  • This beam F is lowered by means of its own weight, and is raised by means of two pairs of hooked rods 5 5 and G G, pivotally connected, one of each pair, at opposite ends of the beam. These rods have hooks like those shown in Fig. 13, and when the rods are at rest these TOO IIO
  • the beam B then descends, the downward movement-of the bobbin-beam F will not be affected, and it remains elevated until other tappet-pins o strike the upper ends of the catch-levers 7 7 and move their catches out of engagement with the rods 6 6.
  • the bobbin-beam then descends of its own weight. The bobbin-beam may thus be raised, lowered, and held in its upper as well as in its lower position.
  • J J are narrow metal bobbins upon which the ground warp-threads X are wound. These bobbins are mounted in annular bobbin-carriers K K, in which they are retained by studs r fr on the carriers which enter between the cheeks of the bobbins.

  • Each bobbin-carrier terminates at top and bottom in projecting feet t t, which enter in slots in the upper and lower bobbin-beams F F, whereby the bobbin-carriers are held and guided in place. Since the lower feet of the bobbin-carriers rest in and are held by the lower bobbin-beam, the carriers will be held in place thereby when the upper bobbin-beam is raised, so that the upperbobbin-beam may be raised clear above the upper feet of the vcarriers to enable the pile warp-threads to be passed over and between the bobbins.

To @ZZ whom it may concern:
Be it known that I, ANTOINE SIRET, residing at Roubaix, in the Department of Nord, France, have invented certain new and use ful Improvements in Looms for IVeaving Tufted Fabrics, of which the following is a specification. v
This invention is the subject of the following Letters Patent in foreign countries: France, No. 178,612, dated September 18, 1886; Belgium, No. 74,713, dated October 2,1886; Great Britain, No.12,543, dated October 2, 1886, and Germany, No. 42,835, dated October 15, 1886. This invention relates to looms for weaving pile carpets of the Smyrna kind and other similar pile fabrics, wherein the woolen or pile warps are tied around the ground warps, producing a pile of the Smyrna kind. In its general construction the loom comprises a series of bobbins, upon which the ground warpthreads are wound, said bobbins being journaled in carriers which are mounted in and between two vertically and independently movable beams, to which the bobbin-carriers are removably attached, so that the bobbins may be held in place alternately by each beam, in order that the pile warp-threads may be passed both above and beneath the bobbins. The pile warpthreads are each wound upon a spool-roller or bobbin, all of the said spools being mounted upon a rotary drum, by means of which they are brought into action as desired. The pile warp-threads are tied around the ground warpthreads, and after being so tied the weft-threads are shot in the usual manner, and are then beaten up. The several mechanisms for effecting these operations are all actuated by a series of hooked rods, which are brought into engagement in the proper sequence with a single verticallyreciprocating beam, which is in turn actuated by a treadle.
The loom is illustrated in the accompanying drawings, in which- Figure 1 is a vertical longitudinal section of the loom. Fig. 1a is a detail view of part of the mechanism shown in Fig. 1. Fig. 2 is a vertical cross-section of the loom. Figs. 3 ande are side views, looking, respectively, at

Referring to the first four figures, A is the frame-work of the loom, and B is the vertically reciprocating beam extending transversel y across the frame-work, which actuates the various mechanisms and which slides in vertical slots a i'n the frame-work. This 9: beam is weighted by weights b, so that it descends by its own weight, and it is raised by connection with a treadle O, suit-ably journaled to the frame-work. `The beam is pivotally suspended by pivoted links c from lever-arms d, rigidly'secured to a rock-shaft D, and the treadle is connected by a pivoted rod e to a lever-arm E, also rigidly secured to the same rock-shaft.
For convenience in describing the loom the roo treadle end of the loom will be considered the front.
