Year: 1883

page_text: LETTERS PATENT to George Edward Vaughan, of 57 Chancery Lane, in the
County of Middlesex, Patent Agent, for an Invention of "IMPROVEMENTS IN
THE MANUFACTURE OF ROPES," communicated to him from abroad by Samuel
Trott, and Frederick Adam Hamilton, both of the City of Halifax, in the
province of Nowe Sectio in the Dominion of Canada
.
PROVISIONAL SPECIFICATION left by the said George Edward Vaughan
at the Office of the Commissioners of Patents on the 14th November 1883.
GEORGE EDWARD VAUGHAN, of 57 Chancery Lane, in the County of Middlesex,
Patent Agent,
"IMPROVEMENTS IN THE MANUFACTURE OF ROPES, A communi-
cation to me from abroad by Samuel Trott, and Frederick Adam Hamilton, both of
the City of Halifax, in the province of Nova Scotia, in the Dominion of Canada,
This invention relates to improvements in the manufacture of ropes from hemp
or other suitable fibre, specially suitable to be employed in considerable lengths for
dredging or grapling and for various marine and other analogous purposes. The
object of the said improvements is to prevent the untwisting or unlaying of the
yarns or strands, constituting the rope, and, the consequent formation of kinks.
The hemp or other suitable fibre is made up into yarns of "right hand" and
"left hand "twist "or lay" and the rope is manufactured of two or more layers or
servings of the said yarns, such layers or servings being composed alternately of
yarns of left hand twist or lay so arranged as to form right hand layers or servings
and yarns of right hand twist or lay arranged to form left hand layers or servings.
There is no necessity that the number of right hand layers or servings should
correspond with the number of left hand layers or servings, but, in all cases, there
must at least be one right hand layer or serving of yarn of left hand twist or lay
and one left hand layer or serving of yarn of right hand twist or lay. Instead of
forming the layers or servings of yarn as lastly described, the yarn is, in some
cases, made into strands in which case left hand strands composed of right hand
yarns are laid on in right band servings and are substituted for left hand yarns,

servings and are substituted for right hand yarns. It will be readily understood
that in the same rope there may be layers or servings of yarn and also layers or
servings of strands.
The strands constituting the layers or servings may be formed with a wire or 5
wires in the centre thereof, and the rope may have, when desired, any suitable core
around which the first layer or serving is laid.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said George Edward Vaughan in the Patent Office on the 14th May
1884.
GEORGE EDWARD VAUGHAN of 57 Chancery Lane, in the County of Middlesex,
Patent Agent,
"IMPROVEMENTS IN THE MANUFACTURE OF ROPES," a communi-
cation to me from abroad by Samuel Trott and Frederick Adam Hamilton, both of
the City of Halifax, in the Province of Nova Scotia, in the Dominion of Canada,
This invention relates to improvements in the manufacture of ropes from hemp
or other suitable fibre, specially suitable to be employed in considerable lengths for
dredging or grapling and for various marine and other analogous purposes. The
object of the said improvements is to prevent the untwisting or unlaying of the
yarns or strands constituting the rope and the consequent formation of kinks.
The hemp or other suitable fibre is made up into yarns of "right hand" and
"left hand' "twist" or "lay" and the rope is manufactured of two or more layers
or servings of the said yarns, such layers or servings being composed alternately of
yarns of left hand twist or lay so arranged as to form right hand layers or servings
and yarns of right hand twist or lay arranged to form left hand layers or servings.
There is no necessity that the number of right hand layers or servings should
correspond with the number of left hand layers or servings, but, in all cases, there
must at least be one right hand layer or serving of yarn of left hand twist or lay
and one left hand layer or serving of yarn of right hand twist or lay. Instead of
forming the layers or servings of yarn as lastly described, the yarn is, in some
cases, made into strands in which case left hand strands composed of right hand
yarns are laid on in right hand servings and are substituted for left hand yarns,
whilst right hand strands composed of left hand yarns are laid on in left hand
servings and are substituted for right hand yarns. It will be readily understood
that in the same rope there may be layers or servings of yarn. and also layers or
servings of strands.
The strands constituting the layers or servings may be formed with a wire or
wires in the centre thereof, and the rope may have, when desired, any suitable core
around which the first layer or serving is laid.
Having thus described and ascertained the nature of the said Invention and the
manner in which the same is to be performed, I would observe in conclusion that
what I consider novel and original and therefore claim as constituting the invention
secured to me by the said hereinbefore in part recited Letters Patent, is:-
First. In the manufacture of ropes the combination of yarns of right hand and
left hand twist or lay arranged respectively in left hand and right hand layers or
servings, substantially as hereinbefore described and set forth.

page_text: Secondly. In the manufacture of ropes the combination of left hand strands,
composed of right hand yarns, laid on in right hand servings, and of right hand
strands composed of left hand yarns, laid on in left hand servings, substantially as
herein before set forth and described.
And thirdly. In the manufacture of ropes the combination of right hand and left
hand strands and yarns, substantially as hereinbefore set forth and described.
In Witness whereof I the said George Edward Vaughan have hereunto set my
band and seal this fourteenth day of May in the year of our Lord One thousand
eight hundred and eighty four.
