PROVISIONAL SPECIFICATION.
An Improvement in Inking Apparatus for Reciprocating Table
Printing Machines.
We, JOSEPH FOSTER, FRANCIS FOSTER, and JAMES YATES FOSTER all of
Bow Lane Iron Works, Preston in the County of Lancaster, Engineers, do hereby
declare the nature of this invention to be as follows:-
The table of a printing machine is usually moved by a crank causing it to travel
in both directions at varying speed, and thus the inking rollers in contact with the
forme have imparted to them rotation in both directions and at varying speeds.
Our invention relates to means of delivering ink from a system of supply and
distribution rollers rotating at uniform speed in one direction to the system of
inking rollers which rotate alternately in both directions and at varying speed.
For this purpose, between a uniformly rotating distributing drum, supplied from a
ductor and provided with distributing rollers in the usual way, and the inking
rollers we mount a pair of transfer rollers on the opposite ends of a sway beam or
equal armed lever which is caused to oscillate so as to bring each transfer roller
alternately into contact with the distributing drum, while the other transfer roller
is in contact with one or more of the inking rollers. As these transfer rollers are
free to revolve, the one is driven for a time by the distributing roller at constant
speed, taking ink from it, while the other is driven by the inking rollers at varying
speed giving ink to them.

An Improvement in Inking Apparatus for Reciprocating Table
Printing Machines.
We, JOSEPH FOSTER, FRANCIS FOSTER, and JAMES YATES FOSTER, all of
Bow Lane Iron Works, Preston, in the County of Lancaster, Engineers, 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:-
The table of a printing machine is usually moved by a crank causing it to travel
in both directions at varying speed, and thus the inking rollers in contact with the
forme have imparted to them rotation in both directions and at varying speeds.
Our invention relates to means of delivering ink from a system of supply and
distribution rollers rotating at uniform speed in one direction to the system of
inking rollers which rotate alternately in both directions and at varying speed.
For this purpose, we construct and arrange the inking apparatus as shewn in
transverse section on the accompanying drawing.
Between a uniformly rotating distributing drum A supplied from a ductor B and
provided with distributing rollers C in the usual way, and the inking rollers D, we
mount a pair of transfer rollers E E¹ on the opposite ends of a sway beam or equal
SD 077

page_text: armed lever F which is caused to oscillate so as to bring each of the transfer
rollers E E' alternately into contact with the distributing drum A, while the other
transfer roller is in contact with one or more of the inking rollers D.
As the transfer rollers E E¹ are free to revolve, the one is driven for a time by
the distributing roller A at constant speed, taking ink from it, while the other is
driven by the inking rollers D at varying speed giving ink to them.
The sway beam F may be caused to oscillate in various ways; as shewn in the
drawing, a double cam. G causes a sliding rod H to advance bearing against an
arm projecting from the sway beam moving it in opposition to a spring K which
causes the return stroke.
Having now particularly described and ascertained the nature of this inven-
tion and in what. manner the same is to be performed we declare that what we
claim is :-
:-
In inking apparatus for a reciprocating table printing machine the combination
of a uniformly rotating inking drum, and the irregularly revolving inking rollers, a
pair of rollers mounted on opposite ends of an oscillating sway beam, so as
alternately to revolve with the drum taking ink from it and to revolve with the
inking rollers giving ink to them, substantially as described.
Dated this 7th day of April 1896.
