Tree harvesting apparatus

Claim 2

A tree harvesting apparatus comprising: (a) a chassis; (b) wheels on both sides of the chassis forming a mobile vehicle with said chassis; (c) a tree collecting pocket movably mounted over said chassis on each side thereof, said pockets being limited to movement in a substantially horizontal plane; (d) separate lever means pivotably connected at one end thereof to each of said pockets; (e) vertical pivot means on said chassis for pivotably mounting the other end of said lever means to the chassis, thereby rendering each of said lever means and the pocket thereon rotatable about said vertical pivot means in a substantially horizontally disposed arc, each of said lever means being of sufficient length to extend the pockets mounted thereon to positions outside the profile of the tree harvesting apparatus; and (f) means for emptying the extended pocket whereby trees contained in said extended pocket will drop to the ground along the side of the tree harvesting apparatus.

Claim 3

A tree harvesting apparatus according to claim 1 wherein one end of each pocket is open so that the structure does not set restrictions on the length of trees to be collected into the pocket.

Claim 4

A tree harvesting apparatus comprising: (a) a chassis; (b) wheels on both sides of said chassis forming a mobile vehicle with said chassis; (c) a tree collecting pocket for holding harvested trees; (d) cooperating guide means respectively rigidly mounted on at least one side of said chassis and pivotably connected to said pocket to cooperatively provide a guide for permitting said pocket to extend in a substantially horizontal plane in a direction transverse to the longitudinal axis of said chassis to a position outside the profile of said apparatus and to pivot about an axis generally parallel to the axis of said chassis, said pivot axis located inward of the center of gravity of said pocket so that said pocket will have a tendency to pivot outward from the center axis of the apparatus to facilitate dumping of trees from said pocket; (e) an openable transverse side for said pocket hingeably connected thereto; (f) a working cylinder operatively connected between said pocket and said guide means, said working cylinder having a locking position for maintaining said pocket generally horizontal and for maintaining said side in closed position so that said pocket may retain the harvested trees, and said working cylinder having a dumping position for substantially simultaneously opening said side and pivoting said pocket to a dumping position; and (g) drive means connected to said chassis and to said pocket for moving said pocket in a direction transverse to the longitudinal axis of said chassis and in a substantially horizontal plane over those wheels on the same side of said chassis as said pockets, said drive means being arranged to extend the pocket to a position beyond the outer edge of the wheels for dumping.

Claim 5

A tree harvesting apparatus comprising: (a) a chassis; (b) wheels on both sides of said chassis forming a mobile vehicle with said chassis; (c) a tree collecting pocket for holding harvested trees; (d) cooperating guide means respectively rigidly mounted on at least one side of said chassis and pivotably connected to said pocket to cooperatively provide a guide for permitting said pocket to extend in a substantially horizontal plane in a direction transverse to the longitudinal axis of said chassis to a position outside the profile of said apparatus and to pivot about an axis generally parallel to the axis of said chassis, said pivot axis located inward of the center of gravity of said pocket so that said pocket will have a tendency to pivot outward from the center axis of the apparatus to facilitate dumping of trees from said pocket; (e) an openable transverse side for said pocket hingeably connected thereto; (f) a working cylinder operatively connected between said pocket and said guide means, said working cylinder having a locking position for maintaining said pocket generally horizontal and for maintaining said side in closed position so that said pocket may retain the harvested trees, and said working cylinder having a dumping position for substantially simultaneously opening said side and pivoting said pocket to a dumping position; and (g) drive means connected to said chassis and to said pocket for moving said pocket in a direction transverse to the longitudinal axis of said chassis and in a substantially horizontal plane over those wheels on the same side of said chassis as said pockets, said drive means being arranged to extend the pocket to a position beyond the outer edge of the wheels for dumping.
