28,089. Buckler, J. Dec. 22. Looms, pile-forming in; shedding-motions.-In looms for weaving pile fabrics in which pile loops are formed over longitudinal wires, the frames which support the pile wires and the healds for the pile warps are arranged to have no transverse movement, the pile warps being carried over the pile wires by a reciprocating comb The flat metal supports 14 for the blades 24, which carry the pile wires 15, are attached at their upper ends to a transverse bar 17, and the lower ends extend lossely through openings in a transverse bar 20, and have weights 23 attached to them. The supports 14 have offsets 14', Fig. 1, arranged relatively to each other to form clear spaces on each side of the upper end of each blade 24, which is made separate from, and is secured at its lower end to, its support. The blades 24 are alternately short and long, so that the pile wires 15, which are pivoted in loops formed on the upper ends of the blades, extend in two different planes. The wires 15 are made of flat metal and are tapered, the extreme pointed ends being made separate from, and pivoted to, the main portions. The wires may be made of round flexible wire rigidly attached to the blades. To carry the pile warps 34 over the wires 15, a transverse comb 27 is employed, which is mounted on crank-arms 28 fixed to vertical rockshafts 30, to one of which a crank-arm 33 is fixed. The arm 33 is oscillated by suitable connection with a driven part of the loom, so that the comb 27 is reciprocated in the direction of its length at the proper times. The lower ends of the teeth 27<1> of the comb extend down a little below the upper ends of the lower series of blades 24. Instead of the comb, a device consisting of a series of pivoted levers, having their upper ends pivoted to a transverse reciprocating bar, may be used. The weighted heald cords 36 for the pile warps extend through holes in a transverse bar 35, which is moved up and down by chains and links connected to levers on a rock-shaft. The shaft is rocked by a crank-arm, a link, and a pivoted lever operated by a suitable grooved cam. The bar 35 may be moved into three different positions, so that the pile warps are shed in three planes. When in the lowest plane, the pile warps pass under the weft, in the middle plane they pass over the weft, and when raised to the highest plane they pass between the teeth of the comb 27, by which they are carried over the pile wires 15. When a plain pile fabric is to be woven, the pile warps are operated by the bar 35 only, but when two or more sets of pile warps are used, the selected pile warps are raised into the highest plane by jacquard mechanism. In order that the pile warps not selected may not interfere with the pile warps which are moved across the pile wires, they are raised into the highest plane by the bar 35 at regular intervals, preferably at every fourth pick, and are moved down on the proper side of the blades 24. The bar 17, to which the supports 14 are attached, and the comb 27 may be reciprocated vertically, the pile wires, preferably made of flexible wire, being carried above and below the plane of the woven fabric. Two binder warps and a stuffer warp are operated by heald frames 8, 9, 10 in the usual manner.
