Abstract
Abstract A hand portable attachment for splitting logs readily attachable to and adapted to cooperatively operate with a powered piston on a tractor or similar equipment. The attachment includes a frame detachably engageable to the equipment, a wedge mounted on the frame adjacent one end of the path of travel of the piston and holding brackets to align and steady the cylinder which carries the piston. Logs are placed between the piston and the wedge and urged against the wedge causing them to split.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
177 words
A log splitting device adapted to be readily mounted on a machine which device together with the machine are capable of performing a log splitting operation in which the machine includes a piston-cylinder unit which is readily disengageable from the object on the machine which the piston normally causes to move comprising 1. holding means attachable to the machine for performance of the log splitting operation and thereafter removable from the machine, said holding means positioned, when attached, for holding the piston-cylinder unit after the unit''s disengagement from the object the piston normally causes to move, to assure that the piston moves in substantially the same paths as it is moved under normal loading; 2. frame means attachable to the machine for performance of the log splitting operation and thereafter removable from the machine, said frame means positioned, when attached, adjacent the disengaged piston; and 3. wedge means permanently connected to the frame means and positioned adjacent one end of the path of the piston to split a log interposed between the piston and the wedge means.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
30 words
frame means attachable to the machine for performance of the log splitting operation and thereafter removable from the machine, said frame means positioned, when attached, adjacent the disengaged piston; and
Claim 4
Dependent Claim
30 words
frame means attachable to the machine for performance of the log splitting operation and thereafter removable from the machine, said frame means positioned, when attached, adjacent the disengaged piston; and
Claim 5
Dependent Claim
16 words
The device of claim 1 in which the holding means are secured to the frame means.
Claim 6
Dependent Claim
19 words
The device of claim 1 in which the holding means includes bracket means which are engageable with said machine.
Claim 7
Dependent Claim
31 words
wedge means permanently connected to the frame means and positioned adjacent one end of the path of the piston to split a log interposed between the piston and the wedge means.
Claim 8
Dependent Claim
31 words
wedge means permanently connected to the frame means and positioned adjacent one end of the path of the piston to split a log interposed between the piston and the wedge means.
