Abstract

Abstract A car loading block for holding a load of containers from movement in a railroad car includes a rectangular sleeve of a length to extend from the stacked load to the railroad car wall or other wall. A filler comprising a pair of intersecting corrugated panels extends through the sleeve and beyond at least one end thereof. The portion of the filler extending beyond the sleeve extends between the similar sized containers and holds the sleeve between the load and the wall.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 96 words
A car loading block for use in holding a load of similarly sized containers in spaced relation to a railroad car wall, the block including: a square sleeve of corrugated paperboard of a length substantially equal to the distance between the containers and the car wall, a filler including a pair of slotted panels of corrugated paperboard, the panels being slotted to intersect one another at right angles and the edges of the panels engaging diagonally opposite corners of said rectangular sleeve, at least a portion of the filler extending beyond one end of said sleeve.
Claim 2
Dependent Claim 96 words
A car loading block for use in holding a load of similarly sized containers in spaced relation to a railroad car wall, the block including: a square sleeve of corrugated paperboard of a length substantially equal to the distance between the containers and the car wall, a filler including a pair of slotted panels of corrugated paperboard, the panels being slotted to intersect one another at right angles and the edges of the panels engaging diagonally opposite corners of said rectangular sleeve, at least a portion of the filler extending beyond one end of said sleeve.
Claim 3
Dependent Claim 19 words
The block of claim 1 and in which the corrugations of said sleeve extending parallel to the axis thereof.
Claim 4
Dependent Claim 116 words
A car loading block in combination with a pair of adjoining containers of equal height having coplanar walls in spaced parallel relation to a railway car wall, the car loading block including: a square sleeve of corrugated paperboard of a length substantially equal to the distance between said coplanar walls and said railway car wall, a filler within said sleeve, said filler comprising a pair of rectangular paperboard panels slotted to intersect at right angles to one another, each panel extending diagonally of said sleeve with opposite panel edges engaging diagonally opposite corners of said sleeve, an end of one of said panels projecting beyond said sleeve and resting upon the upper surfaces of said containers.
Claim 5
Dependent Claim 116 words
A car loading block in combination with a pair of adjoining containers of equal height having coplanar walls in spaced parallel relation to a railway car wall, the car loading block including: a square sleeve of corrugated paperboard of a length substantially equal to the distance between said coplanar walls and said railway car wall, a filler within said sleeve, said filler comprising a pair of rectangular paperboard panels slotted to intersect at right angles to one another, each panel extending diagonally of said sleeve with opposite panel edges engaging diagonally opposite corners of said sleeve, an end of one of said panels projecting beyond said sleeve and resting upon the upper surfaces of said containers.
Claim 6
Dependent Claim 37 words
The combination of claim 3 and including a second pair of containers resting upon said first named pair of containers with corners of said second pair of containers resting upon the projecting ends of said one panel.
Claim 7
Dependent Claim 27 words
The structure of claim 4 and including a projecting end on the other of said filler panels extending between the adjoining corners of said pairs of containers.
Claim 8
Dependent Claim 201 words
A series of spacers for holding containers in spaced relation to a retaining wall, the containers being rectangular and of equal height, width and thickness, said containers being arranged in two rows, the containers of one row being in superimposed relation upon the containers of the other row with the adjoining walls of the containers of one row directly above the adjoining walls of the containers of the other row and with one coplanar wall of the containers of both rows lying in spaced parallel relation to said retaining wall, said spacers each comprising: a square sleeve of corrugated papergoard of a length substantially equal to the distance between said coplanar wall and said retaining wall, a fillEr in said sleeve and extending beyond one end of the same, said filler comprising a pair of rectangular panels each slotted midway between their parallel sides and interfitted together in right angular relation, said panels extending diagonally across said sleeve with said parallel edges engaging opposite corners of said sleeve, an extending portion on one of said panels overlying the top surfaces of said adjoining containers of said one row and beneath the lower surfaces of overlying containers of said the other row.
Claim 9
Dependent Claim 201 words
A series of spacers for holding containers in spaced relation to a retaining wall, the containers being rectangular and of equal height, width and thickness, said containers being arranged in two rows, the containers of one row being in superimposed relation upon the containers of the other row with the adjoining walls of the containers of one row directly above the adjoining walls of the containers of the other row and with one coplanar wall of the containers of both rows lying in spaced parallel relation to said retaining wall, said spacers each comprising: a square sleeve of corrugated papergoard of a length substantially equal to the distance between said coplanar wall and said retaining wall, a fillEr in said sleeve and extending beyond one end of the same, said filler comprising a pair of rectangular panels each slotted midway between their parallel sides and interfitted together in right angular relation, said panels extending diagonally across said sleeve with said parallel edges engaging opposite corners of said sleeve, an extending portion on one of said panels overlying the top surfaces of said adjoining containers of said one row and beneath the lower surfaces of overlying containers of said the other row.
Claim 10
Dependent Claim 25 words
