Year: 1873

page_text: LETTERS PATENT to Joseph Wood, of Batley Carr, in the County of
York, Overlooker, for the Invention of "IMPROVEMENTS IN LOOMS
FOR WEAVING WOOLLEN AND OTHER FABRICS."
Sealed the 31st October 1873, and dated the 9th May 1873.
PROVISIONAL SPECIFICATION left by the said Joseph Wood at the
Office of the Commissioners of Patents, with his Petition, on the
9th May 1873.
I, JOSEPH WOOD, of Batley Carr, in the County of York, Overlooker,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
LOOMS FOR WEAVING WOOLLEN AND OTHER FABRICS," to be as follows:-
The object of the Invention is to obtain simplicity with certainty in
working.
One part of the Invention relates to means for operating sliding
shuttle boxes. In effecting this part of the Invention the series of
sliding boxes at each end of the loom is connected to a pair of levers,
and when there are three box chambers in the series to be moved each

page_text: of these levers is provided with two surfaces, cither of which is capable of
being acted upon by a sliding tappet, and these surfaces are so applied
to these levers that when the tappet is slided into position to act on one
of them to one of the levers the one outer box is brought into a liuc
with the race of the batten, or when the tappet is slided into position to
act on the other surface of that lever it is also in position to act on a
corresponding surface of the other lever, and in so acting the middle box
chamber of the series of three will be brought into a line with the race
of the batten, and when the tappet is further shifted off the one lever
entirely and on to the other surface of the other lever the opposite
outer box chamber will be brought into a line with the race of the
batten. By this means positive motion to the boxes is obtained. The
sliding of the tappets on their shaft is effected by jacquard or other
suitable pattern surface. The series of boxes are held correctly in posi-
tion after selection by a spring lever with a series of projections on it,
such projections being capable of receiving between pairs of them a bowl
on a rocking holding lever.
Another part of the Invention relates to means by which the selection
of the order of picking is effected, and by which the picking motion may
be thrown out of gear at pleasure.
The selection of the order of picking is effected by one or the other
end of a rocking lever being brought by pattern motion between one
or other of a double end of lever operated by tappet motion and one or
other corresponding double end of a T lever acting to slide the bowls
into correct relative position.
The jacquard or lag or such like pattern cylinder is operated for rota-
tion and holding between times of rotation by a peg and stud wheels, or
such like means, and rotation at the times desired is given to the peg or
such like wheel by clawker or catch carried by a small lever carried by
another lever operated by a tappet, and in order to obtain a back motion
to the pattern surface employed, when desired this lever carrying the
clawker also carries another similar clawker capable of acting on the
peg wheel to give motion to it in the opposite direction a spring or
springs act to draw the clawkers towards the pin wheel, whilst a stop
prevents one or the other of them from such action according to the
position of the lever carrying these clawkers, and that position is
governed by a connecting rod from a handle or rocking lever. This
handle or rocking lever is also capable of turning as an axis, and is pro-

page_text: vided with an eccentric or arm or such like motion, in order that by a
partial rotation of this handle or rocking lever a weight may be taken
from one end of an L lever acting on a connecting rod to the shifting
picking bowl at one end of the loom so as to prevent that bowl from
being brought into position to be operated by its tappet when the
picking bowl at the other end of the loom is off its tappet, thereby
stopping the motion of both pickers. This handle or rocking lever is
applied to a shaft with an arm which by connecting means at the time
of reversing the motion of the peg wheel above referred to also slides
a connecting rod to the tappet motion on a ▲ lever so as to reverse the
motion of the pickers. A separate divided lever is applied to the axis
of the pin wheel, the outer portion of which lever is formed at its
junction with the inner portion thereof, with a pair of drivers so that
by rocking this outer portion in one or other direction, motion in a
corresponding direction may be given to the pin or such like wheel, to
give motion thereto in cither direction when the loom is not being
driven by power.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Wood in the Great Seal Patent Office on
the 7th November 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPп
WOOD, of Batley Carr, in the County of York, Overlooker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of May, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Joseph Wood, Her special license
that I, the said Joseph Wood, my executors, administrators, and
assigns, or such others as I, the said Joseph Wood, 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, the

