Year: 1860

page_text: LETTERS PATENT to Edmund Keogh Dwyer, of Pimlico, in the County
of Middlesex, Gentleman, for the Invention of "IMPROVEMENTS IN MA-
GWYNEDY DAD DOWNLING CORASING AND FOLDING CLOTH"
Sealed the 23rd April 1861, and dated the 27th October 1860.
PROVISIONAL SPECIFICATION left by the said Edmund Keogh Dwyer at
the Office of the Commissioners of Patents, with his Petition, on the
27th October 1860.
I, EDMUND KEOGH DWYER, of Pimlico, in the County of Middlesex,
Gentleman, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY FOR DOUBLING, CREASING, AND FOLDING CLOTH," to be
as follows:-
My Invention is intended more particularly to apply to the creasing and
folding of such cloths as have been opened from bales for examination, and is
carried out as follows:-
The cloth in its opened state is placed in a box or trough, and is drawn over
a saddle frame or roller, the two sides hanging down. A revolving reel, with
the blades set at an angle to the horizontal line, beats against and assists in
turning up the cloth and bringing it from a horizontal to a vertical position,
and this is further assisted by a stationary frame; from this frame the cloth is
passed between horizontal rollers, where the creasing takes place; the creased
and doubled cloth then passes over guide rollers, being supported, if necessary,

page_text: and assisted onwards by a revolving flyer. From the guide rollers the cloth
is led down into a box or frame, over the top of which two rollers are made to
travel to and fro, and fold the cloth first one layer in one, and then the next
layer in the reverse direction. When required to stamp the cloth, I fix a
stamper over the saddle frame, and impart an up-and-down motion to it to
cause it to stamp at the parts desired.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edmund Keogh Dwyer in the Great Seal Patent Office on
the 27th April 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDMUND
KEOGH DWYER, of Pimlico, in the County of Middlesex, Gentleman, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of October, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Edmund Keogh Dwyer, Her special licence that I, the said Edmund
Keogh Dwyer, my executors, administrators, and assigns, or such others as I,

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 MACHINERY FOR DOUBLING, CREASING, AND FOLDING CLOTH,"
upon the condition (amongst others) that I, the said Edmund Keogh Dwyer,
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 Edmund Keogh Dwyer, 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 thereof, reference being had to the Drawings hereunto annexed,
(that is to say) :-

page_text: My Invention is intended more particularly to apply to the creasing and
folding of such cloths as have been opened for examination, and is carried out
as follows:-
The cloth in its opened state is placed in a box or trough, or on a table,
and is drawn over a saddle frame, the two sides hanging down, and is led on
to a revolving reel, as hereafter described; from this reel the cloth is passed
between rollers, and over a drum or cylinder to a box or frame, over the top
of which two rollers' are made to travel to and fro and fold the cloth, first one
layer in one, and then the next layer in the reverse direction. When required
to stamp the cloth, I fix a stamper or stamping rollers between the drum and
the table on which the cloth is folded; to cause it or them to stamp at the part
desired.
Figure 1 of the accompanying Drawings is a plan, and Figure 2 a side
elevation, of a saddle and reel constructed according to my Invention for
creasing and winding cloth preparatory to folding it, as hereafter described.
A is a table or frame, on which the cloth is laid in its opened state; B, B, are
guide rollers, held in arms, in which they are free to revolve, depending from
a frame D, extending across the table A; E is a creasing or central guide
roller grooved as shewn, and free to revolve on the back of the saddle F. The
rollers B, B, and E, are so arranged that they can be simultaneously raised to
place the cloth under them. This saddle F is slightly inclined from the centre
at about the part where the roller E touches it, and this incline increases until
it terminates at F¹ in a thin vertical end, as shewn, the sides gradually
sloping from the ridge of the back of the saddle; part of the saddle is shewn
broken, in order to economize space. G, G¹, are vertical rollers, mounted on
shafts g, g'; one g of which is free to revolve in bearings formed in the cross-
bars H, I, the other g' works in bearings at its lower end, and at its upper
in a slot against a bearing capable of adjustment by the screw hand wheel i,
so that the distance of one roller from another may be regulated, and by which
pressure is obtained when it is required to crease cloth which has not been
previously creased, as hereafter described; C is the reel on to which the
cloth is wound; it is mounted on a shaft I, and held in a suitable frame; the
lower end of this shaft I is dropped into a socket formed in the spindle of 'a
bevil wheel I', or connected to it in such manner that it is capable of being
easily removed therefrom; K is a pinion gearing into the wheel I'; it is
mounted on a shaft carrying a pulley L, round which a strap passes to another
pulley M, to which rotary motion is communicated by a winch handle N.
Instead of the last-mentioned pulley and winch, in some cases I communicate
motion to the reel by means of a treadle and strap extending from the table

