page_text: LETTERS PATENT to James Edward Hyde Andrew, of Audenshaw, in the
County of Lancaster, Machinist, for the Invention of CERTAIN IMPROVE.
MENTS IN LOOMS FOR WEAVING."
Sealed the 29th September 1865, and dated the 19th April 1865.
PROVISIONAL SPECIFICATION left by the said James Edward Hyde
Andrew at the Office of the Commissioners of Patents, with his Petition,
on the 19th April 1865.
1, JAMES EDWARD HYLE ANDREW, of Audenshaw, in the County of Lan-
caster, Machinist, do hereby declare the nature of the said Invention for
"CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
The first part of my Invention consists in the application of two series of
tuppets of different heights for governing the position of the shuttle box,
between these two series of tappets is a bar with an antifriction bowl, which
bar slides in a frame and is moved to and fro to bring the bowl in line with
the various tappets according to the shuttle box required by means of a
tappet chain or other equivalent, each tappet or pair of tappets always acting
on its corresponding compartiment of the shuttle box. The above combination
of tappets, bar with antifriction bowl and frame, is also applicable for varying
the position of the needle board, the pattern cylinder or other parts of looms
employed in producing different patterns or changes; or when similartappels
Price 1

page_text: are applied to act on bowls on each end of a lever or bar, the lever or bar is
made to slide in a frame oscillating on a centre when acted upon by the
tappets. This part of my Invention may be modified in several ways, as
follows: On the tappet shaft or other convenient shaft or stud I put an
external series of tappets, so thata bowl working on a stud or shaft connected
to a lever may be brought opposite any one of the tappets to act upon the
bowl, and thereby bring the lever into the position corresponding to the
height of the tappet which has acted on the bowl; to the above-mentioned
lever is attached another stud or shaft, on which works another bowl which is
slided simultaneously into position to be operated upon by any one of the
internalseries of tappets, to bring the lever intothesameposition as the external
tappets, or the internal tappet may be over the external tappet; the lever is
maintained in the position into which the tappets have brought it for any time
desired by a locking apparatus of the usual construction. Or a bar or lever
connected to the shuttle box, or for producing other changes, may be acted
upon by two plates with elevators and depressors, or graduated steps; the two
plates move from and towards each other from a fulcrum stud, or on
horizontal slides, and bring the bar or lever into the desired position for
varying the position of the shuttle box or for producing the other changes
required.
Secondly, my Invention relates to the shedding motion, and consists in
having two or more pattern cylinders and sets of cards one above the other, or
along side of each other, so that any cylinder and cards may be brought into
action when desired with the needles connected with the hooks for lifting the
warp threads, one set of cards or the cylinder only working the needles at one
time, the cylinders or cards out of action, or not employed in weaving their
respective patterns, are not allowed to revolve, but when desired begin again
at the same part of the pattern at which they left off; the cylinders are
provided with pinions or lock wheels which are turned round by a corre-
sponding pinion or pin wheel, the position of which is governed by any of the
apparatus above described for altering the position of the shuttle box, or by
ordinary tappets and levers, or pattern chains or barrels.
Thirdly, my Invention consists in dividing the needle board or the jacquard
cylinder, and the cards also if desirable, into sections, so that any sections or
divisions may be raised, lowered, or shunted to cause the corresponding
heddles to weave different patterns without altering or interfering with the
position or weaving effect of the other sections or divisions. Each section or
division is acted upon by a rod, shaft, or tappet put in motion by a chain or
other pattern surface.

