Abstract:

In Letters Patent #1,061,535, issued to me May 13, 1913, I stated that in three roller mills the crushing strain upon the can between the top roller and the feed roller is always less than that between the top roller and the discharge roller, the resultant line of force being inclined to the vertical, and showed means whereby the position of the top roller with respect to the lower rollers could be adjusted so that the resultant line of force would coincide as nearly as possible with the vertical center line of the housings roller mills is inclined to the vertical, as above mentioned, which causes the top bearings of the upper roller to cant and often to bind against the jaws of the cheek or housings so as to prevent them from sliding with the vertical movement of said roller. This is due to the preponderance of pressure on one half of each of said hearings on one side of the vertical center line of the housings over that on their halves on the opposite side of the said line. The object of the present invention is to provide a simple and effective means for applying the hydraulic pressure so as to prevent this canting of the top bearings and cause the said bearings to slide vertically with the movement of the top roller, and without binding, in the upper gap between the jaws of the housings.

Claim:

In a sugarcane mill, a housing, a top bearing adapted to move up and down between the jaws of said housing, a distance-piece secured between the said jaws, a hydraulic jack operating between the said top bearing and the said distance-piece, and means for adjustably clamping the plunger of the said jack to tile distance-piece.
