ROGERS, BERESKIN & PARR Title: "PROCESS FOR MANUFACTURING AN IMPROVED LIFT TRUCK FORK" Inventor: Alan E. Green ABSTRACT OF THE DISCLOSURE A process is described for manufacturing an improved lift truck fork. In the improved lift truck fork, the curved portion of the fork, known as the "heel" is modified to reduce the stresses which arise in this area when the fork is loaded. The modifications include thickening of the heel during forming by approximately 5% toward the blade and approximately 2.5% toward the shank, enlarging the inside radius of the heel by machining and providing a clearance cavity in the top surface of the region where the blade meets the heel. The process for manufacturing lift truck forks comprises the steps of bending, then upset using a backing die of proper configuration to form a thickened portion of the heel which tapers into the lower portion of the blade, followed by restriking with a die suitably shaped to form an appropriate inside radius and clearance cavity in the heel, heat treatment and final machining to remove surface anomalies and give the desired configuration to the inside radius.
