ABSTRACT:
Two drive assemblies disposed one above the other and each including a telescopic spindle, a universal joint and a coupling member are released from and connected to similarly disposed driven shafts respectively by an apparatus comprising a frame slidable toward or away from the driven shafts in parallel to the extensions of the axes of the driven shafts and upper and lower holding means vertically slidably supported by posts on the front end of the frame and each adapted to hold the opposite sides of the coupling member to support the coupling member in its horizontal position in alignment with the corresponding driven shaft when the coupling is to be released from or connected to the driven shaft. For the replacement of the driven shafts, the upper and lower coupling members as supported in their horizontal position by the holding means are vertically moved in a given ratio relative to each other and thereby brought into alignment with new driven shafts. The posts supporting the holding means and the frame supporting the holding means withstand the reaction resulting from the holding of the coupling members by the holding means.
