I, OTTO BUSSLER of Nuremberg in the kingdom of Bavaria, German Empire,
Jeweller 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 that class of pencil-holders which are generally known as
cane-pencils" and has for its object to provide means for keeping the pencil rigidly
in its position for use or its working-position once pushed or pressed into it, so that
it cannot slip back into the interior of the holder, which is automatically effectuated
by a catch-spring in combination with a stop-pin that glides under the spring or
tongue forward to the free end of the latter and over the same so that it rests against
the tongue, and means for drawing back or releasing the pencil when desired into its
first place or position of rest, which consists in a projection, that works or glides in
a curved and closed guide-hole of a somewhat triangular shape.
In reference to the drawings, fig. 1 is a sectional view of the holder on line A B in
fig. 7, the pencil being in its position of rest, fig. 2 shows the same sectional view with
the pencil in its working position; fig. 3 illustrates the holder in its position of rest,
in which the lower part of the exterior pipes or tubes is broken away, to give a better
understanding of the invention.
Fig. 4, 5 et 6 are similar views partially in section designating the different
positions of the mechanism which puts the pencil in the position for use or work as
well as in that of rest; fig. 7 shows a section through the pencil-holder on line C D
and fig. 8 shows a section on line E F.
Before proceeding to explain and describe the nature of my invention itself, I find
it necessary for a better and easier understanding of the same, to explain the con-
struction of the holder which is provided with the new contrivances, and which is
shown as an example in the accompanying drawings, in which hn h' is the outside
tube or pipe, having its one end tapered. This tube n is firmly connected with the
tube h and is provided with two circular shoulders n' and n², a triangular guide-hole
and a catch-spring t, the purpose will become clear, when the manner of using
the pencil will be described. Inside of and loosely fitting in the tube n is another
combined tube g g¹ which possesses two projecting pins o o' and a circular shoulder g³

page_text: of which last named tube g is provided with screw-threads g² and inside of the tube gis
situated the tube which is longitudinally slit up and which is combined with the
knob or trigger k. In is arranged the tuber and therein again the stud or pins s
against which the pencil always rests.
This small tube is embracing the lead-pencil and has on its lower end the
projection and rests on the stud s, which also possesses a horizontally projecting
pins. These pins and both glide in the longitudinal opening of the guiding-
tube which carries the thumb-knob or trigger and engage besides that with the
surrounding the guiding-tube 7, having the already mentioned screw-
thread which can be turned against the outside and firmly connected tubes n h¹ by
means of the also named curved guide i being cut out of the tube n.
tube
The combined tube 7 g is placed movably (in the longitudinal direction) within
tube ¹n and is constantly pressed downward in connection with the pencil-guiding-
tube by the spiral-spring f. The spiral-spring presses in front against the
shoulder n of the tube n and in the rear against the shoulder g³ of the tube gland
rests with the latter on the shoulder 2 of the tube n.
By turning the trigger k the lead-pencil will move to the front and the pins s¹ and
and tuber and studs will be turning too, on account of being engaged with the guide-
slit . While this is done, the projecting pins engaging also with the screw-
thread of the movable tube g must necessarily move upward and take the pencil
along.
After having brought the lead-pencil 6 into the position shown in fig. 1 and 3, the
mechanism is put into operation in which the present invention consists and which
will be described and fully explained in the following:
The tube in which the projection o of the tube is gliding, is provided with a
flexible catch-spring or tongue t which is bent to the inward and the guide-hole i in
the tube is getting broader on the top, so that it receives the shape of a
triangle³.
The tube which is, as already told, fitting loosely in the tube possesses the
projection ", the purpose of which it is, to slide under the catch-spring t and to be
fixed and arrested by the same.
By pressing now on the knob or trigger k, which is shown in its position of rest in
fig. 1 and 3 the whole system of tubes, with the exception of the two exterior ones n
and will move to the front and the pin o' will slip forward under the flexible
tongue and on to and over the tip of the same. In the meanwhile the second pin o'
of the tube g³, projecting into the guide i, is moved upward and into the position i, as
shown in fig. 4. In this moment is heard that well-known sound which originates or
is caused by the catching in of a spring; and this moment the trigger k must be
given free to remain in said position fig. 4, which is effectuated by the catch-springt,
that keeps the pin o¹ and by this the whole system of tubes rigidly in the working
position of the pencil-holder. For drawing back the lead-pencil into the holder it is
necessary to first push the trigger k forward into the position fig. 5, in which the pin o
stands in the uppermost corner or angle of the guide-hole ; by this motion the
whole inner system of tubes has moved a little to the right, as is clearly visible in the
drawings fig. 5, and the pin o¹ has necessarily turned also to the right, thereby
gliding sideward away from the tongue i.
After having finished this first step in the operation of drawing in the pencil, the
knob or trigger must be given wholly free and the whole system of tubes will
then move downward into its first position, what is effectuated by the spiral-spring;
and in the same time the pin o glides along the edge 3 of the guide i shown in fig. 6,
whereby the catch-pin o¹ is coming down with the tubes alongside the catch-spring or
tonguet, that is connected with the outer tube n. Thus being brought into the first
position, the projection o¹ cannot come into contact with the tongue t, till it arrives at
the undermost corner or point of the triangular guide i.
It is obvious to say, that the holder can also be used for pens, coloured crayons or
some other implements instead of lead-pencils, and I do not confine myself of applying
my new contrivance or mechanism to that kind or sort of pencil-holders as is shown

page_text: in the accompanying drawings, but it also may be used as well in connection with any
other construction of pencil-holders.
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:
In a holder for lead-pencils, steel-pens, coloured crayons or other implements.
1.) The combination of a guide-hole with two sloping or slanting edges ¹ ♬ª² and 1ª¿ª
and a stop motion t with the elastically secured implement for the purpose of
bringing the implement into its working position as well as back into its position of
rest by a simple forward and backward motion of the implement, operating and
working in the manner, substantially as described.
2.) The combination of a triangular guide i having two slanting sides and 1,
and a stop motion with an interior system of tubes, which are elastically secured
by a spiral-spring fand which system of tubes holds the pencil or implement for the
purpose of adjusting the implement in its position for use or work as well as in that
of rest, by simple moving the same by pressing on a trigger or knob k, and releasing
the latter from the pressure, all operating and working, substantially as set forth.
3.) The combination of the flexible catch-spring or tongue t with a projecting pin o'
for the purpose of adjusting the emplement in its working position, all substantially
as described.
4.) The combination of a triangular closed guide-hole i having two slanting sides or
edges and on the outside casing of the holder with a projecting pino on the
inner system of tubes for the purpose of disengaging a stop motion and drawing in
the implement into its position of rest, working substantially as set forth.
