CHARLES JACKSON, of the town and county of the town of Nottingham,
"IMPROVEMENTS IN MACHINERY AND APPARATUS TO BE EMPLOYED IN THE
PRODUCTION OF ORNAMENTAL FRILLINGS,"
The machinery and apparatus consists of the following parts. A bed plate to
which is secured a pair of vertical standards which form bearings for a gas heated
brass roller, and carry adjustable bearings for a metal presser roller, above the brass
one, these rollers can be forcibly presse together by means of set screws, springs
and lock nuts; behind the brass roller is a pair of flanged brass gas heated rollers,
also provided at their bearings with screws, springs and lock nuts.
In front of the first named rollers the standards carry bearings connected by a
plate, which slides to and fro in a grooved bed, secured to the standards, the
sliding bearings carry two double excentric shafts, each of which alternately operate
a frame sliding in bearings and carrying a pair of blades, each frame is knuckle
butt jointed.
The excentric shafts revolve the reverse way to each other, by means of toothe.l
gearing, one shaft being provided with a fast and loose pulley and fly wheel at one
end, and at the opposite end gearing to drive the first named rollers the speed
required. Beneath the excentric shafts in front of the first named rollers are
guides each of which carry a stud or truck traversed by a grooved pattern roller.
In addition to the above, I employ guard blades and rollers, guiding endless
bands of asbestos thread, and instead of covering the pressing roller with calico or
linen, I cover it with asbestos cloth. By means of a machine constructed as above
described, I am enabled to produce scolloped or vandyked or other shaped edges
required in frillings and also to produce either plain or box pleated frillings in great
variety.

The machinery and apparatus consists of the following parts, a bed plate to
which is secured a pair of vertical standards which form bearings for a gas heated
brass roller, and carry adjustable bearings for a metal presser roller above the brass
one these rollers can be forcibly pressed together by means of set screws springs

two double eccentric shafts each of which alternately operate a frame sliding in
bearings, and carrying a pair of blades, each frame is knuckle butt jointed.
The eccentric shafts revolve the reverse way to each other by means of toothed
gearing, one shaft being provided with a fast and loose pulley and fly wheel at one
end, and at the opposite end gearing to drive the first named rollers the speed
required. Beneath the eccentric shafts in front of the first named rollers are
guides, each of which carry a stud or truck traversed by a grooved pattern roller.
In addition to the above I employ guard blades, and rollers guiding endless
bands of asbestos thread, and instead of covering the pressing roller, with calico or
linen, I cover it with asbestos cloth. By means of a machine constructed as above
described I am enabled to produce scolloped or vandyked or other shaped edges
required in frillings and also produce either plain, or box pleated frillings in great
Figure 1 is a left side elevation of a pleating machine constructed according to
my invention, with some parts removed
Figure 2 is a right side elevation of the same machine with part of a cam
removed
Figure 3 is a plan of the machine with part of a cam removed
Figures 4. 5 and 6 are portions of the machine shewn separately.
The corresponding parts in each Figure are lettered alike where necessary
My improved machinery and apparatus consists of the following parts, a bed
plate to which is secured a pair of vertical standards A, which form bearings for a
gas heated brass roller B, and carry adjustable bearings for a gas heated metal
presser roller C above the brass one; either or both of these rollers I cover with
asbestos cloth instead of with calico or linen.
These rollers can be forcibly pressed together by means of set screws, springs
and lock nuts shewn in the two elevations, behind the brass roller is a flanged
brass gas heated roller D, also provided at its bearings with screws, springs and
lock nuts. The pipes to supply gas for heating the several rollers, are not shewn
in the drawings, but may be any usual convenient form which will afford a
sufficient supply of a mixture of gas and air to the rollers. In front of the rollers B
and C a grooved bed E is secured to the standards, upon this bed a plate E' slides
to and fro and is provided with and connects two bearings E2 in which a bearing
rocks which is T shaped at each end, which form bearings carrying two double

