A method of applying a hub lubricating pipe to driving have brass hub liners cast on is shown in the drawing. ANo. 20D. wire nail is inserted in a piece of Y^ in. copper pipe,about 2 in. long, and the end is allowed to extend into the oil. A Method of Ap hole, as shown. The pipe is then held in the proper positionwhile the liner is being poured. After the hub liner is appliedthe nail is removed and the end of the pipe is cut off and cham-fered, as shown in the illustration. IRON RACK FOR SHORT LENGTHS BY W. H.
