1 Claim. (Cl. 139-39) The present invention relates to pile fabrics, especially carpet and rugs, particularly of the type in which textured effects are achieved in the pile.

The present invention is a continuation in part of my copending applications Serial No. 167,534, filed `Tune 12, 1950, Afor Velvet or Tapestry Weave, Loom and Velvet or Tapestry Carpet Fabric, now Patent No. 2,754,850, Serial No. 191,830, tiled October 24, 1950 for Weaving Pile Fabric Having High and Low Loops, now Patent No. 2,709,460, and Serial No. 190,280 filed October 16, 1950, for Multiple Pile Staggered W-Weaving, now Patent No. 2,714,902, which prior applications are incorporated herein by reference.

The present application has been divided, and the subject matter relating to the fabric is embodied in application Serial No. 351,582, filed April 28, 1953, for Weaving Pile Carpet Having Textured Eiect.

A purpose of the present invention is to interweave two or more pile warps, weaving preferably on the velvet system, although permissibly according to the Wilton or brussels system, to raise the respective pile warps over diierent wires and to employ a succession of different wires producing a succession of different pile configurations varying in the dierence between high and low pile, wavy and straight pile, cut and uncut pile, and the like, for raising a particular pile warp in a given pattern area. Thus one pile warp may be raised successively over high and low wires, cutting and non-cutting wires, wavy and straight wires and variations and combinations thereof while another pile warp is raised intermediately to form transverse pile rows of a different character.

A further purpose is to intermingle pile warps of different colors or characters and desirably to make up each pile warp of numerous ends, each having a different color or character or made up of groups of different colors lor characters.

Further purposes appear in the specification and in the claim.

In the drawings I have chosen to illustrate several only of the numerous embodiments in which my invention may appear, selecting the forms shown from the standpoints of convenience in illustration, satisfactory operation and clear demonstration of the principles involved.

Figure l is a conventional warpwise diagram of a weave according to the invention with conventional showing of the wires.

Figures 2 to 36 inclusive are conventional crosssections showing portions of the wire sets which will be employed in different embodiments of the invention, these gures indicating the sequences of different wires of different characters. Where the wires are wavy wires it is assumed that the sections happen to be taken through the lowest points in the shed and show the highest points in the background.

In the drawings like numerals refer to like parts throughout.

In accordance with the present invention I increase the variants available to the designer in creating textured ice effects on warp pile fabrics, especially carpet and rugs, by permitting variations in the pile configurations of one pile warp which is interwoven with another pile warp, creating pile warps of different character. Thus, in accordance with one aspect of the invention, one pile warp creates successive different characters of pile, for example high and low pile, wavy and straight pile, cut and uncut pile or combinations thereof.

I also find that novel effects can `be obtained by securing contrasts between the rows of pile projections of the different pile warps or permissibly of the same pile warp interwoven with a different pile warp by weaving both of the contrasting rows of pile projections over wavy wires, but distinguishing the effects from the wavy pile projections in the different rows either of the different warps or of the same warp interwoven with the different warps. The contrast may, according to one plan, be obtained by using highest pile projections of different heights in the different rows of wavy pile projections. The lowest pile projections in the different rows will in one embodiment be of the same heights. In another ,embodiment the lowest pile projections are of different heights. In some cases the rows having the higher highest pile projections will have the higher lowest pile projections while in other embodiments the rows having the higher highest pile projections will have the lower lowest pile projections.

This feature can also be employed by making the highest pile projections in the different rows of the same height and accomplishing contrast by varying the heights of the lowest pile projections in the different rows.

Contrasting effects will also be obtained in some instances by using combinations of straight and wavy wires, suitably with differences in heights and cutting and noncutting character.

Special wire sets will be employed to achieve these results and due allowance will be made for the extent of pulldown of adjacent pile projections in withdrawing the wavy wires.

