PROVISIONAL SPECIFICATION.
An Improved Colour Rubbing Machine.
I, JANE HITCHEN, of 25 Caistor Street, Stockport in the County of Chester.
Spinster, do hereby declare the nature of this invention to be as follows:-
My invention is intended to perform mechanically the operation of preparing
such colours as indian ink for use by rubbing which operation has hitherto been
mainly performed by hand.
In carrying my invention into effect I construct a suitable frame of metal or
other material having a base to which is attached a slab, pan or other vessel con-
taining the liquid in which the indian ink or other colour is to be rubbed. The
frame work carries a vertical spindle or shaft driven preferably by bevel wheels by
hand or power. The vertical spindle carries a disc or arms rotated by the spindle
but so attached by feather and keyway or square or other section that the disc or
arms can slide freely on the spindle in the direction of its axis.
This disc carries one or more tubes or other clamping or holding devices into
which is or are slipped or fastened the stick of ink or colour to be rubbed. The
weight of the disc and other parts causes the end of the colour stick to bear upon
the slab or pan and when the gearing is rotated the colour is rubbed with any
desired degree of rapidity as arranged by the ratio of the gearing wheels. The
disc is allowed a sufficient sliding play upon the rotating spindle so that it can be
raised enough to get at the colour easily and insert or withdraw the colour stick or
sticks. Instead of a weighted disc I sometimes use a spiral spring to press against
the disc and thrust down the colour stick against the slab or pan and I also adopt
sliding tubes with slots and pegs to guide the sliding motion of the disc or driving
arms and drive the disc or arms.
In another modification I cause the pan to be rotated instead of the colour and
n this case the colour is held fixed and pressed down upon the pan by any con-
venient arrangement while the pan is rotated by suitable gearing.

COMPLETE SPECIFICATION.
An Improved Colour Rubbing Machine.
I, JANE HITCHEN, of 25 Caistor Street, Stockport, in the County of Chester,
Spinster, 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 :-
My invention is intended to perform mechanically the operation of preparing
such colours as indian ink for use by rubbing, which operation has hitherto been
mainly performed by hand.
In carrying my invention into effect I construct a machine in one manner as
illustrated in Figure 1 of the accompanying drawings, A being a suitable frame of
metal or other material having a base B to which is attached a slab, pan or other
vessel C containing the liquid in which the indian ink or other colour is to be
rubbed. The frame work carries a vertical spindle or shaft D driven preferably
[Price 8d.1

page_text: by bevil wheels E, E by hand or power. The vertical spindle carries a disc F or
arms rotated by the spindle but so attached by feather and keyway D' or square
or other section that the disc or arms can slide freely on the spindle in the
direction of its axis. This disc carries one or more tubes G or other clamping
or holding devices into which is or are slipped or fastened the stick of ink or
colour to be rubbed. The weight of the disc and other parts causes the end of the
colour stick to bear upon the slab or pan C and when the gearing is rotated
the colour is rubbed with any desired degree of rapidity as arranged by the ratio
of the gearing wheels. This disc is allowed a sufficient sliding play upon the
rotating spindle so that it can be raised enough to get at the colour easily and
insert or withdraw the colour stick or sticks.
In another form of my improved machine as shown in Figure 2, I arrange the
central driving spindle D' as a tube in which the central connecting spindle d may
slide this connecting spindle being square or provided with a key, or feather
if circular or with projecting arms or pins working slots, as shown, to permit of
its revolving with the outer tube D while being free to slide up within it. The
end cap HI arrange with its hole to suit the shape of the spindle d, and of a size
to allow of an easy sliding motion. I arrange a disc K or a series of arms to carry
the tubes or ink or colour holders G, which holders I secure by means of screws L
or other ordinary clamping devices. The ink or colour is always kept in position
upon the slab or pallet C by the weight of the tubes and fittings. I sometimes
arrange a circular connecting spindle to work in the main driving tube by pro-
viding projecting pins or cotters from the central spindle to work in holes or slots
formed within the tube.
When the ink or colour is to be rubbed down very quickly and somewhat
coarsely, I provide for contact between the bottom of the ink or colour and the
saucer or pan by placing a spiral spring M around the connecting spindle d', as
illustrated on Sheet 2, Figure 3 being a sectional elevation and Figure 4 a plan
of the arrangement I employ.
The central driving tubular spindle D² I connect to the top wheel E' as before
described and I arrange within the tubular spindle a connecting spindle having
projecting arms d², d³ working in suitable slots or grooves D³, D* within the lower
portion of the tube D². Thus the motion of the tube is communicated to the
central spindle, and a free sliding motion also permitted to the spindle during
motion so that the spring M may act to keep the ink or colour always in contact
with the surface of the pallet C.
Instead of rotating the ink or colour as before described I sometimes employ
the same system of holding the ink or colour within a disc or arms as illustrated in
Figures 1, 2, 3, and 4, but I cause the saucer or dish to revolve as illustrated on
Sheet 3, in which Figure 5 is a sectional elevation of my pan rotating machine
and Figure 6 is a plan of the same.
In this arrangement of my machine I mount the gearing N, O, P, upon spindles
carried upon the base B; the central spindle R carrying the wheel P I connect to
a pan or dish bolder S. This dish holder I make of any shape to suit the form
of saucer or dish to be employed, and I cause the dish to be held tightly within
the holder by means of elastic bands or wedges of any suitable material which I
place between the outer surface of the pan C and the inner surface of the holder S.
arrange any ratio of gearing wheels to suit the speed that is required for any
particular purpose of rubbing colour or ink.
I do not limit the application of my invention to any particular form or shape of
holder for retaining the ink or colour to be operated upon, neither do I employ
any particular number of holders upon any one machine, but I vary the arrange-
ment of holders, the shape of pallets and the shape of the holders to suit any
particular block of ink or colour that is to be rubbed down into a liquid state
without departing from the essential features of my invention as hereinbefore
described.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
(1) The construction of ink and colour rubbing machines having the ink or
colour holders or retainers arranged about a central spindle substantially as and
for the purposes herein before described, and as set forth in the accompanying
drawings.
(2) The application and arrangement to ink and colour rubbing machines of
gearing for revolving the ink or holders substantially as and for the purposes
hereinbefore described and as illustrated in Figures 1, 2, 3, and 4 of the accom-
panying drawings.
(3) The application and arrangement to ink and colour rubbing machines, of
gearing for revolving the pan or saucer substantially as hereinbefore described and
as illustrated in Figures 5 and 6 of the accompanying drawings.
(4) The construction and arrangement of ink and colour rubbing machines
substantially as and for the purposes hereinbefore described and as illustrated in
the accompanying drawings.
