I, ALFRED HERBERT DAVIES of Little John Villa, 152 Robin Hood's Chase, in
the Town and County of the Town of Nottingham Civil and Consulting Engineer
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to construct a machine for spotting veilings or
plain nets or the securing to the bars of the plain fabric and at required intervals
a small portion of chenille in such manner as to have the appearance of a spot
upon the fabric.
In order to describe my invention I will divide it into two parts; first the head
which feeds in the required length of chenille, cuts off, loops it, delivers on a bar
of the net, closes up the loop and complets the formation of the spot. The other
part I will call the work-frame, this carries the work or material to be operated
upon, which at proper intervals is moved about according to the pitch or distri-
bution of the spots to be attached to the plain fabric.
The head consists of two parts which may be termed the back and front portions,
one is on one face of the fabric and the other on the opposite, and the fabric free
to be moved upwards and shogged laterally as may be required.
The working parts of each of these heads are fixed on the top side of angle plates,
while the vertical sides of the angles extend downwards with sufficient space
between to allow them to act as guide faces for the fabric.
On one side of the fabric the chenille is fed up, the required length cut off,
looped and delivered on to a bar of the same, this portion I will call the 'looper.'
On the other side of the fabric the open ends of the loop so delivered are closed,
and then compressed in the hollow or recessed end of the looper' feed 'bar on the
looper side of the head by a bar similarily formed on this side of head, and
the spot thus completed and secured to the fabric. These bars now retreat, and the
fabric is moved to receive the next course of spots.
The 'looper' portion of the head comprises a spindle or shaft suitably supported
and having imparted thereto a rotary motion from other revolving part of the
machine.
Cams of various shapes in order to impart either directly or otherwise the several
motions and times required to form and deliver the loop upon a ban of the net
or veiling are fixed on this shaft.
The operation of this part of the machine is as follows:
The chenille is fed from a reel or straight length through a guide having
tubular ends with an open space or trough betwen in which the feed brush works.
This feed brush or serrated foot, but preferably a brush, is attached to the feed
bar to which is imparted a reciprocating horizontal movement of the required
length from a cam fixed to the cam shaft; this feed bar works in suitable guides
fixed to the head. The nose of the guide is immediately over the cutting edge
of a knife plate fixed on the top side of the angle plate.
The feed brush has in addition to the horizontal movement mentioned a vertical

