Improvements in Apparatus for Coiling Wire and Weaving Coiled
Wire Fabric.
We, MARSHALL BURNS LLOYD and CLARENCE OTIS WHITE, Manufacturers,
both of 315 3rd Avenue S., in the City of Minneapolis, County of Hennepin, State of
Minnesota, United States of America, do hereby declare the nature of our inven-
tion 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 improvements in machines designed for coiling wire and
weaving the same into fabric, and the invention consists generally in an improved
coiler by means of which two wires may be coiled independently of each other and
projected so as to run parallel with each other throughout their entire length, each
part of the coiler being capable of independent adjustment for the purpose of
regulating the pitch and length of coil in each of the wires independently of the
other.
The invention further consists in an improved reel for holding the wire, and in
the constructions and combinations hereinafter described and particularly pointed
out in the claims and will be more readily understood by reference to the accom-
panying drawings, in which:
Figure 1 is a general plan view of a wire coiling machine constructed in
accordance with our invention and showing our improved coiler and reels in
operative position thereon.
Figure 2 is a side elevation of this machine.
Figures 3 and 4 are details.
Figure 5 is a front elevation of the coiler.
Figures 6 and 7 are details thereof.
Figures 8 and 9 are details of the reel.
2 represents the frame of the machine which may be of any suitable construction,
and is preferably supported upon suitable legs 3. Mounted in suitable standards 5
at the end of the machine is the driving shaft 7 which is preferably provided with
suitable fast and loose pulleys 9 and 11. This end of the machine is preferably
designated as the "head." A second shaft 13 is arranged above and parallel with
the shaft 7, and this shaft is mounted in movable blocks or boxes 15, see Figure 3,
supported in the standards 5, and the two shafts are driven simultaneously. Each
of said shafts is provided with a wire feeding roll 19, and suitable adjusting
screws 21 are provided for the purpose of adjusting the rolls so as to regulate the
pressure upon the wire passing between them. The upper shaft 13 is held at one
end by a suitable tension spring. A shaft 23 is mounted in bearings in the
standard 5, and is provided with a cam projection that comes directly under the
block 15 at the end of the shaft that is provided with the roll 19. The shaft 7 is
provided with a suitable friction roll 25 and a countershaft 27 is mounted in
bearings at the head of the machine and carries a friction driving wheel 29 that is
in contact with the wheel 25 upon the shaft 7. The shaft 23 is provided with a
crank arm 31, see Figure 2, that is in engagement with a cam 33 Figure 1 upon
the shaft 27. A rod 35 engages the said crank arm 31 and this rod is connected at
its lower end to a spring 37 having its upper end secured to the frame of the
machine. This spring tends to hold the arm at all times in engagement with the
cam 33. The cam is provided with a surface that is adapted to permit said arm to
be depressed by the spring at the requisite intervals and thereby the upper shaft 13
is slightly raised so as to separate the feed rolls 19 and thus permit the movement
of the wire to cease.
The wire for forming the fabric is supported upon suitable reels suspended from

page_text: the frame of the machine. These reels consist of the hollow tubes 51 near the
lower end of which are the plates 53, said plates and tubes being secured to the
frame of the machine by the inclined brace rods 55. The upper ends of said brace
rods are fastened to the plate 57, Figure 9, and this plate slips over the lugs 59
that are secured on the underside of the frame 2 of the machine. By this means
the reels may be readily removed from the machine for the purpose of placing new
coils of wire thereon. Below the plate 53, the tube 51 is provided with the flaring
mouth-piece 61 above which is the rotatable wire guide 63. This guide is pre-
ferably formed of a strip of wire coiled around the upper part of the mouth-piece 61,
its outer end being bent up into substantially the plane of the plate 63 and provided
with an eye through which the wire from the reel passes. The wire being placed
upon the reel, its end is carried through the eye in the guide arm 63 into the
mouth-piece 61 and up through the interior of the tube 51. After leaving the
tube 51 it passes over suitable guide rolls 65, by means of which the wire from both
reels is directed to the coiler and through a suitable guide-tube 67, Figure 5, and
between the feed rolls 19. From the feed rolls the wire passes through the coiler
hereinafter described, from which it is projected in the form of suitable spirals, as
will be explained. Before describing the coiler proper we will describe the
mechanism for receiving the wire after it passes from the coiler.
The wires after passing from the coiler enter a receiver 71, consisting of a
rectangular tube extending the full length of the machine and having an open top.
This receiver is mounted upon suitable stationary supports upon the frame of the
machine and is preferably located in line with the coiler so that as the wire passes
from the coiler it enters this receiver and passes along therein. Arranged in this
receiver is a longitudinally-sliding plate 75 provided with a series of pins 77 against
which the wire coils are brought as they pass through the receiver. The spirals in
the wire are of such length that as the wire passes through the receiver its forward
end is brought into contact with the first pin on the side farthest from the coiler
and as it passes this pin considerable friction is applied thereto, which exerts
tension or pull on the wire, tending to stretch it between the pin and the coiler. A
similar action occurs as the end of the wire strikes the next piu and so on
throughout the receiver, as the wire strikes and passes each pin its tension upon the
preceding pin is released and thus the tension or pull is exerted between the coiler
and the pin at the advancing end of the wire, while the wire is practically free
from the other pin. After each coil of wire is run into the receiver and thereby
interlocked with the last preceding coil in the fabric, the plate 75 is moved longi-
tudinally in the receiver for the purpose of moving the final coil into longitudinal
position to receive the next or incoming coil.
For the purpose of holding the final coil in the receiver while the incoming wire
is being inserted, we provide a plate 93, Figure 4, secured upon the tube 71 so as
to slide thereon and adapted to be moved forward so as to partially cover the open
top of the receiver. This plate is provided with a hevelled forward edge and is
adapted to project into the space between the last coil and the next to the last coil,
and thus hold the last coil of the fabric rigidly in position in the receiver for the
incoming coil to be interlocked therewith. This plate is connected by a rod 95
Figure 1 to a rock-shaft 97. Said shaft being provided with an arm 99 to which is
secured a connecting rod 101 and a spring 103. Said rod is provided with a slot
through which passes the shaft 107 provided with a cam 109, and said rod is pro-
vided with a roll 111 that engages said cam. As the shaft 107 is rotated, the cam
and the spring give to the shaft 97 the necessary rocking movement to advance
and withdraw the plate 93 as required. For the purpose of controlling the move-
ment of the fabric and thereby permitting the proper movement to bring the final
coil into position to receive the incoming coil, we provide an escapement device
consisting of a yoke 113, Figure 4, that is arranged to be reciprocated by the
arm 115 on a rocket shaft 117. Said shaft is given a rocking movement by means
of an arm 119 secured thereon and a connecting rod 121 pivotally connected to the
end of said arm and to the face of the pinion 89 in an eccentric position. The

