Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
125 words
A device for coiling sheet material to form a combustible log, comprising a base having a top side, posts mounted to the top side of the base at opposite ends, bearing members mounted on the posts for vertical sliding movement thereon perpendicular to the base said bearing members containing bearing openings, a spindle rotatably mounted in said openings with its axis parallel to the base for rotation about an axis parallel to the base and for movement perpendicular to the base, spring means yieldably resisting movement of the bearing members perpendicular to the base, means on the spindle for connecting an end of the sheet to be coiled thereon to the spindle, and a crank at one end of the spindle for effecting rotation thereof.
Claim 2
Independent Claim
125 words
A device for coiling sheet material to form a combustible log, comprising a base having a top side, posts mounted to the top side of the base at opposite ends, bearing members mounted on the posts for vertical sliding movement thereon perpendicular to the base said bearing members containing bearing openings, a spindle rotatably mounted in said openings with its axis parallel to the base for rotation about an axis parallel to the base and for movement perpendicular to the base, spring means yieldably resisting movement of the bearing members perpendicular to the base, means on the spindle for connecting an end of the sheet to be coiled thereon to the spindle, and a crank at one end of the spindle for effecting rotation thereof.
Claim 3
Dependent Claim
19 words
A device according to claim 1, wherein the posts are detachably secured at their lower ends to the base.
Claim 4
Dependent Claim
15 words
A device according to claim 1, wherein the crank is detachably connected to the spindle.
Claim 5
Dependent Claim
22 words
A device according to claim 1, wherein the spindle may be slidingly removed from the bearing members by axial movement relative thereto.
Claim 6
Independent Claim
154 words
A device for coiling sheet material to form a combustible log, comprising a rigid, substantially rectangular base having a top side, said base having at its top side at opposite ends transversely spaced openings, means at the opposite ends of the base comprising posts fixed at their lower ends in the openings at one side and brace members connected at one end to the upper ends of the posts and fixed at their other ends in the openings at the other side, said posts being perpendicular to the base, bearing members slidable vertically on the posts, coil springs mounted on the posts with their lower ends abutting the bearing members, means fixing the upper ends of the springs so that upward displacement of the bearing members is opposed, and a spindle rotatably mounted in the bearing members parallel to the base for rotation about its longitudinal axis to wind the sheet into a coil.
Claim 7
Independent Claim
154 words
A device for coiling sheet material to form a combustible log, comprising a rigid, substantially rectangular base having a top side, said base having at its top side at opposite ends transversely spaced openings, means at the opposite ends of the base comprising posts fixed at their lower ends in the openings at one side and brace members connected at one end to the upper ends of the posts and fixed at their other ends in the openings at the other side, said posts being perpendicular to the base, bearing members slidable vertically on the posts, coil springs mounted on the posts with their lower ends abutting the bearing members, means fixing the upper ends of the springs so that upward displacement of the bearing members is opposed, and a spindle rotatably mounted in the bearing members parallel to the base for rotation about its longitudinal axis to wind the sheet into a coil.
Claim 8
Dependent Claim
15 words
A device according to claim 5, wherein the braces are inclined relative to the base.
Claim 9
Dependent Claim
17 words
A device according to claim 5, wherein the upper ends of the legs and braces are integral.
Claim 10
Dependent Claim
21 words
A device according to claim 5, wherein the lower ends of the legs and braces are detachably bolted to the base.
Claim 11
Dependent Claim
32 words
A device according to claim 5, wherein a tine is mounted on the spindle in spaced parallel relation thereto for receiving an end of the sheet to be wound on the spindle.
Claim 12
Dependent Claim
28 words
A device according to claim 5, wherein the bearing members are U-shaped having legs pierced to slidingly receive the posts and bight portions for rotatably receiving the spindle.
Claim 13
Dependent Claim
52 words
A device according to claim 1, wherein the base has a flat top and perpendicularly disposed side and end walls which in conjunction with the top define a shallow receptable, and said legs, bearing members, springs, spindle and crank are designed to be stored within the receptacle provided for by the base.
Claim 14
Dependent Claim
29 words
A device according to claim 11, wherein there are inwardly directed flanges at the lower ends of the end walls parallel to the top and resilient pads attached thereto.
