IMPROVEMENTS IN PENCIL CASES AND HOLDERS FOR CRAYONS AND OTHER ARTICLES
Year: 1885

page_text: COOL ATCCIOS.
I ERNST HEINRICH SCHMIDT of 21 Maxilla Gardens Notting Hill in the county
of Middlesex Pencil Manufacturer do hereby declare the nature of the said inven:
tion for "IMPROVEMENTS IN PENCIL CASES AND HOLDERS FOR CRAYONS AND OTHER
ARTICLES" to be as follows:-
This invention relates to further improvements on the inventions for which
Letters Patent were granted to me dated the 10th April 1884 N° 6237, and for
which I applied for Letters Patent on the 7th April 1885 respectively.
In carrying out my present improvements I form the rack tube and push piece
in one piece and in this case an inclined slot or slots would be provided therein
which would allow of a slight longitudinal movement of the rack tube inde-
pendently of that produced when the same is rotating; the teeth of the rack
moreover are preferably formed in the opposite direction to that described in my
said former application.
Instead of the lead receiving tube being fixed and the rack tube sliding
longitudinally I sometimes arrange the lead receiving tube so that it shall have a
longitudinal movement whilst the rack tube has only a rotating movement.
;
For this purpose the rack tube is provided with slots having an inclined and
two straight portions; the lead receiving tube has a straight slot on one side of
nearly the same length as the herein before described slot in the rack tube; through
the said slots passes a pin on the push piece; the spring in the push piece bears
against one end of the rack tube and the other end of the rack tube abuts against
a stop in the collar of the pencil case.
In this case when the push piece is pressed the pin thereof will rotate the rack
tube and on abutting against one end of the short straight slot in the lead
receiving tube the said pin will push forward the lead receiving tube as far as it
can move in one of the straight parts of the slots in the rack tube, whereby the
pin of the lead propeller will be moved forward the distance of one tooth; on
pressure being removed the rack tube will be rotated in the reverse direction and
the pin of the lead propeller will become fixed in the rack; the pin of the push

and will pull the latter back the distance of the other straight parts of the slots in
the rack tube thereby uncovering or protruding a predetermined length of lead.
In order to prevent the rotation of the push piece it is made polygonal, or a guide
tube can be provided for this purpose.
Or, instead of the rack tube being free to rotate, it can be fixed to the collar or
outer case and in this case the lead receiving tube has a longitudinal as well as a
rotating movement and the inclined slots and the short straight slot are in the
push piece. The spring of the push piece abuts against the rack tube; the guide
pin passes right through the end of the rack tube into the inclined slots.
The lead receiving tube may fit loosely so as to fall by gravity or it may fit
frictionwise.

When the lead receiving tube fits frictionwise the rack tube is fixed to the collar
and case and cannot therefore rotate whilst the lead tube is as hereinbefore.
described so arranged as to allow of a longitudinal and rotating movement.
On pressure being brought to bear on the push piece it will be caused to first
move a short distance forward longitudinally until the guide pin comes against the
diagonal part of the slots, when the push piece will be rotated, thereby rotating
the pin in the straight slot which will cause the lead receiving tube to rotate until
the pin on the lead propeller is brought out of engagement with the teeth of the
rack tube; the upper or outer end of the slot then comes against the pin in the
straight slot whilst the push piece will move longitudinally the distance of one
tooth from another; the lead tube will be pushed forward the same distance and
the pin of the propeller placed before another tooth.
On pressure being removed the push piece in rotating in its backward movement
will rotate the lead tube and bring the pin of the lead propeller into one of the
teeth of the racks; as the lower or inner end of the straight slot now bears against
the guide pin and the push piece has still to recoil the distance of the straight part
of the inclined slot, it follows that the lead receiving tube will be withdrawn
exactly the same distance, and the pin of the lead propeller being fixed, will
uncover a corresponding length of lead.
