Claim 1
Independent Claim
217 words
For use with a fork-lift pallet having an elongated, horizontal wooden stringer provided with an inverted U-shaped opening affording entry of a tine of a fork-lift truck, a protective element comprising: a generally rectangular plate having an inverted U-shaped opening for substantial register with the stringer opening, said plate having such length and height as to protectively overlie the front face of the stringer to both sides of and above the stringer opening, said plate opening affording entry of the fork-lift truck tine to the stringer opening while the remainder of the plate protects the front face of the stringer from damage by the tine, said plate provided with perforations to receive fasteners for affixation of the plate to the stringer, at least two of which said perforations lie above and within the confines of the ends of the plate opening extended, in order to reinforce the narrow portion of the plate and stringer against buckling and a lip integral with the plate and extending rearwardly from the upper edge of the plate opening so as to engage and underlie that portion of the stringer opening along the upper edge of the stringer opening, wherein the length of the lip is spaced an appreciable distance from the edges of the plate opening and is substantially centered therein.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
157 words
For use with a fork lift pallet having an elongated, horizontal wooden stringer provided with at least two inverted U-shaped openings affording entry of tines of a fork-lift truck: at least two protective elements, each comprising a generally rectangular plate attachable to the front face of the stringer and each itself having an inverted U-shaped opening for substantial register with each stringer opening, said plates having such length and height to protectively overlie the front face of the stringer to both sides of and above each stringer opening, said plate openings affording entry to the stringer openings while the remainder of the plate protects the front face of the stringer from damage by the tine receive fasteners for affixation of the plates to the stringer, at least two of which said perforations lie above and within the ends of each plate opening extended, in order to reinforce the narrow portion of the plate and stringer against buckling.
Claim 4
Dependent Claim
157 words
For use with a fork lift pallet having an elongated, horizontal wooden stringer provided with at least two inverted U-shaped openings affording entry of tines of a fork-lift truck: at least two protective elements, each comprising a generally rectangular plate attachable to the front face of the stringer and each itself having an inverted U-shaped opening for substantial register with each stringer opening, said plates having such length and height to protectively overlie the front face of the stringer to both sides of and above each stringer opening, said plate openings affording entry to the stringer openings while the remainder of the plate protects the front face of the stringer from damage by the tine receive fasteners for affixation of the plates to the stringer, at least two of which said perforations lie above and within the ends of each plate opening extended, in order to reinforce the narrow portion of the plate and stringer against buckling.
Claim 5
Dependent Claim
60 words
The elements of claim 2 including lips integral with the plates and extending rearwardly from the upper edges of the plate openings so as to engage and underlie that portion of the stringer openings along the upper edges of the stringer openings, wherein the length of the lips is spaced an appreciable distance from the edges of the plate openings.
Claim 6
Dependent Claim
16 words
The elements of claim 3 in which the lips are substantially centered on the plate openings.
