Improvements in Change-box Motions of Power Looms for Weaving
Textile Fabrics.
I, BENJAMIN SMITH of 6-11 Forbes Place, Paisley in the County of
Renfrew, Scotland, Manufacturer of Textile Goods, do hereby declare the nature
of this invention to be as follows:-
It has hitherto been customary to effect the operation of the motion or gear for
changing the shuttle boxes of power looms when a change of color or pattern of
the fabric being woven is required, either by the use of a perforated barrel, known
as the "barrel motion," or by the use of chains known as the "chain motion."
The former of these, namely the barrel motion, is only applied to looms, used
for weaving single cloth fabrics, the said barrel motion being impracticable or
unsuitabe for weaving fabrics such as those known as "reversible' or "double
cloth fabrics," where a single pick or thread of weft is used in a place in the
pattern which can be woven only upon a loom known as a "pick" and " pick"
loom, for the reason (in the case of double cloth) that the threads of each face
must be woven alternately. It has therefore been customary hitherto, when
weaving reversible or double cloth (as the best known method), to employ the
before mentioned chain motion, in which one link was required for each and every
pick or thread of the weft in the pattern and as there are as many as 950 such
picks or threads of the wefts for certain patterns, it has required chains having a
like number of links for operating the said picks, but this method except where the
patterns are very small entails great expense, partly in the first cost of the chain,
partly in the time wasted by the operator in adjusting, fixing, and arranging the said
chains, and partly by reason of two such chains being required for producing
fabrics of certain patterns. It is also well known that the said chain motion is
impracticable or unsuitable for the weaving of such fabrics when the patterns are
large for which the before mentioned barrel is adaptable.
My invention consists of a method and means of combining the said barrel and
chain motion, upon one and the same loom, in such a manner, that (within
reasonable limits) any kind of fabric, of any pattern, or any number of colors,
may be woven upon any kind of loom, and I attain this by the employment of
suitable levers, rods, cords, chains or any desired combination of these or their
equivalents, which may be operated by and from the said barrel motion, so that
there may affect or act upon the said chain motion, or these may be operated by
and from the said chain motion, so as to affect or act upon the said barrel motion,
or be so combined, that both motions may act alternately or otherwise upon each
other, as may be most convenient or suited to the weaving to be done.
By this combined arrangement of the two said motions (which may be applied
to any kind of power loom, either ordinary or that known as a pick and pick loom)
1 find in practice, that I am enabled to weave a fabric of any texture, having any
number of picks or threads of weft in the complete pattern, which may have as
many as 13 changes of the checking or colors therein, by the employment of a
chain having only 26 links, as any number of picks can be wrought by the use of
one or two links for each change in the checking of the pattern, instead of having
one link for each pick or thread of weft as hitherto, thus effecting a great saving
in the working of the loom, by reason of the employment of a lesser number of

page_text: parts to deteriorate by wear and tear, and the time saved to the operator in the
adjustment and manipulation of the same.

Improvements in Change-box Motions of Power Looms for Weaving
Textile Fabrics.
1, BENJAMIN SMITH of Forbes Place, Paisley, in the County of Renfrewshire,
Manufacturer, do hereby declare the nature of my invention and in what manner
the same is to be performed to be particularly described and ascertained in and hy
the following statements in writing, that is to say :-
It has hitherto been customary to effect the operation of the motion or gear for
changing the shuttle boxes of power loons, when a change of color or pattern of
the fabric being woven were required, either by the use of a perforated barrel
known as the "barrel motion "
or by the use of chains known as the "chain
motion."
The said barrel motion has hitherto been applied only in connection with looms
used for weaving single cloth fabrics, the said barrel motion being unsuited for
weaving fabrics such as those known as "reversible" or "double cloth fabrics" or
any fabric where a single pick or thread of weft is used in a place in the pattern,
which could be woven only upon a loom known as a "pick and pick loom" for the
reason (in the case of double cloth) that the threads of each face must be woven
alternately. It has therefore been customary hitherto when weaving such
reversible or double cloth (as the best known method) to employ the before
mentioned chain motion, in which one link was required for each and every pick or
thread of the weft in the pattern, and as there are in some patterns as many as
950 such picks or threads of the wefts, it has required chains having a like number
of links for operating the said picks, and this (except where the patterns were
very small) entailed great expense, not only in the first cost of the chain, but in the
time wasted by the operator in adjusting, fixing, and arranging the same. It is
also well known that the said chain motion is impracticable or unsuitable for the
weaving of fabrics when the patterns are large on account of the length of the
chain, cost, manipulation and motive power necessary to operate it.
My invention is designed or intended to dispense with this immense length and
weight of chain, and the absolute need of the chain motion for certain fabrics, or
the absolute need of the barrel motion, for certain others, and my invention
consists of a method and means of combining and using both the said motions upon
one and the same loom in such a manner, that (within reasonablo limits) any kind
of fabric of any pattern or any number of colours may be woven upon any kind of
loom of this type either ordinary or that known as pick and pick, and I attain this
by the employment of suitable levers, rods, clutches, or the like so combined and
connected as to be operated by and from the said barrel motion so as to act upon
the said chain motion in such a manner that only a very small length of chain is
needed, whatever may be the number of picks or threads of wefts in the patterns,
and I find in practice that by the said combined motion I am enabled to weave a
fabric of any texture, which may have as many as 13 or more changes of the
checking or colour therein by the employment of a chain having only 26 links or
thereabouts, as according to my invention, almost any number of picks can be
wrought by the use and repeated use of one or two links for each change or check

