Year: 1856

page_text: LETTERS PATENT to William Brierley and James Platts Brierley, of Cleck-
heaton, in the County of York, Machine Makers, for the Invention of
"IMPROVEMENTS IN LOOMS FOR WEAVING."
Sealed the 19th September 1856, and dated the 22nd March 1856.
PROVISIONAL SPECIFICATION left by the said William Brierley and
James Platts Brierley at the Office of the Commissioners of Patents,
with their Petition, on the 22nd March 1856.
We, WILLIAM BRIERLEY and JAMES PLATTS BRIERLEY, of Cleckheaton, in
the County of York, Machine Makers, do hereby declare the nature of the said
Invention for IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
Our Invention relates to the "rising boxes" used for changing the shuttles,
and consists in a method of working or lifting and falling them by the direct
action or beat-up of the lathe, and an arrangement of apparatus in connection
therewith, being self-acting and capable of adjustment, whereby a change of
shuttles to the number of six can be made at any desired "pick" or shoot of
weft. The accompanying outline drawings, and letters of reference will more
clearly explain the nature of our Invention, the same letters referring to the
same parts in each Figure. Fig. 1 is an end elevation of a loom *partly in
section; Fig. 2 is a plan of one end of the same, also partly in section.

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
BRIERLEY and JAMES PLATTS BRIERLEY, of Cleckheaton, in the County of York,
Machine Makers, send greeting.
WHEREAS, Her most Excellent Majesty Queen Victoria, by Her Royal
Letters Patent, bearing date the Twenty-second day of March, in the year of
our Lord One thousand eight hundred and fifty-six, in the nineteenth of
year
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said William Brierley and James Platts Brierley, Her special licence,
that we, the said William Brierley and James Platts Brierley, our executors,
administrators, and assigns, or such others as we, the said William Brierley
and James Platts Brierley, 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, exer-
cise and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN LOOMS
FOR WEAVING," upon the condition (amongst others) that we, the said William.
Brierley and James Platts Brierley, by an instrument in writing, under our
.hands and seals, or under the hand and seal of one of us, 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 Royal Letters Patent.
NOW KNOW YE, that I, the said William Brierley, for and on behalf of
myself and the said James Platts Brierly, do hereby declare the nature of the
said Invention, and in what manner the same.is.to be performed, to be par-
ticularly described and ascertained in and by the following statement (that is
.to say) :-
Our Invention relates to the rising boxes" used for changing the shuttles.
tand consists in a method of working or lifting and falling them by the direct

page_text: action or beat-up of the lathe, and an arrangement of apparatus in connection
therewith being. self-acting and capable of adjustment, whereby a change of
shuttles to the number of six can be made at any desired "pick" or shoot of
weft. The accompanying Sheet of Drawings, with the letters of reference
thereon, will more clearly explain the nature of our Invention, the same letters
referring to the same parts in each Figure.
Fig. 1 is an end elevation of a loom, partly in section; Fig. 2 is a plan
of one end, also partly in section; and Fig. 3 is a back elevation of the
same end. a is the crank shaft; b, the lathe; c, the rising boxes; d, a plate
spur wheel, carried on a stud and driven by a pinion fixed on the crank
shaft; e are portable tappets fixed on the side of the wheel for operating upon
the levers and g; h is a lever for actuating the beam i and hook j for
raising the boxes c; the incline slide piece is moved by the lever f into a
position for contact with h (when required) as the lathe beats up; the
lever g actuates the lever 1, bringing it into contact with and operating upon
the stop lever or holder m (when required) by means of the tumbler n,
which on being released is brought back by the spring o, and takes into a
notch c¹ in the boxes, thereby holding them up.
Figs. 5 and 6 are detail views of the tumbler n; and Fig. 7 is a part of the
lever and support ; and Fig. 8, the lever h; & Fig. 9, part of the hook j. It
will be seen, that when one of the tappets e on the wheel d acts upon the projec-
tion on the lever f (as the wheel rotates) the incline piece k will be moved into
the position represented by the dotted lines in Fig. 2; and on the lathe beating
up or moving forward, the lever h will come in contact therewith, and slide up
the said incline, the other end of the said lever h being connected to the beam i
by a rod; the hook j will raise the boxes to the required position, the holder m
sliding over, and being pressed by the spring o will take into the next notch
and hold the boxes up, whilst the hook j will, by the pressure of the spring p,
as the lathe moves backward take into the next notch ready to raise another
box at the required time. And if it be desired to raise the next box or boxes
in succession, then we arrange the tappets on the wheel according to the, time
or "pick" required; but if we desire to lower a box or boxes, the hook j is
removed from the notch by the lever q being drawn by the lever i into gear
with the bell-crank lever r, as seen in Fig. 8; the hook j will be raised to the
5 next notch without lifting the boxes. The lever is moved into the position
represented by the dotted lines in Fig. 2, where it will come in contact with
the tumbler n as the lathe beats up, forcing the said tumbler into the position
indicated by the dotted lines in Fig. 5. When the holder m is .withdrawn
from the notch, the boxes rest upon the hook, and as the lathe moves backward

page_text: it lowers the boxes to the proper place, and the holder m being released from
the tumbler is again forced into the notch by the spring o. By these, our
improved arrangements of apparatus, it will be apparent that, although in our
Provisional Specification we limited ourselves to six boxes, yet by suitable
arrangements of tappets and gear wheels the number of the boxes may be
extended without departing from the principle of the Invention. The boxes
may also be worked as shewn by the lever s, and tappets or antifriction studs t,
the other parts of these: our improvements operating as herein described.
Having; thus fully described and ascertained the nature and particulars of
this our Invention, and the manner of carrying the same into practical effect,
we would have it understood that we do not confine ourselves to the precise
details of arrangement as herein set forth; but we claim as our Invention the
method of working "rising boxes," as herein described, and illustrated in the
accompanying Sheet of Drawings, or any modification thereof:
In witness whereof, I, the said William Brierley, for and on behalf of
myself and the said James Platts Brierley: have hereunto set my hand
and seal, this Twentieth day of September, One thousand eight hundred
and fifty-six.
WILLIAM BRIERLEY. (L.S.)
Signed, sealed, and delivered by the within-
named William Brierley in the presence of
