Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
230 words
A pallet for receiving the forks of a lift truck in a given direction and for transferring the load from the pallet in a direction lateral to the given direction, said pallet comprising: a rectangular frame having a pair of parallel end members and having a pair of parallel side members joined at opposite ends thereof to said end members, said end members having spaced apertures therein to admit forks of a lift truck, a pair of elongated channels secured to said end members having internal openings aligned with said apertures for receiving said forks of said lift truck, a pair of rollers journaled centrally of the height of the end members for rotation about axes parallel to said side members for supporting the load, means enabling drive of said rollers for rotating the same to transfer the load in the lateral direction, a ratchet means associated with each of said rollers, a pawl means engageable with said ratchet means to hold said ratchet means against turning, a biasing means urging said pawl means in a direction parallel to said axes to engage said ratchet means and thereby hold said rollers against turning, and means enabling shifting of said pawl means against the urging of said biasing means and a turning thereof to an inoperative position to allow turning of said rollers by said means enabling driving of said rollers.