page_text: of the pattern, instead of having one link for each pick or thread of the weft as
hitherto, thus effecting a material saving in the cost of labour and in the initial cost
of the loom and the wear and tear of the same. The shuttle box chain is thus
operated through suitable mechanism from the pattern barrel and changes the
shuttle boxes at each change of pattern, ordinary mechanism being used between
shuttle box chain and shuttle boxes.
In order that my invention and the manner in which I attach it to, and manipulate
it in connection with existing looms may be fully understood, I have hereunto
appended 6 sheets of drawings in which I have chosen to illustrate its application
to an ordinary "Dobcross" fast power loom, but I wish it understood (and it will
be easily understood by all persons versed in the manipulation of looms of this
type) that the same is applicable for use in connection with almost every kind of
loom of this class.

Figure 17 is an end view corresponding to Figure 16 and Figure 18 a plan view

In Figures 1 and 2 of the accompanying drawings A is the frame of the loom
BCD and E are revolving shafts, the latter of which gives motion to a set of
mitre wheels F which actuates gearing F F and F³, and rotates shaft, for
operating the twilling chain G, all of which are common to such a loom, and form
no part of, except in combination with my invention.
For the purposes of my invention I mount upon a frame H (located in a suitable
position near the loom A) a barrel I, having upon its periphery in spiral form
equidistant perforations or holes J, and carrying upon one end a spur wheel K and
upon its opposite end a ratchet wheel K'. The frame H also carries a preferably
left handed worm or threaded shaft L, upon one end of which is mounted a pinion L'
in gear with the spur wheel K, and upon its opposite end a ratchet wheel M. Upon
the spindle of the barrel I is pivotally mounted a lever N the arm of which extends
horizontally, and rests, by the tension of a spring a, upon a cain O, mounted upon
the extreme or extended end of the power shaft B. Upon the lever N is pivoted
at b, a pawl P, in such a position that one end may, when required, engage with
the ratchet wheel M, while its opposite end carries a pin c which extends
horizontally between the forks d and d¹ of a bifurcated plate or pawl e, also
pivotally mounted upon the lever N in such a manner, that the fork d' may, when
required, engage with the ratchet wheel K. The pawl P also carries a projecting
pin e from which depends an arme, the lower end of which is in pivotal connection
with a bell crank lever f, mounted upon the bearing end of a square or polygonal
sectioned oscillating rod Q, borne by the frame H, the tension of a spring "¹
operating upon the bell crank to keep this in the position shown by Figure 5.
The worm L carries an internally threaded boss R of a double armed fever, one

