Improvements in Machines for Making Coiled Springs and for
Winding Wire upon Flexible Hose and other Articles.
I, FREDERICK MARTEN HALE, of The Sphincter Grip Armoured Hose Company
Limited, 63 Fore Street, City of London, Secretary, do hereby declare the nature
of this invention to be as follows:-
This invention relates to certain arrangement of appliances constituting a machine
for winding or coiling continuous cylindrical spiral springs or wire, and is especially
adapted to coiling such springs or wire around pipes, tubes, or rods, or where the
use of a mandril is objectionable.
In this machine the wire is forced by nipping or friction rollers (which draw
the wire from a supply reel) into a spirally grooved block or screw nut, so that
the wire assumes a fixed spiral form agreeing with the grooves of the block, the
spiral grooves sustaining the entire pressure necessary to bend the wire into position,
and so permitting the wire to be coiled around soft or yielding substances without
danger of undue compression.
This hollow screw block or grooved nut is mounted as hereafter particularly
described so as to form part of or revolve with the hollow axis of a revolving disc or
wheel upon the flat sides of which are mounted the necessary feed and nipping rollers
in order to supply wire to the central grooved nut and force it in as coiling progresses.
A supply of wire is carried by a reel or rim on the edge of the wheel, the whole
apparatus revolving with the disc, and the various parts having additional connected
motions.
The arrangement is as follows:-
A wheel or disc is bolted to a main hollow axis or journal, to which suitable trains
of gear are attached to effect revolution of the wheel. The pipe, hose, or tube to be
coiled with wire, is by the operation of coiling drawn through the hollow journal,
suitable let off and take up reels being adjusted to assist this if necessary with heavy
tubing.
On the periphery of the wheel or disc is the wire supply reel or rim forming a
circular tyre held to the wheel by a friction ring adjustable for tension by the screws.
By this friction grip, the rim revolves with the wheel, but by regulating the tension,
it is capable of an independent revolving movement as the wire is drawn off and
consumed in forming the springs. The rim consists essentially of a circular gutter or
holder for the wire.
From the rim the wire is led to and around a guide pulley whence the wire passes
and is drawn between two nipping rollers mounted on the wheel or disc so as to be
carried with it. The rollers have a series of corresponding pairs of grooves on their
surfaces for adjustment for use with different sizes of wire. An independent revolving
movement is given to the rollers by a "sun and planet" gear movement, its axis of
revolution agreeing with that of the hollow journal. The planet gear is mounted on a
shaft which is cased in a journal passing through the disc, the other end of the shaft
bearing one of the nipping rollers. The second nipping roller has its shaft mounted
in a sliding adjustable box, by means of which the pressure upon the wire and the
distance between the rollers is regulated, so that different sizes of wire may be used.
A screw adjustment and a tension spring allow of variations in working. A box is
mounted in a frame or head centered on the shaft or axis of the friction roller, so as
to be movable around it, on loosening the retaining nut. By this means the wire is
fed out of the rollers at any desired angle. Adjustable guide tubes are employed
for the wire mounted on the head. The friction rollers revolve by motion com-
municated from the shaft by the gear. In order to avoid jamming from any
irregular movement caused by a crooked shaft, or otherwise, the shaft of the upper
Paine R71

page_text: friction roller is mounted in boxes which turn on pins or studs fitting into the frame
or head.
The groove block or screw nut or die by which the wire is guided and coiled into
a spiral round the tube, hose, or pipe, is. formed on or fastened to the end of a
separable removable cylindrical tube which is made separable so as to permit different
sizes of wires to be used in the same machine, it being necessary only to alter and
remove the tube with its screw die end and substitute another. These cylindrical
tubes are of the same diameter, and fit into a hollow sleeve or receptacle fastened to
and projecting from the disc over and in line with the hollow journal, which sleeve is
split so as to permit of being tightened by suitable screws to hold the tube in place.
This permits the up and down adjustment of the tube in its receptacle so that the
entering groove in the screw block or die can be made to correspond with any pair
of the grooves in the surfaces of the nipping rollers, so that the wire is fed in a direct
line.

