Abstract
Abstract The log splitter includes a contilivered I-beam that connects at one end to a three point tractor hitch. An hydraulically activated pusher plate slides along the I-beam to engage one end of a log placed on the beam and drives the log through a wedge-shaped splitting member having two angles of divergent. The tractor supports and adjusts the elevation of the log splitter and provides the fluid drive therefor. A ramp secured to the I-beam assists in loading heavy logs onto the splitting surface and to support the I-beam on the ground.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
179 words
A log splitter adapted to be supported by and operated from a tractor comprising an I-beam providing a base member adapted to support a log to be split, a connector frame at one end of said base member to effect cantilevered support of said base member from a tractor, log abutment means slidably mounted on said base member adapted to engage one end of a log, a wedge-shaped member on said base in opposed relation to said abutment means and adapted to engage the opposite end of a log, drive means on said base having power transfer means connectable to a tractor power system and operatively connected to said abutment means for sliding said abutment means on said base member to thereby effect relative movement between said abutment means and said wedge-shaped member to force said wedge-shaped member through a log, and ramp means connected to the web of said I-beam and extending outwardly and downwardly therefrom to facilitate the rolling of a log onto said base member and to stabilize the base member when resting on the ground.
Claim 2
Dependent Claim
179 words
A log splitter adapted to be supported by and operated from a tractor comprising an I-beam providing a base member adapted to support a log to be split, a connector frame at one end of said base member to effect cantilevered support of said base member from a tractor, log abutment means slidably mounted on said base member adapted to engage one end of a log, a wedge-shaped member on said base in opposed relation to said abutment means and adapted to engage the opposite end of a log, drive means on said base having power transfer means connectable to a tractor power system and operatively connected to said abutment means for sliding said abutment means on said base member to thereby effect relative movement between said abutment means and said wedge-shaped member to force said wedge-shaped member through a log, and ramp means connected to the web of said I-beam and extending outwardly and downwardly therefrom to facilitate the rolling of a log onto said base member and to stabilize the base member when resting on the ground.
Claim 3
Dependent Claim
38 words
A log splitter as defined in claim 1 wherein said abutment means comprises a plate extending vertically from and slideable along said base member and reversible fluid operated ram supported on said base and connected to said plate.
Claim 4
Dependent Claim
47 words
A log splitter as defined in claim 2, wherein said plate further includes depending skirt portions terminating in inwardly extending end portions disposed beneath the upper flange of the I-beam on opposite sides of the web thereof for guiding the plate in movement along said base member.
Claim 5
Dependent Claim
23 words
A log splitter as defined in claim 1 wherein said connector frame includes three connection areas arranged at the apex of a triangle.
Claim 6
Dependent Claim
24 words
A log splitter as defined in claim 1, wherein said ramp means comprises a pair of plates secured to opposite sides of said web.
Claim 7
Dependent Claim
41 words
A log splitter as defined in claim 1, wherein said wedge-shaped member includes first and second portions arranged to successively engage the log, said second portion having an angle of divergence greater than the angle of divergence of said first portion.
