A New and Improved Tool to be used for a Screw-driver, Paper-knife
and Eraser, a Pen Knife, or a Spatula.
I, JOHN EDWARD EVANS-JACKSON of 45 Holborn Viaduct, London, 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 relates to a multiple tool for various
as a pocket or desk tool.
which
purposes,
may be used
The tool illustrated is intended for use as a screw-driver, paper-knife and eraser,
and a pen knife, and a spatula.
Figure 1 is a plan of the tool closed, as to go in the pocket.
Figure 2 is a plan of the tool with the blade in reverse position from Figure' 1,
and projected from the handle.
Figure 3 is a plan with the blade entirely removed from the handle.
Figure 4 is a longitudinal central section of the tool handle with tool detached:
Figure 5 is a section on the line - Fig. 2.
Figure 6 is an edge view of the tool or blade.
Figure 7 a broken plan of one end of the tool, slightly modified.
A indicates the handle of the tool. This handle is of metal preferably iron or
steel, or other metal possessed of a fair amount of elasticity. The handle is
constructed from a piece of wire, which may be of any of the usual shapes of wire
in cross section. The wire composing the handle is slotted, or grooved as at B,
the slot or groove extending along the side of the wire which forms the inside' of
the completed handle. The grooves may be of unequal depth throughout their
length.
The piece of wire which forms the handle is bent into an ox bow or U form.
The groove then extends along the inside of the limbs of the bow or U, so that
the edges of a tool may enter said slot or groove, one edge being in the groove in
each limb.
The ends of the limbs of the bow are naturally or normally a little closer
together than are these members near the bow, so that there is a tendency to bind
a tool in the handle, but the metal of the handle should be sufficiently elastic to
admit of the longitudinal movement of a tool, when entered in the grooves, with
tolerable ease. The blade C, preferably of steel, is preferably about as long as the
handle, and wide enough so that the edges enter the grooves in the limbs of the
handle, as may be seen in Figures 1, 2, and 5. Either end of the blade or tool
may be turned toward the bow or loop of the handle. The tool or blade shown is
thickest at the end D, which end projects slightly from the handle when the tool is
closed, as in Fig. 1, if the proportions be. about as shown. When so closed the
tool takes up but little space, and can easily be carried in the pocket. Even in
this position the tool may be long enough for use as a screw-driver but preferably
it will be projected about as indicated in dotted lines. The grasp of the fingers on
the handle will hold the handle firmly to the tool, so that the tool will keep its
position during ordinary usage.
The sides of the tool shown are concaved, as shown at c c, and this concaved edge
may be sufficiently sharp to serve as a paper cutter.
The blade or tool, from the concaved portion cc to the end E, is reduced in
thickness, so that such portion of the blade forms a flexible mixing tool or spatula,

functions, as each end is adapted for different uses.
The groove B may be cut continuously in the wire while the wire is in continuous
length, before the pieces which form the handle are cut therefrom, or milled into
the handle after the bending. The ends a a of the handle are by preference neatly
rounded, to give a smooth finish, and both handle and tool may be nickel plated or
otherwise plated, polished or finished.
The groove near the bend of the handle may be reduced as by a slight
compression of the metal, (b, Fig. 4) so that the thick end of the blade will be
prevented from sliding back to the bow, so that the thin end of the tool will be
held in extended position. See Figure 2.
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
I claim is :-
:-
1. The tool handle described, consisting of a bow of elastic metal with a groove
in the proximate faces of each limb.
2. The tool handle of elastic metal, of bow form, having the ends of the limbs
normally closer together than the limbs near the bow or bend, and grooved on their
proximate faces.
3. The tool handle of elastic metal, of bow form, having grooves in the proximate
faces of the limbs, and the tool having its edges in said grooves, combined as
described.
4. The combination with the bowed metallic handle having grooves in the
inner faces of its limbs, of the tool or blade having its edges entering said grooves,
and capable of removal from and reversal in said handle, substantially as described.
5. The bent wire handle having a groove in the faces of its limbs, said grooves
of unequal depth, and the tool or blade of unequal thickness, so that one end
enters said groove more easily than the other, in combination, substantially as
described.
6. The bent wire handle having a groove in the proximate faces of its limbs, and
the blade or tool of a width to enter said groove, and having one end formed as a
screw-driver, substantially as described.
7. The bent wire handle grooved in its limbs, combined with the tool or blade
having one end of reduced thickness and constructed to serve as a spatula, paper
cutter, or eraser, substantially as described.
8. The bent wire handle grooved in its limbs, and the reversible tool, the edges
of the tool adapted to enter the grooves in the handle, one end of the tool formed
as a screw-driver, the other of reduced thickness to serve as a spatula, paper
cutter, etc., all substantially as described.
9. The bowed metallic handle having grooves in the inner faces of its limbs,
said, limbs tending toward each other at the open end by reason of the elasticity of
the metal, combined with the tool having its edges, in the grooves, and longitudinally
movable in said handle, substantially as described.
