Abstract
Abstract An incineration device for rubbish or industrial refuse, comprising a rotating furnace casing and an ash receiver which comprises a casing concentric with the furnace casing, closed at both ends and extending beyond the discharge end of the furnace casing, and one helical blade rotating with said furnace casing and arranged in the space between the ash-receiver casing and the furnace casing for driving the ashes away from their spot of discharge in the ash receiver.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
211 words
An incineration device, in particular for rubbish and other household or industrial refuse, of the type comprising a rotatable furnace casing having an axis of revolution about which the casing is rotatable, said casing having one end for the introduction of the said rubbish or refuse and an opposite end for discharge of ashes and incineration residues, an ash-receiver comprising a second casing for receiving said ashes and incineration residues discharged from the opposite end of the furnace, said second casing being concentric with the furnace casing and closed at its opposite ends and being of a length longer than the furnace casing whereby to extend beyond the discharge end of the furnace, said second casing being provided with at least one helical blade in at least a portion of the space between the two concentric casings and being rotatable in opposite directions in one of which, in cooperation with said blade, said ashes and residues are moved toward said one end of said furnace, said second casing being provided adjacent the discharge end of the furnace with at least one door permitting discharge of said ashes and residues from said second casing upon reversing the direction of rotation of said second casing relative to said one direction of rotation thereof.
Claim 2
Dependent Claim
211 words
An incineration device, in particular for rubbish and other household or industrial refuse, of the type comprising a rotatable furnace casing having an axis of revolution about which the casing is rotatable, said casing having one end for the introduction of the said rubbish or refuse and an opposite end for discharge of ashes and incineration residues, an ash-receiver comprising a second casing for receiving said ashes and incineration residues discharged from the opposite end of the furnace, said second casing being concentric with the furnace casing and closed at its opposite ends and being of a length longer than the furnace casing whereby to extend beyond the discharge end of the furnace, said second casing being provided with at least one helical blade in at least a portion of the space between the two concentric casings and being rotatable in opposite directions in one of which, in cooperation with said blade, said ashes and residues are moved toward said one end of said furnace, said second casing being provided adjacent the discharge end of the furnace with at least one door permitting discharge of said ashes and residues from said second casing upon reversing the direction of rotation of said second casing relative to said one direction of rotation thereof.
Claim 3
Dependent Claim
211 words
An incineration device, in particular for rubbish and other household or industrial refuse, of the type comprising a rotatable furnace casing having an axis of revolution about which the casing is rotatable, said casing having one end for the introduction of the said rubbish or refuse and an opposite end for discharge of ashes and incineration residues, an ash-receiver comprising a second casing for receiving said ashes and incineration residues discharged from the opposite end of the furnace, said second casing being concentric with the furnace casing and closed at its opposite ends and being of a length longer than the furnace casing whereby to extend beyond the discharge end of the furnace, said second casing being provided with at least one helical blade in at least a portion of the space between the two concentric casings and being rotatable in opposite directions in one of which, in cooperation with said blade, said ashes and residues are moved toward said one end of said furnace, said second casing being provided adjacent the discharge end of the furnace with at least one door permitting discharge of said ashes and residues from said second casing upon reversing the direction of rotation of said second casing relative to said one direction of rotation thereof.
Claim 4
Dependent Claim
211 words
An incineration device, in particular for rubbish and other household or industrial refuse, of the type comprising a rotatable furnace casing having an axis of revolution about which the casing is rotatable, said casing having one end for the introduction of the said rubbish or refuse and an opposite end for discharge of ashes and incineration residues, an ash-receiver comprising a second casing for receiving said ashes and incineration residues discharged from the opposite end of the furnace, said second casing being concentric with the furnace casing and closed at its opposite ends and being of a length longer than the furnace casing whereby to extend beyond the discharge end of the furnace, said second casing being provided with at least one helical blade in at least a portion of the space between the two concentric casings and being rotatable in opposite directions in one of which, in cooperation with said blade, said ashes and residues are moved toward said one end of said furnace, said second casing being provided adjacent the discharge end of the furnace with at least one door permitting discharge of said ashes and residues from said second casing upon reversing the direction of rotation of said second casing relative to said one direction of rotation thereof.
Claim 5
Dependent Claim
21 words
A device according to claim 1, wherein the first and second casings and the said helical blade form an integral structure.
Claim 6
Dependent Claim
40 words
A device according to claim 2, wherein the axis of revolution of the furnace is inclined with respect to a horizontal line, said furnace having upper and lower ends forming respectively the said one end and the said discharge ends.
Claim 7
Dependent Claim
29 words
A device according to claim 1, wherein the said at least one door is a removable panel forming a part of the second casing and provided with locking means.
