To all whom it may concern:

Be it known that we, WILLIAM H. Coornn and CHARLES H. COLLINS, each a citizen of the United States of America, the said nL- LIAM H. COOPER residing at Amsterdam, in the county of Montgomery and State of New York, and the said CHARLES H. COLLINS residin at Albany, in the county of Albany and tate of New York, have invented certain new and useful Improvements in Tapestry-Looms, of which the following is a specification.

Our invention relates to tapestry looms, and the object of our invention is to provide an improvement in tapestry weaving looms, whereby the border yarn and body yarn may be woven into the tapestry together with the jute and pile threads, and means for causing either the border yarn or the body yarn to be exposed or buried as desired in order to form the proper pattern or design of the woven tapestry; together with such other elements and combinations as are hereinafter more particularly set forth and claimed.

We accomplish these objects by means of the mechanism illustrated in the accompanyin? drawings, in which:

igure 1 is a side elevation of a tapestry loom, partly in section, provided with our invention.

Fig. 2 is a perspective view, partly in elevation, showing the means for operating the heddle frames.

Fig. 3 is a side elevation showing the position of the yarns and heddle frames during the first cycle when the border yarn is brought to the surface.

Fig. 4 is a side elevation of the heddle frames, showing the position of the yarns during the second cycle, when the body yarn is brought to the surface.

Fig. 5 is a side elevation of the heddle frames, showing the arn-When a difierent tapestry is being ma e from that shown in Figs. 3 and 4.

Fig. 6 is a perspective view, with parts broken away, of the tapestry in course of manufacture, showing the first and second cycles.

Fi 7 is a perspective view of a rug, showing t e outline thereof.

Similar letters refer to similar parts throughout the several views.

In the manufacture of tapestry Brussels carpets and rugs, the present process is .to wind the plain worsted yarn onto large drums varying from five to eighteen feet in diameter. Each drum when filled with the plain or worsted yarn represents one thread in the pattern or design running lengthwise of the rug. A. great number of drums, by this process, have to be printed and every one difi'erently to complete the design. The printing of these yarns or threads is a long, tedious and expensive operation. After the yarn is printed it is taken off the drum, steamed, washed and dried, all requiring separate operations. The long printed skeins of yarns are then wound on small spools and taken to a machine called a setting frame. Each individual spool placed on said setting frame represents one thread of the design, and the 'difi'erent processes through which the yarn is to go after being printed causes the difierent threads to come at difierent lengths. This difi'erence in length is caused by their not drying alike, or the drums are not exactly of the same size, or the yarn may be stretched by being spooled before being printed; and sometimes the chemicals affect the length of the yarn. In the practice at this well-knownprocess in order to get the design properly, it is set on a machine called a setting frame. Each thread is brought to its proper position and clamped, all of which requires time and attention and adds to the cost of the fabric.

One very popular rug is that which is shown in outline in Fig. 7, which is'usually 9X12 feet and has for its center, M, some solid color, with the border, L, of a darker shade running all around it.

It is a very simple matter to get the desired efiect with dyed yarn so far as the design is concerned, running lengthwise of the portion, L, L, as all it would be necessary to do would be to wind the plain colors onto the large beam with the threads placed in their proper order. The beam will then be filled without any more labor. But on account of the dark border or band, L, running crosswise of the design, it is necessary to put the dyed yarn through the exact operation it would require if the yarn were of white or plain threads. This would mean the drum printing and pattern setting operations.

By our invention applied to a tapestry Brussels loom, we are able to make a perfectly demgl ed fabric which has the appearance of ill) ' no part of which is liable to be'afiected by body Brussels or Axminster goods in which we use all dyed yarn instead of surface and bury' the body yarn and at the same time weave into the carpet or rug the bod yarns, brin ing them, the body yarns, to e surface an burying the border yarns, when that part of the rug, which will be the central portion, is being woven.

This makes a very strong, serviceable rug,

shrmking or otherwise from causes growing out of the old method'of procedure as hereinbefore set forth.