page_text: eccentric shafts E³, E³, each of which alternately operate a frame F, which is slotted
and capable of adjustment by means of screws and wing nuts (shewn in Figure 3).
on a cross bar, the ends of which form axles, which take into, and rock in bearings
which slide in slotted bearing brackets F', secured to the inside of the standards,
each frame F is knuckle butt jointed and carries a blade F2 which has slits in one
side in the usual way. The eccentric shafts revolve the reverse way to each other
by means of toothed gearing arranged as follows:-The double T shaped bearing
between the two double eccentric shafts carries a driving shaft G which projects
beyond the T bearing at the right of the machine, where it has a toothed wheel G₁
secured on it, this wheel gears into a similar toothed wheel E' on the inner upper
eccentric shaft which carries a larger toothed' wheel E5 on its left end which gears
into a similar toothed wheel, on the inner lower eccentric shaft, by such means the
simultaneous revolution of both double eccentrics are effected, outside the wheel G¹,
the driving shaft is provided with a fast and loose pulley and fly wheel, and carries
on its left end a worm which actuates a worm wheel H upon an inclined axis
which also carries a worm H¹ which drives a worm wheel H2 on the axis of the
gas heated roller B (this gearing is seen in the side elevation Figure 1). The right
end of the axis of the roller B carries a toothed wheel gearing into a similar wheel
on the axis of the presser roller C thus causing both rollers to revolve simul-
taneously. The toothed wheel on the right end of the axis of the roller B gears
into a similar intermediate toothed wheel, shewn by dotted lines at Figure 2
(this intermediate wheel is only used when the frame Foperated by the lower
double eccentric, is not employed) the machine then only pleats the fabric supplied
to it one way, at such time when required, a grooved pattern roller I carried in a
bearing bracket is secured to the inside of the standards (portion of this bracket
only is shewn at Figure 2) an end of this bracket is seen at Figure 4, carrying
the axis of the grooved pattern roller, which lies between the bearings, the axis
projects at the right end through the right standard, and carries a toothed wheel
twice the diameter of the toothed wheel on the axis of the roller B, which revolves
twice or as may be required to one revolution of the grooved pattern roller (the
grooved surface of this roller is seen spread out flat at Figure 5) in the groove
a truck or roller is traversed to the right or left, the axis of the truck being
secured in the underside of a plate I' sliding in a bed formed in the upper side of
the bearing bracket the sliding plate, has a guide 12 secured on the top, through
this guide the fabric to be pleated is passed. By such means any pattern of
scallop, vandyke or curves, may be produced on each edge of the pleated fabric
according to the pattern set out on the roller.
The double eccentrics E being each adjusted to give the same length of throw
one pleating blade will form pleats the reverse way to the pleats formed by the
other pleating blade. The rocking of the T shaped bearings carrying the double
eccentrics is effected by toothed gearing in the following manner:-The toothed
wheel G on the right end of the driving shaft G gears into teeth cut on the
circumference of a cam J seen partly in side view at Figures 1 and 2; and
partly in plan at Figure 3, an inner side view is seen separately at Figure 6. The
cam is grooved to receive a truck carried by a stud in the outer end of a connecting
link J', which slides in a bearing projecting from a standard secured to the bed
plate of the machine, and carrying the cam axle, the inner end of the link J¹ rocks
on the projecting right end of the axis of the lower double eccentric E³ seen in
Figure 2, holding the lower pleating blade frame at its half backward throw, and
the upper double eccentric, holding the upper pleating blade frame at its half
forward throw. The cam shewn is set out to hold the upper eccentric in towards
the pressing rollers while the upper blade makes three pleats, it is then drawn
back at the same time as the lower eccentric is moved in, while the lower blade
makes three pleats the reverse way to the upper blade and the movements, are
repeated. The depth of the pleats are adjusted by altering the throw of the double
eccentrics, and the number of pleats each blade makes is governed by the pattern
cam employed

page_text: In addition to covering the pressing rollers with asbestos cloth I employ two
series of freely revolving rollers K round which endless bands or threads K', are
passed, said bands or threads also passing round the pressing rollers, any number
of these endless bands or threads may be employed on each side the centre of the
fabric to be pleated, the pleated fabric lying between such bands or threads is held
in position until set or otherwise dealt with and is thus delivered from between
the sets of bands or threads of asbestos in a perfect form. Thus by the employment
of asbestos to cover the rollers, and asbestos bands or threads to guide the pleated
fabric from the pressing rollers, I am enabled to drive the machine much quicker
than heretofore by employing greater heat, which the asbestos resists
Having thus described the nature of my said Invention, and the manner of
performing the same, I declare that I Claim.
First. I claim the employment of asbestos for covering rollers, and bands or
threads of asbestos for guiding and holding pleatings, gopherings or frillings of any
material in the form required, substantially as described.
Second. The construction and employment of a cam to govern pleating blades
to produce a variety of reversely pleated fabrics substantially as described
Third. The knuckle butt jointed frames, carrying the pleating blades, substantially
as described
In Witness whereof I the said Charles Jackson have hereunto set my hand
and seal this Twenty eighth day of March in the year of our Lord One
thousand eight hundred and eighty three.
