Application filed April 1, 1905. Serial No. 253,353

To all whom, it may concern;

Be it known that I, EDWARD PARUSZEWSKI, a subject of the German Emperor, residing at Kottbus, in the German Empire, have invent ed certain new and useful Improvements in Looms for WVeaving Tufted Fabrics, of which the following is a specification.

This invention relates to looms for weaving tufted fabrics.

One object of the invention is to provide a loom of this type in which a plurality of pattern-forming mechanisms, each comprising yarn selecting, feeding, cutting, and knotting devices, may be operated from a single keyboard.

The invention also contemplates the provision of improved means for operating each and all of said mechanisms from the keyboard.

It is also an object of the invention to provide a loom in which the several patternforming mechanisms embodying the instrumentalities indicated above are simultaneously shifted transversely of the warp by mechanism which is actuated by each keg.

The invention further purposes to furnish an improved pattern-forming mechanismviz., mechanism for selecting and knotting the yarn for use in looms of the type indicated.

With these objects in view the invention consists in the novel features and combinations of parts to be hereinafter described, and linall recited in the claims.

In the accompanying drawings, in which similar reference characters denote the same parts throughout the several views, Figures 1 and 1 in conjunction show a plan view of the improved loom in which the knotting devices of the different pattern-forming mechanisms are omitted for the sake of clearness, a portion of the keyboard being broken away. Fig. 2 is a side elevation, partly in section. Figs. 3 and 4 are two different elevations of the knotting mechanism, showing the parts in differentpositions. Fig. 5 is a detail of the knotting mechanism; and Figs. 6 and 7 are detail pers iective views of the knotting mechanism, showing the knot-forming grippers separated from their actuating devices.

A number of pattern-forming mechanisms a for knotting or tying the loops of i'ard are arranged side by side transversely of the warp-threads It, said mechanisms corresponding in number to the patterns in the repeat of the fabric. Each of such mechanisms comprises a set of yarn-holding reels and all the instrumentalities necessary to knot the desired pattern from the yarn thus held, as will be presently explained, and said reels and other instrumentalities of each mechanism are mounted on a suitable frame movable transversely of the warp-threads by means of rollers which move along a track supported on the loom-frame, as indicated, and by means of sleeves 54, threaded on a threaded shaft 53, as shown in Figs. 1 and 2.

In the figures just mentioned an entire pattcrn-knotting mechanism is shown, together with part of a second one, it being understood, however, that the number of such mechanisms used in the loom is theoretically unlimited. All the mechanisms a are actua ted simultaneously by one and the same keyboard w in order in each mechanism to select the color of yarn to be used for the time being and to feed it to the knotting devices. The yarns of different colors are wound upon reels or cops 22 in each mechanism and are led thence to 'arn-presenting disks 17, having peripheral openings through which the strands of yarn protrude, being held lightly in position by means of spring-actuated pressers b in such a manner that the; can be readily drawn out and unwound from the cops 22.

It is necessary that by the pressure upon one of the keys of the keyboard 10 all of the yarn-presenting disks 1? of the different pat tern-forming mechanisms shall be simultaneously so adjusted as to present the yarn of the required color to the feeding nteans, by which the sante is carried to the knotting devices of each mechanism a. In the arrangement shown in the drawings the feeding device is designed to act upon the yarn held at the lowermost part of the disk 17. Said feeding ireans is illustrated as a gripper 2, by means of which a certain length of yarn is drawn out of the disk 17 in a manner to be presently described in order to be looped and knotted about two of the warp-threads. The adjustment of all the disks 17 for this purpose is effected from the keyboard 10, as follows: On pressing down a key 1 (each of which is advantageously indicated by means of a piece of yarn of a color which is selected by the disk 17 upon the depression of the key) an elbow-lever 2, moved by the key, and a slide 3, actuated by said elbow-lever, cause the upper end of an upright rack 4 to be moved rearwardly against the action of a spring 20,

