Improvements in Magazine Pencil Cases,
1, WALTER BRIERLEY, of Central Chambers, Halifax, in the County of York,
Patent Agent, do hereby declare that I am in possession of an invention for
"IMPROVEMENTS IN MAGAZINE PENCIL CASES" which invention has been communicated
to me from abroad by Georg Lovs, of Königsstrasse, 73 Mürnberg in the Empire of
Germany, Manufacturer, to be particularly described and ascertained in and by the
following statement :-
This invention relates to improvements in magazine pencils cases or holders,
constructed to carry several sticks or pieces of lead which are of different degrees
of hardness, or are of various colour, any one of which pieces of pencil can be used as
required by simply turning round the top of the pencil to a given point, and pressing
the top or end whilst the pencil case is held point downwards.
Such being the nature and object of my invention, the following is a complete
description of same, reference being had to the accompanying drawings in which.
Fig. 1 is a front elevation of the improved pencil case.
Fig. 2 is a sectional elevation of same.
Fig. 3 and 4 shows the mine tube, or lead guide and socket.
Fig. 5 is a detail of a lever.
Fig. 6 is a cross section of the socket o and smaller tube
Fig. 7 is a cross section through the outside socket 1.
Fig. 8 A and B are details.
9.
Fig. 9 is a front elevation of a pencil case having the common screw and for
holding the lead.
The mine-tube or lead guide a is cut out in its lower half (see Figs. 3 and 4)
for the reception of the lever b. The bottom of the mine tube rests in the socket c
and both are held together by the pin d, the latter is placed near the recess e of
the lever band the latter is so fixed that the pivot f is in the slot g of the mine-
tube or lead guide a so that it can only move in a transverse direction to the
longitudinal axis. At the upper end of the cutting of the mine tube there is a
flange having a slot i through which the hooked end of the lever b protrudes when
it is pressed forward together with the mine tube or lead guide a. The band k
which surrounds the mine tube or lead guide a, which latter is free to turn in it,
is secured against longitudinal deplacement, and its circumference has six corru-
gations which fit into six recesses of the corresponding corrugated surface on the
outside socket 1. Six pieces or sticks of pencil or lead of various degrees of
hardness or different coloured pencils rest against the rim m (see Fig. 2) connected
with the mine tube or lead guide a moves within the collar or flange n which is
made light or fixed to the outside socket 7, the collar or flange n has formed in
its edge six notches (see Fig. 8%) with which correspond three studs or pins on
the top of the socket O. Within the socket o and round the socket e lies the spiral
spring p which is compressed by the little tube g which is moveable within the said
socket o and the tube g fits with its corrugated outside into the inside corrugations of
the socket 0 (see Fig. 6). The lower part of the socket c is hollow and has a
slot or saw gate formed in it (see Figs. 3 and 4) so that by expansion it is tightly
pressed against the inside of the tube when a conical shaped button r is fixed
therein.
The action is as follows:-When the button r of the pencil case is pressed and the
said pencil case is held point downwards the pin d in the socket c will push the lever b
to one side by means of the inclined recess e that its hooked end protrudes through
he slot i of the flange h. The slanting or inclined position of the lever 6 causes the
ead that lies before it to enter the mine-tube or lead guide a, the pressure on the
button r being continued, the elastic tongs of the mine tube, or lead guide a are

page_text: pushed out of the outside socket and the lead is allowed to pass through the said
elastic tongs. When the pressure on the bottom relaxes and the spring p expands
the mine tube or lead guide a resumes its former position, and the lead is stopped and
held by the elastic tongs. The lead is withdrawn into its case by pressure on the
bottom the point of the pencil being held upwards and thus causes the lead to fall
back into its destined groove of the corrugation of the outside socket. Numbers or
colours on the cover, n show which pencils are contained in the respective grooves or
corrugations of the outside socket land when a certain number or colour is wanted
for writing or drawing the arrow marked on the socket o is brought to point at the
number or colour by turning the socket o round with the tube g and mine tube or
lead guide a the desired lead will then appear by pressing the button r as described
above. By the notches and the pins or studs formed on the cover n and the socket o
every turn is checked whereby the lead is so placed opposite the lever b that it must
get into the mine tube or lead guide a.
Instead of with elastic tongs as above described the case also be made with an
ordinary screw end wherein a screw holds the released lead (see Fig. 9).
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In magazine pencil cases containing concentrically plain or coloured leads as
described The arrangement of a lever such as b inside the mine tube or lead guide a
operated by the button r and all in combination as and for the purpose herein
described and substantially as illustrated by the annexed drawings.
