PROVISIONAL SPECIFICATION.
Improvements in Handles for Turnscrews, Gimblets, and other like
Implements and Purposes.
I ROBERT FRANCIS DRURY, of George Street Sheffield in the County of
York, Patent Agent do hereby declare the nature of my invention which is a
communication from abroad by my client Charles Warn, of Stockholm, Sweden,
to be as follows:-
This invention relates to an improved handle for turnscrews and other imple-
ments that require turning by hand, the object being to provide a handle that will
dispense with the necessity of allowing it to slip through the hand at every turn,
or in the case of a turnscrew for example, of taking it out of the screwhead as is
usually the case.
The handle, which is preferably of the form used on gimblets, or T shaped, may
be of wood or other material, and enlarged in the centre where it is bored
through to receive a metallic tubular lining, say for example of half an inch in
diameter, and which is firmly fixed in the handle.
Within the tube I place two similarly formed pieces of metal, say steel, which
when in position, close the tube at each end but leave a central aperture between
them to receive the shank or tang of the implement, the aperture by preference
being oblong to receive a flat shank or tang.
These two pieces when in position practically form one piece, and are so con-
structed that they can easily rotate together in the tube.
In each piece there is a recess open to the tube which encircles them, and which
forms an inclined plane, and in each recess I place a roller, and preferably a spring
to press lightly against the roller and towards the rise of the incline. The before-
mentioned pieces may be retained in the tube by end plates or any suitable means,
and although I prefer to use two pieces as being most convenient, I do not confine
myself to this number.
When the handle is turned in one direction the pieces which form the socket for
the implement are gripped by the rollers and turn the implement, but when turned
in the opposite direction they are released and the handle alone is turned.
If the contrary action is required, the handle is reversed, and the other end of
the socket is placed upon the shank of the implement.
Dated the 3rd day of February 1893.

COMPLETE SPECIFICATION.
Improvements in Handles for Turnscrews, Gimblets, and other like
Implements and Purposes.
I, ROBERT FRANCIS DRURY of George Street, Sheffield in the County of
York Patent Agent, 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 which is a communication from abroad by Charles Warn, of
Stockholm, Sweden, relates to an improved handle for turnscrews and other imple-
ments which are turned by the hand, the object being to provide a handle that
dispenses with the necessity of allowing the handle to slip through the hand at
every turn, or in the case of a turnscrew for example, it prevents the blade being
disengaged from the head of the screw as is usually the case.

Fig. 5, gripping roller.
The bandle A, which is preferably of the form used for gimblets, may be of
wood or other material, and is enlarged in the centre, where it is bored through to
receive a metallic tubular lining B, say for example half an inch in diameter, and
which is firmly fixed in the handle A.
Within-the-tube-B,-I-place-two-similarly-formed-pieces-of-metal-or-socket-
plates C, see Fig. 3, preferably made of steel, which when in position as shown in
Fig. 2, close the tube B, at each end but leave a central socket or opening D,
between them to receive the shank or tang of the screwdriver E, or other like
implement, the aperture D, by preference being oblong to receive a flat shank
or tang.
These two pieces C, when in position practically form one piece, and are so
constructed that they can easily rotate together in the tube B.
In each piece or plate there is a recess or space F, open to the tube B, whi
encircles them, and in which space I place a roller G, preferably of the sa
length as the plate C, or thereabouts, and which is prevented moving or getting
out of place longitudinally by the returned ends H, of the plates C.
A spring may if found desirable be placed to press the roller towards the
narrowing end of the space F.
A small bent up piece I, of the plate C. prevents the roller going too far back
to act promptly.
The plates C, when placed in position with the rollers may be secured in the
tube B, by turning over the ends of the tubes slightly with a burnisher, or by
other means.
When the blade J, is in position and the handle is turned in one direction, the
pieces C which form the socket for the blade, are gripped by the action of the
rollers G, endeavouring to get into the narrow end of the spaces F, and binding
against the tube B, but when turned in the opposite direction the rollers are
released and the socket remains stationary while the handle A, alone is turned.
If it is required to act in the contrary direction it is only necessary to reverse
the handle, and place the opposite end of the socket upon the shank or tang of the
blade J.
Having now particularly described and ascertained the nature of my said
communicated invention, and in what manner the same is or may be carried into
practice I declare that what I claim is :―
An improved handle for turnscrews, gimblets and other like implements and
purposes, constructed substantially as herein before described, and with reference to
the drawings.
