PROVISIONAL SPECIFICATION.
Improvements in Apparatus for the Manufacture of Frilling
I, CHARLES GREY HILL, of Arnot Hill Nottingham, Manufacturer, do hereby declare
the nature of this invention to be as follows:-
In the Specification of a Patent granted to me dated the 14th day of December
1887, No. 17234 I described a machine for producing a scolloped frilling with deep
indentations formed by gathering a band of fabric inwards at intervals towards its
centre line. According to. that specification the indentations were produced by.
formers whose ends came against the edge of the band and pressed it inwards. When
operating upon very thin fabric this machine is apt to tear it.
According to this invention. I serrate one side of the formers and I provide a cam
surface by which the serrated sides are raised into contact with the fabric just before
the formers are moved inwards to produce the indentations the fabric being held
across its width between the formers and the plate whilst the indentations are being
made.

COMPLETE SPECIFICATION.
Improvements in Apparatus for the Manufacture of Frilling.
I, CHARLES GREY. HILL, of Arnot Hill, 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:
In the Specification of a Patent granted to me dated the 14th day of December 1887,
No. 17234, I described a machine for producing a scolloped frilling, with deep inden-
tations formed by gathering a band of fabric inwards at intervals towards its centre
line. According to that Specification the indentations were produced by formers whose
ends came against the edge of the band and pressed' it inwards. When operating
upon very thin fabric this machine is apt to tear it.
According to this invention I serrate one side of the formers and 1, provide a cam
surface by which the serrated sides are raised into contact with the fabric, just before
the formers are moved to produce the indentations, the fabric being held across
its width between the formers and the plate whilst the indentations are being
made.
In order that, my said invention may be fully understood and readily carried
into effect I'will proceed to describe the drawings liereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation with some of the parts removed of a machine constructed
in accordance with my invention.
Figure 2 is a section on the line 2, 2, in Figure 1:
a is the main axis, on it are pulleys to receive a driving belt, is another axis
geared with a as, shown and on this, there, is, an ordinary, crimping roller & working
with an upper. crimping, roller on, an axis c.. The band,of, fabric enters. the machine
between these rollers and is crimped by them. I prefer that these crimping, rollers
should form part of the machine but it is not essential as the band of fabric may
be brought to: the machine already. crimped! The band of fabric may be of various
[Price 8a.]

page_text: widths but such as is shown at Figure 3 is suitable and the band may be double or
single. A spur wheel on the axis 6 by means of pinions as shown drives another spur
wheel on an axis d. There are finely serrated dises d' d' on the axis d, they project
down through slots in the stationary plate e. The plate e partly surrounds and is
nearly in contact with the surface of the drum f. This drum is driven by gearing as
shown from the axis through intermediate wheels gg.
The band of crimped fabric after leaving the crimping rollers on the axes b and c
enters between the plate e and the surface of the drum and is crowded forward by the
discs dd which revolve at a higher speed than the drum into the narrow space
between the periphery of the drum and the inner surface of the plate e. The band of
fabric is carried round by the drum as it revolves and whilst on the face of the drum
it is arranged by formers as will immediately be more fully described. is a roller
revolving in contact with the drum over it threads i (which are more or less moist)
are led.
These threads are pressed by the roller h against the fabric and they adhere
to it and keep it in form. The machine is heated by gas as is usual in the use of
frilling machines. At a short distance from the roller the plate e terminates and
the frilling falls away from the drum and is received into a basket or otherwise.
Figure is a diagram showing approximately the form in which the frilling leaves the
machine.
I will now describe the mechanism by which the band of fabric is arranged whilst
it is upon the drum.
The drum with the parts more immediately in connection therewith are symmetrical
on the two sides of the machine. In Figure 1 one side is shown complete; on the
other side some parts are omitted or broken off in order that others may be more
clearly seen. The drum has on its periphery a series of grooves parallel to the axis
and in these grooves the formers k k are able to slide longitudinally. One of the formers
is shown separately about full size at Figure 5. Each former has a projection k¹ upon
one of its ends and the formers are so arranged that these projections are alternately
towards the right side and the left side of the machine. The formers are held in the
grooves of the drum by two rings (one only is shown). The rings are made in
segments and fixed by tap screws on to the drum. The formers being divided into two
sets, right and left, the projections of each set are received between two rings 17 carried
by brackets from the frame and between the rings there is a parallel guide course just
sufficiently wide for the projections to travel round freely. The guide course is
oblique in parts and the form is such as to impart to the formers the amount of end wise
movement which is required. The endwise movement of each former commences soon
after it reaches the top of the drum and is completed in somewhat less than one quarter
of a rotation. The formers of one set move to the right and those of the other set to
the left. The formers are brought back by the guide courses as they rise on the
hinder side of the drum.
The formers have ratchet like teeth upon them and these teeth are intended to
engage with the band of fabric so that when the former is moved longitudinally it
carries the fabric sideways with it. Just as this movement of the formers commences
they are lifted slightly so that the fabric becomes nipped slightly between the teeth
and the inner surface of the plate e. The lifting of the formers in the grooves of the
drum is effected by stationary cam plates m m upon which the ends of the formers
rest. m' m' are raised surfaces on the edges of these cam plates. In place of carrying
the formers upon a drum it is obvious that they may be mounted on an endless chain
carrier but the arrangement described is preferable.
The patterns of frilling may be varied by altering the relative speeds of the discs d'
and the drum f; by altering the movements of the formers; by altering the width
of the band of fabric and by other like means.
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. In apparatus for the manufacture of frilling; a drum or travelling surface with

page_text: formers upon it to which a transverse movement is imparted; such formers being
serrated on the sides and made to nip the band of fabric between their serrated surfaces
and a plate set at a short distance from the face of the drum or travelling surface as
herein set forth.
2. Apparatus for the manufacture of frilling substantially as herein described.
