page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HUGH
COGAN, Merchant and Manufacturer, of West George Street, Glasgow, in the
County of Lanark, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent under the Great Seal, bearing date the Twelfth day of July, Eighteen
hundred and forty-five, in the ninth year of Her reign, did, for Herself, Her.
heirs and successors, give and grant unto me, the said Hugh Cogan, my;
exors, adñors, and assigns, Her special license, full power, sole privilege.
and authority, that I, the said Hugh Cogan, my exors, adññors, and assigns,
and every of them, by myself and themselves, or by my or their deputy or
deputies, servants or agents, or such others as I or they should at any time
agree with, and no others, from time to time and at all times thereafter,
during the term of years therein expressed, should and lawfully might make,
use, exercise, and vend, within that part of Her said. Majesty's United King-
dom of Great Britain and Ireland called England, Her Dominion of. Wales,
and Town of Berwick-upon-Tweed, in such manner as to me, my exors,
adors, or assigns, or any of them, should in my or their discretion seem
meet, my Invention of "AN IMPROVED METHOD OK METHODS FOR WEAVING IN.
PATTERNS, OR VARIOUS COLOURS, OR FABRICS;" in which said Letters Patent there.
is contained a proviso, that I, the said Hugh Cogan, should particularly describe.
and ascertain the nature of said Invention, and in what manner the same is:

page_text: to be performed, by an instrument in writing under my hand and seal, and
cause the same to be enrolled.in Her Majesty's High Court of Chancery
within six callendar months next and immediately after the date of said
Letters Patent, as in and by the same, reference being thereunto had, will more
fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
IIugh Cogan, do hereby declare that the nature of my said Invention, and
the manner in which the same may be performed, are particularly described
and ascertained in and by the following description thereof, reference being
had to the Drawings hereunto annexed, and to the figures and letters marked
thereon, that is to say:-
My Invention consists in an improved method or methods of raising and
lowering the shuttle box or boxes of power looms, by means of a wheel, levers,
and apparatus therewith connected, worked and regulated in connection with
the loom, whereby one, two, or more shuttles may be used in the same loom
in such successive order and for such number of shots at a time as may be
required for the fabric or pattern desired to be woven.
The said Invention may be practically applied and used in manner follow-
sing:―
Figure 1. is the front view, and Figure II. is the side view, of a power
loom. A is the lay; B is the frame; C is the driving pully or wheel; D is
a spur wheel, fixed to the pulley shaft, and drives the wyper shaft wheel E,
by which the power is communicated to the ordinary power loom for working
the treadles and heddles, and driving the shuttle. Neither D nor E are shewn'
on Figure I. The foregoing are not claimed as parts of my Invention.
The following is a description of an apparatus by which my Invention may be
practically applied and used :-F is a spur or pinion wheel fixed to the end of
the wyper shaft, which wheel F drives another spur wheel, the outer edge of
which is shewn by the dotted line G on Figure II., and is marked G on Figure
I., the spindle of which revolves on journals H; I is a broad wheel (called the
box wheel), fixed to the same spindle as G, and revolving with G, and having
on either or both sides thereof projections or studs K, (which to avoid friction
may be made to revolve) and the number of which will depend on the pattern
or the fabric to be woven. The frame or rim of the box wheel I may be so.
constructed as to allow the studs to be moved to any part thereof. L, l, are
levers (working on a pivot M), turned up at the one end, where they are acted
on by the studs K on wheel I, and which levers are connected at the other
end by the joints N, n, with the rods 0, o; P is a catch lever, having a pro-

page_text: jection V, connected with O by the joint Q, and which lever is joined to the
connecting rod R, and the catch lever S (having a projection V thereon), the
end of which lever S works in a stud T. The projections V support the shuttle
box U (which contains one or more shuttles Z), after being raised up by the
rod W, after described. Y is the bottom of the frame of the shuttle box. The
shuttle box is shewn on Figure I., with the (front) front thereof removed, so
as to shew the shuttles. W is a rod, attached to the bottom of the shuttle
box, connected with o by the joint X, and which is acted upon by the lever.
1, r, are rods, on which the shuttle box works up and down. The action of
rod W raises the shuttle box, and the action of levers P and S causes by its
movements the shuttle box alternately to be caught and supported by the pro-
jections V, and to be lowered to the level allowed by rod W when depressed,
and thus by the alternate action of levers L, l, on the rods O, o, the shuttles
are changed, so that according to the number of studs on wheel I, and the
number of teeth on the pinion wheel F and on the spur wheel G, (or all, or
one, or more thereof) the use of the required number of shuttles, two or more,
and the number of shotts of each shuttle at a time required for weaving the
particular pattern or fabric desired is attained.
1 is a weft protector, which is not claimed as a part of my Invention; 2 is a
lever, bearing on the protector, and fixed to the ends of rod 3, to the other
end of which a lever 4 is fixed, and which lover 4 is connected by a joint 6 to'
rod 5, the lower end of which is attached to a lever 7, fixed upon a shaft 8
working on the side of the loom. 9. is a forked lever, fixed to the shaft 8, and
working into a circular clutch box 10. The effect of this apparatus is, that
by the action of the weft protector (occasioned by the breaking of the weft
thread) the lever 2 acting on the rods and levers with which it is connected,
throws the clutch box out of gear, and it is not thrown into gear again till
acted on by the spiral spring 11 (or by a weight), and thus the motion of box
wheel I is stopped for two shotts or less, thereby making up for the shot or
shotts which would otherwise not have been thrown by the weft thread
breaking.
I claim right to use either the whole or any part or parts of my Invention
and apparatus described, separately or altogether.
In conclusion, I remark generally that the apparatus and machinery before
described is fitted for the application of my Invention to practical use, but I do not
limit myself to the manner, plans, apparatus, or combinatious, before described
or shewn, to effect the object of the Invention, or the manner of communicating
action to the said wheels, levers, rods, and others; and I reserve right to effect

page_text: e object of my Invention by such other plans, apparatus, and combinations
may be practically applied and used.
In witness whereof, I have subscribed and hereby subscribe my name
and set my hand and seal to these Presents, written on this sheet of
paper duly stamped, by Robert Meldrum, Clerk to Robert Reid and
William Towers, Writers, in Glasgow, at Glasgow, the Seventh day
of January, in the year of our Lord One thousand eight hundred and
forty-six, before these Witnesses, John Fife, Clerk to the said Robert
Reid and William Towers, and the said Robert Meldrum..
