Abstract: A series of pumps for precise metering of ink to all zones of a web press. One set of the ink pumps is operated by a set of motors, one motor for every two zones. The motors are reversible, preferably with a toothed belt driving each pump. The other units include one motor for each pump, with the motor driving a shaft which drives a link arm, the link arm driving a pivot shaft with a variable stroke, ranging from zero to a full output. The link arms are driven individually or as a group, and each has its own stroke. In one case, the pivot shafts are operated by link arms which can be in or out of phase with each other. In another case, an eccentric on the drive shaft can be adjusted to produce a variable stroke of the link arms and the pivot shafts.

Abstract: An inking system for an offset printing press having a stationary portion and a movable portion that is movable toward and away from a roller. A plurality of hinge pins form a pivot axis between the stationary and movable portions. Each of the hinge pins having at least one hollow end portion communicating axially with one of the stationary and movable portions permitting ink flow. Each of the hinge pins also having a radial passage for ink, whereby the ink may pass from the stationary portion to the movable portion, and whereby the ink may be supplied to the movable portion during change of the relative positions of the stationary and movable portions.