The invention will nd application in many cases to a plurality of pile warps which are interwoven and each of which has warpwise pile warp ends of different characters, suitably differing in color, twist, weight, density or construction, either as to individual ends or as to bands of ends of the same character, arranged side by side.

The effects obtained lby texturing may also be accented by shearing only the highest of the wavy pile projections and leaving the other pile projections unsheared.

While the invention may be employed in wilton and brussels carpet weaving it is believed to find its greatest application in velvet carpet, by which I mean to include tapestry carpet. In other words, in the preferred embodiment all of the ends of a particular pile warp will be raised over a particular wire to form one transverse row and all of the ends of another pile warp will be raised over another wire to form the next transverse row. vThe relation of the wires which form the pile for the dii-ferent warps in a given pattern area is important in the invention.-

While it is permissible to use 3, 4, 5 or more pile warps, the principle of the invention will readily be understood by considering weaves employing two pile warps.

Where wavy wires are used, the shape may be a sine or other wave, but it will preferably be a series of plateaus or llats of different heights, suitably three or more heights, with intermediate merging surfaces, suitably at gradual enough angles so that those facing toward the head of the wire can be pulled without tearing the loops (the angle should preferably be of ten to fifteen degrees to the major axis of the wire).

Figure l `shows a weave according to the invention. While this employs a single binder warp, it will be understood that two binder warps can be used if desired. The weave illustrates two pile warps 75 and 76 alternately raised over wires, and serving to illustrate that any desired plurality of pile warps can be used. Binder warp v84 is woven in opposition to stuier warp 91.

In the iirst step illustrated pile warp 75 is fully raised, pile warp 76 and stuier warp 91 are raised halfway, forming an upper shed and binder warp 84 is lowered forming a lower shed. A wire 96 is inserted in the upper shed and a shot of weft 97 is inserted in the lower shed.

In the next step, binder warp 84 is raised halfway and all other warps are lowered, forming a lower shed. A shot of weft 97 is inserted in the lower shed.

In the next step, pile warp 76 is fully raised, pile warp 75 is raised halfway and stuer warp 91 is raised halfway, forming an upper shed, and binder warp 84 is lowered forming a lower shed. A wire 98 is inserted in the upper shed and a shot of weft 97 is inserted in the lower shed.

The next step is a repetition of the second step. The weave then repeats.

It is important to note that wire 98 is different from wire 96, as later explained, so that pile projections of different characters are formed over the two wires of the wire set.

Figure 1 shows a velvet carpet using a staggered W-weave, as illustrative of the invention.

In Figures 2 to 36, in order to simplify the showing, I illustrate merely the diagrammatic form of the wires and the pile projections omitting the backing of the fabric. These are warpwise sections of the pile portions of the fabrics, the backings being as shown in Figure 1.

In some eases it is preferable to use wavy wires applied to both pile warps, thus producing high and low loops in the same transverse row and preferably on both warps in a given pattern area. Novel eiects may thus be produced by relations of the heights of the high portions of the wires and the heights of the low portions of the wires on the alternating wires, thus varying the relations of the highest and lowest pile projections to one another in the particular row and in reference to the alternate row. Where the adjoining wires on the same pile warp are wavy wires, the wavy wires will desirably be non-cutting.

Figure 2 shows wavy wire portions 103 on the tops of the wires 96 in the shed over which pile loops 100 are formed by pile warp 7S in a given pattern area and also on wires 98 over which pile loops 101 are formed by pile Warp 76 in the same pattern area.

In wires 96 and 98 of Figure 2 the highest wavy portions within the shed are of different heights while the lowest wavy portions are of the same height. In the particular pattern area pile warp 75 is raising loops over wires having the lower highest portions and the same height of lowest portions, while pile warp 76 is raising loops over wires having the higher highest pile portions and the same height of lowest portions on the transverse wlres.