page_text: arm of which g depends and is curved parallel or thereabouts with the radius of
the periphery of the barrel I, and passes between the arms g' and g² of a bifurcated
block g which slides upon the rod Q, and is carried along by arm g as it moves
along the screw shaft L.
The opposite arm; of the boss R extends horizontally over the barrel I, and has
upon its under surface a projection, while its free end passes through a slot in a
horizontal plate S, arranged to slide vertically in upright standards S₁ and S.
From the plate S extends a rod k pivotally connected to one end of a horizontal
lever k, fulcrumed upon a standard, the opposite end of ¹ being pivotally
connected to the lower end of a vertical rod / connected to one arm of a bell crank
lever m fulcrumed at m¹ to the loom frame A, the opposite arm of m being pivotally
connected to a rod n, the ends of which are pivotally connected to a pair of clutch
levers n, n forming part of a clutch mechanism, the motion of which needs a
separate explanation, and is more graphically illustrated by the enlarged views
Figures 10 and 11, although shown in position upon the loom in Figures 1 and 2.
By the means of a suitable bracket, or its equivalent, fixed upon the frame A,
I mount a rectangular frame T, which carries in bearings p and p' a revolving
spindle T, upon one end of which is fixed a mitre wheel T, which gears with a
similar wheel T³ mounted upon an approximately upright shaft U, borne in suitable
brackets fixed to the frame A or otherwise as may be most convenient, upon the
lower end of which is a like mitre wheel U in gear with a mitre wheel U³. Upon
the same shaft is a spur wheel D, which by means of the intermediate spur wheel E,
is connected with shaft C of the loom, so that spindle T' is continually revolving.
Upon the said spindle is fixed a pair of blocks and reach provided with a hole
through which pass freely pins connected to and projecting from a pair of
clutches and, mounted loosely upon the spindle T but always revolving
therewith, by reason of their connection with the fixed blocks rr, and with the
clutches and are connected the levers n' and n³, preferably with their ends
pivotted upon the frame T, so that the rod n connects them centrally of their
length or thereabouts, but I may find it convenient to extend the length of these as
shown by the dotted lines, so that the rod n may be connected to the ends of same
as shown.
Referring again to Figure I, I have previously mentioned that the shaft F* upon
the loom carries the usual loug chain G, which hitherto has been employed for
operating the shuttle boxes in the manner stated. In the present method of
carrying my invention into effect I do not use this shaft except to form a bearing
end for a shaft V, upon which are mounted one, or may be two, short lengths
of chain G', the backward and forward movements of which, as hereinafter
explained, cause the links of the chain used to operate the shuttle boxes in the
same way as the hitherto continuous travel of the chain G. Upon the free end
of the shaft V I fix a star wheel W (reference being again made to Figures 10
and 11) in which are preferably but not imperatively, six incisions or apertures s,
with which engage one or the other of the pins and rotate W, one sixth of a
revolution in one direction or the other, as hereinafter explained.
The perforations or holes J in the barrel are for the reception of wefting pegs,
of which there are many forms in general use, but I do not claim any form of
wefting pegs for the purposes of my invention, but employ any forin of peg the
head of which is of such a height as to collide with the projection, and operate
the lever and slide S and its connections, or the curled projections h and h¹ of the
block 9 upon the rod Q as hereinafter explained, an example of which said pegs is
shown by the enlarged views Figures 8 and 9 and hereinafter referred to by the
letters and t¹.
The shuttle box chain or chains G¹ is or are controlled entirely by the manner
in which the barrel I is pegged, and it is assumed that the first link of the chain
in use is put into position by the operator at the starting of the loom, in the
manner well understood. The manner of operation is as follows.
The cam O raises the lever N once every revolution of the craak shaft B.