page_text: to the reel; when the treadle is used, the rollers G, G³, move freely in their
bearings, the pressure produced by the wheel and screw not being in operation.
The upper end of the shaft I on which the reel is mounted is held in the frame
by a sliding piece and catch, so that it may be removed when required with
facility. The cloth being placed on, the table A is led under the rollers B, B,
as well as the roller E, where it becomes pressed on to the saddle; it is then
drawn along over the saddle, falling down on each side of it, and is led doubled
and in a vertical position between the rollers G, G', and is fastened by clips
or catches to the reel C; rotary motion is then communicated to the reel, and
continued until all the cloth laid on the table is drawn along, and wound in a
doubled and creased state on to the reel. When I require to re-crease cloth
from which the original crease has been shrunk, or to crease cloth which has
not been previously creased, greater power is required; for this purpose
I connect the bevil wheel I¹ with a wheel on the shaft g', on which the
roller G'is mounted, so that by uniting the two, by connecting rods and levers
ór other suitable appliances, I am enabled to communicate a rotary motion to
the roller G¹ directly from the bevil wheel I', and thus obtain a power in
addition to that obtained by the reel C, the power being applied by the hand
wheel.
:
Figure 3 is a side elevation, and Figure 4 a front view, of a machine for
folding cloth after having been creased, as last described, constructed according
to my Invention. A is the frame of the machine; B, B, are brackets, bolted
to the frame, and forked at their upper ends for receiving the reel C, on which
the cloth has been wound, as before described; E, E, are other brackets,
supporting in bearings formed at their upper ends the shaft F, on which the
drum or cylinder G is mounted; H, H³, are guides, supported by brackets E', E',
connected to and projecting from the brackets E, E; I is a pulley, round
which a strap I' passes to a smaller pulley K on the shaft L; M is a winch
handle for imparting motion to the shaft L; this shaft L extends about half
way across the machine, and carries a small pinion N in gear with the toothed
wheel O, which is mounted on a shaft O', working in bearings formed in the
frame A. The toothed wheel O carries a crank P attached to a connecting
rod Q, which latter is jointed to a frame R, detached views of which are given
in plan and section at Figures 5 and 6. The edges of this frame R from a
to b and c to d are free to slide in grooves formed in the frame A. S, S, are
rollers, free to run loosely in the frame; S', S¹, are guides, placed close to the
rollers, between which the cloth to be folded is passed, and which brings the
cloth immediately under the clips and spikes z, z, as hereafter more fully
described; T is a bed or table, on which the cloth is folded and laid; this bed.

page_text: a
is free to rise and fall in grooves formed in the frame A, and is. connected at
its under side to the racks V, V, into the teeth of which pinions V, V, take
and impart, as will be more clearly described hereafter, a downward motion to
the racks and bed or table T. The shaft L carries a pinion W, in gear with
a small toothed wheel X mounted on a shaft Y, extending across the machine.
This shaft Y carries cams X', X¹, a detached view of one of which, with a
jointed lever connected to it, is shewn at Figure 7; this jointed lever carries
clips,, extending the whole width or nearly so, of the movable frame R;
these clips carry spikes z¹, z', which clip the cloth, and hold it while being
folded, as hereafter described; there are two of these jointed levers and camis
arranged so that the clips and spikes alternately hold the cloth during the
to-and-fro motion of the frame.
e is a cam on the shaft Y; f is an eccentric
cam or projection on the lever g, the latter is free to move about the point h,
and is jointed to a long lever i, which is again jointed to another lever:k on
the shaft of the ratchet wheel l, and carrying a paul m. The cam e com-
municates motion to the eccentric cam f; the eccentric cam f throws back the
lever g, which, through the levers i and k communicates motion to the ratchet
wheel, and thence to the pinions V, V, which are mounted on the same
shaft as the ratchet wheel l; n is a spring for keeping the lever g against the
eccentric f; p, p, are guide:rollers for guiding the cloth between the drum and
the bed. The action of the machine is as follows:-The reel carrying the
cloth is placed on. the brackets B; one end of the cloth is led under the
roller H and over the roller H¹ to the drum G, over which it is passed and
brought down to the bed T, which is raised to the position shewn in the
Drawing between the guides S¹, S', under the rollers S, S, where it is caught
between one of the clips z and the upper surface of the table T. The machine
is now set in motion by turning the winch handle M, and the wheel O imme-
diately imparts a to-and-fro motion to the frame R, one clip holding the cloth
while it moves along the bed T. So soon as the frame R reaches the end of
its course, the other clip comes into action and holds the cloth during the
backward motion of the frame, and so on, first in one direction and then in the
other until the whole is folded, the rollers S, S, pressing on the surface of
the cloth to maintain its evenness; at each to-and-fro motion of the frame R
the bed T is caused to descend the extent of one tooth of the ratchet to make
room for the clotb, as it is folded and pressed. This is effected by the cam e
and eccentric f working in conjunction with the cams X', X', so that at each
revolution of the cams X', and consequently at each to-and-fro motion of the
frame R, the cam e presses against the eccentric cam or lever g, which through
the levers i, k, and paul m, causes the ratchet / to move one tooth, which being

page_text: mounted on the same shaft as the pinions V₁, also communicates motion to
them, and consequently to the racks supporting the bed T. The teeth in the
pinions and racks are so arranged that the descent produced by the revolution
of one tooth shall be equal to the depth or space occupied by the thickness of
one layer of cloth. In this way the motion of the machine is kept up until
all the cloth is wound off the reel and laid on the bed T, from whence it is
removed, and the rack and bed are brought back to the position shewn in the
Drawing, ready to commence afresh. The raising of the bed is effected by
throwing the paul out of gear and running the rack up by means of a small
winch connected to the shaft on which the pinions and ratchet are mounted.
When it is required to stamp or mark the cloth as well as fold it, I
pass
between rollers and stamping apparatus as it descends from the drum to the
bed or frame T. U is a supplementary bed or frame, on which cloth which
has not been wound on a reel, as before described, but which is already
creased, is placed to be led from thence over the drum G, and then folded in
the manner before described.
it
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim,―
First, the construction of a saddle and reel for doubling and creasing cloth,
substantially in the manner herein-before described, and illustrated at Figures 1
and 2 of the accompanying Drawings.
Second, the employment of machinery for folding cloth after it has been
creased, constructed and acting substantially in the manner herein-before
described, and illustrated at Figures 3, 4, 5, 6, and 7 of the accompanying
Drawings.
In witness whereof, I, the said Edmund Keogh Dwyer, have hereunto set
my hand and seal, this Twenty-fifth day of April, One thousand eight
hundred and sixty-one.