F F are the two bobbiii-carrying` beams, extending` transversely across the loom beneath and parallel with the operating-beam B. Said beams F F are movable, vertically sliding on suitable guides on the frame-work. Then the loom is at rest, the lower beam F is supported in its uppermost position by pivio oted links j" j", the lower ends of which are held in slotted lever-arms f which are rigidly secured to a rock-shaft G, journaled in the frame-work beneath and parallel with the bobbin-beams, as best shown in Figs. l and 2. rlhevertical reciprocation of thelower beam F is effected by the rocking of the shaft G, and said shaft is rocked by the operating beam B, with which it is connected by means of four hooked rods 2, and t, the hooks 2o of which are at the proper times projected across the path of the operating-beam, but of these four rods three-1, 2, and Al-are ordinarily held out of co-operat-ion therewith by springs g g. 'lhree of these rods-wiz., l, 2, and t-have their hooked ends shaped, as shown in Fig. lt, so that when they engage the operating-beam they embrace the same,whe1'eby said rods are affected bythe movement of the beam in either direction, and the fourth 3o hook 3 has its hooked end shaped like that shown in Fig. 13, so that it is effected only by the upward movement of the operating-beam. 'lhe rods l, 2, and are all connected to the rock-shaft at one end of the same, as shown in Figs. 2 and t. The rods l and 2 are pivotally connected to the outer end of a downwardly-extending crank-arm 71 secured to the rock-shaft, and bot-h extend upwardly toward the operating-beam B, their upper hooked 4o ends being' held, when theloom is at rest, just in the rear of the path of the beam, and opposite its lowest position, such being the position shown in Fig. -l-. The rod 3 is pivotally connected at its lower end tothe outer end of i 5 an upwardly-extendingcrank-arm 7U, secured to the rock-shaft G diametrieally opposite to the arm 71. This rod passes in front of the operating-beam, audits upper hooked end is normally held in t-he plane of the path of the oper- 5o ating-beam, but above the upward limit ofthe movement thereof. The rods 2 and 3 are near their central parts bent toward each other, and they are held at all times in contact with each other by the spring g of the rod 3. Owing tothe location of the arms 7L 7l. on the shaft G, when the rods l and 2 are raised the rod 3 will be depressed, and when the rod 2 is swung forward to bring its hook into connection with beam B the rod 3 will be swung 6o away from the beam, and its hook will thus be carried beyond the pla-ne of the path of the beam. rlhe fourth rod is pivotally connected at the other side of the frame-work (sec Fig. 3) to a downwardly-extending crankarm 712 on the opposite end of the rock-shaft G, said arm being parallel with the arm 71, to which the rods l and 2 are connected. This rod extends behind the beam l?, and has its hooked end arranged in the same manner as these of the rods l and 2. If, then, any one of the rods l, 2, or 4 is swung forward at the proper time when the beam B is at its lowest position, thehooked end of such rod will cmbrace said beam, and the movement then of the beam will rock the shaftGbaek and forth, depressing the bobbin-beam F when the beam l is raised, and raisin g the bobbin-bcam when the operating-beam is lowered, as will be evident from an examination of Figs. l, 2, and 4; but if the rod 2l, when in its lewermost posi,- tion, has its hooked end projected across the path of the beam, so that its hook is engaged by the beam, said rod will only be affected by the upward movement of said beam, (oi ing to the shape of its hooked end, shown in Fig. 13,) and such. upward movement would cause the shaft G to be rocked in the direction to raise the bobbin -beam F to its normal position.
The movement of the rods il, 2,and l across the path of the opcrating-beam is effected by the following mechanism: In the rear of said rods is journaled, crosswise of the framework, a rotary shaft Il', carrying a ratchet wheel i. (1o-operating with this ratehet-wheel is a pawlj, pivoted toa link w, which is hung at one end upon the shaft ll, and the other end of this link is pivotally suspended by a rod 7;. from a lever-arm 7 on the main iockshaft D; hence each rocking of the shaft D rotates the shaft ll a certa-in uniform distance. As will appear hereinafter, a complete sequence of operations in the weaving is effected by eight depressions of the treadle, and hence the parts are so proportioned that the shaft ll will be rotated one-eighth of a complete rotation at each rockin g of the shaft D. To insure the shaft Il being held in the proper place at each movement, it carries au octagonal disk m, against the periphery of which presses a spring-actuated bar ln. The shaft ll carries a series of drums I, located at proper intervals, and on the periphcries of these drums are fixed tappet-pins o, one for each of the rods l, 2, and 4.-, as well as for other rods, to be referred to hereinafter. These tappet-pins al'e so located that at the proper moment cach will be brought in contact with its rod to swing the same across the path of the opei'atingbeani, and when said tappet-pins are moved away from their rods the rods will be returned to their normal positions by their respective springs y.