Improvements in Machines for Making Coiled Springs and for
Winding Wire upon Flexible Hose and other Articles.
I, FREDERICK MARTEN HALE, of The Sphincter Grip Armoured Hose Company,
Limited, 63 Fore Street, City of London, Secretary, 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 certain arrangement of appliances constituting a machine
for winding or coiling continuous cylindrical spiral springs or wire around pipes tubes
or rods, or where the use of a mandril is objectionable.
In this machine the wire is forced by nipping or friction rollers (which draw the
wire from a supply reel) into a spirally grooved block or screw nut, so that the wire
assumes a fixed spiral form agreeing with the grooves of the block, the spiral
grooves sustaining the entire pressure necessary to bend the wire into position, and
so permitting the wire to be coiled round soft or yielding substances without danger of
undue compression.
This hollow screw block or grooved nut is mounted as hereafter particularly
described, so as to form part of or revolve with the hollow axis of a revolving disc
or wheel, upon the flat sides of which are mounted the necessary feed and nipping
rollers in order to supply wire to the central grooved nut and force it in as coiling
progresses. A supply of wire is carried by a reel or rim on the edge of the wheel,
the whole apparatus revolving with the disc, and the various parts having additional
connected motions.
By reference to the drawings forming part of this Specification, these parts are
more easily understood.
Figure 1 is a face and Figure 2 a sectional or side view.
A is the wheel or disc bolted to the main hollow axis or journal B, to which
suitable trains of gear are attached to effect revolution of the wheel. The pipe, hose
or tube to be coiled with wire is by the operation of coiling drawn through the
hollow journal B, suitable let off and take up reels being adjusted to assist this, if
necessary, with heavy tubing.
On the periphery of the wheel or disc is the wire supply reel or rim C forming a
circular tyre held to the wheel by a friction ring D, adjustable for tension by the
screws E, E, E, E. By this friction grip, the rim C revolves with the wheel, but
by regulating the tension, it is capable of an independent revolving movement as the
wire is drawn off and consumed. The rim C consists essentially of a circular gutter
or holder for the wire.
From the rim C, the wire is led to and around a guide pulley F, whence the wire

page_text: passes and is drawn between two nipping rollers G, G¹, mounted on the wheel or
disc, so as to be carried with it. The rollers have a series of corresponding pairs of
grooves on their surfaces for adjustment for use with different sizes of wire. An
independent revolving movement is given to the rollers by a "sun and planet" gear
movement, the stationary gear H being bolted to the machine main frame, its axis
of revolution agreeing with that of the hollow journal B, and the planet gear I being
mounted on the shaft K which is cased in a journal passing through the disc A, the
other end of the shaft bearing one of the nipping rollers G². The second nipping
roller G has its shaft mounted in a sliding adjustable box L, by means of which, the
pressure upon the wire and the distance between the rollers regulated, so that
different sizes of wire may be used. The box L has a screw adjustment and also a
tension spring to allow of variations in working. The box L is mounted in a frame
or head M centred on the shaft or axis K of the friction roller G¹, so as to be movable
around it, on loosening the retaining nut N. By this means, the wire is fed out of
the rollers at any desired angle. Adjustable guide tubes O, O, are employed for the
wire, mounted on the head M. The friction rollers revolve by motion communicated
from the shaft K by the gear P, Pl. In order to avoid jamming from any irregular
movement caused by a crooked shaft, or otherwise the shaft of the upper friction
roller G is mounted in boxes which turn on pins or studs R, R, fitting into the
frame or head M.
The groove block or screw nut or die by which the wire is guided and coiled into
a spiral round the tube, hose, or pipe, is formed on or fastened to the end of a separable
removable cylindrical tube, which is made separable, so as to permit different sizes
of springs to be made and tubes to be wire armoured by the same machine, it being
necessary only to alter and remove the tube with its screw die end and substitute
another. These cylindrical tubes are of the same diameter, and fit into a hollow
sleeve or receptacle S fastened to and projecting from the disc A over and in line
with the hollow journal B, which sleeve is split at T, so as to permit of being
tightened by suitable screws to hold the tube in place. This permits the up and
down adjustment of the tube in its receptacle, so that the entering groove in the
screw block or die can be made to correspond with any pair of the grooves
in the surfaces of the nipping rollers G, G¹³, so that the wire is fed in a direct
line.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