page_text: Every time the lever N is raised the fork d' of the bifurcated plate e engages
with the ratchet wheel K¹ and pushes the barrel I round in the direction of the
arrow Figure 1 a distance equal to one tooth of K, which is also equal to the
distance from one hole J to the next, such movement of the barrel also causing
the spur wheel K to impart motion to the pinion wheel L and the worm
upon which it is fixed, and the rotation of L would cause the boss R thereon
to be carried from one end of the worm to the other, which would also cause
the lever arm j to slide from one end to the other of the slot in the plate S, while
the projection of the arm i would always be over and resting upon the spirally
disposed holes J in barrel I, and the lever arm g would cause the block g and its
curled arms and ' to slide from one end to the other of the square or polygonal
sectioned rod Q. There is no fixed rule as to how the barrel shall be pegged as
these must be placed in such order and in such quantities as will govern the
checking of the pattern and the fabric to be woven, which in some cases may
necessitate that the holes J be pegged alternately, or peg two and miss one, or
vice versa, or several holes may be pegged or missed consecutively, an example of
which is shown in Figure 4, in which three holes are pegged consecutively and one
missed in regular order. In whatever order the pegs t may be placed in the barrel,
each of these as they come round would collide with the projection j³, and raise the
lever arm and this raising the slotted plate S and its rod k would raise that end
of the lever k³, and consequently lowers its opposite end, thus imparting a downward
pull upon the rod 1, and the lower arm of the bell crank lever m, the upper arm of
which operates the rod n and consequently the clutch levers n' and ², thereby
removing the clutch from the block and placing the clutch close up to the
block with its pinprojecting through r, and this engaging with the nearest
recess in the star wheel W would rotate this, the shaft V, and chain wheel and
chain G' one sixth of a revolution, thus bringing the second link of the chain into
use to operate the shuttle box in the usual way, but when the weft peg t has passed
the projection and this is again resting upon the barrel I this action of the clutch
is reversed and consequently the star wheel W shaft V and shuttle box chain G'
are turned back by reason of the pin of the clutch operating upon
the opposite recess of the wheel W, thus bringing the first link of the chain
again into use for operating the shuttle box, thereby using the first and second
links only of the chain G alternately, and this operation would be repeated
for every peg t in the barrel, these being placed in such order and number as
necessary till all the colors working were completed, at the end of which, or the
completion of half the pattern it becomes necessary to reverse the motion of the
barrel. To effect this the operator would place one or more of the longer pegs t¹
(Figure 8) in such a position of the holes in the barrel, that this or these would
collide at the right moment with the curled projection of the block g³ as shown
in Figure 3, which would tilt the block g³ as shown in Figure 7, thereby partly
rotating the square or polygonal sectioned rod Q, and deflecting the bell crank
lever f, which, imparting a downward pull upon the link would lower the point
of the pawl P, causing this to engage with the ratchet wheel M, and by the
opposite end of P rising, its stud c would lift the bifurcated pawl e so that its lower
fork d would be lifted out of contact with the ratchet wheel K', so that at the
next rise of the lever N the point of the pawl P would impart motion to the
ratchet wheel M in the direction of the arrow Figure 5, and consequently
the worm Land pinion L' thereon, the latter imparting motion to the spur wheel K
and barrel I in a direction opposite to that shown by the arrow in Figure 1, and
the rotation of the worm in this direction would cause the boss R to travel back
thereon and the projection; upon to collide with the pegs t in reverse order, and
so operate the shuttle box chain G' as before described. In like manner when the
barrel I is again required to move forward a peg t¹ is placed in such position as to
collide with the curled arm which, tilting the rod Q in the manner shown by
Figure 6, would cause the bell crank to raise the pawl P from the ratchet wheel M
and lower the fork d', so that this may again engage with and operate the ratchet

page_text: wheel K' as before. When weaving single cloth, with not less than two picks at
any place in the pattern, the picking chain is wrought independent of the shuttle
hox chain, and only one clutch is needed. The barrel is for this class of fabric
pegged one hole for each color, or change in checking, at the point when it is
needing to change the color, so that one hole only is pegged for each change of
color and the clutch is put out of gear and remains so except when there is a peg
placed in the barrel, which, coming in contact with projection of lever j, as it
revolves, the clutch is put in gear, and the pin of this falling into a notchs of
star wheel W, a fresh link is brought into operation in the manner already
described. Therefore, if there are 20 changes in the pattern, according to my
invention only 20 links of the shuttle box chain G would be used, and only
20 holes in the barrel need pegging, or only half that number of pegs if the pattern
turns in the centre and the direction of motion of the barrel I can be reversed as
previously described. The picking in this fabric is controlled by using one of the
levers of the treading motion.
When reversible fabric (or that known as pick and pick) is being woven, the
barrel I would be pegged alternately for the requisite number of holes, that is to
say, if the fabric wanted 100 threads of scarlet upon one side, and 100 threads of
black upon the other 200 holes of the barrel I would be pegged alternately, con-
sequently the to and fro motion of the clutches, and the shuttle box chain, would
be alternate, and when it is wanted to alter the color or checking, the barrel is
pegged three holes consecutively or three holes left empty, so that two new links
of shuttle box chain may be brought into operation, and afterwards the alternate
pegging continued until the next change in the pattern, and according to such
pegging one or the other of the clutches or are brought into use, while the
other remains idle pro tem.
If single cloth, with single or odd picks is being woven the pegging is after the
same order as above, but where the single pick comes in, 4 holes are pegged con-
secutively or 4 left empty, and in both these fabrics the picking chain and the
shuttle box chain may be connected.
In Figures 12, 13, 14, and 15 I illustrate an alternative motion, which has for its
object the connecting of the Jacquard pick and shuttle box motion with the barrel I,
in such a way that, when the operator has to turn back so as to take out part of
that already woven on account of mistake in color, holes in cloth, wrong treading
or other causes, the whole of these parts are moved back together. The turning
back is done by the use of the band wheel X, Fig. 1. In the motion already
described when such turning back is necessary the barrel 1 can be turned back by
hand separately, the number of pegs or holes corresponding to the number of picks
or threads to be removed or rectified. The shuttle box chain would not require to
be moved unless when more than one color of weſt was taken out which can also
be done by hand.
Referring to Figure 10 in this motion I dispense with the bevel gear T2 and T
and the mechanism actuating the same, and mount upon the opposite end of the
clutch shaft Ta mitre wheel Z which gears with a like-wheel Z' keyed upon a
shaft Z which is carried in suitable bearings across the face of the loom and has
mounted upon its opposite end a spur wheel Z3 which gears with the spur wheel F³
upon the chain shaft F of the loom (Figure 1) and upon the extreme end of the
Baid shaft F is keyed a mitre wheel Y (Figure 1).
Referring to Figures 12, 13, 14, and 15 upon the frame H of the barrel I
I mount an auxiliary frame H', which carries upon its upper surface in suitable
bearings pl pa spindle v upon which are loosely mounted clutches »' and v³ each
provided with a pin passing through holes in blocks w w' fixed upon the spindle v
the said clutches being operated by clutch arms w³ and w³ pivotted upon H', and
connected by a rod y operated by a bell crank lever y' (Figure 15) pivotted upon
the frame H', or in some other convenient position, and in pivotal connection with
the upper, and may be the extended end of the link e. Upon one end of the
spindle vis keyed a mitre wheel y³ which gears with a like wheely upon a spindle z

