Sullivan Machinery Co.

Salisbury House, London, E.C.

The Continuous Chain Feed

gives Sullivan Ironclads the evenest and steadiest feed ever
devised,—not an intermittent motion, but a continuous one. This
reduces the wear and tear and is one of the reasons why they
are the cheapest to maintain and cut the cost of holing.

The Friction Haulage

acts as a safety valve and permits the use of a high feed with-
out danger to the machines.
