FILE JUMP FABRIC Original Filed March 31. 1954 8 Sheets-Sheet 8 COURSES A B C D W/RES United States Patent PILE JUMP FABRIC Divided and this application March 9, 1955, Serial No. 493,256

11 Claims. (Cl. 139-406) The present invention relates to pile fabrics especially of the character of carpets and rugs, and is applicable to velvet, tapestry, Wilton and Brussels weaving.

. This application is a division of copending application Serial No. 420,088, filed March 31, 1954, for Pile Jump Weaving, relating to the method and apparatus.

A purpose of the invention is to provide in addition to the normal pile a jump pile which changes its lateral position either between two anchorages of a pile projection or at the point at which it is anchored in the backing of the weave, and forms a float or a diagonal pile projection.

A further purpose is to provide jump pile projections in addition to normal pile projections in the same transverse row of pile projections and to shift the lateral position of the jump pile projections at intervals along the fabric as a pattern may require, forming floats or diagonal pile projections.

A further purpose is to insert a jump pile Warp .in front of the reed and to move the jump pile Warp heddle out of the way of the reed when the reed is beating up a weft or a Weft and wire, and to move the jump pile warp laterally at intervals so that jump pile ends will appear in different courses.

A further purpose is to introduce the jump pile projections by a jump heddle moved downwardly from above adjacent to an open top reed.

A further purpose is to employ normal weaving of anormal pile and to superimpose on it a jump pile or a plurality of jump piles which are laterally manipulated as well as vertically manipulated in weaving.

A further purpose is to bind the jump pile behind back wefts while binding the normal pile behind front we'fts.

A further purpose is to bind both the jump pile and the normal pile behind front wefts.

A further purpose is to employ a plurality of jump piles and to move them laterally at different positions,

to diflerent distances and desirably in some cases in op position to one another, forming floats or diagonal pile.

A further purpose is to form high floats and low :flo'ats as desired by jump pile and where desired also to reject the .jump pile in the back of the fabric.

A further purpose is 'to employ wires of any suitable character for raising thenorrnal pile and the'jur'np pile, including straight non-cutting wires, straight cutting wires, non-cutting wires having high and low portions along their lengths within the shed, "cutting wires having high and low portions 'along'their-lengtlis'within the shed and flag wires (having high portions beyond the shed) any desired combinations alternating or interspersed with one another, and with other wires where desired.

Further purposes appear in the specification and in the claims.

Figures 13 to 17 are fragmentary diagrammatic elevations of-the ends remote from the heads of wires accord-- ing to the invention, showing at the right extreme ends of the 'wires 'beyond the shed and, at the left a portion of each wire which is inside the shed.

In the Weaving of pile fabrics such as carpets and rugs on the velvet, tapestry, Wilton or Brussels systems, the pile warp ends are raised in the pile over wires,'being bound behind wefts at the beginning and ending of each pile projection. The individual pile warp ends retain the same relation to other warp ends throughout the length of the fabric, and never leave the courses (lateral positions determined by dents of the reed) in which they are woven.

The present invention is designed to obtain novelty effects and enhance the appearance of the pattern, and also to permit more elaborate patterns without complication in the weaving. In accordance with the invention pile warp ends are employed which supplement the pile warps ordinarily used, or the weaving with the ordinary pile warps is modified, to permit the movement of float .ends laterally so that they will be woven in different dents at diiferent "longitudinal positions. Thus these jump pile warps which move laterally can make the individual pile projection have/anchorages at the two ends in different dents, "or can move from one dent to another .at aposition at which the pile warp is bound "behind a weft. "In

this way his possible' tomake a particular-group of jump introduced in front ;0f the reed, preferably by a jump heddle which moves down and \up -as required, moves outof the way when thesreed itnust beat :up :a'weft or a wire,

and moves laterally to shift the position of the jump 3 pile warp. The jump pile heddle may as desired be wholly independent of the reed, or may be mounted on the reed. In this form it is quite proper to use a reed which is closed at the top.

In another form, a jump pile warp heddle or heddles are used which are located between the normal heddles and the reed, and the top of the reed is open. At a position in the weaving between any two steps, the jump pile warp heddle or heddles are raised above the reed and moved laterally and then lowered to insert the ends in different dents. The yarn is fed in downwardly to the jump pile heddles in front of the other heddles.

In accordance with the invention the jump pile warp can be anchored in the weave behind backwefts or face wefts, and can appear in the pile in every transverse row, alternate transverse rows or widely spaced transversed rows.

Where a plurality of jump pile heddles are used, the lateral movement of the jump pile warps may take place at different times, to difierent distances, and desirably with opposite movements.

The jump pile warps may also appear in high and in low floats, and the jump pile warp or warps can also be rejected as desired.

