Storer's suet lubricator, 1866
This is a cup lubricator, designed for using suet or other grease which requires heat to liquefy it, as sometimes supplied to steam cylinders or large bearings; it was patented in 1866 by Mr. J. Storer. The cover for filling is secured by a bayonet joint, made steamtight by having a sharp edge, which is forced down on a soft metal seating by an external screw. Internally there is a cylindrical strainer to keep back solid matter and prevent choking of the outlet pipe. The rate of feed is regulated by a cock.
