Improvements in Moquette Looms.
I, PHILIP ARTHUR NEWTON of The Office for Patents, 6 Bream's Buildings,
Chancery Lane, in the County of London, Patent Agent, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to looms for making tufted fabrics of that class of which the
fabric now known as moquette carpet is an example, this carpet having a body of
warp and weft threads of suitable material, usually jute or hemp, and a face
consisting of rows of tufts of wool inserted into the body during the formation of
the latter, and secured by the weft threals, as distinguished from cut pile fabrics
in which the face is formed by looping the continuous pile material, and trimming
off the outer ends of the loops to form the cut face.
While one feature of the present invention consists in the general construction
and arrangement of a loom by which a row of tufts is inserted to each two shots
of filling in moquette fabrics, the invention includes also certain improvements in
a special class of tufted fabric looms, which forms one of the preferred forms of
looms in which may be embodied this general construction and arrangement, these
improvements being especially valuable in combination with this broad feature of
the invention, although applicable also in looms inserting more than two shots to
each row of tufts.
In tufted fabric looms of one of the common forms, the tuft spools are carried by
a pair of chains, or an equivalent spool carrier, which is advanced step by step to
bring the successive tuft spools into position for use, and these tuft spools are
successively removed from the carrier for the insertion of a row of tufts therefrom,
and returned to the carrier after the row has been inserted. The tuft spools are
commonly carried between the spool carrier and the position of use, by transferring
arms taking and returning the spool at the same point, the movement of the carrier
to advance the next spool into position to be taken by the transferring arms taking
place after the previous spool has been returned to the carrier.
The invention provides an improved tuft spool movement, increasing the capacity
of looms employing a spool carrier, from which the spools are removed for inserting
the tufts by advancing the spool carrier during the movement of the transferring
arms, and between the operations of taking and returning a spool, and changing the
relative positions of the spool carrier support and transferring arms, for returning
the spool and taking the next spool. This change of relative position is secured,

page_text: preferably, by moving the spool carrier support, and when, as is preferable, the
spool carrier consists of a pair of chains in successive links of which the spools are
carried, the chain wheel next the transferring arms is preferably mounted in a
swinging support, which is actuated by suitable means, so as to reciprocate the
lower end of the chains in the line of movement of the chains in proper time to
secure the result desired. By this construction, it is evident that the time required
for the operation of taking and returning the tuft spools, and advancing the spools
for the next row of tufts, is reduced, and thus the possible capacity of the loom
increased.
While either of these general features of the invention may be used without the
other, the improved loom movement being applicable in looms in which the tufts
are inserted in any other manner, and in looms employing removable spools, and
having any other suitable spool movement, and the improved spool movement being
of use in looms in which more than two shots of filling are used to each row of tufts,
it is evident that these two features co-act to secure a very high capacity; and the
invention consists in part in their combination, the insertion of two shots of filling
to each row of tufts reducing largely the time required for the formation of the
body of the fabric, and the special spool movement permitting the attainment of this
high capacity in looms of that special class in which the tuft spools are removed
from the carrier.
The invention includes also certain specific features of construction and com-
binations of parts, all of which will be fully described hereafter, and specifically
pointed out in the claims.
For a full understanding of the invention, a detailed description of a loom and
fabric embodying the same will now be given in connection with the accompanying
drawings, forming a part of this Specification, which shew all the features of
construction forming parts of the invention embodied in their preferred form in a

spool gripped by the transferring arms.
Figures 19 shew the product of this loom, in its preferred form, the fabric
being shewn in plan with the tufts removed, and in longitudinal and cross

The loom shewn is, as to its general character, similar to those in common use for
weaving tufted fabrics, and as the construction and operation of such looms is wel
understood, it will be described only so far as is necessary in connection with the
illustration and description of the invention forming the subject matter of the
present application.

page_text: A is the frame of the loom, in which is mounted, at the rear end, the warp
rolls B, C, from which the warps weighted by weights X are led to the heddles_in
the usual manner. Three heddles are employed, "lettered respectively D, D', D³,
these heddles carrying the warps as usual in such constructions, and the fabric
passes from the weaving mechanism over the breast beam E to the winding-up
roll F.
