Abstract

Abstract A bale rack comprises an elongate horizontal frame mounted on wheels for movement along the ground, and a pair of bale supports extending along opposite sides of the frame. The bale supports are pivotable relative to the frame between a raised position, in which the bale supports serve to retain bales on the frame, and a load release position, in which the bale supports are downwardly and laterally inclined from the frame to allow a bale to roll from the frame to the ground. Latch mechanisms are provided for releasably retaining the bale supports in the raised positions, and counterweights are provided for urging the bale supports from the lowered positions to the raised positions, thus avoiding the use of springs, hydraulic devices or other relatively complicated mechanisms for this purpose.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 322 words
A bale rack, comprising: an elongate horizontal frame; means for supporting said frame for movement along the ground; a pair of bale support means at opposite longitudinal sides of said frame for supporting first and second bales having longitudinal axes side-by-side on said bale support means, and a third bale on said first and second bales having its longitudinal axis parallel to the said longitudinal sides; means for pivotally connecting each of said bale support means to said opposite sides of said frame and permitting pivotation of said bale support means relative to said frame between a raised support position for retaining said bales on said frame and a lowered release position in which said bale support means are downwardly inclined to allow said bales to roll from said frame to the ground; latch means for releasably retaining said bale support means in the raised positions; counterweight means for urging said bale support means from the lowered positions to the raised positions; bale retaining means extending substantially vertically upwardly on said frame between said first and second bales for retaining said first and second bales on respective ones of said bale support means; bale guide means for guiding said third bale from said bale rack; pivot means for supporting said bale guide means on said bale retaining means for pivotation between an upper position, in which said bale guide means extends between said third bale and an underlying one of said first and second bales, and a lower position, in which said bale guide means are downwardly inclined towards one side of said bale rack; and stop means for supporting said bale guide means in said lower position at a height and an inclination such that said third bale can roll down said bale guide means onto a pair of bales previously deposited side-by-side on the ground after an underlying one of said first and second bales is deposited on the ground.
Claim 2
Dependent Claim 322 words
A bale rack, comprising: an elongate horizontal frame; means for supporting said frame for movement along the ground; a pair of bale support means at opposite longitudinal sides of said frame for supporting first and second bales having longitudinal axes side-by-side on said bale support means, and a third bale on said first and second bales having its longitudinal axis parallel to the said longitudinal sides; means for pivotally connecting each of said bale support means to said opposite sides of said frame and permitting pivotation of said bale support means relative to said frame between a raised support position for retaining said bales on said frame and a lowered release position in which said bale support means are downwardly inclined to allow said bales to roll from said frame to the ground; latch means for releasably retaining said bale support means in the raised positions; counterweight means for urging said bale support means from the lowered positions to the raised positions; bale retaining means extending substantially vertically upwardly on said frame between said first and second bales for retaining said first and second bales on respective ones of said bale support means; bale guide means for guiding said third bale from said bale rack; pivot means for supporting said bale guide means on said bale retaining means for pivotation between an upper position, in which said bale guide means extends between said third bale and an underlying one of said first and second bales, and a lower position, in which said bale guide means are downwardly inclined towards one side of said bale rack; and stop means for supporting said bale guide means in said lower position at a height and an inclination such that said third bale can roll down said bale guide means onto a pair of bales previously deposited side-by-side on the ground after an underlying one of said first and second bales is deposited on the ground.
Claim 3
Dependent Claim 46 words
A bale rack as claimed in claim 1, wherein said bale retaining means extend longitudinally of said bale rack and said bale guide means are mounted for pivotation relative to said bale retaining means in a direction transverse to the longitudinal direction of said bale rack.
Claim 4
Dependent Claim 86 words
A bale rack as claimed in claim 2, wherein said bale retaining means comprise a first rail extending along and above said frame, said bale guide means comprising a second rail parallel to said first rail and pivotally supported on said first rail by said pivot means, a plurality of bars each secured at one end thereof to said second rail, and counterweight means connected to said second rail for biasing said second rail towards a position of pivotation in which said bars project upwardly therefrom.
Claim 5
Dependent Claim 23 words
A bale rack as claimed in claim 1, further comprising counterweight means for uring said bale guide means towards an uppermost position thereof.
Claim 6
Dependent Claim 27 words
A bale rack as claimed in claim 1, further comprising a plurality of fingers projecting from said bale support means for engaging said first and second bales.
