Abstract
Abstract A tool and method for permitting materials handling trucks of the type having standard forks on the front thereof to lift and handle loads of stacked boxes, sacks or other articles supported at their bottom only by flexible slipsheet pallets. The tool comprises an elongate frame having a pair of forwardly projecting, laterally spaced horizontal plates at the bottom thereof, such plates being ground to a sharply tapered edge at their leading edges. A respective handle is located adjacent each end of the elongate frame for use by a workman in manipulating the tool into a position such that the leading edges of the plates are at least partially inserted beneath an edge of a load-bearing slipsheet pallet while the slipsheet and load are at rest on the floor. The tool has a vertical rear surface for engaging the tips of a pair of standard lift truck forks so that the forks can be used to forcibly push the plates fully beneath the loaded slip sheet so as to be sandwiched between the slipsheet and the floor. At the bottom of the rear surface of the tool at locations directly to the rear of each of the respective forwardly projecting plates, a downwardly cammed surface having at least the width of the lift truck forks is provided. The cam surface permits the forks to be forcibly inserted beneath the forwardly projecting plates and thus below the slipsheet to permit the forks to operatively engage the underside of the loaded slipsheet and thereby lift the load.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
268 words
A hand-held tool for enabling a pair of lift truck forks to operatively engage and lift a load while said load is stacked on a slipsheet resting directly on a floor, said tool comprising: a. a laterally extending elongate frame; b. a pair of plates, having upper and lower major surfaces, attached to said frame at laterally spaced positions along the length of said frame and projecting forwardly from the bottom of said frame in a direction perpendicular to the length of said frame for inserting beneath said slipsheet, said major surfaces of each said projecting plate extending laterally with respect to said frame; c. a generally laterally extending leading edge on the forwardly projecting portion of each of said plates, each said leading edge being tapered forwardly and downwardly from the upper surface of said plate toward the lower surface thereof so as to form a sharp edge substantially coincident with the lower surface of said respective plate; d. a pair of laterally spaced, laterally extending cam surfaces, each of said cam surfaces being connected to the rear of a respective one of said plates and being inclined forwardly and downwardly to a level coincident with the lower surface of said plate for engagement by said lift truck forks; e. a laterally extending rear surface of said frame extending vertically upward from the rear of said plates for engagement by said lift truck forks to push said plates beneath said slipsheet; and f. means extending rearwardly from the top of said rear surface of said frame for preventing said forks from disengaging upwardly from said rear surface.
Claim 2
Dependent Claim
268 words
A hand-held tool for enabling a pair of lift truck forks to operatively engage and lift a load while said load is stacked on a slipsheet resting directly on a floor, said tool comprising: a. a laterally extending elongate frame; b. a pair of plates, having upper and lower major surfaces, attached to said frame at laterally spaced positions along the length of said frame and projecting forwardly from the bottom of said frame in a direction perpendicular to the length of said frame for inserting beneath said slipsheet, said major surfaces of each said projecting plate extending laterally with respect to said frame; c. a generally laterally extending leading edge on the forwardly projecting portion of each of said plates, each said leading edge being tapered forwardly and downwardly from the upper surface of said plate toward the lower surface thereof so as to form a sharp edge substantially coincident with the lower surface of said respective plate; d. a pair of laterally spaced, laterally extending cam surfaces, each of said cam surfaces being connected to the rear of a respective one of said plates and being inclined forwardly and downwardly to a level coincident with the lower surface of said plate for engagement by said lift truck forks; e. a laterally extending rear surface of said frame extending vertically upward from the rear of said plates for engagement by said lift truck forks to push said plates beneath said slipsheet; and f. means extending rearwardly from the top of said rear surface of said frame for preventing said forks from disengaging upwardly from said rear surface.
Claim 3
Dependent Claim
31 words
The tool of claim 1, further including a respective handle adjacent each end of said frame for grasping so as to position said frame and plates with respect to said slipsheet.
Claim 4
Dependent Claim
21 words
The tool of claim 1 wherein each of said tapered leading edges of said plates has a laterally extending arcuate shape.
Claim 5
Independent Claim
201 words
A method of engaging and lifting a load by means of a pair of lift truck forks while said load is stacked on a slipsheet resting directly on a floor, said method comprising: a. inserting a pair of laterally spaced plates beneath an edge of said slipsheet so that said plates partially underlie said load, each of said plates having a generally laterally extending leading edge tapered forwardly and downwardly from the upper surface of said plate toward the lower surface thereof so as to form a sharp edge substantially coincident with the lower surface of said respective plate and each of said plates having a laterally extending cam surface connected to the rear thereof, such cam surface being inclined forwardly and downwardly to a level coincident with the lower surface of said plate; b. bringing the tips of said lift truck forks into engagement with said cam surfaces and advancing said forks beneath said plate to positions underlying said slipsheet and load; c. while said slipsheet continues resting on said floor, withdrawing said forks partially from beneath said load and thereby withdrawing said plates from beneath said load; d. thereafter advancing said forks beneath said slipsheet and lifting said load.
Claim 6
Independent Claim
201 words
A method of engaging and lifting a load by means of a pair of lift truck forks while said load is stacked on a slipsheet resting directly on a floor, said method comprising: a. inserting a pair of laterally spaced plates beneath an edge of said slipsheet so that said plates partially underlie said load, each of said plates having a generally laterally extending leading edge tapered forwardly and downwardly from the upper surface of said plate toward the lower surface thereof so as to form a sharp edge substantially coincident with the lower surface of said respective plate and each of said plates having a laterally extending cam surface connected to the rear thereof, such cam surface being inclined forwardly and downwardly to a level coincident with the lower surface of said plate; b. bringing the tips of said lift truck forks into engagement with said cam surfaces and advancing said forks beneath said plate to positions underlying said slipsheet and load; c. while said slipsheet continues resting on said floor, withdrawing said forks partially from beneath said load and thereby withdrawing said plates from beneath said load; d. thereafter advancing said forks beneath said slipsheet and lifting said load.
