Abstract

Abstract The invention relates to a side loading fork lift device adapted to be used with fork lifts of a fork lift truck. The device comprises a pair of parallel fork lifts extending forwardly from a swing arm assembly which can rotate on a platform to the left or right. The platform comprises a pair of parallel sleeves adapted to engage the fork lifts of a truck. The device comprises several safety features such as means to secure the device to the truck, means to secure the swing are in a rotated position, leg stands on the device, and heels on the fork lifts for preventing any sliding of a load thereon.

Claim 1
Independent Claim 291 words
A side loading fork lift device adapted for use with permanently forward extending fork lifts of a fork lift truck and the like comprising: a. a pair of horizontal, parallel fork receiving members and plate means secured between and across the tops of said receiving members to form a platform; b. rigid shaft means centrally disposed vertically on said platform; c. a rotatable swing arm assembly including horizontal plate means disposed on said platform forwardly of said shaft means, and comprising hub means adapted to securely engage and to rotate at least 180* on said shaft means; d. an arcuate bearing surface disposed on the underside of said swing arm plate means adapted to contact the surface of said plateform and move thereon in an arcuate path; e. a pair of parallel fork means mounted on and disposed forwardly of said rotatable swing arm assembly; f. chain and hook means secured to the rear of said platform and detachably securable to said truck, whereby said device is retained on said fork lifts of said truck; g. said fork receiving members including means adapted to detachably secure spacer means within said receiving members, whereby forks of a truck narrower than said receiving members can be received and snugly retained; h. a circular series of holes in said platform each adapted to match with a hole in said swing arm plate means, retaining pin means on said swing arm assembly adapted to be placed through matched hole means and thereby retain said swing arm assembly in a desired position on said platform; i. heel means disposed within the extremities of said parallel fork receiving members to assist in retaining loads therein; j. leg stands disposed on the undersides of said fork receiving members.
