Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
211 words
An apparatus for felling and bundling trees, said apparatus being mounted on a vehicle and being adapted to fell trees during the time that the vehicle is in actual movement over the ground, which comprises in combination: a. a motor driven cutter device, b. means for adjusting the height of said cutter device with respect to the ground, c. an elongated collecting trough for cut trees located rearwardly and above said cutter device, d. a tree engaging means positioned above said cutter device and which comprises 1. a generally horizontally disposed member, 2. one end of said member being yieldably mounted so that it will be moved backwardly by a tree during the time that the cutter device is cutting through a tree, 3. the other end of said member having means for engaging the tree trunk and supporting it against downward movement after the tree has been severed, e. means for moving the tree engaging means forwardly with great force and high speed as soon as the cutter device has severed a tree, whereby when a tree had been severed by said cutter device said engaging means will apply sudden force against the lower end of the severed tree and cause it to topple backwardly into said elongated collecting trough.
Claim 2
Independent Claim
211 words
An apparatus for felling and bundling trees, said apparatus being mounted on a vehicle and being adapted to fell trees during the time that the vehicle is in actual movement over the ground, which comprises in combination: a. a motor driven cutter device, b. means for adjusting the height of said cutter device with respect to the ground, c. an elongated collecting trough for cut trees located rearwardly and above said cutter device, d. a tree engaging means positioned above said cutter device and which comprises 1. a generally horizontally disposed member, 2. one end of said member being yieldably mounted so that it will be moved backwardly by a tree during the time that the cutter device is cutting through a tree, 3. the other end of said member having means for engaging the tree trunk and supporting it against downward movement after the tree has been severed, e. means for moving the tree engaging means forwardly with great force and high speed as soon as the cutter device has severed a tree, whereby when a tree had been severed by said cutter device said engaging means will apply sudden force against the lower end of the severed tree and cause it to topple backwardly into said elongated collecting trough.
Claim 3
Dependent Claim
30 words
one end of said member being yieldably mounted so that it will be moved backwardly by a tree during the time that the cutter device is cutting through a tree,
Claim 4
Dependent Claim
30 words
one end of said member being yieldably mounted so that it will be moved backwardly by a tree during the time that the cutter device is cutting through a tree,
Claim 5
Dependent Claim
39 words
An apparatus according to claim 1 wherein said means for moving the tree engaging means forwardly with great force and high speed comprises a spring that is placed under compression when said member is moved backwardly by a tree.
Claim 6
Dependent Claim
31 words
An apparatus according to claim 1 wherein the cutter device is supported by parallel arms pivotally mounted to the vehicle and adapted to maintain the cutter device in any desired position.
Claim 7
Dependent Claim
87 words
the other end of said member having means for engaging the tree trunk and supporting it against downward movement after the tree has been severed, e. means for moving the tree engaging means forwardly with great force and high speed as soon as the cutter device has severed a tree, whereby when a tree had been severed by said cutter device said engaging means will apply sudden force against the lower end of the severed tree and cause it to topple backwardly into said elongated collecting trough.
Claim 8
Dependent Claim
87 words
the other end of said member having means for engaging the tree trunk and supporting it against downward movement after the tree has been severed, e. means for moving the tree engaging means forwardly with great force and high speed as soon as the cutter device has severed a tree, whereby when a tree had been severed by said cutter device said engaging means will apply sudden force against the lower end of the severed tree and cause it to topple backwardly into said elongated collecting trough.
Claim 9
Dependent Claim
37 words
An apparatus according to claim 1 wherein the end portion of the elongated collecting trough that is nearest the cutter device is provided with a forwardly open U-shaped space for accomodating the tree during the cutting operation.
Claim 10
Dependent Claim
27 words
An apparatus according to claim 1 wherein said elongated collecting trough is mounted on the vehicle so as to be tiltable laterally by means of hydraulic cylinders.
Claim 11
Dependent Claim
31 words
An apparatus according to claim 1 which includes guiding means for preventing the cut tree from falling sideways and for guiding the tree to a proper position in the collecting trough.
Claim 12
Dependent Claim
54 words
An apparatus according to claim 6 characterized in that said guiding means comprises a rotatable arcuate arm which is adapted to be actuated by means of a motor, said arm extending from its axis of rotation forwards in the direction of movement of the apparatus and in its operative position partially enclosing the tree.
Claim 13
Dependent Claim
14 words
An apparatus according to claim 1 wherein said cutter device comprises a cutting disc.
