Abstract: A locking system for retaining a pair of modular wall partitions in locked relationship. The locking system includes a threaded insert means in the first partition end aligned with a bolt extending through the end of the second partition. As the bolt is threaded into the insert the respective ends of the partitions are drawn together to lock the same in a rigid connection one to the other.

Abstract: A working table or desk having a grating for vertical storage of material in elongated form, such as rolled blueprints. The table has a vertically directed opening with grating forming rods extending thereacross to form spaces for inserting rolled documents for storage. A container is positioned below the opening on the floor to receive the lower ends of the material. The opening has vertical surfaces having spaced horizontally directed holes therein. Each hole on each surface is in alignment with an opposite hole in an opposite surface to receive the rods forming the grating. One of each pair of oppositely aligned holes is deeper than the other to receive a coil spring. Each rod is inserted into a deeper hole to be in abutment with the spring, the spring being compressed to permit the entry of the rod across the opening and when so compressed the other end of the rod is within the opening and in position to be forced into the opposite hole by the bias of the spring. The spring thus holds each rod in place.

Abstract: A partition formed of two spaced panels forming outer wall surfaces. The partitions are spaced by a paper honeycomb structure, passages in the honeycomb being substantially perpendicular to the panels. There are elongated H-shaped members fitted on each of two opposite ends of the panels, the H-bar of the members being adjacent the panel end edges. There is a partition stabilizing bar extending centrally between the panels and extending through a space between two sections of the honeycomb. The stabilizing bar is threaded at both ends and secured to and through the H-bars of the H-shaped members so as to prevent bowing or collapse of the partition in the direction of the bar.The method includes the steps of putting the partition together, particularly the steps of inserting the stabilizing bar between the honeycomb sections after they have been secured between the panels and of securing the stabilizing bar to the H-shaped members.