page_text: movement obtained from a cam on cam shaft through a lever suitably fulcrumed
to part of head; one end of this lever carries the truck or bowl that rides on the
cam, and the opposite end is widened out and takes between two pins or lugs on the
back side of the vertical brush bar.
The object of this right angled motion to the feed brush is to depress the brush
on the chenille when feeling up and at the end of the feed and when the knife
has cut, to lift it up clear of the same and to keep it clear during its return for the
next motion. This is effected by the lever aforementioned which is caused to lift
up the brush at the end of the feed by raising the top pin on the brush bar, and
the end of the lever being widened it keeps the brush bar up during the return of
the feed bar, to be again depressed by the lever acting upon the lower pin at the
proper time for the succeeding motion. The brush thus describing or moving
through a parallelogram.
Just before the chenille is fed up, a vertical bar carried in the head and receiving
its motion from a cam on the cam shaft and provided with a pin having an
elongated flat end which is secured in the bottom enul of said bar, the pin being
terined the former' and its bar the 'former-bar' is caused to descend to the face
of the angle plate. The chenille is fed up at the back of this former and before
the knife hereinafter described-cuts off, or the feel brush lifts from the chenille,
a horizontal bar at right angles with the former bar and in the same line and
termed the centre nose or loop feed bar moves forward and the nose of the same
which is slightly concave holds the chenille up to the back of the 'former.' A
vertical knife bar also carried in the head and receiving its motion from a can
on cam shaft through a rocking shaft and levers now descends and cuts off the
chenille fed up. The centre nose or loop feed bar and the former bar now
remain at rest until the looper' proper moves forward and bends the chenille
round the sides of the 'former,' the centre nose bar then cases back a little to
enable the former' to lift clear of the looper.' It then advances and pushes
the loop or row U shaped piece of chenille out of the 'looper' and on to a bar of
the veiling or net.
On the other side of the fabric and fixed on the top face of a similar angle
plate is a bracket carrying a cam shaft closing levers and presser lar.
When the loop is delivered on a bar of the fabric as described, the nose ends of
two levers or legs suitably fulcrumed and actuated from a cam on the cam shaft,
close in and cross the open ends of the loop, they then immediately open and the,
'presser bar also actuated from a cam on cam shaft, and suitably concaved at the
end moves forward and presses the chenille to the centre nose or loop feed har.
These two bars remain stationary until the closing' levers and presser bar
have done their work or completed the spot; they now retreat and are given an
interval of rest, during which the fabric is made to alter its position vertically and
laterally as required for the next course of spots.
The work fame or the part which carries the veiling or net to be spotted, and
that which is finished, rides upon bars secured to the fraune of the machine.
The plain fabric is first carefully straightened out in layers and placed on a
platform with adjustable sides for the purpose of keeping the fabric quite straight,
this platform is suspended from liars which are free to move laterally as required
on the bars which are fixed to the carcase or frame of machine. The material is
then conducted partly round a roller and upwards between the work faces of the
angle plates of the head hereinbefore described, and over a roller fixed above,
porcupine wheels or bands are employed on these rollers in order to keep the
fabric accurately distended. The rollers are connected by means of a chain and
chain wheels or ratchet wheels, so as to receive a simultaneous movement which
racks the fabric upwards. The fabric then slopes downwards passing over an
examining plate, which preferably consists of an enamelled plate and of a colour
suitable to clearly shew up any defects in the spotting, so that the attendant can
readily rectify them by hand. The fabric then passes on to a second platform
suspended in similar manner to the one described but on the other side of machine.

page_text: The lateral movement to the work-frame is obtained from a cam and a counter
cam through lovers suitably fulcrumed and fixed conveniently to the machine
frame and acting at each end of the work-frame.
The various cam and other shafts for the performance of the above described
motions are driven in equal times so that one revolution of the same completes a
spot or row of spots and moves the work frame and fabric for the succeeding row.
A series of heads are fixed to the angle plates of the machine and their distance
apart adjusted to the nature of the work required.
The first motion shaft is supported in bearings conveniently fixed to the
machine frame.

I ALFRED HERBERT DAVIES, of Little John Villa, Robin Hood's Chase, in the
City of Nottingham. Civil and Consulting Engineer, 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 relates to apparatus for automatically attaching what are termed
spots of chenille or like materials to lace veilings or nets at the required points,
and thus proxlucing what is known as spotted veilings.
The invention will be best understood by reference to the accompanying draw-
ings in which
Fig. 1. is a vertical cross section
Fig. 2. a front elevation, and
Fig. 3. a plan of a machine constructed according to my invention
Fig. 4. is a side elevation partly in section

Fig. 6. a rear elevation, of one of the heads for cutting and looping the chenille.
Fig. 7. is a cross section, and
Fig. 8. a plan showing the formation of the net rollers
Fig. 9. is a view of a piece of net with which the teeth of the roller shown are
adapted to mesh.
Figs. 10, 11, 12, 13 and 14 are sectional plans illustrating the operation of the
inachine.
Fig. 15. is a side elevation of the cam for reciprocating the work frame.
Figs. 4. to 15. inclusive are drawn to a larger scale than Figs 1, 2 and 3.
Like letters indicate like parts throughout the drawings.
In carrying out this invention the machine may be said to comprise two main
parts, that is a work fname for holding the net whilst the spots are applied thereto,
and mechanism for forming the chenille or like spots and attaching them to the
net,in rows.
The work frame is also adapted to feed the net forward the required distance
after each row of spots has been applied, and also to move the net laterally in
order that the spots may be applied thereto in diagonal lines, as well as horizontal
and vertical lines.
The work frame (see Figs. 1, 2 and 3.) is formed by two transverse end plates or
framings AA connected together by longitudinal stays A'A' A'. The fram-
ings AA are mounted on two longitudinal-fixed-shafts-B-B-secured to the main