In some cases as shown in Figure 3, the wavy wires 96 having the lower highest portions, over which in the particular pattern area pile warp 75 is raised to create loops 100, have the lower lowest portions, while pile wires 98 over which pile warp 76 s raised to form pile loops 101 in the particular pattern area have higher highest portions and lowest portions which are higher than the lowest portions of pile wires 96 and will in some cases be higher than the highest portions of pile wires 96.

In some cases both the heights of the lowest and highest portions of the wires raising one pile Warp will be between the heights of the highest and lowest portions of the wires raising the other pile warp. Thus in Figure 4 the heights of the highest and lowest portions within the shed of pile wires 96 over which pile warp 75 is raised in the pattern area to form pile loops 100 lie between the heights of the lowest and highest portions within the shed of pile wires 98, over which pile warp 76 is raised to form pile loops 101.

In some cases the heights of the respective highest portions of the wavy wires are the same and the heights of the lowest portions within the shed are different as shown in Figure 5. As here observed, wires 96, over which pile warp 75 is raised to form pile loops and wires 98 over which pile warp 76 is raised to form pile loops 101 have highest portions of the same height, but lthe lowest portions as shown are of different heights, being higher on wires 98 than on wires 96.

In some cases the heights of both highest and lowest portions on wires 96 and 98 are the same as shown in Figure 6.

In some cases one pile warp will be raised over straight non-cutting wires and the other pile warp will be raised over wavy non-cutting wires, as shown in Figures 7 to l0, inclusive'.

In Figure 7, wavy non-cutting wires 96 which form wavy pile loops by raising pile Warps 75 in the particular pattern area have highest portions of the same height as straight non-cutting wires 98 over which pile warp 76 is raised to form pile loops 101` As shown in Figure 8, in some cases the heights of the straight wires are between the heights of the highest and lowest portions in the shed of the wavy wires. Here wavy wires 96 raise pile warp 75 to form pile loops 100 and straight wires 98 in the same pattern area raise pile warp 76 to form pile loops 101, the height of the straight wires 98 being intermediate between the heights of the highest and lowest portions of wavy non-cutting wires 96.

In some cases, the straight wires are lower than the lowest portions in the shed on the wavy wires as shown in Figure 9 where wavy wires 96 raising pile warp 75 to form pile loops 100 have highest and lowest portions within the shed which are higher than the heights of straight non-cutting wires 98 which raise pile warp 76 to form pile loops 101. Y

Likewise in some cases the heights of the high and low portions of wavy pile wires 96 which raise pile warp 75 to form pile loops 100 in the particular pattern area are both lower than the heights of straight non-cutting wires 98 which raise pile warp 76 to form pile loops 101, as shown in Figure 10.

In some cases the straight wires interposed among the wavy wires may be cutting wires as shown in Figures ll to 14, inclusive. In Figure 1l, the wires 96 which raise pile warp 75 to form pile loops 100 are wavy wires whose highest portions within the shed are of the same height as straight cutting wires 98 having cutters 102 at the far end which raise pile warp 76 to form pile tufts 101. In Figure l2, the heights of the straight wires 98 are intermediate between the heights of the lowest and highest portions in the shed of the wavy non-cutting wires 96. In Figure 13, the heights of the highest'and lowest portions of the wavy noncutting wires 96 are greater than the heights of the straight cutting wires 98.

In Figure I4 the straight cutting wires 98 are higher than both the highest and lowest portions of the wavy non-cutting wires 96.

In accordance with 'the invention, the principles which have just been outlined will desirably be applied to vary the sequence of wires over which a particular pile warp is raised in a particular pattern area, and this will preferably be done to the wires over which both pile warps are raised in that pattern area. To simplify the showing, I illustrate in Figures l5 to 35 inclusive, wires 96 shown generally in dot-and-dash lines to indicate that they are wires of any of the characters of Figures 2 to 35 inclusive, alternating with wires 98 which showrthe special features of the invention and are in some cases designated 98'and 98 to indicate that variations exist. In describing these figures, pile projections 100 of pile warp 75 raised over wires 96 are not being separately described, it being understood that these will be of any of the characters herein referred to and conforming to the wires over which pile warp 75 is raised.

