Abstract: 725,890. Mounting apparatus on racks. STANDARD TELEPHONES & CABLES, Ltd. June 24, 1953, No. 17474/53. Class 40 (4). [Also in Groups XXXVI and XL (c)] In an electrical component assembly a plurality of sub-assemblies are arranged around a central axis and pivoted on axes parallel to the central axis. Pillar 1, Fig. 1, carries component mounting plates 8 of insulating material pivoted at points 12, 120 on projections 7, 70 from supports 6, 60. Arrangements of such plates may be mounted one above the other on the pillar using a separate pair of supports 6, 60 for each group or using N- 1 supports for N vertical groups. If large components are to be mounted on a panel they may be mounted on the outer part of the panel and the adjacent panel can be cut away so that the panels can be closed into two parallel groups without damage to the components mounted thereon. Bolts 10 securing the panels to bars 11 may be lengthened to serve as stops. Access may be further facilitated by rotatably mounting the supports 6, 60 or the pillars themselves and in this case the movement is limited by stops to 180 degrees in order to avoid damage to the cables. Arrangements for minimizing the risk of damage to the supply cables in such an installation are described with reference to Figs. 4 and 5 (not shown). A modified supporting arrangement may comprise a drilled annulus as an alternative to carrying the plates on separate projections.
