1, WILLIAM PHILLIPS THOMPSON Fel. Inst P A. of the Agency for Foreign Patent
Solicitors 6 Lord Street Liverpool in the County of Lancaster, and 323 High
Holborn in the County of Middlesex Civil Engineer, do hereby declare the nature
of the said invention for IMPROVEMENTS IN PENCIL HOLDERS" (A communi-
cation from abroad by Johann Trebentscheck of Donawitz in the Empire of
Austria, Teacher) and in what manner the same 18 to be performed, to be
particularly described and ascertained in and by the following statement
-
A desire has been felt in scholastic circles to have an instrument for school
children which will hold a short slate or lead pencil firmly and allow of its being
fixed into it or taken out in a simple, secure and quick manner
It has been proved that by their using short slate-pencils or lead-pencils children
acquire a bad method of holding the instrument they write with, and many efforts
have been made to remove this evil-One result of these endeavours was the
construction of brass holders which at each end can hold a pencil as with claws,
while two rings that can be pushed up and down compress the claws. But
these brass holders have the disadvantage, that the rings soon loosen their hold
and allow the pencil to slip out, or the rings are lost entirely, and in addition the
rings and claws are troublesome for the fingers. Other pencil-holders which are
also in use have the drawback, that if the pencil is pushed into them rather too
hard either by accident or carelessness it is a difficult thing to get it out again.
The present invention obviates these deficiencies in slate-pencil and lead-pencil
holders by the construction represented in the accompanying design, and renders
the putting in or taking out of the pencil out of the holder as easy as possible,
even for little children, who have pressed it into the holder either thoughtlessly or
intentionally.
The nucleus of the present invention, by which the above mentioned effect is
produced, consists in the application of a propeller, and in the annexed drawings
there are 12 modifications represented Proceeding now to a description of the
separate figures, it must be stated that the lead-pencil or slate-pencil holder
represented in fig 1 consists chiefly of 2 parts, namely of the tube a, which
contains the lead- or slate-pencil a, and of the propeller Similar letters refer to
Bimilar parts throughout the several views
The cylindrical metal tube a is either quite closed or else provided with a slit t
running right along it (fig 1) In the latter case the tube a is made of sheet-
steel in order to render it elastic enough to retain its width in spite of the repeated

In the former case the tube
can be made of common tin, and the front end of it-the insertion end-made in
the shape of a funnel to facilitate the putting in If, however, the tube is made of
sheet-steel, then the insertion end is slit in several places (fig 3).

To make the pencil easily removable from the tube a even when it is firmly
gripped by the latter, and to prevent the children hurting their hands, the inventor
has constructed the propeller b in such a manner, that it projects beyond the back-
end of the tube, by which means this pencil-holder is easy and convenient to
handle even for children of six years of age This forward and backward motion
of the propeller is limited by means of two knobs c c¹, which are made on it
(figs 1-4) and which strike against 2 corresponding notches d of the tube a
the pencil should happen to be so deep in the tube as not to be removable with
the fingers then the part of the propeller projecting beyond the tube is pressed
against the pencil, which causes the latter to fall out of itself If the tube a is
made of sheet-steel and provided-as mentioned above-with a shit t, the knob c of
the propeller b can easily be forced through the notch d of the tube a without
putting the latter out of shape (figs 1-4) In the case of slit tubes an propeller
made of steel-wire can be used, which is put into the tube a before the latter is
finished or rather before it 18 rolled round If the tube is made in one piece,
therefore not provided with a slit running right along it, it is best to use the
propeller represented in fig 5 It consists of the pin c which is provided with a
head-piece and ends in a screw, and is put into the tube a at the insertion end
of the latter and then screwed on to the wooden propeller b, which is inserted into
the tube a at the opposite end By this means the notch d of the tube a, which
limits the motion of the propellor b comes to be situated between the screw-head c
and the ring k
b
The modifications represented in figs 6 and 7 show models of holders made on
the same principle. In ng 6 the motion of the propeller is limited by the chain 2,
in fig 7 by the shit w of the casing a in which the pin of the propeller 6 moves
Fig 8 shows a construction opposed to that of Fig 7 and consisting therein that
the slit wis not made in the casing a but in the propeller b, and the motion of
the latter is limited by the pin 8, which is passed diametrically through a
In fig 9 the motion of the propeller is limited by the notch d made in the tube a
which catches into a corresponding hollow of the propeller Fig 10 shows a pencil-
holder in which the propeller b made of steel-wire is passed through the hole bored
in the wooden handle
In this arrangement the motion of the propeller is limited
by head c and knob m. The construction represented in figs 11 and 12 18 adapted
for conical pencil-holders made of tin The propeller, which in this case must be
conical likewise, can be made of wood, steel or horn.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent I declare that what I claim 18
In pencil bolders of all kinds the application of an or propeller which is made
to slide backwards and forwards in the casing of the pencil-holder, for the purpose
of removing from the latter pencils that have got jammed in, or been broken short
off in it.
