Improvements in Pencil Holders.
1, WALTER BRIERLEY of Halifax in the County of York, Patent Agent, do hereby
declare that I am in possession of an invention for "IMPROVEMENTS IN PENCIL
HOLDERS" communicated to me do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to pencil holders and consists of an improved construction,
combination and arrangements of parts whereby the pencil can be brought into
position for use through gravitation, held in position for use and returned within its
containing case through gravitation on reversing the case or container.
Such being the nature and object of this my said invention, the following is a
completo discription of same reference being had to the accompanying drawings in
which-
Fig. 1 is an elevation partly in section illustrating pencil constructed according
to this invention.
Fig. 2 is a like elevation inverted.
Ats are slots in the immovable socket d forming the guide for the pin a which is
fastened to the main tube as illustrated in the diagram. The socket g is moveable
on the socket & between the rims e and e and is also provided with a slot and
prevented from turning by the fast pin into the slit t. The mine is made to slide
in the socket d, when closed the pencilholder has the position shewn in Fig. 1 the
pin is in the levor vertical part of the slits while the socket g rests on the
rim e.
In order to cause the pencil to protrude from its socket D the holder is held with
its point downwards which causos the moveable tube b to fall in consequence, of its
weight. The pin a likewise moves down in the slits and enters its lower slanting
parts. The sliding socket y follows of course the motion of the pin a
as the
latter is prevented from turning by the pin i, the pin a having been turned by the
inclined slits s, as the movement of the socket y passes from the upper wide part of
the slitt into the lower and narrower part of the same thereby preventing any rotation
of the pin a.
By the pin a resting on the sloping edge Z on the one hand, and by pin i prevent-
ing rotation and consequently moving back on the other hand, the position of the
pin a, and that of the pencil is fixed so long as the pencil holder is held downwards as
shewn by Fig. 2.
I
To return the pencil within its covering as at Fig. 1 hold it point upwards. The
socket then falls through gravitation and the pin a enters the wide part t¹ of the
slit t.
The latter admits a rotation of the pin which together with the socket b
descends, whereby the position of the parts as illustrated by Fig. 1 is reestablished.
For varying the length of the lead-pencil protruding from the holder any of the
well known devices may be employed.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what I
claim is :-
:-
In a pencil holder the loose sliding mine-tube 6 free to fall through gravitation when
the holder is held point downwards and secured in the one position by the pin a moving
in the slit s the pin a being prevented from revolving and recoiling by the incline
part of the slots and the narrower part of the slit t, while when the pencil-holder

the lead holder bis returned within its casing D all the parts in combination, arranged
and operating in manner herein fully described and substantially as illustrated by
drawings annexed.
