Abstract

Abstract An attachment is provided for a fork lift, or other type of industrial lift truck, for loading cotton from an elongated cotton rick into a trailer, or the like, for transportation to a cotton gin. The attachment comprises a rear wall formed of a rectangular frame covered with wire mesh, a pair of side walls hinged to the rear wall, and each formed of a rectangular frame covered with wire mesh. A series of forks are attached to the front edge of each of the side walls and extend perpendicularly to the planes of the side walls, to form a forward wall for the assembly. A further series of forks are pivotally attached to the bottom edge of each of the side walls, and these latter forks may be turned to a position in which they extend horizontally to form a bottom for the assembly. The attachment is mounted on the lift truck, and when it is lowered to ground level, the sides may be opened and the rear wall of the attachment moved adjacent the end of a cotton rick. The sides may then be closed so that the forks forming the forward wall may be moved inwardly to intermesh with one another so as to remove the cotton load from the rick, the load being squeezed together by the sides. The attachment may then be raised and suspended over a trailer. The sides may then be opened slightly, and the bottom forks turned downwardly so as to permit the load to be dumped into the trailer.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 192 words
A loading attachment for an industrial lift truck, or the like, comprising: a rear wall; a pair of side walls hinged to the side edges of the rear wall to be turned about respective vertical pivotal axes between an open and a closed position; a first and second series of elongated fork members mounted in essentially spaced and parallel relationship along the respective forward end edges of the side walls in essentially perpendicular relationship to the planes of the respective side walls, said fork members serving to form a front wall for the attachment when the side walls are in their closed position essentially parallel to one another and perpendicular to the rear wall; and means coupled to the side walls to move the side walls to their open position in which the side walls are turned away from one another about said vertical axes, and to move the side walls to their closed position in which the side walls are turned towards one another To cause the elongated fork members of the first and second series to separate the load, and to cause the side walls to squeeze against the load.
Claim 2
Dependent Claim 192 words
A loading attachment for an industrial lift truck, or the like, comprising: a rear wall; a pair of side walls hinged to the side edges of the rear wall to be turned about respective vertical pivotal axes between an open and a closed position; a first and second series of elongated fork members mounted in essentially spaced and parallel relationship along the respective forward end edges of the side walls in essentially perpendicular relationship to the planes of the respective side walls, said fork members serving to form a front wall for the attachment when the side walls are in their closed position essentially parallel to one another and perpendicular to the rear wall; and means coupled to the side walls to move the side walls to their open position in which the side walls are turned away from one another about said vertical axes, and to move the side walls to their closed position in which the side walls are turned towards one another To cause the elongated fork members of the first and second series to separate the load, and to cause the side walls to squeeze against the load.
Claim 3
Dependent Claim 32 words
The loading attachment defined in claim 1, in which said elongated fork members of the first and second series intermesh with one another when the side walls are in their closed position.
Claim 4
Dependent Claim 26 words
The loading attachment defined in claim 1, in which said last-named means comprises a pair of hydraulic cylinders coupled to respective ones of said side walls.
Claim 5
Dependent Claim 25 words
The loading attachment defined in claim 1, in which said rear wall and said side walls each comprise a frame covered with a mesh material.
Claim 6
Dependent Claim 32 words
The loading attachment defined in claim 1, and which includes a further series of elongated fork members mounted along a lower edge of the attachment to form a bottom for the attachment.
Claim 7
Dependent Claim 81 words
The attachment defined in claim 5, in which said further series of fork members are pivotally coupled to the lower edge of the attachment; and means coupled to the further series of fork members to move the same between a closed position in a horizontal plane essentially perpendicular to the planes of the side walls, and an open position in which the load in the attachment may be dumped when the side walls are moved slightly outwardly from their closed positions.
