=Compression grease cups= are used extensively on engines for
lubricating the crank-pin and wrist-pin, also pillow block bearings
for crank shaft; in fact this method of lubrication for all kinds of
bearings and journals is becoming universally adopted.
In construction the Besly Bonanza Cup is simple and durable. The outer
casing is threaded and fits tightly over the bottom part of cup. After
the cup has been put in place, remove the top part, fill it with Helmet
oil or grease and screw it on the lower part for two or three threads.
The cup is then in working order.

To insure a plentiful supply of grease to the journal or bearing, all
that is necessary is to give the top part of cup an occasional turn.
C. H. Besly & Co.’s Helmet Solid Oil is for use in compression cups,
and is a perfect lubricant, in fact it is said to be the best.
