3 Claims.

This invention relates to improvements in Waste material consuming structures which are also commonly referred to as garbage incinerators,rand has for its general object to ,provide amaterial projected from. the drying shelf becomes` lodged next upon the said steps before being prostructure.

A further object of the invention is to provide means whereby the said steps 4are caused to be relatively positioned, by operation of a hand lever, disposed exteriorly of the structure, to form a continuous inclined surface down which lthe material slides by gravity upon the grate, The means whereby the said steps are positioned to fo-rm'the said slide, are manipulable also by the said hand leverto be shaken to the degree necessary to agitate the waste material and thus promote clearance of said stepsy and deposit of same upon the grate.

Another object of the invention is to provide means whereby vapor arising from the usually moist or wet material deposited upon the drying shelf is caused to be admixed with products of combustion passing from the grate into the chimney ue of the structure.

Other objects of the invention are pointed out particularly in the following description or will.

be readily comprehended therefrom.

A suitable embodiment of the invention is illustrated in the accompanying drawings wherein:-

l is a vertical longitudinal sectional view of a waste material burner constructed in accordance Ywith the invention.

Figs. 2 and 3 are vertical transverse sectional views of t e same taken on the single section line 2 2 and 3-3 of Fig. l looking in opposite directions from the vertical plane indicated thereby. v

Figs. 4 and 5 are .plan sectional views taken on the lines Ll-i 'and 5 5, respectively, of Fig. 1.

The structure comprises a rectangular housing composed, preferably, of an outer metal casing which includes a floor plate I supported in partv upon a channel bar 2,along the rear edge, a series of T-bars 3 between its front and rear edges, and suitably along its front edge, there being a 1 free space between the oor plate and the surface upon which the structure is supported by the

aforesaid elements

2 and 3, which is` open at its end along the side-walls of the structure.

The floor plate supports a series of refractory tiles 4, and the vertical walls are lined in part and to the greatest extent possible, with a suitable plastic lining 5 and, inwardly of the latter, with refractory tiles 6.

The grate 7 of the structure is disposed at an elevation above the tile ocr 4, andis spaced from the front sheet metalqwall and also to a far greater extent from the rear tile wall.

The grate is continuous between the side tile` walls and is supported at its inner end upon the lower ends of side plates 8 which are secured rigidly,. infany suitable manner, to the side walls of the structure and are held in Contact with the tile 6 lining the latter, l

Pivotallysecured to the plates 8 is a series of flat plates 9p The latter are disposed at respectively different elevations to simulate a stairway leading from a point near the inner end portion of the grate 1 to a point near the rear wall of the housing, the pivotal axes of said plates 9 being disposed in a plane extending at an angle of approximately forty-five degrees to the horizontal plane of the grate 1. f

Ar rigid plate I0, equipped with an angularr flange II, is disposed between Vthe inner end of the grate 'I and the lowest plate 9. Another angularly` disposed plate I2 is disposed above the uppermost plate 9, both plates Il! and I2 being secured at theirl endsto the plates Plates S, Il! and I2 constitute a support for waste material delivered from above, as will hereinafter be described.

Each plate 19 is equipped with a depending arm I3 which is secured pivotally at its lower end to aflat bar I4. The latter is secured pivotally to one end of a link I5 which, at its other end, is

secured pivotally to the lowerarm of a bellcrank 3 will be tipped to the dotted line position of Fig. 1, with the then lower edge portions of respective plates 9 overlapping the next lower plates and the flange Il of the plate 3, said lower edges of the plates 9 being comb-like and thus providing air ducts to promote drying of material deposited upon the plates 9 when the latter are disposed horizontally, and for passage of some air through the uncovered portions of the recesses when said plates are disposed in their dotted line positions.

The ash pit 20, below the grate, derives air through the customary and usually damper controlled openings (not shown) in the door I8. The door I8 may be a duplicate of the door 23 which is equipped with an inner perforated plate 23a spaced from the outer and peripheral walls of said door 23, such doors being of conventional type.

The forward end of the grate 1 is secured to the inclined bracket plate 22 which is secured rigidly, in a suitable manner, to the front metal wall of the housing, as, for example, to the frame of the door 23. The latter is also hinged to said front wall and is, in all respects, a substantial duplicate of the door I8.

Material, such as waste wood, paper and the like may be introduced through the opening controlled by the door 23, usually to start a fire in the structure for pre-heating purposes, and for this same purpose and to effect ignition of fuel disposed upon the grate 1, a pair of gas burners 24 (Fig. 5) are provided, as shown, which are connectible, suitably, with the fuel gas supply pipes of the building.

