COMPLETE SPECIFICATION.
Apparatus for Grinding China-ink and the like.
I ADOLF JAKOB RYNIKER, of Interlaken in the Republic of Switzerland, 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 :-
This invention has for its object an apparatus by means of which china-ink,
colour, and the like may be ground in an easy, cleanly and economical manner.
One arrangement of this apparatus is shown in the accompanying sheet of
illustrative drawings, Figs. 1 and 2 of which show two partly sectional elevations
of the apparatus, whilst Figs. 3 and 4 show detail constructions.
In a frame a, which may be placed on a table by means of a plate 6 which serves
as a rest for the colour cup t and which may be fixed to this table by means of a
screw c, works a vertical shaft d. This shaft can be rapidly rotated by means of
the wheels e e¹ and e' of which the wheel e' is connected with a handle and serves as
a crank-disc.
On the shaft d is placed a crosshead of movable up and down on the shaft d⚫and
which in its lowest position is held fast on the shaft & by means of a wedge g. This
wedge g, provided with two gudgeons g' which can slide in a slit in the forked
shaped lever i revoluble on the axis h, is held fast in the slot by means of the said
gudgeons g', the lever i and the spiral spring k.
In the crosshead fare fixed, parallel to the shaft d, two sockets and which
serve to take up and to guide the pieces of china-ink m and m¹, which latter are
pressed against the bottom of the colour-cup by spiral springs n and n¹ placed
over the china-ink pieces m and m¹ inside the sockets and land which china-ink
pieces can give off colouring matter to the water placed in the colour cup when
rotated by the shaft d.
In order to regulate the pressure of the springs acting upon the china-ink pieces,
or to keep this pressure uniform the springs n and n¹ can be strained or unstrained,
according to requirement by means of the plates o and o' guided in slits v of the
sockets and land of the nuts p and p¹ screwed upon the sockets and l' which are
provided with threads on the outside.
In order to prevent the china-ink pieces m and m² from falling out or from being
pushed out of the sockets by the springs n and n¹ when moving the crosshead f
upwards, which is necessary when the colour cup has to be taken away, the
apparatus is provided with the following arrangement. Across and in front of the
two sockets and is placed, a little below them and parallel to the crosshead f, a
double armed lever q in such way that it can be introduced by means of the lower
end of the forked shaped lever i into slits r and r¹ provided in the sockets / and /
and be so pressed against the china-ink pieces that these are firmly pressed against
the part of the inner side of the socket wall situated opposite to the lever q and so
hold fast in the sockets. Thus every time the wedge g is drawn out of the shaft d
in order to move the body upwards, the china-ink pieces are pressed against the
walls of the sockets so that they can in no case fall out or be pushed out when the
crosshead is moved upwards. By means of a screws placed in the lever qat
the place where this latter is acted upon by the lever i the displacement of the
lever g can be regulated.
As the spiral spring k always presses the wedge g against the shaft d when the
crosshead is moved upwards it keeps fast the crosshead fin any position.

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. An apparatus for grinding china-ink, colour and the like comprising sockets"
movable up and down and capable of rotary movement, in each of which sockets a
piece of china-ink or colour is so placed under the action of springs that these pieces
of china-ink or colour are pressed with their lower faces against the bottom of a
colour-cup and give off colouring matter to the water placed in the colour cup when
the sockets are rotated, the pressure of the springs being regulated as desired
substantially as described.
2. In the apparatus claimed by Claim 1; an arrangement for holding fast the
pieces of china-ink or colour in the sockets which is so arranged as to be actuated
as soon as the sockets are lifted or removed from the colour cup in order to prevent
the pieces of china-ink or colour from falling out or from being pushed out of the
sockets when these latter are moved upwards substantially as described.
3. The arrangement and construction of apparatus for grinding china-ink, colour,
and the like, substantially as described with reference to the drawings.
