I he Elevator stops running as soon as
the hoppers are full and starts itself
when the shoots are about half empty.
There is thus always a sufficient supply
of coal, with no overfeeding, and less
wear and tear, whilst close attention to
the Elevator can be dispensed with.

Bennis Conveyors
and Automatic Elevators for the rapid
and economical handling of coal and ash.

The illustration shows a "Bennis" Elevator
fitted with Patent Self-Starter and Stopper.

This ingenious appliance can be applied
to any existing Elevator as well as in-
corporated in the new.

It is arranged to render the Elevator
automatic in action.
