IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1863

page_text: LETTERS PATENT to William Whiteley, of the Prospect Iron Works,
Lockwood, in the County of York, Iron and Brass Founder and
Machinist, for the Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING."
PROVISIONAL SPECIFICATION left by the said William Whiteley at
the Office of the Commissioners of Patents, with his Petition, on the.
12th May 1868.
I, WILLIAM WHITELEY, of the Prospect Iron Works, Lockwood, in the
County of York, Iron and Brass Founder and Machinist, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING,"
to be as follows:-
This Invention relates to looms where two or more shuttles are employed,
and consists in arranging and applying the mechanism or apparatus in con-
junction with a jacquard machine, so that the loom will be self-acting in the
production of the various figures or designs required in the fabric. The im-
provements have reference more particularly to the box motion of the loom, the
shuttle boxes being acted upon by the lifting and sinking bars of the jacquard,
which bars are made to project through the frame of the jacquard, and act
upon hooks and levers connected directly to the shuttle boxes. By this mode
of arranging the mechanism the boxes are raised or lowered as required by the
jacquard itself, in place of the jacquard being made to govern a special
mechanism for lifting the boxes. It is further proposed to adapt a reversing

page_text: motion to the cylinder of the jacquard, whereby the shuttles are made to
return to their former position without disconnecting the boxes and jacquard,
and consequently their relative positions to each other are always main-
tained.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Whiteley in the Great Seal Patent Office on the
12th November 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WHITELEY, of the Prospect Iron Works, Lockwood, in the County of York,
Iron and Brass Founder and Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of May, in the year of our Lord One
thousand eight hundred and sixty-three, in the twenty-sixth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William Whiteley, Her special license, that I, the said William Whiteley,
my executors, administrators, and assigns, or such others as I, the said
William Whiteley, my executors, administrators, or 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 I, the said William
Whiteley, my executors or administrators, by an instrument in writing under
my hand and seal, or under the hand and seal of one of them, should particu-
larly describe and ascertain the nature of the said Invention, and in what
manner the saine 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' William Whiteley, 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, reference being had to the accompanying Drawings and to the
letters and figures marked 'thereon, that is to say :-
My said Invention relates to looms where two or more shuttles are
employed, and consists in arranging and applying the mechanism or apparatus
. in conjunction with a jacquard machine, so that the loom will be self-acting in

page_text: the production of the various figures or designs required in the fabric. The
improvements have reference more particularly to the box motion of the loom,
the shuttle, boxes being acted upon by the lifting and sinking bars of the
jacquard, which bars are made to project through the frame of the jacquard,
and act upon hooks and levers connected directly to the shuttle boxes. By this
mode of arranging the mechanism of the boxes they are raised or lowered as
required by the jacquard itself, in place of the jacquard being made to govern
a special mechanism for lifting the boxes. It is further proposed to adapt a
reversing motion to the cylinder of the jacquard, whereby the shuttles are
made to return to their former position without disconnecting the boxes and
jacquard, and consequently their relative positions to each other are always
maintained.
And in order that my said Invention may be fully understood, I shall now
proceed more particularly to describe the same, and for that purpose. I shall
refer to the several Figures on the Sheets of Drawings hereunto annexed, the
saine letters of reference indicating corresponding parts in all the corresponding
Figures.
Figure 1, on Sheet 1 of my Drawings, is a front elevation of an ordinary
woollen loom with my improvements applied thereto; and Figure 2, on Sheet.2,
is an end elevation of the same; Figure 3 is a front elevation of a portion of
a jacquard drawn to a larger scale; Figure 4 is an end view, and Figure 5 is
a plan, of the same.
There are two shuttle boxes at one end of the same, marke: A, and three at
the other marked B. The two boxes are actuated by a rod C looped on to
one end of a lever D, which works on a centre D' on the top rail of the loom,
the other end of the said lever being jointed to a booked rod E, which passes
through a needle E¹ (Figure 5), and is capable of taking on to one or other of
.the two lifting and sinking bars F, G, (which project through the frame of
the jacquard,) according to the arrangement of the pegs in the peg lags on the
cylinder of the jacquard. The three boxes at B are connected by a rod H to
one end of a bent lever I, which also works on a centre I' in the top rail of
the loom, and to the other end of which lever are fixed four adjustable lugs or
projections a, b, c, d. Two other levers J, K, are carried by the top rail and
work on the centre or fulcrum J', each of which has two adjustable studs and
friction rollers e, f, g,.h, fixed thereto, which are so set or arranged as to act
upon the lugs a, b, c, d, as required. The other ends of these levers are joinfed
..to hooked rods L, M, respectively, which engage with the lifting bars as they
are indicated and actuated by the peg lags on the cylinder N. It will be seen
.that the lever D is lifted by the bar F, and consequently the two boxes are in.

