LOOM FOR WEAVING TUFTED FABRICS,

SPECIFICATION forming part of Letters Patent No. 270,346, dated January 9, 1883."

Application filed November 4, 1881. (No model.)

To all whom it may concern:

13c it known that I, CHARLES EDWARD SKINNER, of Yonkers. in the county of Westchester and State of New York,have made an invention of certain new and useful Improvements in Looms for \Veaving Tufted Fabrics; and I do hereby declare that the following, taken in connection with the accompanying drawings, is a full, clear, and exact description and specification of the same.

Theinvention relates to looms for weaving tufted fa brics-such, for example, as Moquette carpets; and the imprhvements have reference to the means for placing the tufting material in the body of the fabric, composed of warpthreads and filling, the mode of operation of such means being that the tufting material is inserted between the warp-threads by inserting devices operating at one side of the warp, and has its ends pulled back to the side of the warp from which it was inserted by hooks introduced between the warp-threads for that purpose.

The manner in which the operation is effected in the loom in which I have embodied my invention is as follows: The tufting material is carried on spools, the same as are used No.186,374, and each of said spools is connected with a spool frame, which is fitted either with a row of needles or with a row of tubes, one for each tuft, to be inserted in a line crosswise of the fabric. Each needle or tube is extended beyond the eye or place at which the tinting-yarn protrudes, and the extension has the form of a book. The spool-frames are brought in succession to the place where the tnlts are inserted by mechanism such as is described for the. purpose in said Patent No. 186,374, or by some substitute therefor, and each spool-frame is so operated as to first insert the trifling-material yarns between the warp-threads and then to hook up the ends of the said material, so as to leave loops thereof in the fabric.

In order that my invention may be fully understood, I have represented in the accompanying drawings, and will proceed to describe, portions of a loom embodying the invention.

sented or described may be constructed as the corresponding parts are in the loom described in the said Patent'No. 186,374, or in any other satisfactory manner.

Figure 1 represents a cross-section of the loom, showing certain parts thereof. Figs. 2 to 11, inclusive, represent detached parts of the loom.

The loom embodying the invention is of course provided with the customary means for holding and moving the warp-threads and for introducing the weft or filling, the latter beinginserted through the shed ofwarp-threads,

preferably, by a weft carrier or needle. The loom is also provided with chains or other the tufting materiahand for presenting them to and taking them from the devices which move the spool-frames for the insertion of the tufting material into the warp of the fabric being woven. Cutting mechanism also must material remaining on the spool.

The devices which I prefer to use to move the spool-frames for the insertion of the tufting material are a pair of transferring-arms, K, (one at each side of the loom,) which are connected with a rock-shaft, K and are controlled by a cam, K (shown separately in Fig. 9,) springs, if necessary, being provided to facilitate the movement. The cam K is secured to the ordinary cam-shaft, G, of the loom, and this cam operates upon the transferringarms K through the intervention of the truck or friction wheel K the cam-lever K the rod K the rock-shaft arm K, and the rock-shaft K Each transferring-arm K is provided atits end with a clutch to grasp the end of the oted to a rock-shaft arm, K, so that the transferring-arms may be moved laterally to enable their clutches to grasp and to release the spoolframe. All the parts thus far described may be constructed and operated substantially as described in said Patent No. 186,374, the cams, however, having their grades of the forms required to impart the movements hereinafter described.

The sp0ol-frames H may be ofthe same gen- The portions of the loom 'which are not repreeral construction as those described in said spool-frame, and each transferring-arm is piv means for carrying the spool-frames holding he provided to cut the tufts from themass of IOO Patent No. 186,374feac'h being fitted with a I spool, H, for the tufting material, with aspringbrake, (to hold the spool from turning, except when the material is pulled otf,) and with a row of tubes, H to hold the ends of the tufting material. In case tubes be used for this purpose, each, (see Fig. 8,) in order to embody my invention, should be extended beyond the orifice at, at which the tul'ting material protrndes, and the extension must have the form of a hook, to. If needles be used to hold the tufting material, they should be extended beyond their eyes, and the extensions should be formed into hooks similar to those above described, the characteristic feature of this part of the invention being that the tubes or other tut't material inserting devices, which are moved by mechanism at one side of the warp for the purpose of insertingthetufting between the warp-threads, are combined with hooks that are moved forward from the same side of the warp as the tubes are, tor the purpose of pulling the ends of the tufting material back to the side of the warp from which they are inserted by the tubes.

