatever.

The details of the burner construction are obtainable from Wayne Corporation, Catalogue No. EHA.

It is not necessary to remove ash following each burning operation, the user can continue to dump organic material and repeat the incineration operation and this can continue until sufficient ash is generated to justify opening and removing ash in the manner indicated in FIG. 6. v

lt should be noted, that the materials of construction are all quite inexpensive, the chamber or casing is constructable from heat resistant metal such as molybdenum steel or the like and the attachments are either mechanically fastened or welded in place. Also, the means for setting up the incinerator is quite simple, it being contemplated that the incinerator can easily be transported from one place to another.

Although the present invention has been illustrated and described in connection with a single example it should be understood that this is illustrative of the invention and is by no means restrictive thereof. It is reasonably to be expected that those skilled in the art can make numerous revisions and adaptations and it is intended that such revisions and adaptations will be included in the scope of the following claims as equivalents of the invention.

What I claim is:

1. An improved incinerator comprising a cylindrical housing defining an internal substantially cylindrical imperforate combustion chamber, a charge door having a hinged mounting on said housing and adapted to cover a charge opening, spaced pedestal members for supporting opposite ends of said housing, an injector burner positioned at one end of said housing, means for supporting the burner to direct the flow generally parallel to the base of the incinerator and located below the midportion of the housing, said injector burner being adapted to emit a conical flame under pressure and effective for engulfing the product to be burned and extending its heating throughout the length of said housing, a discharge opening at the end of said housing opposite said burner and including a closure hingedly mounted on said housing and adapted to be opened and closed for removing ash, and a stack surmounting said housing and disposed at the end of said housing oppositely to said injector burner and including a vent opening for providing a gaseous discharge consisting of the oxidation product of the organic material received within said housing.

' 2. The apparatus in accordance with claim 1 wherein said housing includes a rake having a semicircular plate, and handle which is adapted to extend within the interior of said housing and to scrape the ash out of the interior of said housing and through the ash discharge opening.

3. The apparatus in accordance with claim 1 in which the interior of the combustion chamber is maintained at substantially atmospheric pressure during the combustion operation.
