l 'Claiin. (Cl; 139-406 The present invention relates to pile fabrics of the character of carpets and rugs.

This application is a division of copending application Serial No. 338,694, filed February 25, 1953, now Patent No. 2,714,400, for Weaving With Wire Variations.

A purpose of the invention is to increase the production of carpets and rugs by carpet looms.

A further purpose is to permit weaving pile of different characters with pattern change using a jacquard mechanism, but employing only a single pile frame.

A further purpose is to insert wires alternately from opposite sides, to put in a wire with every shot of weft, and to selectively raise pile warp ends over wires of one character or wires of another character, floating the ends at the back of the fabric at points of pattern change.

A further purpose is to economize on material by reducing the need for wefts.

Further purposes appear in the specification and in the claim.

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

Figures 1 and 2 are warpwise conventional weave diagrams showing the same wefts at different positions weftwise of the fabric which correspond to different pattern areas.

Figure 3 is a diagrammatic top wires.

Figure 4 is a view corresponding to Figure 1 showing a variation.

Figures 5 and 6 are photographic views showing the faces of fabrics in accordance with the invention.

In accordance with the invention, at weft position 20, pile warp ends 21 selected by a jacquard or other pattern control are fully raised (Figure 1), while at another pattern area weftwise of the fabric pile warp ends 21 are lowered (Figure 2) by the jacquard. Binder warp 22 is raised half way, binder warp 23 is lowered and stutter warp 24 is raised half way. Thus an upper shed is formed in which a wire 25 of a first set is inserted, and a lower shed is formed in which weft 20 is inserted.

In the next step, as seen in Figure 1, pile warp ends 21 are lowered by the jacquard mechanism, and at another position weftwise as seen in Figure 2, pile warp ends 21' are fully raised. Binder warp 23 is raised half way and binder warp 22 and stutter warp 24 are lowered. Wire 26 of a second set is inserted in the upper shed and weft 20 is inserted in the lower shed.

While the invention can be applied with wires 25 and 26 of similar character, it will normally be very desirable to use wires of different characters in the different sets, for example one cutting and the other non-cutting, one high and the other low, one straight and the other wavy (varying in height along its length within the shed) or one of any of those characters and the other having a flag on the end beyond the shed.

So far we note that'in the different pattern areas the pilewarp ends 21 are'forming-pile of one character over wires 25 and the pile warp ends'2'1" are forming pile of a different character over wires 26. Now pattern change occurs under the" action of the jaequard or other pattern control. In the next step in both pattern areas pile warp ends 21 and 21 are both fully down, while the binder warps and stuffer warp reverse. Wire 26 inserted at this point has no function, in these pattern areas, although in some third pattern areas spaced weftwise from these, pile warp ends 21 or 21' may be raised over it as dictated by the jacquard. The effect is to cause a float 27 behind weft 20 at the back of the fabric of pile warp ends 21.

At the next step pile warp ends 21 are now fully raised, but a pattern change is taking place in pile warp ends 21 and they are fully lowered as shown in Figure l. The binder warps and stuffer warps reverse and wire 25 of the first set is inserted. Now we note in Figure 2 that whereas pile warp ends 21 were formerly over wire 26, they now appear over wire 25. Weft 20 is inserted in the lower shed and in Figure 1 pile warp ends 21 form a float 27 at the back of the fabric.

At the next step as seen in Figure 1 pile warp ends 21 are fully raised over wire 26 of the second set, and in Figure 2 pile warp ends 21 are fully lowered and the binder and stuffer warps have reversed. Wire 26 is inserted in the upper shed and weft 20 is inserted in the lower shed. There is now a complete pattern change in these two areas as pile warp ends 21 now appear over wires 26 of the second set. The weaving continues according to this new alternate relationship until a new pattern change is made.

It is evident of course that Figures 1 and 2 represent only two pattern areas, but in the preferred embodiment the fabric will consist of more than two such areas, varying in contour at different points weftwise. There may of course be any desired number of different pattern areas.

While in Figures 1 and 2 I employ two binder warps and the stufier warp, I may if desired use a binder warp 22 woven in opposition to a stuffer warp 23' which may be either the usual rather stiff stufler warp, or any compromise between the usual stufier warp and the normally more pliable binder warp.

In inserting the wires of the two sets as shown in Figure 3, it is preferable to use a double wire motion, inserting wires 25 from the left and wires 26 from the right for example. The heads of the respective wires are shown at 28.

It will thus be evident that a very rapid weave is provided, since it is possible to insert a wire with each weft, to eliminate back wefts, and to employ separate wire motions at the opposite sides.

Figures 5 and 6 are views of the faces of illustrative fabrics according to the invention.

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

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

ha in A A one-shot pile floor covering fabric comprising pile warp ends, binder warp ends and wefts interwoven together, the binder warp ends crossing between each weft, the fabric having first pile areas of one character in which a first group of pile warp ends is raised in pile of a first character over even numbered wefts and bound beneath odd numbered wefts and a second group of pile warp ends is raised in pile of a second character over odd numbered wefts and bound beneath even numbered wefts, the fabric having second pile areas of another character in which the first group of pile warp ends is raised in pile of the second character over odd numbered wefts and bound beneath even numbered wetts and the second group of pile warp ends is raised in pile of the first character over even numbered wefts and bound beneath odd numbered wefts, the pile warp ends floating clear at the back of the fabric behind two wefts at points of pattern change from a pile area of one character to a pile area of a difierent character.