The upper bobbin-carrying beam. F' normally occupies its lowermest position when the loom is at rest, and it is held in this position by restin g on the bobbin-earriers, which are in t-urn supported by the lower beam F. This beam F is lowered by means of its own weight, and is raised by means of two pairs of hooked rods 5 5 and G G, pivotally connected, one of each pair, at opposite ends of the beam. These rods have hooks like those shown in Fig. 13, and when the rods are at rest these TOO IIO
hooks are in the rear of the lowermost position of the beam B,being held away from the same by springs (7. In proper order one of these pairs of rods is swung across the path of the beam by two of the tappet-pins 0, so that when the beam B ascends the bobbinbeam F is also raised. When the rods 5 5 are thus engaged by the beam B,the bobbinbeam drops on the descent of the beam B; but when the rods 6 6 are engaged' by the operating-beam and are elevated thereby they are held elevated by pivoted springlevers 7 7, having catches p p on their lower ends, which engage notches q q in the rods 6 6. Vhen the beam B then descends, the downward movement-of the bobbin-beam F will not be affected, and it remains elevated until other tappet-pins o strike the upper ends of the catch-levers 7 7 and move their catches out of engagement with the rods 6 6. The bobbin-beam then descends of its own weight. The bobbin-beam may thus be raised, lowered, and held in its upper as well as in its lower position.
Referring vnow to Figs. 5, 6, and 7, J J are narrow metal bobbins upon which the ground warp-threads X are wound. These bobbins are mounted in annular bobbin-carriers K K, in which they are retained by studs r fr on the carriers which enter between the cheeks of the bobbins. The outgoing end of each ground warp-thread passes out through an eye in one of the studs r and another guideeye s on the bobbin-carrier. These bobbins and their respective carriers supply the ground warp-threads, and are consequently equal in number to that of these threads. Each bobbin-carrier terminates at top and bottom in projecting feet t t, which enter in slots in the upper and lower bobbin-beams F F, whereby the bobbin-carriers are held and guided in place. Since the lower feet of the bobbin-carriers rest in and are held by the lower bobbin-beam, the carriers will be held in place thereby when the upper bobbin-beam is raised, so that the upperbobbin-beam may be raised clear above the upper feet of the vcarriers to enable the pile warp-threads to be passed over and between the bobbins. It is also essential for the weaving of the fabric, as will appear hereinafter, that the pile warpthreads should be passed beneath some or all of the bobbins and their carriers, and to enable this to be done it is necessary either that the bobbin-carriers should be lifted with the upper bobbin-beam, or should be supported thereby when the lower bobbin-beam is depressed. To this end the upper end of the upper foot t of each bobbin-carrier has a notch u cut therein, which, when the loom is at rest, is above the upper surface of the upper bobbin-beam. The notches on adjacent bobbin-carriers are arranged on opposite sides of the feet t, so that the notches alternate. The notches on both sides are engaged and disengaged by sliding serrated bars LL, which are mounted on the upper bobbin-beam, so as to be moved to and from the bobbin-carrier feet t. These sliding bars are connected with leverarms o o, which are secured to rock-shafts M M, journaled in brackets on the bobbin-beam. These rock-shafts are actuated byhooked rods 8 9, which are pivotally connected with lever-` arms w w on the rock-shafts M M. The upper ends of these rods have hooked ends of the character shown in Fig. 13, and they are arranged to be swung into cooperation with the operating-beam B by means of the tappets o o in the same manner as the hooked rods yalready described, and they are held normally out of co-operative position. b y springs g in the manner already described. The relative position of these rods 8 and 9 is shown in Fig. 2. Vhen in their normal position, when the loom is at rest, the sliding bars L L are out of engagement with the bobbin-carriers, and they are brought into engagement therewith only when the rods 8 and 9 are acted upon bythe tappet-pins. It only one rod 8 is acted upon, only one half of the bobbins will be affected thereby, and the other alternate half will be affected by the action of the other rod, whereas if both rods are acted upon simultaneously all the bobbins will be affected. When the bobbins an d their carriers are thus engaged, if the lower bobbin-beam is depressed the bobbins will beheld suspended from the upper bobbin-beam, and if when so engaged the upper bobbin-beam is raised the bobbins will be raised therewith.
