PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Printing Ornamental Fabrics.
We, Sir ARCHIBALD ORR EWING, Baronet, of Ballikinrain Castle, in the
County of Stirling, North Britain, and JOHN STOBO, Foreman Mechanic, of
Levenbank Works, Jamestown, in the County of Dumbarton, North Britain, do
hereby declare the nature of this invention to be as follows, that is to say :-
This invention relates to printing apparatus of the kind in which the fabric to be
ornamentally printed passes downwards to a roller then round under the roller and
upwards again, and a printing plate moves horizontally with its printing surface
uppermost, and prints on the fabric at the bottom of the roller round which the
fabric passes.
Our object is to adapt the apparatus for printing dress or scarf or
other patterns having end parts or borders different from the middle parts or
fillings, in a more convenient manner than heretofore and with less time and labor.
When the borders or end parts comprise pines or other unsymmetrical devices it
is generally necessary for such parts at one border or end to be reversed in position
as compared with the other border or end. For this purpose we arrange the plate
for printing the borders or ends so that it can be easily and quickly turned half
round so as to reverse the pattern. The plate is supported and fixed on a carriage
which moves on rollers; and at a part of the machine convenient for turning the
carriage there is a turntable made with a vertical trunnion on its underside, this
trunnion fitting and being capable of turning and moving vertically in a guide
bearing fixed to the framing of the machine. The trunnion is made with a socket
having a conical upper end. In a suitable position a vertical spindle made with a
conical upper end fitting in the turntable socket and guided to move vertically is
provided, and a treadle or foot lever is arranged for acting on the vertical spindle,
which is however kept down by a spring or weight when the foot lever is not being
depressed.
On the top of the turntable there are two diametrically opposite conical projec-
tions which engage in conical indentations in the underside of the carriage and
keep the carriage central whilst being turned. When the carriage has been
brought into the position for being turned, the turntable is raised by means of the
treadle and vertical spindle and bears up the carriage sufficiently to allow of its
being easily turned.
When a heavy printing plate is used or in any case in which it may be considered
desirable, the turntable may be lifted by means of a cylinder and piston actuated
by steam or water.

page_text: to be performed, to be particularly described and ascertained in and by the
following statement, that is to say :-
This invention relates to printing apparatus of the kind in which the fabric to be
ornamentally printed passes downwards to a roller then round under the roller and
upwards again, and a printing plate moves horizontally with its printing surface
uppermost, and prints on the fabric at the bottom of the roller round which the
fabric passes.
Our object is to adapt the apparatus for printing dress or scarf or
other patterns having end parts or borders different from the middle parts or fillings,
in a more convenient manner than heretofore and with less time and labor.
When the borders or end parts comprise pines or other unsymmetrical devices it
is generally necessary for such parts at one border or end to be reversed in position
as compared with the other border or end. For this purpose we arrange the plate
for printing the borders or ends so that it can be easily and quickly turned half
round so as to reverse the pattern. The plate is supported and fixed on a carriage
which moves on rollers; and at a part of the machine convenient for turning the
carriage, which is provided with a pair of handles at each end, there is a turntable
having a vertical trunnion, on its underside, made with a socket in which engages a
spindle movable vertically by means of a treadle, the spindle being kept down by
a spring or weight when the trendle is not being depressed.
On the top of the turntable there are diametrically opposite conical projections
which engage in conical indentations in the underside of the carriage and keep the
carriage central whilst being turned. The turntable is raised by means of the
treadle and vertical spindle and bears up the carriage sufficiently to allow of its
being easily turned.
When a heavy printing plate is used or in any case in which it may be considered
desirable, the turntable may be lifted by means of a cylinder and piston actuated
by steam or water.
And in order that the said invention and the manner of performing the same
may be properly understood we hereunto append a sheet of explanatory drawings
to be hereinafter referred to and showing the apparatus for printing ornamental
fabrics as made with our present improvements.
Figure, 1, of the drawings, is a plan, and Figure, 2, a longitudinal vertical
section of a part of the printing machine. In these drawings the same reference
letters are used to mark the saine or like parts wherever they are repeated.
As shown in the drawings, the plate, A, is supported and adjustably fixed on a
carriage, B, which moves on guide rollers, C, arranged along the two sides of the
machine. The carriage, B, is provided with a pair of handles, D; at each end for
conveniently moving and turning it from the end in whatever position it may
happen to be; and at a part of the machine convenient for turning the carriage
there is a turntable, E, made with a vertical trunnion, F, on its underside, this
trunnion fitting and being capable of turning and moving vertically in a guide
bearing, G, fixed to the framing of the machine. The trunnion, F, is made with a
socket having a conical upper end. In a suitable position there is provided a
vertical spindle, H, made with a conical upper end fitting in the trunnion socket
and guided to move vertically in guides, J, fixed to cross bars, K, on the machine;
and a treadle or foot lever, L, is arranged for acting on the vertical spindle, H,
which is however kept down by a spring, M, and weight, N, applied to the spindle,
when the foot lever, L, is not being depressed. The foot lever, L, is centered on a
bracket, P, and a bracket, Q, with a stop, R, limits the movement of the lever.
On the top of the turntable, E, there are two pairs of diametrically opposite
projections, S, which engage in conical indentations, T, in the underside of the
carriage, B, and keep the carriage central whilst being turned. When the
carriage, B, has been brought into the position for being turned, the turntable, E,
is raised by the worker depressing the treadle, L, and thereby raising the vertical
spindle, H, which bears up the turntable, E, and carriage, B, sufficiently to allow of
their being easily turned by means of the handles, D.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is: 1-
In apparatus of the kind hereinbefore referred to for printing ornamental fabrics
providing a turntable having on its top conical projections and on its underside a
trunnion made with a socket in which engages a spindle movable vertically by
means of a treadle, or of a cylinder and piston actuated by steam or water, so as
to raise the turntable and cause its conical projections to engage in conical inden-
tations in the underside of, and bear up, the plate carriage which is fitted with
handles at both ends, substantially as and for the purposes hereinbefore
described.
