"IMPROVEMENTS IN PENCIL CASES, PENHOLDERS, TOOTHPICKS, AND OTHER
SIMILAR ARTICLES, SUCH IMPROVEMENTS BEING ALSO APPLICABLE TO NECKLETS
AND BRACELETS."
Sealed the 8th September 1877, and dated the 23rd April 1877.
PROVISIONAL SPECIFICATION left by the said Albert Barker at the Office of
the Commissioners of Patents on the 23rd April 1877.
ALBERT BARKER, of New Bond Street, in the County of Middlesex, Silversmith
and Dressing Case Maker. "IMPROVEMENTS IN PENCIL CASES, PENHOLDERS,
TOOTHPICKS, AND OTHER SIMILAR ARTICLES, SUCH IMPROVEMENTS BEING ALSO
APPLICABLE TO NECKLETS AND BRACELETS."
The object of this Invention is to prevent the nozzle or tubular portion, carrying
the lead or other marking material, from moving of itself, and thus becoming
unscrewed, whereby it is often lost. For this purpose, and according to one
arrangement, the tube into which the nozzle or tubular holder is screwed I provide
with a catch or fastener, and on this catch or fastener a pin or stud is so arranged
as to take into one of a series of holes in a flange formed on such nozzle at its end
opposite the pencil point, and just above the ordinary screw portion.
When the parts are screwed together they are kept securely and doubly fastened
as soon as the pin enters any of the holes in the flange, and in order to unscrew or
disengage them the catch or fastener must be depressed, and the pin being with-
drawn from its hole they can then be unscrewed. A spiral spring restores the catch
to position.
In another arrangement the spiral spring is dispensed with, and a V shaped catch
or snap is employed which may be used with or without the ordinary screw on the
nozzle or tubular holder. This snap or catch may be on the flange of the nozzle or
on the nozzle itself, and so contrived as to take into a recess or slot in the innermost
tube, or tube containing the movement or works.
The improvements are also applicable to toothpicks, penholders, crochet needle-
holders, and other similar articles, also for securely fastening necklets and bracelets.

the said Albert Barker in the Great Seal Patent Office on the 22nd October
1877.
ALBERT BARKER, of New Bond Street, in the County of Middlesex, Silversmith
and Dressing Case Maker. "IMPROVEMENTS IN PENCIL CASES, PENHOLDERS,
TOOTHPICKS, AND OTHER SIMILAR ARTICLES, SUCH IMPROVEMENTS BEING ALSO
APPLICABLE TO NECKLETS AND BRACELETS."
The object of this Invention is to prevent the nozzle or tubular portion carrying
the lead or other marking material from moving of itself, and thus becoming
unscrewed, whereby it is often lost. For this purpose, and according to one
arrangement, the tube into which the nozzle or tubular holder is screwed I provide
with a catch or fastening, which is so arranged as to take into one of a series of
holes in a flange formed on the nozzle at its end opposite the pencil point, and just
above the ordinary screw portion.
When the parts are screwed together they are kept securely and doubly fastened
as soon as the pin enters any of the holes in the flange. In order to unscrew or
disengage the parts the catch or fastening is depressed, and the pin being withdrawn
from its hole they can then be unscrewed. A spiral spring restores the catch to
position.
In another arrangement the spiral spring is dispensed with, and a V shaped screw-
threaded catch or snap is employed, which may be used with and form part of the
ordinary screw on the nozzle or tubular holder. This snap or catch may be on the
flange of the nozzle or on the nozzle itself, and so contrived as to take into a recess
or slot in the innermost tube, or tube containing the movement or works.
These arrangements are also applicable to toothpicks, penholders, crochet needle-
holders, and other like articles, also for securely fastening necklets and bracelets.
The accompanying Drawings exemplify what I believe the best means of carrying
my Invention into practical effect.
Figure 1 is an elevation of part of a pencil case to which one of my improved
fastening arrangements is applied; Figure 2 is an elevation partly in section;
Figure 3 is a detached view of the lead nozzle in elevation, and Figure 4 is a plan
of same.
A is the innermost tube, or tube to which the nozzle is secured, and B is the
nozzle; is a flange on the nozzle, having an orifice e contrived in its under side,
and d is the catch or fastening; e is a spiral spring to which the fastening is secured
and which restores it to position after it has been depressed. As soon as the
nozzle B carrying the lead or other marking material is screwed into the tube A the
projecting head or point of the catch or fastening d enters the orifice c, and the
nozzle is immediately securely and doubly locked in its tube, and thus all chance of
its becoming loose and moving of itself is avoided.
