Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
A device for splitting logs comprising the following combination: a. jack means comprising a jack post and jacking mechanism; and b. a platform block mounted upon said jacking mechanism and attached thereto, said platform block having one face to contact one end of a log to be split; and c. a wedge block fixedly attached to said jack post having a wedge with apex facing said platform block in which said wedge apex forms an acute angle with said jack post, said acute angle opening toward said platform block, to prevent said log from disengaging at the wedge block during splitting, such that, when said log to be split is inserted with one end thereof contacting said platform block and the other end thereof contacting said apex of said wedge block, and said jack means are actuated forcing said platform block toward said wedge block, said log is split.
Claim 2
Independent Claim
149 words
A device for splitting logs comprising the following combination: a. jack means comprising a jack post and jacking mechanism; and b. a platform block mounted upon said jacking mechanism and attached thereto, said platform block having one face to contact one end of a log to be split; and c. a wedge block fixedly attached to said jack post having a wedge with apex facing said platform block in which said wedge apex forms an acute angle with said jack post, said acute angle opening toward said platform block, to prevent said log from disengaging at the wedge block during splitting, such that, when said log to be split is inserted with one end thereof contacting said platform block and the other end thereof contacting said apex of said wedge block, and said jack means are actuated forcing said platform block toward said wedge block, said log is split.

Claim 4
Dependent Claim
182 words
A wedge for splitting wood having a cutting edge, a trapezoidal butt end having short and long bases, a top triangular face, a bottom triangular face, and four planar wedge surfaces, said top triangular face being generally parallel to said bottom triangular face and both triangular faces being perpendicular to said cutting edge and to said butt end, such that said bottom triangular face has as its base line said long base of said trapezoidal butt end and its apex at said cutting edge, and said top triangular face has as its base line said short base of said trapezoidal butt end and its apex at said cutting edge, said four planar wedge surfaces being defined as follows: a. by one side of said top triangular face and one side of said trapezoidal butt end; b. by the second side of said top triangular face and the second side of said trapezoidal butt end; c. by the cutting edge and one side of said bottom triangular face; and d. by the cutting edge and the second side of said bottom triangular surface.
