Title: Improvements in or relating to impression cylinders for printing machines
Inventor: MESTRE LUIS
IPC: B41L19/00
Filed: 1954-08-04
Abstract: 747,004. Printing-machines. GESTETNER, Ltd. Aug. 4, 1954 [Sept. 2, 1953], No. 22677/54. Class 100 (2). Gripper mechanism for impression cylinders.- In a printing-machine impression cylinder 66, Fig. 3, of the kind having a gripper shaft 91 offset from the cylinder axis and extending lengthwise through the cylinder, one end of the shaft projecting beyond the end of the cylinder and carrying a tumbler 94 which is alternately engageable, on rotation of the cylinder with stationary pins 109, 111 carried by the machine so that the tumbler is alternately turned in opposite directions to open and close the grippers 65, the tumbler passing through a dead-centre when moving between the open and closed positions, the tumbler is connected to a link 97 shaped to clear the cylinder shaft and extending to a point substantially opposite the gripper shaft, where it is connected to spring means to hold the tumbler in each of its operative positions. The spring means consists of a pivoted lever 99 connected at one end to the link at 98 and at the other to a L-shaped member 102 to which is secured a rod 104 slidable in a block 105. A compression spring 107 surrounding rod 104 bears between block 105 and member 102. The spring tends to rotate the lever 99 in an anticlockwise direction so that the end 96 of link 97 is forced in an outward radial direction. The tumbler has a parallel sided slot 95 having flared ends 95b, 95c to receive the operating pins 109, 111. Fig. 3 shows the position as the grippers 65 move past the sheet feeding table. The pin 109 has just rotated the tumbler through the dead-centre position and is bearing on surface 95b of the tumbler controlling its closing movement. As the rotation of the impression cylinder continues the pin 109 leaves surface 95b as shown in Fig. 4, so that the grippers can close on the sheet presented to the impression cylinder. The grippers are opened after the impression cylinder has turned through about 180 degrees, by the engagement between pin 111 and surface 95c, as shown in Fig. 5. The sheet 50 is then released from grippers 65 and transferred to grippers 114 of delivery cylinder 115. Continued rotation of the impression cylinder causes the tumbler to be turned by pin 111 through the dead-centre position so that the grippers move to the fully-open position ready to receive the next sheet. Specification 747,002 is referred to.

Patent GB-824056-A (GB)
Title: A feeding mechanism, particularly for tube-stretching machines
IPC: B21C1/30
Filed: 1957-07-18
Abstract: 824,056. Rolling tubes. SINGER, F. July 18, 1957, No. 22832/57. Class 83 (4). Mechanism for feeding tubes to a metal working tool, such for example as in the machine described in Specification 686,867 for rolling tubes fed over a mandrel, in which two reciprocatory members, each of which carries a self-locking gripper, are arranged one behind the other and operate in tandem in alternate succession in such a manner that whilst one gripper grips the tube and advances it by a series of short feeding impulses, the other gripper releases the tube and returns to the starting position, is characterized in that the feeding impulses imparted by a reciprocating member carrying the tool are transmitted to the reciprocating gripper carriers by mechanical means and that the change-over in the transmission of the feeding impulses from one gripper carrier to the other is controlled by the movement of said gripper carriers themselves through the engagement or disengagement of clutches. A tube A to be stretched over a mandrel by a tool on a carrier 4 reciprocated longitudinally of the tube by crank means 2, 3, is fed in steps over the mandrel by self-locking grippers on carriers 27a, 27b reciprocated longitudinally of the tube. An extension piece 5 on the tool carrier 4 engages a cam 7 on a shaft 6 to oscillate, in conjunction with a spring 32, the shaft 6 and toothed sectors 8a, 8b secured thereto, an adjustable stop 30 engaging the sector 8a determining the stroke. The sectors 8a, 8b engage segments 12a, 12b on outer rings of one way clutches 11a, 11b, the inner rings of which are keyed to shafts 10a, 10b. The step by step rotation of the shafts 10a, 10b is transmitted by dog-tooth clutch members 13a, 13b, keyed to the shafts, to gears 21a, 21b loose on the shafts, which gears through further gearing 23a, 23b and racks 26a, 26b move the gripper carriers 27a, 27b in steps towards the tool carrier 4, the carriers being returned by motors 34a, 34b. In operation, for the gripper on the carrier 27a to feed the tube, a solenoid 19a (not shown), is energized to clutch in the gear 21a and a solenoid 19b is de-energized to move the dog-tooth clutch member 13b away from the gear 21b. The carrier 27a thus moves forward, feeding the tube. A contact arm 40a on the carrier 27a then engages a limit switch 37a, which energizes the solenoid 19b so that the carrier 27b now moves, and shortly after a limit switch 38a is engaged by the arm 40a to de-energize the solenoid 19a, so that the carrier 27b feeds alone. After a brief delay the switch 38a causes the motor 35a to move the carrier 27a back, a limit switch 39a stopping the motor. The carrier 27b is similarly operated.
