The figures below represent a brace
which has recently been put on the market by Amidon & White of
Buffalo, N. Y., for whom W. H. Goldey is agent in this city (New
York), at 103 Chambers street.
The general form of this brace is
shown in Fig. 11. The feature of special interest in this
implement is the contrivance, which has been admired as
ingenious and efficient, by which the power and motion are
communicated to the bit.
This is done by moans of a
universal joint, the form of which is represented in Fig. 12. In
this cut P is a portion of the arm by which the brace is held in
position and on which the pressure is applied. C is connected
with the sweep, by the motion of which in the operation of
boring it is made to revolve, and through the joint as
represented it gives motion to A, a shaft, which, extended,
carries the chuck which holds the bit, E being a bush and A
revolving inside of it.
The jaws are those of the Barber
improved brace, which is already known by the trade. This brace
is a handsome tool, in full nickel-plate, with black-walnut head
and handle. It is made with 6, 8 and 10 inch sweep.
It will be apparent to our readers
that this brace possesses many advantages, and among others the
manufacturers enumerate the following:
That it bores six
or eight times as fast as the ratchet brace, as the movement is
round and round; that it bores more easily, as it is easier to
turn round and round in continuous motion than back and forth,
and as the pressure comes on the arm of the brace, instead of on
the sweep itself, more power is gained; that for heavy work or
boring into hardwood, and especially for boring overhead, either
in the corner or in the clear, the superiority of the corner
brace is apparent in the advantage gained by the pressure on the
arm; that it will bore close into a corner, the ratchet brace,
owing to its head, not boring a straight hole within 1-1/2
inches of the corner, and that it is not confined in its utility
to work in the corner or against a wall, but that it will do
just as good work in the clear as an ordinary brace.
The manufacturers speak of the
favor with which it has been received by mechanics who have used
it, and regard it as an important addition to the workman's
outfit. It will be seen that it is adapted not only to the
carpenter, but especially to the plumber, gas-fitter,
bell-hanger, and other mechanics whose work calls for boring
which is difficult or impossible with ordinary tools.
