DOUBLE-PILE FABRIC.

Application filed December 5, 1923. Serial No, 678,778.

To all whom t may conce/m.'

Be it known that I, EDWARD J. DACEY, a citizen of the United States, residing at Worcester, in the county of lVorcester and State of Massachusetts, have invented a new and useful Double-Pile Fabric, of which the following is a specification.

This invention relates to a double pile fabric, particularly adapted for carpet manuacture.

It is the object of my invention to provide an improved double fabric in which both the upper and lower fabrics shall have substantially the structure of a vWilton carpet.

lVith this general object in view, my invention consists primarily in the provision of a double fabric in which two complete sets of pile warps are used, one set in each of the upper and lower fabrics respectively,

y invention further consists in the provision of a double fabric in which the pile tufts are more firmly secured in the fabrics than in fabrics heretofore made.

I also provide a fabric in which the weaving of solid colors may be more easily and satisfactorily accomplished.

My invention further consists in certain arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

Two forms of the invention are shown in the drawings, in which- Fig. 1 is a longitudinal sectional elevation of a three-shot weave embodying my improvements, and

Fig. 2 is a similar view of a two-shot weave.

Referring to Fig. 1, I have shown a double pile fabric comprising upper binder warp B and B', lower binder warp C and C, stuft'- er warps S which may be used or not as conditions indicate, upper pile warps 10, 11, 12, 13 and 14 and lower pile warps 20, 21, 22, 23, and 24. I have also shown filling shots 30, 31, and 32 in each crossing of the binder warps in the upper fabric and corresponding filling shots 40, 41 and 42 in the lower fabric.

Reading from left to right of the drawings, after each crossing of the binder warps B and B', and C and C', filling shots 30 and 40 are inserted on the inner or pile faces of the fabric. One of the pile warps, in this case the warp 20 in the lower fabric, is then raised and passed entirely through the upper fabric` and around a iilling shot 31 at the outer or back face of the fabric. A corresponding filling shot 41 is inserted at the back of the lower fabric. The pile warp 20 is then brought back to the lower fabric and filling shots 32 and 42 are inserted before the binder warps are again crossed.

As shown in the drawing, the lower warp 21 is next called, followed by the upper warp 12, the upper warp 10, the corresponding lower warp 20 and the Lipper warp 10. Particular attention is called to the alternation of the warps 10 and 2O when two or more successive picks of the same kind or color of pile warp are required.

When the fabric is cut, the tufts formed by the ends of the loops of pile warp are found to be secured in the fabric by passin twice through the entire fabric and aroun the back filling shot 31, thus forming a secure and satisfactory tuft. For the other part of the tuft in the opposite fabric, the pile ends are attached to the pile warps einbedded in the fabric. By calling the same kind or color of warp alternately from the upper and lower fabric, I avoid placing successive loop tufts in the saine fabric, as each alternate tuft is connected to a pile warp embedded in the fabric. In this way a firm and durable weave is secured and both the upper and lower fabrics each contains a full body of pile warps.

In Fig. 2 I have shown a substantially similar construction in which two shots only of filling F are inserted after each crossing of the binder warps W. Two full sets of pile warps are provided, one in each layer of fabric, and warps of the same kind or color are called alternately from the upper and lower fabrics as previously described.

It is desirable in both the two-shot and the three-shot weaves that the same kind or color of pile warp be called alternately from the upper and lower fabrics, even when not used on successive picks, as this causes a similar amount of warp of a certain color to be used from the creels or spools supplying the two fabrics. It will be noted that each pile warp after being called invariably returns to the fabric from which it was taken.

Having thus described my invention and the advantages thereof I do not wish to be limited to the details herein disclosed othern wise than as set forth in the claims, but What claim iszl. A double pile fabric comprising binder Warps, a complete set of pile Warps in a single reed space for the upper` fabric, a second complete setof pile Warps in the same reed space for the lower fabrics, and a plurality of filling shots inserted after each crossing of the binder Warps and securing the pile tufts in each fabric.

2. A double pile fabric comprising binder warps, a complete set of pile Warps in a single reed space for the upper fabric, a second complete set of pile Warps in the saine reed space for the lower fabrics, and a plurality of lling shots inserted after each crossing of the binder Warps and securing the' pile tufts in each fabric, the pile war-ps of corresponding kinds or colors being called alternately7 from the upper and lower fabrics.

3. A double pile fabric comprising binder Warps, a complete set of pile Warps in a single reed space for the upper fabric, a second complete set of pile Warps in the same reed space for the lower fabrics, a pair of filling shots inserted after each crossing of the binder Warps on the pile face lof each fabric, and a single filling shot inserted after each crossing` of the binder Warps on the back side of each fabric.

4. A double pile fabric comprising binder Warps, a complete set of pile Warps in a single reed space for the upper fabric, a second complete set of pile Warps in the same reed space for the lower fabrics, and a plurality of filling shots inserted zafter each crossing of the binder Warps, each raised pile Warp passing entirely through the opposite fabric', around a. filling shot at the back thereof, and again through the fabric and back to the fabric from which it was taken.

In testimony whereof I have hereunto affixed my signature.

EDWARD J. DACEY.
