page_text: I, CHARLES GREY HILL of Arnot Hill in the County of Nottingham, Manufacturer,
do hereby declare the nature of this invention to be as follows:-
The apparatus is designed to produce a scolloped frilling with deep indentations by
gathering the fabric inwards at intervals towards its centre line.
The apparatus is provided with a revolving, drum which is partly surrounded by a
curved plate. The fabric to be operated upon is fed in as a band between the plate
and drum at a greater speed than that of the drum so as to provide for the material
taken up by the scollops or the fabric may be previously gathered together by a
separate machine and be fed in at the same speed as the drum. The surface of the
drum has in it a number of grooves parallel to its axis and in these grooves there are
blades or formers. As the drum revolves the ends of these formers come towards eacli
other in pairs almost meeting each other midway of the length of the drum, squeezing
the fabric together between them. A wetted or gummed thread or threads is then
pressed down by a roller upon the fabric and so retains its shape. The necessary
inward and outward motions are given to the formers by cam surfaces. Normally the
formers lie completely in the grooves but just before they come into operation their
outer ends come against springs and are depressed and their inner ends are elevated
as far as the curved plate around the drum permits. As soon as the fabric comes to
the nip of the drum and roller the formers are no longer required to hold it and their
outer ends are therefore released and their inner ends are forced back again into the
grooves by the roller.

page_text: I, CHARLES GREY HILL, of Arnot Hill, in the County of Nottingham, Manufacturer,
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:-
The apparatus is designed to produce a scolloped frilling with deep indentations by
gathering the fabric inwards at intervals towards its centre line.
The apparatus is provided with a revolving drum which is partly surrounded by a
curved plate. The fabric to be operated upon is fed in as a band between the plate
and drum at a greater speed than that of the drum so as to provide for the material
taken up by the scollops or the fabric may be previously gathered together by a
separate machine and be fed in at the same speed as the drum; this latter method is
preferable. The surface of the drum has in it a number of grooves parallel to its axis
and in these grooves there are blades or formers. As the drum revolves the ends of
these formers come towards each other in pairs also meeting each other midway of the
length of the drum, squeezing the fabric together between them. A wetted or
gummed thread or threads is then pressed down by a roller upon the fabric and so
retains its shape. The necessary inward and outward motions are given to the formers
by cam surfaces. Normally the formers lie completely in the grooves but just before
they come into operation their outer ends come against springs and are depressed and
their inner ends are elevated as far as the curved plate around the drum permits. As
soon as the fabric comes to the nip of the drum and roller the formers are no longer
required to hold it and their outer ends are therefore released and their inner ends are
forced back again into the grooves by the roller.
In order that my said invention may be fully understood and readily carried into
effect I will proceed to describe the drawings hereunto annexed.
Figure 1 is a front elevation and Figure 2 is a transverse vertical section of
apparatus made in accordance with my invention.
Figure 3 shows the fabric as it is passed into the machine and
Figure 4 shows the fabric after it has been scolloped by the operation of the machine
upon it.
Figure 5 shows a detail.
a a is a frame
is a metal cylinder mounted in bearings on the frame; it is
caused to rotate continuously by suitable driving gear and it is heated by gas flames

page_text: burning within it. c is a narrow roller carried in bearings which are able to slide
vertically in grooves in the frame its periphery is in contact with the cylinder 6 and
it is pressed down by springs adjustable by screws. This roller is also heated by gas
flames. The cylinder bis grooved and the formers e e are carried in the grooves-two
formers in each groove. Figure 5 shows one of the formers e. f is a cover plate bent
to the curve of the cylinder and surrounding it; this plate is carried by the frame it
is not in contact with the cylinder but there is a narrow space into which the band of
fabric is received. ggare cam rings or surfaces fixed to the frame, the formers are
notched at to receive them. These rings cause the formers to traverse in the
grooves as the cylinder revolves. hh are spring feet mounted on the frame which
during part of the rotation of the cylinder press against the outer ends of the sliders
and thereby tilt them so that their other ends come to bear against the inner surface
of the cover plate. ii are guards which ensure that the formers do not project from
the grooves at the place where these guards are situate. kis a fixed guide mouth by
which the fabric to be operated upon is passed into the machine. I prefer to feed the
machine with bands of fabric previously pleated and retained by a thread pressed on
with rollers in the usual way. Often two or more such bands are fed in together one
over the other; the attendant taking care to keep them properly superposed. I can
employ a crimped fabric and provide a mechanical feeder upon the guide mouth which
crowds the fabric in so as to accumulate it in pleats but it is better to pleat the fabric
previously.
The band or bands of fabric are carried forward upon the face of the cylinder b
beneath the plate which keeps the fabric in place and the formers e then approach
from either side with their ends raised into contact with the plate so that they may
catch with certainty the edges of the fabric bands and they press these inwards
towards the centre and hold the fabric between them. Then by the rotation of the
cylinder the fabric in this form is carried beneath the narrow roller c. The formers
pass beneath the roller and descend into their grooves as it presses upon them. A
moist cotton is also led from a bobbin 7 beneath the roller c, the heat causes the cotton
to adhere and the fabric becomes held permanently in the shape given to it by thə
formers.
The scolloped band still upon the face of the cylinder passes round with the cylinder
and is drawn off by hand from the under side.
After coming from the machine the scolloped frilling is usually divided longi-
tudinally (along the track of the roller c) and is made up by hand as may be
required.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. Apparatus substantially as described for the manufacture of frilling and consisting
of a rotating cylinder or travelling surface supporting the band of fabric; a cover
plate serving to keep the fabric in place on the drum or surface; formers moving in
grooves in the cylinder or surface and displacing the edges of the fabric whilst it is so
held; and a roller or presser operating to set the band of fabric in the shape which it
is made to assume by the formers.
2. Apparatus substantially as described for the manufacture of frilling and consisting
of a travelling surface supporting the band of fabric; a cover plate serving to keep
the fabric in place on the surface; formers entering the space between the surface and
the plate and displacing the edge of the fabric thereby producing scollops and a roller
or presser operating to set the band of fabric in the shape it is made to assume by the
formers.
3. In apparatus substantially as described for the manufacture of frilling the
combination consisting of the cylinder the cover plate and the formers e such
formers being arranged to move in slots in the cylinder and where operating to rise
into contact with the cover plate.

page_text: 4. In apparatus substantially as described for the manufacture of frilling the
combination consisting of the cylinder the cover plate f the formers e and the
pressing roller such formers being arranged to move in slots in the cylinder and
where operating to rise into contact with the cover plate and then whilst holding
the fabric between them to descend into their slots to allow the pressing roller to pass
over them.
