PROVISIONAL SPECIFICATION.
A Swivel Ended Wrench with Plunger Locking for Holding Tools.
ALBERT COMLEY, of No. 2 Fair Oak Avenue, Maindee, Newport, Mon., a
Pattern-maker, do hereby declare the nature of this invention to be as follows:-
The wrench consists of a lever handle in wood or iron, for boring or tapping holes
where the ordinary auger handle or tap wrench cannot be used. In one end of the
lever handle is fitted a small iron swivel between two cheeks and made to revolve
half a circle and in the centre is a tapering square hole into which the bits or taps
are placed and are prevented from dropping out by a round plunger or lock held in
position by a flat steel spring and fitted in a round hole on the side of the iron
swivel, allowing half the hole only to cross the square hole in swivel, the other half
of hole being in the side of the bit thus forming a round hole when in its place into
which the plunger goes locking the bit or tap very firm. The wrench is also fitted,
as in the ordinary wrench, with a socket for tap or bit which socket is also fitted
with the plunger lock.
My claim is for the swivel end of wrench and the plunger fastening for the tools.

COMPLETE SPECIFICATION.
A Swivel Ended Wrench with Plunger Locking for Holding Tools.
I, ALBERT COMLEY of 2 Fair Oak Avenue, Maindee, Newport in the County
of Monmouth, Pattern Maker, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
The improved wrench, brace, or boring tool holder according to my invention
consists of, Firstly-A locking device, or plunger operated by a spring fixed upon
said wrench in such a manner that the bits, augers, gimlets, or other like tools
placed therein, may become instantly locked in position, and as easily unlocked
when necessary for the purpose of removal. Secondly-Of an improved swivel
attached to either, or both ends of said wrench, or brace, in which the boring tool
may be placed, the object of my said invention being to enable the operators using
such bits, to bore holes in obscure, or awkward corners, or places, that are
absolutely incapable of being reached by any boring tool held by the type of
holders, or braces hitherto made and used."
In order that my invention and the manner of its operation may be fully and
clearly understood, I have appended the accompanying sheet of drawings, in
which
Figs. 1, and 2, are views of my improved tool holder, or handle, shewn in
different positions in order that its construction may be clearly defined.
Fig. 3 is a longitudinal section of Fig. 2, shewing how the swivelled tool holder
is connected therewith, and in what manner the spring, and plunger operates
therein.
Fig. 4 is a view of the spring and plungers as adopted and used in connection
with Figs. 1, 2 and 3.
Figs. 5, 6, 7 and 8, are front view, back view, top view, and sectional side view
of the swivel tool holder, detached from Figs. 2 and 3.
Fig. 9 is a view further illustrating how a centre bit, or other boring tool fits

