Patent for a new and improved power device for baling presses. This design "relates to certain new and useful improvements in power devices for baling-presses of that class wherein is employed a disk rigidly fixed to the shaft of the crank and a disk loosely mounted on said shaft; and it has for its object to improve upon prior constructions of this character. [This design] hinge[s] the lugs on the loosely mounted disk, and, preferably, place a spring between the said lug and the disk, so that either the weight of the lug or the force of the spring will project or suspend the lug" (lines 13-24).