The ground warp-threads pass forward over a roller N in the front of the loom and thence to the cloth-beam O. Between. the bobbins an d the roller N the ground warp-threads pass between the teeth 0c of the swinging hatten P. The hatten is pivotally suspended from a rock-shaft Q, mounted in the upper part of the frame. The batten is arranged so as to be shifted laterally a distance equal to double the distance between two of the warp-threads. This is effected by mechanism shown in Figs. 2 and 4. The shaft Q carries a cam y, of sufiicient size and shape to cause the hatten to move the proper distance, and this cam bearsL against a part of the batten frame. The shaft is rocked by means of lever .c and rod 2', which connect it with a hooked rod l0, to which the rod z is pivoted. This rod l0 has its end hooked in the manner shown in Fig, 13, and is brought into (3o-operation with the operating-beam B (away from which it is normally held by spring g) by one of the tappetpins o.
The woolen or pile warp-threads are all carried by a rotatingdrum R, journaled in the frame-work behind the bobbin-beams. This drum carries near its periphery and entirely around the saine a series of rotating bobbins or rollers S S, which are journaled in opposite ends of the drum, and which extend crosswise of the loom. Only afew of these rollers are shown in the drawings, but it will be understood that they will be arranged around the entire periphery of the drum.
There is a IOO IIO
pile warp-threml Y for each point of the surface of the fabric to be produced, and the pile warp-threads to form a series or row of points clear across the fabric are all wound upon a single roller S. XVhen one line of points has been woven in, the drum is then rotated to bring the next pile-thread roller into position, and so on. For obtaining designs in weaving, care must be taken to ar 1ange the threads of different colors upon each roller and upon the several rollers on the drum, so as to be only obliged to apply successively to the several rollers to obtain from each the lengths of thread for one line of points of the fabric, and to produce automatically by this means the desired design. The drum thus provided with the separate rollers permits of the production of designs on pile fabrics without the use of Jacquard apparatus.
rl`he drum is turned, after the formation of cach line of points, either directly by hand or, preferably, by being provided with a gearwheel D, which engages with a worm-gear o. on a shaft h', operated by a hand-wheel c. The drum is held stationary during the work by means of a spring-actuated bar l1', which bears against a four-sided disk c on the shaft b.
Thepropertenson is given to the pile warpthreads Y during the formation of the points by the clutch mechanism coacting with the pile-wa rp roller S in operation, which is shown in Figs. 4 and lfhFig. 1G beingafragmcntary vertical cross-section through the periphery of the drum. The sliding and rotary clutch memberg is adapted to engage the end of each roller S in turn, and it is brought into engagement therewith by means of a crank-handle fi. and shaft j', which is connected with the sliding clutch member by crank-arm 7s and lever l. As shown in Fig. lO, the pile-warp rollers S are, for the sake of compactness, staggered, and hence two clutching devices are necessary.
The proper tension is given to the clutch members by weights m', which are connected to cords n', which pass over pulleys o', and wind upon spools p on the clutch-shafts. Then t-he clutch members are out of engagement with the pile-warp rollers, they are held from being turned by the weights m by the `grip of the lever Z.
In order to apply tension to the particular roller S, in operation the crank-handle i', Fig. i, is turned so as to rotate shafty" in the direction indicated bythe arrowin Fig. 1G, thus moving crank-arm 1 in the same direction. This movement of the crank-arm oscillates the lever l', thus sliding the clutch member g toward and into engagement with the end of roller S. The weight m then acts upon the spoolp, exerting a force in the proper direction to give tension to the pile warp-threads on the roller S.
O11 the periphery of the drum, extending crosswise of the same, equal in number and parallel with the roller S, are a series of slats or rods T, (sec Fig. 10%) over which the pile warp-threads Y pass in being carried to the ground warp-threads, whereby the pile warpthreads are properly guided and directed.
The tying' of the pile warp-threads to the ground warp-threads is accomplished (scc Figs. SO and 3l) by carrying the ends of the pile warp-threads over the ground-warp bobbins to a point between the bobbins and the roller N, the pile warl'i-threads bein g equal in number to the ground warp-threads. lVitb their ends held above the ground warp, each pile warp-thread is then placed beneath one of the ground warp-threads, then over two ground warp-threads, and then down around one thread, and thence up, where the other end of the pile warp-thread isleft free. These general operations, which will hereinafter be more specifically set forth, it is seen consist of forward, upand-down, and lateral movements of the pile warp-threads, which nievements are effectedbymechanisms, as follows:
lleld in position in braeketsvq on the periphery of the drum R, and immediately in front of the guide-ba1"l`, is apile-warp-carrying bar U, the ends of which project on cach side beyond the drum. (See Figs. 8, 9, and lO.) To this bar U the ends of the pile-threads are nipped by a nipping-rod 1", Iiournaled on the bar U. In front ofl this nipping-rod is a groove s', over which the ends of the pile warp-threzuls are placed, and along which a knife is passed to render the ends of the threads uniform. This pile-carrying bar is free to be moved forward away from the drum toward the roller N.