Where the lead tube is made so as to fall by gravity a pin is provided which
regulates the extent to which it can fall and in this case the pencil case must be
held point downwards when pressure is applied to the push piece.
I sometimes form the rack which is tubular in shape with a tooth or its equiva-
lent so formed as to act upon the lead receiving tube and the lead propelling pin in
such a manner as to withdraw or cover the lead when the pencil case is being
closed this being effected by the said tooth acting on a pin on the lead receiving
tube at the same time that the pin of the lead propeller is operated by one of the
other teeth of the rack tube; when however the pencil case is opened the lead
receiving tube is free to fall out of the case to a certain distance and the lead is
automatically propelled by the pin of the lead propeller engaging with one tooth of
the rack whilst the lead receiving tube is slightly withdrawn so as to uncover the
lead to a predetermined distance by means of a pin on the push piece working in a
slot in the said tube and in the rack tube which is formed with a partly inclined
and partly straight slot similar to that described in the specification of my said
former application.
Instead of the rack tube being arranged to rotate I can also effect a similar object
to that hereinbefore described with a fixed rack tube and a rotating push piece.
If it is required to provide an elongating pencil case I provide an outer case
having a suitable arrangement for locking or fixing the inner tube thereto in the
elongated and closed positions the said tubes falling into their open and closed
positions by gravity. A suitable means of effecting the above purpose as applied to
the construction of the pencil cases herein before described is as follows:
I place the push piece between the lead receiving tube and the rack tube and
connect the same with the outer tube by a pin passing through the push piece;

page_text: when the push piece is pressed inwards it will rotate and cause the lead receiving
tube to rotate until it is free to fall as hereinbefore described and the pin of the
lead receiving tube which will then press against the rack tube will slightly rotate
the inner tube so as to move a projection with which it is provided out of engage-
ment with a corresponding projection on the outer tube it will then be free to
fall by gravity (the pencil case being held point downwards) into its elongated
position; pressure being now removed from the push piece the inner tube will be
turned in the opposite direction and will be secured in position. To close the
pencil case it is held point upwards and the push piece is again operated when the
parts will operate in a similar manner to that described for elongating the pencil
case with the exception that the lead receiving tube and the elongating case will
fall within the outer tube and will be locked in the closed position.
In order to adapt the herein before described elongating arrangement to a pen-
holder knife or other article I form the racks with only two teeth or recesses or I
can provide the holder with projections which engage with projections on the inner
case for the purpose of locking the holder in its open or closed position. An
inclined slot or slots is formed in the push piece instead of partly inclined slots as
described for the elongating pencil case. When the push piece is operated (the case
or holder being held point downwards) the pin or the projection on the holder is
moved out of engagement with its corresponding recess or projection and is free to
fall and the pressure continuing the projection on the inner tube will be rotated
out of engagement with the corresponding projection on the outer tube, and the
inner tube will then fall into its elongated position; pressure being removed from
the push piece the parts will be secured in position in the manner hereinbefore
described.
To close the case or holder it is held point upwards and is operated in a similar
manner to the pencil case hereinbefore described.
When constructing a case or holder which is not intended to be elongated
instead of the projections on the knife or other article and on the outer case I
provide them with corresponding screw threads or their equivalents of the same
angle as the inclined slot in the push piece which extends nearly the whole length
of the case and is formed with a longitudinal slot in which moves a pin on the
knife or other article; the said article is formed with a slot or slots which passes or
pass over the pin of the case working in an inclined slot or slots in the push piece.
By this arrangement to open the case it is held point downwards and the push
piece being pressed inwards the knife will protrude from the case; when the
pressure is removed the push piece will rotate and carry with it the knife or other
article the screw thread on which will thereby be caused to engage with the screw
thread on the case and the knife or other article is by this means fixed in position
for use.
When the push piece is operated to sheath the knife or other article the latter is
automatically unscrewed and the case being held point upwards it will fall into the
other end of the case and its slot or slots will pass over the pin working in the
inclined slot; when the pressure is removed from the push piece the latter in
rotating will jam or lock the knife or other article in its closed position.