In Figure 15, pile warp 76 is raised to form pile loops 101 over non-cutting wavy wires 98 and 98 alternating with the wires 96, the wavy wires 9S and 98 having highest portions within the shed which are of different heights (higher on wires 98') and lowest portions within the shed which are of the same height.

As shown in Figure 16, wavy non-cutting wires 98 have highest portions within the shed which are intermediate in height between the highest and lowest portions within the shed of wavy non-cutting wires 98', while the lowest p0rtions of wires 98 are lower than the lowest portions of wires 98'.

Figure 17 is the same except that wavy non-cutting wires 93 have highest and lowest portions within the shed which are intermediate between the heights of the highest and lowest portions within the shed of wavy non-cutting wires 98.

In Figure 18, wavy non-cutting wires 98 and 98 over which pile warp 76 is raised to form pile loops 101 have highest portions within the shed of the same height but the lowest portions of wires 98 are higher than those on wires 98.

As shown in Figure 19, wires 98 are low straight round or non-cutting wires and wires 98 over which pile warp 76 is also raised are high straight round or non-cutting wires.

Similarly as shown in Figure 20, wires 98 over which pile warp 76 is raised to form pile tufts 101 are in this case low straight wires having cutters at the far ends (opposite the head) while pile warps 98 are high straight wires having cutters 102 at the ends remote from the heads. Either the low or the high wire may be non-cutting as shown in Figures 21 and 22. In Figure 21 wires 98 are low straight non-cutting wires and wires 98 are high straight wires having cutters at the ends remote from the heads. In Figure 22 the low straight cutting wires are 98 and the high straight non-cutting wires are 98.

The wires 9S and 98 may be straight cutting and noncutting wires of the same heights as shown in Figure 23.

Where desired, the wires 98 will include, alternating with straight wires, any of the characters of wavy wires described. In Figure 24, wires 9a', are low straight round or non-cutting wires raising pile warp 76, wires 98 are non-cutting wavy wires of any suitable character which alternate throughout the wires raising pile warp 76 in any pattern area and wires 982 are high straight round or noncutting wires. Thus pile warp '76 is raised first over a low straight round wire, then over a wavy wire bearing any of the relations herein specied to the straight wires, then over a high straight round wire bearing any of the relations herein specied to the wavy wire and then again over a wavy wire of any of the types herein referred to.

In the case as shown in Figure 25, the wavy wire 98 will where desired be provided with a cutter at the far end and the wires 93 between each pair of wavy wires will suitably have ,the sarne height, which is the same as fthe lowest portions on the wavy wires. In Figure 26, the

straight non-cutting wires over which pile warp 76 is raised in a particular pattern area suitably consists of a low straight non-cutting wire 93 and a high straight noncutting wire 982 with a wavy wire 9 8 having a cutter at the far end interposed between the two straight wires 98 and 982. The low straight wire has the same height as the lowest portions on the wavy wire.

In some cases the wires over which pile warp 76 is raised will all be wavy wires bearing a special relation between certain wires. As shown in Figures 27 to 31, wires 96 over which pile warp 75 is raised constitute any of the wire combinations herein described. The wires over which pile warp 76 is raised to form pile loops 101 in the particular pattern area comprise wires 98, wires 98 and wires 982, there being one wire 98 between the wires 98 and 982. All of these wires are wavy,`non cutting wires. Wires 98 are wavy wires having any of the relations of heights of highest portions and lowest portions to wires 9S and 982 herein referred to, but wires 9S and 932 bear a special relation in Figures 27 to 3l.