page_text: Fourthly, my Invention consists in changing the position of the needle
board of jacquard machines or "dobbies "by means of two tappets, with two
or more corresponding litts on each, one of these tappets is connected with
the pattern chain, the two tappets are connected by a chain or other equi-
valent to make them act simultaneously, or a single tappet may be made to
act on a rod or lever connected to the needle board.
Fifthly, my Invention consists in driving the cylinders of jacquard machines
or dobbies" by means of a chain passing around a pulley on the fulcrum
shaft of the swing frame, and another pulley on the jacquard or "dobby
cylinder; the pulley on the swing frame shaft is driven by a star wheel
actuated from any convenient part of the loom, and the direction of motion of
the cylinder can be reversed by a double catch box gearing alternately when
desired into corresponding catch boxes fixed to bevel or lock wheels running
in opposite directions.
Sixthly, in an improvement ou previous Letters Patent granted to me on
the 9 April, 1862, No. 1007; this improvement consists in driving or turning
the small cam chain barrels (referred to in the third part of the Specification
of the said Letters Patent) from an intermittent or other wheel, or by a catch,
in such a manner that when a particular projection or projections on the main
chain shall pass over the barrel, it shall put the cam barrel into gear, so that
it will be turned one link, and thus according to the link of the cam chain
that has been brought up a corresponding row of pegs on the main pattern
chain will be brought into operation.
And, lastly, in placing the pegs or pattern surface on pattern chains in
different positions or rows, one behind the other, and making them of a
uniform or of different lengths or heights, or of different sizes; the pegs or
other surfaces are acted upon by feelers or other equivalents, so that each
series may be employed or connected to operate or indicate the changes
required for the particular motion or part of the loom with which it is in
communication.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Edward Hyde Andrew in the Great Seal Patent
Office on the 19th October 1865.

NOW KNOW YE, that I, the said James Edward Hyde Andrew, 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 (that is to say)
-
The nature of iny Invention consists, first, in various arrangements of two
series of tappets of different heights, and the parts acting in combination
therewith, for governing the position of the shuttle box, the needle board, the
pattern cylinders, and other working parts of the loom.
Secondly, in the application of graduated step levers, and the parts acting
in combination therewith, for governing the position of the shuttle box, the
needle board, the pattern cylinders, and other working parts of the loom.
Thirdly, in the application of a toothed or other suitable chain for turning
jacquard cylinders.
Fourthly, in an improved combination of machinery for turning and re-
versing the motion of the jacquard cylinder.
Fifthly, in a combination of machinery for varying the position of the needle
board, and locking the same when brought into position.
Sixthly, in dividing the needle board in sections and varying the position of
the same, to produce changes in the pattern.
Seventhly, in the application of two or more cylinders to a jacquard engine

page_text: or dobby, and the machinery for varying their position, for turning them
round, and by which their rotary motion is stopped when required.
Eighthly, in certain improvements upon the machinery described in the
Specification of Letters Patent granted to me on the Ninth day of April One
thousand eight hundred and sixty-two, Number 1007.
And, lastly, in a combination of machinery for changing the position of the
feelers to operate on different portions of the pattern chain.
And in order that my Invention may be fully understood, and readily
carried into operation, I will proceed to describe the two accompanying
Sheets of Drawings, reference being had to the figures and letters marked
thereon.
On Sheet 1. Figure 1 is an end view, and Figure 2 is a back view of a
loom to which parts of my improvements are applied; Figure 3 is a plan of
part of the saine. a is the crank shaft; b, the tappet shaft; c, the lay or
batten; c, the lay swords; c, the rocking shaft; d, a circular shuttle box,
containing in this instance six compartments, but more or less may be
employed; these and all the other parts requisite to complete the loom which
are not particularly referred to hereafter are made in any approved manner.
To the tappetshaft bis fixed the spir wheel, gearing into the wheelse' and f",
mounted respectively on the studs e and f. To these wheels are fixed or cast
the two series of tappets e and f, each series having six different heights,
corresponding to the number of compartments in the shuttle box; between
these two series of tappets is a bar g, with an antifriction bowl gl; this bar
slides laterally to and fro in the frame g, which vibrates on the fulcrum
stud g fixed to the loom side; the barg is guided by the red g3, and it is held
in position after it has been moved by the graduated step levers described
hereafter by a spring stud connected to the bar g, taking into V-shaped
recesses in the boss of the frame g, as shewn best in Figure 3. The outer
end of the frame g is connected by the link go to the endless toothed chain d',
which passes above around the toothed pulley de fixed on the axle of the
circular shuttle box d,and belowaround a similar pulleyc³ on theprolongationof
the rocking shaft c, or on a stud concentric with it; or a rack and pinion may
be used instead of the chain and pulleys described. The frame g' is counter-
balansed by the weight go, attached to a chain passing over a guide pulley.
A similar apparatus is also applicable for working a drop box with several
compartiments for the shutiles. To the crank shaft a is fixed a toothed
pulley al forgiving motion to the endless toothed chain h, which passes around
the toothed pulley 'loose on the shaft h2, but connected to it by a key and
groove; from a boss fixed to the shaft h² projects a stud taking into the slots

