LOOM FOR WEAVING TUFTED FABRICS.

SPECIFICATION forming part of Letters Patent No. 468,479, dated February 9, 1892. Application filed December 20, 1890. Serial No. 875,339. (No model.)

To all whom, it Hwy concern.-

Be it known that I, ADAM BOLLENTIN, of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Looms for "Weaving Tufted Fabrics, of which the following is a specification, reference being had to the accompanying drawings.

The object of this improvement is the weaving of tufted fabrics in which the tufts are. looped or secured to the warp of the fabric, and especially the weaving of that kind of tufted fabric which is the subject of my. United States Patent No. 423,659, dated March 18, 1890, which consists of a warp and weft and a series of tufts, each of which completely encircles one warp-thread and is looped around the back of the next warp-thread at one side of that which it encircles.

In a loom embodying my invention the tufts are placed in the web of warps and looped around the warp by the combined operations of nippers which are carried with the lay and a reed the dents of which have a lateral movement, and it is in certain combinations, including these nippers and the reed and the means of operating them, that this invention principally consists; but the invention also includes certain novel combinations in which the lay and its operating mechanism and a cutting apparatus for cutting the tufts also constitute elements.

I will first describe in detail a loom represented in the accompanying drawings, embodying the invention, and. afterward point out its novelty in claims.

Figure 1 represents a front view of theloom with the front part of the framing and the tuft-yarn-supplying devices and tuft-cutting devices removed. Fig. 2 is a plan view of the loom with the top of the framing and the harness mechanism and tuft-yarn-supplying devices removed. Fig. 3 represents a vertical section taken in theline a; wot Figs. 1 and 2, viewed from the right, but omitting the picker-st-aif and its connecting-rod on the right side of the loom. Fig. 3* shows an end view of the lay and part of the shuttle mechanism. Fig. 4 is a rear view of the upper part of the lay and the reed andmechanism for produc ing lateral movements of the reed. Fig. 5

represents a transverse section corresponding with Fig. 4, taken in the line y y and viewed from the left. Fig. 6 represents a transverse section in the line .2 z of Fig. 4, viewed from the left. Fig. 7 is a front View of the tuft-cutting devices. Fig. 8 is a plan view corresponding with Fig. 7. Fig. 9 represents a vertical section taken at right angles to Figs. 7 and 8 in the line *2 Fig. 10 representsasection, parallel with Fig. 3, of a part of the loom-framing and shows a side View of one of the cams and part of the mechanism upon which it operates for opening and closing the nippers which insert the tuft-yarn in the web. Fig. 11 represents a side view of one of the cams and part of the mechanism upon which it operates for the purpose of producing a toand-fro movement of the nippers. Fig. 12 is a side view of one of the cams and part of the mechanism through which it acts for producing the operation of the harness. Fig. 13 isa side view of one of the cams and part of the mechanism through which it operates for pro.

dueing the movements of the lay. Fig. 14 is a side view of the cams and parts of the mechanism through which they operate for producing the lateral movement of the reed.

Fig. 15 is a side view of the cams and part of the mechanism through which they operate for working the shuttlepickers. In Figs. 10, 11, 12, 13, 14, 15 the several cams and the mechanism through which they operate are shown in positions corresponding with the positions of the several parts of the loom shown in Figs. 1, 2, and 3. are sectional views, taken in the same line as Fig. 8, of the lay and the tuft-nippers, showing the nippers in different positions. Figs. 19 to 25, inclusive, are diagrams illustratin the looping of the tut'tyarns around the war; Figs. 1, 2, 3, and 3* are on the same scale. The other figures are on a scale double that of Figs. 1, 2, 3, and 3*.

Similar letters and numerals of reference designate corresponding parts in all the figures.

A designates the framing the warp-beam, and a a the warp.

