Manufactured by Farrel Foundry & Machine Co. - Ansonia, New Haven County CT
Assigned to Farrel Foundry & Machine Co. - Ansonia, New Haven County CT

Abstract: My invention is applicable to two-roller mills, and has for its object to provide simple, strong, and durable means for raising the upper roller in use. It will be understood by those familiar with this class of machinery that owing to the enormous weight of the rollers there is great wear upon the lower journal-boxes of the upper roller and a constant tendency of the upper roller to settle o down upon the lower roller, so that the weight of the upper roller, instead of resting wholly upon its journal-boxes, rests partially and sometimes entirely upon the lower roller. Claim: In a cane-mill, the combination, with the lower roll, of the upper roll operating by its weight to crush material against the former, a supporting-frame having stationary bearings for the lower roll, horizontal recesses 14, and vertical recesses open at the top, movable bearings 8, engaging the edges of the latter recesses, cap-plates 9, wedges 12, situated in the recesses 14, screws 17 engaging said recesses and having collars 19, removable plates 13, situated between said collars, and means for securing said plates to the frame.

Manufactured by Excelsior Foundry Co. - Belleville, St. Clair County IL

Abstract: My invention relates to a cane mill and more particularly to the means for, securing the crushing rolls of the mill to their shafts. Heretofore considerable difficulty has been experienced in properly securing the crushing rolls of cane mills to their shafts. Keying the rolls to the shafts has proven unsatisfactory owing to the liability of the keys becoming broken. To overcome this difficulty rolls have sometimes been either cast integral to the shafts or shrunk to the shafts. These methods, however, have proven not only expensive but have rendered it difficult to renew the rolls or shafts in case of breakage. I overcome these difficulties by providing hollow rolls with prismatic openings adapted to receive prismatic shafts and providing the said shafts with suitable bearing blocks to form bearings in the frame of the machine. Claim: In a cane mill, the combination with a supporting frame, of a prismatic shaft supported in said frame, a hollow crushing roll provided with a prismatic opening to receive the shaft, and a pair of bearing blocks mounted in, said frame and provided with prismatic openings to receive the shaft.
