COMPLETE SPECIFICATION.
Improvements in and connected with Pencil Holders.
I, OTTO UNGLENK, of Pforzheim, in the Grand Duchy of Baden, German
Empire, Manufacturer, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to an improvement in pencil-holders. The pencil
holders hitherto employed for this purpose offered the inconvenience that during
use the crayon was slowly pushed into the surrounding tube and it was rather
tiresome constantly to be obliged to bring it back again into its original position.
The object of my invention is to provide a mechanism by means of which
pencils of any kind provided or unprovided with metal screw threads may be
employed, in which the crayons effectively can be fixed in their original and in
their end position.
The invention essentially consists of a small cylindrical weighted body provided
with a pin which by rotation of two slotted tubes effectively can be fixed in two
positions, viz., an original and an end-position. This body is hollow in front
and provided with a female screw thread for the purpose of taking the pencil.
The mechanism is surrounded by two or more tubes serving to lengthen the
holder and preventing dirt from entering the mechanism.
My invention will be better understood with reference to the accompanying
drawing, in which :-
Figures 1-5 and 7-8 represent detail views, Figures 6 and 9-11 represent
the pencil holder complete in various outside and sectional views.
Figure 1 in three illustrations represents the form of the first or inner tube A
provided with a slot A¹ and a pin A³. The length of the slot A¹ determines
the run of the crayon; Figure 2 represents in three illustrations a second tube B
sliding upon the first tube A. This tube B is provided with a slot B¹ having at
its extremities two lateral recesses B2 B². At B3 the tube B is notched. The
pin A³ moves within this notch when the tube A and B are rotated in reverse
direction.
Figure 3 represents a ring C which when fixed to the head extremity of the
tube A, secures the outer tube B against displacement.
Figure 4 illustrates a crayon D provided with a screw threaded head D¹.
Figure 5 represents a cylindrical body being hollow at E2 and weighted at E¹.
The hollow part 2 is screw-threaded for the purpose of taking up the crayons.
The weighted piece E is provided with a pin E3 and inserted into the tubes A
and B in such manner, that the pin E³ slides within the slots A¹ and B'. When
now these tubes A and B are rotated in reverse direction, the pin E³ is, when in
an end position, turned into one of the lateral recesses B2 and the pencil screwed
into the hollow part of E is thereby fixed in either the reposing position or in
the position of use.
Figure 6 represents a sectional view of the heretofore described parts when
mounted together, and a transverse section through e f.

page_text: Figure 7 illustrates a tube F for covering the slotted tubes A and B.
This tube F is at its head extremity F1 soldered to the tube A, whereby the
operator is enabled to effect the rotation of the inner tube A by rotating the outer
tube F.
Figure 8 illustrates the cover G of the tubes A and B. This cover is soldered
to the tube B and is provided with rings G₁ and Ga owing to which the pencil
holder can be attached to a chain.
Figure 9 shows in longitudinal section all parts of the crayon when mounted
together.
Figures 10 & 11 illustrate a pencil holder of similar construction in which the
back part of the tube B at the opposite side of the slot B¹ is provided with a
pin H allowing a tube J provided with a slot J¹ to be moved fore and backwards
thereby lengthening or shortening the pencil holder.
For the purpose of covering the slot J a tube K is soldered to the tube J in
length corresponding to the same. This outer tube K is provided with rings G¹
and G³.
Instead of the cover tube F which in the first construction directly surrounds
the tube a tube N is in this case arranged, fixed to the inner tube A by means
of a ring M. By turning in opposite direction the tubes N and K, the same
result is obtained, as if F and Gor A and B were to be turned. In both con-
structions the pin E is pushed in one of the recesses B2 and thereby the pencil
fixed.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
In a pencil holder, the combination of a weighted cylindrical body E carrying
a guide-pin E3, said body E sliding within a slotted tube A, and of a slotted
tube B surrounding the inner tube A and being provided with lateral recesses B²
for the guide pin E³ to enter for the purpose of fixing the crayon in its end
positions, when both of the tubes are turned in opposite direction, substantially
as described with reference to the accompanying sheet of drawings.