. We will now proceed to describe our infvention, referring to the several figures.

In-F1g. 1 we show the frame, A, of the machine provided with the beam B, carrying theborder yarn; the beam, carrying the body yarn; the beam, D, carrjimg the jute, and the double beam, E,'whic carries a double chain of cotton yarn. F, is a spike roller and G, the take-up roll. We rovide five heddle frames. heddle; 11, is the border yarn heddle; 12, is the jute heddle; 13, is one of the cotton yarn heddles, and 14, is the other cotton yarn heddle. H, is the pile wire, and J, is a shuttle. K is a reed.

In order to roduce a, rug such as that shown in Fig. 2, we must have the border yarn brought to the surface along the border, L, L, of the rug, and the body yarn brought to the surface along the portion, M, 0 may wish to weave into the rug the body yarn, jute and cotton chain as well as the border yarn. 3

We will now proceed to describe the man ner of weaving the rug shown in Figs. 6 and 7.

'In the first pick, the, position of the heddles, pile wire, shuttle and yarns is shown at the left of Fig. 3 and also at the left of Fig. 6. The border yarn, N, from the beam, B, passes through the aperture in the border yarn heddle frame, 11, and over the pile wire,-H. The body yarn, O, is buried beside the jute, P, and while the shuttle, J, is beneath both the jute and body yarn, one of the cotton arns, a, is beneath the filling thread, I), an the other cotton yarn, 0, is above the filling thread, 6. This makes up the first pick.

The second pick isshown next to the right of the firstin Fig. 3. When the border yarn, N, and the body yarn, O, are buried, one of the cotton arns, a, is below the filling thread and the ot er yarn, 0, is above. Between the second and third picks the yarns, a and a,

printed yarn, which makes a better fabric at a much 7 10, is the b0 yyarn the rug, and at the same time we The fourth pick, at" the extreme right of Fig. 3, is just the same as the first ick. Now again the border yarn is looped a ove the surface. This completes the first or border yarn cycle, and is 're eated as many times as is necessary in or er to form, the border according to the plan or design.

In Fig. 4, we show the body yarn cycle. In the first pick, in which the body yarn heddle, 10, is raised so as to form a loop, 0, the pile wire, H, passes under the ody yarn, 0, making the loop. The border yarn, N, slde by side with the jute, P, and the cotton yarns are woven into the filling as in the case first above described. 7

The second pick and third pick are just I the same as the second and third picks .of the border ,yarn,cycle. In the fourth pick the body yarn is looped again so that the heddle,-10, is raised the same as in the first pick of the second or body yarn cycle.

-' It will be noted that there is a difference in the height to which the heddles are raised in makin our rug. When it is necessa to make t e loop, as in the first and fourth picks, of each of the border and body yarn cycles, we raise the heddle carrying the yarn which it is desired to'loop to the highest point; then, at the same time, we weave in the jute one of the cotton yarns together with either the body or border yarn,-the one which we wish buried,--at a medium height of their heddles, respectively, while the other cotton yarn heddle is down at the lowest position.

In Fig. 2, we show the device which is-an important part of our invention for thus providing for the proper position of the eddles. To the heddle, 10, is attached the rod, 7 connected with the lever, g, fulcrume at h. The lever, g, is attached to the rod, 7'. The end of this rod is adapted to reciprocate in a slot, is, and housing, R, attached to the cam lever, S. The opposite end of the heddle, 10, is connected with the rod, f, which is connected to the lever, g, fulcrunied at h, which-"is connected with the'rod, 7", which is ada ted to reciprocate in the opening, is, in sai housing, R.

