Abstract

Abstract An apparatus for manufacturing paper fire logs, the apparatus comprising a solution-containing reservoir above which is mounted a removable slotted, slit or split shaft through which the end of newspaper, magazine or the like is placed (and the shaft rotated either by a motor or manually) causing the paper to be rolled or wound upon the slotted shaft as it is passed through the solution in the reservoir, the paper being fed to the shaft along a tilting platform which is supported upon a knife edge for rotational purposes, one edge of the platform being bias against the roll of paper upon the slotted shaft but accommodating opposite rotation as the diameter of the paper upon the shaft increases. The wet paper fire log is removed from the apparatus by separating the slotted shaft from the remainder of the apparatus, squeezing the paper fire log and allowing it to dry.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 113 words
An apparatus for making paper fire logs comprising: an open top tank in which a liquid is placed; an axially slotted shaft removably bridging between opposed walls of the tank; means removably and rotatably supporting the slotted shaft in said bridging position; platform means disposed to one side of the slotted shaft and spanning toward the slotted shaft along which paper is linearly displaced to and thereafter wound upon the slotted shaft; means for rotating the slotted shaft while in said bridging position; whereby paper the leading edge of which is received at the slot of the shaft is linearly displaced along the platform means, into the liquid and wound upon the shaft.
Claim 2
Independent Claim 113 words
An apparatus for making paper fire logs comprising: an open top tank in which a liquid is placed; an axially slotted shaft removably bridging between opposed walls of the tank; means removably and rotatably supporting the slotted shaft in said bridging position; platform means disposed to one side of the slotted shaft and spanning toward the slotted shaft along which paper is linearly displaced to and thereafter wound upon the slotted shaft; means for rotating the slotted shaft while in said bridging position; whereby paper the leading edge of which is received at the slot of the shaft is linearly displaced along the platform means, into the liquid and wound upon the shaft.
Claim 3
Dependent Claim 54 words
An apparatus according to claim 1 wherein said means supporting the slotted shaft comprise a bushing at one location and a motor shaft at the other and wherein said rotating means comprises a motor whereby the slotted shaft may be axially removed from the apparatus while restraining the roll of paper previously wound thereon.
Claim 4
Dependent Claim 14 words
An apparatus according to claim 1 wherein said rotating means comprises a manual crank.
Claim 5
Dependent Claim 27 words
An apparatus according to claim 1 wherein said shaft has material missing from the interior thereof whereby the effective diameter may be constricted to accommodate log removal.
Claim 6
Dependent Claim 43 words
An apparatus according to claim 1 wherein said platform means is pivotally carried by the apparatus and exerts a force against the paper upon the slotted shaft to aid in correctly winding the paper upon the slotted shaft, the liquid aiding in consolidation.
Claim 7
Dependent Claim 34 words
An apparatus according to claim 1 wherein said supporting means comprise bushing means whereby the slotted shaft may be axially removed from the remainder of the apparatus while restraining the paper previously wound thereon.
