In order to get the highest rate of production, it is neces-sary to have the lathe supplied with a full set of tools, includ-ing flange tools and forming tools for the tread, as well as tohave conveniences for getting the wheels to and from The Niles-Bement-Pond Company recommends the follow-ing procedure in handling wheels in connection with thePond steel-tired wheel lathe: The lathe should be set level with the floor, and provided. WHEEL LATHE FOR TURNING STEEL-TIRED WHEELS AT SHOlS OF INTEKUOROUGH RAIlD TRANSIT COMPANY and Forty-Eighth Street and Seventh Avenue, New York City. The question of getting power enough in the machine toturn steel-tired wheels is simple when compared with the diffi-culty of holding wheels rigidly so that the full power of themachine can be used in the tools. In the lathe illustrated,special saw-teeth drivers engage the tire directly, the teethof the drivers being forced directly into the tire by set the other side of the tire, chuck jaws grip it firmly, sothat the tires are wedged between the driving plates and theface plates of the machine, thus doing away witli any chancefor chatter or vibration. The machine is driven by a verylarge central gearwheel. A section of this gear is made re-movable, so that the wheels can be rolled in. This construc-tion makes a very compact machine and one of great power. This type of machine has long been used by
