We, GEORGE CROMPTON, loom builder and HORACE WYMAN, loom builder both of
Worcester, Massachusetts, United States of America do hereby declare the nature of
our invention to be as follows :-
This invention relatos to looms of the class adapted for the production of tufted
fabrics, such for instance as Moquette carpets, the object of the invention being to
improve and simplify the means for controlling the tuft yarns in order that the same
may be taken directly from independent spools or bobbins, one for each yarn, thus
obviating the beaming of yarns of different colors on separate warp beams, one for
each transverse row of tufts; and also dispense with the chains and moving devices
therefor, as heretofore usually employed.
In accordance with this invention the tuft yarns are taken from separate spools as
in the weaving of Wilton and Brussels carpets, and are led through suitable eyes into
needles or carriers held by carriages arranged a short distance above the
warp threads
between the breast beam and the lay and made movable in the direction of the length
of the warp threads, or through guides or passages made in the said carriages, the
said carriages being arranged side by side across the warp one for each longitudinal
row of tufts, the said needles, guides or carriers of the carriages, through which the
tuft yarns are drawn, being arranged one behind the other in the direction of the
length of the warp threads, the ends of the tuft yarns depending below them in
position to be seized and taken down through between the warp threads and be
inanipulated to form tufts, a Jacquard or pattern surface acting to move the carriages
at different times for different distances to thus enable any needle guide or carrier of
any carriage to be placed in position to have its tuft yarns taken for the production
of a tuft.
The yarns coming from the spools and entering the needles guides or carriers of
each carriage and of different colors, and by moving the carriages, the needle guide or
carrier having a yarn of the desired color may be brought into position to be taken by
the nippers or other usual device commonly employed in this class of loom to be taken
between the warp and be made into a staple-like tuft.

page_text: This invention therefore consists, essentially, in a series of carriages arranged side
by side, a Jacquard to move them varying distances in the direction of the length of
the warp threads, and a series of tuft yarn carriers, guides or needles arranged in the
said carriages one behind the other in the direction of the length of the warp, and
supplied with tuft yarns of different colors from special spools, combined with cutting
mechanism to cut the tuft yarns, and with nippers to seize the ends of the tuft yarns
and carry and place the tufts between the warps after they are cut into tuft forming
lengths.
Also in a loom for the production of tufted carpets, a series of carriages arranged
side by side across the loom above the warp threads and movable in the direction of
the warp threads and containing a series of tuft yarn needles, guides or carriers
arranged therein one behind the other in the direction of the length of the warp
threads, the guides or carriers of each carriage being supplied with yarns of different
color taken from separate spools according to the colors desired in any one longitudinal
row of tufts, combined with a Jacquard or pattern surface and intermediate devices
actuated thereby whereby the carriages are moved for different distances preparatory
to making each row of tufts to bring any desired tuft yarn needle, guide or carrier of
each carriage into the proper line to have its tuft yarn taken by any usual device and
carried through between the warp threads and be cut to form a staple-like tuft.
This invention is intended as an improvement upon the loom described in our
application for British Patent filed of even date herewith, the loom herein described
being especially designed to make carpets known as Moquette, or carpets wherein
tufts are locked or bent about the weft.
This invention is also intended as an improvement upon the class of loom shown in
application for British Patent filed November 10, 1885 and numbered 13,684.
In a loom embodying our invention the weft or filling will be inserted by a needle
like invention such as commonly employed in looms of this class, the loop of weft
thread at the opposite side of the shod from which it entered, being locked by the
throad carried by a small shuttle.

Improvements in Looms for the Manufacture of Tufted Fabrics.
We, MARY C. CROMPTON, of Worcester, Massachusetts, United States, administratrix
of the estate of the late George Crompton same place loom builder, and HORACE
WYMAN loom builder, same place, do hereby declare the nature of our 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 of the class adapted for the production of tufted
fabrics, such for instance as Moquette carpets, the object of the invention being to
improve and simplify the means for controlling the tuft yarns in order that the same
may be taken directly from independent spools or bobbins, one for each yarn, thus
obviating the beaming of yarns of different colors on separate warp beams, one for each
transverse row of tufts; and also dispense with the chains and moving devices therefore,
as heretofore usually employed.