the rack, which is guided in vertical direction 1 eratively connected with the shaft by inby a roller 5, being thus partly rotated about a gear-wheel 6, with which it engages. Each rack is provided at its lower portion with a nose or catch 7, said noses being arranged at different heights on the several racks. The parts 1, 2, 3, 4, 6, and 20, as shown in Fig. 1, are of a number corresponding to the number of yarn-colors. The gear-wheels 6 are all mounted loosely on a common shaft B and each is fixed to a disk 10, provided with a peripheral lug 9, as shown in Fig. 2. A bar 11 is adapted to rock the shaft of the gear-wheels 6 by means of perforated ears which are keyed to said shaft at its ends, said bar 11 extending completely across the keyboard and normally abutting against the lugs 9 of the several disks 10, as shown in Fig. In front of the racks 4 a knife-like bar 8 is continuously reciprocated to a uniform extent in a vertical direction by means of the driv ing-shaft of the machine, with which it is con nected by suitable transmission devices, such as those indicated.

When one of the keys is depressed, the corresponding rack is by the ab ove-described arrangement swung forward at its lower end, so that the bar 8, according to the position of the nose 7 with respect thereto, will sooner or later engage said nose during its upward movement and will as a consequence elevate the corresponding rack to a greater or less degree, thereby causing the corresponding gearwheel 6, with which it engages, to be turned to a corresponding extent. The lug 9 of the disk 10, which is adjacent such gear-wheel, is thereby made to rock the bar 11 to the same extent as the gear-wheel, such extent being, as before stated, dependent upon the height of the nose or projection 7 on the corresponding rack. The bar 11 actuates, through the shaft B a chain-wheel 12, which is fixed to said shaft and from which partial rotation is transmitted to the yarn-presenting device 17 by means of a chain 13, chainwheel 14, shaft 15, and gear-wheel 16, which latter is engaged with a toothed ring on the disk 17, so that this disk is thereby set in such position that the yarn of the desired color arrives at the lowermost point opposite the tongs or gripper z. The parts are thus held in adjusted position so lon as the corresponding key is held down, this being insured by a notch 18 in the rack 4, which catches upon a fixed bar 19, suitably mounted in the loom-frame. Therefore so long as the key is not released the disk 17 maintains its position and loops of the same-colored yarn will be continuously cut and knotted. When the key is released, spring 20 pushes the rack 4 away from the bar 19, and a weight 21, acting upon the shaft 15, carries the wheels and disk 17 back into initial position. All of the yarnpresenting devices 17 of the mechanisms (1 are operated in the same manner, being opin Figs. 3 and 4.

strumentalities similar to those just described, so that upon the actuation of said shaft by one of the keys the same color of yarn will be presented by each of the presenting devices.

After the knotting of each loop each mechanism a must be shifted transversely of the warp-threads k for a distance corresponding to two of said threads, as the knot is formed about two tlneadsf-This lateral shifting is also effected by the depression of the keys, and hence will be described before the knotting devices. A bar 23 extends transversely under all the keys, as shown in Figs. 1 and 2, so that upon the depression of a key 1 said bar is made to move a lever 24, 'so that by means of a lever-25 and slide 26, arranged at one end of the keyboard, the last rack 27 is moved in the same manner as was described with reference to the racks 4, serving for the selection of the color. By means of the rack 27 a gear-wheel 28 is rotated, to which wheel is fixed a crank-disk connected by a pin 29 to a connecting-rod 30, as shown in Figs. 1. and 2. The rod 30 is connected to a lever 31, by means of which one member 34 of a toothed clutch K is made to engage the other member 33, fixed on the driving-shaft 32, when the gear-wheel 28 is turned by the depression of a key in the manner described. By this means the shaft 35 is coupled to the shaft 32, and the resulting rotary motion of the former shaft is transmitted, by means of bevel- gears 36 and 37, chain-wheel 38, chain 39, and chain-wheel 40, to the shaft 41, which extends transversely of the warp-threads at the upper portion of the loom above the several pattern-forming mechanisms a. By means of the shaft 41 a reciprocating motion is imparted to a ratchet-pawl 51 by means of a crank-disk and connecting-rod 49, the pawl being thereby made to turn the ratchetwheel 52 through a certain distance at each forward motion. The ratchet-wheel 52 is fixed upon the threaded guide-spindle 53, on which the threaded sleeves 54, fixed to the frames of the mechanisms a, are mounted, as hereinbefore described. The ratchet-gear, the pawl 51 of which is formed double in order to'operate in either direction, serves to shift the mechanisms at to the extent of two warp-threads in the direction of the weft after the formation of each knot.