A needle constructed in one piece with its corresponding hook is represented at Figs. 10 and 11, such needle in this instance being at tached to the rear side ofthe bar H (by which it is moved).instead of to the front side thereof, (as the tube previously described is represented to be,) and the tutting material being wound in the reverse direction upon the spool. Such hook-needles are the equivalents of the hook-tubes above described. The tulting material, when inserted between the warp-threads, is secured by a shoot of filling, which is illserted by the weft-carrier and is beaten up by the lay of" the loom. In practice three shoots of coarse filling and one of finer quality may be inserted and woven into the fabric for each row of tufts introduced. In such case the laycam F should be fitted with three projections, ff f, for beating up the coarse filling, and with one,f for beating up the fine filling, and the projections for beating up the coarse filling may be double, so as to give a double beat of the lay for each shoot of such filling.

I prefer to operate the above-described mechanism as follows: When the transferring-arms K have seized a spool-frame, H, and

' brought it, by the action of the grade 1 of the cam K to the vicinity of the tell of the fabric being woven, as represented at Figs. 1 and 3, the following movements of the parts of the loom are effected-via, first, the spool-frame is lowered or depressed, as at Fig. 4, by the continued action of the grade l of the cam, to introduce the ends of the tufting material between the warp-threads; second, the spoolframe is raised sufliciently (by the grade 2 of the cam K to raise the tubes out of the fabric, as shown at Fig. 5, leaving the ends of the tutting material between the warp-threads and protruding beneath the warp; third, a shoot of line filling is then introduced behind the tufting material and is beaten up by the lay, and

the praoticalefi'eot of this beating up is to cause the ends of the tufting material beneath the cloth to bend backward in the loom, as represented at b, Fig. 6; fourth, the spool-frame is lowered a second time, (by the grade 40f the cam K so as to introduce the hooks a between the warp-threads and depress the hooks beneath the warp, where the hooks engage with the ends I) of the tufting material, as represented at Fig. 6; fifth, the spool-frames are raised, (by the grade 5 of the cam K and this movement causes the hooks to pull the ends of the tufting material upward between the warpthreads, as represented at Fig. 7; sixth, the spool-frame is held at rest while a shoot of coarse filling is introduced and is beaten up by the lay F, such holding at rest being effected by the action of a concentric grade, 6, of the can] K seventh, the spool-frame is raised slightlv, (by the action of the grade 7 of the cam K so as to pull off of the spool a sufiicient length of tut'ting material for forming the next row of tufts from the satne spool; eighth, the spool-frame is held at rest by the action of a concentric grade, 8, of the cam K, while the cutting mechanism operates to cut loose the tufting material held in the fabric from the residue on the spool; ninth, the spool-frame is raised by the action of the grade 9 of the cam K, to be restored to the carrying-chains.

The above movementsinay be varied, as found expedient, to suit the peculiar construction and operation ot the loom to which the invention is applied, provided the tubes or other tultinginserting devices be so operated at one side of the warp as to insert the tut'ting material between the warp-threads, and the books he so operated as to draw back the ends of the tuftingmaterial to the side ofthe warp from which they are inserted.

In order to insure the seizing of the ends of the tul'ting material bem-ath tne fabric by the hooks. they may be lowered and raised additionally between operations 5 and 6 above mentioned.

I claim as my invention- 1. The spool-frame fitted, substantially as above described, with a row of hooks to pull the ends of the tutting material through the warp.

2. The combination, substantially as before set forth, of the transt'erring-arms of the lootn and the spool-frame fitted with a row'of hooks.

3. The combination, substantially as before set forth, of the tuft-inserting de ices with mechanism which causes them to insert the tut'ting between the warp threads from one side of the warp, and with hooks which are operated to draw back the ends of the tufting material to the side of the warp from which it is inserted by said tuft-inserting devices.

In witness whereof I have hereunto set my hand this 27th day of October, A. D. 1881.

CHARLES EDWARD SKINNER.
