Abstract
Abstract At attachment to the fork lift tines of a standard fork lift vehicle permits the vehicle to simultaneously engage and lift two adjacent, single width pallet stacks. The attachment includes a laterally elongated frame member for supportingly cooperating with the two adjacent pallets, a pair of channeled, L-shaped, tine-receiving members for receiving the fork lift tines, and a pair of attachment tines for doubling the pallet lifting capacity of the fork lift vehicle. When the frame member is secured to the fork lift tines, the attachment tines and the fork lift tines are located in a common plane and provide two adjacent pairs of pallet lifting tines.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
194 words
An attachment, for standard fork lift vehicles that include a pair of L-shaped lift members that provide forwardly extending pallet-engaging tines, each pallet-engaging tine having a distal toe portion and a root portion, and upwardly extending posts, for converting the vehicle from one that can only lift a single width pallet stack, said attachment comprising, in combination: laterally elongated frame means of a lateral width to supportingly cooperate with a pair of adjacent single width pallets; attachment means on said frame means for selective connection of said frame means to said pair of L-shaped lift members by supporting engagement of said frame means on the root portions of said pallet-engaging tines and by embracing portions of said upwardly extending posts; and said frame means including two forwardly projecting tines, each of said tines spaced laterally outward from said pallet-engaging tines and positioned so as to be located substantially in the plane of said pallet-engaging tines to which the frame means are to connect, whereby two adjacent pairs of pallet-lifting tine means are provided, said pairs of tine means permitting the vehicle to be selectively used to simultaneously lift two adjacent single width pallet stacks.
Claim 2
Dependent Claim
194 words
An attachment, for standard fork lift vehicles that include a pair of L-shaped lift members that provide forwardly extending pallet-engaging tines, each pallet-engaging tine having a distal toe portion and a root portion, and upwardly extending posts, for converting the vehicle from one that can only lift a single width pallet stack, said attachment comprising, in combination: laterally elongated frame means of a lateral width to supportingly cooperate with a pair of adjacent single width pallets; attachment means on said frame means for selective connection of said frame means to said pair of L-shaped lift members by supporting engagement of said frame means on the root portions of said pallet-engaging tines and by embracing portions of said upwardly extending posts; and said frame means including two forwardly projecting tines, each of said tines spaced laterally outward from said pallet-engaging tines and positioned so as to be located substantially in the plane of said pallet-engaging tines to which the frame means are to connect, whereby two adjacent pairs of pallet-lifting tine means are provided, said pairs of tine means permitting the vehicle to be selectively used to simultaneously lift two adjacent single width pallet stacks.
Claim 3
Dependent Claim
70 words
An attachment as in claim 1 wherein the attachment means includes a pair of generally L-shaped lift member-receiving means, each lift member-receiving means defined by a generally upright portion and a generally horizontal portion, a channel formed in the upright and horizontal portions of the L-shaped, tine-receiving means, the channel being of a width corresponding to the width of the lift members so as to receive the lift members therein.
Claim 4
Dependent Claim
22 words
An attachment as in claim 2 further including means for rigidly securing the frame means to the pair of L-shaped lift members.
Claim 5
Dependent Claim
47 words
An attachment as in claim 1 wherein the tine means are equally spaced with the distance between two adjacent tine means substantially equal to the width of a single width pallet stack so as to permit the simultaneous lifting and carrying of two adjacent single width pallets.
Claim 6
Dependent Claim
25 words
An attachment as in claim 1 wherein the frame means is of a longitudinal height to supportingly accommodate at least a pair of stacked pallets.
