Pig. 13a. SINKING.

1.	Greater wearing surface, therefore longer life of rope and less wear

upon pulleys.

2.	Greater strength, thereby admitting of smaller ropes being used for

existing loads, or of increased loads without increase in size of rope.

3.	Spliced easily and more effectively.

4.	Less tendency to twist and stretch in working.

Fig. 13a for Sinking and Fig. 11b for Cranes, &c., are non-twisting.

IT WILL PAY to overhaul your Elect-
rical Plant periodically, laying out Armature
and Field Coils, and, after cleaning off dirt and
grease with a cloth wet with benzine, to give
them a Fresh Coat of Varnish. This will
Strengthen Weak Spots which may be de-
veloping in the insulation, and thus ward off
a Possible Breakdown.

The Varnish essentially suitable for this is

INSULAC INSULATING COMPOUND.’’
