Improvement in scroll-sawing machines
|
George E. Lewis |
Seneca Falls, NY |
The table is cast in a single piece, including a hollow ball under its center. The blade passes through the middle of the ball, and the base of the saw clamps the ball—and hence the table—at the desired angle.
This patent was first used on the "Boss" model scrollsaws made by the Lewis Brothers of Seneca Falls. It was later used on the "Empire", "Rival" and "Victor" models from Seneca Falls Mfg. Co., which were heavy-duty treadle-powered scrollsaws intended for factory use. The Empire was introduced in 1884. The Victor design is essentially identical to the patent drawing, and most likely the design and patterns were purchased from Lewis Bros. |
