Abstract
Abstract A means for handling material with a lift truck is disclosed wherein palletized loads can be reached and positioned for lifting on the forks by use of a probe having a pallet engaging point. The probe is mounted on the forks and extends to a position considerably in advance of the forks where it can engage a remotely located pallet. Once engaged by the probe, the pallet can be moved to a fork engaging position merely by applying a pulling force with the lift fork. The probe is of light weight (in fact too light to support a loaded pallet) construction so that the operator can readily attach and remove it from the fork.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
284 words
An article of manufacture for use on a lift truck to apply pulling forces to pallets and similar loads thereby positioning them for further material handling activities comprising a lightweight, manually manipulable attachment defined by flanged base member having a vertical web portion, an upper horizontal flange extending forwardly from the upper edge of said vertical web and a lower horizontal flange extending rearwardly from the lower edge of said vertical web; a pair of holes in said web portion spaced apart a distance and being of a size sufficient to receive the forks of a conventional fork lift truck; a second pair of holes in the upper horizontal flange of said base member laterally spaced so as to register with said first pair of holes to receive locking pins to removably connect said base member to said forks; a pair of co-planar and parallel probe extensions secured at one end to said base member and extending therefrom in cantilever fashion forwardly of said forks, each of said probe extensions being defined by an L-shaped angle having horizontal and vertical legs, said horizontal legs being co-planar and disposed below the extreme ends of the forks of said fork lift truck, the vertical legs being spaced so as to fit between the forks of said lift truck; a sharpened projection at the outermost end of each probe extending vertically therefrom; whereby said base member upon being connected to the extreme ends of said forks and locked by said locking pins will support said probes in a substantially horizontal position extending forwardly and outwardly of said forks thereby to be in a position to engage and apply only horizontal pulling forces to pallets and similar loads.
Claim 2
Dependent Claim
284 words
An article of manufacture for use on a lift truck to apply pulling forces to pallets and similar loads thereby positioning them for further material handling activities comprising a lightweight, manually manipulable attachment defined by flanged base member having a vertical web portion, an upper horizontal flange extending forwardly from the upper edge of said vertical web and a lower horizontal flange extending rearwardly from the lower edge of said vertical web; a pair of holes in said web portion spaced apart a distance and being of a size sufficient to receive the forks of a conventional fork lift truck; a second pair of holes in the upper horizontal flange of said base member laterally spaced so as to register with said first pair of holes to receive locking pins to removably connect said base member to said forks; a pair of co-planar and parallel probe extensions secured at one end to said base member and extending therefrom in cantilever fashion forwardly of said forks, each of said probe extensions being defined by an L-shaped angle having horizontal and vertical legs, said horizontal legs being co-planar and disposed below the extreme ends of the forks of said fork lift truck, the vertical legs being spaced so as to fit between the forks of said lift truck; a sharpened projection at the outermost end of each probe extending vertically therefrom; whereby said base member upon being connected to the extreme ends of said forks and locked by said locking pins will support said probes in a substantially horizontal position extending forwardly and outwardly of said forks thereby to be in a position to engage and apply only horizontal pulling forces to pallets and similar loads.
Claim 3
Dependent Claim
56 words
An article according to claim 1 wherein said probe point is of a sharpness sufficient to penetrate wooden portions of the pallet thereby to engage in and wherein each of said extensions is sufficiently strong enough to withstand the vertical loads applied to cause such penetration but are not strong enough to support a loaded pallet.
Claim 4
Dependent Claim
16 words
An article according to claim 2 wherein each said probe point extends upwarDly from the probe.
Claim 5
Dependent Claim
16 words
An article according to claim 1 wherein each said probe point extends downwardly from the probe.
Claim 6
Dependent Claim
16 words
An article according to claim 1 wherein each said probe point extends upwardly from the probe.
