>4 111 IW W X LaLi I and wages are lost, and over 500 men are
injured when such loss and injuries are preventable by usage of the
Hanley Patent Appliances for preventing injury to Cages and men.

These appliances are Safety Belt-Rigs for shaft and scaffold workers;
CAGE ARRESTERS; DETACH HOOKS; ROPE CAPPLES;
GUIDE TENSION GEARS, etc. These are Simple, Practical and
Commercially cheap.

These appliances are recommended only to firms or officials who
decide to risk the trifling cost of “proper appliances for ensuring
safety” (Rule 38) rather than allow their men, cages, and the firm's
bankbook to be without “ proper appliances for ensuring safety ” in the
shaft. As users find them highly profitable tools their adoption is a
Good Commercial Proposition MERELY — safety being an extra
incidental. People give up talking about “safety” and prove their
desires by adoption of things.

All godds supplied on approval.
