page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ARTHUR
ELLIOTT, Machine Maker, of Manchester, in the County of Lancaster, and
HENRY HEYS, of the same place, Book-keeper, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent under the Great Seal of Great Britain, bearing date at Westminster,
the First day of June, in the thirteenth year of Her reign, and in the year
of our Lord One thousand eight hundred and fifty, did give and grant unto
us, the said Arthur Elliott and Henry Heys, our exors, adñiors, and assigns,
Her especial licence, full power, sole privilege and authority, that we, the
said Arthur Elliott and Henry Heys, our exors, adñiors, and assigns, and
such others as we, the said Arthur Elliott and Henry Heys, our exors, adiñors,
and assigns, should at any time agree with, and no others, from time to time
and at all times during the term of years therein expressed, should and
lawfully might make, use, exercise, and vend, within that part of Great.
Britain and Ireland called England, Her Dominion of Wales, and the Town
of Berwick-upon-Tweed, and also in Her Islands of Jersey, Guernsey, Alder-
ney, Sark, and Man, and in all Her Majesty's Colonies and Plantations
abroad, our Invention of "CERTAIN IMPROVEMENTS IN MACHINERY FOR MANU-
PACTURING WOVEN FABRICS;" in which said Letters Patent there is contained
a proviso that we, the said Arthur Elliott and Henry Heys, or one of us,
shall cause a particular description of the nature of our said Invention,
and in what manner the same is to be performed, by an instrument in writing
under the hand and seal of one or both of us, to be enrolled in Her Majesty's
High Court of Chancery within six calendar months next immediately after

page_text: the late of the said in part recited Letters Patent, as, reference being there-
unto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
Arthur Elliott and Henry Heys, do hereby declare that the nature of our
said Invention, and the manner in which the same is to be performed and
carried into effect, is particularly set forth, described, and ascertained in and
by the following description or Specification, reference being had to the
Drawings hereto annexed, the Figures on which Drawings are progressively
numbered, and the letters, indices, or references employed to indicate any
particular part or parts of our improvements are also made use of to repre-
sent the same part or parts in other Figures when different views thereof are
shown.
Our said Invention relates to improvements in that description of machinery
commonly known by the name of looms, which are worked either by hand or
power to weave or manufacture "woven fabrics." The novelty of which
consists,―
Firstly, in the arrangement and construction of certain apparatus, which is
fixed to certain parts or portions of the loom, for the purpose of preventing the
shuttle flying off the race or trash board when in the actual operation of
weaving, to the great danger of persons employed in such operation.
Secondly, in an improvement or addition of a clip or stop to the present
trap motion, by which the ends or threads of the warp are prevented from
being broken, or, in other words, to prevent what is technically called trapping
in the shed.
Thirdly, in the construction, arrangement, and mode of operation of a spring
apparatus attached to the inside of the shuttle box of the loom, which is
worked either with or without the ordinary swell, for the purpose of preventing
any rebounding or reaction of motion of the shuttle in the box after the pick
has been made, and freeing it from pressure to enable the pick to be made;
the whole of which apparatus and improvements, and their practical application,
are explained in the following description, and illustrated in the Drawings, in
which description we do not explain the working of those ordinary parts of
the loom which are not in connection with or bear upon our said Invention,
as such working will be readily understood by those conversant with weaving.
The advantages of our said Invention consist in the construction and
arrangement of certain apparatus to several parts or portions of the loom, for
the purpose of preventing accidents to persons employed in the weaving
process, saving or economising time and material, producing superior fabrics

