We, JAMES KERR of the firm of F. Steiner & Company of Church in the County
of Lancaster Turkey Red Dyers and Printers and JAMES NASMYTH WILSON of
Southport in the County of Lancaster Consulting Engineer do hereby declare the
nature of this Invention to be as follows:-
Our Invention relates to what are known as intermittent printing machines for
effecting the movement of the printing roller to and from the fabric at predetermined
intervals. According to our Invention we use any suitable arrangement of mechanism
which at predetermined intervals removes the roller-driving, or box wheel, out of gear with
the crown wheel so as to cause the printing roller to remain inactive as long as desired
and then to be brought into gear again and onto the cloth (or the like) for printing
at the necessary intervals. We do not restrict ourselves to any particular mechanism
for moving the box wheel as it may be effected in a variety of ways. By this means
we are enabled to print any length of material with any and but one circumference
of roller and thus save the expense and time involved in re-engraving a pattern, or
design, on different sized rollers.

We, JAMES KERR, of the Firm of F. Steiner and Company, of Church in the County
of Lancaster, Turkey Red Dyers and Printers, and JAMES NASMYTH WILSON of
Southport in the County of Lancaster, Consulting Engineer, 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 :-
Our Invention relates to what are known as intermittent printing machines wherein
the printing roller moves to the cloth, or other material, to print thereon and then
moves therefrom, these movements being effected at predetermined intervals.
According to our Invention we use mechanism which not only moves the printing
roller to and from the cloth or other material but which at corresponding intervals
removes the roller-driving or "box wheel" out of gear with the "crown wheel" and
replaces it in gear therewith so as to cause the printing roller to remain inactive as
long as desired and to be restarted and brought into gear again and on to the cloth
(or the like) for printing at the necessary intervals. By this means we are enabled
to print any length of material with any and but one circumference of roller and thus
save the expense and time involved in re-engraving a pattern or design on different
sized rollers.
In order that our Invention and the manner in which it can be carried into effect
may be fully understood we will describe the same more particularly with reference
to the accompanying drawing whereon Figures 1 and 2 are end elevations and
Figure 3 a plan partly in section showing so much of a printing machine as is
necessary for the purpose of describing our Invention the same letters of reference
indicating corresponding parts in all the Figures.
**
A is a portion of the frame at one side of the printing machine. A portion of the
main bowl round which the material being printed passes is represented at B being
mounted on a shaft J. U is a portion of the "crown-wheel" which drives a box-
wheelD on the axis of a printing roller E to which rotary motion is transmitted
through a mandril F in the direction indicated by the " arrow.
In order to enable the roller E to be automatically removed from the fabric being
printed and the box wheel D thrown out of gear with the "crown-wheel" C adjustable
push bars G are provided (on both sides of the machine). One end of each
bar G acts on the mandril F the other end having by preference a roller N which
hears against and is actuated by cams H fixed upon the shaft J upon which the main
bow! B revolves. Fixed to the same shaft. J or if desired to the cams H is an arm K
or if preferred a wheel having on its periphery suitable projecting pieces or wipers.
Upon the mandril F is fixed an adjustable arm or lever L which is actuated by the
arm K at predetermined intervals when it is desired to bring the box wheel Ď into
gear with the "Crown-wheel" Cafter the periods of inactivity of the printing
roller E.

page_text: The apparatus operates in the following manner-The necessary pressure upon the
printing roller E is adjusted by the screw M which acts on the axis of the printing
roller through springs or levers not shown in the drawing. With the box wheel D
in gear as in Figure 1 the push bars G are adjusted so that whilst the one end bears
against the mandril F the rollers N just clear the bottom of the recess O in the cams H.
The roller E is now on the fabric and remains in this position until the rollers N come
in contact with the point or rise P of the cams H. This increase of diameter of the
cam compresses the springs between the axis of the roller E and the adjusting screws M
and pushes the said roller so far off the fabric as to prevent printing but the wheel D
remains in gear with the wheel C until the roller N comes in contact with the point Q
of the cams H. When the roller N mounts this second rise of the cam the wheel D
is thrown completely out of gear with the wheel and a lever L fastened to the
mandril F (or, if preferred to the box-wheel D) is in a horizontal and radial position
as in Figures 2 and 3 and remains so until actuated by the arm K prior to the
reengaging of the wheels D and which is effected as follows.
After the roller N passes the rise of the cam H it travels along the concentric
part R of the cam until close to the point S. At this moment the arm K comes in
contact with the arm or lever L as in Figure 2 and by pushing up this lever imparts
a partial rotary motion to the wheel D to correct the position of the teeth. The
recessed part or smaller diameter of the cam at S then comes opposite the roller N
and the springs between the adjusting screws M and the axis of the printing roller
push this axis towards the main bowl B and cause the roller N to drop into the recess
at S on the cam allowing the wheels D and C to be in "half gear" until the point T
on the cam is reached by the roller N. The wheel D is then moved so as to be
completely in gear with the wheel C and the roller E comes in contact with the fabric
for printing remaining in this position until the roller N reaches the point P of the
cam H and again pushes back the printing roller as herein before described.
We have described the invention as applied to one printing roller only but it is
evident that the apparatus is equally applicable to two or more of such rollers in
one machine.
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.-
First. In combination or connection with machinery or apparatus for printing from
rollers the improved means for automatically stopping and starting the printing roller
or rollers when off the material being printed by moving the wheel on the axis of the
printing roller bodily out of gear with the wheel on the axis of the main bowl
substantially as and for the purpose hereinbefore described.
Second. For or in combination or connection with machinery or apparatus for
printing from rollers the arrangement of mechanism consisting of cams and push bars
or their equivalent for engaging and disengaging the "box-wheel" with and from
the "crown-wheel" substantially as and for the purpose hereinbefore explained and
illustrated respectively in Figures 1, 2 and 3 of the accompanying drawing.
Third. The arrangements and combinations of parts constituting the improvements
in printing machines substantially as hereinbefore described.
