I LORENTZ ALBERT GROTH K.G.V. Civil Engineer and Managing Director of
the Universal Inventors and Patentees Financial Company Limited 30 Finsbury
Pavement London E.C. do hereby declare the nature of said invention for "A NEW
OR IMPROVED SAFETY STOPPER a communication to me from abroad by Fridolf
Frson Almquist Engineer and Navy Constructor of Stockholm in the. Kingdom of
Sweden but at present at 100 Finborough Road South Kensington London S.W.
to be as follows:-
This Invention which is intended to be fitted to ink and colour bottles has for
object to keep the bottle closed and thus free from dust and being spilt and at the
same time to supply the liquid in such quantities as required by the pen or brush
in an easy and expeditious manner without removing the cork.
The Invention consists of a fine tube of ebony glass or other suitable material
with a wide mouth at its upper end and a flexible rubber cap open at both ends
one of which clasped round the wide mouth of the tube. The tube is then
passed through a hole in the cork which after having an air channel cut in its side
is replaced in the bottle and the other end of the flexible rubber cap stretched over
the neck of the bottle. Upon pressing the rubber cap with the fingers the air will
pass through the the air channel into the bottle and thus force the liquid up the
tube into the wide mouth from whence it may be taken by the pen or brush, while
upon releasing the cap the liquid will again sink into the bottle.
In order to avoid a change of temperature causing an overflow in the tube a
small hole is provided in the flexible cap for the escape of air, which however must
be closed by the finger when pressing the cap.
The advantages of this invention are:-
1st The liquid cannot be spilt or wasted.
2nd All dust &c is excluded.
3rd No time lost by corking or uncorking.
4th Does not soil the brush or penholdera
5th The liquid can be used direct from the bottle.

Industrial and Financial Agency 30 Finsbury Pavement London EC. do hereby
declare the nature of said invention for A NEW OR IMPROVED SAFETY STOPPER,
a communication to me from abroad by Fridolf Freon Almquist, Engineor and
Navy Constructor of Stockholm in the kingdom of Sweden and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement -
This invention which is intended to be fitted to ink and color bottles has for
object to keep the bottle closed and thus free from dust and being spilt and at the
same time to supply the ink or color in such quantities as required by the pen or
brush in an easy and expeditious manner without removing the cork. Similar
letters of reference indicate similar parts.
Fig. 1. shows the application of this invention to large bottles of color and
Fig. 2. shows in section and elevation its application to small bottles as also details
of the tube, cork, rubber cap etc, in which a fine tube of ebody or glass or other
suitable material c. with a wide mouth O. at its upper end and a flexible rubber
cap B open at both ends one of which is clasped round the wide mouth of the
tube C. The tube is then passed through a hole in the cork E. which after
having an air channel a. cut in its side is replaced in the bottle and the other and
of the flexible rubber cap stretched over the neck of the bottle A
Upon pressing the rubber cap with the fingers the air will pass through the air
channel a into the bottle A and thus force the liquid up the tube o. into the wide
mouth C. from whence it may be taken up by the pen or brush while upon releasing
the flexible cap the liquid will again sink into the bottle.
In order to avoid a change of temperature causing an overflow in the tube and
mouth a small hole b. is provided in the flexible cap for the escape of air which
however must be closed by the finger whon pressing the cap.
Fig. 3. shows the application to wide mouthed shallow inkstands in which case
the form of the cap B. is altered to fit the wide neck the large cork E being
hollowed to receive the spiral spring & which surrounds and supports the pipo Ŏ
which is free to move in the cork when the finger is pressed on the hole b.
The advantages of this invention aro
1st The liquid cannot be spilt or wasted.
2nd Exclusion of dust etc. from the liquid.
8rd No time is lost by corking etc.
4th It does not soil the brush or penholdors...
5th The liquid is used direct from the bottle...

Having now particularly described and ascertained the nature of said inven-
tion and in what manner the same is to be performed I' declare that what
I claim is
* SEGLE
1. The pipe c of glass or other suitable material with wide mouth O. for facili-
tating the use of ink, colors eto as herein-before described and illustrated in the
drawings

page_text: 2. The india rubber cap B for compressing and driving the air through the cork
thus causing the liquid to rise in the tube and provided with vent hole bas
herein before described and illustrated in the drawings.
3. The use of the tube C. and cap B for the purpose set forth as herein before
described and illustrated in the drawings.
