n 1 claim.

This invention relates to pile fabrics and more particularly to an improved weave for carpets and rugs having the pattern visible at the back.

There is a demand for Axminster rugs and carpets which resemble Oriental rugs by having the pattern reproduced on the back, and the binding structure of the ground fabric well concealed by therpile forming yarn.

The present invention relates to a pile fabric constructed to meet these requirements and which presents a good pile area with the tufts firmly held in place and which may be readily woven on an Axminster or nipper type of loom.

In accordance with the weave of the present invention the pile forming tufts extend downwardly between the stuffer warps and are looped about a lower weft shot and lie between upper shots of weft disposed at the opposite sides of l the transverse row of tufts. As a result of this Aconstruction the pattern is well defined on the back of the fabric and the tufts are firmly supported in an upright position by the upper shots secured at their opposite sides.

n The fabric may be woven by inserting three Ashots of weft and a row of tufts to the cycle, one shot being inserted below the vplane of the stuffer warps and two shots above this plane. The

pair of upper rshots are preferably bound one against the other to form a firm support between the rows of tufts and serve to hold the tufts looped about the lower shot and to maintain themv in an upright position.

The novel weave of the present invention will Abe further understood from the following description when read in connection with the accompanying drawing showing one good practical embodiment of the invention.

In the drawing:-

Fig. 1 is a plan view of the upper face of a.

piece of rug or carpet constructed in accordance with the present invention;

Fig. 2 is a view of the back of the fabric of Fig. 1 showing the pattern on the back;

Fig. 3 on an enlarged scale is a longitudinal sectional view of the fabric; and

Fig. 4 is a transverse sectional View of the fabric of Fig. 3. f

The embodiment of the invention illustrated in the drawing is a two plane fabric having the approximately straight stuifer warps 10 all laid in a single plane, and the fabric is woven with three shots of weft and a row of tufts to the cycle,A one shot 11 of the cycle being placed be low the stuffer warps and the two remaining shots 12 and 13 are laid above the stuffer warps. Each of the shots is shown asformed of two strands of kweft laid by the in-and-out travel of the weft inserting needle. Y 1 The tufts 14 forming the cut pile surface are carried down throughthe ground structure and 6.0'-

looped about the lower weft shot 11, as Shown. This reproduces the pattern at theV back and forms a Vsoft wool back at the lower face ofthe fabric, and it also helps to conceal the ground structure. I

The upper'shots 12and` 13 of a cycle' are preferably placed in,v close relation with each other, as shown, so that they form a firm rib or support extending transversely of the fabric between the rows of tufts and engage the Yopposite sides of the transverse rowoff tufts to support the tufts in an upright position.

Each lower weft shot 11 preferably lies centrallyA 5 between the adjacent pairs of Yuppershot's 12 and 13, as shown, and the upperpair of shots are placed sufliciently closetogether to snugly embrace the row of tuftstherebetween sonas, to

firmly secure the tufts about the lower holding' shot 11V and support the tufts 'uprightf This l v crowding of the upper weft `shots togetherserves also to decrease the space between the rows` of tufts, which improves the appearance of the pile area and'helps to conceal the ground fabric. i

' The upper'and lower weft shots are firmly secured in place in the construction shown by a set of binder warps 15 that are looped around the lower shot 11 and extend-upwardly over the pair of upper shots 12 and 13 of a cycle. This serves to firmly bind the two upper shots 12 and 13 together and tohold the wefts, firmly'in` are provided between each pair of tufts, the chain being providedbetween the'two stuffer warps,v

The present fabric is well Vadapted to be wovenv on a two beam loom since the chain warps may be supplied from one beam 'and the pairs of stuffer warps may be supplied from a second but double'beam. The pile forming tufts may be inserted either by tube frames or nippers.

What is claimed is:-

As an article of manufacture, a carpet or rugy having a tuft` pile surface andcomprising a y, backing having a single series of stuffer warps i arranged in pairs, onevat each side of the pile forming tufts and extending longitudinally of the carpet or-rug in a'single stulfer plane, a shotv over the four contacting weft strands above the Y l stuer warps to bind the four strands closely together inv contacting relation, then .downwardly between the same pair of stuifer Warpsso that the loops of the tufts shall not be distorted laterally andthereby form'aeomplete coverage oi the backing with the reproduction of the pile surface pattern on rthe back. l l Y JAMES F. SHAW. JAMES M. DONNELLY. I JOHN SMART. JOSEPH J OHNSTON.'
