Patent for an apparatus that consists of "a series of metal bars to be inserted between what is known as the 'channel bars or teeth,' both on the upper and lower platens of a compress used for compressing cotton-bales, which bars thus inserted shall be so attached to the channel-bars that, by the force of springs, the said bars will be kept below the surface of the teeth on the platens, allowing ample space to insert the iron bands to be used in tying the bales, in the same manner as they are now universally inserted." (Lines 13-23) Includes instructions and illustrations.