O O designate the harness, of which there are two leaves, the frontleaf being suspended by straps s from duplex levers 0* (1* and the of the loom; a,

rear leaf being Suspended from duplex levers C'* 0 by straps s. The said levers 0* (3* are fast to a rock-shaft c and the levers 0 O'* are fast to a rock-shaft c, the said rockshafts having their bearings in standards 0 on the top of the framingA and being geared together by spur-gears 0* c*, so that when one moves upward the other moves downward. The lower bars of the two leaves of harness are connected together by duplex cords 0 which pass under and partly around two pulleys 0 which are attached to brackets 0 secured to the lower part of the framing.

The harness is operated by duplex cams 0 arranged outside the'framing of the loom on the main shaft S, acting upon duplex levers G which work on fixed pivots c in brackets 0 secured to the framing of the loom, the rear ends of the levers (3' being connected by rods 0 with the arms 0 on the ends of the rockshaft 0.

B is the lay, the swords B of which are fitted to oscillate on a horizontal rock-shaft B supported in bearings in brackets 13 on the lower part of the framing A, and are provided with counter-balances B 011 rods 19 projecting from their fronts. This lay has given to it peculiar movements, as will be hereinafter described, by means of duplex cams B on the main shaft S of the 100m, the said cams operating upon duplex swinging arms B the upper ends of the said arms working on fixed pivots b in brackets 19, secured to the loomframing, and the lower ends of the said arms being connected by rods B with the layswords. The cams B operate directly to produce the backward movements of the lay, the forward movements being produced by strong spiral springs B one of which is shown in Fig. 3, connecting the swords B with the front of the framing. The cams B are of the form shown in Fig. 13, having three offsets 3O 31 32 of equal prominence to produce three complete backward movements of the lay during three successive quarters of a revolution of the shaft S, and a less prominent offset 34 between the offsets 30 and 32 to produce a shorter backward movement, the depression 33 between the offsets 32 and 34 not so nearly approaching the axis of the cam as the depressions between the offsets 34 3O 31. The body of the lay is box-like or hollow, as shown in Figs. 3, 5, and 6, and has a longitudinal slot b in the top and another longitudinal slot b in the back for the tuft-nippers e 6 (shown in Figs. 3, 16, 17, and 18) to work through, the said nippers, which correspond in number with the tufts in a row, being carried by a long fiat bar 6 and a long pivot 6 the ends of which bar and pivot are carried by hangers E, which swing from pivots 6 secured in the swords B of the lay, to permit the said nippers to have, besides their movements with the lay, a movement backward and forward within the lay through the shuttle-raceway thereof.

The tuft yarn or yarns may be supplied from a spoolor spools in any suitable manner. In the example represented, D designates a tuft-yarn spool, and D a carriage in which it runs, the said carriage being fur nished with guide-tubes d. represented as like those'in common use for presenting the tuft-yarns to nippers in looms for weaving tufted fabrics. There may be any number of such carriages and spools in my loom, and they may be supported in any suit able manner. I have in Fig. 3 shown only one such carriage and spool, the carriage being represented as attached to a hanger d, projecting forward from the upper part of the framing beyond the lay.

The tuft-nippers consist each of two members pivoted together by the long pivot e The members of which the rear jaws 8 constitute parts have their lower parts below the pivot all rigidly secured to the bar 6 before mentioned, the ends of which are rigidly secured in the swinging hangers E. The members of which the front jaws e constitute parts and which hang upon the pivots e have their lower parts below the pivot all connected together by a long bar 6 from each end of which there projects downward and backward one of two arms 6 which are connected, as shown in Figs. 16, 17, and 18, by two short links c with the upper arms of two small levers E, which are pivoted by pivots e to the hangers E. The lower arms of these levers Eare connected by two rods 1 with the lower ends of duplicate slotted levers E which are hung on pivots e from fixed brackets E on the framing A. The slots 6 in these levers E receive pins 6 which project from two nearlyupright levers E (see Fig. 10,) which are fulcrumed by pivots e to fixed brackets e on the framing A. These levers E are furnished with anti-friction rollers e ibearing against the cams E on the cam-shaft S, the said cams operating through said levers E rods E and levers E to close the nippers which, when allowed to do so by the cams, are caused to open by springs a applied to the levers E The upward movements of thenip pers forreceivingthetuft-yarns,carryingtheir ends through the warp and assisting i n thelooping of the tufts around the warp, are effected by the swinging movement of the hangers E, produced by the duplicate cams F (see Fig. 11) on the shaft S, the said cams acting upon anti-friction rollers f on levers E, which are pivoted at their lower ends to brackets f on the framing and the upper ends of which are connected by rods F with the hangers E. The downward movements of the nippers are produced by their own weight and the weight of the parts through which the cams operate upon them, but may be assisted by springs f applied to the levers F.

