Advantages of Patent Flattened Strand Ropes.

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

8. 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-tvisting.

GUIDE.

Write to the Manufacturers for
details of their Carbic Portable
Welding and Cutting Plants:

How’s the Welding
Plant working?”

“ Fine. The Carbic Cake
is a big improvement on
the old method. Genera-
tion goes on evenly at a
low temperature — that
means more constant
pressure and purer gas.
There’s no wastage as
with ordinary carbide,
the generation of gas
only taking place while
water is in actual contact
with the Carbic Cake.”
“Short-handed as we
are, the simplicity and
easy handling of the Car-
bic System is a great
advantage. ”