page_text: their lowest position, or the upper one of them in line with the shuttle race of
the lathe or batten O; but when the rod E is removed from contact with the
bar F by the action of the peg lags pushing the needle in, the said rod will
be sunk or depressed by the bar G, and consequently the said boxes will be
lifted to their highest position, or that the low box will be placed in line with
the shuttle race. It will also be seen that the three boxes are now in their
middle position, or the middle box in line with the shuttle race, and that the
rod L is hooked on and lifted by the bar F, the lever J being raised into its
highest position, and the stud 9 is in contact with the lug c on the lever I, also
that the lever K is in its lowest position by reason of the rod M being
removed out of contact with the bar F into contact with the bar G (by
means of the projecting peg P on the cylinder having pushed back the
needle Q, through the eye of which the rod M passes), (see Figure 5),
and the stud e is in contact with- the lug a; thus the two levers have com-
bined to place the boxes in this position. But suppose the lever J be lowered
to the position of K, the stud h would act upon the lug b, and lift that end
of the lever I and lower the boxes, until the top one would be in line with
the shuttle race; or, if the lever K be lifted to the position of J, the stud f
would act upon the lug d, depressing that end of the lever I, and so lift the
boxes, until the bottom one is brought into line with the shuttle race. These
stops and lugs are so adjusted on the levers as to produce the proper amount
of motion on the shuttle boxes. And in order that the said shuttle boxes may
be kept in proper position during the picking of the shuttles, a lever R
(Figure 2) is hinged on the loom, and having three arms, one of which is
attached by a rod S to the lever I, another is weighted so as to balance the
'boxes and levers, and the other carries a friction pulley T, which fits into any
of three recesses U, V, W, which are adjusted so as to place the shuttle boxes
in true position. The recesses are attached to a lever X, which is operated at
each pick by the tappet or cam Y, fixed on the crank shaft of the loom.
Figure 8, 4, and 5 are intended to shew more clearly the construction and
arrangement of the jacquard apparatus, and the adaptation of the reversing
'motion or the means of maintaining the relative positions of the shuttle boxes
and picking motion. A hand lever i is hinged to the top-rail of the loom, and
is weighted at k. A rod l'is jointed to the lever which connects it with the
ordinary hookers or catches m, n, which turn the cylinder and peg lags N.
To the lever i is attached another rod o, which is capable of sliding in the fixed
bracket p. In the top end of this rod is formed a slot o' (Figure 4) at an
angle or inclination to the line of motion thereof; the said slot clips or
embraces a needler, through which passes a hooked rods, which is connected

page_text: to a lever t, for actuating the picking motion. The hookers are here shown in
the reverse action, that is, the hooker n is in contact with the cylinder, but it
will be readily seen that if the hand lever i be lifted on to the latch or catch u
the hooker m will be lowered into contact with the cylinder ready for producing
direct action, when at the same time the rod O will be raised, and the slot o¹
therein will cause the needler to slide laterally, and will hold it in proper position
so as to come in contact with the proper line of pegs on the cylinder when in
play but on the reversing of the hookers, that is to say, on placing them as
now shown for reverse action, the said needles will be removed by the slot to
the position shown by the dotted lines in Figure 5, or out of contact with the
proper line of pegs, but into contact with another line which is suitably
arranged for this reverse action, whereby the relative positions of boxes and
picking motion will be always maintained.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried
into effect, I would observe, in conclusion, that what I consider to be novel
and original, and therefore claim as the Invention secured to me by the
herein-before in part recited Letters Patent, is,-
1st, the general construction, arrangement, and combination of mechanism
for actuating the drop or shuttle boxes of looms for weaving, substantially as.
herein-before described and illustrated by my Drawings.
2nd, the actuating of the drop or shuttle boxes of looms by means of hooks
and levers which are attached to the boxes, and are directly acted upon by
the lifting and sinking bars of a jacquard, substantially as herein-before
described.
3rd, the application and use of a reversing motion in combination with the
cylinder of a jacquard, whereby the shuttles are made to return to their former
position without disconnecting the boxes and jacquard, substantially as herein-
before described and illustrated by my Drawings.
In witness whereof, I, the said William Whiteley, have to this my
Specification set my hand and seal, this Eleventh day of November,
One thousand eight hundred and sixty-three.
WILLIAM WHITELEY. (L.S.)