The letters 9 g g designate the reed, which is of peculiar construction to co-operate with the nippers for looping the tufts around the warp. The dents 9 instead of being rigidly connected with the upper and lower parallel This carriage is bars gg,in which they are held, areloosely connected, so that by moving the said bars lengthwise relativelyto each otherthe dents may have a lateral movement given to them. This loose connection in the example represented is made by grooving the lower edge of the upper bar 9 and the upper edge of the lower bar g to receive the ends of the dents and inserting transversely through the grooved portions of said bars small pins 9 which serve to properly space the dents which are placed between them. The upper bar 9 is fitted to slide in a guide 9*, provided on the lay-cap, and the lower bar g is fitted to slide in a groove in the back part of the body of the lay, as shown in Figs. 4, 5, and 6, and the said bars 9 g are connected together near their ends by levers G G, which are fulcrumed by pivots g in brackets 9 provided on the lay-swords and which have at their ends forks which receive studs 9 on the said bars, as shown in Fig. 4.

The bars g g being thus connected, when one is moved in one direction the other is moved in the opposite direction, and-their respective ends of the dents which are received within them move correspondingly. Such a movement is given to the said bars and the dents by means of an elbow-lever G, pivoted at g on a rigid hanger G dependent from the lay B, the upper arm of the said lever G being connected at g with the bar g through an opening 9 provided in the back of the lay, and the lower arm of the said lever G being connected with an upright sliding rod G which passes through guides 57'', provided on the lay, the upward movement of the said rod G to produce the movement of the bar g in one direction being produced by a cam G loose on the rock-shaft B hereinhefore described, upon which the lay swings, and the movement of the said bar g in the opposite direction being produced by a spring G Fig. 1, applied to the lever G. a

The rocking movement of the cam G on the rock-shaft B by which the operation of the rod is produced, is obtained from a pair of cams H H (see Figs. 3 and 14) on the shaft S, operating between the two arms H H of a yoke, which are firmly secured to a short rockshaft it, (see Fig. 2,) which works in bearings in a small stand h, secured on the back part of the framing, the lower arm H{ of the said yoke being connected by a rod 72. with the rear end of a lever 7L which works on a fulcrum It in a bracket h, secured to one of the lower cross-bars of the framing A, the forward end of the said lever being connected with an arm h on the cam G". In order to accommodate itself to the movements of the arm h", the lever IL3 is slotted, as shown at 72 in Fig. 3, where it receives the fulcrum h. This permits the lever to have a slight movement longitudinally.

To provide for the adjustment of the fulcrum 7& forward and backward, if necessary, to vary the movement of its farther end and thereby adjust the length of movement of the reed-bars g g, the bracket h is secured to the cross-bar of the loom by means of a clamp h", in which the said bracket is adjusted by means of a screw h".

The cutting apparatus by which the tufts are cut from the yarn presented through the guide-tubes d is carried by a carriage z' '6 2*, which runs across the loom on a stationary horizontal bar I, which is bolted through lugs i provided at its ends in two standards I, supported on the framing of the loom, the position of the said bar being a little in front of and parallel with that occupied by the guidetubes (Z of the spool-carriage for presenting. the tuft-yarns.

