Abstract
Abstract A log splitter having a frame with a rail extending therealong, and with a log supporting bed with laterally disposed work receiving cradles arranged to move reciprocably along the rail. The frame carries the movable bed, with the bed being provided with log engaging faces at opposed ends thereof. A double-faced log splitting wedge is secured to the rail generally midway of the stroke motion of the bed, with the log splitting wedge being arranged to engage and split logs traveling within the bed. Means are provided for delivering fluid under pressure to a double-acting ram which is secured to the frame and to the movable bed, with the ram being adapted to move the bed along the reciprocatory path. A pair of split work-receiving cradles are secured to the bed and are arranged in oppositely disposed relationship laterally of the frame for receiving split log product from the splitter.

Claim 1
Independent Claim
236 words
A log splitter comprising, in combination: (a) a frame including an elongated flanged rail; (b) an elongated bed reciprocable along said rail through a range of travel and having pusher faces at its ends extending away from said rail and spaced by a distance greater than the travel of said bed on said rail, said bed including roller means carried at the ends thereof, for engaging the top of said rail to support said bed thereon, and guide means extending the full length of said bed for cooperating with the flanges of said rail to limit the motion of the bed to travel longitudinal of the rail; (c) a pair of log support cradles removably carried by the ends of said bed and extending therebetween, said cradles projecting laterally beyond said rail on opposite sides thereof; (d) a double edged splitting wedge removably secured to said rail between said pusher faces of said bed, the length of said bed between said pusher faces being no less than the sum of the longitudinal dimension of said wedge added to the length of a log to be split, and the travel of said bed being no less than the length of a log to be split; and (e) reversable power means connected to said rail and said bed and operable to apply force to said bed along a line passing longitudinally through said wedge and said pusher faces.

Claim 3
Dependent Claim
160 words
In a log splitter having: (a) frame means and an elongated rail means within said frame means; (b) a log supporting and driving bed arranged to move reciprocably along said rail, and having log engaging faces at opposed ends thereof; (c) a log splitting wedge disposed along said rail and between said log engaging faces, and having oppositely disposed blade surfaces, and with each blade surface being arranged for splitting contact with a log moving within said bed; (d) power supply means for delivering fluid under pressure, and double-acting ram means secured to said frame means and to said bed means and being operatively coupled to said power supply means for actuating said ram means so as to move said bed means along said reciprocatory path; and (e) a pair of log supporting carriers secured to said bed means and arranged for movement therewith, and being arranged in oppositely disposed relationship laterally of said rail for receiving split log product.