page_text: standards BB of the machine, and thd said frames A A may be moved laterally
on the shafts B B.
Mounted in bearings secured to or formed in the lower part of the framings A A
are two rollers CC, at the upper part of the said framing and mounted in the same
manner as the rollers CC are two corresponding rollers CC³. The net D passes
between the two rollers CC and is then carried up vertically and over the two
rollers CC, it is then carried over a plate A which may be enamelled any colour
which will show up faults in the net or spots.
In order that the net D may be advanced the exact distance required each
movement, and also be held perfectly tight between the roller CC the latter are
porcupine or toothed rollers, and the teeth of the said rollers are so formed and
distributed that they will mesh with the interstices of the not.
For example Figs. 7. and 8. show a toothed roller, the teeth C of which are so
shaped and disposed that they will mesh correctly with the interstices in the net
shown at Fig. 9.
It will be understood that the form and disposition of the teeth of the rollers CC
will be different for nets with different meshies.
The net D is advanced by rotating the rollers CC simultaneously, and for this
purpose the said rollers are formed with extended spindles C (see Figs. 2.
and 3.) on which latter are mounted toothed wheels F. F. the teeth of which mesh
with each other. The bosses of the wheels FF are mounted in bearings F' F¹
secured to the standards B' and the spindles C7 C7 of the rollers are free to move
longitudinally in the bosses of the wheels FF in order that the rollers may he
moved laterally with the framings A. A.
The rotary motion of each of the wheels F F is communicated to its respective
spindle by means of a feather key in the one engaging with a key-way in the
other.
Secured to the lower wheel F is a rack wheel F which is operated by a pawl F³,
this pawl is pivotted on a lever which is connected by a link to a cam
lever provided with an antifriction roller in peripheral contact with a cam
on the main cam shaft G. The latter is carried in bearing G G secured to or
formed in the main standards B¹.
The framings A. A and the whole of the mechanism connected therewith which
together comprises the work frame, is moved laterally as required by a bell-
crunk lever H (see Fig. 2.) pivotted to an extension 1 of the framing B. The
upper end of the lover I engages with a pin H on the lower longitudinal stay A¹
whilst its lower end is connected by a link H2 to a cam lever H provided with
an antifriction roller in engagement with a cam H. The cam H is mounted on
a shaft H carried in bearings H6 secured to or formed in the standrads B, and
said shaft is connected to the main cam shaft G by toothed wheels H'H'.
In Fig. 15. is shown a cam H which is adapted to reciprocate the work frame
to and fro as required when the spots in one horizontal row are to be in the same
position vertically as the spaces in the preceeding row.
Instead of the plain rollers CC I may employ circular brushes, or rollers with
helical ribs to push the net D down to the roots of the teeth C in the rollers CC².
The mechanism for fesling the chenille or other material, cutting it off, forming
it into loops, and delivering said loops on to the net comprises a number of heads.
which are identical in construction and are operated simultaneously, each one
making a loop of chenille and delivering it on to the net at a point between the
rollers CC³.
The whole of the heads J are carried and are adjustable longitudinally on a
bar J of the section shown which is secured to the end standards B', B', the base
of each head J being formed by a bracket J which is clamped on to the said bar
by a screw J.
Each head is provided with a chenille feed, a cutter to cut off a length of
chenille, a former, a looper to bend the chenille round the former, and an ejector
to eject the loop from the looper.

