Abstract

423,637. Masticating rubber. WOODCOCK, W. J., and JOHN BULL RUBBER CO., Ltd., Evington Valley Mills, Leicester. March 17, 1934, No. 8444. [Class 70] [See also Group II] Means for maintaining a constant predetermined temperature of rubber during mastication in a roller mill comprises a metal plough 5 adapted to cut through the rubber on the roll and means associated with the plough for controlling the supply of cooling water to the mill. As shown, in a cavity in the plough 5 is a bulb 8 containing alcohol. The bulb is connected by a tube 9 to a diaphragm chamber 10 on the upper surface of which rests a lever arm 12. When the alcohol expands the lever 12 is pressed upwards and acts on another lever 20 at the end of which is a pad adapted to close more or less an opening 23 in an air pipe, thereby varying the air pressure in a pipe 31 leading to a water-controlling valve 35 in the water pipe supplying water to the interior of the rolls 3, 4 and to a spraying device 39. The air pipe 31 also leads to a valve 41 controlling the supply of air to the spraying device 39.