In accordance with this invention the tuft yarns are taken from separate spools as
in the weaving of Wilton and Brussels carpets, and are let through suitable eyes into
needles or carriers held by carriages arranged a short distance above the warp threads
between the breast-beam and the lay and made movable in the direction of the length
of the warp threads, or through guides or passages made in the said carriages, the said
carriages being arranged side by side across the warp one for each longitudinal row
of tufts, the said needles, guides or carriers of the carriages, through which the tuft
yarns are drawn, being arranged one behind the other in the direction of the length of
warp threads, the ends of the tuft yarns depending below them in position to be
seized and taken down through between the warp threads and be manipulated to form
tufts, a jacquard or pattern surface acting to move the carriages at different times for
different distances to thus enable any needle guide or carrier of any carriage to be
placed in position to have its tuft yarns taken for the production of a tuft.
the
The yarns coming from the spools and entering the needles guides or carriers of each
carriage and of different colors, and by moving the carriages, the needle guide or
carrier having a yarn of the desired color may be brought into position to be taken by
the nippers or other usual device commonly employed in this class of loom to be taken
between the warp and be made into a staple-like tuft.
This invention therefore consists, essentially, in a series of carriages arranged side by
side, a jacquard to move them varying distances in the direction of the length of the
warp threads, and a series of tuft yarn carriers, guides or needles arranged in the said
carriages one behind the other in the direction of the length of the warp, and supplied
with tuft yarns of different colors from special spools, combined with cutting mechanism
to cut the tuft yarns, and with nippers to seize the ends of tuft yarns and carry and
place the tufts between the warps after they are cut into tuft forming lengths.
Also in a loom for the production of tufted carpets, a series of carriages arranged
side by side across the loom above the warp threads and movable in the direction of
the warp threads and containing a series of tuft yarn needles, guides or carriers

page_text: arranged therein one behind the other in the direction of the length of the warp thread
the guides or carriers of each carriage being supplied with yarns of different color
taken from separate spools according to the colors desired in any one longitudinal row
of tufts, combined with a jacquard or pattern surface and intermediate devices actuated
thereby whereby the carriages are moved for different distances preparatory to making
cach row of tufts to bring any desired tuft yarn needle, guide or carrier of cach
carriage into the proper line to have its tuft yarn taken by any usual device and carried
through between the warp threads and be cut to form a staple-like tuft.
This invention is intended as an improvement upon the loom described in our
application for British Patent filed of even date herewith, the loom herein described
being especially designed to make carpets known as Moquette, or carpets wherein tufts
are locked or bent about the weft.
This invention is also intended as an improvement upon the class of loom shown
in application for British Patent filed November 10, 1885 and numbered 13,684.
In a loom embodying our invention the weft or filling will be inserted by a needle
like invention such as commonly employed in looms of this class, the loop of weft
thread at the opposite side of the shed from which it entered, being locked by the thread
carried by a small shuttle.
A weft or filling needle of suitable construction is described in our said application
and in the application No. 13684 referred to.

Desiring to dispense-with-long chains ordinarily used in looms for making tufted
carpets, as for instance in British Patents No. 235 for the year 1877, and No. 4150
for the year 1880, and as provided for in the application No. 13,684 referred
to, and with the series of small beams, carried thereby, one for each transverse row of
tufts to be made in the production of the pattern in the fabric, each of the said beams
having tuft yarns wound thereon in the order of the colors to appear in some one trans-
verse row of tufts, we have provided the loom with a series of carriages E placed side
by side across the loom and supported thereon just above the warp threads, the said
carriages as herein shown resting in grooves of rests or bars 109, and being free to be
slid or moved forward and backward with relation to the lay and breast-beam and in
the direction of the length of the warp, by the action of a suitable jacquard or pattern

page_text: surface to be described, the cards or surfaces of which through one or the other of a
series of projections 2, 3, 4, 5, 6, 6* extended from the end of each carriage as shown
best in Figs. 1 and 3.
Each carriage has a stop 7 which is normally kept pressed against one of the bars
or rests 109 by a spring 8 connected at one end with a pin 9 attached to the carriage E,
and at its other end with a rod 10 held at each end by a bracket as at 55 secured to
the frame 12 which supports the shaft 14 of the hollow hexagonal barrel 13, preferably
composed of metal plates joined to head-pieces the latter receiving the shaft. 14.
