Abstract

A portable log splitting machine is disclosed wherein the splitter can be readily broken down into separate lightweight components for convenient transport and storage, such as in the trunk of an automobile. The splitter includes a ram section comprising an elongated beam with a wedge fitted at one end and a slidably-mounted pusher plate or ram which is hydraulically operated to drive a log against the wedge to split the same. The ram is reciprocably moved by the piston rod of a double-acting hydraulic cylinder. The rod is detachably connected to the ram by a simple yoke and cross pin arrangement and the cylinder is detachably fitted onto the beam by a trunnion pin that extends from the cylinder and slips into brackets carried by the beam for ready assembly and disassembly. An engine-driven pump assembly is connected to the cylinder by two detachable hoses and provides the hydraulic pressure for the cylinder.

Dependent claims

Hydraulic log splitter comprising a plurality of interconnectable subassemblies including:

a. an engine-pump unit having an engine drivingly connected to a pump and connected in fluid communication to a hydraulic reservoir;
b. a hydraulic cylinder including a double-acting piston, removably connectable to said pump section by a plurality of flexible hoses, and a piston rod reciprocably movable in response to hydraulic actuation of said piston;
c. a ram unit comprising an elongated beam having a splitting wedge disposed at one end thereof and a pusher plate slidably fitted onto said beam and removably connectable to said piston rod whereby said pusher plate is adapted to drive a log against said splitting wedge:
d. coupling means for quickly connecting and disconnecting said piston rod to said pusher plate;
and,
e. means for removably mounting one end of said cylinder onto the second end of said beam such that only outer end portions of the cylinder and beam are coextensive whereby the remaining free length of the cylinder is not substantially less than its overall length and the remaining free length of the beam is not substantially less than its overall length.
