Abstract
Abstract An apparatus for rolling newspapers or the like into logs for burning is shown. A foot-operated electric motor is securely mounted on a work surface. Connected to the motor and parallel to the work surface is a rectangular shaft removeably supported on the opposite end thereof. The rectangular shaft has two longitudinally tapered halves slideable along the taper therebetween to reduce the effective cross-sectional diameter of the rectangular shaft. By turning the motor ON and supplying paper to the rectangular shaft, the paper is wrapped and periodically taped into position. After a paper log is formed, a prying device anchored to the work surface slideable moves one of the tapered halves with respect to the other tapered half along the taper therebetween. The movement reduces the cross-sectioned diameter of the rectangular shaft thereby releasing the paper log formed thereon. The paper log is slid to the left and removed from the rectangular shaft as a spring loaded hinge pivots out of the way.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
145 words
An apparatus for forming paper logs from sheets of paper comprising: a work surface; motor means stationarily mounted with respect to work surface; shaft means connected to and turned by said motor means, said shaft means extending over said work surface, said shaft means having a first and second longitudinally tapered half, said first longitudinally tapered half being longitudinally stationary, said second longitudinally tapered half being slideably attached to said first longitudinally tapered half with a taper therebetween and slideable along an axis of said shaft means, movement of said second longitudinally tapered half in a first direction along said axis increasing cross-sectional diameter of said shaft means and movement in a second direction along said axis decreasing said cross-sectional diameter of said shaft means; said sheets of paper being wrapped around said shaft means turned by said motor means to form said paper logs.
Claim 2
Independent Claim
145 words
An apparatus for forming paper logs from sheets of paper comprising: a work surface; motor means stationarily mounted with respect to work surface; shaft means connected to and turned by said motor means, said shaft means extending over said work surface, said shaft means having a first and second longitudinally tapered half, said first longitudinally tapered half being longitudinally stationary, said second longitudinally tapered half being slideably attached to said first longitudinally tapered half with a taper therebetween and slideable along an axis of said shaft means, movement of said second longitudinally tapered half in a first direction along said axis increasing cross-sectional diameter of said shaft means and movement in a second direction along said axis decreasing said cross-sectional diameter of said shaft means; said sheets of paper being wrapped around said shaft means turned by said motor means to form said paper logs.
Claim 3
Dependent Claim
40 words
The apparatus as given in claim 1 comprising a moveable support means attached to said work surface for rotably supporting a second end of said shaft means, a first end of said shaft means being connected to said motor means.
Claim 4
Dependent Claim
43 words
The apparatus as given in claim 2 wherein said moveable support means is spring loaded to allow said paper log formed on said shaft means to be slideably removed from said second end of said shaft means by pivoting said moveable support means.
Claim 5
Dependent Claim
32 words
The apparatus as given in claim 3 comprising tape dispensing means attached to said work surface, said tape dispensing means periodically supplying tape to said sheets of paper forming said paper log.
Claim 6
Dependent Claim
37 words
The apparatus as given in claim 2 wherein said shaft means is generally rectangular with slots in said first and second longitudinally tapered halves, said slots having connecting means extending therethrough for slideably connecting said halves together.
Claim 7
Dependent Claim
45 words
The apparatus as given in claim 5 comprising prying means pivotally connected to said work surface, said prying means being constructed and arranged to engage and slide said second longitudinally tapered half in said second direction to decrease said cross-sectional diameter of said shaft means.
Claim 8
Dependent Claim
56 words
The apparatus as given in claim 6 comprising a collar around said shaft means for said engaging and sliding of said second longitudinally tapered half, said collar surrounding a threaded shaft connected to an end of said first longitudinally tapered half and said motor means, nut means on said threaded shaft for aiding said prying means.
Claim 9
Independent Claim
109 words
A method of forming paper logs from sheets of paper consisting of the following steps: energizing a motor to turn a shaft connected thereto, said shaft having a first and second longitudinally tapered half slideably connected together along a taper therebetween; feeding said sheets of paper to said turning shaft for rotation thereon; periodically taping said sheets of paper to maintain a tight roll on said turning shaft; first sliding said second longitudinally tapered half in a first direction along said taper to reduce cross-sectional diameter of said shaft; and second sliding of said paper log formed by said sheets of paper off a first end of said shaft.
Claim 10
Independent Claim
109 words
A method of forming paper logs from sheets of paper consisting of the following steps: energizing a motor to turn a shaft connected thereto, said shaft having a first and second longitudinally tapered half slideably connected together along a taper therebetween; feeding said sheets of paper to said turning shaft for rotation thereon; periodically taping said sheets of paper to maintain a tight roll on said turning shaft; first sliding said second longitudinally tapered half in a first direction along said taper to reduce cross-sectional diameter of said shaft; and second sliding of said paper log formed by said sheets of paper off a first end of said shaft.
Claim 11
Dependent Claim
26 words
The method given in claim 8 wherein said first sliding step includes pushing against an end of said second longitudinally tapered half by a prying means.
Claim 12
Dependent Claim
47 words
The method given in claim 9 wherein said first sliding step further includes nut means connected on a threaded portion of a second end of said shaft, said nut means being constructed and arranged to aid said prying means in pushing against said second longitudinally tapered half.
Claim 13
Dependent Claim
31 words
The method given in claim 8 including a first step of moving said second longitudinally tapered half in a second direction along said taper to increase cross-sectional diameter of said shaft.
Claim 14
Dependent Claim
51 words
The method given in claim 11 wherein said second sliding step includes pivoting support means away from said first end of said shaft as said paper log is removed, said support means being spring loaded to return to support said first end of said shaft after removal of said paper log.
