Improvements in Holders or Cases for Receiving a Penoll-lead,
Pen, or for similar Purposes.
We ANDREW LEITCH of Fulwell, Sunderland, Schoolmaster, and GEORGE
THOMAS MORAN of 26 Villiers Street Sunderland in the County of Durham,
Bookbinder 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 :-
The improvements relate to holders or cases for containing and holding a pencil
lead, slate pencil, crayon, pen, compass leg or any other article capable of being
held at any place along its length by a gripper of the nature hereinafter described
and whatever may be its form in cross section, and the object of the invention is
to provide for the convenient adjustment of the said pencil lead or other article in
the holder or case.
We employ a holder or case consisting of two main parts namely an elongated
handle or main portion of convenient shape with a longitudinal interior recess to
hold the pencil lead or equivalent article, and a cap or end piece with a longitudinal
passage way for the said pencil lead or other article, the said cap being adapted to
be fitted on or in or to the aforesaid handle piece. On the one or other of these
two pieces or between them and not affixed to either is a gripper consisting of
a surrounding piece of any convenient resilient material with a passage way for the
pencil lead or equivalent article and slit longitudinally along its whole length and
with a small portion removed so that it may be contracted circularly, or else
provided with more than one slit not extending along its whole length unless it is
fixed to the cap or to the handle, so that the tongues so formed may be
compressed onto the surface of the pencil lead when the latter is in the position
desired.
This compression is the result of movement of the cap on the holder, such as a
sliding or screwing of the cap into, onto, or around the holder; a contrary movement
of the cap releases the gripper from the compression.
The annexed drawings illustrate the improvements. Fig. 1 representing in
longitudinal section the holder A, the gripper piece F in one piece therewith and
forming the end thereof, it being slit as shown in Fig. 2 and tapered on the
outside to be compressed by the corresponding inner face of the cap B, here made
to screw upon the end of the handle A. L represents the pencil-lead or equivalent
article. Fig. 3 shows the same construction with the exception that the gripper
is here formed as a separate piece C from either the handle A or cap B.
Fig. 4 shows the gripper with one longitudinal cut along its whole length.
Fig. 5 shows the same gripper but provided also with three other cuts not
extending the whole length. Fig. 6 shows a similar gripper with four cuts each
extending only partially along the whole length of the gripper. Fig. 8 shows
another construction in which the gripper is made in one piece with the cap or
end piece such as D and the gripper fits into a tapered hole in the handle A, the
thrust of the gripper into the handle not only secures the cap thereto but compresses
the gripper onto the lead or equivalent L. In this modification the gripper may
be tapered and the pit in the handle A in which it fits cylindrical. Fig. 9 shows
one form of combined gripper and cap in which the gripper G is cylindrical
while the passage way for the lead is larger near the rear end at H so as to
afford more elasticity to the gripper and prevent the lead from snapping while
the pressure is being applied. Fig. 10 shows another form in which the gripper G
is tapered but the passage way for the lead of the same diameter throughout to
ensure compression on to the lead. The gripper is shown with two slits extending

page_text: some way also along the cap. In this form the tip may have only one slit down
one side partly or wholly. Either of these two forms may also be made to screw
into the handle A. When the holder or handle A is of wood the ferrule E of
metal should be placed thereon to prevent splitting. Fig. 12 shows the pit in the
handle as made circular in cross section and the cap D with its gripper end made
with flattened sides when the cap is turned in the handle; this construction
prevents distortion of the gripper which otherwise tends to happen if the edges
of the slits therein immediately touch the surface of the pit in which it turns.
Fig. 13 shows the pit in the handle made oval in cross section while the
gripper piece of the cap D is cut away at the side, in this method of cutting
the pit and gripper, a partial turn of the latter is sufficient to fix or unfix
the lead.
The preferable material for the manufacture of the above, and especially of the
gripper piece, is vulcanite or similar composition, but any suitable material of
sufficient strength, elasticity and resilience may be used...
The pencil may be duplicated at other end, or be provided with a penholder.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a holder or case for the purpose set forth, the construction of the parts
consisting of handle, cap, and gripper whereby movement of the cap with regard to
the handle causes a compression of the exterior of the gripper and by the
longitudinal slitting thereof causes its interior to converge on the pencil lead or
other article therein in the manner herein described.
2. The special construction of the gripper whether singly, or as a part of the
handle or cap substantially as described.
3. The combination of holder or handle A with gripper F and cap B substantially
as described with reference to Fig. 1.
4. The combination of holder or handle A having a. pit therein and cap D
having gripper attached thereto the form of the pit and gripper being substantially
as described.