page_text: Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
LOOMS FOR WEAVING WOOLLEN AND OTHER FABRICS," upon the condition
(amongst others) that I, the said Joseph Wood, my executors or
administrators, by an instrument in writing under my, or their, or one
of their hands and seals, 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 Letters Patent.
NOW KNOW YE, that I, the said Joseph Wood, do hereby declare
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement thereof, that is to say:—
The object of the Invention is to obtain simplicity with certainty in
working. The first part of the Invention relates to means for operating
sliding shuttle boxes. In effecting this part of the Invention the series
of sliding boxes at each end of the loom is connected to a pair of levers,
and when there are three box chambers in the series to be moved each of
these levers is provided with two surfaces, either of which is capable of
being acted upon by a sliding tappet, and these surfaces are so applied
to these levers that when the tappet is slided into position to act on one
of them to one of the levers the one outer box is brought into a line
with the race of the batten, or when the tappet is slided into position to
act on the other surface of that lever it is also in position to act on a
corresponding surface of the other lever, and in so acting the middle box
chamber of the series of three will be brought into a line with the race
of the batten, and when the tappet is further shifted off the one lever
entirely and on to the other surface of the other lever the opposite outer
box chamber will be brought into a line with the race of the batten.
By these means positive motion to the boxes is obtained. The sliding of
the tappets on their shaft is effected by jacquard or other suitable pattern
surface. The series of boxes are held correctly in position after selection.
The second part of the Invention relates to means by which the
selection of the order of picking is effected, and by which the picking
motion may be thrown out of gear at pleasure.
The selection of the order of picking is effected by one or the other
end of a rocking lever being brought by pattern motion between the one
=

page_text: or other part of the double end of a lever operated by tappet motion and
one or other corresponding double end of a T lever acting to slide the
bowls into correct relative position.
Thirdly, the improvements relate to means for operating with the
jacquard or lag or such like pattern cylinder.
The jacquard or lag or such like pattorn cylinder is operated for
rotation and holding between times of rotation by a peg and star wheels
or such like means, and rotation at the times desired is given to the peg
or such like wheel by clawker or catch carried by a small lever carried
by another lever operated by a tappet, and in order to obtain a back
motion to the pattern surface employed when desired this lever carrying
the clawker also carries another similar clawker capable of acting on the
peg wheel to give motion to it in the opposite direction, a spring or
springs act to draw the clawkers towards the pin wheel, whilst a stop
prevents one or the other of them from such action according to the
position of the lever carrying these clawkers, and that position is governed
by a connecting rod from a handle or rocking lever. This handle or
rocking lever is also capable of turning as an axis and is provided with
an eccentric or arm or such like motion in order that by a partial
rotation of this handle or rocking lever a weight may be taken from one
end of an L lever acting on a connecting rod to the shifting picking
bowl at one end of the loom, so as to prevent that bowl from being
brought into position to be operated by its tappet when the picking
bowl at the other end of the loom is off its tappet, thereby stopping the
motion of both pickers. This handle or rocking lever is applied to a
shaft with an arm, which, by connecting means at the time of reversing
the motion of the pcg wheel above referred to, also slides a connecting
rod to the tappet motion on a 1 lever so as to reverse the motion of
the pickers.
But that the Invention may be fully understood I will by the aid of

page_text: their construction may be better understood. In each of the views the
same letters and figures indicate corresponding parts.
.
a, a, indicates the outline of the framing; is the crank shaft, which
receives motion from a steam engine or other power, operating by a strap
or band acting on a drum or pulley applied to that shaft in the
ordinary manner, but which I have not thought it necessary to show;
c indicates the shifting shuttle boxes, with three chambers, c¹, c², c³.
This box c is suspended by the link & from one end of the lever e, which
is supported, with capability. of rocking on the axis e¹, carried by
a bracket a¹ from the main framing, and it its other end this lever e
carries a counterbalance weight e² to counterbalance the weight of the
shuttle box c. To the lever e are connected by pin joints f¹ and g¹ the
upper ends of connecting rods fand g. The lower end of the connect-
ing rod is by pin joint f* connected to the outer end of the lever h,
which is supported to turn on the axis ', carried by the bracket a³, and
this lever his formed with two steps and ³, one of which (") is
adjustable by set screw . Either of these steps and ³ is capable
of being operated upon by the cam or tappet i in its revolution with the
shaft b, as that tappet is slided into position for the purpose, and in
order to enable this tappet to be thus slided it is formed to slide on
a fin or feather applied to the shaft or axis b. The other connecting
rody is at its lower end in like manner connected by a ping to the
outer end of a lever j, which is supported to turn on a pin carried by
the bracket a. This lever also, like the lover h, is formed with two steps
and . The step is adjustable on the lever j by the set screw j',
and the tappet or cam i is capable of being brought into position to
act on either of these steps j³ or j³. When the tappet or cam i is
brought into position to act on the step the shuttle box c will
be lowered so as to bring the shuttle chamber c¹ into a line with the
shuttle race to receive a shuttle or to have one thrown therefrom. When
thic cam or tappet i is moved to act on the step the lever j will be
operated to raise the shuttle box c, so that the shuttle chamber c³ will
be placed in a line with the race to receive a shuttle or have one thrown
therefrom by the picker motion. When the cam or tappet i is moved
so as to act simultaneously on both the steps and the shuttle box c
will be operated by the lever e, so as to bring the central chamber
thereof c² in a line with the race so as to receive a shuttle or have onc
shot therefrom by the picking motion. The sliding motion of the cam

proceed to describe the second part of my Invention.