page_text: .
carried in a bracket such as =' fixed upon the frame H³, the opposite end of the
spindle z having keyed thereto a mitre wheel which gears with the mitre wheel Y
upon the shaft F (Figure 1) previously mentioned.
The frame H also carries in suitable brackets a short spinille upon one
end of which is mounted a star wheel W having recesses s', and upon the same
spindle is keyed a pinion wheel W which gears with, a spur wheel a³ in gear
with the spur wheel K upon the barrel I.
According to this arrangement I employ the gear F F F and F actuated by
the shaft E, upon the frame A, which by the means of the shaft 'Z' and hevel
wheels Z and Z serves to impart continual motion to the spindle T' (Figure 10)
otherwise as shown in Figures 12, 13, and 14 by means of the bevel wheel Y
upon F, motion is given to the bevel wheel, the shaft z, mitre wheels y³ and y
and the spindle and blocks to and to thereon. As my invention is capable of
being applied to looms of various constructions, different arrangements of gearing
may be used to impart motion to the spindles T¹ or without departing from the
essential features of my invention. The clutch when closed up to block o
would extend its pin so that by the rotation of the clutch spindle this would
engage with the apertures s' in the star wheel to and impart motion in one direction
to this and its spindle, the pinion W upon which would impart motion to the
spur wheel and the spur wheel K, and consequently the barrel I, the operations
of which would be the same as that previously described, that is to say, the insertion
of suitably disposed pegs would operate the lever j, rod k, lever k', rod I the
clutch mechanism (Figure 10) and the star wheel W, and shuttle box chain G'.
At the end of the pattern or wefting pegs t in I, the insertion of a reversing
peg would operate the shaft Q in the manner previously described, and this
operating the bell crank leverf would pull down the link e and consequently
operate the bell crank lever y¹ (Figure 15) and the rod y and this changing the
position of the clutches and v³ would place the pin of the former in a position
to engage with the star wheel W' and so change the direction of rotation of the
barrel 1.
By this motion the benefit is obtained, that the treading, picking, and shuttle
box motion are so connected with the barrel I, that when it is necessary to reverse,
all these motions are turned back together in the same order as they are working,
so that the operator cannot make the mistake of turning back the treading and
omit to move the shuttle box chain or barrel, or rice versa. As shown in
Figures 16 to 18 behind the shuttle box chain wheel Us on same shaft a steadying
wheel W' is mounted, having the same number of notches s' as the star wheel W
and into one of these the V shaped part W of a lever W is drawn by a spring C¹.
The shuttle box chain wheel U³ is by this means kept in its place from sliding
under shuttle box levers 138 and B₁ when in use. When it is wanted to move the
shuttle box chain wheel U³ the lever Wis lifted out of the notch by a kicker ¿ª
on crank shaft coming in contact as it revolves with lever d³, lever W being
connected with lever by rod Z. This motion may be "larly applied to the
barrel, the object being to prevent the chain wheel from moving out of its proper
position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
