PROVISIONAL SPECIFICATION.
A Universal Jointed Brace for Boring Holes close to Washboards,
in Door Cheeks, Corners, and similar Places.
ARTHUR ALBERT TATTERSALL, 39, Havelock Street, Stoke on Trent, in the county
of Staffordshire, Draughtsman and Engineer, do hereby declare the nature of this
invention to be as follows:-
This Invention relates to a universal jointed brace, for boring holes close to wash-
boards in floors, in door-checks, corners, and similar places close to the wall, where an
ordinary brace would not turn round.
And consists in an ordinary cranked brace, turning a universal joint, which works
a spindle, working, at any convenient angle, another universal joint, which universal
joint works another spindle containing bit or drill head.
The brace, universal joints, spindles, and bit or drill head are held in any convenient
manner, in suitable framework, on the top of which is secured a breastplate, to allow
of the pressure being put on the frame.
The drill or bit is secured to the drill or bit head in any convenient manner.
The handle of the brace turning in its framework, works a universal joint; this
works a spindle, which works, at any convenient angle, another universal joint;
working another spindle, with bit or drill head.

COMPLETE SPECIFICATION.
A Universal Jointed Brace for Boring Holes close to Washboards,
in Door Cheeks, Corners, and similar Places.
I, ARTHUR ALBERT TATTERSALL, formerly of Stoke on Trent now of 31 Dixon
Avenue, Crosshill, Glasgow, County of Lanark, Draughtsman and Practical Engineer,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement -
This invention relates to a universal jointed brace for boring holes close to wash-
boards, in floors, door cheeks, corners and similar places close to the wall where an
ordinary brace would not turn round. And it consists in an ordinary cranked brace
turning a universal joint, which I call a Hooke's joint, a hook and eye joint, or a two
eyed joint as hereinafter described. This joint works a spindle which works, at any
convenient angle, another universal joint, which, in its turn, works another spindle
containing a bit or drill head.
The cranked handle, universal joints, spindles and bit or drill head are held in any
convenient manner in a suitable framework, on the top of which is secured a breast-
plate, to allow of the pressure being put on the frame.
The drill or bit is secured to the drill or bit head in any convenient manner.
The handle of the brace turning in its framework, works a universal joint, this
works a spindle, which works, at any convenient angle, another universal. joint,
working another spindle with bit or drill head.
And in order that my said invention may be properly understood I have bereunto
appended an explanatory sheet of drawings whereon,
Fig. 1. shows in front elevation one arrangement of my improved universal-jointed
brace.
Fig. 2. shows in front elevation a modified arrangement of the invention.

page_text: Fig. 3. shows another modification of the invention. Referring to the drawings
whereon the same reference letters wherever repeated indicate similar or like parts.
In fig. 1, A, is an ordinary revolving cranked handle, which turns in a frame-
work B, having for the hand a loose ferrule C. The cranked handle A has spindles or
pivots D D', shown dotted, one at each end, which are free to revolve in bearings B¹
in the frame B. There is fitted on the spindle D a semicircular or other shaped
arm E, working in which is a cross F, which works at a convenient angle, another
semicircular or other shaped arm G. The arm G in its turn works a spindle H,
shown dotted, contained in a barrel B³ preferably made in one piece with the frame B.
The spindle H works a semicircular or other shaped arin I into which works the
cross which latter turns another semicircular or other shaped arm K. This arm K
is fitted to and turns another spindle L contained in the barrel B3 which is preferably
made in one piece with the frame B. The barrel B³ contains a bit or drill head into
which is secured by means of a setscrew M, or other suitable fixture, the bit N.
It will be seen that the banille A, pivots D D1 and joints E F G, spindle H,
joints I J K and spindle L all work and are contained in the framework B which
may be made of malleable iron or any other suitable material. On top of this frame-
work B is fixed a breastplate to allow of the pressure being put on the framework
and thence on the bit.
On the drawings, figs. 1 and 2, 1have shown an open frame B having the
barrels B and B made in one piece with and virtually constituting a part of the
frame. This construction ensures both lightness and strength. The frame may,
however, he made in any other suitable manner so long as it carries the handle. A
and spindles H and L in their proper and relative positions.
The semicircular or other shaped arms E G and I K, with their crosses F and J,
whose directions meet in a point, and will work up to a certain angle, are called.
"universal" or "Hooke's "joints. The arms of the cross should be equal.
Fig. 2 is a modification of the invention wherein the universal joints PQ and R S
are made hook and eye joints, viz.;-one hook put through an eye, or two eyes, one
put through the other; working in the same framework B and in the same manner
ns fig. 1, except that the breastplate T is shown as a double bridge of metal, or it may
be a single bridge, to which is socurod a semicircular or other, shaped piece of wood,
for the hand to hold whilst the brace is being worked.
Fig. 3 is another modification of the invention wherein the upper part of the frame
is dispensed with and the lower triangular part has a handle U made of a double
bridge of metal, or it may be a single bridge of same, with a semicircular or other
shaped piece of wood secured to it. In this arrangement the revolving handle A is
separate from the rest of the brace and can be fitted on the spindle D when the brace
is to be used.
The handles T, U, can be made in any suitable manner to allow a firm grip of the
top of framework.
The drill or bit N is secured to the drill or bit head by a screw M, or by an opening
and closing motion, so as to take in any convenient size of bit.
The object of this invention is to make a brace that will bore holes close to walls,
in corners and similar places, and that can, with ease, be held firmly and steadily at
it's work.
The handle A of the brace, turning in its framework B, works the universal
joint E F G or PQ, this universal joint works the spindle H, which, in its turn, works
at any convenient angle the second universal joint I J K or RS, working the spindle L
with the bit or drill head.
By continuously turning the handle A which works joints EFG, IJK, or PQ
and RS, with bit N, all contained in the framework B, holes can be bored close to
the wall, or any corner. The brace works continuously and does away with the slow
system of the ratchet brace or the unsteady movement of the one universal joint in
its moveable or immoveable stock.
If desired a universal joint on the ball and socket or equivalent principle can be
used instead of the Hooke's or the hook and eye joint.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the sama is to be performed, I declare that what I
claim is;
a
(1) A brace having a framework in which is carried a revolving handle driving
spindle placed at an angle to the axis of rotation of said handle and which, in its
turn, drives directly or indirectly the bit or drill, substantially as and for the purposes
set forth.
(2) A brace having a framework in which is carried a revolving handle which, by
means of a universal joint, turns a spindle placed at an angle and which, in its turn,
by means of a universal joint, drives directly or indirectly the bit or drill, substantially
as hereinbefore described.
(3) The combination of the revolving handle A, universal joints E G, IK, with
crosses F and J, and the spindles DD H and L, all contained and working in a
framework (B) of any suitable shape, substantially as hereinbefore described and
shown at fig. 1 of the annexed drawings.
(4) The combination of the revolving handle A, the universal hook and eye joints,
or eye joints PQ and RS, with spindles H and L, all contained and working in
a framework (B) of any suitable shape, substantially as herein before described and
shown at fig. 2 of the annexed drawings.
(5) The combination with an angular spindle (H) carried in a suitable frame (B)
of two universal joints one at each end of the spindle the upper one being driven.
by a revolving handle, which may be carried in or be separate from the frame,
and the lower one driving directly or indirectly the bit or drill, substantially as
herein before described.
