Application 09/320,149
THE INVENTION
The appellants claim a conveyor system having a specified
lubricator. Claim 21 is illustrative:
21. A conveyor system comprising:
a guide track having a guide surface and an aperture;
a conveyor chain supported by the guide track for movement
relative to the guide track, the conveyor chain including a
plurality of interconnected links, a lower surface of at least
one link contacting the guide surface of the guide track when the
conveyor chain is moved by a drive means; and
a lubricator including a chamber for storing a lubricant and
means for forcing lubricant from the chamber through an outlet in
the chamber, the outlet of the chamber being in fluid
communication with the aperture in the guide track, the means for
forcing lubricant from the chamber continuously forcing lubricant
from the chamber and through the aperture in the guide track when
the means for forcing lubricant from the chamber is connected to
a source of electric current contained within the lubricator,
the outlet of the lubricator and the aperture in the guide
track being connected in fluid communication by a conduit and an
adapter block, the conduit being connected to the outlet of the
lubricator and a port in the adapter block, said port being
oblong and presenting a single stream of outwardly flowing
lubricant, and said port having a longitudinal axis transverse to
the direction of said movement of said chain, the adapter block
being connected to the aperture in the guide track, the adapter
block having a projection dimensioned to fit into the aperture in
the guide track and having a passageway extending from the port
to an opening in the projection whereby lubricant is forced from
the chamber through the conduit and out of the opening in the
projection in the adapter block,
