Info needed: Trailer socket Humber one ton

[chrisgrove]

The link in the last post is most useful (though the drawings are of a 1/2 ton trailer and not a 1 ton). There are three pics (if you follow enough links and scroll down far enough) of the front of the 1 ton trailer (though an updated one compared to the one I am modelling - at least as far as the lights are concerned). None of these pics show a socket on the trailer. The cable appears to disappear into the chassis member that connects to the tow ring. But the pic also shows a clip, rather like the rifle holder clips in the cab, which holds the connector which plugs into the socket on the truck. The one I photographed a few years ago has one of those too, though fitted on the other side. I conclude there is no socket on the trailer, but the cable is permanently attached to the trailer wiring, and when under tow, the connector is unclipped from its holder and plugged into the truck socket.

My model will assume that anyway! Many thanks to all those who have posted such useful photos.

Hello all, attached is a pic of the 1 ton trailer with the female socket shown on the nearside draw bar. My trailer although a cargo body has the identical chassis.I am still uncertain if it had another use (cant think of one) it shows the threaded dummy to secure the cap (this was present on my trailer).
As can be seen the construction is quite different from the 1/2 ton although some of the components are the same.
Chris, the number plate holder and the convoy light are reasonably visible on the RH mudguard.

Yes. Nice pic Robert. But the pics on the other thread to which I referred - though a later updated version with the out riggers - do not show a cable socket like your pic. I am well aware that the trailers (well, mainly 3/4 ton) in my day had separate cables that connected to sockets on both the truck and the trailer, but I think the venerable 1 ton trailer had so many different lighting fits that all of us are probably right! Certainly a number of them had folding props at front and rear to keep the trailer horizontal when disconnected from the truck, as well as the jockey wheel at the front, but again, some of them didn't.

Chris, it certainly confusing now so I wonder what it was like then for a driver to pick up a trailer with different lighting leads! Am I correct in thinking that in some models they did have a lead with two male ends to connect the trailer socket to the towing vehicle socket.
It looks like (from my parts book) that the trailers meant to be stationery and level ,water tanker,generator etc ,all had props fore and aft. The cargo body looks like only having the jockey wheel.
thanks for your interest and help,
Robert

Hi Robert
Certainly some (this includes trailers other than 1 ton) trailers had a loose cable with connectors at both ends. I would assume that the connectors at each end were the same, but, since I was very seldom the guy who connected the things up. I really have no idea whether the connectors were male or female. As long as the trailer came with a cable that could be connected to the truck, it would not really matter whether it was captive on the trailer, or needed to be plugged in to it!

I am sure I have seen cargo trailers with support legs at the rear, but they could have been specialised ones converted back to cargo.

Most of these trailers that I had dealing with were those with 10kva diesel generators mounted on a flat platform, or cargo versions adapted to mount two Onan 3.5kva gen sets. I am sure they had rear support legs and seem to recollect there were two at the rear that swung down on release of a pin and then unscrewed foot as required. Unless I am getting confused with another trailer type.
