Description: |
| "The object of my invention is to provide a circular saw which shall be in the nature of a hand-tool for cutting thin lumber; and it consists in a plate having near its middle and at its lower edge a small circular saw loosely revolving in a bearing, and having in front and rear of the same, and slightly projecting below the lower edge of the blade, a gear-wheel which, as the plate is steadily pushed over the surface of the board, bites the latter, and through a train of gear-wheels imparts a rotary motion to the saw, which, as the plate advances, cuts a kerf through the board with a circular sweep..." |
