PATENT OFFICE EDWARD W. STR'UBE, OF LONG ISLAND, NEW YORK INCINERA'IOR OHU'IE AND DRAFT APPARATUS Application filed March 29, 1930. Serial No. 439,938.

This invention relates to an incinerator chute and draft apparatus, and its principal object is to provide means whereby garbage and waste material may be'dumped into a chimney passage and conducted into a fire chamber, and means for conducting the exhaust gases of combustion from the said fire chamber into the aforesaid chimney passage where the natural upward draft will convey it to the chimney vent and to the out-door atmosphere.

Another object is to provide means for an under draft from a point below the chute mouth where it may pass freely and clear of any soggy or congested material which may have accumulated in the said mouth when the the incinerator is filled in excess of its normal capacity. 7

Another feature of the invention is a buffer element so positioned as to overlap the vent from the under draft channel, and one, or more deflecting buffers in the combined chimney flue and chute.

Another novel element is an automatic closure which shuts off a receiving hopper from the chimney chute.

A further improvement which adds safety and efficiency to the apparatus is a swinging panel suspended over the discharge mouth of the chute and behind the lower intake door and adapted to prevent the outburst of any material which might be dropping down the chute at a moment when the said intake door had been opened for the dumping of waste matter directly into the incinerator.

The foregoing and other objects and features of the invention will be described in detail in the following specification and 5 claims, and illustrated in the accompanying drawings, in which Fig. 1 shows an incinerator installed in a cellar and adjacent to a combined chimney and chute. The upper portion on the incinerator is shown in section and the chinmey chute and principal elements of the invention, together with portions of the lower structure, are also shown in section to better disclose their construction and the manner in which they function.

Fig. 2 is an enlarged front view taken with in the limits of the line 22 of Figure 1.

Fig. .3 is a section on the line 3-3 of F igure 2.

Fig. 4 is a plan View, partly in section on the line 4-.4 of Figure 3.

Referring mainly to Figure l of the drawings, the apparatus is described as follows:

"A combined chimney and chute passage is shown at 10, the foundation wall of the build ing is seen at11;'earth outside the said wall is shown at 12 and the kitchen floor ofthe building at 113'; the kitchen at 14 and the cellar at 15. It is, of course, not necessary that the intake hoppers should be in a kitchen, although the chimneys into which they open usually pass upward adjacent to that portion of the house.

The apparatus may be installed in conat18; but'for use in apartment houses and such buildings there may be'as many intake hoppers as required for the various floors and living rooms which they serve, the arrangementbeing; in line, one above another.

.Itwill be seen that at the base of the chimney chute, an opening 20 is located and throught-his opening an inclined ofiset element 21 is inserted and secured in position. This inclined element has a lower floor 22 which extends from the chute mouth 23 to a point below the buffer 24 which overlaps it, avent being provided thereunder as seen at 25. This fioor 22 is slightly curved upward at 26 an-dis supported on cross bars 27. Beneath the fioor 22 is provided an under draft passage 28 which draws exhaust air and gases from the fire chamber at a point below the chute mouth 23. Vhen soggy material is piled up in the fire chamber and chute mouth, the draft directly up the inclined chute is greatly obstructed; but when this occurs, the under draft 28 serves to produce efiicient and adequate combustion.

The inclined chute 21 is attached at its base to the top lid 30 of the incinerator, and a direct intake door 31 is provided as shown. Suspended behind this door and over the mouth of the chute element is a swing panel 32 pivotally hung at 33. This swings easily forward, or back to permit of the passage of material into the fire chamber. Should a person open the door 31, at a moment when material was in passage from an upper floor, the said material would strike the panel 32 and be deflected so that it would not burst out of the open door 31. This is also a safety provision, as it prevents the knocking open of the door 31 in case it should have been left insecurely fastened.

The buffer 34 deflects falling material and diminishes the force of the blow when it strikes the floor 22.

An automatic closure door 36 is pivotally hung within each upper intake hopper as that shown at 18. These doors are hung out of the line of the chimney chute and are slightly inclined and rest at their lower extremities against the base of the hoppers. They prevent combustion gases, smoke or the like from entering the rooms when the hopper lids 37 are open, and they also prevent particles of garbage or like material from upper floors, from flying out in the event of such material being in passage at the time when a hopper lid was open.

As indicated by the arrows 38 and 39 respectively, it will be seen that material drops as at 38; while smoke and exhaust gases rise as at 39 through the combined chimney and chute 10 as illustrated in the drawings.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is as follows:

1. In combination with an incinerator and a combined chimney and chute, an oflset element connecting the passage channel of the said chimney and chute with the said incinerator, an inclined floor in the said ofi'set element, an independent draft passage below the said floor and having a vent discharging into the said chimney and chute, and a deflector element positioned above and overlapping the said vent.

2. In an apparatus of the class described, an inclined ofi'set chute element connecting a combined chimney and chute with an incinerator and adapted to conduct material in passage to the combustion chamber of the said incinerator, a. floor in the said offset chute element, an independent draft passage below the said floor, a vent opening from the said independent passage into the said chimney and chute, a buffer element positioned above the said vent and partially overlapping the same, an intake door opening into the baseportion of the said ofi'set chute ele-.

'combu'ston chamber and to discharge the said draft into the said chimney and chute.

Signed at New York city in the county of New York and State of New York this 24th day of March A. D. 1930.

EDWARD W. STRUBE.
