Default COVERS, Metal, No. C1 ZA/CAN 4211

Weighing in at 110 pounds, the Carriers No. 4 is the heaviest piece in the 52-Set wireless. It consists of two main parts, joined together at the sides by means of three rubber Bridge units, each side.

The lower portion of the Carriers No. 4 consists of heavy steel stock, formed and welded together to create essentially a long, U-shaped cradle mount, which is secured to a wireless table by means of two large steel clamp and bolt sets, each side.

The upper section of the Carriers No. 4 is essentially a long steel box with two inner partitions that holds the Receiver, Supply Unit and Sender components of the 52-Set. The basic box is made of one large folded, heavy gauge piece of sheet steel making up the top, rear and bottom of the wireless case. Two separate pieces, mirror images form the ends and two inner pieces form the partitions, each side of the Supply Unit. All four of these pieces, and the two end pieces of the Remote Receiver case, start out the same, but have slightly different stampings and/or holes drilled in them.

On the upper rear portion of the Carriers No. 4, a long, rectangular opening has been punched, with eight equally spaces holes top and bottom, to mount the PLUG, Assemblies, Multi and its corresponding COVERS, Metal No. C1. It is this Plug Assemblies that provides all the interconnections, but one, between the Receiver, Supply Unit and Sender.

The Cover is a single piece stamping out of the same gauge sheet steel as the case portion of the Carriers No. 4.

When removing the screws from the Cover, I was unsure of where to start. The Cover looked heavy and I wanted to be sure when down to the last screw, it stayed accessible if the Cover swung downward. Turned out to be an unnecessary concern. When the last screw was removed, the Cover stayed put. I assumed the fibre gaskets around its edge (GASKETS, Fibre, No. C1 ZA/CAN 4251) had stuck to the paint so gently started to pull backwards on the Cover. It came back about one quarter inch and still stayed put. A close look revealed a pair of retaining brackets screwed to the back of the Carriers No. 4, one at each end of the Plugs opening. Clearly, Canadian Marconi had been aware of the weight of this Cover and how difficult if could be to install it for any reason in tight quarters. Love it! A further steady pull brought the Cover completely free of the two retaining brackets, with the Plug Assemblies Multi tucked safely inside the Cover.