In Fig. 7 parts of the lugs & are cut away to expose the carriage to view.

The carriage z' i 2* is represented (see Figs. '7, 8, and 9) as consisting of a box 2', an upright plate 2', and a horizontal plate 4*. The box 1' is fitted with a dovetailed gib i and adj usting-screws 1' to the horizontal transverse bar I. The plate 2', which is of inverted-T-shaped cross-section, is bolted to the back of the said box 1', as shown ati in Fig. 9. The horizontal plate 2* is firmly bolted to the lower part of the plate 1', a space being left between them for two small spur-gears "i i and a small pulley 2'". The spur-gear i and. the pulley i are fast together and both turn freely on a bolt 2', by which the plates t" are secured together, and the spur-gear i which gears with that W, is fast on the rotary-cutter spindle i which is journaled in the said plates 1; i the said spindle being furnished below the plate 1" with a rotary cutter 2' which forms one blade of a pair of shears, the other blade 2' of which is secured rigidly by screws 1 to a downwardly-prejecting rib at the rear edge of the plate The cutting of the tufts is produced by the rotation of the cutter t" in contact with the cutter as the carriage is moved across the loom across the bar I, the rotation of the cutter 6 being produced by means of the pulley 1 running along a cord or band W, the ends of which are secured to lugs 2' secured to the lugs '5 of the stationary horizontal bar I, the band having one turn around the said pulley. The rotary motion thus given to the pulley z' is also given at the same time to the spur-gear and that gives motion to the spur-gear i on the cutter-spindle i I The movement of the carriage along the bar I is produced through a cord j, clamped between the plates 1' and 2", and which runs horizontally, as shown in Figs. 2 and 8, parallel with the said bar and around duplicate horizontal idler-pulleys j, attached to the standards I, (see Fig. 2,) and around duplicate vertical idler-pulleys j also attached to the said standards and in front of upright the ends of the lay.

tions and having their ends secured to the said pulleys. In Fig. 3 said cord j is shown in bold outline passing under one of the said pulleys J, and the direction of the other cord, which passes over the other pulley, is indicated in dotted outline. By turning the shaft J in one direction the cord j is caused to be wound on one pulley J and unwound from the other and thereby to move the cuttercarriage in one direction across the loom, and by turning the said shaft in the other direction the operation of winding and unwinding the cord is reversed and the carriage is caused to move across the loom in the other direction. This movement of the rock-shaft in one direction is produced at the proper time by means of duplicate cams J on a shaft J which is geared with the cam-shaft S by spurgears J and S, one on each of said shafts, to produce one revolution of the shaft J 3 for every two of the main shaft. These cams J operate upon duplicate levers J the rear ends of which are fulcrumed in stands 7' on the framing and the front ends of which are constructed with toothed sectors j, which are geared with pinions j on the shaft J. The two cams J are both alike of the form shown in Fig. 3. Their respective levers J are kept in contact with them by springs J Fig. 3, which connect them with the loom-framing, and these springs produce the movement of the cutter-carriage in an opposite direction to that of the movement produced by the cams. The cutters operate in both directions and cut one row of tufts, while their carriage moves across the loom in one direction and the next row while it moves across in the other direction.

The shuttle-operating mechanism is best shown in Figs. 1, 2, 3, and 3*. K K are the shuttle-boxes. L is the shuttle. 7c 7c are the pickers, which are connected by straps Z Z with levers m m, which are pivoted at 77, n to a rail n between the lay-swords, and are connected togetherby a sprin gn ,which always exerts a tendency to draw the said levers toward each other and throw the pickers toward the center of the loom. 0 is a rod arranged to slide lengthwise within the lay between the.