Or instead of the screw threads I may employ a rack tube having suitable
recesses or teeth.
When adapting the case last hereinbefore described to hold and automatically
protrude a knife or other article from each end I provide the case with two com-
bined tubular push pieces and rack tubes moving telescope-wise one within the
other and provided with inclined slots, longitudinal slots recesses or teeth and a
spring or springs; each of the said articles is provided with a pin working in the
said longitudinal slots and recesses or teeth, which latter are made of a depth
sufficient to allow of a somewhat extended movement of rotation to avoid unlocking
one article when the opposite article is being operated to open or close the same.
The rotation of the rack tubes and push pieces can be effected as hereinbefore

page_text: described by means of a pin on the outer tube working in the inclined slots or
other suitable means can be employed for this purpose.
A similar effect to that just described can be produced by employing a fixed rack
tube and a moveable push piece or pieces or guide tube or tubes having a longi-
tudinal slot or slots; or a movable rack tube and a fixed guide tube.
In order to reduce the length of the case I sometimes cause the said articles to
slide over or alongside each other; the parts of the case or holder would be
arranged and would operate substantially in the same manner as those of the case
or holder herein before referred to.

page_text: I ERNST HEINRICH SCHMIDT of 21 Maxilla Gardens, Notting Hill, in the county
of Middlesex, 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 inventions for which
Letters Patent were granted to me dated 'the 10th April 1884 and 7th April 1885,
No 6237 and 4307 respectively, the object of the present invention being to
provide improved means for automatically propelling and adjusting the lead in
pencil cases; for automatically protruding and withdrawing the nozzles of pencil
cases or the articles contained in the cases; for automatically feeding the leads in
and for elongating pencil cases.
In order to enable my invention to be fully understood I will describe the same
by reference to the accompanying drawings in which figure 1 represents a longi-

but shewing the lead withdrawn and figure 37 is a detached view of the push tube.
Similar letters in all the figures represent similar parts.
I will first describe my improvements by reference to figures 1 to 4.
a, represents the outer case; b, is a push piece, or tube which is formed with a
longitudinal slot o, and also with a slot of the shape shewn at d; e, is the rack
tube which is provided with teeth f, and with a slot g, which is formed with a
rectangular recess h, at one end and an inclined recess i, at the opposite end; j, is
the tube which holds the lead formed with a slot k, and in which works a pin l, on
the lead propeller m; the lead tube also has a pin n, which works in the slots g,.
and c, in the rack tube and push piece respectively; the rack tube e, is fixed to the
usual collar o, on the outer case a; a spring p, is placed in the push piece b, and
bears against the end of the rack tube e, which is provided with a pin q, working
in the slot d, in the push piece b; r, represents the lead in the tube j.
To make use of a pencil case of this construction the pencil case being closed as
shewn in figure 1, it is held point downwards and the push piece b, is pressed
inwards; the pin q, on the rack tube working in the slot d, will cause the push
piece to partially rotate thereby carrying the pin n, on the lead tube 7, out of the
recess i, in the rack tube and in a line with the slot g, therein and the lead tube j,
will be free to fall the required distance out of the pencil case; when the pressure is
removed from the push piece b, it will be first caused by the recoil of the spring p,
to rotate in the opposite direction thereby moving the pin n, on the lead tube j, into
the recess h, of the slot g; at the same time the pin l, of the lead propeller m, will
enter one of the teeth f, of the rack tube e; as the pin q, travels in the straight
part of the slot d, it will cause the end of the slot c, to bear against the pin n, of
the lead tube j, and the latter will thereby be drawn backwards a certain distance
and will uncover a corresponding length of lead and the parts will be in the
position shewn in figure 4. If it be required to further propel the lead the push
piece should be again pressed inwards and the pin n, will then be free to fall in the
recess h, and the pin 7, on the lead propeller m, in the backward movement of the
push piece will be caused to engage with the next tooth of the rack tube and
the lead tube will be drawn backwards a certain distance as herein before described
and a further length of lead will be uncovered.
