Abstract
Abstract An incinerator has a lower combustion portion preferably equipped with a burner and an upper afterburning portion which can be swung off the lower portion. This upper portion has an upper outlet mouth. A chimney extends alongside the portions and has a lateral flue which opens just above the upper outlet mouth. A collar on the flue controls the amount of air let in at the gap between the flue''s end and the mouth and this collar can be lifted also to swing out the upper afterburning portion for loading the combustibles into the burning chamber. A flap on the chimney below where the flue is connected is biased closed by a weight and, on excessive draft, opens to control this draft.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
100 words
An incinerator assembly, comprising: a two-part housing having a lower combustion portion and an upper afterburning portion, said upper portion having an outlet mouth; an upright chimney alongside said housing; a two-ended flue having one end connected to said chimney and the other end opening downwardly above said mouth while being spaced therefrom across a gap; means enabling displacement of said upper portion out from between said other end of said flue for introducing combustibles into said housing; and draft-regulating means connected to said chimney independently of said flue below said one end for controlling the draft in said housing.
Claim 2
Dependent Claim
100 words
An incinerator assembly, comprising: a two-part housing having a lower combustion portion and an upper afterburning portion, said upper portion having an outlet mouth; an upright chimney alongside said housing; a two-ended flue having one end connected to said chimney and the other end opening downwardly above said mouth while being spaced therefrom across a gap; means enabling displacement of said upper portion out from between said other end of said flue for introducing combustibles into said housing; and draft-regulating means connected to said chimney independently of said flue below said one end for controlling the draft in said housing.
Claim 3
Dependent Claim
22 words
The incinerator assembly defined in claim 1, further comprising a base plate, said chimney and said housing being mounted on said plate.
Claim 4
Dependent Claim
30 words
The incinerator assembly defined in claim 2, further comprising a vertically displaceable collar shiftable over said outlet mouth and adapted to surround said gap, and means for displacing said collar.
Claim 5
Dependent Claim
20 words
The incinerator assembly defined in claim 3 wherein the last-mentioned means is adjustable to control air inflow to said flue.
Claim 6
Dependent Claim
46 words
The incinerator assembly defined in claim 4 wherein said chimney is formed with an opening below said one end of said flue and said draft-regulating means comprises a pivotal flap in said opening, and means adjustably biasing said flap for controlling air inflow through said opening.
Claim 7
Dependent Claim
20 words
The incinerator assembly defined in claim 1, further comprising a burner in said lower portion for igniting combustible material therein.
Claim 8
Dependent Claim
144 words
The incinerator assembly defined in claim 1, further comprising a base plate, said housing being vertically elongated and mounted on said base plate, said upper portion of said housing being formed with an upwardly converging frustoconical hood portion terminating at a cylindrical tubular neck defining said mouth, said neck having an axis perpendicular to said plate, said chimney being mounted directly on said plate with a vertical axis perpendicular to the plate and parallel to the first-mentioned axis, said flue having a downwardly extending cylindrical tube axially aligned and coextensive with said neck and constituting said other end of said flue, a vertically displaceable collar on said tube having a lower position wherein said collar surrounds said gap and an upper position wherein said neck clears said collar for said displacement of said upper portion, and mechanism for shifting said collar between said positions.
Claim 9
Dependent Claim
99 words
The incinerator assembly defined in claim 7 wherein said collar surrounds said gap in said lower position while communicating between said gap and the surrounding atmosphere with adjustable airflow cross section, said means enabling displacement of said upper portion including pivot means interconnecting said upper and lower portions and means for swinging said upper portion relatiVely to said tube and said lower portion about said pivot means, said lower portion being formed with a burner for fuel-and-air combustion in said lower portion, said upper and lower portions being provided with apertures open to the atmosphere for sustaining combustion therein.
Claim 10
Dependent Claim
29 words
The incinerator assembly defined in claim 8 wherein said mechanism includes a lever engaging said collar and a pull rod spaced from said housing and connected to said lever.
Claim 11
Dependent Claim
55 words
The incinerator assembly defined in claim 9 wherein said draft-regulating means includes a downwardly extending branch having an axis parallel to the axis of said chimney and formed with an opening, a flap pivotally mounted on said branch for adjusting the effective cross section of said opening, and an adjustable counterweight connected to said flap.
