EDWARD w. HACKER mvemm INCINERA'IOR ORSIMILAR ARTICLE FIELD OF INVENTION The present invention relates to an incinerator and more particularly to an incinerator operable to destroy combustible products and to filter exhaust air contaminants and odors.

DESCRIPTION OFTI'IE PRIOR ART Incinerators generally known in the-prior art generally comprise a large combustion chamber into which is deposited a quantity of combustible products intended to be destroyed. The combustible products to be destroyed are usually accumulated until a substantial vquantity may be burned at one time, causing an unsightly and unsanitary collection of waste products. Although some incinerators are provided with filters, substantial amounts of airborne contaminants are released into the atmosphere. I

Accordingly, it is an object of the present invention to provide an incinerator in which a single combustible product may be destroyed at a time and thereby avoid accumulations of waste material.

Another object of the present invention is to provide a simply constructed incinerator which is inexpensive to operate, and which may be-placed in convenient locations near the point of disposal, like waste cans or baskets.

A further object of this invention is to provide in combination with incinerating means an air purifying and filter means.

Generally the incinerator of the present invention comprises a boxlike housing having hinged topand bottom access panels on the housing, an incineratorgrid and a resistence heating coil juxtapositioned in the housing and an exitway in the housing to exhaust the products of combustion. Filters are preferably disposed in the exitway to prevent escape of airborne contaminants and odors.

A more thorough and comprehensive understanding may be had from the detailed description of the preferred embodiment when read in connection with the drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the incinerator of this invention as seen from the top left side and is shown with the access door thereof open.

FIG. 2 is a cross section fragmentary plan view of the invention taken generally along lines 2-2 of FIG. 1.

FIG. 3 is a cross section elevational view of this invention with one of the walls of the housing removed.

FIG. 4 is a cross section elevational view of the invention with an adjacent wall to that wall removed in FIG. removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings and more particularly to FIG. 1 which shows the incinerator or similar article of the present invention in a top perspective view and generally designated by the numeral 10. The incinerator 10 includes a boxlike housing 11 having an access door 12 suitably connected by a hinge 13 at the uppermost terminal side of housing 11 and a panel 14 connected by a hinge 15 at the opposing lowermost terminal side of housing 11. The sidewalls of the housing 11 preferably include an insulating material. A sealing gasket (not shown) may be provided about the terminal edges of the housing 11 contiguous with the door 12 to seal the housing during the incineration process as hereinafter later described. An intermediate panel 16 integral with the uppermost terminal sides of the housing 11 is provided and disposed so that the panel 16 projects upwardly from the housing 11 to engage with the door 12. In this manner the quantity of ambient air which may infiltrate the housing may be limited.

The intermediate panel [6 is provided with a pair of biparting closures I7 and 17' suitably connected by respective hinges l8 and I8 havingsprings I9 and 19' shown to advantage in the cross section elevational side view of the FIG. 4.

The biparting closures l7 and "17' are operable to'provideaqcess for depositing combustible products'in the housingll while providing, at the same time means 'to safely limit access of hands into the housing 1 1.

The housing] 1 is provided with a latching means 20 which may include a commonly known mechanically timed switch 'v (not shown) electrically connected to a resistance heating. coil 21 disposed in the'housing 11. The latching means 20 isen-"' 11 and is more durable.

grid 23 made from ceramic materialsuitable heats toaid in the distruction of combustible material deposited 'in the housing Referringriow to the fragmentary cross section plan view of I the FIG. 2 and the cross section'elevati'onal view of FIG. 3 with one wall-removed, the housing I! is provided with a'iiin- 'termediate wall 24 including a vented-exitway 25. The

chamber formed by intermediate wall 24 and the wall of hous-" ing 11 provides a draft'plenum which tends to cause the.car bon monoxide gases to be drawn away from the burning product to permit the product to continue to burn. It has been found to advantage in practice to provide'a charcoal filter in the exitway. Of further advantage is a commonly known electrostatic filter such as 7 shown at *26' and disposed in the chamber 27 formed by the intermediate wall 24 and one of the terminal walls of the housing 1 l which includes an exitway 2 8.

In operation the door l2'is raised and combustible products intended to 'be destroyed maybe deposited through closures l7 and 17. onto the grid 235When the door 12 is closed andthe latch 20 is engaged with the lock22'on'the door 12. The resistance l'ieating coil-21 and the electrostatic filter 26 are electrically'energizedfAs the coil is heatedfthe combustible product deposited in the housing'dl is'caused to burn. The heat in the housing-ll causesadraftfromthehousing 11 through chamber 27 and consequently through the exitway 25, the electrostatic filter 26, and th'e'exitway 28. The exhaust air is thereby filtered of contaminants'and odor. I

The FIG. 4 shows to advantage the hinged panel 14. The panel 14 is provided withalock'29fshown'toadvantage in FIG. 1. B unlocking the lock 29 and opening the panel 14 access to the housing 11 may be had for cleaningand maintenance.

Having thus described in detail a preferred apparatus which embodies the concepts and principles of the invention and which accomplishes the various objects,purp'oses, and aims thereof, it is to be appreciated and will be apparent to those skilled in the art, that many physical ch'an'gescould be made in the'apparatus without altering the inventive concepts and principles embodied therein. Hence, it is intended that the scope of the invention be limited only to the extent indicated in the appended claims.