Pivoted to one side of the frame at t (see Fig. 3) is a sway-beam V, which at its rear end is pivotally connected to a crank-arm u on a rockshaft lV. Secured to this shaft lV on opposite ends of the drum R (see Figs. 3 and t) are two oscillating arms A', to the upper ends of which are pivotally connected cam-shaped sliding arms I3', having forked ends fc', which rest on guide-rollers fw immediately in the rear of the projeetin g ends of the pile-carrying bar U.
In front of the pivotal point t of the swaybcam a hooked rod lll is pivoted thereto. This rod has a hooked end of the character shown in Fig. 13, and it coacts with the main operating-beam B in the same manner and is actuated by the same mechanism as the hooked rods already described. lVhen this ITO rod ll. is raised by the beam B, the sliding arms ll are moved forward, taking up the pile-bar U and carrying it forward and downward to the point :r (see Fig. l) above the ground warp-threads imniediately behind the roller N. The bar U remains in this position during the subsequentweaving, being held in position in, the forked ends of the arms B by the tension of the pile warp-threads, and is then retracted bythe lever y and rod y2, acting upon the sway beam V. (See Fig. 3.) The pile-bar U is carried forward in front of the groum'l-warp bobbins at a time when the upper bobbin-beam F is raised above the bobbin-carriers, so that the pile-bar passes above the bobbin-carriers and beneath the upper bobbin-beam. The pile-bar is also carried forward in front of the hatten and above the hatten-teeth, passing between the suspension-bars of the hatten-tooth bar. Vhen the pilebar is carried to its extreme forward position, where it rests on the ground-warp, the pile-warp threads are located between the hatten-teeth, as indicated in Fig; 1. rlhe movement of the pile-bar U in the proper path is determined by the curved or camshape of the sliding arms B. These arms move in the spaces between the upper and lower bobbin-beams at the ends of the same which are not filled with the bobbins, as shown in Fig. 2.
The vertical movements of the pile warpthreads are effected by means of a vertieallymovable thread-shifting frame O, located between the drum R and the bobbin-beams F F. This pile-thread-shifting frame, which is best shown in Fig. 2, consists of two rectangular slides a2 at opposite sides of the loom, which slide vertically in the framework, and these two slides are connected by two rods b2, extending crosswise of the loom. The rectangular slides are on their inner sides cut away to form openings c2, which constitute continuations of the space d2 between the rods b2. Vhen the pile-bar U is carried forward, it passes through the space d2 and openings c2, the sliding levers B passing through the spaces formed by the rectangular slides, Figs. 1 and 2. Accordingly, when the pile-bar is carried forward to the point 9c', the pile warp-threads Y are between the two rods h2, and any vertical movement of the shifting-frame C thus would cause the portions of the pile warp-threadsbetween the ground-warp bobbins and the drum R to be moved up or down. The shifting-frame C is suspended at its opposite ends by cords or straps e2, which pass over pulleys f2, and to which are attached weights D', which normally hold the frame when the loom is at rest in its most elevated position, being the position shown in Fig. 1. In this position the space d2 between the rods h2 is in line with the pile-bar U when held in operative position on t-he drum, and also with the upper ends of the bobbin-carriers.
The shifting-frame C', when lowered, is automatically raised by the weights D', and it is lowered by the following mechanism: Be-v neath the shifting-frame C and journaled in the main frame-work A is a rotary shaft E', carrying near its opposite ends two drums or disks g2, to each of which is secured ythe end of a strap i2, the other end of which is secured to the frame C. When the shaft E is rotated in the direction of the arrow in Fig. 4, the shifting-straps are wound upon the drums, thus depressing the frame. This shaft is connected to be thus rotated to depress the shifting-frame C nin two ways, either when the main operating-bar B is depressed or when it is raised. Referring to Figs. 2 and 3, 7'2 is a disk or drum 'secured to the extreme 'right of the shaft E', and to this is attached one end of a strap k2, which is partly wound around the disk or drum, so that when the strap is pulled it will rotate the shaft. The other end of this strap is secured to the lower end of a hooked rod 12, which passes through a guide-bracket Z2, the rod having a stop 'm2, coacting with said bracket to hold the rod in normal position. The hooked end of this rod is shaped as in Fig. 13, and it is normally held out of and is brought into co-operation with the beam B in the same manner as the hooked rods already described, so that when in eooperation with the beam B the elevation thereof will lift the rod and rotate the shaft E.
