All carriage springs, with the exception of those of carriages Nos. 205, 206, 103 and 104, are semi-elliptic solid eye back plate type. Quite a number of these springs break every month. The breakage is on the back plate just in front of the solid eye.
A number of methods of reducing this breakage has been tried. The only method that gave any success was the discarding of the solid eye back plate and the use in its place of the loose washer type of back plate. Six carriage springs to this type of back plate have been altered and after nearly a year in service, not one has broken. It has therefore been decided that when the present stock of solid eye back plate semi-elliptic springs are exhausted, they will be replaced with the loose washer back plate type of semi-elliptic springs.
