Description: |
| The patent drawing shows the #75 Yankee "push brace". Fegley and Leopold's goal was to make a drill to be "....used in places difficult in access but which can be reached by a comparatively long tool, such as in car work, cabinet work, etc....." They also positioned the ratchet selector at the top where the operators hands were. And they installed a heavier, three jaw chuck. In the 1912 catalog they explained why they called this tool a brace. "It excels a bit brace in its greater rapidity and convenience in the lighter work ordinarily done by brace." |
