SS.{S. Smith} REAR SPRING FRONT ANCHORAGE.

Herewith we send N.Sch. 2813 shewing the
aluminium die castings enlarged to enable the gaiter to be
carried beyond the second leaf, as was recently done on the
front springs.

The successful experiment on the front springs
would be adapted to the rear. Nothing is altered except
the die castings.

We notice on the Derby drg. that though the
front springs have a short stiff end to the second plate
on the rear springs a taper similar to that on the other
plates is obtained. Does this occur in fact, and if so
what is the explanation of the difference?