To close the pencil case it is held point upwards and the push piece is operated
as herein before described when the pins l, and n, will be moved out of engagement
and the lead tube j, will fall into the case, the pin l, on the lead propeller m, falling
just below the point of one of the teeth; upon pressure being removed from the
push piece the rotating movement of the same will force the pin n, forward on the
inclined side of the slot i, whilst the pin l, is forced backwards by the inclined side
of the rack tooth thereby covering the point of the lead.
Instead of giving a rotating movement to the push piece I can make it to slide
longitudinally; in this case I form the end of the slot c, inclined as shewn in
figure 4 which is a detached elevation of a push tube so constructed.
Instead of employing a fixed rack tube I can make use of a rotating rack tube,
the push piece and lead tube in this case having only a longitudinal movement;
the slots d, would then be in the rack tube and the pin q, on the push piece b.
I can also in place of the slot g, and recesses h and i, form the rack tube with a
tooth having both sides inclined with which tooth a pin on the lead tube f, would

page_text: engage when
the pencil IS стовей In order CO Cover the point or 118 Tena is
herein before described.
In this case I prefer to form a longitudinal slot of suitable length in the lead
tube j, through which slot passes the pin q, the uncovering of the lead being
effected by means of the said pin q, abutting against the end of the slot and being
thereby moved backwards a certain distance.
In the elongating pencil case shewn in figures 5 to 9 the arrangement of parts
for protruding the lead tube and propelling and repelling the lead is similar to that
herein before described when referring to figures 1 to 4; the pencil is provided
with an elongating tube 8, having a pin or projection t, working in a bayonet
slot u, on an extension of the collar o, within the case a; a sliding or telescoping
tube v, shewn in longitudinal elevation at figure 10, is also provided having a
slot w, in which slides the pin n, on the lead tube and a slot x, in and out of which
slides the pin 1, on the lead propeller m; the said tube v, also carries a pin z,
which works in a slot a¹, in the rack tube and also in the slot c, in the push piece;
the rack tube is shewn in longitudinal elevation at figure 11; the elongating tube 8,
is formed with a bayonet slot y, for receiving the pin q, on the case a; the pin q,
extends right through the pencil case and works in two slots d, in the push piece.
shewn in figure 12 which is a longitudinal elevation of the push piece; the push
piece b, has also an open slot 61, in and out of which slides the pin n, on the lead
tube j; shewn in longitudinal elevation in figure 13.
The action is as follows:-
The pencil case being closed as shewn in figures 5, 7 and 9 in order to open the
same it is held point downwards and the push piece b, is operated; the push
piece b, in rotating will release the pins l, and n, from their respective recesses and
will then cause them together with the pin z, to bear against the rack tube so as
to give the latter a slight rotating movement and thereby bring the pin q, out of
the recess of the slot y, in the elongating tube 8; the parts of the pencil case will
then be free to fall by gravity into the elongated position; on pressure being
removed from the push piece b, it will in its backward rotating movement bring
the pin t, into the recess of the slot u, thereby securing the pencil case in its
elongated position; the push piece b, then moving backwards longitudinally the
end of the slot c, will bear against the pin z, and the end of the slot w, on the
tube v, against the pin n, on the lead tube j; the pin l, on the lead propeller m,
having engaged with one of the teeth of the rack e, in the manner hereinbefore
described when referring to figures 1 to 4, the tubes j, and v, will be pulled back-
wards so as to uncover the point of the lead as described and shewn in the said
figures; the parts of the pencil case will then be in the position shewn in figure 8.
