Advantages of Patent Flattened Strand Ropes.

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.

GUIDE.

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

that the Carbic System is
the most economical be-
cause the generation of
gas only takes place while
water is in actual contact
with the Carbic Cake.
You shut the generator
down at night and start it
up again in the morning,
to find that no deteriora-
tion of the old charge has
taken place. Each Carbic
Cake is guaranteed to pro-
duce a stated number of

cubic feet of acetylene
either by continuous or
intermittent use.