page_text: of the intermittent wheel i, to which is fixed the barrel of the double pattern
chain. The boss of the pulley has a groove, in which the end of the lever h
takes by moving this lever to and fro on its fulcrum, the chain barrel is
disconnected from the intermittent wheel i to enable the operator to move the
pattern by hand. One part of the pattern chain has links of four different
heights, corresponding to the number of changes required for the shedding
motion, and the other part has links of six different heights, corresponding to
the number of compartments in the shuttle box; these links may be placed
side by side, as shewn in the Drawing, or one behind the other, as shewn
detached in Figure 4. Above the fulcrum of the chain barrel are the two
feelers,, which are raised after every two picks by the cam h³ on the
shaft, acting on the lever j; the outer end of this lever passes under the
ends of the feelers 1, 2, which are guided in a slotted bracket . To the
feeler is jointed the upper end of the link , the lower end of which is
jointed to the catch, and to the feeler is jointed the link
below to the catch k³. The catches and are acted upon when required by
the graduated steps in the levers 1, 2, which receive a vibrating motion towards
and from each other by means of the tappet 4, shewn by dots in Figure 1 on
the shaft ²; this tappet acts on the lever m, connected by the link m' to the
horizontal arm of the three-armed lever m2, the vertical arms of which are
connected by the links m³ and m to the levers l, l. The catch is jointel to
the lever m, which is fixed to the shaft me, and the catch ³ is jointed to the
lever n, to which is also jointed the link n', which fits on a stud projecting
from the bar g above referred to.
connected
The mode of operation of these parts is as follows:-They are shewn in the
positions they occupy when the feeler j, j, are raised clear of the pattern
chain, and when the chain barrel is being turned round. As soon as the
chain is stationary the cam ³ permits the bowl of the lever j, and con-
sequently the feelers, to descend by their own gravity. If the links of the
chain are without elevators, both the catches & and drop below the level
of the graduated steps in the levers 7, . If the feeler is arrested in its
descent by a peg on the chain ¹, the catch is lowered to the level of the
corresponding step in the levers . ', which in approaching each other move
the lever ms, and thus produce the requisite change in the shedding motion,
as will be described hereafter; and if the feeler in descending is arrested in
its descent by a peg on the chain ', the catch 3 is held at the level of the
corresponding step in the levers 1, , which in approaching each other move
the lever n and link n' so as to traverse the bar g into the required position
for being acted upon by another pair of the series of tappets e and . The

