SPECIFICATION forming part of Letters Patent No. 397,156, dated February 5, 1889.

Application filed September 9, 1887. Serial No. 249,205. (No model.)

To all whom, it may concern.-

Be it known that I, ALWILL URBAHN, at present residing in Nagelsbaum, near Burschcid, Germany, have invented an Improvement in Looms, of which the following is a tion, the weftcarrier being moved to nearly the middle of the loom. Fig. 2 is a front elevation, partly in section, of said loom. Fig. 3 is a front view, on an enlarged scale, of part of the reed and upper .needle-heddlc, showing also the adjoining parts of the loom. Figs. 4-, 5, and

6 are detail sectional views showing the different positions of the warp and inlay thread during the operation of the loom.

Fig. 1 is a j perspective view of the guide for putting the inlay into place.

This invention relates to a loom of the general class described in my patent, No. 289,731, of December 4, 1883, and has for its object so to arrange the mechanism of the loom that an inlay thread or cord may be placed crosswise in the warp by a traversing guide with out the aid of a shuttle.

I find that when it is desired to weave into a fabric an ornamental cord of loose texture such as chenille or the likeit is not practicable to first wind such a cord on a spool or set of spools, because by so doing the looseness of the cord is lost. It would therefore be impracticable to weave such a cord into a fabric by carrying it in a shuttle in the usual manner. By my invent-ion these difficulties are overcome, and I am enabled to weave such an ornamental cord into a fabric with facility.

My invention consists in the details of improvement that I hereinafter more clearly point out.

In the accompanying drawings, the letterA represents the frame of the loomv B is the beam from which the grouml-warp or main warp is taken. The main warpthreads a Z) pass through heddles (J C in the usual manner to form a shed, d, of the ordinary kind. by cords a a from weighted levers b b that are pivoted at the upper part of the loom.

The heddles C C are suspended a The lower part of the heddles C O are connected by cords (Z d with treadles 6 6 that are pivoted at the lowerpart of the loom. By depressing the treadles the heddles will be lowered, the weights on the levers b 11 acting to raise said heddles; but said heddles may be operated by other suitable means, if desired. These main warp-threads a I) also pass through the reed D, which is attached to the batten E. The batten E is pivoted in the frame an d may be provided with a handle and operated by hand, or may be operated as shown in United States Patent No. 121,161, dated November 2], 187.1, or otherwise, as desired. The reed I) is composed of upright loops e c, as is more clearly shown in Fig. 3 of the drawings. Through these loops the warp-threads a b are passed. After passing through the reed, the warp-threads pass around a beam, F, and finally the finished fabric is received on a beam, G, to which ii'itormittent rotary motion is imparted by su itahle meehan ism. Part of the warp of the fabric to be produced is taken from the beam B, or any other suitable beam, through a needle-heddle, H. In the d rawin gs, the letter frepresen ts this additional or auxiliary warp.

The needle-heddle 11 consists of a heddleframe having downwardly-projecting pins g, which are perforated at or near their points, and through these perforations the threads of the auxiliary warp f are passed.

The n eedle-heddle H is suspended by a cord or strap, f from a suitable weighted beam, L, or otherwise, and connected by a cord, with a suitable treadle, 7: or other contrivance, so that up-and-down motion may be imparted to it. The auxiliary warp-threads f, after having passed through the needles 9 of the heddle II, are passed around the beam F, without, however, passing through the reed D. This, as appears more clearly from Fig. 4 of the drawings, leaves a shed, 72 above the shed (l, which shed h is open at the back. Into this shed h thus open at the back enters the cord or inlay-thread guide I, which is attached to a reciprocating traversing carriage, J, that travels on fixed rails i i. The ornamental or other cord j, which is to form theinlay of the fabric, is taken from a suitable boX'or receiver, M, in which it was deposited when manufactured, passed over guide-rollers m,

and through suitable guide-loops, a n, to the final inlay-guide l, which has loops 0 o and for finallyguidingthe inlay-cord to its place in the Shed 1i.

It will be pereeivml from Fig. 13 that the needles g of the heddle] l are above the spaces between the loops e o! the reed l). The ear riage J has reeiproeating traversing motion imparted to it by suitable means. drawings it is shown connected with the ends of a cord, g, which is attached to an oscillating lever, N, and passed over guide-roller; Cord Z is passed around a wheel or drum, m-, that; is suitably hung on the framing ol the loom.

at the side of the wheel m as shown in Fig.

2. By alternately depressing the treadles o i o the wheel m and thereby the lever N, will be oscillated, the lever N being secured to a shaft, L hung in suitable hearings in the loom, and the said shalt i carrying pulleyj around which passes the cord 7 \Vhen the lever N is moved from the position shown by :t'ull lines in Fig. 2 to the dotted position shown in the same figure, the

carriage J will benloved from the left to the right side of the loom, so as to deposit one la ver of th read or eord in the open shed 71. The loom is also provided wit h an ordinary shuttle, which isadaptmll to place a shuttle-thrcml, s, in the shed (I. This shuttle is indicated at P in Fig. 1, the letters R R in Fig. 2 indicating the picker-sticks, by which the shuttle is i or may be moved. These picker-sticks R R may be operated in any well-known manner, or as shown in United States Patent. No. 70,186, dated October 29, 1867, and need not here be further described.

The loom, being thus described with sullieient exactness, operates as follows: Ordinary fabric is woven in it from the warp-threads a l) with the z 'sistance of the shnttle-thread s, and into this ordinary fabric also enters the auxiliary warp j, which is raised or low ered to form part of the shed (Z when required. Thus in Fig. ti the auxiliary warp fis repreln the To the wheel m are also secured cords 1 u n 11 that are secured to treadles 0 carried 1 i sented as carried down to the lower part of the shed (I, the threads f passing between the loops 8 containing the warps a I), while in Fig. 5 it is represented as in the upper part of said shed. The shuttle is thrown from time to time to properly interlock with the threads of the warp a of; but when an inlay thread or eord j is to be placed into the fabric the heddle ll is raised, as in Fig. -:l-, to form the open shed l1, and the carriage J is then traversed or moved across the face of the loom from end to end, so as to lay one length of cord j into the shed h, whereupon the heddle II is lowered to carry its warp-threads f over this length of cord so deposited, and then the shuttle is thrown, as in Fig. 6. Thus l by means of this loom I may from time to i time, as occasion requires, lay into the fabric a length of cord j without being required to wind this fabric upon spools or reels, and without using a shuttle for depositing it in the fabric. The looped reed D, co-operating with the needle-hec'ldle H, prevents the auxiliary warp-threads J" from interfering during the up-and-down motion of the heddle H with the main warp-threads a 1).

l elaim- 1. In a loom, the cord-guide l, havingloops o and p, and its carriage J, combined with the lever N, cord q, connecting-carriage J, and lever N, shaft F, wheel J on said shaft, wheel m connected with. the wheel and. the treadles 0 connected with the wheel we, all arranged and o )erating substantially as herein shown and described.

2. The combination of the eord-guide 1, its carriage J, cord q, lever N on shaft 1' shaft i pulley 7' treadles 0 straps Z 12?, and wheel m all arranged for operation substantially as described.

In testimony whereof I have hereunto set my hand this 26th day of August, 1887.