To close the pencil case it is held point upwards and the push piece b, being
operated the parts will be unlocked and will be free to assume their closed position,
the pin q, entering the slot y; on pressure being removed from the push piece b,
it will by its backward rotating movement cause the pin q, to be locked in the
recess of the slot y, whilst a backward movement of the lead propeller m,
and a
forward movement of the lead tube j, takes place similar to that described when
referring to figures 1 to 4. It is to be observed that when using a solid lead
propeller as shewn in figures 5 to 8 the lead is not actually withdrawn but a
certain space is produced between the lead and the propeller which is again closed
when the pencil case is opened.
I can in some cases dispense with the use of the sliding or telescoping tube v;
the pin n, on the lead tube j, would then work in the slot c, and the pin l, on the
lead propeller m, in the slot 61, of the push piece b.
When adapting the elongating arrangement shewn in figures 5 to 13 to a holder
for containing a pen, knife or other article I form the rack tube e, with two teeth
or recesses on one or both sides thereof or I can provide the article with a
projection or projections which engage with a projection or projections on the
elongating tube 8, for securing the article in its open or closed position. The

page_text: slots d, on the push piece b, are inclined only; the operation of the parts of the case
will be understood without further description. It will be obvious that the
telescoping tube v, can also be dispensed with in this arrangement.
When constructing a case or holder for a knife (or other article) which case or
holder is not intended to be elongated as shewn in figures 14 to 19 I form the
shank of the knife j, with a screw thread t, of a corresponding angle to the angle
of the inclined slot d, in the push piece b, which extends nearly the whole length
of the case as shewn; figure 19 is a longitudinal elevation of the push piece; in
the longitudinal slots c, in the push piece works the pin n, on the shanks of the
knife in which the slot y, is formed which passes over the pin q, in the case a, the
said pin working in the inclined slots d, in the push piece b; the end of the case a,
is formed with a screw thread u, corresponding with the screw thread t, on the
shank of the knifej; the part of the shank having the screw thread t, is of a
triangular form in cross section as shewn in figures 17 and 18; the part of the
case a, having the screw thread u, is formed with grooves c', corresponding to the
angles of the screw t.
By this arrangement the case being closed as shewn in figures 14 and 15 in order
to protrude the knife blade j, the case is held point downwards; the push piece b,
is pressed inwards and in rotating will release the pin n, from the recesses of the
slots c, in the push piece b, the knife blade j, will then fall and protrude from the
case a, the angles of the screw.t, passing through the grooves c¹, in the screw u;
upon pressure being removed the push piece b, in its backward rotating movement
will carry the pin n, on the knife j, with it and thereby rotate the screw t, and
engage the same with the screw u, and the knife blade j, will be secured in position
for use as shewn in figure 16. When the push piece b, is operated to sheath the
knife j, the screw t, is disengaged from the screw u, and the angles of the screw t,
will be in the position shewn in figure 18 free to pass through the grooves c³, in the
screw u, and the case being held point upwards the knife blade will fall within the
case a, and its slot y, will pass over the pin q; when the pressure is removed from
the push piece b, it will in its backward rotating movement cause the pin n, to be
locked in the recess of the slots c, as shewn in figures 14 and 15.
Instead of forming screw threads on the shank of the knife and in the case
respectively I can arrange the pin n, on the knife j, to be locked in a suitable slot
at the outer end of the case a.
I can also dispense with the recesses in the slots c, and in this case I provide the
slot y, with a recess for securing the pin q; or the slot y, formed as shewn can be
caused by the backward rotating movement of the push piece to be jammed by the
pin q, so as to secure the knife blade in its closed position.
When adapting a case such as that hereinbefore described and shewn in
figures 14 to 19 to hold and automatically protrude two articles such as a pen and
an ordinary lead holder as shewn in figures 20, 21 and 22 I provide the case a,
with two combined tubular push pieces and rack tubes b, and B, moving telescope-
wise one within the other; the tubes b, and B are each provided with longitudinal
slots c, and C and with slots g and G, having recesses "h, i, and H, I; also with
inclined slots d and D through which passes the pin q, on the outer case a;
j, represents the penholder having the pin n, which works in the slots c, and G ;
J, is the lead holder having a similar pin N which works in the slots C and g; the
spring p, for operating the push tube B, bears against the ends of the tube B and
collar o, and the spring P for operating the push tube b, bears against the end of
the tube b, and a shoulder O, on the push tube B.