Each of the plates composing the barrel 13, is provided as herein shown with six
longitudinal rows of holes to correspond with the six projections 2 to 6× inclusive of
each carriage, there being as many holes in each longitudinal row of holes as there are
carriages E in the series of carriages from side to side of the loom, there being as many
carriages as there are tufts in each transverse row of tufts.
But one end of the shaft 14 is shown in the drawing, and in practice, the other end
thereof will be supported in the same manner.
The shaft 14 shown in the drawing is
provided with a bevel gear 16 and with a wheel 17 having pins 18, which are engaged
by a pawl 19 pivoted at 21 on a standard 20 fig. 1 attached to the loom frame near
the breast beain 22.
The bevel-gear 16 engages a bevel gear 23 on the upright shaft 24 held in bearings
attached to frame 12. The upper end of the shaft 24 has a bevel gear 25 which
engages a bevel gear 26 on a shaft 27, having upon it a barrel 28. The shaft 27 has
a toothed wheel 29* which engages a toothed wheel 30 on a shaft 31 provided with a
third barrel 32, and below this barrel is a suitable cradle 33 to support the chain of
pattern cards 29 in usual manner, the said barrels being operated to move the chain
of pattern cards intermittingly.
The pattern-cards 29 connected together in the proper order and constituting the
pattern surface, are each provided with holes some of which coincide with those of the
barrel 13, but each pattern card serves to close one or more of the holes of each vertical
row of holes in the barrel, the particular hole which is so closed depending upon the
exigencies of the pattern in the fabric being woven.
Figure 2 shows a portion of one of the pattern cards punched in design.
The frame 12 is vibrated or swung backward and forward at regular intervals by
links 35, attached in practice to the shaft 14 of the barrel 13, and to the elbow lever 36,
mounted loosely on a shaft G³, the said elbow levers being connected each by a link 38
with a lever 39 pivoted at 40 and acted upon by a cam 44 there being a like link, lever
and cam near cach side of the loom.
As the barrel is swung outward by the devices described, the hooked pawl 19 in
engagement with a pin 18 effects the rotation of the said barrel, bringing a new card
in position with relation to the projections 2, 3, 4, 5, 6, 6*.
The carriages shown in Figs. 1, 3 and 5 are provided at one side with pins c, leaving
spaces between them which constitute pockets or grooves for the reception of a series
of carriers or needles c to c³ inclusive which form guides for the tuft yarns. These
pockets receive the tuft yarn-carriers or needles c to c³ respectively arranged in a row
one back of the other as shown best in Fig. 1.
Fig. 16 shows a modified form of carriage made as a bar provided with a series of
holes made through it from edge to edge, each hole constituting a guide for a tuft
yarn, the edge of the carriage from which the tuft yarns emerge being preferably made
to present a series of hollow cones.
The points of the tuft carriers or needles employed in Figs. 1, 3, 5 and 6, are shown
as flattened tubes having eyes or openings at their lower ends for the delivery of the
tuft yarns, and above their ends the carriers or needles are shown as composed of wire
having at their upper ends, eyes 40, by which they are suspended upon rods or wires 41,
each carrier or needle having an intermediate guide eye 15, through which is led the
tuft yarn t, each tuft yarn entering the eye of each needle coming in practice from an
independent spool or cop containing but one yarn, the said spools or cops being
supported upon a frame arranged at the rear of the loom frame, as are the spools or
cops in looms commonly used in the production of Brussels and Wilton-carpets and as

page_text: shown and described in another application No. 7313 for British Patent filed by us
concurrently herewith.
The tuft yarn carriers, guides or needles which receive the tuft yarns through
them are of such length as to hold the said yarns frictionally, so that when the yarns
outside the carriers, guides or needles, are cut off, the yarns within the said carriers,
guides, or needles will not slip back.
After the formation of each row of tufts, the barrel 13 and pattern cards are moved
to the left, viewing Figure 1 by the spring 42 fig. 1 connected with the lever 39
before described, and the barrel is turned one step bringing a new card in working
position.
The projections 2 to 6* are of different lengths, such difference being substantially
equal to the distance from centre to centre of the different tuft yarn carriers, guides
or needles.
