I, GEORGE TAYLOR, Machine Builder of Robin Hood Street, Nottingham in the
County of the same town do hereby declare the nature of my invention for
AN IMPROVED INK DISC OR SLAB FOR THE BETTER DISTRIBUTION OF THE INK
PRINTING MACHINES, CHIEFLY APPLICABLE, ETC to be as follows:-
This Invention consists of a plane disc or slab provided with one, two, three or
more smaller discs, which, together with the larger disc are caused to revolve at
intervals by means hereinafter described, and the ink which is left on the face by
the inking rollers, as they traverse from the ink duct to the type, is distributed by
the movement given to the said discs.
The larger disc is caused to revolve upon its stalk-which has a bearing provided
for it in a suitable cross bar or other detail-by a ratchet lever, engaging with
ratchet teeth formed on the underneath side of the disc; the motion of the
ratchet lever is received from one of the reciprocating or oscillating parts of the
machine.
Fixed to the cross har, on the underneath side of the disc and concentric with it,
is a spur wheel.
At a convenient distance from the centre of the larger disc, one or more conical
holes are bored out to receive smaller discs; each of the smaller discs are provided
on their underneath sides with a spur pinion, which engage with the teeth of the
fixed spur wheel aforementioned. As the larger disc receives motion from the
ratchet lever or other suitable means, it will carry with it the smaller disc or discs,
and each of the small discs will at the same time alter their positions relative to
the larger disc, by the pinions with which they are provided, moving round the
fixed spur wheel, thus ensuring an effective distribution of the ink on the face of
the ink disc or slab.

I, GEORGE TAYLOR, of Coopers Factory, Roden Street Nottingham, Nottingham-
shire Machine Builder do hereby declare the nature of my invention for AN
IMPROVED INK DISC OR SLAB FOR THE BETTER DISTRIBUTION OF THE INK, ETC
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
This Invention consists of a plain disc or slab provided with one, two, three or
more smaller discs, which, together with the larger or main disc are caused to alter
their positions at intervals by means hereinafter described, and the ink which is
left on the face of the said discs by the inking rollers as they traverse from the ink
duct to the type is distributed by the movement given thereto.
The larger disc is caused to revolve upon its stalk-which has a bearing provided
for it in a cross bar or other detail-by a ratchet lever engaging with ratchet teeth
formed on the underneath side of the main disc; the motion of the ratchet lever
is received from one of the reciprocating or oscillating parts of the machine.
A spur wheel is fixed to the boss of the cross bar which contains the bearing for
the stalk of the main disc, the said wheel is fixed concentric with, and on the
underneath side of the main disc.
At a convenient distance from the centre of the larger disc one or more conical
or plain recesses are bored out to receive the smaller discs: each of the smaller discs
are provided on their underneath sides with a spur pinion which engage with the
teeth of the fixed spur wheel aforementioned; as the larger disc receives motion
from the ratchet lever or other suitable means, it will carry with it the smaller disc
or discs and each will at the same time alter their positions relative to the larger
disc, by the pinions with which they are provided moving partly 'round the fixed
spur wheel aforementioned thus ensuring with each motion of the machine an
effective distribution of ink on the face of the ink disc or slab. And in order that
my Invention may be fully understood I will now proceed to describe the Drawings
hereto annexed; the same letters of reference indicating corresponding parts in
both the figures.

page_text: the spur pinions contained on the stalks of the discs E and engage with the teeth
of the fixed spur wheel C. G is an arc plate usually fitted to or formed with the
type bed to prevent the edge of the ink plate cutting the inking rollers as they
traverse from the type to the ink duct.
•
On reference to the section it will be noticed that the disc E can be easily
withdrawn from the main disc to be cleaned as the top of the teeth and the plain
part of the stalk are turned parallel.
It will now be seen that when the disc A is moved it will carry with it the
smaller discs E, and the spur pinions F which gear with the fixed spur wheel C
will at the same time be made to alter their positions thus giving an effective
distribution of the ink left on the face of the discs, by the inking rollers.
Having now particularly described and ascertained the nature of my said
Invention and in what manner it is to be performed I declare that what
I claim ist
The arrangement and employment of a means for effecting the distribution of
ink in a printing machine consisting of a fixed spur wheel (C) of the disc or
discs (E) provided with spur pinions (F) on the stalks for the purpose herein before
described all substantially as set forth and illustrated in the accompanying sheet of
Drawings.
