Improvements in or relating to Colour Rubbing Apparatus.
I, PHILIP FURLONG, of 102, Barons Court Road, West Kensington, London,
W., Agent, do hereby declare the nature of my said invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:-
The object of my invention is to effect improvements in or relating to apparatus
used for rubbing or grinding indian ink or solid colour with water or other
liquid for the production of a fluid for use in drawing or colouring; and my
invention consists in providing improved means for regulating the pressure of the
solid substance upon the colour slant or cup and for generally adjusting the
solid substance relatively to the apparatus.
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings in which similar
letters of reference indicate corresponding parts.
Fig. 1 is a diagrammatical view of a colour rubbing apparatus.
Fig. 2 is a side view partly in section illustrating the application of my
invention.
Fig. 3 is a sectional elevation of the colour holder and its fittings.
Fig. 4 is a side view of a modified form and arrangement of a colour holder.
The colour rubbing apparatus consists of a frame a of any suitable material
and design and preferably hinged to the base board b so as to be capable of
folding when out of use; a shaft e carrying a bevel pinion at its upper end and
the colour holder at its lower end, and a bevel wheel fitted with a handle by
means of which the shaft and colour holder are rotated.
The colour holder consists of a barrel d secured on the side of the shaft c, so
that its motion is round about the axis of the shaft, the barrel being fitted
with an inner barrel e in which the solid colour is held. The barrel e is capable
of sliding within the barrel d, the former being provided with studs e¹ which
work through slots d'in the latter. The upper end of the barrel d contains a
spring held in place by the ring g and acting upon the end of the barrel e
whereby the latter is projected downwardly; but in order to more readily and
efficiently regulate this downward pressure a pair of springs such as shown at h are
provided the upward pressure of which is rendered adjustable by any well
known means.

Preferably, the colour holder is formed so that the solid stick of colour may
be inserted from the top; any suitable means of clamping it in the holder may
be provided, a set screw being shown in the drawings for the purpose. The
slots d may be formed with notches in which the studs e and set screw i
may be placed when it is desired to hold the solid colour in a raised position.
Also the length of the shaft e may be rendered adjustable, and a second tapped
hole may be provided to allow of small portions of solid colour being used.
In Fig. 4 the pressure of the solid colour on the colour slant or cup is obtained
by a pair of rubber bands k, which pass round the end projections and are
coiled upon the studs e¹; or two pairs of rubber bands may be employed, one

page_text: pair each side, the pressure being regulated by the thickness or strength of the
bands.
This modification provides a cheap and ready method of carrying out this
part of my invention.
Having now particularly described and ascertained the nature of my said
invention, and, in what manner the same is to be performed, I declare that what
I claim is:-
1. In a colour rubbing or grinding apparatus, the application and use of the
colour holder constructed, arranged, and operating substantially as herein-before
described and illustrated by Figs. and 3 of the drawings.
2. In a colour rubbing or grinding apparatus, the means for obtaining the
desired pressure of the solid colour on the slant, or cup, substantially as set
forth, and as illustrated in Fig. 4 of the drawings.
3. The improved colour rubbing or grinding apparatus, substantially as
specified.
