This invention relates to an improvement in bits, especially designed to be used by oabinetmakers and others, forI attaching wood knobs to drawers, tc.
Such knobs are now commonly consu-noted with a Wooden screw, made a part of the knob; and to attach such knobs, a hole is first bored with a common bit,
of the propel' size, and afterward, by another instrument, the hole is tapped to cut a corresponding thread in ,the hole for the insertion. of the knob-screw.
The object of my invention is to construct a bit with thetap' ycombin-d, so that-the same instrument, following through the l1olc,.\vill ont the thread in theihole. u
'Tolenable others skilled in 4the -art to make and use my invention, 1 will proceed to describe the sume, usl
illustrated in the accompanying drawings.
A is the bit, ot any convenient form orknown constrction, preferring, as here represented, asingle-twist auger-bit. It is made short, inasmuch us-'itis'only` required to bore, through the fronts oi drawers, and the like..
Directly abovethe twist, and so that the ltu'istot' the bit will form-a guide, [construct the tap B, by cutting two or more threads larger than the barrel ot' the bit, so that the said thread will follow the bit through the hole, and cnt the thread therein.
Above the thread theshzmk is formed in the usual manner, and the bit is used in the common brace or other suitable instrument.
Having fully described my invention,-
\Vliat I claim as new nud useful, und desire to sec-uro by Letters Patent, is
The bit and'tap, constructed and combined in onev and the same piece, as shown and described, :is un improved article of manufacture.
