Abstract

624,017. Pug mills. HAWK, E. A. Nov. 4, 1946, No. 32706. [Class 86] [Also in Group XXXV] A pug mill is adapted to give a constant output by driving the main shaft at a speed varying with the output flow of ceramic material. The pug mill 10 is provided with an opening 25 at the top with an elbow joint leading to a discharge aperture 32. A propeller 42 in line with the discharge aperture is rotated by the flowing ceramic material and rotates a disc 44 carrying on one side three concentric metallic rings, the two outer ones being connected through switches to opposite terminals of a reversible motor 68. The inner ring is connected through a relay switch into the generator circuit of the main motor 60. The opposite side of the disc is provided with four metal plates one of which is connected to the middle ring and another connected to the outer ring. The other plates are both connected to the inner ring. A constant speed motor 53 is provided beyond the disc 44 carrying a contact finger 56 connected through a generator 75 to the neutral terminal of the motor 68. The motor 68 operates a sliding rod 63 to actuate a Reeves gear for increasing or decreasing the speed of rotation of the pug mill shaft. If the output speed of ceramic material falls below a certain predetermined value the disc 44 slows down and the finger 56 contacts the middle ring and operates the motor 68 in a clockwise direction and so speeds up the drive on the main shaft of the pug mill. If the output becomes too great the drive is slowed down. If the plates connected with the inner ring of the disc 44 contact the finger 56 the relay switch is operated and the main drive is stopped. In an embodiment, the contact finger is rotated by means of reduction gearing and a flexible drive from a constant speed motor on a jiggering machine.
