Description: |
| "The variable speed drive of the invention is based upon the novel concept of mounting a variable speed driver member and an independently supported low speed shaft in a position such that they may rotate about a common axis of rotation. With this specific combination, there is provided special clutch mechanisms for selecting driving the low speed shafts... I have found that I may, by this basic arrangement of parts, which involves rotation of two independently supported members along a common axis, very material reduce gear noise and provide for highly desirable variable speed drive operation, especially characterized by quietness and smooth running qualities..." |