From the shaft 41 the shafts 47 of the pattern-forming mechanisms receive their rotary motion by means of the bevel- gears 42 and 43, shaft 44, and bevel- gears 45 and 46. On each shaft 47 are arranged the cams by which the knotting devices of each patternforming mechanism are operated, as shown Said knotting devices, as shown in Figs. 3, 4, 5, 6, and 7, consist, essentially, of the feed-grippers 2, already mentioned, which draw the end of the yarn from the presenting-disk 17, the shears s, which cut it off, the two cranked loop-forming grippers g and which seize the ends of the yarn length and pass the same downwardly through the warp-threads, so as to include two of the latter, and a middle knottinggripper 772, which seizes the ends of the yarn length when passed through such warpthreads draws them up between said threads, and draws the loop thus formed by a locking motion toward the finished part of the fab- The two loop-forming grippers g g are held in bearings 55 and 56 at the upper and lower portions of a rectangular frame 57, which slides vertically in a guide 88 of the loom-frame. The intermediate gripper m is also mounted on the frame 57 and partakes in its vertical reciprocating motion, which is imparted to the same by means of a cam 58, fixed on shaft 47, and a rod 59. The action of the frame 57 is such that the same remains stationary in its highest position during the first quarter-revolution. of the shaft 47, then descends during the second quarter revolution, then remains stationary in its lowermost position during the third quarterrevolution, and finally rises again during the last quarter-revelution of said. shaft. \Vhen the frame is at a standstill in the high ist position, the grippers g g are in the position shown in Fig. 3, in which the middle gripper 'm is, however, supposed to be open. The feeding-gripper 2 is also open, and the shears s are at their greatest distance from the yarn ends While the frame 57 is still stationary, the rotation of shaft 47 causes, by means of the cam 60, rod 61, and elbow-lever 62, the gripper 2, which slides on a slide-bar 63 in a guide 64 of the loom-frame, to be pushed toward the yarn end f. 'loward the end of this movement the catch 65, which holds the feerling-gripper open, bears against the fixed pin 66, whereby the movable part or linger 67 of said. gripper is released, and the gripper then closed by the action of the spring 68. The gripper 2 thus grips the yarn end and draws it during the subsequent backward motion between the grippers g At the end of the return stroke aft r the knot-forming grippers g 9 have seized the yarn the inclined. end of the part 67 of the feeding-gripper strikes against a fixed pin 67, whereby said gripper is again opened and is then held open by engagement with the spring-actuated catch 65.

During the movement of the gripper 2 a slotted slide 69, which is actuated by the shaft 47 by means of a cam 7 O, has seize the pin 7]. of a plate 72, Figs. 3, 4, and 5, which slides in a guide 7 3 of the frame 57 and carries said plate downwardly. In this movement a pin 7 4 of said plate 7 2 bears againit the incline of catches 76, which are thus disengaged from pin 77 of the movable part of the grippers g so as to release said grippers. As a consequence said grippers close under the action of spring 79 and some the yarn laterally in the manner indicated in Fig 6. At this moment the gripper 2 is opened in the manner above described.

As soon as the grippers g and g have seized the yarn near its ends and the feeding-gripper 2 is opened the shears s are moved in their guide 83 toward the yarn and back again therefrom by means of a cam 80, red 81, an-l elbow-lever 82, as shown in 3. During this movement a fixed pin 84 slides .in the angular lo t 85 of the shears arms 86, and thereby the shears are opened during the forward motion an closed during the backward motion, so that the yarn is thereby cut off in front of the disk 17.

