AN AUTOMATIC PENCILHOLDER
This invention which is shown on the accompanying drawings, under fig I. to VI.
aims at an exact selfacting adjustment of the pencil in the holder, enabling the
point to protrude only just the distance requisite, preventing the pencil dropping
out of the holder, at causing its perfect retention & extension & at safeguarding it
when not in use.
I therefore claim as my own invention:
1.) The fixing of a moveable cylindrical muff (i.) which adheres to the pencil by
friction, there being at the base of the holder a projection, which limits the foreward
movement & effectuates the entry of the pencil.
2.) The application of the nippers (m.) which act springlike by being rift. &
jagged internally & which are united with the pencil tube by a moveable com-
bination of grooves, which operate independantly on the spring-cylinder (n) that
acts on the oblique surface of the nippers.
By means of this selfacting cylindrical muff (i.) which could be either split or
made as a small spiral, which would slide over the pencil and by the moveability
of the mouthpiece (m) from the holder, the pencil can be fixed at pleasure.
By withdrawing the upper part (h.) which is united with the pencil-case (r.) &
the nippers (m.) towards the cylinder (n.) the pencil is nipped tightly & by pushing
forward the upper part, (h.) the pencil is released (fig. II.) the nippers (m.) project
open & by turning round the holder, the released pencil, returns again into the
holder (fig. III.)
In consequence of the facility, with which the nippers (m.) separate from the.
holder, a new pencil can easily be inserted & by transfering the projection (i.) to

page_text: the interior of the mouthpiece, the pencil can be used until a very small piece only
is left (fig. V.)
The act of writing causes a firm pressure, producing the effect of firmly fixing
the pencil (or coloured ink-pencil) & the jagged interior of the nippers prevents
any dislocation.
therefore claim as my original invention:-
1.) The application of a selfacting cylinder, by the operation of which the pencil
is fixed in its position, caused to move regularly & prevented from dropping out of
the holder.
2.) The application of nippers (m.) which act springlike by being rift & jagged
internally & which are united with the pencil-tube (r.) by a moveable combination
of grooves, which operate independantly on the springlike cylinder (u.) that acts on
the oblique surface of the nippers.

AUTOMATIC PENCIL-HOLDER
" AN
My invention relates to a pencil holder constructed as shewn by the accompanying
drawings, fig. 1 being a longitudinal section and figs. 2 and 3 being respectively an
elevation and a section to an enlarged scale of the nipper. The lead is held
within a tube which is fixed to the head h, this head being fitted to slide a little
longitudinally on the outer case n. To the end of the tube n is screwed the
nipper m which is split along part of its length and has a conical exterior fitting a
conical mouth of the case n. The interior of the nipper m may be serrated or
roughened to give a better hold of the lead l. On the lead is placed a washer i
fitting it somewhat tightly, and for this purpose it is most conveniently made as a
short piece of tube split along its length so as to be sprung on the lead. This
washer has freedom to move a certain distance within the tube. The operation is
as follows. When the head h is pushed down, the nipper m is pushed partly out
of the mouth of the case n and springs a little open so as to release its hold of the
lead which can then be pushed back or, by inverting the pencil, made to drop
back by gravity as far as the washer & permits. On then drawing back the head h,
the nipper is closed, holding the lead which is then protected by being entirely
within the case. When the pencil is to be used, the head his again pushed down
releasing the nipper, and the lead, then dropping as far as permitted by the washer i,
is again grasped by the nipper on drawing back the head h. The recess for the
washer i may be made within the nipper, as shewn in fig. 3 so that the lead may
be used almost to its extreme end.
Having thus described the nature of my invention and in what manner the same
is to be performed, I would have it understood that I make no claim to the holding
of a pencil lead by means of a split conical nipper, but I claim in respect of an
automatic pencil holder :-In combination with the head h, the inner and outer
tubes r and n and nipper m, the spring washer i for limiting the movement of the
lead, substantially as herein described.
In Witness whereof I the said Otto Bussler have hereunto set my hand and
seal this fifteenth day of September in the year of our Lord One thousand eight
hundred and eighty-three.
