14 Claims. (Cl. 139-55) This invention relates to a novel method and appa ratus for weaving fabrics with a quilted or raised effect, and more particularly, it relates to an improved loom arrangement utilizing both a jacquard and dobby head for weaving new types of raised or quilted weaves of the Marseilles type and especially for producingvlarge designs Where substantially an entire bedspread constitutes one repeat of the weave pattern.

These weaves or other fabrics of this general type, are well known in the art of weaving. The designs woven into the fabric, which are brought out by the raised or quilted portions lend an attractive appearance to this material and make it highly desirable for bedspreads and many other purposes. However, despite its many useful and attractive qualities, the current production of this fabric has been greatly curtailed by the high manufacturing costs involved. These high costs are due principally to the operation of cumbersome and complex looms heretofore required to weave this type of fabric. Because of their complexity, the known type looms are not only subject to frequent break-downs but operate at relatively slow speeds. In addition, they are pick and pick type looms. As is known, such looms with jacquard heads require a large number of jacquard cards and as a result, there is diliculty in handling them. Also with a pick and pick loom it is impossible to achieve the automatic features of continuous operation which are a prerequisite for economical production.

Accordingly, it is an object of the present invention to provide a method and apparatus whereby raised or quilted fabrics may be conveniently and economically produced.

Another object of this invention is to provide a method and apparatus for weaving raised or quilted fabrics which may be easily modified to provide a wide range of patterns and designs.

A further object of this invention is to provide a method and apparatus for weaving a raised or quilted fabric of the Marseilles type without requiring a pick and'pick type loom.

These and other objects of this invention are attained by a novel loom arrangement including both a jacquard and dobby attachment. By the integrated operation of these attachments, certain of the warp ends carried by the loom are selectively raised and lowered on each pick of the loom. In addition, the dobby is utilized to control several other functions customarily controlled by the jacquard attachment, as for example, the advance ment of the jacquard cards and the activation of the jacquard lines controlling the selvage warp ends.

For a more complete understanding of this invention reference may be had to the following detailed descrip-l Fig. l is a perspective View showing the essential parts' of the improved loom utilizing a jacquard mechanism and dobby mechanism, and with certain details thereofy shown schematically;

Fig. 8 is a chart showing the jacquard card arrangement and illustrates a typical raising and lowering sequence of some of the jacquard controlled warp ends,

Referring to Fig. l, a loom 10 is equipped with a jacquard head 11 and dobby attachment 12. These parts are of conventional design and by themselves do not form a part of this invention.

The loom 1) as illustrated, is a 2 x l box loom with a single fixed shuttle box (not shown) on the magazine side of the loom and two interchangeable boxes 14 and 15 on the left-hand side of the loom. Each of the boxes i4 and 15 house a separate shuttle, and each of the shuttles contains a different kind of filling yarn. As is well known, by the operation of the conventional box motion, at predetermined intervals one or the other of the shuttles is propelled through the shed by a picker stick 16 on each pick of the loom. With this 2 x 1 box arrangement, a shuttle change can be initiated only by the box motion on even numbered picks and when the shuttle comes to rest on the left-hand side of the loom. However, this limitation is compensated for by the fact that this type of box motion is much less complicated and is'easier to operate than a pick and pick type loom. In addition, this type of loom can be equipped with the various automatic motions facilitating continuous operation of the loom, which is impossible with a pick and pick loom. lt is to be understood, however, that other types of looms and box motions may be used in this new loom arrangement if so desired.

The dobby attachment 12 has pivotally mounted jacks or harness levers 20, any one or combination thereof are pivoted towards or away from the loom on each pick.

The movement of the individual jacks 26 is controlledA in the conventional manner by means of a code in the form of a prearranged disposition of pegs 2 in holes 21a formed in a code bearing carrier, that is to say, the bars 22 of a harness chain 23 (see Fig. 2). The harness chain 23, which is omitted from Fig. 1 in order to simplify the drawing, is carried by a grooved cylinder 24 rotatably mounted just beneath a row of levers 25 which serve as the code sensing means. The levers 25 in turn, are connected to the jacks 2t) so that when the former are raised, the corresponding jacks Ztl are pivoted. By means of gears 28, the cylinder 24 is rotated a distance equivalent to the space between each bar 22, on each pick of the loom if a single index dobby is used, or on each alternate pick if a double index is used. Thus selected levers 25 are raised depending upon the disposition of the pegs 2l in the chain.