At an elevation above the grate 1, a horizontally disposed shelf 25 is provided which extends over the entire width of the structure, which, for convenience, will be referred to hereinafter as a furnace.

The vertical plane of the inner edge of the said shelf is oiTset from the vertical plane of the inner end of the grate 1 only slightly, said shelf being supported by a pair of members 26 and 21.

A rectangular frame 2B having peripheral walls of substantially Z-shaped section supports a refractive member 29 which may consist of a suitable refractive plastic which is introduced into said frame when the latter is inverted with its cover plate 30 providing a support for the said plastic material.

Said cover plate 30 is dished slightly and presents peripheral ilanges to rest upon the supports 25 and 21 and end supports secured to the side walls or otherwise provided.

It will be noted that the support 21 is provided with vent openings 3| (Fig. 2).

The top wall 32 of the furnace is disposed at an angle of forty-five degrees to the front wall and is equipped with a door controlled opening through which moist and wet waste material is dropped upon the shelf 25, the door 33 controlling said opening is, in all respects, similar to the door I9 and is hinged at top.

The portion of the top wall 32 above the door hinge covers a triangular chamber 34 bordered by the curtain wall 35 and a bottom wall 36, both walls 35 and 3B being composed of refractory tiles and suitably supported.

The wall 35 constitutes also a wall of the chimney ue 31. Below the lower end of the latter, a water heater 38 is mounted which comprises a lower water intake duct and an upper duct connected with each other by the inner end duct 39 (shown in dotted lines in Fig. 3) the pipes.

(iii

40 and 4l being connectible in a customary manner with the cold water supply system and a hot water storage tank. The front and rear walls of the water heater are flush with the faces of the wall 35, the said rear wall being equipped with a series of vanes 42 projecting into the chimney ue.

The water heater 38 is suitably supported upon the side wall of the casing and constitutes a support for the curtain wall 35, and thus the latter and said heater 38, in commotion with said side walls and rear wall of the structure, provide the chimney flue.

The said curtain wall, including the said water heater, is disposed, at its lower edge, appreciably from the shelf 25. The latter becomes very hot and thus vaporizes the water contained in the material disposed upon said shelf which would rise to fill the space between the curtain wall and the top intake door. However, air entering said space through openings in said door becomes admixed with said vapors and is caused to become humidified and admixed with products of combustion passing into and through the chimney flue and thus promotes combustion of combustible gases and soot within said chimney flue.

In the use of the structure, the dry or substantially dry material disposed upon the shelf 25 is easily projected upon the plates 9 by means of a shovel, spade or other suitable implement and may remain there for complete drying or storage and then caused to pass downwardly toward and upon the inner end portion of the grate 1 by gravity by operating the lever I6 to dispose the plates 9 in the dotted line position of Fig. 1, this descent of the material being aided by effecting a shaking or slight movement of said plates 9 from and to the said dotted line position. Spreading of said material over the grate thereafter may be eiected by a hoe, rake or other implement projected through the door 23.

I claim as my invention:

l. A waste material consuming structure comprising a housing, means dividing the interior of the housing into an ash pit and an upper space, said means including a horizontal grate in the front half of the housing and a stepped waste material support extending upwardly and rearwardly, at an angle of about 45, from the rear end of said grate to the rear wall of the housing and presenting air passages connecting the ash pit to said upper space, doors in the front wall of the housing above and below the grate, a stationary shelf extending across the front half of the interior of the housing above the upper of the aforesaid doors, a chimney ue in the upper rear portion of the housing above said waste material support, said flue including a curtain wall parallel to the front wall of the housing and having its lower edge spaced a substantial distance from said shelf, and a door in the housing directly abovev the shelf to admit waste to be consumed.

2. A waste material consuming structure as set forth in claim 1, wherein the curtain wall of the chimney flue is hollow and is provided with inlet and outlet openings for water to be heated.

3. The combination with the housing of a waste material consuming structure having an ash pit, of a horizontal grate in and spanning the front half of the housing above the ash pit; a support for waste material inclined upwardly and rearwardly from the rear end of the grate to the rear wall of the housing, said support including a series of plates hinged to swing about transverse horizontal axes between horizontal, spaced positions to create a stepped formation presenting air passages connecting the ash pit to the space above said plates and positions wherein they form a downwardly sloping surface; means to rock the plates; a stationary shelf extending across the front half of the interior of the housing above and in spaced relation to the grate; doors in the front of the housing for the admission of material to the shelf and grate, respectively; and a chimney ue in the top of the housing above said inclined support.
