Abstract: 875,687. Printing machines. LINOTYPE & MACHINERY Ltd., and WARD, R. Sept. 24, 1959 [Sept. 24, 1958], No. 30511/58. Classes 100(1) and 100(2) In a sheet counting device for a printing press equipped with a chain delivery mechanism carrying a sheet gripper assembly which transports the printed sheets from the printing unit to a sheet delivery pile, the counting device cornprises a counter and electric circuitry for actuating the counter, the circuitry being energized for actuation of the counter when, but only when, a printed sheet is present in the gripper assembly transporting the sLeet from the printing unit to the delivery pile. One gripper finger 10 of each set of grippers is connected to the earth side 11 of an electrical circuit and the corresponding gripper pad 12 is connected to a brush 14 carried, together with a brush 15, by one side of the chain delivery mechanism. The brush 15 is connected to earth. Contact strips 17, 18 are secured to the side of the machine frame for engagement by the brushes 14, 15, the brush 14 engaging the strip 17 before the brush 15 engages the strip 18. The strip 17 is connected through a relay coil R.L. to one terminal 20 of an electric supply the other terminal of which (not shown) is connected to earth. The strip 18 is also connected to the terminal 20 through normally closed contacts RL1 and an electric counter 21. When the relay coil RL is energized the contacts RL1 are opened thereby. If a sheet 23 is held by the grippers the finger 10 and pad 12 are held out of contact so that when the brush 14 engages the strip 17 the relay RL is not energized. When the brush 15 subsequently engages the strip 18 the circuit to the counter 21 is completed and the latter is advanced by one unit. If there is no sheet between the grippers, however, the relay RL is energized when the brush 14 contacts the strip 17 and the contacts RL1 are opened so that the counter 21 is not advanced when the brush 15 contacts the strip 18.
