Complete Specification Left, 11th Mar., 1893-Accepted, 6th May, 1893
PROVISIONAL SPECIFICATION.
Improvements in Machines for Printing Fabrics.
We, WILLIAM PICKUP, and WILLIAM KNOWLES, of Orchard Street,
Pendleton, in the County of Lancaster, Engineers, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in machines for printing fabrics in an
intermittent manner, such as shawls, scarves, and the like and has for its object to
provide simple and effective means for bringing into position the printing roller for
printing not only at half yards but also at quarter yards, as may be required for
different lengths of shawls, scarves, or the like.
To accomplish this we key to one end of the printing roller a bush having a
shoulder or flange, upon which bush is arranged to rotate loosely, or with it
through frictional contact, as may be required, a spur wheel in gear with a driving
wheel. The shoulder or flange end of this wheel bush is furnished with an
adjustable projection or finger, adapted to be operated upon by another adjustable
projection or finger, carried by a bracket fixed to the side of the printing machine
frame. The said spur wheel is rotated continuously by the aforesaid driving
wheel.
When the printing roller is not in operation, the said spur wheel runs loose on
its bush and the projection or finger on the latter is in contact with that of the said
bracket, whilst on the printing roller being raised the said projections or fingers
become disengaged, so as to allow the said spur wheel to take with it the bush and
thus rotate the printing roller.
In lieu of employing two projections or fingers as described, we may use on the
said bracket a spring bolt, adapted to engage in a recess formed in the periphery
of a rim on the shoulder or flange end of the aforesaid bush.

COMPLETE SPECIFICATION.
Improvements in Machines for Printing Fabrics,
We, WILLIAM PICKUP, and WILLIAM KNOWLES, of Orchard Street,
Pendleton, 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 :-
This invention relates to improvements in machines for printing fabrics in an
intermittent manner, such as shawls, scarves, and the like and has for its object to
provide simple and effective means for bringing into position the printing rollers for
printing not only at half yards but also at quarter yards, as may be required for
different lengths of shawls, scarves, or the like.
And in order that our invention may be more fully understood we have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is partially a side view and partially a section and Fig. 2 an end view of
the part of a printing machine to which our improvements are applied. Fig. 3 is
also an end view of a modification thereof.
In carrying out our invention and referring to Figs. 1 & 2, we key or otherwise
fasten to one end of the printing roller shaft a, for instance through the medium

page_text: of a bush a', a bush 6 having a shoulder or flange 6' formed thereon or secured
thereto. The bush a¹ has at the front end a lug a² carrying a set screw a³ adapted
to operate between two lugs at, which are formed on the bush b, b', and allow of
axially adjusting the latter on the bush al. Upon the bush b, b¹ is arranged to
rotate loosely or with it through frictional contact, for instance in the mauner as
shown in the drawing, as may be required, a spur wheel c in gear with the respective
driving wheel (not shown). The shoulder or flange 6 of the wheel bush bis
furnished, preferably on its periphery, with an adjustable projection or finger d,
adapted to be operated upon by another adjustable projection or finger e, which
may be in the form of a spring bolt, carried by a bracket f fixed to the side of the
printing machine frame g. The spur wheel e is rotated continuously by the aforesaid
driving wheel (not shown).
When the printing roller is not in operation the spur wheel c runs loose on its
bush b, b, and the projection or finger d on the same comes in contact with the
projection or finger e on the bracket f, whilst on the printing roller being suitably
raised the projections or fingers d & e become disengaged, so as to allow the spur
wheel c to take with it through frictional contact, as hereinbefore referred to the
bush b, b and thus rotate the printing roller.
In lieu of employing two projections or fingers as described, we may use on the
bracket a spring bolt d, see Fig. 3, adapted to engage in a recess d¹ formed in
the side or the periphery of the shoulder or flange 6 of the bush b.
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 machines for printing fabrics."
1st. The general construction and combination of parts constituting our
improvements operating substantially as and for the purpose set forth.
2nd. The combination of a spur wheel c adapted to rotate, by frictional contact,
a bush b, b', suitably fastened to one end of the printing roller shaft a and having a
finger or projection d or recess d', adapted to operate in conjunction with another
finger or projection e, substantially as and for the purpose set forth.
