PROVISIONAL SPECIFICATION.
Improvements in Skipping Rope and other Handles, and also in the
Production of the said Handles.
I, THOMAS COOPER, of Cheapside, in the City of Birmingham, Foreman of
Works, do hereby declare the nature of this invention to be as follows:-
This invention relates primarily to skipping rope and other handles, and to the
production of the same.
I will first describe my invention in connection with a handle, which is made of
wire, and is fully ventilated. Thus, the handle consists of an open wire worked
one, made up of a series of overlapping and diagonally directed loop coils, or loops
and coils directed from a common and twisted axis.
The edges of the hoops or loops overlap each other alike unto the scales of a
fish, but with the said hoops or loops, which are circular, traversing in a spiral
direction from end to end of the said handle, but spread out in such a manner that
they present a perfectly open worked structure, with the hoops or loops so relatively
disposed, that besides following each other in a spiral order, they follow each other
diagonally, and with the said loops emanating from the backbone or twisted axis,
between which the overlapping loops or hoops are gripped.
The terminal ends of the loops or hoops thus forming the open work handle
are twisted, with the terminals of the wires constituting the principal or primary
axis or backbone.
The handles formed of the said radially disposed loops, overlapping and crossing
each other spirally, may be made conical, or alike in shape to a fir cone, or they
may be made double coned, or they may be made âlike unto a cylinder with parallel
sides.
In carrying out the production of a cone shaped handle, I take a taper mandril
or peg, having a holding hook or notch standing up from its middle, and I closely
wind upon the said taper mandril or peg, a helix, preferably of fine wire.
Then I remove the helix and introduce through the axis thereof a strong wire,
which is then returned upon the outer side of the closely wound coil until the ends
of the wire come together, when the same are united by twisting.
.There is thus produced a closely wound hollow wire helix, threaded upon a long
loop which is held at one end, whilst the other end is rotated, so as to twist the
whole structure upon its own axis.
The twisting of the said long loop makes the one side approach the other, until
they come together and grip one side of the convolutions of the helix between
them. Then by further twisting the said convolutions of the helix (that is, the
hoops or loops), are spread out radially and fan-light, and overlap each other
spirally, and with the brought together and twisted wires forming a central axis or
backbone.
The terminations of the wires may be twisted into eyes or loops to make the
necessary connection to any article as may be desired.
In making the double coned handle, I coil fine wire to form the body of the
handle upon a double coued mandril, divided or hinged about its middle, so as to
admit of the wound double cone being removed.
In the case of a cylinder handle,

Improvements in Skipping Rope and other Handles, and also in the
Production of the said Handles.
I THOMAS COOPER, of Cheapside in the City of Birmingham, Foreman of
Works, 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 primarily to skipping rope and other handles, and to the
production of the same.
I will first describe my invention in connection with a handle, which is made of
wire, and is fully ventilated. Thus, the handle is open wire-worked, and is made
up of a series of overlapping and spirally directed and organized loop coils, or loops
and coils emanating from a common and twisted axis.
The edges of the hoops or loops overlap each other alike unto the scales of a
'fish, but with the said hoops or loops, which are preferably circular, traversing in
a spiral direction from end to end of the said handle, but spread out in such a
manner that they make a perfectly open-worked structure, with the hoops or loops
so relatively disposed that besides following each other in a spiral order, they
follow each other diagonally, and with the said loops emanating from the backbone
. or twisted axis, between which the overlapping loops or hoops are gripped.
The inner presented parts of the loops or spirally disposed convolutions thus
forming the open work handle and also the terminal ends thereof are twisted with
the wires constituting the principal or primary axis or backbone.
The handles formed of the said radially disposed loops overlapping and crossing
each other spirally, may be made conical, or alike in shape to a fir cone, or they
may be made double coned, or they may be made alike unto a cylinder with
parallel sides or they may be made of any other figure as may be desired.
In carrying out the production of a cone shaped handle, I take a taper_mandril
or peg, having a holding hook or notch standing up from its middle, and I closely
wind upon the said taper mandril or peg a helix preferably of fine wire.
Then I remove the helix and introduce through the axis thereof, a strong wire,
which is then returned upon the outer side of the closely wound coil until the ends
of the wire come together, when the same are united by twisting.
There is thus produced a closely wound hollow wire helix, threaded upon a long
loop, which is held at one end, whilst the other end is rotated, so as to twist the
whole structure upon its own axis.
The twisting of the said long loop makes the one side approach the other, until
they come together and grip one side of the convolutions of the helix between
them. Then by further twisting, the said convolutions of the helix (that is, the
hoops or loops) are spread out radially and fan or scale like so as to overlap each
other spirally, and with the brought-together and twisted wires forming a central
axis or backbone.