The warps are arranged in series of four, transversely to the fabric, as usual in
such constructions, & any common or suitable heddle and weft carrier movement may
be used, but the relative operation of these movements differs from that in loomis
previously in use, so as to open and close the warp, and insert the weft as will be
fully described hereafter.
The
In the construction shewn, the heddles D and D¹ carry one each of the binder
warps, and the heddle D carries the dividing warps of each set of four.
heddles D, D, D, are actuated from their respective cams d, d', d, through levers 11,
connecting rods 12, levers 13, and links 14, the cams being carried by a sleeve loose
on the main shaft S, and driven therefrom at one half the speed of the shaft by
gears 15, the main shaft S being driven from driving shaft T by gears 16.
The tuft spools H, having the usual carriages I and tins 17, for inserting the tufts,
are carried by a pair of chains J, forming the spool carrier, as usual in such
constructions, and the tuit spools are transferred from the chains to the warp, for
the insertion of the successive rows of tufts, and returned to the carrier J by
transferring arms K, carried by supports N pivotted to the frame of the machine,
to swing in a vertical plane, and carry the transferring arms between the spool
carrier and warp, the arms K being pivotted to the supports at 41, so as to swing
horizontally toward and from each other, to seize and release the spools. In previous
constructions, the chains J have been stationary from the time that a spool was
taken by the transferring arms, until it was returned to the chains, as the link must
lie in the same position when the spool is taken and returned by the transferring
arms. The present invention provides an improved construction by which the
chains may be advanced to bring the next spool into position to be taken by the
transferring arms while a spool is out of the chains, the correct relative position of
the arms and chains for the return of the spool, being secured by returning the
chains by a movement of such a character as to increase materially the rate of speed
at which the loom may be operated. In the construction shewn, the lower sprocket
wheels 18, of which two are used, instead of being mounted in a fixed part of the
machine, as usual, are mounted in a movable support consisting, in the form shewn,
of a frame G pivotted to swing to and fro in the line of movement of the chains,
and stopped in each direction by adjustable stops 6. This support G is carried by
a rockshaft 19, which is actuated by cam g on shaft S through lever 20, link 21,
and crank arm 22, on shaft 19, at one side of the loom. The chain is advanced to
bring the successive spools into position for the transferring arms by the usual
means, consisting of a ratchet 23 on the shaft of one of the sprocket wheels 18, this
ratchet being advanced by a lever L carrying a spring-pressed pawl 24, and operated
by a cam 1 on the shaft S, through lever 25 and link 26. For the purpose of holding
the chain stationary during the swinging of the support G, so as to prevent the
shifting of the spools, there is preferably used a stop ratchet 27 on the sprocket
wheel shaft, this ratchet being engaged by a stop pawl lever M carrying two pawls
by which the sprocket wheel is held against motion in either direction, this stop pawl
lever M being rocked at the proper time to permit the feeding movement of the
chains by a lever 28 pivotted on the frame, and actuated by a cam m on shaft S,
through lever 29 and link 30. This stop pawl M is shown in Figure 2 in its normal
position, holding the sprocket wheel 18 engaged through ratchet 27, by its pawls,
against movement in either direction, so that the chains are positively held against
movement during the swinging of the support G, and at all times except when this
stop pawl lever is raised, when it is necessary to permit the rotation of the sprocket
wheel 18, for the feeding movement of the chains.
The transferring arms K are swung with the supports N in a vertical plane, to carry
t

page_text: cam ng
the spool between the chains and warp by cams k, at each side of the loom, acting
through levers 31 and links 32; the spool carriages are rocked for the insertion of
the tufts from cams k¹ at each side of the loom through levers 31ª, pivotted on
levers 31, links 33, bell crank levers 34 mounted on a spring pressed shaft, and
links 35; and the transferring arms are rocked in a horizontal plane on the
supports N, to seize the spools by a vertically-sliding bar 36 carrying a
which engages a projection on the side of one of the arms K, this bar 36 being
actuated by a cam 2 on shaft S through lever 37, the two transferring arms being
connected so as to move in opposite directions by a lever 38, and returned to position
to release the spools by a spring 39 connected to the lever, all substantially as in
looms now in common use.
and
The spool carriages are shewn as hung in the chains in a common manner,
the transferring arms are provided with substantially the usual grip for seizing the
carriage and releasing it from the chains, but the construction of the devices
Co-acting with the grip in taking and returning the spool are varied.
