IMPROVEMENTS IN MEANS OR APPARATUS FOR THE PRODUCTION OF NARROW WEAVINGS
Year: 1867

page_text: LETTERS PATENT to Thomas Tivey, of Derby, Manager, in the Employ of
Messrs. Joseph Davenport & Son, also of Derby, for the Invention of
"IMPROVEMENTS IN MEANS OR APPARATUS FOR THE PRODUCTION OF NARROW
WEAVINGS."
Sealed the 15th October 1867, and dated the 24th April 1867.
PROVISIONAL SPECIFICATION left by the said Thomas Tivey at the Office
of the Commissioners of Patents, with his Petition, on the 24th April
1867.
I, THOMAS TIVEY, of Derby, Manager, in the Employ of Messrs. Joseph
Davenport & Son, also of Derby, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MEANS OR APPARATUS FOR THE PRODUCTION OF
NARROW WEAVINGS," to be as follows:-
The object of the improvements is to effect economy of space in the
production of narrow weavings. For this purpose the shuttles in place of
traversing to and fro across the respective breadths in or upon stationary
supports each shuttle is supported by and passes from one to. the other of two
moveable supports; one of these supports for each shuttle is carried by one
bar, the other of these supports to each shuttle is carried by another bar.
These supporting bars are capable of movement in opposite directions, and they
are actuated by pins therefrom passing into inclined slots of a sliding plate or
otherwise to draw the supports for each shuttle towards each other at the time

page_text: of the shuttles being passed through the respective "sheds," and they then
move in the opposite direction to give a clear space for change of shed; the
shuttles are actuated by pinions, studs, or otherwise. By these means the
length of each shuttle in relation to the width of the fabric may be considerably
reduced.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Tivey in the Great Seal Patent Office on the
24th October 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
TIVEY, of Derby, Manager, in the Employ of Messrs. Joseph Davenport & Son,
also of Derby, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of April, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Thomas Tivey, Her special licence that I, the said Thomas Tivey, my
executors, administrators, and assigns, or such others as I, the said Thomas
Tivey, 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 MEANS
OR APPARATUS FOR THE PRODUCTION OF NARROW WEAVINGS," upon the condition
(amongst others) that I, the said Thomas Tivey, my executors or adminis-
trators, 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 Thomas Tivey, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof, that is to say :-
The object of the improvements is to effect economy of space n the
production of narrow weavings. For this purpose the shuttles in place of
traversing to and fro across the respective breadths in or upon stationary

page_text: supports each shuttle is supported
and passes from one to the other of two
moveable supports; one of these supports for each shuttle is carried by one
bar, the other of these supports to each shuttle is carried by another bar.
These supporting bars are capable of movement in opposite directions, and they
are actuated by pins therefrom passing into inclined slots of a sliding plate or
otherwise to draw the supports for each shuttle towards each other at the time
of the shuttles being passed through the respective "sheds," and they then
move in the opposite direction to give a clear space for change of shed; the
shuttles are actuated by pinions, studs, or otherwise. By these means the
length of each shuttle in relation to the width of the fabric may be considerably
reduced, and facility is given for forming the batten of iron.
But that the Invention may be fully understood I will, by the aid of the
accompanying Drawing, proceed to describe means pursued by me in carrying
the same into effect.
DESCRIPTION OF THE DRAWING.
Figure 1 shows a front view, Figure 2 an end view, and Figure 3 a plan
view of part of the batten and other of the parts of a loom arranged to carry
out my improvements; Figures 4, 5, 6, and 7 show parts separately full size.
In each of the views the same letters are employed to indicate corresponding
parts wherever they occur.
a shows part of the batten; b, reeds thereof; c is a portion of one end
framing of the loom, and d a bracket fixed thereto for operating the bars e
and carrying the moveable supports e¹ and f¹ for the shuttles g, g. It will
be seen, particularly by reference to the sectional and side views of one of the
shuttles at Figures 4 and 5 that each of the shuttles g is provided with a bar
or plate g of form adapted to admit of its sliding upon whilst being carried
by supports e or f¹; Figures 6 and 7 show an end view and a side view of one
of these supports e¹ or fl separately. The supports e' are, as stated, affixed to
the bar e, which is provided at one end with a projection & having at its lower
end a truck or bowl which moves in the slotted opening a formed in the
plate d, as the batten moves to and fro in the loom. f³ is another slotted
opening formed in the bracket d to receive the truck of a similar projection
from the bar f. By these means, when the batten is in the back and the sheds
in the breadths of fabric are open for the passage of the shuttles through the
respective sheds, the bars e and f will be moved so that a support e¹ and a
support f¹ will be moved one towards the other in each shed, thereby to aid
more fully in supporting the shuttles in passing through such sheds, and then
when the batten comes forward for the beat up the bars e and f will be

page_text: drawn in the opposite direction so that the end of each support and f¹ will
be clear of the warps of the fabrics.
Having thus described my improvements, and means: which I adopt in
carrying the same into effect, I would have it understood that I do not
confine. myself to, the precise details shown and described, as, the same may be
varied without departing from the peculiar character of the. Invention; but
what I claim. is, the forming the supports to the shuttles in pairs. moveable
in opposite directions in manner, and for the purpose substantially as
explained..
In witness whereof, I, the said Thomas. Tivey, have. hereunto set. my
hand and seal, this Twenty-first day of October; in. the year of our
Lord One thousand eight hundred and sixty-seven..
