page_text: I ERNST HEINRICH SCHMIDT of 12ª Long Lane in the city of London, Pencil
Manufacturer do hereby declare the nature of this invention to be as follows:-
This invention relates to further improvements on the invention for which
I applied for Letters Patent on the 7th April 1885 N° 4,307 the present improve-
ments having reference to the self supplying and self propelling pencil cases
described in the specification of the said foriner invention.
In carrying out my present improvements which have for object to simplify the
construction and improve the action of the said pencil cases, I construct the pencil
case of an outer case and push piece an inuer or compressing and guide tube, a lead
receiving tube with nozzle, and spring clips or jaws; the inner or compressing tube
is provided with slots into which the spring clips or jaws pass and slide longi-
tudinally when in their open position and the jaws are compressed by the inner
tube by a movement of rotation; the inner tube is provided with a guide slot with
suitable recesses for repelling and propelling the lead receiving tube by means of a
pin on the latter which also works in a suitable slot in the push piece; the guide
tube is provided with suitable means for giving a rotating and longitudinal move-
ment to it, the supply of leads is inserted through the push piece so as to be free to
be automatically fed forward.
When it is required to open the pencil case the same is held point downwards
and the push piece being pressed inwards it will cause the lead receiving tube by.
means of its pin to rotate and thereby release the spring jaws which expand and.
fall a certain distance whereupon the lead receiving tube will also fall and protrude
a certain distance; upon pressure being removed from the push piece its spring
will force it back and will again cause the lead receiving tube to rotate until the
spring clips or jaws are compressed so as to grip or fix the lead whilst the lead
receiving tube is pulled back a certain distance thereby uncovering or propelling
the lead. When the pencil case is inverted and the push piece is operated to close
the same the spring clips are expanded and are free to fall with the lead receiving
tube a certain distance and on pressure being removed from the push piece the
spring jaws will again be compressed and will grip or fix the lead and the lead
receiving tube will be pushed forward a certain distance over the lead,

page_text: I sometimes form or fix the spring jaws on the inner case or tube and compress
them by means of the push piece the said jaws working through openings in the
lead receiving tube.
I can also protrude the nozzle of the lead receiving tube by forming a suitable
slot in the push piece so as to allow the same to be pressed inwards to a sufficient
extent to press the nozzle outwards.
It will be obvious that instead of compressing the spring jaws by a rotating
movement a like effect could be produced by a longitudinally sliding movement.
If required to adapt the herein described lead propelling and self supplying
arrangement to what are known as everpointed or artists' pencil cases I dispense
with the recesses in the guide slot through which the pin on the lead receiving
tube works and arrange the push piece in such a manner as to give a longitudinal
motion and thereby slightly propel and slightly withdraw the lead receiving tube
so as to propel or uncover the lead.

I ERNST HEINRICH SCHMIDT, of 12A, Long Lane, in the city of London, Pencil
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:-
This invention relates to further improvements on the invention for which
Letters Patent were granted to me dated the 7th April 1885 N° 4,307, the present
improvements having reference to the self supplying or feeding and self propelling
pencil cases described in the specification of the said former Letters Patent.
The present improvements have for object to simplify the construction and.
improve the action of the said pencil cases and in order to enable the invention to
be fully understood I will describe the same by reference to the accompanying
drawing in which figure 1 is a longitudinal section of a self feeding, self propelling,
repelling and adjusting and self protruding and withdrawing pencil case con-
structed according to my present improvements, the pencil case being shewn
closed.
Figure 2 is a cross section on line I J of figure 1 and figure 3 is a similar view
to figure 2 but shewing the parts in the position they occupy when the pencil
case is being opened; figure 4, is a similar view to figure 1 but shewing the
pencil case opened; figures 5 and 6 are sectional plans of the upper and under
sides respectively of figure 1; figure 7 is a longitudinal section partly in elevation;.

