Here is an 18" SparOak Belt on a hard drive in a warm, moist atmosphere where the extreme flexibility of Spartan and the firm- ness of Oak leather are necessary. SparOak is the answer to a great many perplexing belt problems, saving power and standing up under the most severe conditions. If you have a troublesome belt drive, con- sult us as to what belt is required. Maybe it is SparOak, but in any event one of the Graton & Knight Standardized Series of Belts will fit exactly. Write for our booklet on Standardized A Rugged Pulley-Gripper There is nothing like leather for belting, and SparOak Leather Belting has peculiar advant- ages all its own. SparOak is a two-in-one belt combining rug- ged strength with unique pulley-grip. Its great endurance and minimized slip make it a double-service belt of unusual qualities. Two kinds of leather enter into a SparOak Belt. The outer ply is oak tanned, cut from the best selected center stock. The ply next the pul- ley is Graton & Knight Spartan leather, tanned to give pliability and traction power unequalled by any other material. parOak Belting SparOak Belts grip from the start. During the weeks most new belts take to "work in," a SparOak Belt is giving full power and keeping production up to normal. And SparOak Belts keep on gripping for years under adverse con- ditions. They withstand repeated shifting, and the wear against step cone or flange pulleys. They render efficient service on drives with high speeds, small pulleys, and heavy loads. In short, any of the factors that quickly wear out ordin- ary belts affect SparOak belting amazingly little.
