To	Colliery Proprietors,

IMPORTANT	Engineers and

.....	Contractors, &c.

To secure dependable winding and absolute
safety,	all	gear	brakes	should	be fitted with

Cresswells* “CHEKKO” Semi-metallic Asbestos
Brake or Clutch Linings.

Their grip is firm as a rock, yet responsive
and pliant as a hand grasp. “ CHEKKO ’* provides
instant and perfect retardation at all speeds and
under all loads. “CHEKKO” is a great precaution
against overwinding.

We make no brakes of cotton fabrics or other
than of pure Asbestos.

** CHEKKO *’ Brake Linings easily outlast
many times all others, and are, therefore, not only
the best in quality, but also far the cheapest.
