IMPROVEMENTS IN THE CONSTRUCTION OF SHUTTLES
Year: 1872

page_text: LETTERS PATENT to William Henry Platt, of Ashton-under-Lyne, in
the County of Lancaster, Shuttle Maker, for the Invention of
“IMPROVEMENTS IN THE CONSTRUCTION OF SHUTTLES.”
Sealed the 4th March 1873, and dated the 10th December 1872.
PROVISIONAL SECIFICATION left by the said William Henry Platt
at the Office of the Commissioners of Patents, with his Petition,
on the 10th December 1872.
I, WILLIAM HENRY PLATT, of Ashton-under-Lyne, in the County of
Lancaster, Shuttle Maker, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF SHUTTLES," to be as
follows:-
My Invention consists in an improved mode of constructing the
shuttle peg, and the spring by which the cop is held on the shuttle peg.
Instead of making the shuttle peg solid as now customary I make it
of sheet steel or iron pressed into the form of a hollow frame, which
forms a guide for a continuous double spring. The shuttle peg is

page_text: jointed to the body of the shuttle by a pin as usual, and a second pin
passes through the shuttle, which second pin is placed in such a position
that when the shuttle peg is raised to put on a cop the upper side of
the double spring comes in contact with it, and by this means the spring
is pressed close to the shuttle peg to allow the cop to be put on with !
facility.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said William Henry Platt in the Great Seal Patent
Office on the 9th June 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY PLATT, of Ashton-under-Lynė, in the County of Lancaster,
Shuttle Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of December, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Henry Platt, Her special
licence that I, the said William Henry Platt, my executors, adminis-
rators, and assigns, or such others as I, the said William Henry
Platt, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might
make, usc, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man', an Invention
for "IMPROVEMENTS IN THE CONSTRUCTION OF SHUTTLES," upon the con-
dition (amongst others) that I, the said William Henry Platt, 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 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 William Henry Platt, do hereby
declare the nature of my said "Invention, and in what manner the same

page_text: is to be performed, to be particularly described and ascertained in and by
the following statement (that is to say) :-
My Invention consists in an improved mode of constructing the
shuttle peg and the spring by which the cop is held on the shuttle peg.
Instead of making the shuttle peg solid as now customary I make it
of sheet steel or iron pressed into the form of a hollow frame, which
forms a guide for a continuous double spring. The shuttle peg is jointed
to the body of the shuttle by a pin as usual, and a second pin passes
through the shuttle, which second pin is placed in such a position that
when the shuttle peg is raised to put on a cop the upper side of the
double spring comes in contact with it, and by this means the spring is
pressed close to the shuttle peg to allow the cop to be put on with facility.
And in order that my Invention may be fully understood and readily
carried into operation, I will proceed to describe the accompanying
Sheet of Drawings, reference being had to the figures and letters marked
thereon.
Fig. 1 is a longitudinal section of a shuttle to which my improve-
ments are applied; Fig. 2 is a plan; and Fig. 3, a transverse section of
the same; in these views a is the shuttle peg, which instead of being
solid as usual I now make of sheet steel or iron, which is pressed into
the form of a hollow frame, as shewn best in section in Fig. 3, which
hollow frame forms a guide for the continuous double spring b, c; the
shuttle peg is hinged as usual to the fulcrum pin d, and a second pin e
is placed above and a little to the left of the fulcrum pin d, as shewn in
Fig. 1. The outer end of the spring 6 is soldered as usual to the end of
the shuttle peg, and the other end after passing above the fulcrum pin d
and under the guide pin e is turned down and carried through a slot in
the ordinary spring' which acts on the heel of the shuttle peg. The
outer end of the small spring c is also soldered to the end of the shuttle
peg, and the other end bears on the inside of the shuttle peg.
When the shuttle peg is raised, as shewn by the dotted lines in Fig. 1,
the lower end of the spring b comes against the guide pin e and the
turned down end of the spring is held by the end of the slot in the
spring; by this means the spring is pressed down and drawn tight or
nearly in line with the upper edge of the hollow frame, forming the
shuttle peg to allow the cop to be put on with facility, but when the

page_text: shuttle peg is pressed down into the shuttle, the double spring is at
liberty to rise and to bind the cop securely to the shuttle peg, thereby
preventing the cop from being knocked off and holding the end until all
the yarn is unwound.
Having thus stated the nature of my Invention and described the 5
manner of performing the same, I declare that I claim making the
shuttle peg in the form of a hollow frame, as shewn and described.
In witness whereof, I, the said William Henry Platt, have hercto
set my hand and seal, this Sixth day of June, One thousand
eight hundred and seventy-three.