These grips preferably seize the spool carriage on each side, so as to hold the
carriage and spool in proper position and prevent its accidental rocking. It is
necessary, therefore, that the spool and spool carriage be held in accurate position
in the chains, to be taken by the transferring arms, and it is desirable also that
means should be provided by which the spool carriage is raised before the grip seizes
the carriage, so as to relieve the pressure on the catch, and is supported and forced
upward into the chains when released by the grips, so as to assure the proper action
of the catch.
In constructions previously in use, fingers or similar devices mounted in fixed
position on the frame have been used for this purpose, but this is not entirely
satisfactory, especially with my improved construction employing the movable chain
support, as for high speed it is desirable that such devices be so constructed as to
aid in the return of one of the spools to the chains, and to act on the next spool
during the shifting of the spool carrier support, so that the grips on the transferring
arms may take the spool at once on the shifting of the support, avoiding the loss of
time which is required to position the carriage, if allowed to swing freely during
the movement of the support, the transferring arms preferably being held stationary
during the movement of the chain support, and the grips being simply moved in to
grip the spool carriage, as the carrier support is shifted.
An improved construction is provided in which the devices co-acting with the
grips in taking and returning a spool to the chains, are carried by the transferring
arms, these devices preferably being so constructed as to allow the support and
chains to move over the transferring arms while the latter are stationary in the upper
position, and co-act with the grip in returning the spool previously taken by the
transferring arms, and to hold the next spool in proper position during the swinging
of the support, so as to be taken at once when the support is shifted. The construction
is shown particularly in Figs. 4, 6, 12, 13, and the detail views Figs. 14 to 17.
The grips shown have the usual three fixed arms 1, in which the spool carriage
rests, and the spring-pressed arms 2, which are pressed against the spool, to hold
the latter against accidental turning, and the spool carriage has the usual catch
spring 3, passing inside the chain link, and released by the grips, when the latter
are pressed inward against it and the arm 4 passing through the link, this arm being
bent outwardly from the catch spring, so as to form a shoulder below the link. It
The
will be understood, however, that the form of these grips may be varied.
improved means co-acting with the grips are as follows:-
A flat spring 40, lying above each transferring arm, is secured in a fixed position
relatively to the sidewise movement of the transferring arms K, and may be carried
by the vertical pivots 41 of the transferring arms, as shown, and secured in a fixed
position thereon by any suitable means. These springs extend to the end of the
transferring arms above the grips, and rest normally on top of the grips, and so as
to be brought just below the shoulders on the spool carriages formed by the arms 4
when the grips are raised by the arms into their upper position to take a spool.

page_text: Each of the springs is provided with a side arm 5, curved over the transferring arms,.
so as to form a cam as shown in Fig. 16, so that the transferring arms raise the-
springs when the arms are rocked outwardly, and the springs are released and
lowered when the arms are rocked inwardly." The operation of the construction.
will be described in connection with the operation of the machine.
The lay O is carried by arms 42 on a rock shaft 43, actuated by cam o on
shaft S, through lever 44 and link 45, and controlled by stop 46. The comb P is
carried by arms 47 pivoted on crank arms 48 on rock shaft 49, the shaft being
spring-pressed in one direction, and actuated in the opposite direction by camp on
shaft S through lever 50, link 51, and crank arm 52, on shaft 49, and the comb is.
raised and lowered by link 53 pivoted thereto, and connected to one arm of the
bell-crank lever 54, returned by spring 55, and actuated against the tension of the
spring by a cam p¹ on shaft S through lever 56 and link 57 connected to the other
arm of the bell crank. The comb P is controlled by an adjustable stop 58. A
pair of horizontally-moving cutting blades are used for severing the tufts, the front
cutting blade Q being carried by arms 59 mounted on rock shaft 60, and actuated
by cam on shaft S, through lever 61, which is pivotted on the frame at 86,.
connected to crank arm 62 on the shaft by link 87, and the other blade Q slides
in guides 63, and is actuated by cams y' on shaft S, through levers 64 and links 65.
at each side of the loom.