page_text: The feed (see Figs. 4, 5 and 6.) is formed by two rollers LL the former of
which is provided with a groove to receive the cheuille. This roller L is mounted
on one end of a bell-crank lever L pivotted to the side of the bracket J* so that
the roller L may be apaised to insert the chenille in the groove.
The roller L is provided with a roughened surface and is secured on the end
of a shaft L mounted in a bearing in the bracket J. The chenille M which is
brought down from the spool M and between the rollers LL' is intermittently
advanced the required extent, by rotating the roller L. This is effected by a
rack wheel L on the rear end of the shaft L2 which is advanced by a pawl L
pivotted on a longitudinally reciprocating bar L.
The end of the chenille M is fed forward on to a platform N in front of the
bracket J between the former N and the end of the looper N, as shown in
Fig. 10. This portion of the chenille is then cut off by a cutter N (see Fig. 5.)
secured to the end of the lever N. The former N is also, mounted on the end of
the lever N but as its end is lower than the edge of the cutter, it passes the
chenille before a length is cut off and thus retains it in position after the latter
process is coupleted.
The looner N, which is formed by a bar sliding in the bracket J and is pro-
vided with a slotted end, now advances and bends the chenille round the former N¹
as shown in Fig. 12., the former N is now raised and the loop ejected from the
looper on to a bar of the net by the ejector N as shown in Fig. 12. The ejector N°
is mounted in and slides within the looper N3.
The levers Nou the whole of the heads (see Figs. 1. and 3.) are each connected
by a link O to an arm O on the rocking shaft 03. The loopers N2 are each con-
nected by a link to an arm 0 on the rocking shaft 05 and each of the
ejectors N are connected by a link 06 to an arm 07 on the rocking shaft 08.
The rocking shafts 02, 0 and 08, are carried in bearings 0 secured to the
bar J, and each is operated by a separate cam l' on the main cam shaft G through
a cam lever 1" fulcrummed on the fixed shaft Ps and connected by a link 13 to an
arm on each of the said shafts.
On the opposite side of the net 1) to the heads J are a corresponding number
of instruments for closing the loops of chenille on the net.
These instruments are carried by brackets I which are clamped on and are
adjusted on a bar R' of the section shown which is secured to the main standards B'.
Pivotted on the upper face of each bracket It is a pair of jaws I, (see Figs. 2.
and 3.) these jaws are all simultaneously opened and closed by a longitudinal
bar It one jaw of each pair being connected to said bar at the point 1 and the
other jaw of each pair at the point 1. When the bar R3 is moved longitudinally
in one direction the corresponding jaws in each pair are moved in one direction
and the other jaws in the reverse direction and they are thus opened or closed
by a single movement of the bar R³.
The bar R³ is moved longitudinally by a bell-crank lever S (see Fig 2) pivotted
to the har 1 its upper end being directly connected to the bar 13 and its lower
end connected by a link S to a cam lever S2 operated by a cam S3 on the main
cam shaft G.
On the underside of each pair of jaws It is a sliding ram T each mounted in
the corresponding bracket R. The outer end of each ram T is connected by a
link T to an arm T on the rocking shaft To, which latter is mounted in bear-
ings T secured to the bar R.
Tlie rocking shift T is connected by an arm T and link T to a' cam lever T
fulcrumed on the fixed shaft P2 operated by a cam T on the main cam shaft G.
When the ejector No has ejected the loop of chenille from the looper N on to a
bar of the net D, the two free ends of each loop are closed by the corresponding
jaws R³ as shown in Fig. 13. the jaws T3 then open and the ram T advances and
the loops are pressed between the ejectors N5 and the rum T as shown in Fig. 14.
The net is then moved and a fresh succession of loops are formed, delivered,
and fixed on to the net, in the manner described.

page_text: The bar L for operating the pawls L is reciprocated by an arrangement
(which is not shown) similar to that shown for reciprocating the bar R³.
