Abstract: ABSTRACT OF THE DISCLOSURE A high-voltage switch is operated by a reciprocable link. The link is reciprocated by a rotatable driven member. A rotatable drive member is rotated by a switch operator. It is desired to lock the members together for conjoint rotation after each is placed in a predetermined position, for example, when the switch is closed and the operator is in the switch-closed position. The members are intended to be locked together by a fastener which passes through a hole in each member, but normal tolerances often lead to the holes being misaligned in an unpredictable manner. Accordingly, an elongated slot is formed through one member. A hole is formed through the other member. The hole is so formed as to generally overlie and encompass the slot when the members are in their predetermined positions. A disk having an off-center aperture is put in the hole and rotated until the aperture overlies and is aligned with the slot. The fastener is then inserted through the aperture and the slot to pull the disk and the members together. The members are thereby locked together for conjoint rotation.

Abstract: MODULAR SEATING ARRANGEMENT                 ABSTRACT OF THE DISCLOSURE         The specification discloses modular seating in which interchangeable arm and armless end frames include a common rear frame portion joined to each respective front frame portion in butt wise fashion to give an integrated rather than tacked on appearance.  The arm and armless end frames both have arcuately intruned rear portions and the armless has a similar arcuately intruned front portion for joining to front and rear cross supports.  In contrast, the upwardly extending front leg of the arm frame includes an inwardly projecting bracket for joining to the front cross support and a sleeve on the bracket compensates for the length of the inturned front portion of the armless frame.  Since the front and rear cross supports are at different levels, a leveling bracket or apron having tri-angular shaped sides is mounted between the front and rear cross supports to levelly support a table top thereon.

Abstract: ABSTRACT         A rolling conductor support for supporting, guid-ing, and protecting electrical, hydraulic, coolant and the like conductors extending between parts of machines which move relative to one another on guides or tracks.  The con-ductor support comprises a plurality of chains connected in parallel, laterally spaced relation by conductor supporting bridges to which the conductors are fastened by releasable securements.  The chains are comprised of a series of alter-nating and overlapping follower links and control links, overlapping portions of which are pivotally connected to each other.  Six holes are formed in each follower link, one at the center of each end for making a pivotal connection to the overlapping control link.   The remaining four holes, having stop pins secured therein, are positioned in pairs at each end of the link adjacent the pivotal connection.  Each control link is provided with one hole for pivotal connec-tion at the center of each end, and four arcuate slots are arranged in pairs adjacent each pivotal connection.   Each slot  receives  an  associated  stop pin  of  the  adjacent follower link.          The holes at the centers of overlapping ends of successive control and follower links are aligned, and a pin is inserted  therethrough  for  pivotal  connection of  the links.  As the links rotate with respect to each other, stop pins of the follower link travel within the slots of the control link.  The length of the arcuate slots of the con-trol link determines the maximum relative rotational dis-placement between successive control and follower  links. Thus, the configuration of the arcuate slots in the control link determine the minimum bending radius of the chain, and hence of the conductor support.
