PROVISIONAL SPECIFICATION.
Improvements in Apparatus for the Manufacture of Looped Ruchings
or Trimmings.
1, CHARLES GREY HILL, of Arnot Hill, Nottingham, Manufacturer, do hereby
declare the nature of this invention to be as follows:
This invention has for its object Improvements in Apparatus for the Manufacture
of Looped Ruchings or Trimmings.
Goods of this nature are at present produced by the winding of a silk or
other suitable thread or cord or the like, around a screw working in conjunction
with a guide. The loops thus produced are carried forward by the rotation of the
screw and are delivered to pressing rollers which by the aid of a moistened thread
set the loops and attach them to a band.
Now for some descriptions of work the stiffness in the band necessary when the
pressing rollers are used in forming the band, is objectionable.
Besides which it is usually necessary at a subsequent operation to attach an
additional band by the aid of a sewing machine.
To avoid these objections I dispense with the pressing rollers and I combine in
one machine the screw and guide, the winder and sewing instruments which as the
ruching is formed stitch the band in the required position, so completing the work
at one operation.

Improvements in Apparatus for the Manufacture of Looped Ruchings
or Trimmings.
1, 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 :-
This invention has for its object Improvements in Apparatus for the Manufacture
of Looped Ruchings or Trimmings.
Goods of this nature are at present produced by the winding of a silk or other
suitable thread or cord or the like, around a screw working in conjunction with a
guide. The loops thus produced are carried forward by the rotation of the screw
and are delivered to pressing rollers which by the aid of a moistened thread set the
loops and attach them to a band.
Now for some descriptions of work the stiffness in the band necessary when the
pressing rollers are used in forming the band, is objectionable.
Besides which it is usually necessary at a subsequent operation to attach an
additional band by the aid of a sewing machine.
To avoid these objections I dispense with the pressing rollers and I combine in
one machine the screw and guide, the winder and sewing instruments which as the
ruching is formed stitch the band in the required position, so completing the work
at one operation.

page_text: In order that my invention may be fully understood and readily carried into
effect I will proceed to describe the drawings annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a plan and Figure 2 is a side elevation of apparatus in accordance
with my invention.
Figures 3 and 4 show some of the parts separately.
a is a shaft with a spur wheel a¹ upon it; with this wheel a pinion (on a
shaft not shown) gears. The shaft of the pinion receives continuous motion from
a driving belt. a² is a bevelled wheel on the shaft a, it engages a similar wheel b¹
on a hollow shaft or sleeve b which is so caused to rotate in a bearing c.
d is a
stationary support (fixed to one of the standards of the frame) it projects through
the sleeve b, and carries some of the operative parts. The sleeve b is provided
with an arm 6 carrying a bobbin 6 from which in the working of the machine an
ornamental cord or the like is drawn off. is a finger upon the sleeve b, it has an
eye at its extremity to lead the cord.
The parts b, 61, 62, 63, 64, constitute the winder which in revolving lays the
ornamental cord or like material around the screw and guide. e is the screw
and is the guide.
The screw e is formed or fixed at the extremity of a spindle e' which passes
through the sleeve b, it is carried in suitable bearings and has at its end a bevilled
pinion e². The pinion e³ receives movement from a corresponding pinion a³ on the
shaft a.
The guide is stationary but capable of adjustment being attached to the arm or
support d.
g is a flat open tube or passage through which a band of woven fabric
is led into the machine. This band is usually of muslin folded 80 as not to
present raw edges. In Figure 3 the band is marked g' and the ornamental cord
laid around the screw and guide is marked . is the table of a sewing machine,
the band g' passes over its surface and is gradually advanced by the intermittent
rotation of a pair of feed rollers i i which nip the back edge of the band between
them. k is the arm of a sewing machine, that represented in the drawing is of
the Wilcox & Gibbs type. kis the needle slide, it receives movement from a
rocking arm with which at ka an eccentric is connected. The eccentric is upon
a shaft k on which at its extremity is a pinion. An intermediate shaft /* with
bevilled gear transmits movement to the pinion & from the bevilled wheel a* upon
the shaft a. The needle slide k may be furnished with only one sewing machine
needle but for some styles of ruching it is better to employ two needles fixed
upon the same needle slide; provision is made for this in the arrangement shewn.
The needles are in the positions marked k k in Figure 3.
When two needles are
used thread is supplied to them from separate reels at k'. It is necessary also
that there should be two loopers one for each needle. is the ordinary looper ;
as is seen in Figure 4 it is carried at the inner end of the shaft k. is the
second or supplemental looper, it is on a short spinale geared in the manner
shewn in Figures 1 and 4 with the shaft k so that the two loopers rotate
together. Upon the shaft k* also there is an eccentric which by an adjustable
link m gives movement to a rocking lever n.
l
The lever n turns freely upon the shaft of the upper roller i and at n' n' the
lever carries silent feed pawls which engage the periphery of the wheel or disc
the same shaft.
on:
The working of the machine will be readily understood: as the sleeve b revolves
the finger blays the ornamental cord or the like (it may for example be a chenille);
around the screw e and the guide f. The rotation of screw on the one side and the
inclined edge f¹ of the guide on the other carry on the loops of the cord and bring..
them within the range of the needles at
to the fabric band g which is lying on the
beneath. For some patterns of ruchings
which at once sew the loops down on
table of the sewing machine, immediately
one ornamental cord thus sewn upon o

page_text: band suffices but further effects are sometimes advantageously obtained by the
employment of another cord, chenille or the like and provision is made for this in
the machine.
In Figure 3 this supplemental cord is marked o, it may enter the machine through
the sleeve b and be led thence by guides o¹ o' up to the needles at k ke; thus the
cord 6 encloses the cord o in its convolutions. The needles attach both cords to
the band g' and this is moved forward between the stitches at such a rate that its
progress corresponds to that of the loops of the cord or chenille 6 which are
held by the screw.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
―
1. In apparatus for the manufacture of looped ruchings or trimmings, the
combination substantially as described consisting of a screw, a guide, a winder
and sewing instruments; the whole so arranged that the needle catches the loops
formed by the winder and presented by the screw and attaches the loops to a band
through which also the needle passes.
2. Apparatus substantially as herein shown and described.
