the exhibit is so arranged that visitors may easily inspect each grade of belting displayed. The second division, or Panel Exhibit, is one of the most elabor- ate exhibits in the Machinery Palace. Here is found an interesting display of various cuts of leather, the company's different brands of lace leather, also round, twist and built-up round belting, all of which is particularly interesting to users of these various products. It is well known that certain portions of the hide are not suited for belting purposes, yet when sorted and specially finished they are unsurpassed for manufacturing leather sundries. The major por- tion of this Specialty Exhibit is a demonstration of the manner in which the Graton & Knight people utilize the leather which is un- suitable for use in their high grade belting. It is both surprising and interesting to note the great variety of leather sundries shown, prin- most difficult drives in factory experience, and are all successfully belted, not in accordance with theory, but as a result of many ex- haustive tests and sixty-four years' experience in manufacturing lea- ther belting for all conditions of service. The drives shown in the accompanying illustration of this operating exhibit are as follows:— 1— "Vi in- single strand "V" belt drive. 2— Cone drive (textile machinery). 3— Mule drive in horizontal plane. A—Bicycle drive (cotton mill spinning frames). 5— -Vertical drive with weighted idler. 6— Quarter-turn drive with two idlers. 7— Mule drive in vertical plane. 8— Five strand 1% in. "V" belt drive reduction ratio 7 to 1. 9— —Quarter-turn drive without idler.