In the illustrated apparatus, two of the dobby jacks 20a and 2Gb control by conventional means the raising and butV formed independently, from sheds formed by the jacquard ends.

With reference to Figures l and 3, it will be seen that the jacquard `head 1l rotatably mounts a square faced perforated cylinder 33 about which is passed a code bearing `carrier in the form of a connected series of the usual rectangular shaped, perforated cards 34 (shown only in Figure 3). Each of the cards 34 correspond in shape and size to the four sides of the cylinder 33. The jacquard head 11 also supports a parallel series of needles 35, the forward ends of which project an equal distance through a needle board 36. The needles 35 serve as code sensing means. On each pick of the loom 1t), the cylinder 33 and one of the perforated cards 34a is brought into contact with the forward ends of needles 35, and thereby certain of the needles are depressed. The needles 3S are connected in the conventional manner with a plurality of jacquard lines 33 which in turn are connected with the warp ends carried by the loom it). Thus, depending upon which of the needles 35 are depressed by the cards 3d, a

selected group of jacquard lines 33 are raised on each pick of the loom, forming the desired shed of the warp ends.

As the cylinder 33 and an associated lantern gear 43 are moved away from the ends of the needles 35, a pawl 40, pivotally mounted at 4l on the jacquard frame 42, engages the lantern gear 43 causing it land the cylinder 33 to be rotated clockwise 90. Thus, during the normal operation of the loom, a new card is interposed between the cylinder and needles on each pick.

As mentioned above, with normal operation of a jacquard loom, one card determines which of the warp ends are to be raised on each pick, and consequently in the conventional jacquard arrangement, it is necessary to have as many cards as there are picks in one repeat of thev weave. ln the applicants loom arrangement however, the pawl 40 is connected to one of the dobby jacks 2Go by means of a wire 45, and when the jack Zilc is moved, the pawl 40 is raised out of engagement with the gear 43. When this occurs, and the cylinder 33 with its associated lantern gear 43 is moved away from the needles 35, the gear 43 is not in engagement with the pawl 4t' and thus the gear and cylinder are not rotated 90 degrees. between the cylinder and the needles on the next pick. By a suitable prearrangement of the pegs 2l in the dobby harness chain 23, the pawl di? is raised whenever a repeat in the shed formation occurs. By utilizing the same card for a series of consecutive picks, the number of cards which would otherwise be required is greatly reduced.

It is to be understood that this cylinder check motion may be modified so that the cylinder is rotated in the opposite direction (and thus move the cards backward instead of forward) if so desired.

The jacquard head ll also has a special mechanism indicated generally at 4d in Figure l and, in greater detail in Figure 4, for raising and lowering the jacquard lines 38 which control the warp ends forming the selvages in the fabric. In this mechanism a V-shaped lever 49 is pivotally mounted on a rod which in turn is supported by adjustable brackets 5l. `@Vith reference to Fig. 4, it will be seen that one end of lever 49 is connected to the rearward ends 35a of several of the needles 35. The other end of lever 49 is connected by a wire 54 to another of the dobby jacks d so that whenever the dobby jack 20d is shifted, the lever 49 is pivoted counterclockwise` Whenever this occurs, the connected needles are pulled out, away from the cards and cylinder7 and thus the selvage warp ends controlled thereby are raised.

The purpose of this new selvage motion is readily understood if it is kept in mind that this loom arrangement is utilized to weave a fabric in which certain picks are desired in the selvage and others to be omitted, and one in which there are no changes of warp threads after cer- As a result, the same card remains interposed l tain picks to bind the filling threads. In the prior jacquard arrangement, the'selvage motion requires a new card for each pick even though the main portion of the shed formation remained unchanged, However, it will be appreciated, as can be seen in Fig. 4, that by pulling certain of the needles 35a away from cylinder and cards when the latter are in an operative position to depress other needles, the selvage warp ends may be activated independently of the cards. Therefore, dilerent selvage shed formations may be drawn on successive picks without relation to the jacquard card interposed between the cylinder 3f and the'forwardends of the needles 35.

lt is to be understood of course, that other means apparent to one skilled in the art may be used to connect selected needles 35 with the dobby jack 20d and that the needles controlled thereby may be utilized to form other shed formations. Also, the number of needles that are activated may be widely varied in this manner if so desired, and in some complicated type weaves, it may be preferable to utilize two or more dobby jacks, each activating dierent groups of needles independently of the cards.