page_text: retaining the jacquard or pattern cylinder n" between the changes. An
arm from the axis I of the lever I hereafter more particularly
referred to is connected by the rod with the rod n³, so as to slide the
pin n³ into the centre of the groove in the lever n*, and prevent the action
of either end of the lever n when the lever 1 is in a central position.
The ends of the rocking lever » are either of them capable of being
brought by the pattern surface into position between one of the double
ends m³ of the lever mand ono or the other end o' or o³ of the L lever o
which turns upon a fixed stud o³, and at its end o' is forked to admit of
the end of the rod p passing through it and allow of that end of the lever o
acting either on the nut p¹ carried by that rod 2 or on the nut or stud q.
The rod p is connected to the picking bowl at one end of the loom, and
this rod p is acted upon with a tendency to keep that bowl free of its
tappet by means of the weighted lever which turns upon a centre of
motion », and at one end is forked to embrace the rod p between the
nuts p' and p³, whilst the other end of it is weighted with a weight 1².
The nut q acts when operated upon by the end of of the lever o to
shift the bowl for the picking at the opposite end of the loom. The
weighted end of the lever is capable of being raised to actuate the
rodas hereafter referred to.

I will now describe the third part of the Invention which is represented
applied in the end and front views of the parts of a loom at Figures S
and 9. In this case also the letters a, a, indicate the framing, and 6 the
main or crank shaft. In this case the axis A¹ of the jacquard or lag or
such like pattern cylinder A. has applied to it the star wheel A³, which
is operated to cause its rotation at the times and in the order desired
by pegs B' in the plate B, and rotation to this plate B at the times
desired and in one direction is obtained by the catch or clawker end C'
of the lever C, and this lever C is carried so as to be capable of a rocking
motion on the pin C³, carried by one end of the lever D, which turns
upon the fixed stud D', and at its other end is attached by pin joint D³
to the upper end of the adjustable connecting rod E, the lower end of
which is attached by pin joint E¹ to one end of the lever F, which is
capable of turning on the fixed stud F, and is operated for motion to
it by a cam or tappet F on the shaft or axis b. A spring G acts with
a tendency to draw the clawker or catch C¹ to the pegs B³ of the plate
wheel B, but when it is desired to obtain a back motion to the parts
the clawker or catch C³ also formed on a fork of the lever C may
brought into position to act on the pins B³ of the plate B by the
bc

page_text: action of the spring connecting rod H, one end of which is connected
to the lower end of the lever C, and the other end of it to the lever I,
by that lever being turned on its axis of motion I' to bring it in a linc
with the notch or stop I in the segmental guide plate Is. Or the lever
I may be held so that both clawker ends C and C³ may be free of the
pegs
B of the plate B by the lever I being held by a central notch or
stop I in the plate I³. This handle or rocking lever I also carries a
small shaft J, which is capable of turning in bearings provided for it
on the lever I, and this shaft J has at ouc end formed on or applied to
it a handle J', and at the other end an arm, or it may be an eccentric J*,
which by a connecting rod J³ (see Figures 4 and 5) is connected to onc
end of the L lever J which turns on a fixed stud J, and at its other
cud is by the connecting rod Jª connected to the weighted end of the
lever 1.
Thus by a partial rotation of the shaft or axis J the effect of
the weight may be removed.
Having thus described my Invention, and means which I adopt in
carrying the same into effect, I would have it understood that I do not
confine myself to the precise details shown and described, as the same
may be varied without departing from the peculiar character of my.
Invention, but what I do claim is,—
First. The adaptation or combination of means for operating shifting
shuttle boxes substantially as described.
Secondly. I claim the adaptation or combination of means for
obtaining changes in the order of picking substantially as described.
Thirdly. I claim the adaptation or combination of means operating
with the jacquard or lag or other pattern cylinder substantially as
described.
In witness whereof, I, the said Joseph Wood, have hereunto set my
hand and scal, this Fifth day of November, in the year of our
Lord One thousand eight hundred and seventy-three