Where desired the jump pile warps can form the entire pile instead of merely making an auxiliary pile.

The jump pile warp can be controlled in its lateral movement by a jacquard mechanism, or any other suitable pattern control. One mechanism suitable for manipulating the jump pile heddle is an indexing shaft controlled by a dobby chain.

The invention is applicable to velvet, tapestry, Wilton and Brussels carpet weaving, and in any desired row the pile may be cut, uncut, uniform in height, high and low, or of several different heights as desired.

In order to illustrate the invention, I show primarily velvet carpet weaves, although it will be understood that the pile warp ends either of the normal pile or the jump pile or both will where desired be selectively raised by a pattern control such as a jacquard.

Jump pile warps forming floats are not: to be confused with lappet warps, which move laterally underneath the backing of the fabric and rise throughthe backing at intervals to form tufts on the face of the fabric. Strong, Fabric Structure (Chemical Publishing Co., 1947), 200 to 203.

In the form of Figure 1, the jump pile warp is introduced in front of the reed (between the reed and the fell), and is employed along with a normal pile warp, and in association with two binder warps and a stufier warp.

A normal pile warp 60 is shown, along with a binder warp 66 woven in opposition to a binder warp 71 and a stuffer warp 73, along with upper or face wefts 81 and lower or back wefts 84. A jump pile warp is provided at 77 which is suitably manipulated up and down and laterally, by a jump pile heddle described more in detail in my copending application. When raised the jump pile heddle can shift laterally above the other warp ends and when lowered it can move down among the other warp ends. The jump pile warp can have ends in each course or if desired may have ends in certain courses, omitting ends in other courses.

In the first step of the weave as shown in Figure 1,

. a lower shed is formed by raising binder warp 66 halfway and lowering normal pile warp 60, jump pile warp 77, binder warp 71 and stufter warp 73 and inserting a shot of weft in the lower shed.

In the next step of Figure 1, the jump pile warp heddle is raised so that the lower end of the jump pile warp heddle is above the top of the reed, and the jump pile warp passes under the weft 81 and then up in front of the reed. The reed then moves toward the fell to beat up the weft as in normal practice. According to thepattern demand as later described, the jump pile heddle moves laterally at a suitable step in the weave and this may be '4 immediately after the second step and before the third step or it may be after the third step and before the next step.

Between the second and third steps the jump pile warp heddle remains raised and a new shed is formed. In this position, the normal pile warp 60 is fully raised, the stufier warp 73 and binder warp 66 are raised halfway, forming an-upper shed. Binder warp 71 is lowered forming a lower shed. The jump pile warp 77 is fully raised and a wire 83 is inserted in the upper shed, and a weft 84 is inserted in the lower shed. The reed then beats up the weft and the wire, since the jump pile warp heddle is out of the way.

The completed weave of Figure 1 illustrates normal pile projections 85 and jump pile projections at 86 bound behind adjoining front wefts. It will be understood, however, that the jump pile projections, at least in some instances, move laterally from one course to another hetween the point of bind behind one binding weft and 77 is down, binder warp 66 raised halfway, binder warp fer warp 73 are raised halfway and binder warp 71 is- 71 lowered, and stutter warp 73 lowered. A shot of weft 81 is taken in the lower shed.

In the next step, the jump pile warp is moved up to a position above the fell and the reed can beat up the weft without striking the jump pile warp heddle. Between the next step and the following step, the jump pile warp will move laterally as the pattern requires to place the jump pile warp ends in different courses. The jump pile warp is held in upper position, while binder warp 66 and stuffully lowered forming a lower shed. A wire 83 is inserted in the upper shed and a shot of weft 84 is inserted in the lower shed. Between the next step and the first step of the following cycle the binder warps are reversed.

In Figure 2 the only pile projections are jump pile projections 86 but they are shifted as desired to different courses as the pattern may require and the multiplicity of these ends collaborate by laterally shifting to produce the pattern change.

In some cases it is desirable to put in more than two jump pile warps in front of the reed. A weave of this kind is shown in Figure 3. Two jump pile warps 77 and 77 are illustrated in front of the reed. Otherwise this weave can be like Figure 2. Between the second and the third steps the jump pile warps may move laterally as required, and it will be understood that the two jump pile warps usually will not move in the same way, the respective movements being two different distances in the same direction or opposite as desired. Thus in Figure 3 there are jump pile projections 86 and 86' each of which suitably originates and ends in a different course, and the jump pile projections 86 move laterally in different directions or different distances from the jump pile projections 86'.

In the descriptiongiven thus far, the jump pile ends have been put in in front of the reed, but it will be understood that they can be put in behind the reed providing an open type reed is used.

In Figure 4, I illustrate a normal pile warp 60, a second normal pile warp 60, a jump pile warp 77 fed directly downwardly behind the reed, stutter warp 73, binder warp 66 and binder warp 71.

