. useful Machine for Setting Oarpet-I/Varps, of

which the following is a specification.

The invention has for its object the provision of mechanical devices for setting the tuft yarns (which form the pile on the carpet) on the wide bobbins used in weaving what are known in the trade as imperial AXminster carpets.

The invention consists of a jacquard or like apparatus working in conjunction with a winding machine and a frame or bank to carry any desired number of bobbins. The jacquard' raises or lowers or raises and then lowers the colored yarns as selected by the card in the usual known way the height desired so that cach selection of the colored yarns by each card is then wound on a wide bobbin separately (the width of the wide bobbins on which the yarns are wound being equal to the width of the carpet), The length of the colored yarn wound on each of the wide bobbins is as arranged according to the length of the pile of the carpet and the quantity of repeats of the design that is to be woven. The wide bobbins are afterwards arranged in the known manner on an endless chain and. operated upon by ingers or nippers in the loom in the manner usual in weaving` imperial Axminster carpets. In the past this setting of the colored yarns according to the painted design, has been done by hand labor. A frame being made to hold 190 or other quantity of bobbins, the end of the yarn of each bobbin on the frame is taken and arranged according to the design to be made, on one large bobbin 27 wide or more or less according to whether the carpet to be made is to be 27 wide or more or less, then the 190 threads are wound on to this wide bobbin, the length of the yarn wound being according to the number of yards of carpet to be woven.

The number of bobbins to be handled by the operator is very great, according to the length ofthe designthat is being made. For example, to set or arrange those wide bobbins for a design 36 long with 8 rows of tufts of yarn to the inch of the carpet, would I require the operator to arrange the frame of 190 bobbins by 36 by 8 equaling 54,720 operations. In our method we arrange in a frame 3800 bobbins more or less. We paint the design to suit any number or all of these 3,800 bobbins. In the jacquard we have 3,800 tail cords more or less each controlling one of the 3,800 colored yarn threads.

the jacquard operates so that when t-he lifts ofthe jacquard are raised 190 of the ends of the colored threads are presented to an arranged level.

Any mechanical arrangement can be used to grip the 190 ends and pull them over the large bobbins 27/ wide. I/Ve prefer to wind on to each large bobbin enough of the yarns f or one row and the repetitions thereof in the yards long, or even for say four to ive times this length of carpet, but obviously in place of using only onesuch bobbin for carrying such lengths of yarn two or more may be used. The attendant fixes those ends to the bobbin in the usual way and by the operation of a clutch lever causes the winding mechanism to act on the wide bobbin, which is rotated as many times as desired according to the number of yards of carpet that are to be woven. If a design is 36 long and there are 8 rows of tufts to the inch of the carpet, then the jacquard has to operate 36 times by 8 which equals 288 operations, compared with the hand manner of doing this before this invention, of 54,720 operations for the same size of design and quality of carpet to be made.

Another known way of Weaving of this carpet is by having a frame at the back of the loom with a certain number of bobbins in it. Each end of yarn of each colored bobbin is controlled by a jacquard tail or wire, but as the jacquard has to operate for each row of tufts or 288 times to the yard of carpet woven (if there are 8 rows of tufts to the inch on the carpet) it is a slow expensive method, compared to our invention, in which the jacquard in operating 288 times could set the tuft yarns to weave 400 yards of carpet thus doing 100 times the work.

carrier.

Fig. 4 is a transverse section of th'e bar which raises the yarn carriers and is shown in engagement with an extension of one of said carriers. Fig. 5 shows one of the tilters which are adapted to intercept the downward movement of the yarn carriers. Fig. 6 is an elevation of the jacquard or selecting machine and lever connections and Fig. 7 is an elevation (in part section) of the jacquard machine fitted on the top of the tuft setting and winding frame. Fig. 8 is an elevation of part of the tuft setting and winding frame with cams and connections for operating several parts of the machine. Figs. 9 and l0 are part elevations at right angles to each other showing the driving Fig. 11 is an elevation and Fig. 12 a plan' to an enlarged scale showing detail views of the gripper, while Fig. 13 is an elevation showing the guillotine also to an enlarged scale. Figs. 14 and' 15 are detail views of a disk hereinafter referred to.

As shown, the tails or cords J of the jacquard or tuft setter which is of ordinary construction, in lieu of carrying weights are each attached to a short pivoted lever t which we term ,a tilter. The several tilters are normally in an inclined position out of action,

but such of them as are operated by the card,

namely one in each row, are brought to a horizontal position as is indicated at t1 (Figs. 1 and 4), in which position each serves to intercept the downward movement of a corresponding' yarn carrier T and bringing said carrier to rest. The carriers T each carry a number of ends of yarns Y, in the present instance 20, which pass thereto from bobbins and are led through separate orifices in the carriers and held by tension springs as indicated to a larger scale at Fig. 2.

The jacquard machine has 20 rows of needles each row consisting of 252 needles. There are 20 rows of tilters t, and 252 tilters in each row. Each of the tilters is attached to a tail J connecting to an u right a, so that the needles a1 of the jacquar when operated on by one of the punctured cards a2 or design operate on the tilter through the tail on the colored yarn in the carrier as required to make the design, as has been arranged by puncturing the card in the usual known way.

There are 252carriers T across the machine and in each carrier there are 20 openings. ln each opening there is a spring s to act as a tension on each thread of colored yarn Y that is threaded through each of the openings.

At the back of the machine the usual bank or frame is arranged to hold 5040 bobbins on which are wound all the colored yarns, one color only being on each of the bobbins of the 5040, and the threads of vthose bobbins are threadedA through the openings of the carriers, each thread in a separate opening.

