requiring it, by automatic feed action from one reservoir.

=2320. Syphon wick lubricator.=

=2321. Automatic lubricator,= with intermittent feed. The revolving spindle is driven from the engine by a ratchet and pawl motion, and has a recess in it which in revolving delivers its contents of oil into the tube below.
