Indications Point to a Probable

Coal Shortage.

The rapidly increasing use of automatic stokers and the demand for screenings
is growing to such an extent that even under average conditions, many
operators are unable to meet the demand for Fine Coal.

In case of a serious shortage, will you be
compelled to substitute Run - of - Mine
Coal, while your boilers are equipped
for stoker sized coal, which means in-
creased Fuel Cost and Loss of Heat
Value ?

Or, will you be offering fabulous prices
for coal, with the possibility of not getting
enough to keep your plant running ?

Overcome Situations of this
kind by installing a

A

Kt

J effr ey

Single Roll

Crusher

which will, in a single operation, reduce your Run-of-Mine to 4 in.
or 1 in., the proved size for maximum stoker efficiency.

This machine can be installed with various types of elevating and conveying
machinery. Our twenty-five years of experience in building Coal Handling
Machinery puts us in position to furnish you with anything you may need
in connection with the crusher, as well as a coal storage equipment suitable
for emergency conditions.

The Jeffrey Single Roll Crusher cannot be stalled under load—is protected
against foreign material by an efficient safety device, is adjustable to make
different products without changing equipment, is cushioned against sudden
shocks, has renewable bronze bushings in the bearings, has renewable
segments with long teeth renewable independent of the whole segment, &c.

If you are interested in securing a constant supply of small
coal—ask for copy of Bulletin No. 141-32, fully illustrating
this machine, describing its construction and the results
which it is capable of producing.
