THOMAS FOXALL of Drummond Street Euston Square in the County of

"
In colour boxes as at present constructed rectangular compartments or spaces for
the reception of the tubes of colour or paint are formed by means of simple vertical.
partitions of wood or metal.
These compartments are made considerably wider and deeper than the tubes.
which they are intended to receive, so as to allow of the easy removal of the tubes;
and a disagreeable rattling is thereby produced when the box is carried or moved
about.
Moreover should the tubes leak at all, at either end, the bottom of the box
becomes dirty, and the tubes become smeared with paint and unpleasant to handle.
Now the object of the present improvements is to remedy these defects, and to
this end the invention consists in providing and adapting within the colour box a
series of half round spaces formed conveniently by a suitably corrugated metallic_
plate, mounted on a platform or bed at a suitable distance from the bottom of the.
box and constituting a raised rack; the half round spaces or corrugations of this
raised rack being of a gauge corresponding to the diameter of the tubes, they are
to contain, so that the tubes will lie closely within the parallel grooves or semi-
cylindrical spaces of the said raised rack, without the possibility of lateral
vibration.
The rack is narrower than the length of the tubes it is intended to receive, and
the tubes will therefore project beyond its edge at either end, and be kept from
contact with the bottom of the box. Any paint therefore which may loak out of
the tubes, will not soil the rack or the bodies of the tubes, but will fall clear of the

By this improved construction of box the colour tubes are kept well in sight and
clean and smooth to the touch. They can be easily taken out or replaced, are not
liable to shake about, and consequently do not require any packing to keep them

THOMAS FOXALL of Drummond Street, Euston Square in the County of
Middlesex, Japanner "IMPROVEMENTS IN THE MANUFACTURE OF COLOUR BOXES "
In colour boxes as at present constructed rectangular compartments or spaces for
the reception of the tubes of color or paint are formed by means of simple vertica!
partitions of wood or metal
-
These compartments are made considerably wider and deeper than the tubes
which they are intended to receive, so as to allow of the easy removal of the tubes.
This looseness of fit causes a disagreeable rattling to be produced when the box is
carried or moved about. Moreover should the tubes leak at all at either end the.
bottom of the box becomes dirty and the tubes become smeared with paint and
unpleasant to handle.
-
The object of the present improvements is to remedy these defects, and to
simplify and cheapen the manufacture of such boxes. To this end the invention
consists in providing and adapting within the color box a series of half round spaces
formed conveniently by a suitably corrugated inetallic plate mounted on a platform
or bed at a suitable distance from the bottom of the box and constituting a raised
rack;
the half round spaces or corrugations of; this raised rack being of a gauge
corresponding to the diameter of the tubes they are to contain so that the tubes
will lie closely within the parallel grooves or semi cylindrical spaces of the said
raised rack without the possibility of lateral vibration or rolling.
The rack is narrower than the length of the tubes it is intended to receive, and
the tubes will therefore project beyond its edge at either end, and be kept from
contact with the bottom of the box. Any paint therefore which may exude from
or leak out of the ends of the tubes will not soil the rack or the bodies of the tubes
but will fall clear of the rack and tubes onto the bottom of the box below..
The tubes are raised by the rack to such a level that they will about touch the.

