BINATION DRILL BRACE."
PROVISIONAL SPECIFICATION left by the said Edward Davies and
Richard Hobbs Taunton at the Office of the Commissioners of Patents,
with their Petition, on the 28th August 1865,
We, EDWARD DAVIES, of Birmingham, in the County of Warwick, Engineer,
-and-RICHARD HOBBS-TAUNTON, also of Birmingham, aforesaid, Tube Manu-
facturer, do hereby declare the nature of our said Invention for "AN IMPROVED
COMBINATION DRILL BRACE," to be as follows (that is to say):-
Our improvements in the combination brace named in the title consist in. so.
constructing it that it may be used either as a ratchet or swing brace, with all
the appliances for regulating the pressure for advancing the drill necessarily
used with such apparatus. To effect this we divide the bow of the brace in
any convenient part, either to form a handle or for the convenience of applying
an additional lever handle when using the apparatus as a ratchet brace, as
may be required according to the weight.of the work under, operation. When
using this brace as a swing brace, we re-connect the top and ratchet part
together in any convenient part of the bow, or otherwise in such a way, either

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of August, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Edward Davies and Richard Hobbs Taunton, Her special license
that we, the said Edward Davies and Richard Hobbs Taunton, our executors,
administrators, and assigns, or such others as we, the said Edward Davies:
and Richard Hobbs Taunton, our executors, administrators, or assigns,
should at any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully.
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "A COMBINATION DRILL BRACE," upon the condition (amongst others)
that we, the said Edward Davies and Richard Hobbs Taunton, by an instru-
ment in writing under our hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same,
was to be performed, and cause the same to be filed in the Great Seal Patent,
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that we, the said Edward Davies and Richard Hobbs
Taunton, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement (that is to say) :-
Our improvements in the combination brace named in the title consist of so:
constructing it that it may be used either as a ratchet or swing brace, with all
the appliances for regulating the pressure for advancing the .drill necessarily:

page_text: used with such apparatus, which may also be arranged for carrying taps and
dies or cutters for cutting off the ends of tubes or facing the bearing of holes.
To effect this we divide the bow of the brace in any convenient part or parts,"
either to form a handle, tubular or otherwise, or for the convenient of applying
an additional lever handle, which also may be tubular, if so preferred, when
using the apparatus as a ratchet brace, as may be required, according to the
weight of work under operation. When using this brace as a swing brace,
we re-connect the top and ratchet part together in any convenient part of the
bow or otherwise, in such a way, either by a screw or screw pin and socket,
or by using an additional tube, which may form the double purpose, first, for
holding in the hand while working, and, secondly, for forming a socket .or
secure means for holding the parts together:
But as our Invention will be best comprehended and understood by re-
ferring to the Drawing hereunto annexed, we will proceed to describe the
same, reference being made to the Figures marked thereon.
:
DESCRIPTION OF DRAWINGS.
Fig. 1 represents in a vertical side view our improved combination drill
brace arranged to be used as an ordinary swing brace, with the screw A for
obtaining the necessary pressure for advancing the drill B as it progresses with
its work. In this view we, have represented the lower angle part of the
handle C reduced to form. a pin, which enters in a corresponding hole in the
part D, in which position it is retained by the screws E and F, the reversing
of which will permit the part D to be removed altogether from the handle C,
to permit the part D to be used as a ratchet brace, by inserting into the same
socket represented in dotted lines at a, a, a suitable extended lever handle, as
represented at G, Fig. 2, which exhibits. the parts arranged as for a ratchet
brace. In this view we have omitted the drill exhibited marked B, Figure 1,
and we have exhibited the regulating screw A of that Figure here inserted in
the part for the same object and purpose as in that Figure, viz., for.
affording the necessary pressure for advancing the drill. The spring stop
that presses on the pall J is marked I, secured by screws marked b and c, and
the ratchet itself is marked K, in which details there is no material difference
of arrangement to the ordinary ratchet brace.
Fig. 3 represents the lever handle G with the ratchet part in section, and
5 with an additional screw at the back marked L, if required, for further security
for holding in the handle G. d is the axis on which the pall J works, the
hollow axis of the ratchet marked H projects up above the stock D, as
exhibited in Figures 1 and 2, and may receive an additional collar for holding

page_text: it in position while its lower part, not seen in this view, forms the stock for
receiving the drill as exhibited, marked M in Figures 1 and 2. This same
part we have exbibited in a separate side view at Fig. 4 with an adjustable
collar at the top and a wedge, so as to form a socket for holding dies for
screwing such as the ends of gas tubes, &c., for which purpose it may be found
tiseful, the tube being passed up through the centre. At the lower part of the
'stock we have exhibited the outer end of a cutter, marked f, held in position
by an adjusting screw f, which is held by the cutter h, the collar h being
secured to the stock N ; while on the other side we apply a set screw k, which
holds the work up to the cutter while the cutter is performing its work; these
parts we have exhibited in a vertical section at Fig. 5, showing the collar O,
wedge, and dies m and n, with the cutter f, screw g, and collar h, h, as also
the regulating screw k.
"
Fig. 6 represents a top view of the collar O, as also the dies m and n, with
the wedge l, which is actuated by the screw p for closing the dies as the
process or work of screwing proceeds.
In some cases where lightness may be desirable, the part C in Figure 1, as
well as the angles exhibited in dotted lines marked P and Q, may be hollow,
viz., the ordinary tubing and angles as used for gasfitting, the parts being
tapped and screwed together; and we have exhibited this arrangement in
connection of the handle C and angle Q, with the stock or ratchet part D at
Fig. 7, the end of the part D terminating in a pin for screwing into the angle,
and when carrying out this arrangement for a ratchet, and dispensing with
the handle C angle Q, we purpose applying a tubular lover handle instead
of a solid one, as exhibited at G, G, Figures 2 and 3, which tubular handle
we have exhibited in section at Fig. 8, the part p being intended to be
screwed on or over the shank R, Figure 7, which may be further secured by
a set screw if necessary. And with a view of further utilizing this part, a
steel claw may be applied, as exhibited marked S, its shank being fashioned
to simply fit in the tube, or tapped and screwed, as preferred'; the extreme end
marked t may be divided as the claw of an ordinary claw hammer, thus making
it serviceable as a short lever.
Having thus given a general description of our Invention, and the manner.
in which the same may be carried into effect, we wish it understood that we
do not purpose limiting ourselves to the exact details herein described and 3
exhibited, as the same may be varied without departing from the spirit of our
Invention, as, for instance, the handle C, instead of being as here shown, may
be so formed and fashioned as to form a curve so as to combine the part C
and Tin one, and dispense with the use of the angles P and Q, and in like

page_text: manner other details may be modified; and we will observe that we set up no
claim whatever or pretension to novelty in the application of the claw S to the
tubular handle as exhibited at Figure 8, as iron levers have been before so
constructed; but what we claim and wish to protect by these our in part
recited Letters Patent is is, the combining the action and qualities of an ordinary
swing brace with a ratchet brace for the object and purposes herein described
and exhibited.
In witness whereof, we, the said Edward Davies and Richard Hobbs
Taunton, have hereunto set our hands and seals, this Twenty-fourth
day of February, in the year of our Lord One thousand eight hundred
and sixty-six.
