Abstract: 14,514. Naylor, T. F., and Hall, O. S. June 28. Looms, pile forming and cutting in; reeds; shedding-motions; picking-motions; weft carriers; weft, supplying; healds.-Relates to looms for weaving chenille or fur-pite fabrics, to produce carpets resembling hand tied or knotted Turkey and Oriental carpets and also for setting ordinary or fan-shaped chenille in chenille fabrics. Ordinary or plain fabric is woven at the end or commencement of a carpet by connecting the coupling-rods 28, Fig. 3, to two extra tappets, a fine weft being used. When weaving the chenille fabric, a coarser weft is used. The rods 28 are connected to four tappets 27, which give lifts of two different heights to the healds, the latter having independentlyactuated top and bottom staves 4, 5 carrying needles 26 for the warps so that they may be completely separated. The reed 6, 7, Figs. 1 and 2, is also made in two parts which may be separated, so that a chenille carrier 10 mounted on a frame 12 guided by pinions 13 gearing with racks 14 may be drawn from one side of the loom to the other, laying the chenille weft 9, from a can 90 hanging from the carrier 10, in the shed. At least four warp beams 75 are used. The carrier 10 is drawn across the loom by a rope 15, one end of which is passed round and is fastened to a pulley 16, the other end passing over a pulley at the other side of a loom and then being fastened to the pulley 16. The shaft of the bevel-wheel 20, from which the pulley 16 is driven, is provided with two loose pulleys 23 and a fast pulley 22, so that, by means of open and crossed straps, the pulley 16 can be driven in either direction. The strap guides for the pulleys 23 are connected to each of two shafts 24 on each side of the loom, each having a treadle 25. In weaving the chenille portion, the operative on one side depresses the treadle 25, and turns the corresponding shaft 24, and, by means of lever mechanism 36, 35, 33, &c., the upper portion of the reed is separated from the lower, the strap is placed on the fast pulley 22, and the carrier 10 is pulled across the loom, the chenille being laid in the shed between the jaws of a chenille setter 40, Fig. 8, having teeth fitting between the teeth of the reed. The treadle is released, and the reed closes. The operative now adjusts and matches the chenille to the pattern or design, the loom is started, three or more binding-wefts are put in, and then the loom is stopped automatically or by hand, the top healds being in their second or higher positions. The jaws of the chenille setter 40 are meanwhile closed and moved into a vertical position by means of tappets 57 on a shaft 48 driven by chains 56, 53 from the tappet-shaft 3, the jaws being kept raised by tappets 46 acting on bowls 45 on arms 44 carrying supports 42 for the setter. A link 68 connects the supports 42 to an arm 66, and is pulled to the right by a spring 67, a bowl 65 on the arm 66 being then in contact with the smaller diameter of a cam 64, and the jaws are moved so as to position the chenille in the shed correctly. The jaws are then opened by the tappets 57, and drawn down below the shed by the bowls 45 falling on the smaller diameters of the tappets 46, and by the time the three picks have been placed in, the jaws 40 have resumed their original position. The loom is then stopped, the operative depresses the treadle on the opposite side of the loom, and the chenille carrier is drawn back across the loom, when the operations described recommence.