page_text: yoke 113 is provided with the upright plates 123, which carry the two series of
pins 125. These pins when the yoke is at one extreme of its movement engage
the fabric from one side, and when the yoke is moved to the other extreme of its
movement, the fabric released by the pins upon this side and is engaged by the
pins from the other side. Between the time when one set of pins releases the
fabric and the other set engages it, the fabric is permitted to be moved a distance
equal to the diameter of one coil, thereby bringing the final coil into such position
in the receiver that the next or incoming coil will engage therewith. The fabric
passes from the receiver over a bar 127 having a curved upper surface, and then
passes over a windlass 129, Figure 4, having a series of spurs in its surface. This
windlass is mounted in standards 131, secured upon the frame of the machine and
is adapted to be operated by hand or otherwise. The fabric is preferably allowed
to hang down between the frame of the machine and the windlass 129 and a suitable
weight 133 is preferably placed thereon, this weight serving to draw the fabric
over each time that the knife edge of the plate 93 is drawn back and the fabric is
released by the escapement. For the purpose of cutting off the wire after the
insertion of each coil we preferably provide the swinging knife 135 Figure 1 con-
nected to the sliding rod 137. This rod is connected to the cam 139 upon
the shaft 27 and operated thereby to cut the wire at the proper intervals of
time.
From this
The wire coiler is shown on a larger scale in Figures 5, 6 and 7. The wire from
the reels passes through the guide 67 and between the feed rolls, and then through the
grooved guide 143 which is provided with the removable top plate 145.
guide the wires pass into the separate coiling barrels 147. Each of said barrels is
provided with a spiral groove and is surrounded by a loose sleeve 149, said sleeve
being free to rotate around the barrel and being rotated by the friction of the wire
passing through the groove in the barrel. At the front end of the barrel is a
conical adjuster 151 secured to the barrel so as to be capable of being moved
therewith. An arm 153 is connected to this conical adjuster and its lower end is
connected to a stud 155 that passes through a slot 157 in a plate 159. A thumb
nut 161 is provided upon this stud and by means thereof the coiler and the adjuster
may be moved so as to properly adjust the coils parallel with each other.
barrel is provided with a journal 163 upon its end, that is mounted in a block 165
and is held in position by means of suitable set screws 167. By loosening these
set screws the barrels may be adjusted towards or from the block and thereby the
coils may be adjusted relatively to the receiver herein before referred to. By means
of the conical adjuster the pitch of the coils may be varied at will.
A special
advantage is obtained from this construction of coiler, as by adjusting the parts
of the coiler independently the spirals of the wire may be varied at pleasure,
being either lengthened or shortened, and they may be laid exactly parallel with
each other so that when they enter the receiver they will lie close together and be
similarly acted upon by the pins as they pass through the receiver.
The
Instead of supporting the reel upon the frame of the machine, as shown in
Figures 1 and 2, it may, if preferred, be constructed as shown in Figure 8, wherein
the reel is supported upon an independent frame, and the guide arm is in the form
of a curved tube 175 pivotally supported upon the lower end of the tube con-
stituting the axes of the reel. This form of reel is preferable where it is desired
to work heavy wire.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. The wire-holding reel, provided with the tubular centre, and the rotating
guiding arm, and arranged to feed the wire up through said tubular centre,
substantially as described.
2. The wire-holding reel having the tubular centre, the rotating guiding arm,
and means for suspending the reel from its upper end, substantially as described.

page_text: 3. The coiler, having the two independent barrels arranged parallel with each
other, and the feed rolls for driving the wire through both barrels simultaneously,
substantially as described.
4. The wire coiler, having the two independent barrels arranged parallel with
each other, and means for independently adjusting either part of the coiler,
substantially as described.
5. The combination, with the coiler, provided with the two independent barrels
arranged parallel with each other, of the feed rolls, and the receiver provided with
the series of pins and arranged to receive the wires from both parts of the coiler,
substantially as described.