page_text: barrel of the chain i may be worked like an ordinary jacquard cylinder, and
thus raise or move tho feclers,, into a position corresponding to the longth
of the pegs that have been brought forward. It is evident that when the bar g
is moved laterally the tappets e and fare in the position shewn by dotted
lines in Figure 1 to allow the bowl g¹ to pass. When the bar g has been
moved to its requisite position, the next revolution of the tappets e¹ and f
cause the shuttle box to move partly round in either direction, and thus bring
the desired shuttle in line with the shuttle race; and when the shuttle box
has been thus turned partly round it is held steady by a polygonal plate and
spring or other suitable locking apparatus, as in circular shuttle boxes of the
usual construction. By means of these improvements the shuttles may be
changed forwards or backwards in any required succession.
My improvements in the shedding motion are particularly applicable to
jacquard engines or " dobbies," and they are carried into operation in the
following manner:-o is the framing of an ordinary jacquard engine or
dobby; 7, the jacquard cylinder vibrating as usual in the swing frame p';
the jacquard cylinder is turned round by means of the shaft h', to which is
fixed the toothed pulley h; this pulley by means of a short toothed chain gives
motion to the pulley q' on the shaft g; at the other end of this shaft is fixed a
boss with a stud q2 taking into the intermittent wheel p², which rotates on a
stud; to the boss of the wheel p' is fixed or cast a small toothed pulley p³,
which, by means of a toothed chain p, gives motion to the pulley on the axle
of the jacquard cylinder p. The driving pulley p³ must be placed in such a
position that the oscillation of the jacquard cylinder does not cause the chain
to impart a partial rotary motion thereto. The pattern cards passing around
this cylinder have four or other convenient number of rows of holes for acting
on the needles o¹ passing through the needle board o², and this needle board is
moved up or down to bring the needles in line with any row of holes in the
cards in the following manner :-To the shaft m' is fixed the lever m², which
is connected by the link r to one end of the lever r³, the other end of which
is connected by the link to the needle board o'. When the position of
the lever m' has been changed by the action of the graduated steps levers l, l',
above described, a corresponding change is produced in the position of the
needle board, and the needle board is retained in its position by the spring
piece o³ in which are recesses corresponding to the number of rows of holes in
the jacquard cards; the needle board is connected by radius rods to the back
plate o, which vibrates on fixed studs as the needle board is moved up or
down. The needles o' pass as usual through the hooks o, to which the healds
are suspended; by this means a great number of changes in the pattern can

page_text: be produced with a comparatively sliort chain of cards, and by driving the
jacquard cylinder by means of the toothed chain p', it is turned round in either
direction with the loom.
I wish to remark that the positions of the bowl and the needle
board o may be varied by means of a tappet chain instead of the graduated
step levers, , above described, and the two series of tappets e² and f, with
the parts acting in combination therewith, may be adapted to vary the
position of the needle board, the pattern cylinder, and other working parts of
the loom.
'Figures 5 and 6 are two views of a modification of my improved arrange-
ment of tappets for changing the position of the shuttle box or for producing
the changes in the position of the needle board or other changes required, in
the loom. In this case the series of tappets e² are made internal and the
series of tappets are external. The bowl g' is acted upon by these tappets
in the manner described in reference to Figures 1, 2, and 3, to move up and
down the bar g, and the bowl is moved laterally so as to bring it in line with
the different heights of tappets by means of the lever gs, which vibrates on a
stud fixed in the bar g; this lever may be actuated by a pair of levers with
graduated steps as before described in reference to the levers marked 1, ', in
Figure 2, or by a tappet chain, or in any other convenient manner.
'I wish to observe that although I have only shewn tappets of three heights
in Figures 5 and 6, any other convenient number of heights may be employed,
and it is also evident that the tappets instead of being placed so as to act on a
single bowl as shewn, may be placed on opposite sides of the bar y and act
on separate bowls.
I
Figure 7 represents another modification of this part of my Invention. In
this arrangement the two series of tappets e, fi, are fixed on the tappet shaft b
and the bar g is open for the tappet shaft to pass through it. To the bar
are fixed studs for the bowls g', which are moved to and fro on the studs to
bring them in line with the required tappets by means of levers similar to g,
as shewn in Figures 5 and 6, or in any other convenient manner.
Figure 8 represents a modification of my improved machinery for driving
the cylinders of jacquard machines or "dobbies." aud q are two shafts
similar to those described in reference to Figures 1 and 2. To the shaft is
fixed a bevel pinion h, to which is cast a disc with a stud for working the
star wheel ? loose on the shaft q, but connected to it when in gear with
the clutch box q. The pinion h³ gears into the carrier pinion h, which drives
the pinion in the contrary direction to the pinion; the pinion ho is also
provided with a disc and stud for working the star wheel 94. The sliding

