Year: 1866

page_text: LETTERS PATENT to James Barker, of Whiteinch, in the County of
Lanark, North Britain, Foreman to Messieurs Wylie and Lochhead,
Paper Hanging Manufacturers, for the Invention of "IMPROVEMENTS IN
Sealed the 22nd March 1867, and dated the 25th September 1866.
PROVISIONAL SPECIFICATION left by the said James Barker at the
Office of the Commissioners of Patents, with his Petition, on the
25th September 1866.
I, JAMES BARKER, of Whiteinch, in the County of Lanark, North Britain,
Foreman to Messieurs Wylie and Lochhead, Paper Hanging Manufacturers,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPARATUS EMPLOYED IN PRINTING AND FOLDING PAPER HANGINGS AND WOVEN
FABRICS," to be as follows, that is to say :-
This Invention relates to improvements in apparatus employed in printing
and folding paper hangings and woven fabrics, some of the improvements
having for their object to facilitate the adjustment of the printing rollers,

page_text: whilst the object of the remainder is to effect the lapping or folding of the
paper or woven fabric by self-acting means.
"
Hitherto when printing by means of cylinder printing machines with several
colors the several rollers have been adjusted or pitched so as to make their
impressions on the paper or fabric all register accurately together by a tentative
process involving loss of time and waste of material in consequence of the
rollers having to be drawn out of gear for re-adjustment. Minute adjustments
are effected by means of an adjustable bush fixed on the roller spindle and
carrying the toothed wheel which gears with the large pitch" wheel on the
drum shaft, this bush being made in two parts, one fixed on the spindle, and
the other having the toothed wheel fixed on it, whilst a worm wheel on one is
in gear with a tangent screw on the other, whereby the position of the
spindle relatively to the toothed wheel can be altered as required; this screw
adjustment is in practice much too slow except for very small adjustments.
The adjusting bush has hitherto been fixed on the roller spindle by an
ordinary pinching screw, and without any means being adopted for
determining its precise position on the spindle.
By the present Iuvention a conical indentation is formed in the spindle,
and the pinching screw is formed with a conical point to enter the
indentation. For finding the correct position for the indentation a pinching
screw is used with a conical point on its outer end also. A thread or cord is
beld tight so as to coincide with the register points of the pattern at opposite
ends of the roller (care being taken to form these register points on the
pattern surface of the roller accurately in line). The bush is then turned
round until the pinching screw is accurately under the thread, and the
pinching screw is screwed in to mark on the spindle the point for the
indentation. In making the adjustment just described the position of
the bush lengthways on the spindle is accurately adjusted by a gauge or
measure, so that the lateral guard lines of the several impressions may all
coincide. A mark is put on the toothed wheel, by preference in the line of
the pinching screw and register points, and when the printing rollers are
being entered into the machine a mark is put on the large "pitch" wheel
gearing with the roller wheels opposite the mark of the wheel of the roller
first entered. The large "pitch" wheel is then turned to bring its mark
opposite the positions of the other rollers, and these are entered in succession,
each with its mark coinciding with that on the large wheel at the time of
entering. These arrangements allow of the rollers being at once placed in
their proper positions, any slight inaccuracy still remaining being quite
within the control of the tangent screws without its being ever necessary to

page_text: draw the rollers out of gear. The paper or fabric as printed passes in some
cases from the printing machine into and along a drying stove, and returns
towards the machine again, near which a pair of suitably driven rollers draw
it into a swinging case, by which it is laid in folds on a carriage or platform
below. The swinging case is centered near the drawing rollers, and receives
the paper or fabric at its upper end, which is at or near the centre of its
motion; the paper or fabric passes down through it and out at its bottom
swinging end, and as the folds are laid weighted boards or plates descend and
press them down at the ends. The pressing down boards are guided by
stretched cords or otherwise, and are raised intermittently and alternately by
cords passing over pulleys and attached to levers or arms projecting up from
the swinging casing. The casing is made to swing or reciprocate by means of
a revolving crank or eccentric with whatever intermediate connection may be
convenient. The folding or lapping mechanism may be applied quite
separately from the printing machine, and for other woven fabrics besides
printed ones.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Barker in the Great Seal Patent Office on the
23rd March 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
BARKER, of Whiteinch, in the County of Lanark, North Britain, Foreman to
Messieurs Wylie and Lochhead, Paper Hanging Manufacturers, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of September, in the year of our
Lord One thousand eight hundred and sixty-six, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me;
the said James Barker, Her special licence that I, the said James Barker,
my executors, administrators, and assigns, or such others as I, the said
James Barker, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
APPARATUS EMPLOYED IN PRINTING AND FOLDING PAPER HANGINGS AND WOVEN
FABRICS," upon the condition (amongst others) that I, the said James Barker,