In Figure 27 thev highest portions within the shed of non-cutting wavy wires 98 and 982 have diterent heights whereas the lowest portions have the same height. In Figure 2S the highest portions within the shed of wavy non-cutting wires 9S have a height between that of the highest and lowest portions within the shed of wavy noncutting pile wires 982, while the lowest portions within the shed of pile wires 9S have a height lower than the lowest portions within the shed of wavy pile wires 9.32. In Figure 29 pile wires 9S have highest and `lowest p0rtions within the shed whose height is intermediate between the heights of the highest and lowest portions within the shed of pile wires 982.

Figure 30 shows pile wires 98 and 932 whose highest portions within the shed are of the same height and in which the pile wires 932 have higher lowest portions than the pile wires 98.

In Figure 31 wavy pile wires 98 and 932 have the same heights for both the highest and the lowest portions within the sir-ed.

It will be evident that in some cases straight and wavy wires will desirably alternate as applied to the same warp as shown in Figures 32 to 35. In Figure 32 ypile warp 76 is raised alternately over straight Vnon-cutting pile wire 98 and wavy non-cutting pile wire 98 having the highest portions within the shed of the same height as straight wire 98.

In Figure 33 pile warp 76 is raised alternately over straight non-cutting pile wire 98 and wavy non-cutting pile wire 93 having its highest portions within the shed higher than straight wire 98 and its lowest portions within the shed lower than straight wire V98.

In Figure 34 wavy non-cutting pile wires 98' alternate in raising pile warp 76 with straight non-cutting pile wires 9S, straight wires 98 being lower than the lowest portions within the shed of wavy wires 98. On the other hand in Figure 35 straight non-cutting pile wires 98 are higher than the highest portions within the shed of wavy pile wire 98'.

Figure 36 shows a specic 'example in which pile warp '76 is always raised over wavy pile wire 98, while pile warp 75 is raised alternately over low straight cutting pile wire 96 and high straight non-cutting pile wire .96 which is suitably of the saine height as the highest portions on the wavy wires 9S, while pile wire 96 is suitably of a height intermediate between the highest and lowest portions on the wavy wires.

The wavy wires may have any of the characters well known in the art as suggested by Rodier French Patent 451,065 or Jackson U. S. Patent No. 2,516,465. The high and low points on successive wavy wires will, of course, be displaced at diierent positions laterally to achieve a pattern eect as shown in Deperchin Belgian Patent 250,673.

Where two wavy wires are to be used in association, the heights of the high and low portions of the pile loops produced in accordance with the invention may bear any of the wide variety 'of relationships to one another as shown in the table. Y v

The next four columns give the actual heights of pile wire A and pile wire B in thousandths of an inch and the last four columns give the heights of the final pile projections in two adjoining rows produced by the wires of the particular examples. Thus it will be seen that for any particular height of the high pile projections in the row having the higher highest pile projec-v tion, the highest pile projections in the next row will be the same height or lower. The lowest pile projections in the first row will be lower than, the same height as, or higher than the highest pile projections in the next row and may be lower than, the same height as, or higher than the lowest pile projections in the next row.

Thus the highest pile projections in the two rows may be of the same height or different heights and the lowest pile projections in the row having the higher highest pile projections may be lower, the same height or higher than the highest pile projections and aiso the lowest pile projections in the row having the lower highest pile projections. This combination of heights of wavy pile projections in adjacent rows gives many novel effects. Likewise with the highest pile projections of the same height, novel effects may be obtained by using lowest pile projections of different heights in the different rows.

These features may be applied in adjacent rows of wavy pile projections of different warps or in adjacent rows of pile projections of the same warp alternating with pile projections of a different warp as already explained.

It will be understood that :the principles of the invention may be applied with pile warps which are of the. same color throughout an individual pile warp, or with pile warps 1in which the individual ends or groups of ends are of different colors. Likewise the principles of the invention may be applied with pile warps whose ends are of different characters other than color, such as different twists, different materials, diiierent weights, or different constructions.

It will be evident that for best results the slope of the inclined portion of the wavy Wire on the side toward the head should not exceed approximately to the major axis of the wire. The details of this form no part of the present inventio-n and are disclosed in my eopending application Serial No. 191,830.

