Claims8
An apparatus for inserting and removing from a rotary intaglio printing press an inking mechanism having a plate cylinder, an impression cylinder, and an ink trough, the apparatus being positionable so that the inserting and removing is in a direction transverse to the axis of the plate cylinder, said apparatus comprising:
- a movable carriage;
- support means carried by said carriage for supporting the inking mechanism;
- movement means operatively associated with said support means for raising said support means to insert the inking mechanism and for lowering said support means to remove the inking mechanism;
- a pair of front wheels and a pair of back wheels for supporting said carriage;
- mounting means for interconnecting said front and said back wheels and said movable carriage including:
- steering pin means including steering pins for interconnecting said front and said back wheels and said movable carriage, and
- guide rollers for guiding movement of said movable carriage with respect to the rotary intaglio printing press, the rotary intaglio printing press having guide means for cooperating with said guide rollers;
- and
- manual steering means for positioning said front and said back wheels in predetermined positions prior to movement of said movable carriage.

- mounting means for interconnecting said front and said back wheels and said movable carriage including:
- steering pin means including steering pins for interconnecting said front and said back wheels and said movable carriage,
- guide rollers for guiding movement of said movable carriage with respect to the rotary intaglio printing press, the rotary intaglio printing press having guide means for cooperating with said guide rollers,
- a first track rod interconnecting said steering pin means of said pair of front wheels,
- track pins connected to each of said back wheels,
- a second track rod interconnecting said track pins, and
- a push rod interconnecting said first and said second track rods;
- and
- manual steering means for positioning said front and said back wheels in predetermined positions prior to movement of said movable carriage,
- said push rod being movable by said manual steering means, said track pins connected to said back wheels lying on straight lines leading to a point midway between the front wheels so that they form a so-called steering trapezium together with the steering pin means interconnecting said front wheels and said movable carriage, said push rod including an elongate hole defined in one end thereof, the suspension means of one of the back wheels including a pin engageable with the hole, said suspension means of one of said back wheels including a second track pin and said second track rod including two slots selectively engageable with respective ones of the track pins, one of said track pins being arranged on a smaller radius with respect to the steering pin of said one back wheel than the other.
