Designation: Axle bearings for guided in rack rails Axles.

The anaide object concerns an axle bearing for guided within frame rails
Axle ends, primarily for axles of an Eäderbügel guided in frame frames with rotatably mounted pressure type wheels from self-coloring press-down stamping machines

In stamp machines of this type with an imprint of a set of adjacent character types of a number of freely adjustable print wheels mounted rotatably on an axis, in order to achieve a uniform imprint over the entire width it is necessary that the bath bar, which is stored within an outer frame, can rotate with the inside arranged Sruekrädessi a correct angle guidance; There must be precise vertical guidance when pressing down the stamping machine for the horizontally lying ends of the egg in the bathing bracket bcsw "in 4 * n" ines Habaeng "- set""g" wahri "i * t" t " _t dasd.t for on the Aehs

parallel to the impression plate or to the plane of the respective to be printed sheet «or object can be done.

It is known an axis with print wheels within it which can optionally be set and which can be fixed of a wheel hanger in a U-shape, and the wheel hanger through on both sides Outwardly protruding separately inserted stub axles with sliding shoes attached to the outside in To allow the guideways of the outer frame to intervene »On these stumps are at the same time also the movement lever for the self-inking device is still stored, the other still pivotally mounted on the outer frame, thus depending on the respective direction of movement of the wheel bracket, the dye pad is lifted when it is pressed down, or in the opposite direction to color the set of wheels is pressed again under the action of spring force. To achieve good Imprint quality is essential for the interaction of all parts for accurate guidance within the To place great demands on the framework in terms of precise machining of the individual parts, with correspondingly high manufacturing costs.

It is also known to run a wheel axle even in the outer frame with sliding shoes attached by extending it accordingly the inner wheel bracket protrudes on both sides, in which it is itself firmly inserted. But also for this a great hatred of precision is required for the processing of individual ropes, as well as the assembly or disassembly the printing press does not require simple and extensive labor.

Slide shoes made of a plastic in engagement with the guide tracks incorporated in the frame. In addition, frames themselves are also attached for such stamping machines Guide tube for the usual pressure bar, made uniformly known from plastic, in which then a metallic wheel bracket, in turn, is here but the inadequate resistance of the plastic disadvantageous to the frame, which is also too light to deliver clean prints. To avoid the disadvantages of a frame made of plastic were further acknowledged (LAS-I, 222, o85 and DGM-18951 ^ 6) only to manufacture the pressure tube for the guide rod "of the wheel bracket from a plastic, and this with the outer frame made of metal rigidly unite.

The object of the invention is now the production of single parts of the previously outlined printing machines, such as also especially their assembly be zw. Dismantling for repair purposes or the like, too Simplify, whereby by particularly expedient use of plastic materials of individual parts there is no need for post-processing, which is disadvantageous previously when using a corresponding metallic file was required.

You invention is characterized for this in that a pressure wheel axle with at both ends offset on lower IMfeng and in the center of the axis cut horizontally limited, half » cylindrical nozzle parts through holes in the side walls of the wheel bracket to be guided only half filling in a snug fit rotatably mounted 8ind, and on the outer wall sides of the wheel bracket arranged sliding shoes for engaging the Guide rails on both sides within the frame structure, with correspondingly the other half of the wall holes the wheel handle each filling out and 109835/0130

Semi-cylindrical extensions to the full axis are rotatably fitted.

In an expedient embodiment of the invention, the inner wheel bracket together with the outside can then be used attached sliding shoes made of a plastic, made from within the empty frame Metal.

The essence of the invention is described in the figures using an exemplary embodiment

Zn the figures is a stand from serer designated with 5, in which the so-called Bath bar 4 with U-shaped angled side wall parts 4 'is stored out laterally. In these Eadtr bracket 4,4 * an axle 1 is embedded, on which a number of printing type wheels 2 are lined up next to each other and are rotatably mounted, which can be set as required in the usual way in order to selectively composable series of sentences of individual character types to be able to adjust side by side and to be able to determine in each case, as it confesses in various forms, but not shown here in particular.

on the other hand, slide into the two guide tracks 5 * in the vertical direction of movement incorporated within the frame side parts 5 *. These sliding blocks 3 now have half-cylindrical nozzle parts 3 * protruding towards the bath bar side and are of such dimensions that the other half is ^{filled within the turning bores 4 H} in the bath bar, so that in cooperation with the corresponding semi-cylindrical / JHifflS JI I ^{1 of} the bath axis 1 within the bearing bores 4 "each addition to the full axis I ¹ /? ¹ is created« This, in a completely new way, deliberately avoids a fixed connection from the axis 1 in the wheel bracket 4,4 *. In contrast, the uniform connection is direct within the Eader bracket bores 4 " created between the pool axis 1,1 * and the sliding shoes 3s3 ', which sliding shoes then in turn engage directly in the guideways ^ "guided vertically. The pool axis 1,1 * including bracket 4,4 * is thereby guided opposite the vertical guideways 5" within the frame frame 5 iaaer absolutely right-angled, there. Wheel axle 1,1 * and sliding shoes 3 »3 'are ^{plugged together within the bores 4 M} in the side walls 4 * of the bath bracket, which means that dismantling and dismantling are considerably easier for you compared to previous versions, and the manufacturing tolerances for the individual parts are less precise must be adhered to, since both Ealbylinder-S do a eat hurry 1V5 * for the hooks storage nmr to be stored loosely in the wall bores 4 ".

Finally, the sub- ^{accounts 3 NI of} the sliding blocks 3 generally serve their downward movement by pressing the pressure rod 7 firmly connected to the HMderbügel 4, as a stop against the lower pressure plate 6, whereby the pressure wheels 2 can only reach through the usual cutout / inside the pressure plate 6, limited true to size . The bridge bar 7 is movably guided within a drill 8 inserted in the bridge part 5 of the frame frame in a known manner by means of a knob 9, with the usual tension spring still sitting on the push bar 7 to resiliently return the bath platform to its starting position after the impression has been made traced back.