With reference to Figure l, each of the shuttle boxes 14 and 15 house a shuttle and each of the shuttles carry a bobbin on which a different kind of filling yarn is wound. The required shuttle (carrying the desired filling yarn) is propelled across the race plate 56 and through the shed formed by the warp ends, by raising or lowering the shuttle boxes 14 and 15 into alignment with the race plate 56. The mechanism for selectively moving the shuttle boxes 14 and 15 is commonly known as a dobby box motion and is well known to those familiar with the art. The box motion in turn is controlled by a convent-ional box chain which operates according to the same general principle as the dobby harness chain.

It will be appreciated that in the conventional bedspread loom, the selection of the shuttle boxes is controlled by the jacquard lines, which in turn are controlled by the needles and cards. The advantage of operating the box motion by the box chain, is illustrated by the following example. If on successive picks a repetition in the weaving pattern occurs, in the applicants new loom arrangement a new `card will not be required. However, where the shed formation remains unchanged, but a different type or color of lilling yarn is called for, extra cards would be required `in this new arrangement, if the box motion were controlled by the jacquard rather than by the independently -operated box chain.

Figure 5 discloses a diagrammatic sketch of a conventional Marseilles weave woven on a pick and pick type bedspread loom. It will be seen that the rst and fourth jacquard controlled ends are raised alternately every fourth pick, regardless of whether the putt, ligure or ground portions are being woven. As previously explained, this motion is carried out at the desired intervals by a conventional knot-board operated by -a complicated side cam motion. It will also be seen that in the conventional Marseilles weave disclosed in Figure 5, the rst and second boxes which house two shuttles carrying different kinds of lilling yarn, are changed on odd numbered picks; the rst box controlling the face and back filling operating for three picks followed by the second box controlling the stuffer filling, operating for one pick. Also as previously explained, this box sequence requires an inefficient, complicated pick and pick loom,'because it is the only loom in which a change in the boxes can be eected after one of the boxes has been in operation for an odd number of picks. Furthermore, whenever a repeat in the fabric occurs, as previously pointed out, a new 'cardmay still be required in the old loom arrangement, in order to control the interlacing of the -selvage warp ends unless a special auxiliary mechanism is added to the loom. It is thus apparent that initially a relatively large number of cards are required to weave this c0nvention-al Marseilles fabric, and this number is nearly doubledA because the loom is of a pick and pick type.

Figure 6 discloses a diagrammatic sketch showing the interlacing of the filling and warp ends in a typical Marseilles weave woven by my loom arrangement. It is to be understood of course, that a fabric of this type may be Woven in a great variety of patterns and designs and still be woven in accordance with the weaving principles next to be described. Furthermore, it is to be understood that the applicants loom arrangement can be used to Weave many other types of double or triple cloth fabrics, as well as single cloth fabrics with a wide variety of designs and colored patterns.

Referring to the ground weave illustrated in Figure 6, it will be seen that the weaving pattern forming this portion of the fabric is repeated every 12 picks. Further, it will be noted that this portion of the fabric is a single cloth, with all of the warp ends interlacing with at least one of the 12 fillings in each repeat of the weave.

In this new Weave, as in the conventional weave shown in Figure 5, the face picks indicated by black dots, and the backV picks indicated by hatched circles, are both formed of the same type of relatively light-weight yarn. The stufler picks indicated by circles, are formed of a relatively heavy-weight yarn. However, in the puff, iigure as well -as the ground weave portions of th-is new Marseilles type weave, the stuffer filling controlled by the second box, is changed only on even numbered picks; the iirst box being operated on the first 1-2 and 7-8 picks, and the second box on the v3-6 and 942 picks. As previously pointed out, this filling change sequence makes it possible to weave this fabric on a 2 x 1 box loom because the boxes controlling the different types of fillings need only be -changed when the shuttle comes to rest 4on one side of the loom and at the completion of two ormore even numbered picks. It will also be rappreciated that by using this same box sequence when weaving all portions of the fabric, a simplied dobby box chain arrangement, which was previously described, may be used when weaving all parts of this new Marseilles type fabric. f

With reference to the chart disclosed in Figure 7, the two files -of Xs in the rst -column entitled, Box Motion,7 indicate which of the two boxes is operated during one repeat (12 picks) of the Weave. The right-hand file of Xs indicates that the first box is operated on the 1-2 and 7-8 picks, and the left-hand file of Xs indicates that the second box is operated on the 3-6 and 9-12 picks. It is apparent that this is the same box sequence used in the new Marseilles type weave disclosed in Figure 6.

