4 Claims, 3 Drawing Figures RUBBISH DISPOSAL INSTALLATION It has been the custom in garden apartment and other two and three story buildings to install what is known as Class II incinerators which consist of a vertical chimney having a grate and fire door at the bottom and doors on each floor of the building so that rubbish may be disposed of by dumping it down the chimney.

The rubbish to be disposed in such buildings consists of all forms of household waste and garbage much of which is not readily combustible, and some, such as cans and bottles are not combustible at all. It has been necessary, therefore to supply heat by appropriate fuel burners to consume as much as is practical of the refuse. The residuum must then be removed from the combustion area and ash pit and placed in disposal containers from which it is transferred to trucks for dumpmg.

These Class II incinerators are not efficient nor economical of fuel, time or labor, and, under present conditions of increasing population density requiring anti-pollution measures to be put into operation use of Class II incinerators will probably be prohibited in the near future.

One of the reasons in the past for use of such incinerators was that they are inexpensive to install and, while creating smoke etc., they did reduce the weight of refuse to be hauled away by trucks.

It is an object of the present invention to provide a means similar to Class II incinerators in so far as inexpensive installation costs are concerned, either as original equipment or as a kit which a presently installed Class II incinerators may be converted to provide the same convenience to the tenants in the building while eliminating the air pollution, the use of fuel, and to reduce the labor required by the building janitor by elimination of the need to shovel out ash pits and dump the grates as is required in the use of Class II incinerators.

Other and further objects and advantages will appear from the following specification taken with the accompanying drawings in which like reference characters refer to like parts in the several views and in which:

FIG. 1 is a front elevation of the device of the present invention installed;

FIG. 2 is a section on line 22 of FIG. 1; and

FIG. 3 is a section on line 33 of FIG. 1.

The device may be installed in an extant Class II incinerator structure by inserting a lintel above the present fire door that gives access above the grate and removing the wall and doors below this new lintel. The new lintel is shown in FIG. 2 at 10. The mason then will insert track elements 12, one on each side of the flue 14, and one across the rear wall.

This track element is preferably of box construction, rectangular as seen in section, the box portion preferably having overall dimensions such that it fits into masonry as standard sized fire brick would, but any appropriate size may be selected. The flange 16, forming the actual track may, of course be of any appropriate dimension but a projection of 1%inches is considered to be desireable.

A funnel like chute 18 is formed having an outwardly extending flange 20 at its uppermost extremity. This funnel like chute is rectangular at the top and of such a size that the flange 20 overlies the track 16 along the sides, and across the back of flue 14. The front of the chute 18 extends across under the front surface of the flue 14. This would leave an opening between the top of the chute and the lintel 10 which, however, maybe closed by a plate 22 held in position by a clip 24. The bottom edge of plate 22 is spaced slightly above the plane of tracks 16 to permit easy passage of flanges 20 between the track 16 and plate 22. Preferably a stop 26 is fixed on the flange 20 across the front of chute 18 and contacts plate 22. Since heat is not used in the device, a resilient sealing element similar to Weatherstripping may be used at 26 if desired. To hold chute 18 in position a headed pin, or bolt 28 is dropped into a hole drilled in the track 16. The flange track 16 may be closed adjacent the plane of the lower surface of lintel 10 which will eliminate the need for plate 22.

The lower end of chute 18 is shown as being cylindrical and of a diameter substantially that of a rubbish or waste handling container 30. Chute 18 could, of course, be rectangular at its lower end if rectangular rubbish containers 30 are to be used such as might be convenient for use in connection with refuse baling machinery to which the rubbish collected in container 30 is to be delivered.

Surrounding the lower end of chute 18, whether cylindrical or rectangular, is a vertically movable telescoping element 32 that is slightly larger than chute 18 so it can be raised and lowered with respect to chute 18. To the lower end of telescoping element 32 a closure flange 34 is fixed which seats on but does not grip the top edge of refuse container 30.

To raise and lower closure 34 two levers 36 are pivoted, at each side, to a frame 37, by pins 38. The telescoping element 32 is provided at each side with a pin 40 that engages an aperture 41 in lever 36. A bar 42 connects the ends of levers 36 so that the two levers are actuated simultaneously by depression of handle 42 to raise closure 34 from container 30 so that the container 30 may be removed, and an empty container be put in position and closure 34 brought down to close the empty container by release of bar 42.

In operation of a garden type apartment having, say ten refuse collecting devices as described above the janitor needs only to replace filled, or partly filled refuse containers 30 periodically by pressing down on bar 42, pulling the container 30 out from under chute l8 and pushing a replacement container into position. The refuse in the filled container may be collected in the usual way by trucks, or may be baled before it is picked up by truck for disposal at some distant point.

There is, of course, no smoke, ashes, fumes, or vapors developed in this refuse disposal system, the closures 34 fits snugly preventing spillage of refuse and preventing access to the refuse .in container 30 by rodents. If, however, a glowing cigarette or the like should accidentally be dropped down flue 14, the tightness of the device will prevent more than a minimum of air to be drawn into the flue so any blaze that might break out will be smothered, but even in case a more substantial flame were developed, the fire will be contained in flue 14 and can be readily extinguished.

Having thus disclosed the invention, I claim:

1. A waste disposal unit for use in buildings having masonry waste disposal chutes such as are used with Class II incinerators said unit comprising a lintel to support the masonry of the front wall of said chute, a metal frame set in said masonry, said frame being provided with a track flange extending into said chute along the two sides and the back of said chute at a level below the bottom of said lintel, a hopper element having a peripheral outwardly extending flange at its uppermost extremity adapted to engage said track flange along the sides and back of said chute, and to extend across the front of said chute below said lintel, said hopper element extending smoothly downwardly and inwardly to a relatively short vertical portion of a size and shape conforming generally to a waste disposal container, a vertically movable element slidingly positioned about said vertical portion of said hopper, said movable element being provided at its periphery with a rim providing a generally horizontal flange to engage the top edge of a waste container and a downwardly extending flange to extend downwardly about the top edge of said waste container positioned under said hopper element, and operating means to slide said vertically movable element upwardly when it is desired to withdraw a waste container from its position under said hopper and replace it with an empty waste container.

2. The waste disposal unit of claim 1 in which said means to slide said vertically movable element upwardly comprises a frame secured to said hopper, levers pivoted to said frame and to said vertically movable element at diametrically opposed points, and a bar secured to both said levers to simultaneously operate said levers.

3. The waste disposal unit of claim 1 in which said metal frame set in the masonry comprises a body portion having cross section in the form of a rectangle, said track flange being formed as a continuation of one side of said rectangle.

4. The waste disposal unit of claim 3 in which said track flange is positioned below said lintel the distance of the vertical dimension of said body portion of said frame, and a plate element extends across the front of said frame flush with the inner surface of the front wall of said masonry chute to substantially close the vertical space between said lintel and said track, the said outwardly extending flange at the uppermost extremity of said hopper element that extends across the front of said chute having an upwardly extending element along its upper surface to engage the bottom edge of said plate element to close the gap between said flange and said plate element.
