In the longitudinal grooves 5 the advantage that they are easily slidably mounted with the conventional loose slide strips 7, their borrowed steel laths can cooperate that it Dcckflächencn with the outer surface of the middle part 2 so no special training of the guide rails 60 are flush. These slide rails 7 are, as from requires the device according to the invention Einsct- Fig. 7 can be seen, on the front end of the lower to be able to zen. In this respect, it cancels itself from the over-steel lane 10.

bridging device according to the German patent The compensation body 1 engages with its tenon 1223 516 clearly. The known device ends 3 and 4 in the steel laths 9 and 10. This is because only then can it be used. 65 Using suitable fasteners, e.g. Conveyor cage guide rails can cause a clamping effect with finger-like manner is formed ends are used. The milling of the compensation body 1 in the area of its upper Sen of fingers in the guide rails makes each pin end 3 with the upper steel lath 9 detachable

connected so that the compensating body 1 follows the movement of the steel lath 9. In contrast, that is lower pin end 4 slidably guided in the lower steel lath 10, so that in this area a relative movement between the compensation body 1 and the steel lath 10 can take place.

According to FIG. 2 are on the pin end 3 of the compensating body 1 pointing upwards, two intermediate pieces 8 inserted, which the space between the upper steel lath 9 and the middle part 2 of the Fill compensating body 1 seamlessly and its outer surfaces are flush with those of the steel lath.

In the event of a compression of the shaft tube, in which the upper steel lath 9 is down on the lower Steel gauge 10 moved to, the lower pin end 4 of the compensation body 1 further into the If the lower steel lath 10 is pushed in, the webs 6 come more and more into engagement with the sliding strips 7. This movement continues until the middle part 2 hits the lower steel lath 10. If this ao State - as in Fig. 5 can be seen - is reached, the middle part 2 and the slide strips 7 form a common closed top surface, which with the outer surfaces of the lower steel lath 10 and the Intermediate pieces 8 is flush.

Even before this compression is complete, the one adjacent to the upper steel lath 9 becomes Intermediate piece 8 removed and the compensating body 1 after loosening its clamp fastening with its upper pin end 3 by the width of the removed intermediate piece in the upper steel lath 9 pushed back, with the webs 6 and the sliding strips 7 again to a corresponding extent Disengaged and stuck again. Now, as the compression progresses move the upper steel lath 9 further downwards.

The process described can be repeated until the last spacer has been removed is.

If the shaft is pulled, in which the two steel laths 9 and 10 move away from each other, a further intermediate piece 8 is always clamped onto the compensating body 1 in sections.