Still referring to Figure 7, the two les of Xs in the column entitled, Selvage, indicate on 4what picks the dobby jack 20d operates the selvage mechanism 48, as described in detail in connection with Figure l. The right-hand file of Xs indicates when the selvage mechanism lis operated. Thus, it can be seen from Figure 7 that the selvage mechanism 48 is operated on the l-3 and 7-9 picks. The left-hand iile of Xs indicates when a similar selvage mechanism (not shown), connected to the opposite side of the cloth, is operated.

The significance of this selvage motion may be appre-v ciatedby referring, for example to the ground weave portion of the fabric illustrated in Figure 6. Here it will beV seen-that the fillings on the 1-3 picks and vfillings on the .7-9 picks are interlaced with only the first and fourth jacquard controlled Warp` ends. Therefore, it is necessary, 4 aS was previously described, for Ythe ends of these sparsely interlaced fillings to be held firmly by ther selvage warp ends. In order that this may be done, the selvage shed formation must be changed on these picks, even though the same jacquard card remains interposed between the ends of the needles 35 and the card cylinder 33. Also it willbe notedthat on picks 1-2 and 7-8, when the-stuffer filling is inserted, that no Ished changes are shown in Figure 6 to bind the picks. These stutfer picks raised and pass under the filling.

the first and second picks, only the iirst jacquard controlled are ornittedfrom vthe selvage to' make it more uniform. The actual binding -of these picks is handled by a catch cord controlled in a conventional manner by hooks. The

hooks are permanently raised and lowered by the rocker arms of the jacquard head which alternate on every pick regardless of other motions carried out by the dobby and jacquard lines.

Referring to the -third column entitled, Cylinder Check in Figure 7, the Xs indicate when the dobby arm 20c of Figure 1, is moved, which as described in connection with Figure l, controls the advancement of the jacquard cards 34. Thus, it will be seen that on the 1-2, 6 8 and 12 picks, the same jacquard card remains interposed between -the needles 35 and the card cylinder 33.

The fourth column entitled Wire Harness, has two iiles of Xs. The left-hand iile of Xs indicates that the first harness Sti shown in Figure 1, which controls the second and fifth warp ends, is raised on the 5th, 6th and 11th picks. The right-hand file of Xs indicates that the second harness 31, which controls the third and sixth warp ends, is raised on the 5th, 10th and 12th picks. With reference to Figure 6, it will be seen that the interlacing sequence of the harness controlled warp ends is the rsame as -that indicated by the Xs in the fourth column of Figure 7.

With reference to the chart shown in Figure 8, the vertical column of numbers (l-l2) on the left-hand side of the chart, correspond with the l2 picks forming the ground weave portion of the fabric shown in Figure 6. The second vertical column of numbers indicates the jacquard card number called for on each pick; the same num ber being assigned to identical cards. It will be seen that the numbers range from 1-6, Iand at certain intervals the numbers are repeated on successive picks. For example, card #6 is called for on both the first and second picks. By referring to the column entitled, Cylinder Check, in` Figure 7, it will be seen that the jacquard card cylinder is not rotated `on the first and second picks, and thus the same jacquard card #6 is used over again. Therefore, it will be yappreciated that only six jacquard cards, rather than twelve cards are required for the twelve picks which make up one repeat of the weave of `the fabric.

It will be kept in mind that in a conventional jacquard loom, identical cards would be required whenever a repeat in the shed formation of the warp ends occurs. In this connection, it will be noted that 8 picks comprise one repeat of the ground weave portion of the conventional Marseilles fabric shown in Figure 5. In a conventional loom arrangement this would require, as previously explained, eight jacquard cards `to operate the jacquard controlled warp ends, even though a repeat in the shed formation occurs on the 2*5 and 6-8 picks.

