IMPROVEMENTS IN WEAVING
Year: 1858

page_text: LETTERS PATENT to Frederick Edwards, of Hillfields, in the City of
Coventry, Machinist, and William Edwards, of Howard Street, in the
said City of Coventry, Machinist, for the Invention of "IMPROVEMENTS IN
WEAVING."
PROVISIONAL SPECIFICATION left by the said Frederick Edwards and
William Edwards at the Office of the Commissioners of Patents, with
their Petition, on the 31st March 1858.
We, FREDERICK EDWARDS, of Hillfields, in the City of Coventry, Machinist,
and WILLIAM EDWARDS, of Howard Street, in the said City of Coventry,
Machinist, do hereby declare the nature of our Invention of "IMPROVEMENTS
IN WEAVING," to be as follows:-
In the weaving of ribbons and other like fabrics where two or more colors
of shute or weft are required, and a batten with more than one shuttle for
each breadth of ribbon, usually called a double or treble batten, is used, it has
hitherto been the practice to employ rising and falling battens or shuttle
boxes, or parts of battens containing the shuttles; but our Invention consists
in constructing battens in which two or more shuttles are employed in weaving
each breadth of ribbon in such manner as to avoid the necessity of the batten
or shuttle boxes, or parts of the batten containing the shuttles, rising or falling,
and so as to produce a solid color with each shuttle, that is, the same color on
both sides, and through the thickness of the ribbon or like fabric.

page_text: And our Invention further consists in constructing the battens and the
jacquard machine, and the cards used therewith, in such manner as to permit
two shuttles carrying separate colors through the same breadth of ribbon to
pass simultaneously at one rising of the machine, and so as to produce each
color solid as aforesaid.
The manner in which we propose to carry out our intended, substitution for
rising and falling battens or shuttle boxes, or parts of battens containing the
shuttles, is by constructing and arranging the shuttles for each breadth of
ribbon, so that they pass substantially in succession horizontally in the same
line or plane, or by any other suitable or equivalent means.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick Edwards and William. Edwards in the. Great Seal.
Patent Office, on the 30th September 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FREDERICK
EDWARDS, of Hillfields, in the City of Coventry, Machinist, and WILLIAM
EDWARDS, of Howard. Street, in the said City of Coventry, Machinist, send.
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of March, in the year of our Lord.
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Frederick Edwards and William Edwards, Her special licence that we,
the said Frederick Edwards and William Edwards, our executors, adminis-
trators, and assigns, or such others as we, the said Frederick Edwards and:
William Edwards, our 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-
WEAVING," upon the condition (amongst others) that we, the said Frederick
Edwards and William Edwards, or one of us, our executors or administrators,
by an instrument in writing under our, or their, or one of our or 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.

page_text: NOW KNOW YE, that we, the said Frederick Edwards and William
Edwards, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, reference being had to the
Drawings hereunto annexed, that is to say :-
The object of this Invention is to prevent the necessity of using rising and
falling shuttle boxes, and to substitute a fixed shuttle race or fixed shuttle
races on the top of the case or box containing the slides and other working
parts connected to an ordinary narrow fabric weaving loom; also to pass the
shuttles through the same shed as in an ordinary single batten loom. The
shuttles employed in carrying out our Invention are of improved forms, each
one carrying a quill supported in an opening as in ordinary shuttles.
In the accompanying Drawings we have shewn one of our improved
shuttles, of which Figure 1 is a top view, and Figure 2a front view. A is
the body of the shuttle having grooves a cut in on the front and back, the
upper part of the shuttle is in most cases bowed outward, and when thus bowed
is so formed that the bowed parts may pass over the top of the body of the
shuttle placed in front it. Near the ends of the shuttles, boles a¹, a', are formed,
into which holes pins are inserted for the purpose of shifting or sliding the
shuttles from one race to the other. Figure 3 shews in front view the manner
in which the shuttle boxes or races are applied to the top of the case or box
containing the slides and rollers of an ordinary narrow fabric weaving loom.
Figure 4, is a top view or plan with the pillars or uprights, carrying the sley
beam, shewn in section. In this view we have shewn three double shuttle
races b, 6, 6, which are fixed to the top of the case. Motion is communi-
cated to the shuttles in the following manner-Underneath the case slide
bars B, B', B", are caused to move to and fro by means of cords or straps
fixed thereto, and passings over pulleys c, c', which pulleys likewise act as
rollers for the bars to run on. The other ends of the cords are connected to
treadles in the ordinary manner. On each of the bars B, B', B, lugs or
projections d, d', are fixed, one of which takes into a hook e formed on the end
of the flat bar e¹. The upper part of this bar is secured to a slide C ; portions
are cut away from the bottom of this slide as shewn, to enable it to fall on to
another pair of rollers e", e", when it has travelled sufficiently far to allow it
to.do so. On the top of the slide C a pin f is fixed, this pin f is just long
enough to catch the shuttle by the hole a¹ which it enters, and then draws
the shuttle from left to right, or from right to left according to the way the
loom is working. To each shuttle there must be two slides similar to C, one
placed behind the other, and provided with hooked bars and pins, the two
:

page_text: slides work together part of the distance only, that is to say, the pin on one
slide carries the shuttle a certain distance when the cut away part of that slide
drops down upon the rollers e", ell, and the pin f ceases to hold the shuttle.
At the same time the pin on the other slide comes into operation, and catches
the other end of the shuttle and draws it the remainder of the distance it has
to travel, when the slide is stopped by abutting against a fixed stop f¹ placed
near the centre of the frame. All the shuttles employed are so timed as to
work when required for the throwing in of the various colours for the produc-
tion of any desired design. Figure 5 shews the positions of four slides C
during the first motion of the front pair.
And having now described the nature of the said Invention, and in what.
manner the same is to be performed, we declare that we do not confine our-
selves to the foregoing details, as the same may be varied without departing
from the essential features of our Invention; but what we claim is,―
First, the improved construction of shuttles herein-before described, and
illustrated in the Drawings hereunto annexed.
Secondly, the employment in the manufacture of ribbons and other fabrics,"
of fixed shuttle races and shuttles moving at the same level, or in the same
plane, in the manner and for the purposes herein-before described, and illus
trated in the Drawings hereunto annexed.
In witness whereof, we, the said Frederick Edwards and William
Edwards have hereunto set our hands and seals, this Twenty-eighth
day of September, One thousand eight hundred and fifty-eight.
