IMPROVEMENT IN CARPET-FABRICS.

Specification forming part of Letters Patent No. 162,385, dated April 20, 1875; application filed March 13, 1875.

To all whom it may concer-n Be it known that I, SAMUEL HORNEE, Jr., of

Philadelphia, Pennsylvania, have invented an Improved Carpet-Fabric, of which the following is a specification:

The object of rny invention is to manufacture a dainask carpet-faln-ic, in which the etfect of an additional ply is produced without the employment of an additional set of figuring warp-threads, and this object I attain in the manner in which I will now proceed to describe, reference being had to the accompanying drawing, in which- Figure l is a face view of a strip of my im proved carpetfabric; and Figs. 2, 3, and 4, diagrams, illustrating the construction of the saule.

The drawing illustrates my invention as applied to a two-ply fabric, A and B representing the two sets of warp-threads, D the thick weft or lilling threads, a the fine wefts, and b fine warp-threads introduced for a purpose explained hereafter.

In ordinary damask carpet-fabrics, the thick weft or filling threads are entirely concealed from sight, being embedded between the warpthreads which form the front and back of the fabric, so that the production of a two, three, or four ply pattern requires the employment of a like number of sets of warp-threads. I attain the e'ect of an additional ply without the use of an extra set ofgurin g warp-threads by sinking all the said warps to the back of the fabric, at the proper points, by means of the jacquard, thus bringing the thick weftthreads to the face to aid in forming the pattern.

The warp-threads A and B are controlled both by a jacquard apparatus for lifting the proper threads to form the pattern, prior to the introduction of the thick weft-thread D,

and by a set of ordinary harness by which the threads are lifted in alternate sets, after each insertion ot' the thick wefts, for the in- Sert-ion ofthe fine weft-threads u..

To prevent the iioating of the thick weftthreads D, where they are brought to the su rface, and to bind the whole fabric firmly together, I employ in the present inst-ance two sets of line warp-threads, b, which are lifted' alternately prior to the insertion of the said weft-threads D.

The fine warps b are not lifted with the warps A and B, prior to lthe introduction of the line wefts; hence each thread I), afl er passing over one of the thick wel'ts D, passes under two tine wefts and a thick weft before again passing over a thick weft, as shown in Fig. 2, the effect of this operation being to firmly bind the said threads D to the backingthreads, and to form a compact fabric.

It will be evident that, although I have illustrated and described my invention as applied to a two ply fabric, it may be applied with good results to fabrics having three or more sets of warp-threads, and that it may also be applied to shawls or other fabrics.

I claim as my invention- A damask carpet-fabric in which the entire number ot' figuring warp-threads are carried to the back of the fabric, at intervals in order to allow the thick weft or lling threads to be brought to the surface, all substantially as and for the purpose set forth. n

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