In order to protrude one of the articles (say for example the lead holder) from
the case a, the parts being in the position shewn in figures 20 and 21, the case is
held with the push tube B downwards and pressure being placed on the other push
tube b, it will rotate and cause the pin N to be rotated until the slots g, and C,
coincide, when the- lead holder J will be free to fall and protrude from the case
į

page_text: the said rotating movement will have carried the pin n, from the position shewn
in figures 20 and 21, to the end of the recess I of the slot G; on pressure being
removed from the push tube b, it will in rotating backwards lock the pin N in the
recess h, of the slot g, thus securing the holder in position for use and bringing the
pin n, again into its normal position as shewn in figure 22.
To sheath the lead holder J, it is held point upwards and the push tube b, being
pressed it will rotate the pin N until it is free to fall and on the push piece being
relieved from pressure it will in its backward rotating movement lock the pin N in
the recess i, of the slot g, the pin n, having meanwhile been operated in a similar
manner to that hereinbefore referred to when describing the operation of pro-
truding the lead holder. In order to protrude and withdraw the penholder j, the
push tube B is pressed inwards and the action of the parts for operating the pen
holder will be similar to that herein before described when referring to the parts
for operating the lead holder.
When constructing the case to operate two articles which are contained within
the case alongside each other-as shewn in figures 23 to 28 I employ only one push
tube (shewn detached in longitudinal elevation at figure 27) which is operated
from either of its ends b, B, and which is formed with two sets of slots c, C, having
recesses I respectively; the push tubes b, B, has also pins q, q, working in the
slots d, in the rack tube e; the rack tube is shewn in figure 28, which represents a
longitudinal elevation of the same; as will be seen it is formed with two sets of
slots g, and G, having recesses h, and H respectively; the shanks of the two
articles (a knife blade J and a button hook j) are by preference formed semicircular
in cross section as shewn in figure 24 and they are provided with pins N and n,
respectively; the pins N work in the slots C and G and the pins n, work in the
slots c and g; the rack tube e, is fixed to the collars O and o, within the case a.
To protrude one of the articles (the knife for example) the parts being in the
position shewn in figures 23 and 25, the end B of the push piece is held down-
wards and the other end b, is pressed inwards and will thereby be rotated and the
recesses I will be moved away from the pins N, when the knife blade will be free to
fall and protrude from the case; the innermost part of the recesses i, meanwhile
will have been brought against the pins n; on the push piece being released it
will in its backward movement lock the pins N in the recesses H of the slots G, at
the same time bringing the recesses i, into their normal position as shewn in
figure 26. To sheath the knife it is held point upwards and on pressure being
applied to the end b, it will in rotating bring the pins N out of the recesses H and
the knife will then fall within the case the pins n, being again brought against the
inner sides of the recesses ; on pressure being removed from the push piece it
will in its backward rotation bring the pins N into the recesses I so as to lock the
knife in its closed position: The operation of the parts when protruding the button
hook will be well understood from the preceding description.
I can adapt the arrangement of case last herein described to contain two articles
placed end to end instead of side by side; in this case I arrange the slots for locking
and unlocking the articles end to end instead of side by side.
In either case I can employ two separate short push tubes each having a pin
which works through a straight slot in the fixed rack tube and in an inclined slot
in a rotating guide tube the rack tube having bayonet slots and the guide tube
having straight slots similar to those shewn in figures 20, 21 and 22. Or the guide
tube can be fixed and the rack tube can rotate. The action will be easily understood
by referring to the description of the case shewn in figures 20, 21 and 22.