In order to unscrew the nozzle the catch or fastening d must be depressed, and
as its head or point leaves the orifice the nozzle is free to be removed by unscrewing
in the ordinary way. For further security the flange on the nozzle may have two,
three, or more orifices.
Figures 5, 6, and 7 refer to a second arrangement or modification, Figure 5 being
a front elevation showing the nozzle secured to the tube A; Figure 6, also an elevation,
but showing the tube A depressed in order to unscrew the nozzle, and Figure 7 a
side view of the nozzle detached in order that the catch or fastening d may be more
clearly seen. The difference between this arrangement and that shewn in the
previous Figures is that the catch or fastening & instead of being on the tube A is
on the nozzle itself, and the innermost tube A has a slot or notch f cut in it, into
which the catch d engages. Here the innermost tube A is divided into two portions
A, A. The portion A is capable of being depressed, as shewn in Figure 6, when
the nozzle is to be unscrewed, so that when the catch or fastening d is disengaged
from the slot or notch f the nozzle is free to be unscrewed. A spiral spring e is
placed between the portions A, A*. The slot f has one of its sides slightly inclined,

page_text: as seen in the Drawings, Figures 5 and 6, in order to permit the catch d to rise and
travel over it once or twice when the nozzle is being screwed into the tube A. As
soon as the screwing is completed the catch is opposite its slot, and the spiral spring e
expands and shoots forward the tube A, and the slot or notch f then embraces the
catch and prevents the nozzle from becoming unscrewed.
Figures 8, 9, and 10 show a third mode of securing the nozzle to its tube. In
this arrangement that portion of the nozzle which is screw-threaded has secured to
it or in a piece with it a screw-threaded portion, forming a V shaped catch or
fastening d. This screw-threaded portion, when in its fastened position lies within
an inclined groove c contrived in the tube A for this purpose, and it is provided
with a knob or stud d* which forms part of the nozzle flange. Figure 8 shows in
section the nozzle in the tube in its fastened position; Figure 9 shows in plan the
inclined groove c; and Figure 10 is a detached view of the nozzle, showing the
Vshaped fastening d in side elevation. When the nozzle is to be screwed into the
tube A the knob of the V catch must be pressed into the slot in the flange, this slot
being formed by cutting a portion of such flange away so as to allow the nozzle to
be screwed into the innermost tube A, and as soon as the flange abuts against the
edge of the tube the knob is released and its V catch enters the inclined groove c
and lies therein, and the parts are prevented from becoming unscrewed by them.
selves. When the nozzle is to be removed to insert a lead or for other purpose, the
knob d must be depressed so as to cause it to quit the inclined groove c and to
enter the slot in the flange, wherein it is kept till the unscrewing be completed.
The above arrangements may also be applied to necklets and bracelets to prevent
their becoming unfastened and lost when in use. Figures 11 and 12, however, show
my second arrangement, seen in Figures 5, 6, and 7, applied to a necklet by way of
example. Figure 11 is an elevation of this fastening in its closed position, and
Figure 12 a section. The dotted lines, seen in Figure 11, show the position that the
concentric tube A would occupy when drawn back to free the catch d from the
slot f, in order to permit the flanged piece B carrying the catch to be unscrewed so
as to unfasten the necklet.
Having now described the nature of the said Invention and in what manner the
same may be performed, I declare that I claim,―
First. Fitting the innermost tube (or tube carrying the nozzle) with a catch, stud,
pin, or fastening contrivance, so arranged as to engage in the nozzle and prevent it
from becoming unscrewed and lost, as herein-before described and shewn.
Second. Forming a recess, slot, recess, or notch in the innerinost tube (or tube to
which the nozzle is secured), which, in this instance, is capable of being depressed,
so as to free a stud, pin, or catch fitted on the nozzle for the purposes herein-before
described.
Third. The construction of the screw-threaded V shaped fastening contrivance,
shewn in Figures 8, 9, and 10, acting in manner as herein described for the purposes
set forth.
Fourth. The application or adaptation to necklets and bracelets of the fastening
contrivances, shown in the Drawings, for more securely fastening such articles and
preventing them from becoming unfastened when in use.
In witness whereof, I, the said Albert Barker, have hereunto set my hand and
seal, this Eighteenth day of October, in the year of our Lord One thousand
night hundred and areamber and
