PROVISIONAL SPECIFICATION left by the said James Holmes and
Joshua Holmes at the Office of the Commissioners of Patents,
with their Petition, on the 14th March 1873.
We, JAMES HOLMES and JOSHUA HOLMES, Weaving Overlookers, of
Bradford, in the County of York, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN SHUTTLES FOR WEAVING," to be as
follows, that is to say:
Our Invention relates to a mechanical arrangement whereby the peg
of the shuttle is brought with more certainty than at present to the
centre of the shuttle when the bobbin is placed on the peg and enters
the bobbin space, also causing the pressure acting on the peg to press in
a direct line with the tips, thereby preventing the splitting of the
shuttle.

page_text: To carry out our Invention we employ a spring fixed in the shuttle
between the shoulder and tip, in which is placed a stud. The head of
this stud presses against the head and lock of the peg, keeping it firmly
in its position. In the head of the peg near the bottom is fitted a pin
which passes through the shuttle sides, forming a centre pin on which
the peg moves. On the top of the head of the peg and at the extremity
is formed the lock. A pin is also fitted in the shuttle sides at the top,
passing over the head of the peg and acting on the top side of the head
and on the lock; this pin prevents the peg from falling below the
centre of the shuttle. When a bobbin is required to be placed on the
peg the peg is moved out of the bobbin space; the lifting of the peg
causes it to move on the centre pin, giving the lock a slanting position,
thereby pressing in the spring and consequently the head of the stud.
Directly the bobbin is placed on the peg and pressed in the bobbin space
the spring forces the lock to act, which coming in contact with the top
pin prevents the peg and bobbin moving up or down, and allows them
to keep a central position in the shuttle. The spring being fitted in the
shuttle between the shoulder and tip (the strongest part of the shuttle),
causes the pressure acting on the peg to press in a direct centre line with
the tips, preventing the splitting of the shuttle, which often takes place
with the present methods of fixing pegs in shuttles.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Holmes and Joshua Holmes in the Great
Seal Patent Office on the 12th September 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
HOLMES and JOSHUA HOLMES, Weaving Overlookers, of Bradford, in the
County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of March, in the
year of our Lord One thousand eight hundred and seventy-three, in the a
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said James Holmes and Joshua Holmes,
Her special licence that we, the said James Holmes and Joshua Holmes,
our executors, administrators, and assigns, or such others as we, the said
James Holmes and Joshua Holmes, our executors, administrators, and

page_text: 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 "IMPROVEMENTS IN SHUTTLES FOR WEAVING," upon
the condition (amongst others) that we, the said James Holmes and
Joshua Holmes, our executors or administrators, by an instrument in
writing under our, 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 we, the said James Holmes and Joshua
Holmes, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, reference being had
to the Drawing hereto annexed, and to the figures and letters marked
thereon, that is to say :-
Our Invention relates to a mechanical arrangement whereby the peg
of the shuttle is brought with certainty to the centre of the shuttle when
the bobbin is placed on the peg and enters the bobbin space, also causing
the pressure acting on the peg to press in a direct line with the tips,
thereby preventing the splitting of the shuttle.
.
To carry out our Invention we employ a spring fixed in the shuttle
between the shoulder and tip, in which is placed a stud. The head of
this stud presses against the head and lock of the peg, keeping it firmly
in its position. In the head of the peg near the bottom is fitted a pin
which passes through the shuttle sides, forming a centre pin on which
the peg moves. On the top of the head of the peg and at the extremity
thereof is formed the lock. A pin is also fitted in the shuttle sides at
the top, passing over the head of the peg and acting on the top side of
the head and on the lock. This pin prevents the peg from falling below
the centre of the shuttle. When a bobbin is required to be placed on
the peg, the peg is moved out of the bobbin space; the lifting of the
peg causes it to move on the centre pin, giving the lock a slanting
position, thereby pressing in the spring and consequently the head of
the stud. Directly the bobbin is placed on the peg and pressed in the

page_text: bobbin space the spring forces the lock to act, which coming in contact
with the top pin prevents the peg and bobbin moving up or down, and
allows them to keep a central position in the shuttle. The spring being
fitted in the shuttle between the shoulder and tip (the strongest part of
the shuttle) causes the pressure acting on the peg to press in a direct
centre line with the tips, preventing the splitting of the shuttle, which
often takes place with the present methods of fixing pegs in shuttles.
But in order to enable our improvements to be better understood we
will proceed to describe the same by reference to the accompanying
Drawing, in which Figure I represent a sectional side elevation of the
Similar letters of reference

are used to represent similar parts.
A is a spring fixed between the shoulder B and tip C of the shuttle.
In this spring is placed a stud D, shewn in dotted lines. The head E
of the stud D presses against the head F and lock I of the peg G, 1
keeping it firmly in its position. The spring A being fitted in the
shuttle between the shoulder B and tip C causes the pressure acting on
the peg G to press in a direct line with the tip C, thus preventing the
splitting of the shuttle which heretofore often took place. In the
head F of the peg G near the bottom is fitted a pin H passing through
the shuttle sides, forming the centre pin on which the peg G moves.
On the top of the head F of the peg G is formed the lock I. A pin J is
also fitted in the shuttle sides, passing over the head F and acting on
the top side and against the lock I, preventing the peg G falling below
the centre of the shuttle. When a bobbin is required to be placed on
the peg G this peg is moved out of the bobbin space K, as shewn by
the dotted lines. The lifting of the peg causes it to move on the centre
pin H, giving the lock I a slanting position, thereby pressing in the
spring A, and consequently the head E of the stud D. Directly the
bobbin is placed on the peg G and pressed in the bobbin space K the
spring A forces the lock I to act, and coming in contact with the top
pin J it prevents the peg and bobbin from moving up or down,
allowing it to keep a central position in the shuttle.
Having thus described our improvements, and the best means we are
acquainted with for carrying the same into effect, we would have it
understood that we do not confine ourselves to the precise details shewn
and described, as the same may be varied without departing from the

page_text: peculiar character of the Invention, but what we do claim is, the
arrangement whereby the peg of the shuttle, when the bobbin is placed
on the peg and enters the bobbin space, is brought to the centre of the
shuttle, and the pressure of the spring acting on the peg causes it to
press in a direct line with the tips, thereby preventing the splitting of
the shuttle, substantially as herein-before described and represented by
the accompanying Drawing.
In witness whereof, we, the said James Holmes and Joshua Holmes,
have hereunto set our hands and seals, this Eleventh day of
September, One thousand eight hundred and seventy-three.
