d stroke, it is apparent that if the feed wheel is run down against it in the positionshown in the engraving, the pusher will be given its full traverse and the greatest feed. Ifrun back to clear the travel of the agitator, the pusher will, of course, have no motion and thefeed will stop. Between these extremes any desired rate of feed can be given. In like manner, the rock of the grate bars can be adjusted between any limiting angles,and over a range of motion from no movement to full throw, by means of the sheath nut andjam nuts on the connecting rod. By these adjustments the whole action of the stoker iscontrolled, and the fires forced, checked, or banked at will. Stone Breaker : see Ore-crushing Machine Chinas. ST0R.4.(tE batteries.

Text Appearing After Image:
after experiments with various metals, Plante decided upon the use of lead plates in dilutesulphuric acid, because in discharge both plates were active ; that is, not only did the per-oxide of lead plate combine witli hydrogen, but the reduced metallic lead combined withoxygen. Plauies cell was originally constructed with two plates of sheet lead, separated bygutta-percha strips, one sheet bcinglaid over the other, with two gutta-percha strips betweenthem, and two more laid on the upper sheet, as shown at A, Fig. 1. They were then rolled together and clamped, as shown at B, a strip of leail being left attached to the corner of each sheet in cutting China, bywhich connection could i)e made. The sheets thusrolled togetlier were ])hiced in a jar of glass or ebonite,containing a 10 per cent, solution of sulphuric acid.The jar had an ebonite cover, with binding screws towhich the connecting strips were attached ; alsoclamps for holding wires to show the heating effectof the discharge.
