Year: 1867

page_text: LETTERS PATENT to Achille Edward Gelhaye, of Windmill Road, Croydon,
in the County of Surrey, Engineer, for the Invention of "IMPROVEMENTS IN
MACHINES FOR MANUFACTURING CHAINS, CORDS, ROPES, AND THE MANNER OF
MAKING SUCH CHAINS CORDS AND RODES"
Sealed the 28th February 1868, and dated the 3rd September 1867.
PROVISIONAL SPECIFICATION left by the said Achille Edward Gelbaye
at the Office of the Commissioners of Patents, with his Petition, on the
3rd September 1867.
I, ACHILLE EDWARD GELHAYE, of Windmill Road, Croydon, in the County
of Surrey, Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINES FOR MANUFACTURING CHAINS, CORDS, ROPES, AND
THE MANNER OF MAKING SUCH CHAINS, CORDS, AND ROPES," to be as follows:-
. This Invention consists of a machine for and mode of weaving or reaving
a new kind of chain, cord, or rope which is constructed of metal wire, or of
vegetable or animal substances.
In carrying this Invention into effect I mount a cylinder upon a revolving
disc or table worked by steam or hand power, and round this cylinder I cut
or form two or more eccentric grooves or slots. Within the said cylinder' in
gear with a pinion I place any desired number of slides, and each of these
slides is provided with a projection or pin which works in the eccentric grooves
of the cylinder, and as the said cylinder revolves the whole of these slides are

page_text: caused to rise and fall. To each of the slides a hooked needle and clutch are
attached, so that when raised the hook of the needle catches the wire or
other substance, which is held by any number of revolving wheels placed as
found convenient on the disc, and as the eccentric grooves or slots by the
revolution of the cylinder cause the slides and needles to descend the clutch
closes on the wire and prevents its escaping till it has formed a loop, and when
the needle is again raised the clutch falls and allows the needle to hook the
wire again, and the operation is continued at each revolution. The chain thus
formed passes through a tube in the centre of the cylinder, and is wound up,
carded, or otherwise disposed of; the size and shape of this tube varies
according to the size and shape of the chain, and may be flat, round, or of
any other form. The eccentric grooves or slots can also be formed according
to the size of the chain required.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Achille Edward Gelhaye in the Great Seal Patent Office on
the 3rd March 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ACHILLE
EDWARD GELHAYE, of Windmill Road, Croydon, in the County of Surrey,
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of September, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Achille Edward Gelhaye, Her special licence that I, the said Achille Edward
Gelbaye, my executors, administrators, and assigns, or such others as I, the
said Achille Edward Gelhaye, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United, Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention; for "IMPROVE-
MENTS IN MACHINES FOR MANUFACTURING CHAINS, CORDS, ROPES, AND THE MANNER
OF MAKING SUCH CHAINS, CORDS, AND ROPES," upon the condition (amongst others)
that I, the said Achille Edward Gelhaye, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same to be

page_text: filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Achille Edward Gelhaye, do hereby
declare the nature of my said 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 consists of a machine for and mode of weaving or reaving a
new kind of chain, cord, or rope which is constructed of metal wire, or of
vegetable or animal substances.
In carrying this Invention into effect I mount a cylinder upon a revolving
disc or table worked by steam or hand power, and round this cylinder I cut
or form two or more eccentric grooves or slots, or the cylinder may be made
in two or more pieces, and be fastened together by bands, leaving one or more
eccentric openings all round between the several parts. Within the said
cylinder I place a grooved or serrated pillar or pinion, and within the grooves of
such pillar or pinion I place any desired number of slides, each of these slides
being provided with a projecting head or pin which works in the eccentric
groove of the cylinder, and thereby causes the slides themselves to rise or
fall as the cylinder revolves. To each of these slides a hooked needle and
clutch are attached so that when raised the hook of the needle catches the
wire or other substance which is held by any number of revolving reels placed
as found convenient on the disc or revolving cylinder, and as the eccentric
grooves or slots by the revolution of the disc and cylinder cause the slides
and needles to descend the clutch closes on the wire and prevents its escaping
till by the revolution of the cylinder it has formed a loop, when the needle is
again raised, and the clutch falls and allows the needle to hook the wire or
cord again, and the operation is renewed. The chain thus formed passes
through a tube in the centre of the grooved pillar or pinion inside the cylinder,
and is wound up, carded, or otherwise disposed of. The size and shape of
this tube varies according to the size and shape of the chain, and may be flat,
round, or of any other form, the eccentric grooves or slots can also be formed
according to the size of the chain required. Any desired number of guides
may also be bolted to the cylinder or disc for guiding the metal wire or thread
in the proper direction, and a cord or wire may also be passed down through
the hollow centre pinion, and thus form a centre to the chain. The size
of the inside grooved pillar or pinion, cylinder, disc, or other part of the
machine may also be varied in form and size as found necessary in practice.
But what I more particularly claim as my Invention is, the construction of
a machine as herein described, or a modification thereof, with the eccentric

page_text: grooved cylinder, hollow centre pinion, or grooved pillar with rising and falling
slides, needles, and clutches, the whole being worked by steam or hand power,
or by treadle, as preferred.
In witness whereof, I, the said Achille Edward Gelhaye, have hereunto
set my hand and seal, this Third day of March, in the year of our
Lord One thousand eight hundred and sixty-eight.
ACHILLE EDW. GELHAYE. (L.S.)
