The device illustrated in Fig. 1 operates a mechanism controlling the rotational speed of printing machinery. The mechanism controlling the drive is generally indicated at 15, variation in the speed being accomplished by movement of the pull rod 6. The device comprises a body 1 in which is slidably mounted a guide element 4 carrying a pin 3 which slides in a vertical slot in the body 1, a spring 8 forcing the element 4 downwards. A shaft 5 is journalled in the guide element 4 and rotates with respect to it, but relative axial movement is prevented by a shoulder on the shaft and by a ring 7 screwed to the shaft, the upper end of the shaft 5 being connected, via a universal joint, to a further shaft 14 and a control handle (not shown). The upper end of the pull rod 6 screws into a screw-threaded bore in the lower end of shaft 5. The pin 3 is received in a slot in lever 2, a second lever 12 constituting a pawl which can be engaged with a notch in lever 2. Thus, in operation, shaft 14 is turned manually, and this rotates shaft 5 which, however, cannot move axially and thus causes pull rod 6 to move upwards and determine the initial speed of the drive through mechanism 15; the sheet feeding and conveying means are then started. Once these latter are operating, the speed of the drive can be safely increased by pivoting lever 2 manually in an anticlockwise direction thus lifting the guide element 4 and pull rod 6. Lever 12 acting under spring bias (Fig. 2, not shown) locks the device in this position until the printing operation is completed, when it is automatically disengaged; pull rod 6 then moves downwards under the action of spring 8 to slow the drive.
