Description: |
| "Let us consider, for instance, the dryer gears, as used in many paper mills, having a diameter of four to seven feet, a four to ten inch face, meshing in a group of twenty to sixty in a single paper machine, driven from motors totalling up to a thousand horsepower; half of these gears should be made with non-metallic teeth to resist the velocity of nearly two thousand feet per minute now required to satisfy the increased paper demand." |