It will be understood of course that the method and apparatus described in the preceding paragraphs for reducing the required number of jacquard cards may be applied whether ground, puff or figure, or combinations thereof fare being woven simultaneously across the width of the loom.

The two vertical columns of Xs in the chart shown in Figure 8, indicate the interlacing sequence of the first and fourth jacquard controlled warp ends, respectively, while weaving grcundportions of the fabric. Whenever an X appears in one of the columns, one of the jacquard controlled ends is raised and passes over the filling. Where no X appears, the jacquard controlled ends are not Thus, for example, on

ends are raised, and on the third pick only the fourth jacquard controlled ends are raised. 'In the fourth and tenth, neither of the jacquard controlled warp ends is raised.

With reference to Figure 6, it will be seen that the puffed portion of the fabric is a double cloth, having stuifer picks interposed therebetween which do not interlace with any of the warp ends. In this portiony of vthe fabric, the actual face of the puffed portion is formed by the inter-lacing of filling on the 4-6 and 10-12 picks with the 2-3 and 56 warp ends. These warp ends are raised and lowered by the harnesses 30 and 31, while at the same time the first and fourth warp ends are raised out of the path of the shuttle by the jacquard lines. The backing of the puffed portion of the fabric, as will be seen, is a loosely woven material, formed by the alternate interlacing of the first and fourth jacquard controlled ends with the filling on the third and ninth picks, respectively. lt will also be seen that one repeat of the puffed portion of this new Marseilles type fabric occurs on every 12 picks; the last two of the fourteen picks shown as puff being identical to the first two. The disclosure in Figure 6 shows that a transition from puff to figure stitches or back to ground is arranged to occur at two picks after a given repeat in order that the jacquard ends may become bound to the ground simultaneously. Thus a sharp break occurs in the puff portion of the Weave and as a result, the outlines of the puff portion are clearly defined.

With reference to the conventional Marseilles fabric shown in Figure 5, it will be noted that one repeat of this portion of the fabric occurs on every 8th pick and that the backing is formed by the alternate interlacing of the first and fourth jacquard controlled ends on the first and fifth picks, respectively. It is apparent therefore, that the backing of the old weave is a more closely woven material than the backing in the new Marseilles type weave because the interlacing of the filling and warp ends occurs every four picks, rather than once every six picks. Also it will be noted that the puffed portion of the conventional fabric is woven in the reverse order in respect to the new weave; i. e the actual face of the conventional weave is woven rightside up, while in the new Marseilles weave the actual face is formed beneath the backing. This same distinction holds true in regards to the ground and figure portions of the fabrics as well. This of course, has no bearing on the fundamental design or method of producing the new Marseilles type fabric. The object of inverting the weave is to reduce the lifting of the warp ends to a minimum, particularly when the puff portion is woven. The wire harness actually contains more warp ends than the jacquard harness in the above-described arrangement, hence, in the puff portion it would frequently be necessary to raise both wire harnesses simultaneously if the cloth were woven face up. With other types of designs, it may be desirable to reverse the process and weave the face of the cloth uppermost.

From the preceding paragraphs, in which the new Marseilles type fabric is described in detail, it is apparent that the weaving design of this new fabric, as well as any other fabric woven by this new loom arrangement, must be especially designed to comply with the operational limitations and advantages of this new loom arrangement. Furthermore, it will be appreciated that when designing a new weaving pattern, many interrelated problems must be considered. For example, in the puffed portion of the fabric, the over-all design pattern must be maintained, while at the same time the filling and warp ends making up the various layers of the fabric must be interlaced sufficiently so that the fabric will hold together and the various types of fillings will be maintained in the desired position. Another example of the many interrelated problems to be considered, is that the new weaving pattern must oe designed so that it can be woven on a 2 x l box loom rather than by a pick and pick loom, and still permit the formation of a wide variety of pattern designs. In addition to the above considerations, the interlacing sequence of the warp and filling ends must be such that the fabric will be able to withstand the wear and tear of normal usage.

It will be understood of course, that different types of looms, jacquard attachments and dobby heads may be utilized in the applicants new loom arrangement and that other weaving operations normally controlled by the jacquard attachment may be controlled by the dobby 8 head. In addition, it is to be understood that other types of fabric besides a Marseilles type weave may be woven by this new loom arrangement. Therefore, the form of the invention described above should be considered as illustrative and not as limiting the scope of the following claims.