Referring now to Figs. 2 and et, n2 is a grooved pulley secured to the extreme left end of the shaft E. Secured to and partly wound upon said grooved pulley is a cord o2, which passes upward around pulleys p2 p2 to the highest part of the loom, and thence downward, where its other end is attached to a hooked rod 13, which itself constitutes a weight to hold the cord taut. This rod 13 slides freely in a vertical direction through a guide-bracket r2. The hooked end of this rod is shaped as shown in Fig. 15, being different from the previously-described hooked rods, and having a different action, not being acted upon by a spring or by a tappet-pin. Normally, when the loom is at rest, the hooked rod 13 is held elevated above and out of reach of the main beam B. The cord o2 winds upon its grooved pulley n2 in the same direction that the strap 7a2 winds on the drum J2, so that when the beam B, on being raised, unwinds the strap 7a2 the cord 02 is also partly. unwound. The unwinding of the cord 02 allows the rod 13 to drop until it occupies the position shown in Fig. 4that is, with its hook just below and in the path of the beam B. When now the beam descends, it comes in contact with the rod 13, still further depressing the same, and so still further lowering the shifting-frame Cf.
The diagrams Figs. 17, 18, and 2O show the three positions to which the shifting-frame C may be moved.
The lateral movements of the pile warpthreads are effected by the hatten, the operation of which has already been described, and also by longitudinally-sliding combs G G2, mounted on the lower and upper bobbin- `beams, respectively, on their sides next the drum R. The pile warp-threads are brought IOO IIO
into engagement with these combs by the vertical movements of the shifting-frame C. The mechanism for shifting these combs laterally is best seen in Fig. 12. Each comb is mounted on its beam by slots s2 and pins t2, so as to permit of Vtheir sliding, and each is connected by a pivoted link u2 to one arm of a bell-crank lever H pivoted to the beam, which is heldin either position toV which it is moved by a spring ri. On its other arm each bell-crank lever carries a laterally-projeeting stud 1v, which comes in Contact with two stationary tappets afi .112, fixed to the tramework, by the movements oi' the bobbin-bean'is. The distance between the tappets encountered determines the distanec which the comb is moved. The comb G on the lower beam F is moved the distance between two adjacent bobbins, Whereas the upper comb on the upper bobbin-beam is moved just twice as far.
As previously stated, the fabric is woven on this loom by sequences of eight depressions of the treadle, eight operations being required to complete each point. These operations are as follows:
First opcrotiou.-'l`he lirst depression ot the treadle causes the rods o t3 and 1l to be brought into gear with the movable beam l and the beam to be raised. This elevates the upper bobbin-beam F elear above the bobbin-carriers by means of the rods (i, and the elevation of rod 1lY causes the pile-bar U to be carried forward between the upper bobbin-beam and the bobbin-earriers to the point 415, thus leaving the pile warp-threads between the teeth of the batten above the ground warp-thread. The foot is then taken from the treadle andthe bealn l deseends. rlhe upper bobbin-beam, however7 remains elevated, being held up by the levers 7 7. At the end of this operation the parts are left in the position shown in Fig. 1 and in the diagram Fig. 17.
Second operation-Flic second depression of the treadle raises the beam B,with the rod 12 in gear. rlhis depresses the luie-threadshifting-frame C to the position shown in Fig. 1S, with the pile warp-threauls just below the ground warp-tlneads. \\'hen the beam l reaches the upper end of its movement, tappets strike the levers 7 7, thus releasing the upper bobbin-beam and permitting it to resume its normal position, as shown in Fig. 20. XVhcn the beam descends on the release ofthe treadle, it eomes in contact with the rod 13, thus further depressing` the shittingframe C' and causing the pile warp-thretuls to be engz'iged in the lower comb G.
