page_text: LETTERS PATENT to John Temple, Managing Director of the Warrington Wire
Rope Works, Limited, of Liverpool, in the County of Lancaster, for the Inven-
tion of "IMPROVEMENTS IN THE MODE OF CONSTRUCTING RINGS OR GROMETS
FOR METALLIC CHAIN NETWORK OR NETTING, AND FOR OTHER PURPOSES, AND
IN APPLIANCES THEREFOR."
Scaled the 28th February 1879, and dated the 7th September 1878.
PROVISIONAL SPECIFICATION left by the said John Temple at the Office
of the Commissioners of Patents on the 7th September 1878.
JOHN TEMPLE, Managing Director of the Warrington Wire Rope Works, Limited,
of Liverpool, in the County of Lancaster. "IMPROVEMENTS IN THE MODE OF CON-
STRUCTING RINGS OR GROMETS FOR METALLIC CHAIN NETWORK OR NETTING, AND
FOR OTHER PURPOSES, AND IN APPLIANCES THEREFOR."
My Invention relates to the construction of rings or gromets of flexible wire
nets or netting to be used as guards when fixed to the stanchions round a ships'
deck, or for deep sea fishing or torpedo protecting nets, or for other defensive or
general purposes, and it consists in using wire or other material as a template or
false centre, brazed, tempered, or secured as a single ring for the purpose of working
the stranded rings of wire or gromets upon or over them, and for the purpose of
keeping the rings or gromets of one equal size.
Further, to prevent waste of material I use as a centre or template a spring centre
wire with a hook and eye that can be readily taken out and used over and over
again.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Temple in the Great Seal Patent Office on the 5th March
1879.
JOHN TEMPLE, Managing Director of the Warrington Wire Rope Works, Limited,
of Liverpool, in the County of Lancaster. " IMPROVEMENTS IN THE MODE OF CON-
STRUCTING RINGS OR GROMETS FOR METALLIC CHAIN NETWORK OR NETTING, AND
FOR OTHER PURPOSES, AND IN APPLIANCES THEREFOR."
My Invention relates to the construction of rings or gromets for flexible wire

page_text: nets or netting to be used as guards when fixed to the stanchions round a ship's
deck or for deep sea fishing, torpedo protecting nets, or for other defensive or
general purposes, and it consists in using wire or other material as a template or
false centre brazed or temporarily secured as a single ring for the purpose of
working the stranded rings of wire or gromets upon or over them, and for the
purpose of keeping the rings or groniets of one equal size.
In the Drawings,―
Figs. 1 and 2 show a plan and section of a completed gromet, the Drawings
being made from an actual specimen, full size.
Figs. 3 and 4 are plan and section of template ring used in making said gromet.
The method of manufacture is as follows:-Close the template hook and eye as
shown; then take a piece of wire of about the length required (which can only be
found exactly by actual experiment in the first instance), and twine it round the
template the requisite number of times, twenty-four, in the specimen shown in the
Drawings. By this time the two ends will stick out as shown in dotted lines. The
template is now unhooked and forcibly withdrawn, and can be used to make
other gromets. If this be a trial or first specimen made to this template the two
wires are cut off to such length as to almost fill the space left by the template, and
are inserted into the hole and pressed forward till they fill it. The exact length or
weight of wire used is noted, and this length is cut off for all future gromets, só
as to avoid cutting off the ends made with this template.
'
The template is made of the best tempered steel wire so as to last for a long time
and maintain its form and elasticity.
The exact form of junction for a template is of course immaterial, but I have
found this one to answer best.
Among the advantages of this plan are these, that every gromet is made to the
exact uniform size desired, and consequently an exact length of wire can be cut off
before starting, and thus waste in cuttings is avoided.
Having now described my Invention, and the best mode known to me of carrying
it into effect, I wish it to be understood that what I believe to be new and desire
to protect under the herein-before in part recited Letters Patent is,—
1st. The manufacture, substantially as described, of gromets by the use of a
template of required size, arranged so that it can be opened out from its circular
or other curved form, and withdrawn from the gromet when the twisting is nearly
completed, and yet be made to assume and retain its original form again when
required for use in the manufucture of a fresh gromet.
2nd. The template for the manufacture of gromets, substantially as herein-before
described.
In witness whereof, I, the said John Temple, have hereunto set my hand and
seal, this Twenty-eighth day of February, in the year of our Lord One
thousand eight hundred and seventy-nine.
