| 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. |
