Improvements in Pencil Cases.

strasse, Nuremberg, in the Empire of Germany, Wholesale Stationers.
I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, 118 New Street, Birmingham in
the County of Warwick, and 31 High Holborn in the County of Middlesex,
Civil Engineer, 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 has for its object an improved extensible or pull-out pencil case.
with a so-called "English" or ever point" guide device, and is designed to
effect by the drawing out of a case a lengthening of the holder and simultaneously
a protrusion of the lead out of the hollow point of the holder into a position
ready for use. Means are also provided whereby the lead may be screwed in or
out by turning the pull-out case.
This improved pencil case having the action set forth, is shown in the accom-
panying drawings, in which,
Figure 1 is a longitudinal section with the holder extended;
Figure 2 a longitudinal section when partly shut up;
Figure 3 an elevation partly in section of the pencil case completely closed, and
Figure 4a transverse section on the line ay of Figure 3.
"
The invention will now be described, reference being had to the drawings
Inside the holder a so-called " English" or "ever point guide device is
suitably secured. This latter consists of a tube fixed to the holder or outer
case a and provided longitudinally with a straight guide slot, the said tube b
containing a lead tube c which is adjustable longitudinally therein, the tube c
having for this purpose at its rear end a projection d working in the said
longitudinal slot and projecting through the slot so as to engage in the thread e¹ of
an internal screw formed in a case e which surrounds the tube b. The case e is
made revoluble on the tube without longitudinal movement. By turning the
case e, the projection d (which is guided in a straight line) together with the lead
tube c is pushed forward or backward. In order to effect this movement of the
lead, by drawing out the pull-out case f, the threaded case e carries at its upper end
a stud or pin g which engages in a slot h formed in the pull-out case f. This slot is
of a spiral form in the forward part h¹ of the case but is straight in the rear
part h. The case fitself is guided in a straight line and prevented from falling
out by means of a projection f which engages in a straight slot i formed
longitudinally in a casing k arranged in the holder.

If the pencil case thus formed, which in Figure 1 is shown open ready for use,
is required to be closed into its non-working condition, as shown in Figure 3, the
pull-out case f is pushed into the holder a. By this movement, in consequence of
the pin g engaging in the slot at its spiral end, the threaded case e of the
English or ever point" guide device is first rotated, thereby causing the lead
or pencil to be drawn inwards. On the pull-out case f being pushed further
forward, the pin g slides in the straight part 2 of the guide slot and no movement
of the lead takes place. On drawing out the case f, the movement hereinbefore
described, is repeated in the reverse direction, that is to say, only an extension of

page_text: the holder is first produced, and on the case f being further drawn out, the pencil
or lead is protruded into a position for use. In order to allow of the lead being
moved in or out of the hollow point a¹ independently of the pulling out of the
case so that the period of utility of the lead may be lengthened, the casing k
provided with the guide slot i may be made revoluble in the holder so that the
lead may be moved in or out by directly turning the case which will carry with
it the pin g.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :-
1. In a pencil case, the combination with an "ever point" guide device, of a
pull-out case having a slot partly straight and partly spiral in which slot engages
n stud or pin fixed to the revoluble case of the "ever point" device, whereby on
the pull-out case being moved in or out, the pencil case is shortened or lengthened
and on the movement being continued, the lead is drawn in or protruded from the
hollow point substantially as set forth.
2. A pencil case comprising an "ever point" guide device having a stud or pin
at the rear end of its operating case, a pull-out case having a slot partly straight
and partly spiral, the said case being adapted to slide over the "ever point" device
with its slot engaging with the pin on its rear end, a casing surrounding the "ever
point" device and adapted to receive the pull-out case in its interior, the said
casing having a longitudinal guide slot to receive a projection on the pull-out case
in order to hold the latter against rotation relatively to the casing and to prevent
it falling or being withdrawn entirely out of the casing and a holder having a
hollow point, in combination, substantially as set forth.

3. A pencil case comprising an "ever point" guide device having a stud or pin
at the rear end of its operating case, a pull-out case having a slot partly straight
and partly spiral, the said case being adapted to slide over the "ever point
device with its slot engaging with the pin on its rear end, a casing surrounding the
ever point" device and adapted to receive the pull-out case in its interior, the
said casing having a longitudinal guide slot to receive a projection on the pull-out
case and being revoluble relatively to the holder and a holder having a hollow
point, in combination, substantially as set forth.