page_text: within said swivel, also shewing how a semi-circular recess formed in said tool, and
similarly in the swivelled holder, form collectively a circular recess for the reception
of one of the locking plungers upon the spring Fig. 4.
Fig. 10 shews the application of said spring and plunger to an ordinary
carpenters, or similar brace.
Fig. 11 shews an alternative method of constructing the handle, or swivel holder
to enable the operator to bore holes in obscure places, not accessible when the tool
is held by ordinary holders.
Similar letters are used to indicate corresponding parts throughout the drawings.
In carrying my invention into effect I construct a tool holder, or lever handle A,
of wood, metal, or other suitable material, in the centre of which I provide a
tapered square, or other shaped hole B. At either, or both ends of A. are metallic
pieces C, D, both of which may be detachable and connected to A by screws, or the
like, or one may be formed integrally with A if desired, and the other connected as
described. In the free ends of C and D is placed the metallic swivel tool holder E,
the lugs c and d of which pass through and fit freely in holes a and b bored, or
otherwise formed in C and D for that purpose, said tool holder E, when placed in
position between C and D presents to view three flat and one circular sides e, f, g
and respectively. A tapered square, or other shaped hole passes through E, at
right angles to c, and d, its larger end i being in the side, and its smaller end; in
the circular side . A circular hole k is bored, or otherwise formed centrally in the
lug c, of E, which extends through, and forms a semicircular recess in one side of
the hole ij. A hole F, is also bored or otherwise formed through A, creating a
semicircular recess in the tapered hole B, similar to that in ij. A flat spring G,
Fig. 4, having swivelled thereon, two circular locking plungers
is screwed,
or otherwise fixed upon A, in such a position that m, and n, pass down into the
holes and F respectively as shewn in Fig. 3.
m and
n,
The bits, or other boring tools in general use are square tapered at their heel
ends, and provided upon one face of said taper with a semi-circular recess for the
reception of some kind of holdfast, usually a thumb screw, to prevent them from
falling out of the tool holder. The tapered hole B, in A, and the tapered hole i j,
in E, are for the reception of the said tapered square ends of the boring tools, and
the semi-circular recess in B and i, j, and the semi-circular recess in the tool,
collectively form a circular recess for the reception of the locking plunger m, or n,
when the tool is in position. The manner in which the tool H fits within the
tapered hole in E, or B, and the position of said circular hole or recess is clearly
shewn by Fig. 9.
When H is to be placed in E, the end of G is raised, which brings m out of the hole k,
or when H is to be placed in B, the opposite end of G, with n, is raised, as shewn
by the dotted lines in Fig. 8, and when H is in position in either B, or ii, the
spring G is released, and the plunger m or n holds H firmly in position, from which
it cannot be removed until that end of G is again raised, and as G is preferably
level with the surface of A, the same does not in any way interfere with the hand
of the operator, when in use. The swivels E may be made with various sized
holes ij, to suit an equal variety in the sizes of the tools H, and it will be under-
stood from the foregoing description that the tool in E can be used at right angles
to, or in the same plane as A whichever may be needed.
When the handle A. is of wood, the detachable parts C and D would be of metal,
and the tapered hole B, would be made in a suitable metallic piece B¹, inserted
in A, but when A, is made of metal the insertion B¹ would be superfluous, as B
could be formed in A direct, and one of the pieces C, D would preferably be formed
integrally with A.
The swivel E, having three flat and one circular side, the same is capable of
being turned to the extent of one half circle, so that the tool therein may be
employed for boring holes in obscure, or out of the way places, in a manner not
hitherto attained by any of the holders in general use.
I may employ the spring and plunger, or approximately one half of Fig. 4, in

page_text: connection with a carpenters, or other similar brace K, by attaching it thereto in
the manner shewn by Fig. 10.
Or I may construct the handle A, in the manner shewn by Fig. 11, in which
This
case, I should dispense with the spring G, and its plungers if needed.
arrangement enables holes to be bored in places not easily reached by Figs. 1 and 2.
The parts C, and D, would retain E, in the same manner as that previously
described, a cross head may be formed upon A, if needed to facilitate the turning
thereof.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1st. The construction and use of an improved wrench, or holder for bits, and
similar boring tools, consisting of the several parts described and shewn, combined
and operating, substantially as herein set forth, and for the purposes specified.
2nd. In an improved wrench, or holder for bits, and similar boring tools, the
employment of a handle A, with central tapered hole B, and lateral bore F, and
provided at either, or both ends with detachable pieces C, or D, or C, and D,
carrying a swivel E, within holes a b. The spring G, with plungers m and n,
operating within E or B, or E and B, for retaining therein a boring tool H, sub-
stantially as and for the purposes herein described, and shewn by Figs. 1. 2. 3
and 4 of the accompanying drawings.
3rd. In an improved wrench, or boring tool holder, the construction and use of a
swivel E, as set forth in the preceding claim, having lugs c, d, in one of which is
bored a hole k, partly absorbing a hole ij, and forming a circular hole with a semi-
circular recess in a tool H for the reception of a locking plunger m or n upon a
spring G substantially as described and shewn by the appended drawings, reference
being had to Figs. 5. 6. 7 and 8.
4th. The improved handle A with swivel E, substantially as described and
shewn by Fig. 11 of the accompanying drawings.
Dated this 31st day of July 1891.