It is immaterial from the standpoint of the present invention whether a single binder warp or a pair of binder warps is used and for convenience I show a pair of binder asaepeit The jump .pile warp ends are raised, shifted laterally from dent to dent and then lowered in difierent dents as required.

In the first step, with the jump pile warp fully raised, although still below the top of the reed, and normal pile warp fully raised, binder warp 71 is raised halfway forming an upper shed, and all other warps, that is, rejected pile warp 60', stufier warp 73 and binder 'warp -66 are lowered, forming a lower shed. Wire 83 is inserted in the upper shed and a shot of weft 84 is inserted in the lower shed. The shot of weft is here a face weft since it is in front of the stutfer'warp.

If desired the lateral shifting of the jump pile warp can take place between the first and the second step by raising the jump pile warp heddle above the reed, moving it laterally and reinserting it in the reed at a different position. It is preferred, however, to employ this feature at a later stage in the cycle as later explained.

In the second step binder warp 66 is fully lowered, and in this particular weave jump pile warp '77 is also fully lowered, and all other warps are raised halfway, forming a lower shed. A shot of weft 81 is inserted in the lower shed in this instance forming a back weft.

Immediately after the second step in the preferred embodiment, the jump pile warp is raised above the top of "the reed, moved laterally and reinserted below the reed. The number of dents or courses of lateral movement will preferably not exceed 4 at any one lo'om cycle, and in many cases a jump or movement of 'one or two dents laterally at any one loom cycle will be entirely satisfactory. In some cases a lateral movement of more than 4 dents will be used. This movement laterally takes place before the jump pile warp is raised over themext wire in this form (and thus is buried in the back of the fabric) and will not show by angular position of the pile projections as it would in case this was accomplished after the jump pile warp had been raised over the wire but before it was anchored behind the following weft.

:In the next step, normal pile warp 60 is fully raised and jump pile warp 77 is fully raised but still low enough so that the jump pile warp ends are in the reed. Binder warp 66 is raised halfway and another warps are lowered, forming a lower and an upper shed respectively. A'wire 83 is inserted in the upper shed and a shot of face weft 84 is inserted in the lower shed.

In the next step, binder warp 71 is lowered, jump pile warp 77 is also lowered, and all other warps are raised, forming a lower shed into which back weft 81 is inserted.

If desired the jump pile warp may be raised above the top of the open reed, moved laterally and reinserted in the reed at a different lateral position between the third step and the fourth step, in which case there will be a tendency to produce a diagonal :pi-le projection of the jump pile warp, or it may be raised, moved laterally and reinserted between the fourth step and the first step of the next cycle, in which case the lateral movement will be buried in the back of the fabric, but the jumpipile warp will appear in a different course or dent position. Thus the final result as shown in Figures 4 and 4a is to produce alternate rows of normal pile projections 85 in one transverse row and of normal pile projections 85 in the next transverse row, with the jump pile warp ends woven behind back weft 81 and appearing over the wire in each row. However, a particular jump pile warp will appear as best seen in Figure 4a in course A in the first row, in course B in the second row, in course C in the third row and in course D in the fourth row, the lateral movement being determined in direction and in extent by the .pattern. It will be evident that this is only one of a multiplicity of jump pile ends that are moving together.

While in Figure 22 the jump pile projections appear in each transverse row, they may instead appear in alternate transverse rows and be bound behind front wefts instead of back wefts as shown in Figures 5 and 5a. In this form there are jump pile projections '86 raised with pile projections in alternate transverse pile rows, but the particular sjumppile warp end-shown in Figures 5 and 5a appears successively in courses A, B and "C, as shown. It will be understood that with the thread-in used the jump pile warp ends need not appear in every dent, orcourse and if desired ithey'may employ multiple ends in "a particular dent or 'in certain dents. Likewise the thread in of the normal pile warp ends or of th'e jump pile warp ends or both mayinclude the use of ends-of successively different colors as the pattern dictates so that variations-in pattern effects can be obtained by leaving pile warp ends out of particular dents, placing mutiple pile warp ends in certain dents and fewer or no ends in other dents, and changing the color or material of the ends between'different dents.

The invention is also applicable to weaves in which there are a plurality of jump "pile warps as shown in Figures '6 and 6a, operated by a plurality of jump pile warp heddles introduced behind an open reed, which, except for the use of multiple jump pile warps, follow Figure 4. It will be understood that the jump pile warps 77 and 77 can be woven together, but with different lateral positions, or can be woven oppositely or differently.

Figure 6 shows the result of raising the jump pile warps with alternate lnormal pile warps,-shifting the jump pile ends into different dents as indicated by the letters A and B at different transverse rows to indicate the dents occupied by :the jump pile warps.