In practice we find that but five rows of holes and five projections are necessary, as
the projection 2 may be omitted and the carriage rest against the pattern surface when
the needles care to be operative.
In Figure 1 the barrel 13 is shown as moved nearly into its extreme position toward
the front of the loom, the hook just commencing to act to turn the barrel. As the
barrel 13 is moved further toward the left in Fig. 1, and away from the projections 2
to 6*, the springs 8 act to draw all the carriages in the same direction until their stops 7
meet the rest 109, in which position the parts will be as in Figure 1 the tuft yarn in
all the rearmost carrier, guide or needles of the series of carriers, guides or needles
of that carriage being in position to be taken by the jaws G G of the arms G¹ G¹x,
the jaws and arms constituting clamps. The barrel 13 has a hole for each projection 3
to 6 inclusive and the pattern card by covering one hole in the barrel opposite the
series of projections of each carriage acts to arrest or prevent one or the other of the
said projections from entering the hole prepared for its reception in the barrel, and the
distance which the barrel and card will move the carriages backward from the breast
beam depends upon which of the projections 2 to 6*, is acted upon by the card. The
projections 2 to 6* respectively control the placing of the needles c to c³ respectively
in working or so that the tuft yarns carried by them may be taken by the nippers
which rise between the jaws G¹ G¹× as will be described.
In Figure. 3 wherein the barrel is shown as moved backward or away from the front
of the loom, the projection 5 is shown as acted upon by the card, thus placing the tuft
yarn carrier or needle c² of the series in operative position.
If the projection 6* were arrested the carrier or needle e would be in operative
position and if projection 2 the carrier or needle c would be in operative position.
Fig. 6 on a larger scale shows the lower ends of the series of tuft yarn carriers,
guides or needles with the tuft yarns protruding from them and with the yarn of the
Carrier or needle e caught between the plates G G of the clamps which as herein
shown are employed to draw the tuft yarns for a short distance from the needles,
holding them in a row while the nippers with the springs n, n separated and pointed
upward, are made to grasp the row of tuft yarns in the set of carriers, guides or
needles which have been placed as described in working position, a carrier or needle of
each carriage by the movement of the latter for a greater or less distance, placing in
working position that one of the series of needles containing the tuft yarn of the color
which it is desired that each carriage from one of its needles shall furnish in the
-production of "the transverse row of tufts to be made.
Fig. 16 shows an inclined board or plate provided with holes or eyes to guide the
tuft yarns t on their way to the carriages, when made as in said Fig., the said
board being used instead of the eyes 15 and the wire-like extensions of the carrier
or needles.
In the drawings herein shown I have represented clamps which may be employed to
seize and. draw from the tuft yarn carriers, guides or needles, the tuft yarns t
preparatory to cutting the said yarns in tuft lengths; the said tufts being thereafter
taken by the nippers which insert them through the warp. These clamps consist of
two straight-edged bars of a length at least equal to the width of the web to be woven,

page_text: and the ends of the said bars being firmly secured to the upper ends of two pairs of
short levers G1 G₁ which are separately pivoted by pins g to the two arms G2 of a
rock shaft G³ which is fitted to oscillate between centre screws g' g' or in bearings
secured to the side frames of the loom. These clamps have attached to their under
sides similar toothed plates g² g the teeth of which are made to enter between and
match with each other in such way as not to prevent the straight edges of the
clamps G G from coming together, the said teeth being for the purpose of separating
the tuft yarns. The said clamps have an opening and closing movement, and an
upward and downward movement. The upward movement is produced by means of
a cam G see Fig. 15, on the rotary main shaft S, of the loom, the said cam acting
upon a lever, G, which works on a fixed fulcrum g³, secured to the main framing of
the loom, and which is connected by a rod g, with one of the arms G³. The forin of
this cam G is shown in Fig. 15 which will enable its dotted outline to be traced in
Fig. 1. The downward movement is produced by the weight of the clamps themselves
and their connections. Their closing movement is produced by means of a cam G
which operates on a lever G7 which works on a fixed fulcrum secured to the loom-
framing, and which is connected by a rod go, with one arm g', of a rock-shaft Go,
which works between centre screws gg, or in bearings secured to the side frames of
the loom, and on which there are provided, near cach end, two oppositely projecting
arms 9° * which connect respectively, by rods e* c*, with the clamp-levers G¹ G₁
To produce the opening movement of the clamps, a spring glo, is applied to connect
the arm g', of the rock-shaft Gs, with the loom framing, as shown in Fig. 1. This
spring keeps the lever G7 close to the cam G*.
