de la Chausée d'Antin, Paris, France, & 90, Cannon Street, in the City of London,
Patent Agent. "IMPROVEMENTS IN THE MANUFACTURE OF ELASTIC SPIRAL
STEEL-WIRE ROPES, AND APPARATUS CONNECTED THEREWITH." A communication
from Anton Jarolimek, of Hainburg, in the Empire of Austria.
The Invention relates to the manufacture from steel wire, tempered beforehand,
and annealed to the required degree, of spiral springs of any length whatever
determined only by the length of the wire; the use of the said spiral springs as
elastic steel ropes for transmission, traction, and other purposes, and their
substitution for leather belts, thongs, ropes, or cords of different materials now in
use, and the apparatus for the manufacture of the said elastic steel-wire ropes, and
even spiral springs from any metallic wire, whatever its length may be.
This apparatus consists of a shaft, mounted upon two bearings and entirely
hollow, so as to allow the spiral spring being manufactured and its core to pass
through it. To one of the ends of this shaft two jaws, provided with a thumb-
screw, are adjusted to keep the spiral spring and its core immoveable in and united
with the hollow shaft during the rotation of the latter. A loose pulley is keyed
upon this hollow shaft, operated by a belt, which by means of a friction-coupling
or other contrivance imparts a rotary motion to the shaft, and which may be
uncoupled at pleasure by means of a coupling or uncoupling apparatus whatever.

page_text: The steel-wire being wound upon a bobbin placed at the side and in front of
the apparatus, one of its ends for the length of a few centimetres is wound by hand
upon the end of a central core or rod one or more metres in length. A rotary
motion is imparted by means of the pulley and driving belt to the hollow shaft,
and at the same time to the core and the part of wire already wound upon it, and
the steel wire is wound from the bobbin around the core, being pressed against it
with a thick piece of leather or by a little plank held and sustained by the hand.
When the steel-wire is wound up to the other end of the core the jaws are loosened
by unscrewing the thumb-screw; the wire wound up is then slid through the
hollow shaft, the core and the last portion of steel wiro wound upon it are again
fixed as before by means of the jaws and the thumbscrew, and the operation is thus
continued to the end of the steel-wire.

IMPROVEMENTS IN THE MANUFACTURE OF ELASTIC SPIRAL
STEEL WIRE ROPES, AND APPARATUS CONNECTED THEREWITH." A communication
from Anton Jarolimek, of Hainburg, in the Empire of Austria.
The Invention relates to the manufacture from steel wire, tempered beforehand
and annealed to the required degree, of spiral springs of any length whatever,
determined only by the length of the wire; the use of the said spiral springs as
elastic steel ropes for transmission, traction, and other purposes, and their
substitution for leather belts, thongs, ropes, or cords of different materials now in
use, and the apparatus for the manufacture of the said elastic steel wire ropes, and
even spiral springs from any metallic wire, whatever its length may be.
This apparatus consists of a shaft, mounted upon two bearings and entiroly
hollow, so as to allow the spiral spring being manufactured and its coro to pass
through it. To one of the ends of this shaft two jaws, provided with a thumb-
screw, are adjusted to keep the spiral spring and its core immoveable in and united
with the hollow shaft during the rotation of the latter. A looso pulley is keyed
upon this hollow shaft operated by a belt, which by means of a friction coupling
or other contrivance imparts a rotary motion to the shaft, and which may be
uncoupled at pleasure by means of a coupling or uncoupling apparatus whatever.
The steel wire being wound upon a bobbin placed at the side and in front of
the apparatus, one of its ends for the length of a few centimetres is wound by hand
upon the end of a central core or rod one or more metres in length. A rotary
motion is imparted by means of the pulley and driving belt to the hollow shaft,
and at the same time to the core and the part of wire already wound upon it, and
the steel wire is wound from the bobbin around the core, being pressed against it
with a thick piece of leather or by a little plank held and sustained by the hand.
When the steel wire is wound up to the other end of the core the jaws are loosened
by unscrewing the thumb-screw; the wire wound up is then slid through the
hollow shaft, the core and the last portion of steel wire wound upon it are again
fixed as before by means of the jaws and the thumb-screw, and the operation is
thus continued to the end of the steel wire.
After having briefly described the said Invention I shall now do so more
particularly by referring to the accompanying Drawings,―
A is the hollow shaft; B, the two bearings; C, the wound up steel wire; D, the
jaws; E, the thumbscrew; F, the loose pulley; G, the friction coupling; H, the
coupling apparatus; I, the core or rod; J, the metallic wire; K, the piece of
leather or little plank.
As above stated, the said elastic steel ropes may be made by means of this
apparatus of any desired length, determined only by the length of the metallic
wire, of whatever kind it be, for it may be used for wires other than previously
tempered steel wire, the same as springs may be made with previously tempered
steel wire by means of any other suitable apparatus, provided care is taken that its
hardness be such as not to break.
When a short spring or rope is manufactured, C, which turns during the rotation
of the shaft, may bear on the ground or be received in some recipient, but when
the springs or ropes are long the finished part is wound upon a bobbin, put in
motion by the spring if of sufficient rigidity, or by the engine.
The said elastic steel ropes may be used like leather belts, thongs, ropes, or