page_text: figures 8 to 11, are views of some of the parts and figures 12 and 13 are views of
some of the parts slightly modified; figure 14 is a longitudinal section of a pencil
case of somewhat similar construction to that shewn in figures 1 to 11; figure 15,
is a cross section on line K, L of figure 14; figure 16 is a horizontal section of
figure 14; figure 17 is a section of part of a pencil case which is a modification
of that shewn in figures 14 to 16; figure 18 is a longitudinal section shewing the
arrangement illustrated in figures 14, 15, and 16 adapted to an artist's or ever
pointed pencil case. Similar letters in all the figures represent similar or corre
sponding parts.
The pencil case shewn in figures 1 to 11 is constructed with an outer case a, and
a push tube b, having slots c and d; e, is an inner or compressing and guide tube
(shewn detached in longitudinal elevation at figure 8), having a slot g, with
recesses h and i, a slot c', with recesses d¹, and e¹, slots or openings fl, and pins q,
which work in the slots d, in the push tube b, which is shewn detached in longi-
tudinal elevation at figure 9. The lead tube j, is shewn detached in longitudinal
elevation at figure 10 and is provided with a slot k, a pin n, and openings g'; the
lead propeller m, (shewn detached in longitudinal elevation at figure 11) is hollow
and terminates in spring clips or jaws h', and carries a pin l, which works through
the slot k, in the lead tube j, and in the slots c¹, in the guide tube e; the clips or
jaws h², project through the openings gl, in the lead tube j, and pass into and slide
longitudinally in the slots or openings f¹, when the parts of the pencil case are
open as hereinafter described; the pin n, on the lead tube j, passes through and
works in the slots g and c, of the tubes e and b respectively; the guide tube e, is
fixed to the collar o, of the pencil case: the spring p, abuts against one end of the
guide tube e, and against a shoulder at the end of the push tube b; the reserve
supply of leads is contained in the push piece b, as shewn in figure 1, the lead
propeller m, is shewn formed with a conical or funnel shaped end serving to guide
the leads from the push tube b, into the lead propeller.
The pencil case being closed as shewn in figures 1, 2, 5, 6 and 7, in order to open
the pencil case it is held point downwards and on the push tube b, being pressed
inwards it will in its rotating movement bring the pin n, on the lead tube j, and
the pin, on the lead propeller m, out of the recesses i, and d¹, of the slots g and c¹,
respectively; at the same time the clips or jaws h¹, will be free to expand (thereby
releasing the lead) and to pass through the openings f¹, in the tube e, as shewn in
figure 3; the lead propeller will then fall a distance equal to the length of the
slot k, in the lead tube j; the lead tube j, together with the lead propeller m, will
then fall so as to protrude the lead tube. Upon pressure being removed from the
push tube b, it will in its backward rotating movement bring tho pins n and l, into
the recesses and e¹, respectively and at the same time the clips or jaws h¹, will be
compressed by the tube e, and be caused to firmly grip the lead; the pins q, on the
guide tube e, then moving in the straight part of the slots d, the end of the slot c.
will come against the pin n, on the lead tube ;, and will pull it back a short
distance thereby uncovering or protruding a corresponding length of lead and the
parts of the pencil case will be in the position shewn in figure 4. If it be required
to protrude or uncover a further length of lead without closing and again opening
the case it is simply necessary (the pencil case being held point downwards) to
again operate the push piece when a similar action of the propelling mechanism
to that hereinbefore described will take place. To close the pencil case it is held
point upwards and the push tube b, being pressed inwards it will bring the pins n
and l, out of their respective recesses h and e¹, and allow the clips or jaws h¹, to
pass into the openings f¹, and expand; the lead propeller m, will then be free to
fall within the lead tube j, as far as the slot k, will allow; the lead tube j, together
with the lead propeller m, will then fall within the case and on pressure being
removed from the push tube b, it will in its backward rotating movement cause
the clips or jaws h', to be compressed by the tube c, and grip the lead whilst the
pins and l, are brought into the recesses i, and e¹, respectively; the pin n, on the
lead tube j, will then be forced forward on the inclined side of the recess i, in the

