Description:
Abstract:

The principal object of our invention has been to provide a device of this nature having an accumulator, preferably of a differential type, whereby the pressure exerted upon the pistons of the mill hearing blocks will be taken by a separate piston which is subjected to substantially constant air pressure.

Claim:

In a sugar cane mill having stationary and movable bearing blocks, the combination with the movable bearing blocks thereof, of an independent, stationarily-arranged housing cylinder for 5q each block, a movable piston in each housing cylinder cooperating with said block, and an independent hydraulic accumulator, said accumulator comprising two stationary cylinders, a piston for each of said accumulator cylinders, said accumulator pistons being coactively engaged when producing pressure, said accumulator cylinders having bores of different diameters, the smaller accumulator cylinder being connected to the housing cylinder in a closed oil system, the larger accumulator cylinder being connected in a separate, closed air system and having its piston acted upon by the pressure of the air in the air system, whereby the application of air pressure of predetermined amount on the larger cylinder will produce an application of greater pressure to the mill bearing blocks by means of the piston in the smaller cylinder, an air pipe connecting a suitable source of air supply with the air cylinder of the accumulator, a pneumatically- operated shutoff valve in said pipe, a branch pipe connected in said air pipe and having one end thereof open to the atmosphere, a pneumatically- operated air relief valve connected in said branch pipe, and emergency means connected in said air system to control the closing of said shutoff valve and the opening of said air relief valve, whereby pressure upon the piston of the housing cylinder may be instantly removed by release of pressure within said air system.
