ROBERT L. HORSLEY, OF FORT WORTH, TEXAS, ASSIGNOR TO WORTH WIRE WORKS, A
CORPORATION OF TEXAS.
WIRE-COILING MACHINE.Specification of Letters Patent.
Application filed March 2, 1906. Serial No. 303,884. Renewed Tuly 24, 1907. Serial No, 385,314.
To all whom it may concern:
Be it known that I, ROBERT L. HORSLEY, a citizen
of the United States, residing at Fort Worth, Texas,
have invented a new and Improved Wire-Coiling
5 Machine, of which the following is a specification.
This invention relates to machines for manufactur-
ing wire coil, and the object is to provide machines
for working wire of different temper and of different
sizes and coiling the same into coils which are ellip-
10 tical in cross section and which are adapted for the
manufacture of such articles as door mats and the like.
Other objects and advantages will be fully explained
in the following description and the invention will be
more fully pointed out in the claims.
15 Reference is had to the accompanying drawings
which form a part of this application and specification.
Figure 1 is a side elevation of the machine. Fig. 2
is a horizontal section of the machine taken on the
line :-z of Fig. 1. Fig. 3 is a cross section of the
20 forming blade or former taken on the line y-y of
Fig. 2.
Similar characters of reference are used to indicate
the same parts throughout the several views.
This machine is mounted on any suitable support
25 or platform 1. The machine has a frame 2 which
may be bolted to the support 1. A cylindrical casing
3 forms the upper part of the machine. A feeder 4 is
mounted in the casing 3 rigidly by means of a set
screw 5. The feeder 4 may be set at different adjust-
30 ments by loosening the set screw 5 and moving the
feeder to the desired adjustment. This may be done
to bring the feeder and the former 9 into proper opera-
tive relation. The former terminates with a cylin-
drical portion or shaft 6 which is threaded near the
35 end. This former moves freely in the feeder 4 and is
held in place by the nut 8 and the jam-nut 7. The
nuts 7 and 8 hold the former 9 against displacement
by reason of the wire passing through the feeder 4,
the tendency being to draw the former in the direc-
40 tion of the moving coil. The former 9 is driven by
the pulley 10. The pulley 10 is movable axially on
the rod or shaft 6 and a key 15, which is rigid in the
rod 6, moves in a slot 16 in the pulley 10. A wire 11
is fed to the machine from any suitable supply source.
15 An adjustable guide 12 for directing the wire to the
machine is mounted in the frame 2. The guide 12 is
made adjustable by a nut 17 which may be screwed
further on or further off of the end of the guide 12.
The feeder 4 consists of a tube having a spiral slot cut
50 therein for receiving and feeding the wire, or which
takes the wire coil from the former 9. The spiral slot
may be cut out larger or flared at the point where it
receives the wire 11 so that the edge of the slot will
not shear the wire. The wire is directed and drawn
55 by the slot in the tube and the flight of the coil ispartly determined by the spiral feeder. The former
consists of a blade 9 and the spindle portion or rod 6.
The blade 9 is twisted approximately 45 degrees at
the point 13. The twisted portion of the blade ter-
minates in slight grooves 14 diagonally across the 60
blade on opposite sides thereof so that a cross section
of the former 9 on the line y- will show a form or
appearance as illustrated in Fig. 3. This is done to
- take away the rounded portion caused by twisting and
to provide a flat surface for forming the sides of coils. 65
The object of twisting the former blade is to adapt
the blade to operate on wire of different temper and
of different sizes. The twist of the former is at the
point where the wire enters the spiral feeder and the
major part of the twist does not enter the coil that is 70
being formed. Means are provided for adjusting the
former so that more or less of the twist can be let into
the coil that is being formed. This is necessary for
operating on wire of different sizes and of different
temper. With small wire more of the twist must 75
enter the coil, as small wire is more elastic than large
wire. Also with hard wire more of the twist must
enter the coil because hard wire is more elastic than
soft wire. The coil manufactured by such machine
as is herein described has two substantially flat sides 80
and these flat sides are substantially opposite the flat
sides of the former during manufacture of the coil,
and the object of the twist at the starting point is that
the wire may be bent far enough beyond the plane of
the coil already formed so that the rebound of the 85
wire will be just sufficient to bring the flat part of
the coil being formed in the plane of the coil already
formed. There is a short'bend of the wire on each
side of the coil and these short bends of the wire are
formed on and engage the edges of the former. These 90
bends are made uniform by the edges of the former
so that the flat side of each flight of the coil when
completed.will be in the same plane as the flat sides
of the coil already formed, and the edges or short
bends of the wire will continue in the same straight 95
lines. Thus the coil will be flat from end to end
with no twists therein, however long the coil may be.
Having fully described my invention, what I
claim as new and desire to secure by Letters Patent,
is,- 100
1. A wire coiling machine comprising a spiral feeder
and.a former rotating in said feeder, said former consist-
ing of a blade twisted substantially one eighth and the
twisted portion extending a distance substantially only
one flight of the spiral feeder and said twisted portion be- 105
ing opposite the receiving portion of said feeder.
2. A wire coiling machine comprising a spiral feeder
and a former rotating in said feeder, said former consist-
ing of a blade twisted only at the receiving portion of said
feeder, a part of said twisted portion entering in the coil 110
being formed.
1 3. A wire coiling machine comprising a spiral feederNo. 870,514.
