IMPROVEMENTS IN SHUTTLES FOR WEAVING NARROW FABRICS, AND IN MOUNTING AND FITTING THEM TO THE BATTENS
Year: 1863

page_text: LETTERS PATENT to Josiah Gimson, of the Town and County of
Leicester, Engineer, for the Invention of "IMPROVEMENTS IN SHUTTLES
FOR WEAVING NARROW FABRICS, AND IN MOUNTING AND FITTING THEM TO THE
BATTENS."
Sealed the 29th December 1863, and dated the 4th July 1868.
PROVISIONAL SPECIFICATION left by the said Josiah Gimson at the
Office of the Commissioners of Patents, with his Petition, on the 4th
July 1868. .
I, JOSIAH GIMSON, of the Town and County of Leicester, Engineer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN SHUTTLES
FOR WEAVING NARROW FABRICS, AND IN MOUNTING AND FITTING THEM TO THE
BATTENS," to be as follows:-
In mounting and fitting shuttles in the battens of narrow fabric looms it
has been usual hitherto to mount them between upper and lower race planks
having angular or square-edged bearing surfaces approaching somewhat
closely together, fitting into grooves in the sides of the shuttles, and with the
spool or bobbin disposed in the shuttle either in front or at back of the race
planks.
Now, my Invention consists in disposing the bobbin somewhat centrally,
that is, neither in front of, nor behind the race planks, but between them, the
bearing surfaces of the race planks being so formed and adapted as to afford
room for disposing the bobbin as described, and at same time affording the
necessary support and guidance for the shuttle. For this purpose I dispose
the upper and lower race planks much wider apart than usual, in fact, equal to

page_text: the greatest thickness of the shuttle, which being somewhat greater than the
largest diameter of the bobbin, provides plenty of room for it in the position
desired. A plate is fixed on the back of the shuttle of greater breadth than
the thickness or depth of the shuttle, which plate is enclosed by a, covering
piece fixed to the batten, guiding and keeping the shuttle in position in the
race; other methods may, of course, be adopted for keeping the shuttle in
position in the race, and the central position of the bobbin still retained. By
adopting this position the shuttle is balanced in its bearings, and the bobbin
being at the widest part of the shed, large bobbins may be used, which in
this position may also be longer than ordinary bobbins, and therefore containing
a much larger quantity of material and necessitating a less frequent change of
bobbin than ordinary.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Josiah Gimson in the Great Seal Patent Office on the
2nd January 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, J, JOSIAH
GIMSON, of the Town and County of Leicester, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of July, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Josiah Gimson, Her special licence that I, the said Josiah
Gimson, my executors, administrators, and assigns, or such others as.I, the
said Josiah Ginson, 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.
"IMPROVEMENTS IN SHUTTLES FOR WEAVING NARROW FABRICS, AND IN MOUNTING
AND FITTING THEM TO THE BATTENS," upon the condition (amongst others) that
I, the said Josiah Gimson, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should par-
ticularly 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.

page_text: NOW KNOW YE, that I, the said Josiah Gimson, 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, reference being had to the Sheet of Drawings hereunto annexed,'
and to the letters and figures marked thereon (that is to say) :-
In mounting and fitting shuttles in the battens of looms for weaving narrow
fabrics it has been usual hitherto to mount them between upper and lower:
race planks having angular or square-edged bearing surfaces approaching:
somewhat closely together, and fitting into grooves in the sides of the shuttles,
in which shuttles the spools or bobbins have been disposed either in front or
at back of the race planks.
Now, my Invention consists in disposing the bobbin somewhat centrally,
that is, neither in front of nor behind the race planks of the batten, but
between them, the bearing surfaces of the race plank being so formed,
arranged, and adapted as to give room for disposing the bobbin as described,
and at same time affording the necessary support and guidance for the
shuttle. For this purpose I dispose the upper and lower race planks of the
batten much wider apart than usual, in fact, equal to the greatest thickness of:
the shuttle, which being somewhat greater than the largest diameter of the
bobbin, provides plenty of room for it in the position desired. A plate is fixed
on the front of the shuttle of greater breadth than the thickness and depth of
the shuttle, which plate is enclosed by a covering piece fixed to the batten,'
guiding and keeping the shuttle in position in the race; other methods may,.
of course, be adopted of keeping the shuttles in position in the race, while
the central position of the bobbin is still retained. By adopting this position!
the shuttle is better balanced in its bearings, and the bobbin being disposed. at
that part of the shed which is opened - widest, large bobbins may be used..
Moreover, in this position the bobbins, being larger than those usually
employed, will contain a much larger quantity of material, and necessitates a
less frequent change of bobbin than in ordinary.

page_text: of the shuttle is a plate e, which.forms a wearing surface, and runs on the
lower race plank, while the shuttle is held in position by a plate f, which I
prefer to be of metal, but which may be of any other suitable material. This
plate is covered in by a piece g, fixed on the race planks, and runs in a
groove or channel cut therein; the piece 9 keeps the shuttle in position, and
being of the same length as the race planks the shuttle is perfectly guided at
all times; the shuttle, moreover, being better balanced in the race than here-
tofore, the principal weight being at the bobbin, is more easily guided and
moves with greater freedom than if unbalanced, or imperfectly so, as heretofore.
The plate f, being of metal, may be made to balance the shuttle perfectly on
the bottom race plank, and with a view to render the balancing more easily
effected, the bottom race plank is made somewhat thicker than the upper
one, as seen. The fittings of the bobbin and appliances for regulating the
tension of the thread will not need individual mention, being much the same
as usual, and do not require particular description..
Fig. 4 represents a cross section of a shuttle in the race planks with the
bobbin disposed as before described, but in which the guiding faces of the
race planks are somewhat differently formed, therefore showing some little
modification of the foregoing arrangement; in other respects it is the same, and
need not be further described.
Having described the nature of my Invention, and the manner of performing
the same, I declare that what I claim as my Invention to be protected by the
herein-before in part recited Letters Patent is,-
First, the use and application of the shuttles herein-before described and
represented in the Drawings annexed applied for weaving narrow fabrics.
Secondly, I claim fitting and mounting shuttles and bobbins in the race
planks of looms for weaving narrow fabrics in manner herein-before described.
In witness whereof, 1, the said Josiah Gimson, have hereunto set my
hand and seal, this Thirty-first day of December, in the year of our
Lord One thousand eight hundred and sixty-three.
JOSIAH GIMSON. (L.)