page_text: than those ordinarily manufactured from similar materials, and rendering the
operation of weaving fibrous materials safer, more simple, and much cheaper.
Our arrangements for preventing the shuttle flying off the race or trasḥ
board are shewn in Figs. 1, 2, and 3.
Figs. 1 and 3 represent a section of part of a loom called the slay or
lathe, with our guides or guards. Fig. 2, a front view of the same, shewing
our guides or guards fixed to a cross bar on the slay or lathe top, with the
necessary apparatus for working the same. Fig. 4, a plan of the same,
shewing more plainly our spring apparatus in the shuttle box; and Fig. 5 a
side and front view of the guide or guard, which in these Figures are drawn to
the full size requisite for ordinary-sized shuttles. a represents the shuttle;
b, the shuttle boxes; c, the race or trash board on which the shuttle slides
from end to end in the process of weaving; d, the slay or lathe top; e, the
lathe swords; f, a cross bar or rod which is fixed to the lathe swords e by
fixings, to which are fixed or attached our guides or guards, which may be let
in or sunk to the shoulder, as shewn in Fig. 5, and rivetted or screwed to the
said cross bar or rod, or fastened in any other convenient or suitable manner.
This cross bar or rod may be made of iron, steel, brass, wood, or any suitable
metal or material. g, a handle to lift up the said cross bar or rod, when
required, for the purpose of taking out the shuttle; g', a fixing by which the
said cross bar or rod is attached and held to the lathe swords; g², a spring
which keeps or holds the said cross bar or rod in the requisite position when
lifted up, and also keeps or maintains it in its proper position when down, and
enables it to resist any pressure the shuttle may in its rapid movements bring
in contact with it; 9³, a stop pin fixed to the said cross bar or rod, to prevent
it coming in contact with the reed when let down; the said fixings, spring,
and stop pin may be made of iron, steel, brass, wood, or any suitable metal or
material; h, guides or guards fastened to the aforesaid cross bar or rod as
before described, the extreme points of which are so arranged and adjusted as
to extend over the outside or any other convenient part of the shuttle, to pre-.
vent its escaping or flying off the race or trash board during its rapid movements
in the process of weaving. These guides or guards may be made of iron, steel,
brass, wood, or any suitable metal or material, but must be carefully smoothed,
polished, or burnished at the bottom edges, or those parts of them which may
come in contact with the shuttle or warp threads, to prevent cutting or fraying
them. These guides or guards may be placed at any convenient distance
asunder, as experience will suggest; but from one to two inches has been
found to answer extremely well. i represents a spring made of steel, or
any suitable metal or material, which is attached to the inner part of the

page_text: shuttle box b, and is worked with or without the common or ordinary swell,
which, by pressing or tightening the shuttle on its arrival in the shuttle box,
prevents its rebounding.
Fig. 6 represents a side view of part of a loom, shewing the frog or stop
motion, with our additional clip or stop apparatus out of gear; Fig. 7 the
same, with our clip or stop apparatus in gear; and Fig. 8 a plan of the same.
These Figures shew another of our said improvements in looms, the purport of
which is to prevent what is technically termed trapping in the shed, by which
the ends or threads of the warp are broken. k represents the frog, which may
be made and constructed in the usual manner, or may be stationary, sliding,
or fixed, in any convenient manner or position; ', the notch of the same; k²,
the slide catch; 1, the stop rod finger; and m, a clip or stop made of iron,
steel, or any suitable metal or material, and is fastened to the side, or in any
other convenient position of the loom, which, when the stop rod finger falls
upon the slide catch or the notch of the frog ', this clip or stop rises
simultaneously with the motion of the slide catch or the slide frog, and clips
the stop rod finger to prevent it slipping or rising from the notch of the frog,
thus making the operation certain, and preventing trapping in the shed.
Having now fully described the nature and particulars of our said Inven-
tion, and the mode of carrying the same into practical effect, we wish it to be
distinctly understood that we do not claim any of the parts of looms exhibited
in connexion with our said improvements, except in so far as they or any of
them are indispensable for and in working out our improvements; but we
claim,―
Firstly, the arrangement and construction of the apparatus described and
illustrated in the annexed Drawings with figures, number, and reference, or
any modification thereof, for preventing the shuttle flying off the race or trash
board.
Secondly, an improvement or addition of a clip or stop apparatus to the
trap motion, to prevent trapping in the shed; and,
Thirdly, an additional spring apparatus to the inside of the shuttle box, to
prevent the shuttle rebounding.
In witness whereof, we, the said Arthur Elliott and Henry Heys, have
hereunto set our hands and scals, this Twenty-eighth day of Novem
ber, in the year of our Lord One thousand eight hundred and fifty.