The tilters t are raised by the usual raising lifter a3 provided with knives a4 adapted to the yarn carriers T by means of the bar H, at

the period when a uncture card 0,2 is being pressed on the neet es a1; the hook h1 on the .other side is formed to catch on the tilters t that have been raised into the osition to catch them according to which tilters have been operated on by the knives a1 of the usual raising lifter a3; and in this way the colored yarns Y in thecarriers T as arranged for the design are brought to one level such that they may be engaged by a gripper G operated by mechanism hereinafter referred to.

As shown at Figs. @Tand 10, the first motion shaft F is rovided with a fast pulley F1 and a loose pul ey F and has also secured to` it a pinionwheel F3 adapted to gear witha spur wheel F1 on a shaft F5 on which are mounted' clutches Gzand' D2, the male portions of which are operated by hand levers and connections G1 and D1 to engage with the female portions which are loosely mounted on the shaft F5 andv which carry pinion wheels g1 and d1. The inion g1 gears with a spur Wheel g2 on a sha t 5], said spur wheel being arranged to o erate the gripper .G through` crank pin and lever connections G3. The pinion d1 gears with a spur wheel (Z keyed to ashaft D. The shaft D'has secured to it at each end cams E E1, (Fig. 8), which respectively operate the top and bottom knives of the guillotine K through lever connections 7c, and the shaft D also carries a cam E2 which operates (through lever connections L) the bar H adapted to engage with the yarn carriers T. By means of a chain m and chain wheels m1 the shaft D also drives a shaft MQ at each end `of which are securedcams N 1, M2, (Fig. 7), arranged to operate the jacquard orselecting mechanism through lever connections M3, M4, which respectively operate the raising lifter a3 and the jacquard card barrel.

In the operation of the machine 'The first motion shaft F drives the shaft F5 through the gear wheels F3 'F1 and by the attendant operatin the hand lever connections G1 the fema e portion of the clutch G2 is engaged by the male'portion and so communicates motion from the pinion g1 to the spur wheel g2 on the shaft y which spur wheel g2, through crank and lever connections G1, operates the gripper G which moves forward and grasps the 252 ends of colored threads placed in position and pulls them over asetting bobbin B centered on a spindle B1. The gripper mechanism is then automatically stopped through the action of springs g7 (Figi 9) disenga'ging the slidingmale portion of the connections G1.

clutch G2 from the loosely mounted female portion, the movement of which male portion of the clutch is effected when a recess 930 in a rotatable disk gr6 (of the type shown at Figs. 14 and 15) on the shaft g, comes opposite a roller g3 on the end of one of the lever The edge g31 of said disk g1 (Figs. 14 and 15) Vis arranged to keep the male portion of the clutch G2 in engagement with the female portion during one revolution of the shaft g, by contacting with the roller g3 on the lever connections G1 which operate the male portion of the clutch G2. The attendant now fixes, in the usual known manner, the 252 threads on the bobbin B, and opens by hand the jaws of the grippers G, after which the bobbin is set in motion and the desired number of inches of yarn is wound on the bobbin. Motion is communicated from the shaft F to the bobbin spindle B1 by a sprocket Wheel F20 and chain F21 gearing with a sprocket wheel B3 loosely mounted on the spindle B1 the face of which wheel B3 has recesses adapted to be engaged by pins B31 on a sliding clutch portion B4, operated by a hand lever B5. `When the desired number of inches of yarn iswound on the bobbin B, the winding mechanism is stopped by withdrawing by means of the hand lever B5 (Fig. 8) the clutch B4 from engagement with the loosely mounted sprocket wheel B3. The attendant now operates (through the lever connections D1) the male portion of'the clutch D2 which engages with its female portion against the power of springs d, and through the intermediary of the gearing (Z1, d, drives the shaft D and likewise the cams E E1 (Fig. 8), the latter (through the connections le) causing the guillotine knives K (shown particularly at Fig. 13) to cut the 252 ends of thread and return said knives to their normal position. The ends of the thread having been cut the bar H, and likewise the yarn carriers T, is raised by the cam E2 and lever connections L. The next card of the design is then brought against the needles (L1 by the action of the cam M2 and connections M1. Thereafter the raising lifter a3 is caused to actuate the selected tilters t, by means of the uprights a and tail cords J. The bar. H and the yarn carrier T are now lowered and each yarn carrier T is stopped by a corresponding tilter t whereby the desired color of yarns carried by it is brought into line with the gripper G. The shaft D then stops automatically on account of a roller (Z2, attached to one of the lever connections D1 entering a recess d3 in a disk d1 on the shaft D, thus releasing the male portion of the clutch D2 which is disengaged from the female portion by the springs d'1 (Fig. 10), the edge of the disk d4 having previously acted on the lever connections D1 during one revolution of the shaft in a si ilar manner to the disk gs, Figs. 9 and 10. he

`of the gripper to close.

bobbin B is now removed, replaced by an empty bobbin and the several operations repeated to fill a fresh bobbin.

The loosely centered jaws of the gripper G, particularly shown at Figs. 11 and 12, are arranged to be opened by operating a disk W- carries the upper knife of the guillotine K,

and releases the pawl thus allowing the jaws When the threads Y have been pulled into position, and fastened on the' bobbin B in the usual known manner7 the gripper aws are opened by manipulating a handle W4 on the rotatable disk W whose ratchet teeth are engaged by the pawl V1 to retain the jaws in the open position. The gripper jaws are loosely pivoted on the shaft .r andin their forward and rearward travel are supported at each end on a track :c1 by a roller x2 (Figs. 8, 10 and 12.)
