Abstract
Abstract A group of bales which may comprise one layer in a stack can be handled simultaneously by means of a panel of claws, preferably carried at the end of a boom of a reaching-loader vehicle. The panel of claws includes a frame carrying a multitude of shafts each having fixed thereon a plurality of claw-shaped tines. All of the shafts can be oscillated by hydraulic motor means to swing the tines point first through a continuation of the arc along which they extend to enter into and anchor themselves in a bale such as hay or straw. The frame can then be raised with its entire layer of bales, carried about by the vehicle, set down on or to start a new stack; the shafts then being oscillated in reverse direction to withdraw the tines, so that upon moving the claw panel the bales will be left where they were placed.

Claim 1
Independent Claim
200 words
Apparatus for picking up a layer of bales by top engagement therewith including a frame structure adapted to be positioned over the layer, a plurality of horizontal shafts carried by the frame structure to be pivotable about their axes, a plurality of tines carried by the shafts, shaped generally arcuately about the shaft and movable, by turning of the shaft, along the arcuate path in which they lie, between a retracted position outside of bales which are adjacent the frame, and a seizing position lying well inside of the said bales, with a portion of the tines within the bales being sufficiently nearly horizontal to lift the bales as the frame is lifted, all tines in their seizing positions being pointed generally toward tines which in turn are pointed generally toward them so that bales on these tines, assuming solidity between them, cannot back-off pointwise from either tines, and tines intermediate oppositely pointed tines which are pointed in a direction steeply transverse to the direction of the oppositely pointed tines for more reliably retaining bales not arranged in a solid layer, and means for manipulating the frame structure to raise it through a substantial range, while keeping it substantially horizontal.
