On November 7, 1939, George G. Raymond received patents number 2 million 1hundred seventy eight thousand six hundred forty seven and forty eight. The patents were titled: ‘lift truck’ and ‘pallet’.
Or, in engineering speak:
“Two-faced pallets are used in connection with power-forked-tiering trucks. These power-forked-tiering trucks, we call them fork lifts today, not only transport the load but tier one load on top of the other. The bottom face of the pallet serves as a base for resting upon the load beneath.”
