Improvements in Metallic Rings or Links Applicable for Use in the
Manufacture of Chain Network or Netting.
I, JOHN TEMPLE, Managing Director, Warrington Wire Rope Works, Limited, of
Liverpool in the County of Lancaster, do hereby declare the nature of this invention
to be as follows:-
The object of this invention is to provide a strong and durable ring or link, and is
chiefly designed for use in the manufacture of flexible wire nets or netting such as are
used for torpedo protecting nets, and other purposes. The ring may however be put
to other uses where metallic rings or links are employed.
In
In the construction of these nets or netting of wire it is desirable to obtain the
greatest amount of strength without increase of weight, and by the use of my
improved ring or link for the same weight of metal, I get an increase of strength.
The rings at present in use are welded rings made from iron or steel, which are
heavy and weak from the welding. I designed others made as coils or spirals
of three four or more turns placed side by side, but when subjected to considerable
strain the spirals are apt to break, one at a time, and thus finally give way.
carrying out my present invention however, I place the spirals of wire so as to
support or sustain one another, so that one spiral shall not have more strain upon it
than another and consequently no breakage will occur until the strain is sufficient to
break the entire ring. I make the ring or link of a double or multiple series of spirals,
I coil two, three, four or more spirals of the wire upon a mandril or spindle, and on
top of those, coil a number of spirals, and so on, one on top of the other, according
to the thickness and strength of ring required. This may be easily done on a mandril,
with a collar or shoulder, against which the wire as it coils comes in contact, and is
caused to coil back again on top of the first spiral; where more than a double spiral
is required, a second shoulder on the mandril may be used. When the spiral is com-
pleted a chisel or shears actuated by hand or by power will cut off the wire.

I, JOHN TEMPLE, Managing Director, Warrington Wire Rope Works Limited, of
Liverpool, in the County of Lancaster, 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:-

Referring to the drawing.
Figure I is a section of my improved ring.
Figure II is a front elevation.
Figure III is an elevation of a hand machine on the spindle of which I wind my
improved ring.
Figure IV is an end elevation of the spindle with the ring wound on it.
I make the ring or link A of a double or multiple series of spirals. I coil two
three or more spirals a of the wire upon a mandril or spindle B B and on the top of
these coil a number of spirals al and so on, one on the top of the other according to
the thickness and strength of the ring required. This may be easily done on the
mandril with a collar or shoulder B¹ against which the wire as it coils comes in contact
and is caused to coil back again on to the top of the first spiral; where more than a
double spiral is required a second shoulder on the mandril may be used. When the
spiral is completed a chisel or shears actuated by hand or by power will cut off the

page_text: wire. I may also use a machine worked by steam power in which an automatic
arrangement is provided for cutting off the wire. The links when made are galvanized
to increase their strength.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed I declare that what I claim is :—
A ring made of metal wire preferably iron or steel coiled in the manner substantially
