Abstract
Abstract A log-splitter includes a ground-engagable beam with a hydraulic cylinder on the upper beam surface receiving pressure fluid from a vehicle to which the splitter is detachably connected for transportation and for selective lifting of the splitter. The connection of the splitter to the vehicle is made at the end of the beam nearer the center of gravity of the log-splitter.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
199 words
A log-splitter for removable attachment to a vehicle having a three-point hitch and a hydraulic pressure system including, an elongated beam, a hydraulic cylinder mounted on the upper face of said beam adjacent a first end thereof, a splitting head longitudinally spaced from said cylinder and mounted on the upper face of said beam adjacent a second end thereof, a track on said upper face between the cylinder and the head, an abutment engageable with and movable along said track and actuated by a piston rod extending from said cylinder, a transverse rod projecting from the sides of said beam adjacent said first end thereof and adapted to be detachably and pivotally connected to the lower two arms of the hitch, an upright fixed to said beam adjacent the first end thereof and adapted to be detachably and pivotally connected to the upper arm of the hitch, a pair of conduits detachably connected to the hydraulic system of the vehicle and communicating with the respective ends of said cylinder, and a control valve mounted on said beam intermediate the ends thereof and serving to direct fluid in said conduits selectively into and from the respective ends of said cylinder.
Claim 2
Dependent Claim
199 words
A log-splitter for removable attachment to a vehicle having a three-point hitch and a hydraulic pressure system including, an elongated beam, a hydraulic cylinder mounted on the upper face of said beam adjacent a first end thereof, a splitting head longitudinally spaced from said cylinder and mounted on the upper face of said beam adjacent a second end thereof, a track on said upper face between the cylinder and the head, an abutment engageable with and movable along said track and actuated by a piston rod extending from said cylinder, a transverse rod projecting from the sides of said beam adjacent said first end thereof and adapted to be detachably and pivotally connected to the lower two arms of the hitch, an upright fixed to said beam adjacent the first end thereof and adapted to be detachably and pivotally connected to the upper arm of the hitch, a pair of conduits detachably connected to the hydraulic system of the vehicle and communicating with the respective ends of said cylinder, and a control valve mounted on said beam intermediate the ends thereof and serving to direct fluid in said conduits selectively into and from the respective ends of said cylinder.
Claim 3
Dependent Claim
35 words
A log-splitter as defined in claim 1 wherein said hitch connections are of a type permitting said beam selectively to rest on the ground or to be raised to an elevated position above the ground.
Claim 4
Dependent Claim
24 words
A log-splitter as defined in claim 1 wherein said control valve is mounted at a position adjacent the fully retracted position of said abutment.
Claim 5
Dependent Claim
37 words
A log-splitter as defined in claim 1 including an inclined support member connected to said upright and said beam and extending from adjacent the top of said upright to a point intermediate the ends of said beam.
Claim 6
Dependent Claim
31 words
A log-splitter ad defined in claim 1 wherein the center of gravity of said log-splitter at all times is nearer said first end of said beam than said second end thereof.