During the second. quarter-revolution of the shaft 47 the frame 57, together with the grippers g, g, and m, moves downwardly. During this motion a pin 90, fixed to a bracket 89 of the framing, slides in the helical groove 91. of a cylinder 92, connected to the upper portion of the gripper g. The gripper 9 thus d escribes a semirevolutien, which is transmit ted, through gears 93 and 94, to the gripper g wnich movement is indicated in Fig. 5 by dotted arrows. In consequence of the crank form of the grippers at their lower ends said ends do not rotate upon their axes, but describe an are about the longitudinal axes of the upper on s of the grippers, so that the gripping ends turn in opposite directions an i bring together the ends of the yarn length, so as to f arm a loop, as shown in Fig 7. This rotation of the loop-f, -ming grippers is already completed at the first half of the downward moven'ient, so that the gripper ends and the yarn length are already cisposed at a height of about ten i'nillimeters above the warpthrea l in the position shown in Fig. 7. During this rotation of the loop-forming grippers a pin 95 cl the intermediate gripper m slides in an oblique slot 96 of the frame 57. By this means the intermeiate gripper we receives a rocking motion at right angles to the face of the (tick 17, with the pin 97 of the guide-r; d 98 as a pivot, until the en s of the mid le gri per pass between the two loopfnwning grippers g 9*, as shown in Fig. 7. During the following second half of the downward motion of the frame 57 the grippers g and together with the bent yarn length, p are through the warp-threads in the manner shown in Fig. 4, thereby laying the middle part of the length over two warp-threade and taking the two end; of tl'iese warp-threads downwardly. As the spring 99 yields during the downward motion of the frame 57 the intermediate gripper m also descends through l the warptln'eads, passing between the two warp-th earls over which the lateral grippers I liy the yarn length, as shown in Fig. 4. Durl ing the third quarter-revolution the frame 57,

with three grippers, remains in this lowest position. The pin 71 of the plate 72, which during the downward motion of the frame 57 can slide in the slot 100 of the slide-piece 69 without altering the relative pcsiticn between said plate 72 and said frame 57, is now seized by the slide 69, which draws the plate 72 upwardly. During this movement the plate 72 strikes against the nose or lug 101 of the catch 102, which holds open the middle gripper, and in thus disengaging sai catch causes said middle gripper to be closed by a spring 103, so as to grip the two yarn en. During the further upward motion the plate 72 strikes against the incline 104, Fig. 3, 0f the grippers g and 9 thereby opening these somewhat, so that they release the yarn.

During the fourth quarter-revolution of the shaft 47 the frame 57 with the three grip pers arrives upwarcly, the grippers retaining during the first half of the upward motion the samerelative positions, the gripper m drawing the ends of the yarn lengths upwardly, so as to form a knot. Said gripper is drawn upwardly by the spring 99 until the pin 105 strikes against the fixed framingpiece 89. As the frame 57 moves still farther upward, the pin 95 of the intermediate or middle gripper slides in the slot 96 of the frame 57, which causes said gripper to swing back into its original position, thereby bringing the completed yarn loop or tuft close up to the part of the fabric which has already been formed, as shown in Fig. 3. In the meantime the loop-forming grippers turn back into their original position in moving in openings 111 of the plate 72, which openings have curved surfaces formed eccentrically to the axis of rotation of said. grippers, so that said grippers are therebycompletely opened again. In this position they are held by the catches 76. Before the abovedescribed operation recommences the middle gripper m is opened again by means of a pin 106, which is moved upwar ly by means of a cam 107 and a rod 108 and which slides against an incline 109 of the movable part 110 of said. middle gripper, and this is then locked in open position by means of the spring-actuated catch 102.

The knotting devices of all the patternforming mechanisms (1 are simultaneously operated in the manner set forth by their connection with the operating-shaft 41 through the shafts 44 an 47, said. operatingshaft 41 being actuated from the keyboard,