Third operation-'Flic third depression ot the treadle raises the beam with the rods 2, S, and El iu gear. The rods S and il cause all of the bobbin-earriers to be engaged with the upper bobbin-beam, and the rod l causes the lower bobbin-beam to be depressed below the hobbincarriers. The descent of the lower bohbin-beam actuates the lower eomb G, moving it to the lett, (see Fig. 20,) and thus carrying the pile warp-threznls to the left oi and crossing the ground warp-threadslVhen the ireadle is released, the beam l again descends, and the hooked rod 2 again raises the lower bobbiu-beam to its normal position and the parts are leift as shown in Fig. 21. This movement also releases the rods S and 9.
Four/Hz operation.---l`he next depression of the treadle releases the rod 13, causing the shitting-frame C to resume its highest position, engaging the pile-threads with the npper comb G2 and raising their rear parts above the ground wari'J-threads. At the saine time the rods 5 5 and l0 are in gear with the beam l, so that the upper bobbin-beam is raised empty and the batten is shifted two places to the righi'. rlhe raisingI of the bol'ibin-bealn B also Causes the comb G2 to be shifted two places to the right, and as the pile warpthreads are now engaged by said comb they are shit'ted two places to the right, thus passing above and across two ground warpthreads, as indicated in Fig. The treadle is then released, the beam li descends, and the parts resume the position shown in Fig. 23.
Fifth operaitoit-Then the treadle is next depressed, the . rods 2, 13, 9, and 9 are in gear. The bobbins are thus suspended from the upper bobbin-liieam, the lower bobbin-beam is depressed, and the shifting-frame (2 is lowered, bringing the pile warp-threads between the teeth of the comb G. This movement carries the pile-threads down between the ground warp-threads. At the same time the descent of the lower bobbin-beam aetuates the comb G', moving it one space to thc lett, so that the pile warp-threads are crossed beneath the ground warp-threads. This phase of the work isillustratedin Fig. 2l. On then releasing the treadle the parts assume the po sition shown in Fig. 25, the pile wai'lrtllreads passing upward between the same ground warp-thretuls that they passed down between at the first movement.
These live operations complete the tyingof the pile wzup-tln'eads,th ey havin gbeen passed around the ground warp-threzulls in the manner shown in Fig. 29. 'l'he pile-barU is then disconnected from the pile warp-threzuls by separating from the threads the n ipping-rod o".
Sixth operation.--\Vhen the treadle is next depressed, the hooked rods 1,4, 5 5, and S are in gear. Rod S causes one half of the bob bin-carriers (the even numbers) to be connected with the upper bobbin-beam, rods 5 cause the upper bobbin-beam to be raised, and rods l and it cause the lower bobbin-beam, Carrying the other half of the bobbins, (the uneven numhers,) to be lowered. This separates the alternate ground warl'i-threads, as shown in Fig. 2t), and a weft-thread Z is then shot (see Fig. 31) and the treadlc is allowed to rise.
Serenth opera/.ionr-On the next de] 'u'ession of the treadle the hooked rods 1, et, 5 5, and fl are in gear. Rod i) causes the uneven-mint bered lrobbie-carriers to be connected and raised by rods 5 5 with the upper bobbinbealn, the even-numbered bobbin-earriers being lowered with the lower bobbin-beam, as shown in Fig. ,27 A seeond weft-thread Z2 (see Fig. 3l) is then shot and the ireadle lett free.
Eighth ope/'attoa.-\Vhen the treadle is depressed for the eighth and last time, the
IOO
hooked rods 1,4, 5 5, and 8 are in gear, the same as in the sixth operation. The bobbincarriers are separated, as shown in Fig. 28, and the third.weft-thread Z3 is shot, (see Fig. 31,) the batten is moved one stroke, and the treadle is left free. The pile-bar U is then placed below the rear parts of all vthe pile warp-threads, its edge being applied v.to the last weft-thread. rlhe pile warp-threads are then nipped by the bar r', and a knife is passed along the groove s2, thus cutting off the threads and leaving their ends projecting the same distance as the first ends. The pilebar U is then replaced on the drum, which is turned one space, and the loom is ready for weaving the next. point.
Each of the points of the transverse line of points thus completed has two tufts of the same length, and is similar to the Smyrna point, except that the two tufts are raised on different sides ofthe part of thepile-threads that lies across the two threads of the groundwarp, (sec Fig. 31,) whereas in the Smyrna point both tufts project up from the same side.
