Abstract
Abstract Apparatus is provided for splitting wood and specifically logs. The apparatus includes a conical splitting device which is attached to a vehicle wheel hub and is rotated as the wheel is driven. A separate mounting plate attaches the splitting device to the wheel hub which enables one splitting device to be mounted on a variety of vehicle wheel hubs by the use of a variety of mounting plates. The splitting device itself has a spirally-grooved cone with a truncated conical portion behind the cone to prevent the possibility of logs riding up the device and damaging the wheel hub or adjacent portions of the vehicle.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
149 words
A wood splitter comprising wall means forming a cone having a tip and a base edge, said cone tapering away from said base edge to said tip, said cone having at least one spiral groove extending substantially from said tip to said base edge, wall means forming a truncated conical portion having a small diameter outer edge substantially equal to the diameter of the base edge of said cone and affixed thereto and having a larger diameter inner edge, said truncated conical portion being formed with an included angle which is effective to enable said truncated conical portion to further aid in splitting the wood when coming into contact therewith, wall means forming a cylindrical base wall having a diameter substantially equal to the larger diameter of said truncated conical portion and affixed thereto, and means for connecting said cylindrical base wall to drive means for rotating said cone.
Claim 2
Dependent Claim
149 words
A wood splitter comprising wall means forming a cone having a tip and a base edge, said cone tapering away from said base edge to said tip, said cone having at least one spiral groove extending substantially from said tip to said base edge, wall means forming a truncated conical portion having a small diameter outer edge substantially equal to the diameter of the base edge of said cone and affixed thereto and having a larger diameter inner edge, said truncated conical portion being formed with an included angle which is effective to enable said truncated conical portion to further aid in splitting the wood when coming into contact therewith, wall means forming a cylindrical base wall having a diameter substantially equal to the larger diameter of said truncated conical portion and affixed thereto, and means for connecting said cylindrical base wall to drive means for rotating said cone.
Claim 3
Dependent Claim
19 words
A wood splitter according to claim 1 characterized by said truncated conical portion having an ungrooved, smooth outer surface.
Claim 4
Dependent Claim
79 words
A wood splitter according to claim 1 characterized by said connecting means comprising a plurality of bolt openings located around said cylindrical base wall near an inner edge thereof, and said connecting means further comprising a mounting plate having a plurality of bolt openings positioned to be aligned with the bolt openings of said cylindrical base wall and further having means for connecting the mounting plate to a powered wheel hub of a vehicle which constitutes the drive means.
Claim 5
Dependent Claim
34 words
A wood splitter according to claim 3 characterized by nuts in alignment with said base wall openings, and said mounting plate having bolts extending through said base wall openings and threaded into said nuts.
Claim 6
Dependent Claim
32 words
A wood splitter according to claim 3 characterized by said last-named means comprising a plurality of stud holes in said mounting plate positioned to be aligned with studs of the wheel hub.
Claim 7
Dependent Claim
40 words
A wood splitter according to claim 1 characterized by said truncated conical wall means extending into the base of said cone and having a transverse wall perpendicular to the axis of the splitter near the base edge of said cone.
Claim 8
Dependent Claim
209 words
A wood splitter assembly to enable one wood splitter to be connected and driven by various wheel hubs of automobiles, said assembly comprising wall means forming a base and wall means forming a cone tapering away from said base, said cone having a groove extending at least a substantial portion of the length thereof, wall means forming a truncated conical portion connecting said cone and said base and tapering away from said base, said truncated conical portion being formed with an included angle which is effective to enable said truncated conical portion to further aid in splitting the wood when coming into contact therewith, said base having connecting means comprising a plurality of bolt openings spaced around said base near an inner edge thereof, a mounting plate having connecting means spaced therearound and positioned to be connected with said connecting means of said base, said mounting plate having a plurality of stud holes located to be aligned with studs of a wheel hub and spaced inwardly from said plate connecting means to enable said mounting flange to be affixed to a wheel hub of at least one automobile, and said mounting plate having a large central opening therein, the periphery of which is spaced inwardly from said stud holes.
Claim 9
Dependent Claim
209 words
A wood splitter assembly to enable one wood splitter to be connected and driven by various wheel hubs of automobiles, said assembly comprising wall means forming a base and wall means forming a cone tapering away from said base, said cone having a groove extending at least a substantial portion of the length thereof, wall means forming a truncated conical portion connecting said cone and said base and tapering away from said base, said truncated conical portion being formed with an included angle which is effective to enable said truncated conical portion to further aid in splitting the wood when coming into contact therewith, said base having connecting means comprising a plurality of bolt openings spaced around said base near an inner edge thereof, a mounting plate having connecting means spaced therearound and positioned to be connected with said connecting means of said base, said mounting plate having a plurality of stud holes located to be aligned with studs of a wheel hub and spaced inwardly from said plate connecting means to enable said mounting flange to be affixed to a wheel hub of at least one automobile, and said mounting plate having a large central opening therein, the periphery of which is spaced inwardly from said stud holes.
Claim 10
Dependent Claim
53 words
A wood splitter assembly according to claim 7 characterized by said base being cylindrical, the larger end of said truncated conical portion having a diameter substantially equal to the diameter of said base, and the smaller end of said conical portion being substantially equal to the diameter of the base of said cone.
Claim 11
Dependent Claim
163 words
A wood splitter assembly to enable one wood splitter to be connected and driven by various wheel hubs of automobiles, said assembly comprising wall means forming a base and wall means forming a cone tapering away from said base, said cone having a groove extending at least a substantial portion of the length thereof, said base having a mounting flange with a plurality of bolt openings spaced around said flange near an inner edge of said base, a mounting plate having a plurality of bolts integrally affixed thereto and positioned to be aligned with the bolt holes of said mounting flange, said mounting plate having a plurality of stud holes spaced inwardly from said bolts and positioned to be aligned with studs of various wheel hubs of automobiles to enable said mounting plate to be affixed to wheel hubs of automobiles, and said mounting plate further having a large central opening therein, the periphery of which is spaced inwardly from said stud holes.
Claim 12
Dependent Claim
163 words
A wood splitter assembly to enable one wood splitter to be connected and driven by various wheel hubs of automobiles, said assembly comprising wall means forming a base and wall means forming a cone tapering away from said base, said cone having a groove extending at least a substantial portion of the length thereof, said base having a mounting flange with a plurality of bolt openings spaced around said flange near an inner edge of said base, a mounting plate having a plurality of bolts integrally affixed thereto and positioned to be aligned with the bolt holes of said mounting flange, said mounting plate having a plurality of stud holes spaced inwardly from said bolts and positioned to be aligned with studs of various wheel hubs of automobiles to enable said mounting plate to be affixed to wheel hubs of automobiles, and said mounting plate further having a large central opening therein, the periphery of which is spaced inwardly from said stud holes.