The principles of the invention may be applied with variations in thread-in. in accordance with the disclosure of my copending application Ser-iai No. 190,280.

It will be understood that in designing a pattern, where the pile warps are 'to be taken from beams, the pattern may where desired be compensating, that is, the .total height of pile on any one pile warp end in the pile repeat should equal the total height of the pile on any other pile warp end and at any other dent. Of course it will be understood that in case :the pile warp ends are distributed from spools or otherwise individually fed, it is not desirable to employ a compensating pattern.

By the invention it is possible to secure a wide variety of interesting and attractive effects and .to design carpets and other fabrics to blend effectively with other furniture and decorating plans.

In rthe invention a standard carpet loom such as the Crompton and Knowles or Dobcross will desirably be used, employing a standard wire motion which need only differ in the character of the wires making up the wire set.

It will be eviden-t that in accordance with one aspect of the invention the sequence of wires in Ithe w-ire set will be .a non-cutting wavy wire, a relatively high noncirtting straight wire, a non-cutting wavy wire and a relatively low non-cutting straight wire.

It will be also evident ythat according to another aspect of the invention the sequence of wires in the wire set will be a non-cutting wavy wire, a relatively low cutting straight wire, a non-cutting wavy wire and a relatively high non-cutting straight wire.

it will further be evident that where it is desired to employ the same character of wire `to raise the same pile warp throughout the fabric, I will preferably use a wire repeat throughout the wire set which is an odd number where the number of different pile warps is odd and an even number where the number of pile warps is even, whereby wire of a given kind will operate on the same pile Warp throughout.

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 process, structure and fabric shown, and I, therefore, claim all such insofar as ,they fall within the reasonable spirit and scope of my claim.

Having thus described uny invention I claim as new and desire to secure by Letters Patent:

The process of weaving a pile fabric to produce colored eiects without using a jacquard, using a pile warp set A of one color, a pile warp set B of another color, stuier warp ends, binder warp ends and wefts, which comprises fully raising all of the ends of pile warp 'set A over a first pile wire of a first wire set, raising all of the ends of pile Warp set B half Way, raising the stuffer warp ends half way yand lowering the binder warp ends, thus forming an upper shed and a lower shed, inserting a wire of the first pile wire set in the upper shed, inserting a shot of weft in the lower shed, next raising the binder warp ends half way and lowering all other ends, thus forming a lower shed, inserting a shot of weft in the lower shed, next fully raising all of the ends of pile warp set B, raising all of the ends of pile warp set A half way, raising the stutter warp ends half way and lowering the binder warp ends, thus forming an upper shed and a lower shed, inserting ya wire of the second pile wire set in the upper shed, inserting a shot of weft in the lower shed, next raising the binder warp ends half way, lowering all other ends, thus forming a lower shed, inserting a shot of weft in the lower shed, next fully raising all of the ends of pile warp set A, raising all of the ends of pile warp set B Ihalf way, raising the stutter warp ends half way, lowering the binder warp ends, thus forming an upper shed and `a lower shed, inserting a wire of the first pile wire set in the upper shed, inserting a shot of weft in the lower shed, next raising the binder warp ends half way, lowering all other ends, thus forming a lower shed, inserting a shot of weft in the lower shed, next fully raising all ends of pile warp set B, raising all ends of pile warp set A half way, raising stuer Warp ends half way, lowering the binder Warp ends, thus forming an upper shed and a lower shed, inserting a wire of the second pile wire set inthe upper shed, inserting a shot of weft in the lower shed, next raising the binder Warp ends half way, lowering all other ends, thus forming a 10 Y lowershed, inserting a shot of weft in the lower shed, and successively changing the character of the wires of the second pile wire set to create pattern areas in which pile warp A is raised to the higher level in the face of the pile, land areas in which pile warp B is' raised to the higher level in the face of the pile, the particular character of wire raising pile warp B being different in different pattern areas.
