Abstract
Abstract A bucking and log handling apparatus has a bucking station where log stems are cut to at least one desirable length. Positioned transversely from the bucking station are at least two axially spaced holding stations with means associated with one holding station to move the log segment axially. The holding stations provide temporary support for the log segments until they are called for downstream at which point the holding function is removed and the log segments fall into the outflow conveyor system. A reject mechanism allows any undesirable log segment to be removed from the system.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
160 words
A log handling apparatus comprising: means to feed at least two axially spaced but substantially abutting log segments in a direction generally transverse to their longitudinal axes, a first pair of axially spaced means positioned transversely from said feed means being arranged and adapted to accept and hold the transversely fed log segments, means to support said log segments as they move from said feed means to said first pair of axially spaced accepting and holding means, at least one of said axially spaced accepting and holding means having means for moving one of said log segments in the axial direction away from the other thereby extablishing a predetermined axial gap between the log segments, and said first pair of axially spaced accepting and holding means having means to release said log segments after actuation of said gap establishing means being arranged and adapted to allow the log segments to move in a direction generally transverse to their longitudinal axes.
Claim 2
Dependent Claim
160 words
A log handling apparatus comprising: means to feed at least two axially spaced but substantially abutting log segments in a direction generally transverse to their longitudinal axes, a first pair of axially spaced means positioned transversely from said feed means being arranged and adapted to accept and hold the transversely fed log segments, means to support said log segments as they move from said feed means to said first pair of axially spaced accepting and holding means, at least one of said axially spaced accepting and holding means having means for moving one of said log segments in the axial direction away from the other thereby extablishing a predetermined axial gap between the log segments, and said first pair of axially spaced accepting and holding means having means to release said log segments after actuation of said gap establishing means being arranged and adapted to allow the log segments to move in a direction generally transverse to their longitudinal axes.
Claim 3
Dependent Claim
50 words
The log handling apparatus as in claim 1 in which said first pair of axially spaced accepting and holding means are comprised of a plurality of stop arms arranged and adapted to extend upwardly from said support means so as to stop and hold the log segments from tranverse movement.
Claim 4
Dependent Claim
78 words
The log handling apparatus as in claim 1 in which said gap establishing means is comprised of a plurality of axial pivotal cradles associated with said one accepting and holding Means that extend a predetermined vertical distance above the plane of said support means and arranged and adapted to hold said log segments above the support means until said cradles pivot downwardly to a position below said support means thereby moving said log segment axially from the other.
Claim 5
Dependent Claim
38 words
The log handling apparatus as in claim 1 in which said support means are comprised of a plurality of inclined skid members extending from said feed means to said first pair of axially spaced accepting and holding means.
Claim 6
Dependent Claim
42 words
The log handling apparatus as in claim 1 in which said release means is comprised of a plurality of pivotally mounted upwardly extending stop arms arranged and adapted to be pivoted downwardly to a position below the plane of said support means.
Claim 7
Dependent Claim
91 words
The log handling apparatus as in claim 1 further comprising: a second pair of axially spaced accepting and holding means positioned tranversely from said first pair being arranged and adapted to accept and temporarily hold the log segments having the predetermined gap therebetween, means to support said log segments as they move from said first pair into said second pair, and means to release said log segments from said second pair being arranged and adapted to allow the log segements to move in a direction geneally tranvsese to their longitudinal axes.