The border yarn heddle, 11, has connected with it a rod, 20, which is connected with a lever, 21', fulcrumed at k, which lever is connected with a rod, 22, adapted to reciprocate in an opening, 23, in the housing, 24, on the cam lever, T; while the other end of the heddle, 11, is connected with the rod, 25, which is connected} to the lever, 26, which is fulcrumed at 7b, to the end of which is connected the rod, 27, which reciprocates in the opening, 28, in the housing, 24. The cam levers, S and T, engage the cam wheels, Yand Z, mounted on the cam shaft, X. Oneach of the cam levers, we provide a hand-operated locking hook, V, adapted to engage with a locking lug, p, one of which is on the rod, 22, and the other on the rod, j. When we wish to raise the heddle, 11, to its highest position, we lock the hook, V, over the lug, p, on the rod, 22, and when the cam wheel, Z, is

-in the position shown in Fig. 2, the lever,

T, being depressed, the lug holding the end of the rod 22, to its extreme inserted position in the housing, 24:, will rock the lever, 21, on its fulcrum, h, and draw the heddle, 11, to its highest position. The heddle, 10, is not raised to its highest position since the hook,- V, thereon is out of engagement with the lug, p, and the housing will move on the rod, j, causing the rod to operate the lever, 9, only far enough to raise heddle, 10, to its intermediate position. There may be placed a pin, 90, against which the hook, V, will engage when in the locked position, holding the hook in place, and a pin, 95, to keep the hook from falling when out of engagement with the locking lug, p. The tendency of the heddles, 10 and 11, to fall to the lowest point in the shed when the hooks, V, are unlocked is overcome by the threads passing through the heddles which tend to support them; but to form a more substantial prevention we may place a bolt or pin, 98, projecting from the frame a sufiicient distance to enter the path of movement of the levers, 21, and g, and thus act as a stop limiting the downward movement of the heddles.

The heddles, 12, 13 and 1a, are operated in the usual. manner in carpet weaving machines.

\Vhen a rug similar to that shown in Fig. 7 is woven, beginning, for instance, at the left of the figure, by weaving the border, L, straight across requiring a border yarn to be brought to the surface, the. weave will be that shown at the left of Fig. 6 and marked Border yarn cycle. During this weaving the position of the several heddles in the several picks is indicated in Fig. 3.

" After the border, L, has been woven and we are to weave the border, L, body M, and border, L, the yarn from a beam containing the colors required to thus produce the border and body is woven as shown in Fig. 4, entitled Body yarn cycle, and which is illustrated also at the right of Fig. 6. Thus,-

if the body. M, of the rug is to be green and the borders black, the yarn on the beam for use during the body yarn cycle willbe placed in the order of black, green, black.

We have shown in Fig. 5 the position of the heddles and yarns for making a twoshot fabric in which in the first pick, at the left of the figure, the border yarn, N, is looped the same as in the first pick in Fig. 3.

In the second pick both the border and body yarns are buried and the cotton yarn is on the surface; while in the third pick, when the border yarn is looped and the jute and body yarn are on the surface, the cotton yarn, a, is depressed and the cotton yarn, c, is at the surface.

It is apparent that we can arrange these yarns in any desired order; but What we especially desire to accomplish is that of constructing figured rugs out of dyed yarn, making the lines of demarcation straight, without drum printing or setting the border ends.

What we claim as our invention and desire to secure by Letters Patent is:

1. In a tapestry weaving loom, a series of heddles, one through which the border yarn passes and the other through which the body yarn passes; lever and rod connections with each of said border and body yarn heddles; cam operated levers; a housing carried by each of said levers; rods connected with each of said heddles, respectively, adapted to reciprocate in said housing; and means for locking each of said cam levers in connection with the rod connected with its housing, substantially as described.

2. In a tapestry loom provided with one or more border yarn beams, one or more body yarn beams, jute and cotton beams mounted in the usual manner; a series of heddle frames; heddles in said frames carrying the body yarn, border yarn, jute and cotton yarns; a cam shaft; cam Wheels on said shaft; cam levers engaging said cam wheels; means for connecting the border yarn heddle frame with the cam levers; means for connecting the body yarn heddle frame to the cam levers; said connecting means being adapted to permit of the motion of the cam levers without moving the heddle frames; said connecting means provided with a lock which, when closed, causes the movement of the heddle frames under the direction of the cam levers, substantially as described.

In testimony whereof we have afixed our signatures in presence of two witnesses.