It will be understood, however, that these parts, in themselves, form no part of
the present invention, and that other means may be used for trimming off the tufts
and beating up the body of the fabric, such devices being readily varied by those-
skilled in the art.
Any suitable means may be used for inserting the shots of filling, such as any of the-
means now in common use. In the drawings, however, there is shown a common
construction employing a shuttle and needle, which will be found simple and efficient..
In this construction, the needle R, carrying the thread, is actuated from a cam -
on the shaft S through lever 66, link 67, lever 68, and link 69, so that a very
quick movement of the needle is secured. The thread is carried through the fixed
guides 70, and is drawn off the spool by a take-up U, which is rocked to draw off
the thread, and returned to position by a cam disc u on the shaft S, carrying two
cam projections acting through lever 71, link 72, and arm 73, on the sleeve carrying
the take-up U. The thread is caught on the needle side of the loom, so as to be
held until the warp has been shifted and the next shot is being made by a catch c
carried by a bar 84 pivotted at 85 by a slotted pivotal connection, so as to be free-
to slide vertically, and provided with an inclined slot 7, in which engages a bowl
carried by a lever 74, which is actuated by a cam m on shaft S, through lever 75
and link 76, a rod 8 being pivotted to the sliding bar carrying the catch c, and
moving in a bearing in frame A, sufficient friction being provided in this bearing to.
secure the proper up and down movement of the catch, as the bar 84 is moved.
upward and downward by the movement of the bowl on the lever 74 in the inclined
slot 7. At the opposite side of the loom is mounted, in a curved race 77, a
shuttle V, carried by a swinging arm 78, so as to be oscillated for making the
selvage in the usual manner, this arm 78 being carried by a vertical rock shaft 79,.
spring-pressed in one direction, and actuated in the opposite direction against the
tension of the spring, by cam v on shaft S, through lever 80, bell-crank 81, and
link 82, connected to crank arm 83 on the shaft.
The operation of the loom will be understood from a brief description of its.
general features, without a detailed description of the operation of the various
parts, except so far as the latter are new, and in themselves form parts of the
invention, as the operation of the parts of the mechanism in detail is substantially
the same as in looms of this class heretofore in use, and will be clear to those-
skilled in the art.
The operation will be more readily understood after a description of the fabric
in connection with Fig. 19, in which the body of the fabric is shown open, to
separate the threads for the purpose of illustration, it being understood, however,.

page_text: that in practice the filling is beaten up by the lay of the loom, so as to force the
filling and tufts together, and make a solid fabric.
The warps are arranged in sets of four, at short intervals apart across the fabric,
as usual in such constructions, but only two wefts are used to each row of tufts.
Two of each set of four warps form the dividing warps, and lie between the upper
and lower wefts of each pair, and the other two of each set of four warps form the
binding warps, and pass alternately above and below the wefts of each pair, so as
to bind them and the dividing warps together. Of the two shots of filling for
each row of tufts, one shot passes through each row, and forms the bolding shot, and
the other binds the row on the holding shot, and forms the binding shot. In
the construction illustrated, the outside warps of each set of four are used as the
dividing warps, and the inner warps as the binding warps, although it will be
understood that this arrangement is not absolutely essential, and for convenience
of description the warps are numbered in series, the dividing warps being
lettered,, and the binding warps 2, 3, and the holding and binding wefts are
lettered respectively y, y'. The arrow in Fig. 19 shows the direction of movement
of the warp in weaving.
