Abstract
Means for displacing elements, such as the rollers of printing machines, located between the upright frames of a pedestal machine. A rotatable drive shaft is supported in each of the frames parallel to the direction in which the displacement is to proceed, and is drive connected to the said elements. Adjusting shafts having hand wheels attached to their free ends and coupled to the drive shafts extend, when in working position, into the space between the upright frames. In rest position, they are displaceable out of said space, which is thereby cleared for access to the equipment.
Claims8
Means for the adjustment, in a direction substantially perpendicular to its longitudinal axis, of a working element displaceably arranged between the two frames of a pedestal machine spaced from one another by a distance greater than the reach of a human's hands, comprising
- (a) two rotatable drive shafts that are each mounted on one of said frames parallel to the displacement direction, and operatively coupled to the respective longitudinal ends of said working element within the area of said frames;
- (b) two adjusting shafts each having a free end extending into the space between said frames but outside the area of adjustment of said working element, and each coupled by means of angle drives with one of said drive shafts, said adjusting shafts being movable from their working position in which they extend toward one another in substantially the same vertical plane into the space between said frames to a rest position in which they are substantially clear of said space;
- and
- (c) a hand-wheel attached to said free ends of each of said adjusting shafts;
- (d) whereby simultaneous adjustment of said working element for both sides of said frame can be made by a single operator during operation of said machine, while access to the space is made available when the machine is at rest.
