ADAM BOLLENTIN, OF NEIV YORK, N. Y.

TUFTED WOVEN FABRIC.

SPECIFICATION forming part of Letters Patent No. 468,051, dated February 2, 1892.

Application filed March 27, 1891- Serial No. 386,635. (No model.)

To all whom, it may concern.-

Be it known that I, ADAM BOLLENTIN, of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Tufted Woven Fabrics, of which the following is a specification.

This improvement relates to tufted woven fabrics especially suitable for rugs, but which may be made of various materials and weights to adapt them to various other uses.

A fabric embodying my invention consists of warp and weft and a series of tuft pieces, each of which is looped partly around one warp-thread on one side or face thereof and partly around an adjacent warp-thread on the opposite side or face thereof, and the tufted ends of which project from the web of the fabric, one end on one face and the other end on the other face thereof.

My invention is illustrated in the accompanying drawings.

Figure 1 represents a transverse section of two warp-threads and a tuft piece which is looped around the upper side of one and the under side of the other warp-thread, illustrating the way in which the tufts are combined with the warps in. my fabric. Fig. 2 represents asection of a piece of my improved fabric, taken parallel with the weft. Fig. 3 represents a section of the same, taken parallel with the warp. Figs. 4 to 10, inclusive, represent portions of a loom which may be employed for the manufacture of my fabric, showing those parts of the said loom which produce the looping of the tuft pieces around the warp-threads in different positions.

Similar letters of reference designate corresponding parts in all the figures.

a a are the warp-threads, and h b the weft.

The letters 0 c c c designate the tuft pieces, these four letters being employed to indicate the different parts of a tuft piece.

In Fig. 1 the portion 0' of the tuft piece is shown as looped partly around the warpthread a on the under side or face thereof and partly around the warp-thread ct on the upper side or face thereof, the end 0 projecting above the warp and the end 0 projecting below. Each tuft piece is thus looped around two warp-threads in opposite directions, and its tuft ends 0 and 0 project from opposite sides of the web of the fabric between the successive shots of weft, as may be understood by reference to Figs. 2 and 3.

.This fabric may be produced in various ways and may be woven in a loom of any suitable kind. I do not confine myself to any particular method of weaving or to any particular kind of loom or mechanism for the purpose. I will, however, describe, with reference to Figs. 4 to 10, certain parts of a loom and their operations by which the fabric may be produced. D d designate an ordinary loomreed. F. c E e designate two toothed racks arranged in front of said reed, the upper rack having its teeth 6 presented downward and the lower one having its teeth 6' presented upward. These racks are intended to have imparted to them at proper intervals, as will be presently explained, a longitudinal movement across the reed, the movements of the two being simultaneous, but always in opposite directions. Above the reed and at a suitable distance in front of it is a horizontal bar F, which carries a number of tubes f, here represented as equal to half the number of warp-threads in the fabric minus the selvage-threads. The yarn from which the tufts are made is supplied through these tubes from a series of beams or rollers, said rollers or beams and tubes and their appurtenances resembling substantially those employed in well-known looms for weaving tufted fabrics. Under the said bar F and tubes f is arranged a series of nippers g, one for each tube.

To explain the method of inserting and knotting the tufts by the means herein represented, I will first suppose the parts to be in the position indicated in Fig. 4, the rackbars E E having their teeth opposite the dents of the reeds and the nippers being depressed below the reeds. For the purpose of better illustrating the operation I have represented the warp-threads shaded alternately light and dark, the light threads being designated by a and the alternating dark ones by a. The necessary movements of the parts take place in the following order:

First. The shed is opened, as illustrated in Fig. 5, wherein the warp a is shown raised and the warp a depressed.

Second. The movements of the racks take IOO place, the upper one E moving to the left and the lower one E moving to the right, as shown in Fig. (5.

Third. The nippers 9 rise between the threads at a and seize the end of the tuftyarn 0*, which protrudes through the bottom of the tubef, as shown in Fig. 7.

Fourth. The nippers g descend a distance equal to the length of yarn required for a tuft piece-that is to say, sufficient to form the loops 0' 0 around two threads a a of warp and form two tufts c c projecting from opposite sides of the warp. In this descent the said nippers carry the tuft-yarn from the tube fdown between the warp-threads to a proper distance below the open shed, as shown in Fig. 8.

Fifth. The rack-bars E E are moved back to the position first mentioned, corresponding with Fig. 5, thus causing the tuft-yarn 0* between the' tubef and the nippers g to take a zigzag form, as shown in Fig. 9.

Sixth. The shed is closed and the yarn is then cut off near the bottom of the tube f. This closing of the shed causes the warpthreads to bend or loop the tuft piece over the top of warp a and under the bottom of warp a, as shown in Fig. 10. The looping of the tuft piece is thus completed, one end 0 being left projecting above and the other end 0 projecting below the warp. One or more shots of filling are now put in as in ordinary plain weaving.

The manufacture of the fabric is a repetition of the above-described operations.

The fabric thus produced has both sides alike, and the tufts are very securely held in place.

That I claim as my invention, and desire to secure by Letters Patent, is

The tufted fabric herein described, consisting of warp and weft and a series of tuft pieces, each of which is looped partly around one warp-thread on one side or face thereof and partly around an adjacent warp-thread on the opposite side or face thereof, and the tufted ends of which project from the web of the fabric, one on one face and the other on the other face thereof, substantially as herei n described.
