<p>A bottle transporting table, somewhat like a spoked wheel, revolves about a vertical axis. A plurality of vertical shafts are angularly spaced around the rim region of the wheel and the top end of each shaft has a bottle supporting turn table fastened to it. The shafts are journaled on a thrust bearing and a radial bushing fixed in the top of the rim region and the bottom ends of the shafts extend into a cavity at the bottom of the rim which is created by fitting complementarily with a lower stationary ring. A pair of vertical bores or ducts are formed in the rim parallel to and radially spaced from the turntable shafts and their bearings. A seal forms an annular channel over the bearings and bores. A nozzle fed from a pump projects lubricating oil into one of the bores adjacent each shaft as these bores orbit with the rim. The channel enables the lubricant to be conducted to the bearings and the other bore enables lubricant to be recirculated back to a reservoir.</p> |