The terminations of the wires may be twisted into eyes or loops to make the
necessary connection to any article as may be desired.
In making the double coned handle, I coil fine or other wire to form the body of
the handle upon a double coned mandril.
In the case of a cylindrical handle, 1 coil the fine wire upon a mandril having
parallel sides.
Figure 1 of the accompanying drawing represents a ventilated or wire-work
handle constructed and made according to my invention.

page_text: The said wire-work handle consists essentially of a double cone with the parts of
larger diameter meeting in the middle. This said handle, besides being open-
worked or meshed in its constitution has an internal support or backbone of twisted
wire, the twists of which nip the inner parts of the hoops or loops, whose generatrix
proceeds spirally.
÷
Figure 2 represents a hollow double-coned coil of wire the making of which is
the initial process in the production of the handle.
Figure 3 represents the second stage of the production in which the internal
support has one of its legs threaded through the axis of the hollow coil.
Figure 4 represents a transverse section upon the dotted lines A B Figure 3.
Figure 5 represents a part of the hollow and helical cone Figure 2 upon an
enlarged scale, and with some of its coils slightly opened out in order to exhibit its
helical character.
Figure 6 represents the third stage of production showing the figure which the
hollow coil takes on the initial twisting of axial support. The said coil cone first
takes the figure of a snail coiling itself around a stem, and as the twisting proceeds,
so the coils spread or open and then fall scale-like one upon another as hereinafter
more fully described.
In Figure 1, a is the ventilated, reticulated or open wire-work handle, and b is a
central support, strand or hack-bone, between the twists of which, the inner
presented parts of the loops are nipped, and from which they emanate or evolve-
outwardly, radially, spirally and longitudinally as an axis.
In carrying out the manufacture of the said handle Figure 1, I take a mandril or
double taper peg of an outside diameter equal to the inside diameter of the article
to be produced, I close wind fine wire upon the same, which thereby follows and
takes the figure of the peg or mandril, and forms the double coned hollow coil of
wire, shown in Figure 2, and marked c, and having terminal ends c¹.
I then take a length of stouter or thicker wire than the coil and fold the same.
upon itself into a long loop d, having legs d', d². I then pass the leg d², through.
the hollow axis of the cone c, then close the open end of the said long loop d, by
twisting the same into a loop d³, or the like. The ends c¹, of the coil c, are then
twisted around the leg 2, so as to leave no frayed ends and next twist the said long-
loop d, axially upon itself by making fast the one end and then rotating the other
upon its axis. The coil then takes the figure represented in Figure 6, and by
further rotating the loop the convolutions, coils or hoops formulate themselves.
around the said twisted loop d, as a common axis in a longitudinal spiral direction,.
and with the adjacent coils or loops overlapping each other as represented in
Figure 1, thereby forming an open work and ventilated body part with a central
axis or twisted back bone as aforesaid.
The terminations of the axis or back bone may have eyes or loops, or the axes.
inay be prolonged so as to form the shanks or stems of egg-poachers, toasting-forks,.
bill-files, egg-whisks and the like.
The wire to form these handles may be twisted, corrugated or ornamental in any
desired way. The body coils may be made of thicker wire, and the overlapping
lamina-like loops or rings may be united by galvanizing.
Further, to prevent the loops from being pulled up or displaced, the same may
be knitted together by working binding wire therewith.
Figure 7 represents a further form of my invention, in which the handle is made
tubular. In forming the said handle, I form a hollow spiral upon a tubular mandril,
and then submit the same to the same process of twisting as described.
Figure 8 represents a ventilated and open work single coned handle made in
manner alike unto that previously described.
Instead of the loop being made from a single length of wire folded loop wise, it
may be made from two or more lengths of wire or rod, where the central support
or axis is required to be additionally strong, then three or other greater number
may be employed, and further instead of employing wire I may employ thin strip
or band metal or like material.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First. A ventilated or open wire-worked handle, having a central twisted axis,
middle support or backbone, surrounded or partly surrounded by semi-overlapping
or lamina-wise arranged loops, coils or rings emanating from the said axis or back-
bone and evolving themselves outwardly, radially, spirally and longitudinally,
substantially as described and set forth.
Secondly Ventilated or open wire-worked handles constructed, formed or
organized substantiali, as described and set forth.
Thirdly. The production of ventilated or open wire-worked handles as referred
to in the preceding claims, by the means and in the way or ways substantially as
described and set forth.
Fourthly. Forming ventilated or open wire-worked handles from hollow coils of
wire by twisting and nipping the same between two or more thick wire or rod