page_text: underside of the palette, or a tray of colour tubes similarly supported, when in
place.
By this improved construction of box the color tubes aró kept well in sight and
clean and smooth to the touch. They can be easily taken out or replaced, are not
liable to shake about and consequently do not require any packing to keep them
in place
The rack may be made of wood, metal or other suitable material and be suitably
supported; and two or more of such racks may be adapted to one box and be
disposed as may be most convenient
In the accompanying drawing Fig: 1 shews in plan view an oil color box
fitted according to my improved system with a raised rack for holding the tubes
in place.
Fig: 2 is a longitudinal vertical section of the box on the line 1. 2 of Fig: 1,
and Fig: 3 is a transverse vertical section taken on the line 3. 4 of Fig: 1.
In these Figures A is the raised rack consisting of a scries of semi cylindrical
grooves a a a adapted to receive the tubes of colour or paint, B, and hold them so
that they cannot roll from side to side when the box is carried about.
These semicylindrical grooves a a may be formed out of wood or other suitable
substance, but are preferably made by bending or corrugating a piece or pieces of
shoot tin into the form shewn in the detached views Figs: 4, the bent or corrugated
strip a a being mounted on a foundation piece or bed a², also preferably of tin, to
which it is secured by soldering or otherwise, and by which it is. raised about its
own height above the bottom of the box. These raised metallic racks can be made
and fitted within the box with far less trouble and cost than the separate vertical
partitions hitherto used.
As will be seen on reference to Fig: 3 the tubes B are supported at their middle
by the raised rack A, and their ends project beyond the rack and are kept clear of
the bottom of the box C. Thus should any leakage of the color or paint from the
tubes B take place it will not soil the rack A but will fall on the bottom of the
box C beneath. When the box is closed the palette D (see Fig: 2) is so arranged
as to nearly or just touch the tops of the tubes B B so that they are prevented
from rising out of the half round grooves or corrugations a a.
This holding down of the tubes B may also be effected by causing the bottom of
a detachable tray of color tubes to nearly or just touch the tops of the tubes
below it, when in place.
When a colour tube is required for use it can be at once picked out of the rack
by_depressing it at either end, as shewn by the dotted lines in Fig: 3.
By this arrangement the tubes are kept clean and smooth to the touch; they
can be easily seen and removed or replaced when required, and will not roll about
and make a rattling noise when the box is being carried or moved from place to
place.
In Figures 5. 6 and 7 I have shewn a double rack applicable to the holding of
one row of whole tubes or two rows of half tubes of color or paint. Fig: 5 is a
plan view of the box with the lid wide open, Fig: 6 is a longitudinal vertical
section on the line 1. 2 of Fig: 5, and Fig: 7 is a transverse vertical section on
the line 3. 4. of Fig: 5. The same letters of reference indicate corresponding parts
to those previously described. In this case the rack is composed of two parallel
corrugated strips of metal, each raised on a suitable foundation or bed above the
bottom of the box. The width of each strip and also the width of the intervening
space, is such that either half tubes B' B', or whole tubes B B, may be held in
place in the manner already described, that is with their ends clear of the rack and
above the bottom of the box.
The lid of the box is shewn in these figures as stamped out of sheet metal in such
a manner as to leave a clear central space for the colours on the palette when the
latter is put away wet or charged with paint, and to form a narrow margin around
the said space which serves to hold down the palette all round, without the necessity
for soldering in bosses or other pieces of metal for that purpose.

page_text: The width of the bent or corrugated strips used for the raised racks may vary
considerably and I do not limit myself therefore to the proportions shown in the
drawings; what is essential being that the bends or corrugations of the rack shall
be of a shape and breadth to properly support the tubes and hold them against
lateral motion; that the ends of the tubes shall project over the sides of the rack;
and that the said rack shall be raised by a suitable bed or foundation so that the
projecting ends of the tubes are clear of the bottom of the box
Having now set forth the nature of my Invention of "Improvements in the
manufacture of Color Boxes" and explained in what manner the same may be
carried into practical effect I wish it to be understood that I claim :-
First The adaptation to colour boxes of raised rack or racks for the reception
of the colour tubes in the manner and for the purpose above set forth.
Secondly The use in a colour box of a bent or corrugated strip or strips of metal
such as a a each mounted on a raised bed or foundation and adapted to hold the
tubes of colour in the manner and for the purpose described with reference to the
drawings
In witness whereof I the said Thomas Foxall have hereunto set my hand
and seal the eighteenth day of June in the year of our Lord One thousand
eight hundred and eighty three