page_text: clutch box q is moved to and fro so as to bring it alternately in gear with the
clutches on the wheels q3 and q' by a lever actuated by a tappet chain or other
suitable meclianism. To the shaft q is fixed the mitre pinion gearing into
a similar pinion, to which is cast the toothed pulley p³ for driving the jacquard
cylinder p in either direction.
On Sheet 2, Figures 9 and 10 are two views representing the mode of
actuating the needle board o³ when it is divided into three parts. 0, 0, aro
the sides of the jacquard engine er dobby"; o', are the needles; o, the
back plaie; o, the hooks; and p, the jacquard cylinder. Each portion of
the needle board is connected by a link to the levers of, which vibrate on a
stud fixed to one of the sides o; to these levers are suspended the rods of, the
lower ends of which are actuated by a pattern chain, or by tappets, or by
graduated step levers similar to those marked 1, 1, in Figure 2. By raising or
lowering the various portions of the needle board the needles are brought in
line with different rows of holes in the jacquard card, and consequently a
change in the pattern is produced.
In Figure 9 I have shewn the needle board divided into three paris, but it
may be divided into more or less parts.
This part of my Invention may be
modified by shunting or moving laterally the various parts of the needle board
as shewn by dotted lines in Figure 9. To effect this each portion is jointed
to an elbow lever of, which must be actuated in the same manner as the
levers of above described.
Figures 11 and 12 are two views representing how two or mere jacquard
cylinders and sets of pattern cards may be worked in combination with a
jacquard engine or dobby of the usual construction, or constructed accord-
ing to any of the improvements herein-before described. In this instance I
have shewn four jacquard cylinders p placed one above the other, but the
number and position may be varied; the axles of the cylinders revolve in
bearings, which are moved up or down in slots in the swing frame pl, by
hand or by tappets, pattern chain, or other self-acting mechanism, acting on
the lever po, shewn by dotted lines. Each cylinder p is turned partly round
when required by the toothed chain pt passing below around the pulley p³,
as shewn and described in reference to Figure 2, and above over the small
pulley po, which is cast with the plate p, the studs in which take into the star
wheel p, a similar star wheel is fixed to the axle of each cylinder as shewn in
Figure 11. When the bearings p³ have been raised or lowered they are
retained in position by the circular portion of the plate p fitting in a recess
on one side of the bearing, as shewn in Figure 12. When changing the
position of the bearings p³ the plate p' is moved laterally on the axle to allow

page_text: the locking projections to pass; the spring p³ bringing the plate back to its
proper working position, or the stud plate p' may be moved in the direction
of the arrow in Figure 12. The jacquard cylinders when turned partly round
are each held secure by a locking stud as usual. In Figure 11 two of the
square plates against which these locking studs act are shewn to the right
hand end of the cylinders, and the other two are supposed to be at the left
hand side of the other cylinders. By this means any cylinder with its jacquard
cards may be brought into action wheu desired with the needles connected to
he hooks for lifting the selected warp threads for forming the shed, one
cylinder and one set of cards only working at a time, the others remaining
inactive, but when desired each cylinder and card begins again at the same
part of the pattern at which it left off; or any two or more of the jacquard
cylinders may be connected by wheels or other gearing, or they may be turned
by catches.
1.1.
Figure 13 represents the side of a loom to which a modification. of my
improvements in working the shuttle box is applied; in this view the shuttle
box d is made with three compartments, and it is worked upor down by means
of the graduated step lovers 1, 1, which are opened, and closed. by the
tappets 62, 63, fixed on the tappet shaft 6, the steps of the levers 1, P, act on a
catch projecting from the vertical arm of the elbow levers, which vibrates on
a stud fixed to the lever t; this lever vibrates on the fulcrum.'; to the outer
end of the levert is jointed the rod t2, the upper end of which is attached
to the drop box d, the weight of which is counterbalanced by the weight 13.
The end of the lever takes into recesses in the spring, locking lever t, by
which each compartment of the shuttle box is held alternately in line with
the shuttle race. The horizontal arm of the elbow levers is raised or lowered
to bring the catch in line with the required step of the levers.,, by a pattern
chain similar to that marked in Figure 1, or by tappets or other equivalents
acting on the rod ; it is evident that the position of the elbow levers must
be changed when the graduated step levers are open, the closing of the step
levers producing the required change in the position of the drop box,as before
described.
Figures 14 and 15 represent another of my improved combinations of
machinery for working the drop box; e and fare two series of tappets
acting respectively on the bowls g' and go, the axles of which pass through
the forked ends of the barg, and through the frame g, both of which vibrate
on a centre shaft or stud. The end of the frame g4 is connected by the link t
to the lever, the outer end of which is connected by the rod t to the drop
box d, as shewn in Figure 13. The lever t is locked in the manner above