The lateral manipulation will vary widely with'the pattern, Figure 7 showing dents or courses 1 13 to 1 16'and face wefts 84, 84, 84 etc. The normal pile warp ends, binder warp ends, and stuffer warp ends are omitted. Thus the jump pile warp end of warp 77 which is shown in Figure 7 is in dent 113 between the wefts 84 and 84', moves to dent 114 between wefts 84 and 84 remains in dent 114 until in a position between weft 84 and 8 1- then moves to dent 115. On the other hand the particular end of jump pile warp 77" shown remains in dent 113 until, in the position between weft 84 and "84 it jumps laterally to dent 116 where it remains for several cycles. Other ends of each jump pile warp behave similarly. As explained it is a matter of pattern and weave design whether the jump is to take place before the particular jump pile warp is raised in the pile or after it has been raised over the wire and before it is anchored "behind the next weft, the difference being primarily that the pile projection will be diagonal in the latter case a'nd'not in the former case. The jump pile warp end in the particular dent will normaly be threaded-in beside the normal pile warp'end.

in some cases it will be desirable to manipulate the jump heddles in opposition laterally as shown in Figure 8. Here the jump pile warp 77 of which one end is shown, is in dent 113 and moves to *dent 114 between face weft positions 84 and 84, and remains there until between face weft positions 84 and 84 it moves back to dent 113. Likewise the jump pile "warp 77' of which one end is shown, .is in dent 114 and moves to dent 113 between face wefts 84 and '84", and then moves to dent 114 between face wefts 84 'and 84 Other ends of each jump pile warp behave similarly.

The invention :is applicable to high and low floats. In Figures 9 and 9a at least some of the ends 'of'jump pile warp 77 form high floats '1 17 over two wires, being bound behind face wefts on either side, while at least someof the ends of the jump pile warp 77 in succeeding rows form high floats 118 over two wires, bound behind face wefts at the sides. As indicated by the letters A and B, the particular end of jump pile warp 77 'shown is in dent -'B-'over the left hand wire, and indent A over the third and fourth wires, while the particular end of jump pile warp 77 shown is in dent A over the second and third wires and will be indent B 'overthe fifth wire (notsh'own), counting from theleft'ineach'case.

The invention is equally applicable to low floats, in which the float passes over one wire and between the face weft and the next wire as in Figures 10 and 10a. In this form only one jump pile warp is shown which is at dent A where it rides over the wire and at dent B where it travels between the wire and the face weft.

In some cases the jump pile warp will be wholly rejected and this is shown at 120 in Figures 11 and 11a. Unlike the usual rejected warp, however, the jump pile warp ends shown travel from dent A to dent B in weaving from left to right. It will, of course, be understood that it can move considerable distances laterally in the back of the fabric where it is rejected at 120 moving in jumps of l, 2 or 3 or more dents preferably at a given weft position.

Where desired all of the pile warps may be jump pile warps where the jump pile warps is introduced behind an open reed as shown in Figures 12 and 12a. This corresponds in general to Figure 5, omitting any separate normal pile warp and raising the piles alternately in alternate face weft positions over wires. Unlike the usual weaving procedures, however, the end shown of jump pile warp 77 is in dent A at the fifth wire, while the end shown of jump pile warp 77' is in dent A at the second wire and in dent B at the fourth wire. Thus in effect the jump pile warps move laterally through some predetermined pattern sequence which may be a criss-cross, a zigzag, an oval, a diamond or the like, and are capable of creating novel effects without a jacquard raising the pile ends or supplementing a jacquard, especially where different ends of a particular pile are of different colors at different lateral positions across the pile Warp.

'No attempt has been made in the present invention to illustrate all the possible wire combinations and embodiments which Will be employed in particular cases, it being suflicient merely to indicate different types of wires which will be used either uniformly or in various combinations or sequences. Figure 13 illustrates a straight non-cutting wire 83', Figure 14 illustrates a straight cutting wire 83 Figure 15 illustrates the noncutting wavy wire 83 having high and low portions along its top Within the shed, Figure 16 illustrates a cutting wavy wire 83 having high and low portions along its top within the shed and a cutter beyond the shed and Figure 17 illustrates a flag wire 83 which is permissibly straight within the shed but has a high flag portion beyond the shed. The form of Wire shown is noncutting though it will be understood that cutting flag wires can also be used.

The invention finds its widest application in carpets and rugs at the present time but it will be understood that it is also applicable to other fabrics such as upholstery fabrics and the like.

In view of my invention and disclosure variations and modifications to meet individual whim or particular need will doubtless become evident to others: skilled in the art, to obtain all or part of the benefits of my invention without copying the method and apparatus shown, and I, therefore, claim all such insofar as they fall within the reasonable spirit and scope of my claims.
