Abstract: 1,130,397. Printing-machines. GESTETNER Ltd. 1 March, 1967 [9 March, 1966], No. 10423/66. Heading B6C. Apparatus for applying a cleaning liquid to a blanket cylinder 14 or a damping or priming liquid to a plate cylinder oomprises a fountain roller 10 partially immersed m the liquid in a trough 1 having a filling channel 5, a roller 13 adapted to co-operate with the roller 10, and means, including a cam 7 having a flat 6, arranged to pivot the rollers 10, 13 and the trough 1 as a unit about studs 2 so that the roller 13 is moved into and out of operative engagement with the cylinder 14, means being provided to vary the period of contact between the roller 13 and cylinder 14. The cam 7 is rotated by a pawl (26), Fig. 4 (not shown) and ratchet (25), the pawl being reciprocated by means (not shown) driven from the drive of the printing machine so as to make one reciprocation for each revolution of the blanket cylinder 14. The length of stroke of the pawl (26) is controlled by an eccentric (29) acting as an adjustable stop, and hence controlling the amount of rotation of the cam 7 for each revolution of the cylinder 14. The cam 7 is normally stationary, with the flat 6 uppermost, in which position the pawl (26) lies out of engagement with the ratchet, a pin (32), Figs. 5a, 5b (not shown) on the ratchet engaging in a slot (33) in a back plate (34), a latch (35) resting on the pin. Actuation of the cam 7 is effected by axially displacing the spindle 24, by which means the pin (32) is disengaged from the slot (33), the latch (35) falls to prevent the pin from returning to the inoperative position, and the pawl (26) engages the ratchet (25) and rotates the cam 7. As one revolution of the cam is completed, the pin (32) lifts the latch (35) and returns into the inoperative position in engagement with the slot (33). The rollers 10, 13 are held in contact by blocks 15, the pressure between the rollers being adjustable by means of a screw 16 and releasable by means of a cam 17 operated by a lever 18. The roller 13 may be rotated by frictional contact with the cylinder 14 or it may be driven by a chain drive (38), Fig. 7 (not shown), in either direction of rotation. If the roller 13 is rotated in the opposite direction to the cylinder 14, the surface speed is made greater than that of the cylinder to enable excess liquid to be scavenged from the line of contact between the cylinder and the roller.

Abstract: 1,179,220. Baling presses. INTERNATIONAL HARVESTER CO. 5 March, 1968 [13 March, 1967], No. 10576/68. Heading B5F. In a baling press of the type in which the ends of a wire slung around each bale are twisted together by a rotatable hook, the hook, in its home position, extends in the direction of advance of the bales so that the intertwisted ends are dislodged from the hook solely by movement of the bales through the press. This obviates the use of the stripping finger necessary when the hook in its home position extends transversely to the direction of bale movement. In the embodiment shown in the Figure, wire 53, one end 54 of which is held by a rotary wire holder 16, is fed by arm 19 across the rear of each bale into the holder, both the leading portion 59 and the end 54 of the wire passing over a pin 48. The hook 22 is then rotated to lift the wires from the pin and intertwine them, the wires being secured at the appropriate part of the cycle so that upon stopping the hook the twisted wires may be removed from the hook by the forward movement of the bales.
