In connection with the pivot of this wheel, arrangements are made-which provide for the perfectlubrication of the rubbing surfaces with clean oil. The lower end of the upright revolving shaftenters a stationary pivot-box K, through an opening made oil-tight by hemp and leather packing. 1936 HYDKAULIC MACHINES, VAEIETIES OF. Within the box there is a small stationary steel plate on which the shaft revolves. Within thebos, also, there are two oil-chambers, one situated above and round the rubbing surface of this 4075.
