IMPROVEMENTS IN WIRE-WORK, APPLICABLE TO THE MANUFACTURE OF SHIPS' ARMOUR, DRIVING BELTS, AND TO OTHER PURPOSES
Year: 1884

page_text: I, GUSTAV PICKHARDT Manufacturer of Hagen, Westphalia in the German
Empire, do hereby declare the nature of said Invention for "IMPROVEMENTS
IN WIRE-WORK, APPLICABLE TO THE MANUFACTURE OF SHIPS' ARMOUR, DRIVING
BELTS, AND TO OTHER PURPOSES," to be as follows:-
The system of wire work or gauze hereinafter described is characterised by the
use of several layers of helical or spiral shaped wires entwined with each other.
The layers of wire may be entwined parallel with each other, or cross-wise, as
represented in the accompanying drawing, in which Figs. I to III illustrate the
principal types.
If double wire is used, the wire work will be correspondingly double.
Fig. I illustrates the parallel spiral shaped wires or springs a b twisted around
each other and entwined parallel with the spiral shaped wires c d which are equally
twisted around each other; the left side of the figure represents a close wire gauze
or fine meshes, while the right side represents wide gauze or coarse meshes, and
which may be subsequently rolled flat.
By rolling this wire-work made of single or double, flat or round spiral shaped
wires of any suitable thickness, and which may have meshes of any suitable size,
a solid, but flexible wire gauze with almost hexagonal mashes may be obtained,
which is suitable for various purposes, especially for replacing wirework usually
made from strong wire by hand. If this wirework consisting of round or flat
spirals is contracted by rolling, a fine, twisted and compact wire-gauze is obtained
suitable for window blinds and various other purposes.
Figs. II and III represent a wire-work consisting of spiral shaped wires
entwined with each-other and arranged cross wise and in several layers.
Driving belts thus constructed may be used for purposes for which belts of
leather or hemp or wire ropes cannot be used.
Such belts may be used for coupling the wheels of locomotive engines in the
place of connecting rods.

third layer arranged parallel with a and which is either only entwined with the
second layer b, or at the same time also with the first layer a; d is the fourth or
bottom layer arranged parallel with the second layer b, and which is entwined with
the third layer c, and with any of the other layers, if desired.
This wire gauze may be used for elastic ships' armour, and for driving belts.
The wire-work may either be used plain, or it may be rolled and filled out with
putty, india rubber, or any other suitable material.

page_text: I, GUSTAV PICKHARDT Manufacturer, of Hagen, Westphalia, in the German,
Empire, do hereby declare the nature of my invention for IMPROVEMENTS IN WIRE-
WORK, APPLICABLE TO THE MANUFACTURE OF SHIPS' ARMOUR, DRIVING BELTS, AND
TO OTHER PURPOSES and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
The system of wire-work or gauze hereinafter described is characterised by the
use of several layers of helical or spiral shaped wires entwined with or screwed
into each other. The layers of wires may be entwined parallel with each other or
crosswise as represented in the drawing filed with the provisional specification in
which Figs I to III illustrate the principal types. If double wire is used the wire-
work will be correspondingly double.
Fig I illustrates the parallel spiral shaped wires or springs a 6 twisted around
each other and entwined parallel with the spiral shaped wires c d which are equally
twisted around each other; the left side of the figure represents a close wire gauze
or fine meshes, while the right side represents wide gauze or coarse meshes and
which may be subsequently rolled flat.
By rolling this wire-work made of single or double flat or round spiral shaped
wires of any suitable thickness and which may have meshes of any suitable size, a
solid, but flexible, wire gauze with almost hexagonal meshes is obtained, which is
suitable for various purposes especially for replacing wire-work usually made from
strong wire by hand. If this wire-work consisting of round or flat spirals is
contracted by rolling, a fine twisted and compact wire gauze is obtained suitable for
window blinds and various other purposes.
Figs II and III represent a wire-work consisting of spiral shaped wires entwined
with each other and arranged crosswise and in several layers.
a is the first or upper layer, b the second layer entwined with the same, c the
third layer arranged parallel with a and which is either only entwined with the
second layer b or at the same time also with the first layer a. d is the fourth or
bottom layer arranged parallel with the second layer b and which is entwined with
the third layer c and with any of the other layers, if desired.
This wire gauze may be used for elastic ships' armour and for driving belts.
The edges of driving belts made of wire-work may be wedge-shaped, and when
used in combination with conical pulleys, considerable adhesion is obtained, such
belts being equally elastic in length, breadth and thickness.
Driving belts thus constructed may be used for purposes for which belts of
leather or hemp or wire ropes cannot be used. Such belts may be used for coupling
the wheels of locomotive engines in the place of connecting rods working on
cranks.
The wire-work may either be used plain, or it may be rolled and filled up with
putty, india-rubber or any other suitable material.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The combination of three or more layers of spiral wire a b c &° connected by
parallel, rectangular or diagonal entwining or screwing together, for the purpose of
making wire-netting or compact wire-work of any dimensions.
2. The method of making solid bodies out of the wire-netting, by filling out
the spirals with putty, india-rubber and other suitable materials, and the
application of the same: 1stly for ships' armour, and 2ndly for endless driving bands
having wedge-shaped edges.
3. The production of flat, compact wire-work by rolling out simple or compound
chain-wire-netting made of round or flat spiral wire.
