Abstract

817,930. Sampling granular &c. materials. CENTRAL ELECTRICITY GENERATING BOARD, BEARD, R. J., and LEES, B. July 23, 1956 [July 21, 1955], No. 21135/55. Class 58. [Also in Group XXX] Samples of material are delivered at regular intervals from a conveyer belt a into a receiving shoot u by reciprocation of an arm c pivoted at e and carrying a flap i hinged to the arm at h, the flap i and arm c carrying angle members k which abut to hold the flap in line with the arm on the operative stroke while the flap pivots so as to trail over the material b on the return stroke, the operative stroke being effected by a spring or weight while the return stroke is effected by motor-driven cam mechanism. The cam mechanism comprises a cam o driven at slow speed by a motor which is switched on at predetermined intervals by a timer and which is switched off at the end of one complete revolution of the cam. The cam o engages a follower n on a lever pivoted on the axis e and connected adjustably by a link m to the arm c. A spring-loaded plunger q operating in a cylinder r pivoted to a support s is connected by a rod t to the lever l. When the motor is switched on the cam moves the lever l to effect the return stroke of the arm c which compresses the spring and then releases the lever l so that the spring effects the operative stroke of arm c. The resultant downward movement of lever l is arranged to switch off the motor.
