The late Rodney Pearce designed this method of coupling for 3mm scale. I saw them at an Exhibition and was fascinated by them. Rodney had needed to make each coupling to match the vehicle he was fitting, and I felt that at least in O gauge it must be possible to produce parts etched in brass that would produce identical couplings each time. I also wanted to try them on my 7mm layout where much shunting is carried out and the operators found the 3 link couplings tedious, especially at exhibitions.
After fitting Winterley Couplings to my stock, and after a little practice of the technique, the operators are able to carry out the shunting moves without ‘the hand of God’ over the layout. The benefit in O gauge is that the hook and 3 links of the existing couplings are still available so that some stock need not have them fitted. One example is a tank wagon with an open chassis; the coupling would be rather unsightly. In O gauge the couplings fit level with the underside of the buffer beam (as shown above) using 10BA bolts as supplied.
The etches in 4mm have been redesigned but work in a similar way. They are designed to replace the Bachmann coupling, although I am aware their design has since changed. I have fitted them to most makes of proprietary wagons, although much of the existing mounting has to be removed (except Bachmann as stated). Kit or scratch-built stock present no problem as the couplings fit to the floor with some packing. Fixing is with 10BA bolts supplied.
A jig is supplied to ensure the level and length on the fixed loop is standard. Vehicles with long buffer shanks need some adjustment to the hook; this is covered in the instructions. A little soldering is required, mainly to strengthen bends in the etches.
Other requirements to help make the couplings work well:
A good controller and smooth running locos help to achieve perfect working of these couplings. It is easier if uncoupling takes place where the operator can see the hooks drop; i.e. use a hand-held controller.
If your stock is very free running, they may couple/uncouple when you least expect it. I find a small piece of foam rubber placed between the floor and one wheel rim is sufficient to stop the problem and will not affect the pulling capabilities of locos with a long train.
I do not recommend shortening the loops too much to close the gap between vehicles. The gap allows for coupling/uncoupling on curves. In O gauge the gap is similar to 3-link, in 4mm the gap closer than the proprietary couplings.
HANDS FREE OPERATION – ANYWHERE!
