page_text: I, BARNET SOLOMON COHEN, of 24 Great Prescot Street, in the County of
Middlesex, Manufacturer, 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 :—
My invention relates to pencil cases or holders of that class in which the lead or
pencil is inserted in a tube, one end. of which is adapted to be compressed or
contracted so that it will grip the lead or pencil and hold the same in any required
position.
Pencil cases or holders of this class, as heretofore constructed, possess the
disadvantage that, when in use, the lead or pencil frequently slips within the case
or holder, thus necessitating considerable delay in readjusting the same.
One object of my invention is to remove this disadvantage. For this purpose
I construct the nozzle of the pencil case in the peculiar manner hereinafter
described, and provide the outer end of the lead-holding tube with inwardly
extending flanges or projections adapted to be pressed into the lead by the nozzle."
Another object of my invention is to provide a pencil-case which is cheaper and
simpler than those hitherto manufactured.
In the accompanying drawing.
Figure 1 is an elevation of a pencil case or holder constructed according to my
invention; and,
Figure 2 is a longitudinal central section of the same.
a is the handle of the pencil case or holder, which is hollow, and is made of
wood or other suitable material; b is the nozzle which is of metal, and is connected
to the said handle by means of screw-threads for a purpose hereinafter described.
c is the lead-holding tube, which is inserted into the handle a, and which is
provided, at its outer end, with two or more cuts or slits c¹, so that this end is
divided to form prongs or fingers c³.
d is the lead or pencil which is located in the tube o, and which is held, with its
point projecting through the nozzle, by pressing the fingers c³ into contact with the
pencil by means of the said nozzle as hereinafter described.
To enable the nozzle to be moved longitudinally upon the handle, for the purpose
of gripping or releasing the lead or pencil, I provide the said nozzle with an
internal screw-thread e, which fits an external screw-thread ƒ formed on the metal

page_text: collar or sleeve g attached to the handle a, so that, by rotating the nozzle relatively
to the handle, the said nozzle can be moved in one or other direction as desired.
I prefer to construct the screw-threads with a very coarse pitch, as shown in the
drawing, so that a slight rotary movement of the nozzle will move it longitudinally
a sufficient distance to cause the fingers c³ to grasp or release the pencil. These
threads are preferably formed, as shown, by indenting or stamping the metal. The
nozzle is moreover milled, as at e¹, to facilitate the rotation of the same.
To prevent the lead from slipping into the case or holder when in use, I make the
outer end of the nozzle tapering or conical, as shown at h. With a nozzle of this
construction, the fingers care acted upon much more forcibly to press them against
the lead than with a nozzle which is semispherical or curved internally at its outer
end, as in pencils of this class heretofore constructed, because my improved nozzle
offers less resistance than those heretofore constructed to the longitudinal movement
of the nozzle and the action produced by this movement is more like that of a
wedge.
To further ensure the prevention of the slipping of the pencil, I bend the free
ends of the fingers o' of the tube c slightly inwards, or provide them, with inwardly
extending flanges or projections i as shown in Figure 2. When the nozzle is
screwed down so that the tube c is contracted, the fingers cut slightly into the lead,
thereby securely holding the same and preventing its displacement.
Having now particularly described and' ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
First. A pencil case or holder the nozzle of which is made with a conical or taper
end, as, and for the purpose, described.
Second. The provision of inwardly extending flanges or projections upon the
fingers of the lead-holding tube, as, and for the purpose, specified.
Third. The improved pencil case or holder constructed substantially as described
with reference to the accompanying drawing.
