Abstract
Abstract An industrial load-carrying pallet comprising an integral sheet of material formed with strengthening ribs extending thereacross, three centrally disposed pedestals extending downwardly at the center line and generally W-shaped pedestals disposed adjacent the side extremities. Grooves extend downwardly from the upper surface and are disposed along the circumference of four circles for receiving the bottom rims of four drums. The pedestals have recesses therein disposed on the circumference of four circles whereby the pedestals may rest upon and engage the top rims of four drums. The area of the top surface within each circle for receiving the bottom rim of a drum is spherically concave. The side pedestals have spaced converging walls in a downward direction which are joined at the lower extremities by a bottom base. Empty pallets may be stacked by placing the pedestals within one another. However, there is included anti-locking means in the form of shoulders extending inwardly from the side walls of the side pedestals to engage bottom base of a like pedestal of another pallet to prevent stacked pallets from being wedged into binding engagement with one another.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
203 words
An industrial load-carrying pallet comprising; an integral sheet of material defining a top area on one face and a bottom area on the opposite face, a plurality of ribs formed in said sheet and extending downwardly thereinto from said top area, a plurality of support pedestals formed in said sheet and extending downwardly thereinto from said top area to lower extremities disposed below said ribs, a plurality of grooves formed in said sheet and extending downwardly thereinto from said top area, each of said grooves being arucate and disposed on the circumference of a groove circle for receiving the bottom rim of a drum, said pedestals having recesses extending thereinto from said lower extremities for receiving the top rim of a drum, said recesses being disposed on the circumference of a plurality of recess circles whereby each recess circle may receive the top rim of a drum, each of said groove circles being concentric to one of said recess circles, said pedestals including an elongated side pedestal along each of the opposite side extremities, each of said elongated side pedestals being generally W-shaped as viewed in plan and from the center of said pallet, some of said recesses extending across said side pedestals.
Claim 2
Dependent Claim
203 words
An industrial load-carrying pallet comprising; an integral sheet of material defining a top area on one face and a bottom area on the opposite face, a plurality of ribs formed in said sheet and extending downwardly thereinto from said top area, a plurality of support pedestals formed in said sheet and extending downwardly thereinto from said top area to lower extremities disposed below said ribs, a plurality of grooves formed in said sheet and extending downwardly thereinto from said top area, each of said grooves being arucate and disposed on the circumference of a groove circle for receiving the bottom rim of a drum, said pedestals having recesses extending thereinto from said lower extremities for receiving the top rim of a drum, said recesses being disposed on the circumference of a plurality of recess circles whereby each recess circle may receive the top rim of a drum, each of said groove circles being concentric to one of said recess circles, said pedestals including an elongated side pedestal along each of the opposite side extremities, each of said elongated side pedestals being generally W-shaped as viewed in plan and from the center of said pallet, some of said recesses extending across said side pedestals.
Claim 3
Dependent Claim
32 words
A pallet as set forth in claim 1 wherein the upper extremities of said top area between said ribs within each of said groove circles defined by said grooves is spherically concave.
Claim 4
Dependent Claim
58 words
A pallet as set forth in claim 1 wherein a plurality of said pedestals have spaced side walls which converge in a downward direction and are joined by a bottom base, and including anti-locking means for preventing stacked empty pallets from binding together when stacked with the pedestals of one pallet disposed in the pedestals of another pallet.
Claim 5
Dependent Claim
56 words
A pallet as set forth in claim 3 wherein said anti-locking means includes a plurality of shoulders disposed above said bottom base and extending inwardly from said side walls for engaging and supporting the bottom base of the pedestal of a like pallet thereby preventing stacked pallets from coming into full wedging engagement with one another.
Claim 6
Dependent Claim
