By reference to Fig. 3, the barrel, k, will be seen in section, aud some of its details, together with those of the pump and stirrer, may be noticed. The iulcrum, /, has a .foot below, screwed to the barrel. Through its top is a pivot, o, on which tilts the pump-lever, /, which is similarly hinged at b to the top of the piston-rod, t. The pump-cylinder, g, is also hung upon trunnions, i, projecting into eyes. In this illus- tration the eyes, e e, have each a neck fitting in a slot cut through the stave, oppo- sitely from the side of the bung-hole, and beneath the stave is a foot on the eye-piece. Its neck is so short that the eye is held down firmly against the top of the stave, while the foot is as tight against its under surface. The length of its eye-piece is a little than the diameter of the bung-hole, into which it may be inserted to be.