pickers in guides 0, provided in the lay. The length of this rod is such that it willj ust occupy the space between the two pickers when one is thrown back, as shown at the left of Fig. 1, and the other is thrown forward toward the center of the loom, as shown at the right of Fig. 1, the said rod being shown in the lastmentioned figure as having its ends cranked upward to bring them within the range of the pickers. This rod is for the purpose of movin g the pickers backward to positions in which they may be locked by spring-catches p p to The picker at the left side of the loom is shown so locked in Fig. 1. The said rod 0 is moved longitudinally for the purpose of moving back the pickers through the agency of a lever M, (see Figs. 1, 2, and 3,) which is fulcrumed on a pivot 19* on the lower rail n of the lay, the said lever being connected at its upper end with the said rod 0 by a rod 71 The said lever M derives motion from two cams N N (see Figs. 2 and 15) on the shaft S, which act upon the two arms q q, projecting in opposite directions from the upper part of an upright rock-shaft Q, which works in bearings in brackets q* on the back part of the loom-framing. From the lower part of the said rock-shaft projects an arm 1 which is connected with the lower end of the lever M by a connection which slides upon the rock-shaft B As no claim is herein made to the mechanism for operating the pickers, and as such mechanism does not differ materially from that in other looms, no further description of it is necessary. It will be understood that as the tension of the spring a always tends to throw both pickers, if both have been pushed back by the rod 0, it is only necessary to liberate the catch 19 or p of either picker for the spring to produce its operation. To provide for this liberation, there are provided on the shaft S two cams R R, which act on the rear ends of two levers rr, which are fulcrumed on pins 7' at the sides of the loomframing and the forward ends of which operate upon the arms 5 s of two horizontal rockshafts t t, which are supported in bearings on the back of the lay, the said shafts being provided with other arms a u, the ends of which are situated above the catches p p. The levers r 1" have applied to them spiral springs 11 c, which tend to depress their forward ends and hold their rear ends in contact with their respective cams, the cams being in such position when the lay is thrown back that the springs o u will be allowed to depress the forward ends of the said levers, so that the arms 5 s of the rock-shaft t 25' may pass over them, as shown in Fig. 3*,wherein the lay is shown in its extreme backward position, which it occupies when the shuttles are thrown. When the lay moves forward, its arms 53' pass clear of the levers r r.

I will now describe theoperation of the loom, first supposing the working parts to be in the position shown in Figs. 1, 2, 3, and 3* and the several cams in the relative positions shown, respectively, in Figs. 10, 11, 12, 13, 14, and 15, the shed being wide open, the nippers being withdrawn entirely within the body of the lay below the raceway and being closed, and the shuttle being at the left-hand side of the loom. During the rotation of the cams from those relative positions the lay is caused to be moved to the position shown in Fig. 16- that is to say, nearly half-way forward-by the back of the offset 32 of the cam 13, (see Fig. 13,) passing its bearing on the lever B and the concentric depression 33 of the said cam comes into action and keeps the lay for some time at rest in that position. During the short forward movement of the lay just described the forward and upward movement of the nippers through the raceway and through the warp is produced by the rotation of the cams F, while the opening of the nippers is simultaneouslyproduced by the springs 6 The lay and nippers are now in the positionshown in Fig. 16, the open jaws of the nippers having received the ends of the tuftyarns between them. \Vhile the lever 15 remains on the concentric portion of the cam B, below the offset 32, the nippers are caused by the cams E and F to first close and then move downward to the position shown in Fig. 17, and thus to take hold of the ends of the tuft-yarns and pull them down through the warp a distance equal to the length of yarn required for a tuft, and afterward to return through the warp less than half-way to the position shown in Fig. 18. Before the first rise of the nippers and their subsequent descent the dents of the reed have been sloping, as shown in Fig. l; but after the descentof the nippers, and before their rise to the position shown in Fig. 18, the bars 9 g of the reed are moved in opposite directions by the cams H H far enough to give the dents of the reed an inclination the reverse of that shown in Fig. 1, and the upper and lower warp-threads are thus caused to move so far in opposite directions that when the nippers rise the second time they carry up the ends of the tufts 011 the opposite sides of the lower warp-threads to those on which they carried it down, and .so they loop the said yarns under the said lower warp-threads. The reedcains H 11' then operate to move the dents of the reed half-way backthat is to say, to upright positions-and the harness-cams G at the same time bring the warp-threads to a level and the nippers open to let go the tuftyarns, and this brings the upper threads of the previous shed on the opposite sides of the lower threads to which they were situated when the tuft was inserted, and the tuftyarns are thus 'caused to surround those warp-threads which were previously at the bottom of the shed and to be looped under those warp-threads which were previouslyuppermost. The continued movement of the cam B brings its offset 34 into operation on the lever B and thus causes the lay to move backashort distance. \Vhile the offset 34 continues in operation the cutters are operated to cutoff the tuft-yarns, and the further movement of the cam B carries the said offset 34: beyond the lever B and so permits the forward movement of the lay to beat up the tuftyarns to the fell before any weft is inserted. The offset 30 of the cam B now comes into operation and throws back the lay while the crossing of the shed is com pleted. \Vhile the lay remains back a shot of filling is put in and beaten up bya forward movement of the lay, permitted by the offset 30 of the cam B, passing by the lever B The warp is again shed, while the lay is again moved back by the offset 31 of the cam B and another shot of weft is inserted. This second shot is beaten up by the forward movement of the lay, permitted by the offset 31 of the cam passing by the lever The lay is then moved back by the offset of the cam 13*, and the reed-cams Ill-I complete the movement of the upper and lower bars of the reed to bring back the dents to the same inclination as first described with reference to Fig. 1. The several parts of the loom are now again in the positions represented in Figs. 1, 2, and 3.