H. H are the cutters for cutting off the tuft-yarn. The front cutter H consists of
a straight edged blade the cutting edge of which is parallel with the breast-beam.
The rear cutter H* may have its cutting-edge straight and set obliquely to the edge
of the cutter H, or it may be of other usual shape. The stocks or bars H H¹*, to
which these cutters are attached, have their ends fitted to work in horizontal slide-
ways H2H secured rigidly to the side frames of the loom. These cutter-stocks have
imparted to them simply a direct forward and backward motion which is produced by
a single cam H³ which may be applied directly on the main shaft S, but is shown as
consisting simply of a wing-piece bolted to the side of the nipper-closing cam K.
The nippers for inserting the tufts into the web are shown in Figs. 1, 9, 11 and 12.
Their construction is best illustrated in Figs. 9, 11 and 12. Those portions of these
nippers which take hold of the tuft-yarn are represented as made of two thin steel
plates n, n of a length nearly equal to the width of the web to be woven, each plate
being slit, as shown in Fig. 11, to produce a number of prongs equal to the number
of tufts to be inserted into the width of the web, two corresponding prongs of the two
plates constituting a pair of nippers for one tuft. The said plates are riveted or other-
wise firmly secured at two or more points in their length to as many pairs of strong
jaws N N which are pivoted together substantially like the jaws of ordinary pinchers,
except that they are pivoted by one pivot consisting of a long pin n' which runs
through them all, and the ends of which are firmly secured to two arms n² which are
made with journals n³, to fit in bearings in the ends of two long arms №¹ of a rock-
shaft N, which works between centre screws n', or in bearings secured to the side
frames of the loon, the said arms n³, and pin n¹, forming a crank which turns in the
said arms N1, and for which the said arms N', constitute ascending and descending
supports. The said jaws N, are extended, as shown at n Figs. 11 and 12 for the
passage between them of the cams or conical wedges no, which are fast on a rod n
which is fitted to slide through the crank-journals n³, the said cams or wedges being
for the purpose of closing the lips or points of the nippers, which when not thereby
closed are held open by springs n³, applied between the plates n, and secured to the
pin n'. The nippers thus constructed and organized have movements of three kinds,
viz; one upward and downward with the arms N, of the rock shaft N³, one of a
semi-rotary character in bearings in said arms, and an opening and closing movement.
The upward and downward movement is produced and controlled by a cam I; the
semi-rotary movement by a cam J, and the closing movement and the opening

page_text: movement by a cam K, assisted by the springs n8, hereinbefore mentioned, the said
cams being all on the main shaft of the loom.
The form of cam I, which produces the upward and downward movement of the
arms N', and the nippers is shown in Fig. 1-3 and its outline is so dotted in Fig. 1
that by a comparison of the latter with Fig. 13 its position can easily be traced. This
cam acts directly upon a lever I', which works on a fixed fulcrum 3, in a stand I²,
bolted to the lower hack rail of the loom framing, and which is connected by a rod i,
with one of the arms N¹.
The cam J, which produces the semi-rotary motion of the nippers, by which when
they are raised they are caused to be presented points upward to take the tuft-yarns
as in Fig. 12 and when depressed are presented points downward to insert the tufts
into the web as shown in Figs. 1 and 9 operates upon a lever J which works on a
fixed fulcrum,j, secured to the left hand side frame of the loom, and which is connected
by a rod j¹ with an elbow lever J2, which works on a fixed fulcrum j* and connects
with the rear end of a sliding rack-rod, which is furnished on the front part of its
under face with a toothed rack which gears with and turns a pinion j fast on one of
the crank arm journals n³ and so turns the nippers to the extent of half a revolution
back and forth. This rack rod works transversely through the rock-shaft N2, and
under a guide-roller 3 secured to one of the arms N₁, and in order to provide for the
oscillation of the said rod with the rock shaft N, while retaining its connection with
the elbow-lever J, the said connection is made by a suitably-curved slot in the said
elbow-lever and a pin secured to the said rod as shown at j in Fig. 1.
