Apparatus for the stacking of objects

Claim 1

An apparatus for the stacking of objects, in which the uppermost one of the objects in the stack is always maintained at the same height, in which there is provided a vertically-arranged open-topped container provided with a frame supported by a number of posts, and in which the carrier for the stack of objects is suspended from the said frame with the aid of tension springs exterior of said carrier and positioned along at least two sides thereof and wherein the said carrier is in the form of an open-topped box, the bottom of which forms the supporting surface thereof and the upper edges of the side-walls of which lie substantially in the same plane as that of the surface of the said frame, said supporting surface of the said carrier being located at a considerable distance below the surface of the said frame when the carrier is in the unloaded condition, said distance being at least equal to the length of the tension springs in the unloaded condition, said carrier being provided at a location exterior of said carrier and proximate each end of two opposing side-walls with a vertically arranged member having a cross section of "W" form, the inner flange of said member being affixed to said side-wall, the two adjacent outer flanges each carrying at least a pair of wheels that coact with the inner sides of the posts of said container.
