page_text: I, GUSTAV SCHWANHALSSER, of Nuremberg, Germany, Manufacturer, do hereby
declare the nature of this invention and 14 what manner the same 1s to be
performed, to be particularly described and ascertained in and by the following
statement
-
My invention relates to improvements in pencil holders-the object of my improve-
ments are, that on slightly pressing the head of the pencil holder, the lead contained
therein is forced out and when the pressure is released the lead is fastened in its
position, but if a somewhat greater pressure is put upon the end the lead is left
free from its grippers and if the pencil case be held up with the point downward
the lead will fall out
In order to make my invention clear
I refer to the accompanying drawings which form part of this application and in
which similar letters denote similar parts throughout the different figuies
Fig 1 shows a section of my improved pencil holder, without lead
Fig 2 shows a cross section of the same through the line a ẞ fig 1
Fig 2, 3 and 4 are sectional views showing the pencil holder with lead
Fig 5 and 6 are detail views of parts of the holder
In the outside case A, which may be made from wood metal or any other suitable
material, are the three tubes a b and c The tubes a & 6 carries the transporting
mechanism for the lead, which consists of the spring claws e e which are either part
of the tube a or fastened to it, the number of the claws e e can be two or more, fig 1*
shows three and fig 2 two and the spring h on the tube b For clearness in the
drawings, in fig 1 to 4 the claw e is placed opposite to the transporting spring h, so
that the method of operation can be clearly explained
The tube a slides over the tube b and the amount that it slides is governed by the
collar on b The tube a is provided on its outside with a ring 9 which when the
tube is moved forward by the ring on the tube b, as seen in fig 3, coming against
the same abuts against the ring fitted to the inside of the outer case A and thus
prevents the tube a from further movement
The tube b is provided at its top end with three or more slits and provided with a
spring which can either be of the same piece as the tube 6 or riveted or soldered on
to the same
The tube b 18
The claws ee of the tube a pass through the slits mentioned
further provided with the two collars and, the collar 7 rests against the ring m
of the part A' of the outside case, on the tube b between the collar and
the ring m is a spiral spring f coiled, which draws the tube 6 into the case A

page_text: In the tube b is a second tube c in which the lend & fits, this tube c is joined to the
pressing cap k by the pin n, between the collar and the cap is a spiral spring f¹ on
the tube b The spring is stronger than the spring The end of the tube bis
provided with the slitsss through which the pin n passes, the pin n can move the
length of the slits ss when the cap is pressed being fastened to the same
The working of the above described pencil case is as follows
h
If the lead d is fastoned in the holder A as in figure 2 by means of the claws e e
and the cap slightly prossed so is the weaker spring compressed and the tube band
the tube a which fits lightly over b shoved from out the holder A and the claws e e made
to lose their grip of the lead (fig 3) and the spring 1 pressing on the lead d carries
it forward with tube b, when the pressure on the cap is 1eleased, the tube 6 is
pressed back again by the action of the spring f, and the claws e e pressed against
the lead d and holds the lead d fast, by repeated pressing of the cap k can the lead d
be transported from out of the holder by the action of the spring & claws e e being
fitted on the different tubes a & b
The lead d is prevented from falling either out of the case or back into the same, by
the spring h, when the claws e e release their grip of the lead
When a greater pressure is brought to bear on the cap k so that both the springs f
and f¹ are compressed, and the tube c forced forward in the tube 6 fig 4 and against
the slits & s
The tube e presses against the spring h and so leaves the lead d free and
as the lead d is no longer held fast in the case A so can the same be let fall out of the
case A or into the same at will
The above described pencil holder possesses all the good qualities that is desired in a
pencil holder in which the lead can be adjusted at pleasure
Fig 7 7, 8 and 9 show modifications of the pencil holder that instead of the separate
spring for holding the lead fast in the tube, the cap b is slotted and so forms a spring
grip for the lead
The cap of b is provided with the projections wgunst which the end of the tube c
presses and opens the cap (fig 9) by which the lead can fill out or in of the tube c the
same as before described
Having now puticularly described and ascertained the nature of my sud Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim 18
1) In pencil holders the outer case A containing the three inner tubes a, b and c
in combination with the spiral springs fƒ¹, spring and claws e e for the purpose as
described
2) In pencil holders the outer case A containing the three-inner_tubes a,b, and c_in_
combination with the slotted cap of the tube 6 with the projections w and claws e e
the purpose as described
e for
3) In pencil holders the tube a provided with two or more claws ee and the ring o̟
sliding over the tube 6 which is provided with the spring h at its outer end
having the collars, and bearing the spiral springs for the purpose as
described
k
4) In pencil holders the cap / provided with the pin n fitting in the slits 5 5 in
combination with the tube b and springs ff¹ for the purpose as described