The position in which the parts of the loom are shown in the general views
Figs. 1 to 6, and Fig. 9, is that in which a row of tufts and pair of wefts have been
inserted, the spool has been returned to the carrier, and another spool has just been
taken by the transferring arms K, and is about to be lowered for the insertion of
another row of tufts. In this position of the parts, heddles D and D2, carrying
respectively binding warp 2, and dividing warps ³, x, are raised, and heddle D₁,
carrying binding warp, is lowered, and the lay O is just about to beat up, and the
warps to be shifted into central position. The binding weft y¹ having been beaten
up by the lay, and the warps shifted, the transferring arms K descend with the spool,
and the ends of the tuft material are inserted behind the previous row of tufts and
pair of wefts, and the heddles are then shifted, so as to raise heddle D and binding
warp ², but to lower heddle D2 and dividing warps with heddle D¹ and
binding warp 3. The needle R is then actuated to insert the upper or holding
weft y, the lay beats it up, and the transferring arms are raised slightly to draw
off the tufts, this position of the parts, before the return of the heddles to central
position, being shown in Fig. 7. As the needle is inserted and withdrawn, the
shuttle V passes the selvage thread through the loop of the weft, and the catch c is
raised and lowered in proper time, so as to hold the loop until the warp is again
shifted, each weft in this construction, therefore, being doubled.
The heddles are now shifted into central position, and the lay O being withdrawn,
the comb P is actuated to carry up the ends of the tufts around the holding weft,
as usual in such constructions. The heddles are now shifted again, to open the warp,
heddle D and binding warp a being lowered, and heddles D₁ D², carrying binding
warp and dividing warps, raised, when the needle is again actuated to insert
the binding weft y, and the tufts are cut off by the cutters QQ', this position of
the parts being shown in Fig. 8. The lay O now beats up the binding weft, the
transferring arms are raised to return the spool and take the next spool, and the
cutters return to normal position.
The operation is exactly the same for the next row of tufts, except that the
shifting of the binding warps is reversed, heddle D₁ and binding warp
being raised, and heddle D and binding warp 2 lowered on the first shot, and
heddle D raised and heddle D₁ lowered on the second shot, as will be apparent
from an examination of Fig. 19, showing the fabric, this reversing being preferable
on account of the position of the binding warps after the insertion of the binding wefts.
During the movement of the transferring arms K with the spool, the chains J
were advanced by the pawl arm L and ratchet 23, to bring the next spool into
position to be taken by the transferring arms, the arm M, carrying the stop pawls,
being raised at this time, so as to permit the rotation of the sprocket wheel 18
engaged thereby, and being returned to position as soon as the chains have been
advanced, so as to hold the chains against accidental movement in either direction.

page_text: It is necessary, however, that the link from which the spool was taken by the
transferring arms, be in proper position to receive the spool from the transferring
arins, and to secure this result, the carrier support G is shifted just as the
transferring arms are about to return the spool, so as to return the link to proper
position, and then, immediately upon receipt of the spool, the carrier support,
swung forward again, to bring the next spool into position to be again by the
transferring arms, the movement in either direction of the chain on the sprocket
wheel, during the swinging of the carrier support, being prevented by the stop
pawls on an arm M engaging the stop ratchet 27, and locking against rotation the
sprocket wheel 18 carrying the ratchet 27.
The movement of the spool carrier and swinging support will be clear
from Figs. 6 to 8 and 9 to 13. In Figs. 6 and 9, in which the transferring
arms are just about to take a spool from the chain, the swinging chain support is
in its normal position, and the pawl lever L is in its upper position, ready
to advance the chain. In Figs. 7 and 10, the spool has been withdrawn
from the chains by the transferring arms, and the pawl lever L has been
actuated to advance the chains, so as to bring the next spool into position to be
taken by the transferring arms, the link J, from which the spool carried by the
arms was taken, being now between the two sprocket wheels 18, by which it is held
in horizontal position, ready to receive the spool. In Figs. 8 and 11, the carrier
support G has been rocked rearward, so as to bring the link J for the spool carried
by the transferring arms, over the transferring arms, in proper position to receive
the spool upon the return of the latter.