page_text: my executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said James Barker, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement in writing, reference being had to the accompanying Drawings,
that is to say:-
My said Invention relates to improvements in apparatus employed in
printing and folding paper hangings and woven fabrics, some of the improve-
ments having for their object to facilitate the adjustment of the printing
rollers, whilst the object of the remainder is to effect the folding or lapping of
the paper or woven fabric by self-acting means.
And in order that my said Invention and the manner of performing the
same may be properly understood, I have hereunto appended a Sheet of
explanatory Drawings to be herein-after referred to, and representing con-
venient and practically successful modifications of my improved arrangements.
Figures 1 and 2 are elevations at right angles to each other of parts of a
cylinder printing machine requiring to be referred to in explaining the first
portion of my improvements, whilst Figures 3 and 4 are elevations at right
angles to each other, of my improved folding apparatus, the frame of the
printing machine being also delineated in Figure 3 to show the connection of
the parts. The same reference numerals are used to mark the same or like
parts in all the Figures in which they occur.
Hitherto, when printing by means of cylinder printing machines with several
colors, the several printing rollers 1 have been adjusted or pitched so as to make
th ir impressions on the paper or fabric all register accurately together by a tenta-
tive process involving loss of time and waste of material in consequence of the
rollers I having to be drawn out of gear for re-adjustment. Minute adjustments
are effected by means of an adjustable bush 2 (shown in section in Figure 1)
fixed on the roller spindle 3, and carrying the toothed wheel 4, which gears with
the large "pitch" wheel 5 on the shaft 6 of the drum 7, this bush 2 being made
in two parts, one 8 fixed on the spindle 3, and the other 2 having the toothed
wheel 4 fixed on it, whilst a worm wheel formed on the part 8 is in gear with a
tangent screw 9 carried by the other 2, whereby the position of the spindle 3
relatively to the toothed-wheel 4 can be altered as required; this screw

page_text: adjustment is in practice much too slow, except for very small adjustments.
The adjusting bush 2, 8, has hitherto been fixed on the roller spindle by
an ordinary pinching screw, and without any means being adopted for
determining its precise position on the spindle.

By my present Invention a conical indentation is formed in the spindle 8, and
the pinching screw 10 is formed with a conical point to enter the indentation.
For finding the correct position for the indentation a pinching screw is used with
a conical point at its outer end also, and the pinching screw 10, delineated in
Figures 1 and 2, is of this kind, but the pinching screws for actually fixing the
bushes on the spindles for work do not require the conical points at their outer
ends after the correct positions of the indentations in the roller spindles have been
once ascertained in each case. The bush 2, 8, being put on the spindle 3, and
the pinching screw 10 being in its place, but not screwed hard in a thread or
cord, is held tight, so as to coincide with the register points 11, 12, of the pattern
at opposite ends of the roller 1 (care being taken to form these register points
on the pattern surface of the roller accurately in line); the bush 2, 8, is then
turned round until the pinching screw 10 is accurately under the thread, and
the pinching screw is screwed in to mark on the spindle 3, the point for the
indentation. In making the adjustment just described the position of the
bush 2, 8, lengthways on the spindle 3 is accurately adjusted by a gauge or
measure, so that the lateral guard lines of the several impressions.may all
coincide, and this gauge or measure is made of such a length that when the roller
1 is placed in the machine its toothed wheel 4 will have its outside flush with the
outside of the pitch wheel 5. A chalk or other mark is put on the toothed
wheel 4, by preference in the line of the pinching screw 10 and register points
11, 12, and when the printing rollers 1 are being entered into the machine a
similar mark is put on the large pitch wheel 5 opposite the mark of the
wheel 4 of the roller 1 first entered; the large pitch wheel 5 is then turned
to bring its (single) mark opposite the positions of the other rollers 1, and
these are entered in succession, each with its mark coinciding with that on the
large wheel 5 at the time of entering. These arrangements allow of the
rollers 1 being at once placed in their proper positions, any slight inaccuracy
still remaining being quite within the control of the tangent screws 9 without
its being ever necessary to draw the rollers out of gear. The paper or fabric
(shown by a blue line in Figure 3) as printed passes (in some cases) from the
printing machine into and along a drying stove and returns towards the
machine again, as at.18, Figure 3. Near the machine a pair of suitably
driven rollers 14, 15, draw it into a swinging case 16, by which it is laid in
folds upon a carriage 17 or platform below. The swinging case, the form of

page_text: which will be clearly comprehended from the Drawing, is centred near the
drawing rollers 14, 15, on pendent brackets 18, and receives the paper or
fabric at its upper open end, which is at or near the centre of its motion;
the paper or fabric passes down through it and out at its bottom swinging
end, and as the folds are laid weighted boards or plates 19 descend and press
them down at the ends. The pressing down boards 19 are guided by stretched
cords 20 or otherwise, and are raised intermittently and alternately by cords
21 passing over pulleys and attached to levers or arms 22 projecting up from
the swinging casing 16. The casing 16 is made to swing by a revolving
crank 23 (or eccentric) connected by a rod 24 to one of the arms 22, or with
whatever intermediate connection may be convenient. In the example
delineated the motions of the folding apparatus are obtained from guide
rollers over which the blanket of the printing machine passes, and which
happen to be conveniently situated for the purpose, but they may obviously be
obtained in various other ways. The folding or lapping mechanism may be
applied quite separately from the printing machine, and for other woven
fabrics besides printed ones.
Having thus particularly described my said Invention, and the manner in
which the same is to be performed, I have to state that I do not restrict
myself to the precise details herein described or delineated, but that what I
believe to be novel and original, and claim as the Invention secured to me by
the herein-before in part recited Letters Patent is,--
1. The employing of improved means, substantially such as are herein-
before described, for adjusting the printing rollers of cylinder printing
machines.
And, 2. The constructing of apparatus for folding paper hangings and
woven fabrics, substantially in the improved manner herein-before described.
In witness whereof, I, the said James Barker, have hereunto set my
hand and seal, this Twenty-second day of March, in the year of our
Lord One thousand eight hundred and sixty-seven.