When constructing a case of a flat shape for containing and protruding a knife
(or other article) as shewn in figures 29 to 32 I employ a flat shaped push piece b,
(shewn in longitudinal elevation at figure 33) provided with a slot c, in each of its
narrow sides the said slots having inclined parts i, and h, to allow of securing the
knife j, in its open or closed position as hereinafter described; the push piece b, is
also formed with slots d, in which works the pin q, on the case a; the narrow

page_text: sides of the case a, (shewn detached in longitudinal elevation at figure 34) are
provided with longitudinal grooves g, having inclined parts h, and i, at opposite
ends to the similar inclined parts of the slots c, in figure 23; the knife j, is
provided with pins n, which work through the slots c, in the push tube b, and in
the grooves g, in the case a.
The operation is as follows
To open the case the parts being in the position shewn in figures 29 and 31 the
case is held point downwards and the push tube b, being pressed it will move
forward longitudinally until the inclined parts h, and i, of the slots c, and g,
respectively coincide when the pins n, on the knife will be free to fall and allow
the knife to protrude a certain distance; upon pressure being removed from the
push tube b, it will in its backward movement bring the straight parts at the end
of the slots c, over the inclined parts i, of the slots g, thereby fixing or locking the
knife in position for use as shewn in figure 32. In order to sheath the knife the
case is held point upwards and the push tube b, being operated a similar action of
the parts will take place in the reverse direction to that herein before described
and the knife will be locked in its closed position as shewn in figures 29 and 31.
As will be readily understood the case or holder last hereinbefore described and
illustrated in figures 29 to 34 can by employing a double set of slots c, and 9, be
adapted for containing and operating two articles which can be arranged end to
end or alongside each other.
In the pencil case shewn in figures 35 to 37 which illustrate a somewhat similar
arrangement to that hereinbefore described and shewn in figures 1 to 4 adapted to
an Artist's or ever pointed pencil case, a, is the outer case with the usual collar o;
b, is the push tube with a diagonal slot d, and a straight slot c, in which work the
pins n, and q, on the lead tube j, and rack tube e, respectively; o, is the rack tube
with teeth f, and a slot i, and it is also provided with the pin q, which works in
the slot c;
This rack tube is fixed to the collar o, and case a.
j, is the lead tube in which the lead propeller m, with a pin 7, is free to fall by
gravity and it is also provided with a pin n, which works in the slots i, and d, of
the rack tube e, and push tube b, respectively.
The action is as follows:-
The pencil case is held point downwards and pressure being applied to the push
tube b, the lead tube j, will be carried forward by means of its pin n, until the
latter comes against the lower inclined part of the slot i, when the lead tube j, will
be rotated thereby releasing the pin l, on the lead propeller m, which is then free
to fall until the lead comes up against the conical or narrowed point of the lead
tube; on pressure being removed the pin n, will cause the lead tube j, to rotate
by coming against the upper inclined part of the slot i, thereby fixing the pin 7, on
the lead propeller m, in one of the teeth f and the pin n, moving back the
remaining distance of the slot i, the lead will be propelled or uncovered a
corresponding distance as illustrated at figure 35. The shape of the teeth f, as
shewn at figure 35 would be preferable. To withdraw the lead within, or cover it
by, the lead tube j, the pencil case is held point upwards and pressure is applied to
the push tube b, when the lead tube j, will be pushed forward and as the lead is
fixed by means of the pin l, on the lead propeller m, it will be withdrawn within
the lead tubej, and the tube j then being rotated as hereinbefore described the
pin 7, is brought out of engagement with the teeth f, and is free to fall by gravity.
On the backward movement of the push tube b, the pin l, will be fixed in the
uppermost tooth of the rack tube e, and the lead will thus be entirely withdrawn
within the lead tube j, as illustrated at figure 36. The slots i, d and c, may
obviously be slightly modified as to their shape and combination to obtain
substantially the same result.
Or the lead tube may be elongated to protrude through the upper end of
the case a, in which case the push tube b, with its slots and the pin q, may be
dispensed with.
