SPIRO-TURBINE SULLIVAN IRONCLADS.

Do You Want to Save Air ?

Air driven Sullivan Ironclad Coal Cutters are supplied
with spiro-turbine air motors.

Careful tests show that these almost indestructible air
motors consume from 25 to 30 per cent, less air per B.H.P.
than reciprocating or piston coal-cutter engines.

If your power costs you |d. per H.P. at your
compressor, a Spiro-Turbine Sullivan Ironclad will

SAVE YOU EIGHT SHILLINGS PER SHIFT
under average cutting conditions, in your power bill alone, over the cost of operating an engine driven coal cutter
of the latest and best type.

If your present compressors are working to their capacity, you can run 25 per cent, more machines by using
Sullivan Ironclads. These machines are widely known for their high cutting capacity and low power consumption
per ton of coal undercut, and fitted with Spiro-Turbine motors represent the highest development in coal cutters.

THE CONTINUOUS CHAIN FEED AND FRICTION HAULAGE
ft

have now proved their merit beyond dispute in British collieries. Those using them say these features are the
greatest improvements in coal cutters in recent years.—“ Ask the man who has one.”

Sullivan Ironclads are especially adapted to hard holing in stone pavement on account of their high power and
great cutting capacity. Under bad roof they excel, as they are only 2 Jr feet wide over all—the narrowest coal cutter
of the power on the market; height 17in. ; 30 H.P.
