Abstract
Abstract A longitudinal frame having a log-supporting surface for the reception of multiple stems of pulpwood positioned and secured thereon by a boom and grapple. A longitudinally movable butt plate at one end of the log-supporting surface engages the adjacent butt ends of the logs to index same into even lengths relative to a circular saw mounted at the other end of the logsupporting surface. The circular saw is mounted for movements in a plane, perpendicular to the log-supporting surface, at any given angle in the plane, through 180* of arc, relative to the log-supporting surface to saw the pulpwood into short common lengths and the boom and grapple is utilized to remove the cut lengths from the supporting surface.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
185 words
A pulpwood slasher comprising: a. a rigid longitudinally extended frame defining a logsupporting surface; b. a butt plate adjacent one end of said frame lying in a plane perpendicular to said log-supporting surface and engageable by one end of logs supported by said surface; c. power-operated saw means including mounting means adjacent the other end of said frame mounted for movements of said saw means in a plane perpendicular to said log-supporting surface and at any given angle in said plane through 180* of arc relative to said log-supporting surface, said mounting means including 1. a primary lever arm having one end pivotally secured to said rigid frame for movements in a plane perpendicular to the longitudinal axis of said supporting surface; 2. a secondary lever arm having one end pivotally secured to the other end of said primary arm for pivotal movements in a plane parallel to the movements of said primary arm; and 3. said power-operated saw means being mounted on the other end of said secondary arm for common movements therewith; d. power means for imparting said movements to said mounting means.
Claim 2
Dependent Claim
185 words
A pulpwood slasher comprising: a. a rigid longitudinally extended frame defining a logsupporting surface; b. a butt plate adjacent one end of said frame lying in a plane perpendicular to said log-supporting surface and engageable by one end of logs supported by said surface; c. power-operated saw means including mounting means adjacent the other end of said frame mounted for movements of said saw means in a plane perpendicular to said log-supporting surface and at any given angle in said plane through 180* of arc relative to said log-supporting surface, said mounting means including 1. a primary lever arm having one end pivotally secured to said rigid frame for movements in a plane perpendicular to the longitudinal axis of said supporting surface; 2. a secondary lever arm having one end pivotally secured to the other end of said primary arm for pivotal movements in a plane parallel to the movements of said primary arm; and 3. said power-operated saw means being mounted on the other end of said secondary arm for common movements therewith; d. power means for imparting said movements to said mounting means.
Claim 3
Dependent Claim
32 words
a secondary lever arm having one end pivotally secured to the other end of said primary arm for pivotal movements in a plane parallel to the movements of said primary arm; and
Claim 4
Dependent Claim
32 words
a secondary lever arm having one end pivotally secured to the other end of said primary arm for pivotal movements in a plane parallel to the movements of said primary arm; and
Claim 5
Dependent Claim
31 words
The structure of claim 1 in which said power means for imparting movements to said mounting means is connected to impart independent pivotal movements to said primary and secondary lever arms.
Claim 6
Dependent Claim
34 words
The structure of claim 2 in which said power-operated saw means is a circular saw mounted for rotation in a plane parallel to said plane of movement of said primary and secondary lever arms.
Claim 7
Dependent Claim
29 words
said power-operated saw means being mounted on the other end of said secondary arm for common movements therewith; d. power means for imparting said movements to said mounting means.
Claim 8
Dependent Claim
29 words
said power-operated saw means being mounted on the other end of said secondary arm for common movements therewith; d. power means for imparting said movements to said mounting means.
Claim 9
Dependent Claim
51 words
The structure of claim 2 in which said poWer means for imparting independent pivotal movements to said primary and secondary lever arms includes a first fluid-operated double-acting ram connected between said primary arm and said rigid frame and a second fluid-operated double-acting ram connected between said primary and secondary lever arms.
