page_text: I, MORITZ SACHS, of Nürnberg, Germany, Manufacturer, 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 :-
. In the following description of my invention reference will be made to the
annexed drawing.
Figs. 1 and 2 show a pencil-holder with propelling or feed mechanism. The
outer tube a contains the blacklead tube b, fastened at its lower extremity. The
blacklead tube b is furnished with a long slit 61 and two lateral recesses b³. To the
tube b is fixed a small tube c furnished with elastic cheeks c¹, which catch into
the recesses 6°. The tube b contains the blacklead d, over which lies freely the
slide g, with the catch g¹; the latter projects from the tube slit b', and catches into
the screw thread h¹ of the tube h. This tube h is arranged at the tube b, capable
of turning as well (as in pencil holders with so-called English guiding) as of shifting
longitudinally.
It is raised at the projection h2 by the spiral spring i resting on the bent portion a¹
of the tube, acts in raised position (Fig. 1) with its bent extremity h³ on the clipping
cheeks c¹ and projects with its upper end, the tube head h*, from out of the tube a
By pressing on the tube head h (Fig. 2), the slide gg¹ is moved longitudinally with
the tube hh', and thereby the blacklead, released from the clipping cheeks, is fed
forward. When the pressure on the tube-head h* ceases, the blacklead remains in
the forward position, when the holder lies horizontally, while the tube h h¹ with the
slide g g gets back again into the original position (as in Fig. 1). The slide gg
being also adapted to be shifted by turning the tube h h¹, this slide can, with the
varying length of the blacklead, always be put in a position, which allows the
blacklead to be fed forward for use by pressing the tube head h. The blacklead,
of course, can also be fed forward for use by merely turning the tube h.
Figa. 3, 4, 5 and 6 represent likewise a holder with feed mechanism. This device
is equal to that of Figs. 1. and 2, with the only exception, that with the holder
shown by Figs. 3, 4, 5 and 6, the blacklead d is rigidly connected with the slide 9 g¹
and the small tube c, with the clipping cheeks and the tube recesses b', are
dispensed with. Owing to the connection of the black-lead d with the slide g g',
the blacklead d-if only the arrangement shown by Figs. 1 and 2 was applied-
could be propelled by longitudinally displacing the tube h, but not be retained in

page_text: its forward position. For attaining the latter purpose, a stopping and releasing
device is arranged, which as it will be shown, may also be applied to holders with
differently constructed feed-mechanism. The stopping and releasing device consists
(Fig. 3):
1) of the elastic catches k, fixed to the tube a.
2) of the tube or slide-piece m, secured to the tube h and furnished with the
recess m¹.
3) of the ring n arranged so that it may be placed over the sliding piece recess m¹
and shifted along the neck h³ of the tube.
The catches tend to approach each other and press constantly against the
sliding surface m. The ring n projects with its wall thickness, slightly from the
slide piece m and is limited or arrested in its backward motion by the tube
projection he, and in its forward motion by the recessed part m of the slide piece.
By shifting the tube h h¹ with the slide g g¹ and the blacklead d (Fig. 4) longitu-
dinally forward by a pressure on the tube head h*, the catches k get on the recessed
part m¹ of the slide piece and expand, when subsequently the pressure on the tube
head ceases.
Now the blacklead is fit to be used. For placing the blacklead into
its original position, the tube h is again shifted forward as far as the tube head
projection h permits, by again pressing the tube head h (Fig. 5). During this
operation the movable ring n is taken along by the tube projection he, and by this
ring the catches & are pressed laterally away from the slide piece recess m¹. When
the pressure on the tube head h* ceases, the ring n is kept free from the catches k,
until, owing to the sudden recoil or upmotion produced by the spring i, the slide
piece recess m² abuts against the ring n and lifts the same out of the catches k, as
the spiral spring i overcomes the elasticity of the catches k. Thereby the catches k
get again laterally close to the slide piece m, and thereby also the parts hgd
resume the position, shown by Fig. 3. Fig. 6 is a cross section of Fig. 5 along
line A.-B. As also this arrangement permits the tube h h' to turn on the tube b b¹,
the slide g g¹ can also here, when the length of the blacklead changes, be brought
into a position, which allows the blacklead to be shifted forward for use by pressing
the tube h. Moreover here the blacklead can also be fed forward as well as with-
drawn by merely turning the tube h h¹.
The feeding forward and withdrawal of the blacklead can here be effected in any
position of the holder, by pressure as well as by turning. The circumference or
edge of the ring may be round or angular. Likewise the catches may differ in
shape from each other. The screw thread h¹, pressed into the tube h, may be
replaced by a helical spring to be provided in the tube. The arrangement of the
separate parts of the stopping and releasing device may also be different from that
shown by Figs. 3, 4 and 5. Figs. 7, 8, 9 represent such a modification of a holder
with a part h, simply adapted to slide longitudinally, which, as in the holders,
hitherto described, is in connection with a spiral spring i. Here the catches are
fixed to the part hand to expand or separate from each other by their elasticity.
The sliding surface m with the recess m¹, however, is situated on the stationary
tube a, that is to say, they are formed by this very tube, and the movable ring n
may be displaced within the limits m¹ and h (Fig. 7). The arrangement is here
made so, that by displacing the part h (which may carry a pen o, or a blacklead
and such like) the catches k, which press against the sliding surface m, slide on the
latter, until they arrive at the recess m¹, where they spread fast, when the pressure
ceases (Fig. 8).
When the part h is again fed forward, the catches k are pressed together
inwardly (Fig. 9) by the ring n, situated at the limit, and they are held in this
position by the ring n, until the latter is suddenly thrown upward with the
parts kk by the spiral spring i, when the pressure on h* ceases, and is stripped off
when abutting against the recess m³, by the catches k, which thereby again get on
the sliding surface.
-
With holders, in which the movable part h is not turned, the movable part n
need not be ring-shaped. This part may, for instance, if the stopping device is

page_text: arranged as shown by Figs. 3, 4 and 5, consist of two small parts of a ring, con-
nected by a pin, which parts are guided and stopped by a pin, working in a slot of
the neck h of the tube.
In all figures analogous parts are indicated by the same letters.
Having now particularly described and ascertained the nature of this
invention, and in what manner, the same is to be performed, I declare, that what
I claim is in holders for pencils and similar objects
1. The combination of a slotted tube b b', which may or may not have clipping
tongues, or cheeks c', with a screw-threaded sleeve hh¹ adapted to turn around
and slide along the tube, a slide g g¹ and a helical spring i, in order to obtain the
feed motion of the slide with the pencil or other object by longitudinal shifting of
the sleeve h h¹ as well as by turning the same.
2. The combination of a sleeve having elastic catches or holders, with another
sleeve, having a sliding surface m and recess m¹, a piece n, situated above the
recess m¹ and movable longitudinally within certain limits, and a helical spring i,
for the purpose of arresting in the forward position the part / carrying the pencil
or other object, and subsequently releasing the said part by a repeated feed motion,
so as to bring it back into the original position.
