Description: |
| The form is of breast drill with that familiar chuck used on many of Peck Stow and Wilcox's boring tools. Peck's patent text is a couple of pages long. The following excerpt shows Peck's thoughts on the state of the art at that time. (1884) "Breast drills, though less likely than bit-braces to be twisted out of the axis of the hole being drilled, and allowing a freer use of the arm, have not replaced bit-braces, because a handle suitable for running small drills with great speed could not conveniently run a bit where considerable power was required, and a tool large enough for that was cumbersome. To overcome this difficulty bit-braces have been made with varying sweeps from six to fourteen inches. Breast drills, being more expensive, could not replace one or two sizes of the bit brace; but the object of my invention is to furnish a tool which will perform the function of many sizes, and thus replace a variety of tools. The device is intended, as seen, for use in place of the common brace---the brace that multiplies the rotation of its crank, the common ratchet-brace, and the heavy ratchet-drill." You need to look at the patent text for the details. |
