Designation: axis for locking bracket and

Setting of on her as desired, especially, gradually rotatable Wheels.

The invention relates to an axle with a locking bracket for setting and fixing of wheels mounted on it so that it can be rotated step by step, primarily for printing type wheels of stamping, printing or labeling machines, with a number of wheels next to each other the axle arranged sit, and a wheel each in its setting on the axle by corresponding Rotation is changeable, while the other wheels here against rotation in their setting position are secured.

In such a way guided on one axis and in their setting positions to each other optionally changeable wheels, special care must be taken to ensure that the wheels are in any setting one another, precisely aligned in a line or plane over their circumference in the transverse direction in each case, that is to say not different settings lying in the radial direction

can arise in the circumference of the wheels in relation to each other in applications on stamping, printing or labeling machines for example, in this case there would be an uneven print image on the circumference of the seeder seated printer types are created on the individual wheels sitting next to each other on the axle. The individual print types were therefore disadvantageous in the overall print image next to one another with different heavy footprints appear while a good print image, same reproduction strength for each only printer type required.

For printing machines with several side by side on one axis, and independent of each other optionally adjustable type wheels, it is known (US Patent 1,868,997), in a recess in the longitudinal direction of the axis for each type wheel associated coupling parts under intermediate bearings to store a compression spring opposite the bottom of the trough-like recess in the axis, so that a kind of friction clutch under the action of these compression springs from the embedded coupling parts opposite each type wheel inside whose baben hole is created towards the axis are there means3 of an additional, only pushable rod engaging an in Longitudinally protruding rib in depressions in each case between two on the wheel circumference in the same Spaced protruding printing types, secured against rotation. Only one printing type wheel The only exception is which one in its attitude to the locking rib of this additional push rod just an interruption or recess in this rib is opposite, so that the corresponding preceding paragraph of the printing type scope is bridged like a fork, and then change this individual type wheel the separate axis of rotation with embedded coupling part under spring pressure effect accordingly

can be turned at the same time to optionally set a different print type,

It is also known for such printing machines with optionally variable type adjustment (US Patent 1,131 »959) to use an adjustment axis which can be rotated and moved lengthways is stored, and on the one hand with onχ their scope Provide a locking rib lying in the longitudinal axis direction to lock the type wheels against twisting is, while additionally on this securing rib on the opposite circumferential side of the axis, rounded, arched recesses corresponding to the number of printing type wheels used, one after the other are provided in which / under spring pressure EugelK are stored in the frame part of the printing machine, clicks into place depending on how the axis is inserted and the respectively assigned type wheel by means of Sinstellstiftes seated on the axle, engaging in Recesses radially inside the hub, then rotated with the following rotation of the axis, optionally one other printer types can be set. Both previously described versions with under spring jerk stored coupling or Grid parts have the common disadvantage that they are loosely embedded and under the action of spring force Partly difficult to assemble the machine to store, respectively. on the other hand, thrown out during dismantling for repair or other purposes and can easily be lost. But it is also known to avoid these disadvantages under pressure spring force, the locking of Pressure type wheels serving balls, or also correspondingly rounded bolt parts in radial, inside to insert blind holes lying on the axis, which holes then caulked a little on the outside so that the stored locking or adjustment are used Parts are then fixed, but still out of the TJmfane

of the axis under the action of the compression springs used still protrude so far that the locking of the type wheels engaging these protruding rounded bolt parts or balls is made possible. This also results in disadvantages in assembly, as it is hardly possible to caulk the blind holes evenly on the outside, so that accordingly, the protruding locking parts will also protrude for different lengths the internal spring pressure from the axis will also act with different forces on the individual Type wheels within whose hub bores affect what inevitably / an imprint in not straight Line with type characters slightly offset from one another, as well as with different impression thicknesses of the guys lying side by side will lead.

The subject of the registration is identified for this in that the locking axis is a partially hollow housing part with continuous in the longitudinal axis direction externally exposed.

In Figure 1, the axis according to the invention is denoted by 2, which is designed as a partially hollow housing part by a trough-like recess 6. Perpendicular to the center line of the axis 2, holes 7 through outwards are provided in the bottom of the recess 6, with towards the end the paragraph 7 ¹ of smaller diameter, as can also be seen in the plan view of the axis from above according to Fig also on smaller diameter offset ends 3 'reach outward solely from the surface of the axis 2 in order to be distributed in radially lying recesses / within the hub bores at regular intervals over the circumference, to set the corresponding type characters lying on the outer circumference of the printing wheels 1 ", optionally to be brought into engagement. In the same way, switching gears for other purposes They can be moved or fixed with step-by-step adjustment or locking options. In Fig. 1, compression springs 4 are placed on the bolt parts ^ each within the axes 7, while a bar-like insert that can be inserted into the recess 6 of the axis 2 from the outside Latch part 5 »all bolt parts 3 including applied compression springs 4- at the same time so that their smaller diameter offset ends 3 ^{1 held} within the bores 7 at a distance from their paragraphs 7 * under bias, with nj ^ en, outwardly protruding rounded ends