The cam K, for producing the closing movement of the nippers, is shown in Fig. 8
and also in Fig. 1. It operates directly upon a lever K¹ which works on a fixed
fulcrum secured in the right hand side frame of the loom, and which connects by a
rod with an elbow-lever K, which is like the lever J2 but arranged on the opposite
side of the loom on a fixed fulcrum *. This elbow-lever K² has connected with it by
a connection just like je before described, a sliding rod. 2 which works transversely
through the rock-shaft, as shown in Fig. 7 just as the rod does. This rod works
through a guide on the contiguous arm N of the rock-shaft N2 and is furnished at
its front end with a pink which works in an oblique slot in the end of a horizontally-
moving lever K³ which works on a fulcrum on the contiguous arm N¹ of the rock-
shaft N and which is connected with the rod n². The movement of the sliding-rod k
in a backward direction produces a longitudinal movement of the rod n² in a direction
to force the cams or wedges n between the parts n³ of the jaws of the nippers and
thereby effect the closing of the nippers. The forward movement of the said rod k²
produces longitudinal movement of the rod n in the opposite direction, and withdraws
the cams or wedges n° and allows the nippers to be opened by their springs n.
It may be observed that since the rods and work through the rock-shaft N2 and
have slotted connections with their respective levers J and K, the operations of
turning the nippers and of opening and closing them are effected while they are being
raised and lowered by the oscillation of said rock-shaft.
The lay L may be operated by any suitable means, as for instance by a cam on the
main shaft S it moving a lever joined to a connecting-rod 13. The heddles and other
parts not heren described and represented in the drawings may be constructed,
arranged and operated as in other looms for weaving tufted. fabrics, or as in the
applications referred to. We-prefer to use a needle for inserting the weft, as that
does not require so great an opening of the shed as is required by a shuttle, and any
usual form of needle and means to operate it to carry the filling through the shed may
be employed.
The fabric produced in the loom herein described will be substantially such as shown
in British patent No. 1634 for the year 1881.
We have herein shown the tuft yarn carriers, guides or needles, as tubes held loosely
in pockets or spaces at the sides of the carriages, but we desire to have it understood
that the tuft yarns may be extended through openings made directly in the said
carriages, and led from one edge of the said carriages, so that they may be pulled
therefrom by the clamps or by the nippers themselves.

page_text: We have herein shown the clamps G G* as employed to seize the ends of the tuft
yarns and pull them out from the carriers, guides, or needles preparatory to cutting
the tuft yarns into tuft lengths, but we desire it to be understood that we may entirely
dispense with the said clamps G G* and instead move the nippers substantially as
shown in the said British application No. 13,684 making them seize the ends of the
tuft yarns protruding from the lower ends of the carriers, guides or needles.
In the application last referred to the clamps G G✶ and their operating mechanism
are entirely dispensed with and we desire it to be understood that our invention,
including carriages having tuft yarn carriers, guides or needles and a jacquard for
moving said carriages different distances in the direction of their length may be
employed equally well with the nippers shown in said application No. 13,684.
Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed, we declare that what we claim is :
First. In a loom for weaving carpets a series of carriages arranged side by side, a
jacquard to move them varying distances in the direction of the length of the warp
threads, and a series of tuft yarn carriers, guides or needles arranged in the said
carriages one behind the other in the direction of the length of the warp, combined
with cutting mechanism to cut the tuft yarns, and with nipper-like plates to scize the
ends of the tuft yarns and carry and place the tufts between the warps after they are
cut into tuft forming lengths, substantially as described.
Second. In a loom for the production of tufted carpets, a series of carriages arranged
side by side across the loom above the warp threads, and made movable in the direction
of the warp threads, and containing a series of tuft yarn needles, guides or carriers
arranged therein one behind the other in the direction of the length of the warp
threads, the needles, guides, or carriers of each carriage being supplied with yarns of
different color taken from separate spools according to the colors desired in
any one
longitudinal row of tufts, combined with a jacquard or pattern-surface and inter-
mediate devices actuated thereby, whereby the carriages are moved for different
distances preparatory to making each row of tufts, to bring any desired tuft yarn
needle, guide or carrier of each carriage into the proper line to have its tuft yarn taken
by any usual devices and carried through between the warp threads and be cut to form
a staple-like tuft.