The action of the grips on the transferring arms and the springs 40 is as follows
As the transferring arms are raised for the return of the spool to the link, the
ends of the springs 40 are brought beneath the shoulders formed by the arms 4 on
the spool carriage, the armis K being then held in their inner positions, gripping
the spool carriage by the cam n engaging the side of one of the arms K. The
spool carriage having been thus brought into position to be taken by the chains, the
arms K are released by the cam n, and the spring 39, acting through lever 38,
throws the arms outward, and the grips release the spool carriage. As the trans-
ferring arms are thus moved outward on their pivots 41, they raise the springs 40
by engagement with the cams 5, and the springs are thus pressed against the
underside of the shoulders formed by the arms 4 on the spool carriages, and act to
press the spool carriages upward into the chains, so as to assure the catching
thereon of catch springs 3, as the spool carriages are released by the grips. This
position of the parts is shown in Fig. 12, the grips having just been moved
outwardly, to release the spool carriage, and the spring 40, being shown in its upper
position, pressing the spool carriage, catches into the chains. The spool carriage
having been returned to the chains, the support G is rocked from the position
shown in Fig. 12 to the position shown in Fig. 13, so as to bring the next spool
into position to be taken by the transferring arms, the springs 40 remaining in
their upper position during this movement, and holding the next spool in position
to be taken by the transferring arms. As soon as the support has been thus moved
into the position shown in Fig. 13, so as to bring the next spool into position to be
taken by the transferring arms, the spool carriage being held in proper central
position, and rocking prevented by the springs 40, and the carriage being raised
thereby, so as to relieve the weight on the catch springs 3, the transferring arms
are rocked inwardly against the tension of spring 39 by the cam n, the catch springs
pressed inwardly by the grips, and the next spool carriage gripped, the springs 40
returning to their lower position as the inward movement of the transferring arms
relieves cams 5. Figs. 14 to 17 show, in detail, the position of the parts corre-
sponding to Fig. 13, and Fig. 18 the position corresponding to Fig. 6, with the
spool carriage gripped. The parts have now been returned to the position shown
in Fig. 6, the next spool carriage having been gripped by the transferring arms,
and the latter being about to descend for the insertion of the next row of tufts.
It will be found that the improved loom is capable of operation at a very high

page_text: rate of speed, the use of the two shots of filling for each row of tufts in the manner
described increasing largely the capacity of the loom, and this very high capacity being
made attainable by the use of the movable support for the spool carrier. As above
stated, however, these two features form in themselves parts of the invention, inde-
pendently of their combination, and either may be used in looms not employing the.
other. It is obvious that the improved construction of devices co-acting with the
grips in taking and returning a spool, may be used without the movable support, but
it is of especial value in combination therewith, as pointed out above.
It will be understood that the construction of the other parts of the loom
co-acting with the features especially embodying the invention, may be varied
widely, and that the form shown has been selected only for the purpose of illustra-
tion, and as a convenient construction of high capacity loom. It will be understood,
also, that the invention is not to be limited to the special form or arrangement of
the spool movement shown as embodying this part of the invention, but that this
construction may be varied widely without departing therefrom. Thus, while it is
preferable that the spool carrier support should be shifted relatively to the
transferring arms, as this will be found the simplest and most efficient construction,
it will be understood that the relative positions of these two parts may be varied,
for the return of the spool, in any other suitable manner.
It will be understood that the term "moquette looms" means, and is intended to
cover, all looms for weaving carpets or other fabrics having rows of separate and inde-
pendent tufts inserted in the body, but does not include looms for weaving pile fabrics
in which the face is formed of a series of loops in continuous strands of pile material,
nor that similar class of fabrics known as double pile fabrics; nor that class of fabrics
in which the face is formed by inserting a weft strand carrying a row of tufts attached
thereto.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
from abroad, I declare that what 1 claim is :-
1. The combination with the warp heddles, and means for inserting the tufts, of
a weft carrier and means for actuating said heddles and weft carrier, to insert two
shots of filling to each row of tufts, substantially as described.
2. The combination with dividing warp and binding warp heddles, and means for
actuating said heddles to open the warp in the manner described, of means for
inserting the tufts, a weft carrier, and means for actuating the weft carrier to insert
a tuft-holding and a tuft-binding shot of filling to each row of tufts, substantially
as described.
3. The combination with a tuft spool carrier, carrier support, and means for
transferring the spools for the insertion of the tufts, of means for advancing the
carrier and spools therein while a spool is out of the carrier, and means for
varying the relative positions of the spool carrier support, and transferring
means, for the return of the spool by the said transferring means, substantially as
described.
4. The combination with the tuft spool carrier, carrier support, and means for
