Year: 1867

page_text: LETTERS PATENT to Adam Bullough, of Blackburn, in the County of
Lancaster, Cotton Manufacturer for the Invention of "IMPROVEMENTS IN
LOOMS FOR WEAVING."
Sealed the 9th June 1868, and dated the 13th December 1867.
PROVISIONAL SPECIFICATION left by the said Adam Bullough, at the
Office of the Commissioners of Patents, with his Petition, on the
13th December 1867.
I, ADAM BULLOUon, of Blackburn, in the County of Lancaster, Cotton
Manufacturer, do hereby declare the nature of the said Invention for "Im-
PROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
The object of this Invention is the weaving of two (or more) pieces of
narrow cloth in one loom, each piece being woven and having selvages perfect
and independent of each other.
In constructing looms according to this Invention I attach one end of a rod
or strap to one of the pickers which is continued in front of the slay to the
picker in the opposite box. Near the centre of the slay I fix two studs carry-
ing & spindle on which works a third picker also attached to the rod or
strap above mentioned. I thus divide the shuttle "race" into two lengths,
having a reed space for each and a third shuttle space between the two reed
spaces.
The action of the loom is as follows:-A shuttle being placed in the right-
band box and one in the centre shuttle space a pick from the right hand
impels the shuttle from that box across the race into the centre shuttle. space.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ADAM
BULLOUGH, of Blackburn, in the County of Lancaster, Cotton Manufacturer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of December, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
reign, did for Herself, Her heirs and successors, give and grant unto me, tho
said Adam Bullough, Her special licenco that I, the said Adam Bullough,
my executors, administrators, and assigns, or such others as I, the said
Adam Bullough, 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,
tho Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
Looms FOR WEAVING," upon the condition (amongst others) that 1, the said
Adam Bullough, my executors or administrators, by an instrument in writing
under my, or their, or one of their bands and seals, should particularly
describo 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 Adam Bullough, 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.
The object of this Invention is the weaving of two (or more) pieces of
narrow cloth in one loom, each piece being woven and having selvages perfect
and independent of each other.
In constructing looms according to this Invention I attach one end of a
rod or strap to one of the pickers, which rod is continued in front of the slay
to the picker in the opposite box. Near the centre of the slay I fix two studs

page_text: (or castings) carrying a spindle on which works a third picker also attached
to the rod or strap above mentioned. I thus divide the shuttle "race" into
two lengths, having a reed space for each and a third shuttle space between
the two reed spaces.
The action of the loom is as follows:-A shuttle being placed in the right-
hand box and one in the centre shuttle space a pick from the right hand impels
the shuttle from that box across the race into the centre shuttle space. The
shuttle from the latter space is impelled across the race of the second reed
space and enters the shuttle box at the left hand of the loom and vice versa.
Such being the nature and object of this my said Invention I will now
proceed to describe the same in detail, and in order that the same may be clearly
understood I bave hereunto annexed two Sheets of Drawings, and I have
marked the same with figures and letters of reference, the same letter referring
to the same part in the various views:-
Fig. 1 is a front elevation of such parts of a loom as relates to this Inven-
ton; Fig. 2 is an elevation of the back of the loom.
Fig. 3 (Sheet Two) is an enlarged view of the centre shuttle box; and Fig. 4
is an enlarged view of apparatus for purposes herein-after described.
At A, A, is shewn side frames and cross rails; B, a hollow rod attached to
the pickers 1, 2, 3, by means of cotters and pins. At C is shewn casting
carrying picker spindle D and forming the centre shuttle space or box E (a
spring & secured to the casting by the set screws is expanded by the shuttle
on its entrance to this box and prevents the shuttle rebounding). A shuttle
being placed in the right-hand box and one in the centre shuttle space E a pick
from the right hand (by means of the ordinary strap and apparatus) impels
the shuttlo from that box to the centre box E, and the shuttle from the centro
box enters the box at the left of the loom. F, F, are the reed spaces; G, G,
are the warp beams supported at one end by the stand H; J, J, the ordinary
levers and weights; K is the back bearer. A weft fork is applied at each side
of the loom and connected by a rod extending along the front of the slay;
these forks are in action and construction the ordinary weft forks. At M is
shewn apparatus for "letting back" the cloth and yarn when from any cause
desirable (sec cularged view); the cloth N is passed under and over the rods
n and through the eye P, thence over the brest beam R to the cloth roller S.
When it is desirable to "let back" the cloth the wheel T on the spindle of
which is the worm U working in the rack V being turned will raise the rack
to which the eye P is attached and let back the cloth. W is a casting bolted
to the cross rail A carrying the worm spindle and rack; the back of the latter
is grooved and receives a dovetail or projection X on which tho rack slides.

page_text: Ya spiral spring placed on the spindle to prevent movement of the worm
through vibration.
Although I bave described and shown in the Drawings the application of
this Invention whereby I am enabled to produce two pieces of cloth it will be
evident that the principle is capable of extension, and that two or moro pieces
may be woven in one loom. The Invention as here described and illustrated
shows the arrangement I prefer in applying the Invention to existing looms,
which is readily and economically effected.
Having thus fully described the nature and object of this my said Inven-
tion, with the manner in which tho samo is to bo or may be performed or
carried into practical effect, I would remark in conclusion that I claim as
my Invention and believe to be new within the realm, the construction and
arrangement of the apparatus as and for the purpose herein described and
illustrated in the Drawings, or any mero modification of the same.
In witness whereof, I, the said Adam Bullough, have hereunto set my
hand and seal, this Tenth day of June, in the year of our Lord One
thousand eight hundred and sixty-eight.
Witness,
JOSEPH BRIERLEY,
Civil Engineer,
