SPECIFICATION.
Improvements in Pen and Pencil Cases and similar Holders for
Small Instruments.
I, FREDERICK CHARLES DANVERS of Rose Lea, Castle Bar Road, Ealing, in
the County of Middlesex, Gentleman, do hereby declare the nature of this invention
to be as follows:-
Now my
In the Specification of a former Patent granted to me and being No. 18435 of
the year 1889 I described the construction of cases for pens pencils and other small
instruments with a catch attached to or connected with a spring, such catch acting
against a shoulder or in a groove and holding the pen, pencil or other instrument
fixed when in the case, or projected from the case for use, the release of the catch
being effected by pressure on a knob or part of the case so that when the catch was
thus detached the pen, pencil or other instrument could slide in or out.
present invention has reference to a more convenient construction occupying less
space which is especially advantageous where it may be desired to place more than
one instrument in the same case, but is also applicable when the case is to contain
only one instrument. In this improved construction according to one arrangement
adapted for two instruments say a pen and a pencil, two catches are fixed to
or within the case and a spring with pressure knobs or equivalent to the inner tube,
which is adapted to be capable of lateral movement in relation to the outer case.
With such a construction normally the inner tube is held by the spring so that the
fixed catches prevent longitudinal movement of the instruments in either direction.
By a pressure of either a knob or pusher the inner tube can be so deflected that the
carrier that carries the instruments may move longitudinally so as to project one or
other of the instruments or to return it into the outer case as the case may be the
carrier being provided with suitable recesses or shoulders so as when in either of its
projected positions or within the case if the knob or pusher be released the spring
will move the inner tube into a position in which a catch will retain the carrier
until a knob or pusher is again depressed.
My improved construction may be modified so that one catch will suffice even for
two instruments; or so as to adapt the case for one instrument only.

COMPLETE SPECIFICATION.
Improvements in Pen and Pencil Cases and similar Holders for
Small Instruments.
I, FREDERICK CHARLES DANVERS, of Rose Lea, Castle Bar Road, Ealing, in
the County of Middlesex, Gentleman, 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 :-
In the Specification of a former Patent granted to me and being No. 18435 of
the year 1889 I described the construction of cases for pens pencils and other small
instruments with a catch attached to or connected with a spring, such catch acting
against a shoulder or in a groove and holding the pen, pencil or other instrument
fixed when in the case, or projected from the case for use, the release of the catch
being effected by pressure on a knob or part of the case so that when the catch was
IDO37

page_text: thus detached the pen, pencil or other instrument could slide in or out.
Now my
present invention has reference to a more convenient construction occupying less
space which is especially advantageous where it may be desired to place more than
one instrument in the same case, but is also applicable when the case is to contain
only one instrument. In this improved construction according to one arrangement
adapted for two instruments say a pen and a pencil, two catches are fixed to
or within the case, and a spring with pressure knobs or equivalent to the inner
tube which is adapted to be capable of lateral movement in relation to the outer
case. With such a construction normally the inner tube is held by the spring so
that the fixed catches prevent longitudinal movement of the instruments in either
direction. By a pressure of either a knob or pusher the inner tube can be so
deflected that the carrier that carries the instruments may move longitudinally so
as to project one or other of the instruments or to return it into the outer case as
the case may be, the carrier being provided with suitable recesses or shoulders
so as when in either of its projected positions or within the case if the knob
or pusher be released the spring will move the inner tube into a position in which a
catch will retain the carrier until a knob or pusher is again depressed.
My improved construction may be modified so that one catch will suffice
even for two instruments or so as to adapt the case for one instrument only.
In the accompanying drawings illustrative of my invention two arrangements are
shewn in longitudinal section.
Referring to Fig. 1; A is the outer case; B the inner tube; C the carrier,
which is here shewn as having a pencil at one end and a pen at the other, but any
two instruments, alike or different may be similarly fitted for use.
DD are knobs on the inner tube that project through holes in the wall of the
outer case.
E E are two annular catches fixed within the outer case A, one at a certain
distance from each end. The opening in each of these stops is as large in
diameter or as wide as the interior of the inner tube, so that the carrier can pass
through.
Fare springs whereby the carrier when in its normal position, that is not
projected at either end beyond the corresponding stop E or E' is held with the
shoulders at either end of the carrier in contact with that part of the annular ring
that is shewn at top in Fig. 1 thus preventing longitudinal movement of the carrier.
If now pressure be applied to the knob D that end of the inner tube will be
deflected until it bears against the stop G whereupon the orifice of the annular
catch E and the bore of the inner tube will be in a line with each other. According
to a modification the extent to which the inner tube can be moved laterally may be
determined by a projection on the knob adapted to prevent it from entering the
outer case beyond a certain point. In either case after the knob has been
depressed, if the case be held vertical, or at a suitable angle, and the carrier, with
the pencil or other instrument it carries at its then lower end allowed to fall
forward as far as it will go; then on removal of the pressure from the knob
the spring F will move the inner tube laterally so that the catch E will enter the
slot II and hold the carrier with its said pencil or other instrument fixed in position
for use.
In the same way the instrument at the other end may be similarly
projected by holding the case with that end down and pressing the corresponding
knob. In either case the extent to which the carrier can project is regulated by
the pin L which moves in a slot in the inner tube. The inner tube need not
necessarily be round but may be made square or oval or be otherwise shaped to suit
the form of the instrument to be employed, and the catch would be required, in
some cases, also to be similarly altered in form.
Should it be desired to use only one knob or presser in a double instrument, the
carrier must be made somewhat shorter than the inner tube, as shown in Fig. 2.
Here the outer case has within it a stop M of such a height that when the inner
tube is moved laterally by a pressure on the knob, the pin L working in the slot in
the tube and projecting slightly beyond it, cannot pass the stop M, but when the

page_text: tube is not so deflected it can do so. In order to use one of the instruments it is
only necessary to hold its end downwards before pressing the knob when the
instrument will move forward a little within the inner tube, and the pin will pass
the stop M, and on then pressing the knob the instrument required will be projected
for use, and on the knob being released will be held in position precisely as
described with reference to Fig. 1. Similarly on allowing the instrument to return
again into the tube, the carrier is prevented from sliding back too far by the
projecting pin coming into contact with the stop M, and, on removal of the
pressure from the knob, both instruments are housed by the action of the springs.
This mechanical arrangement is equally applicable to knives or other small
instruments, but requires some small modification of detail to adapt it to their
respective shapes. As will be evident one spring of suitable form might in some
cases be used in lieu of two.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination with the outer case the inner tube and the carrier of catches
such as E E' fixed within the outer case so as to prevent end wise movement of the
inner tube, springs (or spring) adapted to retain the inner tube and its contained
carrier normally in a position in which longitudinal movement of the carrier will be
prevented by the said catches and a knob or presser or knobs or pressers whereby
the inner tube can be moved laterally into a position in which the carrier will be
free to move longitudinally until the pencil or other instrument at its projected end
is in position for use in which it will be retained on the knob or presser being
released by the engagement of the carrier with one of the catches as set forth.
2. My improved case or holder for pens, pencils and other small instruments
constructed, arranged and operating as shown in and described with reference to
Fig. 1, or to Fig. 2 of the drawings annexed.