page_text: cords of different materials. They cost less and last very long, and suffer to obtain
an elastic transmission without jerking. In proportioning the diameter of the
metallic wire with that of the rope it is to form, these ropes or belts may be used
for different purposes; for instance, when great forces are to be transmitted and
flexibility is not required, a strong wire wound upon a small core perfectly
accomplishes its design, while a wire of very small diameter wound upon a stronger
core may be used for the transmission of weaker forces.
The said ropes are employed such as they have been manufactured, placed side
by side, or they may be stretched beforehand by one half, and even once or twice
their length, their resistance to tractive force being thus greatly increased, but at
the loss of flexibility.
To be substituted for driving belts and metallic wire cables these ropes are
placed in greater or less number, according to the use they are intended for, side
by side upon a pair of grooved pullies, and the two ends of each rope are either
screwed into one another, especially for relatively large ropes, by screwing into
both ends a spring of a less diameter, or by inserting thereinto a suitable india-rubber
plug; but in all cases, before screwing on, the second end ought to be unrolled a
number of spires equal to the number of spires held by the plug, so that the rope
after being joined-may-not tend to unroll itself. A similar joining never undoes
itself, is hardly visible, nor is any knot found at the place. To increase the friction
between the rope and the pulley the groove of the latter ought, by preference, to
be as usual, wedge shaped, and into which the ropes are solidly-fitted. Under the
said arrangement cast-iron, wooden,-or- iron-pullies_covered_with_wood or any
other suitable material may be used.
By increasing the elasticity of these ropes by a proper choico as to their diameter,
the loss of transmissive power from slipping upon the pullies by driving belts is
avoided. When greater resistances are necessary the said ropes may be made with
two or more wires in juxtaposition, whilst for uses where ordinary ropes are
employed these elastic spiral ropes may be made with untempered steel, drawn
stiff and hard, or with brass wire.
Having thus described the said Invention and the manner of carrying it into
effect, I claim,
1°. The manufacture from steel wire, previously tempered and annealed, of spiral
springs of any longth, determined only by the length of the wire, as substantially
above described.
2º. The apparatus for manufacturing the said elastic steel wire springs from steel
wire, tempered and annealed beforehand, consisting substantially of a hollow shaft
provided with jaws through which the finished spring passes, and, to which a
rotatory motion is imparted, as described above and shown in the accompanying
Drawings.
3°. The substitution of spiral springs manufactured from steel wire, previously
tempered and annealed, to leather driving belts or belts of other materials, thongs,
ropes, or cords, for transmission or traction, as above stated.
In witness whereof, I, the said Henri Adrien Bonneville, have hereunto set my
hand and seal, this Sixth day of December, in the year of our Lord One
thousand eight hundred and eighty.