page_text: slot g, so as to cover or withdraw the lead a certain distance. It will be obvious
that as the leads in the lead tube and lead propeller move forwards and are used
they will be automatically replaced from the reserve supply of leads.
Instead of propelling and repelling the lead tube as just described it will be
obvious that the clips or jaws may be arranged to be propelled and repelled.
In figures 12 and 13 I have shewn a modified construction of lead tube j, and
guide tube e, respectively the lead tube being shewn in longitudinal section and
the guide tube in longitudinal elevation. In this arrangement the spring clips or
jaws h¹, are compressed by the lead tube j, which has an inward swell or shoulder i¹,
for this purpose; the slot g, in which works the pin 1, on the lead propeller m, is
provided at one end with a rectangular recess h, and at the opposito end with an
inclined portion i. In this case I form the push tube b, with two slots c, and in the
slots & the straight portion is dispensed with.
In opening the pencil case and protruding the lead instead of the lead tube
being pulled back as described when referring to figures 1 to 7 it is simply locked
in the recess e, whilst the pin l, on the lead propeller m, is forced forward on the
inclined part of the slot g, whereby the clips or jaws h¹, are caused to grip and
propel the lead a certain distance. In closing the pencil case the pin 7, is forced
back on the inclined part i, of the slot thereby withdrawing the lead and the
lead tube will then be free to fall and the pins and n, will be locked in the
recesses d' and h.
This modification can be arranged so that the lead tube instead of the lead pro-
peller will be propelled and repelled or both can have a backward and forward
inovement communicated to them as also can the lead tube and lead propeller of
the pencil case illustrated in figures 1 to 11.
The jaws h¹, of the lead propeller m of the pencil case shewn in figures 1 to 11
can be provided with elongations extending to the end of the lead tube for the
purpose of gripping short lengths of lead.
In some cases as shewn in figures 14, 15 and 16 I form the spring clips or
jaws h¹, on the guide tube e, and in this case they are compressed by a depression
on the push tube b, as shewn; the clips or jaws h¹, work through slots g¹, and le¹,
in the lead tube and the slot d, in the push tube b, is elongated as shewn at 1,
figure 14. In other respects the construction of the pencil case is substantially
the same as that herein before described and illustrated in figures 1 to 11. Its action
is as follows:
The parts being in the position shewn in the drawing, when the push tube b, is
pressed inwards to open the pencil case it will by its rotating movement bring the
pin n, on the lead tube j, out of the recess i, at the same time allowing the clips or
jaws h¹, to expand in the wider part of the push tube b, to release the lead and
clear the lead tube j, and the pin n, will by the pressure of the end of the slot c,
be pressed forward so as to protrude the lead tube j, a certain distance. Pressure
being removed from the push tube b, the latter in its backward rotating movement
will bring the pin n, into the recess h, at the same time compressing the clips or
jaws h, which will enter the slots k', and grip the lead; as the push tube continues
to move backwards the depression thereon will slide over the clips or jaws whilst
the lower end of the slot c, pulls back the pin n thereby uncovering or protruding
the lead. When closing the pencil case the push piece in its rotating movement
will bring the pin n, out of the recess h, at the same time allowing the jaws to
expand and the lead tube will fall within the case; when the push piece is relieved
from pressure it will bring the pin n, into the recess i, at the same time com-
pressing the clips or jaws which will then pass through the slots g¹, and grip the
lead; the push piece as it continues to move back wards will force forward the
pin n, on the inclined side of the recess i, and will thereby cover or withdraw
the point of the lead.
It will be obvious that the arrangement shewn in figures 12 and 13 for gripping
short lengths of lead can be easily adapted for use in a pencil case such as that

page_text: In order to ensure the withdrawal of short pieces of lead I can make use of an
inner lead tube m³ having slots n¹, as shewn in figure 17 through which pass the
clips or jaws h¹; the lead fits friction wise at the extremity of the lead tube j.
When a pencil case of this construction is operated to open the same in.the
manner described with reference to figures 14 and 16 the inner tube m¹, with the
lead is free to fall until the latter abuts against the contracted end of the lead
tube, and on the lead tube j, being withdrawn, in uncovering the lead its
contracted end will press against the contracted end of the lead, tube m¹, and force
it back so as to protrude the lead a predetermined distance. When closing the
pencil case the clips or jaws h¹, pass through the slots n¹, to grip the lead and when
the lead tube j, is forced forward as herein before described the inner lead tube m¹,
is held fixed by means of the said clips or jaws and in this manner withdraws the
lead within the lead tube j. From the foregoing description it will be seen that
the lead is invariably protruded the same distance by reason of the inner lead
tube m¹, when opening the pencil case, being forced back a shorter or longer
distance according to the length of the lead protruding therefrom.
An inner lead tube such as that just described and shewn at m', in figure 17,
could be arranged to operate in a somewhat similar manner in a pencil case of the
construction hereinbefore described and shewn in figures 1 to 7.
It will be obvious that the backward and forward movement of the lead tube j,
and inner lead tube m³, can be effected by employing a combination of pins and
slots similar to that described when referring to figures 12 and 13.
When adapting the arrangement of pencil case hereinbefore described and shewn
in figures 14 to 16 to an artist's or everpointed pencil case as shewn in figure 18,
I form the guide tube e, with a straight slot g, through which and in the slot c of
the push tube b, works the pin n, on the lead tube j.
When the push tube b, is pressed inwards it will slide over and release the spring
clips or jaws h¹, from the lead and on the end of the slot c pressing against the
pin n, it will carry the lead tube j, forward as far as the slot g, will allow, and on
the pressure being removed the push tube b, in its backward movement will com-
press the clips or jaws h¹, which will grip the lead; the end of the slot c, will then
carry back the pin n, as far as the slot g, will allow, thereby uncovering or
protruding a certain length of lead. In the drawing I have shewn the lead as
fitting frictionwise in the lead tube j, but it will be obvious that I can construct
it so as to contain and automatically feed forward a reserve supply of leads in
the manner shewn in figures 14 and 16.
