THE COLLIERY GUARDIAN.

1107

The Danger of Overwinding

owing to the brakes failing to act at the critical
moment, may be obviated by having your brakes
fitted with Ferodo linings. Possessing a very
high co-efficient of friction, Ferodo fabrics will
pull up your engines in less time and with
greater certainty than wood blocks or metal
brakes. They permit of faster winding without
the slightest danger.
