Abstract
Abstract A tree processing apparatus and more particularly an apparatus for delimbing at least two, and preferably about ten, trees simultaneously. The trees, which have been previously felled, are each loaded, by one end in the apparatus and then all the trees are substantially simultaneously moved through the apparatus while being delimbed. Means can also be provided on the apparatus to saw the trees transversely into sections.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
152 words
Apparatus for delimbing felled trees, comprising in combination: a. a longitudinally elongated support member for supporting at least two trees extending substantially transversely thereto and substantially parallel to each other, b. a longitudinally elongated frame extending over the support member, and c. two parallel moving and delimbing means horizontally spaced apart from each other and rotatably mounted about a longitudinal axis on the frame, for moving the trees substantially simultaneously transversely between the support member and the frame and substantially simultaneously delimbing the same as they are moved between said support member and said frame, each of a said moving and delimbing means comprising a plurality of mover and delimber stations, each station having one set of longitudinally extending, circumferentially spaced apart blades interleaved with a second set of longitudinally extending circumferentially spaced apart blades, the blades of each set sloping down to a point toward the blades in the other set.
Claim 2
Dependent Claim
152 words
Apparatus for delimbing felled trees, comprising in combination: a. a longitudinally elongated support member for supporting at least two trees extending substantially transversely thereto and substantially parallel to each other, b. a longitudinally elongated frame extending over the support member, and c. two parallel moving and delimbing means horizontally spaced apart from each other and rotatably mounted about a longitudinal axis on the frame, for moving the trees substantially simultaneously transversely between the support member and the frame and substantially simultaneously delimbing the same as they are moved between said support member and said frame, each of a said moving and delimbing means comprising a plurality of mover and delimber stations, each station having one set of longitudinally extending, circumferentially spaced apart blades interleaved with a second set of longitudinally extending circumferentially spaced apart blades, the blades of each set sloping down to a point toward the blades in the other set.
Claim 3
Dependent Claim
32 words
Apparatus as claimed in claim 1 including substantially circular blades extending transversely of the longitudinal blades sets, each circular blade separating adjacent stations and being attached to adjacent blades in adjacent stations.
Claim 4
Dependent Claim
30 words
Apparatus as claimed in claim 2, wherein each substantially circular blade has notches in its peripheral edge for use in cutting or breaking off limbs and in moving adjacent trees.
Claim 5
Dependent Claim
72 words
Apparatus as claimed in claim 3, wherein the support member is pivotably connected near one of its ends to the frame, and actuator means are pivotably connected between the frame and the one end of the support member for pivoting the support member relative to the frame about its pivot connection to the frame, means being provided for adjusting the elevation of the pivot connection of the support member to the frame.
Claim 6
Dependent Claim
25 words
An apparatus as claimed in claim 1 wherein sawing means are mounted on the apparatus for sawing the trees, transversely of their length, into sections.
Claim 7
Dependent Claim
64 words
An apparatus as claimed in claim 5, wherein said sawing means mounted on the frame for sawing the trees transversely of their length into sections comprise a circular saw, motor means for operating the saw, means for guiding the saw and motor means longitudinally of the frame, and means for raising or lowering the saw relative to the frame, and thus to the trees.
