This is a ten-inch-sweep Ratchet Bit Brace, with a gear wheel, speeded about three to one, to be used for drilling iron. When not needed for drilling, this gear wheel can be taken off in one second.

This Bit Brace is made of steel, highly polished and heavily nickel plated, with a cocobolo handle and lignumvitae head.

It has two sets of forged steel jaws, which will hold square and flat shank tools of all shapes and sizes, and round twisted drills from 7-16 to 1-32 inch in. diameter. The ratchet attachment enable the Brace to be used in places where there is not room to revolve the sweep.

Many attempts have been made to imitate the outside appearance of our Barber Improved Braces, but no one dares to use our Patent Jaws, as seen in this cut, and no brace is good without them.

We guarantee these tools to be perfect in every respect, and that they will give great satisfaction to all who use them.

Hardware dealers will furnish them on demand at our prices, or we will forward one by express on receipt of the price, which is Three Dollars.