In order to render the actual operations of inserting and looping the tufts more intelligi ble by avoiding reference to any other parts of the loorn than those which actually perform the said operations, I will now briefly explain the diagrams Figs. 19 to 25, with reference also to Figs. 16,17, and 18. The diagrams Figs. 19 to 25'are front views showing nothing of the loom but a portion of the reed, the nipper parts of one pair of nippers, and a part of a tuft-yarn-spool carriage, including only a single yarn guidetube d. Four warpthreads a a a a are also shown in section. The parts in Fig. 10 correspond in position with Fig. 3, as hereinbefore described, the shed being open and the upper threads of the warp being to the right of the corresponding lower ones of each two, around which the tufts are to be looped, and the nippers being in their lowest position. Fig. 20 corresponds with Fig. 16, the nippers being represented as having passed up through the warp to take the tuft-yarn to. Fig. 21 corresponds with Fig. 17, the nippers being represented as having drawn off through the warp a sufficient quantity of tl1ftr5'filfl for a tuft. Fig. 22 shows the reed reversed and the tuft-yarn as bent in opposite directions against the upper and lower warp-threadsa 0 Fig. 23 corresponds with Fig. 18, showing the nippers as having taken the end of the tuft-yarn back into the warp and looped it around one of the lower warp-threads a of the yet open shed. Fig. 24 shows the nippers as having let go the tuftyarn and returned to their lowest position. Fig. 25 shows the dents of the reed as having been brought to an upright position, the shed as having been closed, and the warp-threads all in the same plane and the tuft-yarn as cut off ready to be beaten up, these changes of position of the parts having caused the warpthread a to carry down the yarn over the warp-thread (t so that the latter is completely encircledby the yarn and at the same time having caused the yarn to be left looped under the thread a. This completes the operation of putting in one row of tufts. These tufts are secured first by being beaten up and afterward throwing in and beating up the weft, (two shots, according to the example represented,) while the dents of the reed are still upright.

The operations of shedding and putting in the weft to complete the securing of a row of tufts should always terminate with the same warp-threads upward, and after these operations have been completed the reed is again moved to bring its dents and the warp-threads into the same position in which the previous operation of inserting the tuft-yarns commenced, as described with reference to Figs. 1, 3, and 10.

It is obvious that the loom might be organized by a proper change of cams to put in only one shot or more than two shots of filling between the successive rows of tufts.
