Improvements in Combined Pen and Pencil Holders and the like.
I, HENRY HARRIS LAKE, of the Firm of Haseltine Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 novel pen and pencil-holder.
It consists in certain details of construction which will be hereinafter more fully
explained with reference to the accompanying drawing, in which
Figure 1 is a longitudinal section taken through the case, showing the parts which
are held in the case.
Figure 2 is an enlarged longitudinal section of the central portion taken at right
angles with Figure 1, and
Figure 3 is a transverse section.
Similar letters of reference indicate corresponding parts in the several figures.
A and B are the two parts of a tubular case which may be made of hard rubber
or other suitable material.
In one end of the tube B is fitted the stock C which carries the pen D. This
stock has an enlarged central flange, and each end is made cylindrical and fits snugly
into the end of the tubular case B, so that when one end is introduced into the
holder the pen projects, in position to be used, and when introduced in the other
position, the pen is reversed and protected within the case, as shown in Figure 1.
The outer end of the part A contains an erasing rubber E, or, if desired, a pencil
may be introduced.
The inner ends of A and B are fitted to slip over the two cylindrical tubular
ends F which project from a central portion G of slightly larger diameter, against
which the ends of A and B abut, so that when the whole is put together, it forms a
holder and handle for the pen or pencil.
From one of the parts F an erasing knife H projects, and from the other a ruling
pen I, and when the parts are put together as shown in Figure 1, the eraser and pen
are concealed within the tubular holders A and B.
Whenever it is desirable to use either the eraser or the ruling pen, the part A
or B which encloses the implement to be used is disengaged, thus leaving the
implement exposed for use.
In order to conveniently disengage these cases, I have shown the following
construction :-
:-
The tubular portion F contains a spiral spring J plainly shown in Figure 3, and
surrounding the shank K of the two implements H and 1. The two are put
together conveniently by making the larger portion K of the shank hollow and
screw-threaded, and the opposite portion K is made of smaller diameter and
threaded to fit into the part K so that when the two are screwed together, the
discs L which surround the bases of the knife and ruling pen respectively, as shown
in Figures 1 and are drawn down against the ends of the part F, thus holding the
whole firmly together.
The part F has. an angular slot as shown at M, at each end, and pins N which
project from the parts K and K extend out through the slots M, and the ends
project sufficiently beyond the circumference of the part F so that they engage
slots O which are made in the adjacent ends of the two parts A and B.

page_text: The operation will then be as follows :—
When either of the ends A or B are removed, the spring J is extended and the
pin N is thrown out until it strikes the disc L. When the part A or B is to be
replaced it is put on so that the slots O fit over the ends of the pin N and by
pushing this outer tube A or B toward the centre the pin is forced to travel down
the longitudinal part of the slot M until the tube A or B abuts against the central
enlarged part G, when a slight turn forces the pin N into the transverse part of
the slot M, as shown in Figure 1. and at the same time a partial screw-thread upon
the end of the part G engages a corresponding one in the end of the part A or B,
and thus locks the two parts together, holding the spring compressed.
Now, if it is desirable to disengage either of the ends A or B for the purpose of
using the eraser or the ruling pen, it is only necessary to press the thumb or finger
upon the part to be removed with a slight twisting motion which will disengage the
pin N from its locking notch, and this releases the spring and allows it to suddenly
extend itself until the pin N is in the position shown at the right end of
Figure 2.
This sudden motion forces the tubular holder B off, clear of the rest of the
implement, and thus leaves the eraser or ruling pen exposed for use, it not being
necessary for the user to employ both hands for the purpose of disengaging the
enclosing tube, which is sometimes a matter of inconvenience where both hands are
employed.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
:-
1st. A pen and pencil holder consisting of the tubular sections A and B having
the outer ends adapted to receive a pen or pencil, a central double ended piece
containing a stock for the eraser and ruling pen which project from its opposite
ends, as shown, and a means for securing the adjacent ends of the two-part holder
upon the opposite ends of said central stock, substantially as herein described.
2nd. A pen and pencil holder consisting of the tubular holders A and B having
the outer ends adapted to receive a reversible pen stock and rubber eraser
respectively, a central stock over which the inner ends of the tubes are adapted to
fit, said stock carrying an eraser and ruling pen at the opposite ends respectively,
so that they are enclosed within the two parts of the pen stock, a spiral spring
contained within the central stock, pius projecting from the shanks of the eraser
and ruling pen respectively, through slots made in the stock, against which pins the
spiral spring acts so as to force them outward and disengage the holders at either
end, substantially as herein described.
3rd. A holder consisting of tubes A and B adapted to receive reversible pen
stock and erasing rubber at their outer ends respectively, a hollow central stock,
into the opposite ends of which the shanks of an eraser and ruling pen are fitted, a
spiral spring surrounding said shanks within the stock, pins N projecting
transversely from said shanks through longitudinal slots M made in the stock so as
to be engaged by slots O in the inner ends of the parts A and B whereby the spring
is compressed when these parts are forced on to the central stock, and a locking
device for holding them in place when they are forced on, substantially as herein
described.
