The Beiliss Engine, with
its automatic Forced Lub-
rication and Absence of
Wear, is specially adapted
for operating Mine Ven-
tilating Fans, and can be
depended upon to run con-
tinuously day and night for
many months without the
necessity of stopping for
adjustment. It is not un-
usual for these engines to
run for one, two or even
three years without ad-
justment.