page_text: described in reference to Figure 13. The position of the bar gis changed so
as to bring the bowls gl and glo,in line with the various heights of tappets by
levers and rods actuated by a tappet chain or other equivalent.
Figures 16, 17, and 18 represent my improvements in working parts of
the looms described in the Specification of former Letters Patent granted to
me on the Ninth day of April, One thousand eight hundred and sixty-two,
Nuinber 1007.
, is the pattern chain, and f, the lifter on the shaft m, on this shaft is the
sliding toothed bossj; on the edge of the chain a is a stud to raise the lever.r
the lever is connected by the link a to the elbow lever, which moves the
disc y to bring the stud'projecting from it in gear with the intermittent wheely',
the boss of which forms the barrel for the tappet chain s. This chain acts on
the lever connected by the link y³ to the elbow lever y', the vertical arm of
which takes into a groove in the sliding toothed boss i. By this means the
lateral position of the toothed boss jis governed by the height of the tappet
of the chains, thus bringing the toothed boss in line with any series of pegs
on the pattern chain a.
Figures 19, 20, and 21 represent a combination of the improvements de-
scribed in reference to Figures 16, 17, and 18, and the chain marked ¹ in
Figures 1 and 4.
The chain barrel w is supported in a swing frame, which is moved up and
down like a jacquard cylinder, the links of the chain ? passing over the
barrel w act on the levers w¹, to the ends of which the links w² are jointed;
these links are also jointed to the horizontal arms of the double elbow lever w³,
the vertical arm of which is connected by a rod to a slotted bracket, similar
to in Figures 1 and 2. By this arrangement when the position of the
double elbow lever w³ has been varied by the pegs on the links of the chain i¹,
the slutted bracket j', above referred to, is moved laterally, so ag to bring the
feelers in line with other rows of pegs, thus producing a great range of
pattern. The chain barrel w is turned partly round when required by a peg
on the edge of the pattern chain, as described in Figures 16, 17, and 18, or
the feelers ',, inay be moved laterally by a cam chain worked in the same
manner as the cam chain s, shewn in Figures 16, 17, and 18.
Having thus stated the nature of my Invention, and described several
modes of carrying the same into operation, I wish it to be understood, that I
do not limit myself to the details, nor to the arrangements shewn and
described, as they may be considerably varied and otherwise combined, but
what I do claim is,-
First, the various arrangements of the two series of tappets of different

page_text: heights, and the parts acting in combination therewith, for governing the
position of the shuttle box, the needle board, the pattern cylinders, and other
working parts of the loom, as shown and described.
Secondly, the graduated step levers marked 1, P, and the parts acting in
combination therewith for governing the position of the slittle box, the
needle board, the pattern cylinders, and other working parts of the loom, as
shewn and described.
Thirdly, the application of a toothed or other suitable chain for turning
jacquard cylinders, as shewn and described.
Fourthly, the improved combination of machinery shewn'and 'described in
reference to Figure 8, for turning and reversing the motion of the jacquard
cylinder.
Fifthly, the combination of machinery for varying the position of the
needle board, and locking the same when brought into position, as sliewn and
described.
Sixthly, dividing the needle board in sections and varying the position of
the same, to produce changes in the pattern, as shewn and described.
Seventhly,the application of two or more cylinders to a jacquard engine or
dobby, and the machinery for varying their position for turning them
round, and by which their rotary motion is stopped when required, as shewn
and described.
Eighthly, the combination of machinery shewn and described in reference
to Figures 16, 17, and 18.
And, lastly, the combination of machinery for changing the position of the
feelers to operate on different portions of the pattern chain; as shewn and
described in reference to Figures 19, 20, and 2].
In witness whereof, I, the said James Edward Hyde Andrew, have
hereunto set my hand and seal, this Seventeenth day of October, One
thousand eight hundred and sixty-five.
