An Improved Tube for Colours.
I, CHARLES JOHANNES PALMIE, of Findlingstrasse, 31/2, Munich, in the Empire
of Germany, Artist, do hereby declare the nature of this invention to be as
follows:-
or less
In the hitherto used metal tubes for colours the quality of the colours suffers
from the oxydation of the metal the colours, which are kept in tin tubes must
receive an addition of wax, paraffin, or tallow, because otherwise they deposit.
Then when the real colour-stuff is deposited in the tube and more
free from the oil (or inversely), it is impossible to mix the same again in the tube
by stirring and shaking. On the other side the colour deposit, that is the real
colour, can no more be pressed out of the tin tube, whilst the contents pressed
out of the tube contains much too little colour-stuff and is unfit for painting.
The said additions effect however an exceedingly injurious influence on the
quality of the colours, as they injure their shining power, and they dry in a
broken manner.
This invention relates to a colour receptacle which avoids all these incon-
veniences.
This receptacle or tube is not of metal (thus oxydation is avoided) but consists
of a bag of animal bladder, rubber, oilcloth, or any other appropriate stuff. The
same being provided with a closing device, which is made of celluloid, glass, gutta-
percha, or other suitable non-oxydating material.
The closing device consists conveniently of a socket with a screwed cap. On
the outside the socket is provided with a groove of corresponding width, in which
the bladder is fixed by means of a strong thread, string, or wire. Of course the
fastening of the bladder on the closing device as well as the construction of the
closing device can also be varied.
The colours packed in these bag-tubes require no addition for preventing the
deposit and are therefore maintained in their quality and shining power.
All good solid colours produced in pure oils deposit and are to be recognised
thereby.
When this depositing has taken place in the bag-tube, one can effect the most
thorough mixing in a few moments by pressing several times the bag with the
hand.

I, CHARLES JOHANNES PALMIÉ, of Findlingstrasse, 31/2, Munich, in the Empire
of Germany, Artist, 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:-
In the hitherto used metal tubes for colours the quality of the colours suffers
from the oxydation of the metal, the colours, which are kept in tin tubes must
receive an addition of wax, paraffin, or tallow, because otherwise they deposit.
Then when the real colouring matter becomes deposited in the tube and more or
less free from the oil or other medium (or inversely), it is impossible to properly mix
the same again in the tube by stirring and shaking, and the colour deposit, that
is the real colouring matter, cannot be pressed out of the tube, whilst the matter
pressed out of the tube contains much too little of the colouring matter and is
consequently unfit for use.
The said additions effect however an exceedingly injurious influence on the
quality of the colours, as they injure their shining power, and they cause them
to dry in a broken manner.
This invention relates to a colour receptacle which avoids all these incon-
veniences.
The annexed drawing shows the improved tube, and in which Fig. 1 is a section
of the closed tube. Fig. 2 is an elevation of the same, and Fig. 3 illustrates
the closing device.
This receptacle or tube is not of metal (thus oxydation is avoided), but consists
of a bag a of animal bladder, rubber, oilcloth or any other appropriate stuff. The
same being provided with a closing device, which is made of celluloid, glass, gutta-
percha, or other suitable non-oxydating material.
The closing device consists conveniently of a socket 6 with a screwed cap c.
On the outside the socket is provided with a groove in which the bladder a
together with the label denoting the contained colour a¹ is fixed by means of a
strong thread, string or wire d. Of course the fastening of the bladder on the
closing device as well as the construction of the closing device can also be varied.
The colours packed in these bag tubes require no addition for preventing
deposit and are therefore maintained in their quality and shining power.
All good solid colours produced in pure oils deposit, and are to be recognised
thereby.
When this depositing has taken place in the bag-tube, one can effect the most
thorough mixing in a few moments by pressing several times the bag with the
hand.
Distemper and all water colours, which are kept in these bag tubes, can be put
into water for the purpose of preserving them and can be kept in this manner
for years.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. An improved tube or receptacle for colours in which a socket is provided with
an external annular groove for the purpose of receiving the free end or ends of
a flexible bag or bladder which is secured therein by means of wires or other suit-
able devices, substantially as and for the purpose described.

ible bag or bladder a with a closing device bc substantially as and for the purpose
described.
