Abstract
A log splitter having a manually adjustable wedge and a power driven base for supporting the log and forcing it upwardly into the splitting wedge. The wedge is supported by a carriage that is releasably secured to two standards by a pair of quick-release clamps, operable with one hand. The support includes a central projection extending toward and in alignment with the terminus of the wedge to minimize twisting moments generated by the splitting forces.
Claims9
In apparatus for splitting a log, the combination comprising
- a frame,
- a support slidably mounted on said frame and adapted to engage one end of a log to be split,
- a carriage slidably mounted on said frame,
- a wedge secured to said carriage and adapted to engage the opposite end of said log,
- manual quick-release clamping means slidably mounted with respect to said frame including spring means normally clamping said carriage to said frame and lever means arranged to be actuated with one hand against the force of said spring means to release said carriage from said frame, and
- drive means arranged to cause relative closing movement between said support and said wedge thereby to force said wedge into said log.

In apparatus for splitting a log, the combination comprising
- a frame,
- a carriage mounted on said frame,
- a wedge secured to said carriage and having a terminus adapted to engage one end of a log to be split,
- support means for the opposite end of said log, and
- drive means arranged to produce relative closing movement between said support means and said carriage,
- said support means having a first surface generally facing said wedge, a projection extending from said first surface in alignment with said terminus in the direction of the path of said closing movement, said projection having a second surface of a least one square inch generally facing said wedge and being spaced from said first surface and adapted to engage said opposite end of said log and prevent contact between said log and said first surface adjacent said projection thereby to minimize the generation of twisting moments.
