Abstract
Abstract Apparatus for lifting logs from ground level to a bed of a log splitting machine including at least two arms forming a loading rack for the logs and a pivotally mounted lifting arm assembly which is selectively engaged and operated by rearward motion of a slideably mounted sled which is a part of the log splitting machine. The loading rack may be actuated by lifting a catch pin into contact with a pin on the sled of the splitting machine or it may be disengaged at operator's selection.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
184 words
Apparatus for attachment to and operation with a power-operated log splitter having a bed for longitudinal placement of a log between a splitting wedge and a sled reciprocally movable along said bed by a hydraulic cylinder in forward and return strokes, said apparatus comprising: (a) a loading rack pivotally connected to one side of said log splitter for rotation about an axis adjacent said bed and parallel to the direction of movement of said sled between a first position, wherein a portion of said rack is substantially at ground level to receive a log, and a second position, wherein said portion is elevated above said bed to deposit the log thereon; (b) a pin fixedly connected to said sled and extending outwardly therefrom on said one side of said log splitter; and (c) motion transmission means having a first part selectively engageable with said pin and movable with said sled when so engaged, and a second part contacting said loading rack to effect rotation thereof from said first position to said second position in response to movement of said sled upon said return stroke.
Claim 2
Dependent Claim
184 words
Apparatus for attachment to and operation with a power-operated log splitter having a bed for longitudinal placement of a log between a splitting wedge and a sled reciprocally movable along said bed by a hydraulic cylinder in forward and return strokes, said apparatus comprising: (a) a loading rack pivotally connected to one side of said log splitter for rotation about an axis adjacent said bed and parallel to the direction of movement of said sled between a first position, wherein a portion of said rack is substantially at ground level to receive a log, and a second position, wherein said portion is elevated above said bed to deposit the log thereon; (b) a pin fixedly connected to said sled and extending outwardly therefrom on said one side of said log splitter; and (c) motion transmission means having a first part selectively engageable with said pin and movable with said sled when so engaged, and a second part contacting said loading rack to effect rotation thereof from said first position to said second position in response to movement of said sled upon said return stroke.
Claim 3
Dependent Claim
42 words
The invention according to claim 1 wherein said motion transmission means is pivotally connected to said log splitter at a point between said first and second parts, for reciprocal rotation about an axis perpendicular to the direction of movement of said sled.
Claim 4
Dependent Claim
40 words
The invention according to claim 2 wherein said first part of said motion transmission means comprises elements slideably movable with respect to one another as said means is rotated and to provide said selective engagement and disengagement with said pin.
Claim 5
Dependent Claim
41 words
The invention according to claim 3 wherein said second part of said motion transmission means comprises a roller member which travels along an engagement portion of said loading rack during rotational movement of said motion transmission means and said loading rack.
