Wireless Set No. 52 Canadian - Project

[David Dunlop]

The last small project directly related to the Vibratory Supply was finished this morning, which involved reinstalling the hardware set that had fallen out of the right side of Panels, Phenolic No. C1 (ZA/CAN 4229). This discovery was also covered back in Posts #756 and #766.

This Panels assembly is fitted to the back end of the tray in the Supply Unit the Vibratory Supply and its Case slide in and out on. The Panels supports the three Sockets, Metal, ¼-in OD 40 tpi thread, No. C1 (ZA/CAN 4583), which are basically a form of Banana Socket the Vibratory Supply plugs into when in place.

The front collars of these Sockets have ridges in them parallel to the longitudinal axis of the sockets and the sockets are fully threaded on the outside. On the backside of the Panels, Phenolic there is a 1/16-in free space between the Panels and a pair of hex nuts run up against each other and lacquered in place. This gap allows the Sockets to ‘float’ on the Panels, which allows the plugs on the back of the Vibratory Supply a better chance to capture the sockets. Probably a gauge was used on the assembly line t make it easy and consistent to attain this gap. The Sockets and Panels assemblies were likely assembled to the tray for the Vibratory Supply, before the tray was riveted in place at the bottom of the Supply Unit chassis. This latter point makes it trick to replace the right side screw assembly that had fallen out of the Panels.

When the wiring was disconnected from the Sockets, the lowermost lock washer was covered in rust that needed to be tidied up. Removing the wiring, with its large tags provided more access to where the hardware went, in behind the chassis side frame. The other thing that was necessary was to slide a wooden wedge between the chassis side frame and the back of the Panels to hold the Panels firmly up against the back end of the tray assembly. This allowed the screw to be reinstalled to fully pass through the Panels far enough to easily engage its lock washer and hex nut when the time came to fit them.
