WEAVING-Loom, a machine for weaving cloth, silk, &c. by raising the threads of the warp in order to throw in the shoot, and strike it close. Of these there are various kinds, distinguished by the different sorts of cloths, stuffs, silks, &c. in which they are employed; and which are chiefly distinguished by the number and variety of the threads they raise in order to work the warp, either plain or in figures, by making more or less of the woof or shoot appear through the warp. In order to give a general idea of weaving, we shall here describe the parts of the common weaver's loom. See plate CCCXI. fig. 2. in which 9, 9, are the loom-poles. 10. The cross-bars. 11. The batten; which serves to strike in, and close more or less the threads of the woof. 12. The cap of the batten, or a long bar, which the weaver takes hold of in one hand and then in the other. 13. The block, or under part of the same, containing the reed within the lower bar. 14. The cross-piece, or burdon and pin, which helps to make the batten moveable. 15. The gallows; a piece of wood suspending the pulley on which the cord moves that is tied to the two lams. 16. The breast-bar; a flat square piece of wood, with an opening in it to let the stuff through which is rolled on the knee-roll. 17. The cane-roll, which the warp is turned on at the other end of the loom. 18. The reed. 20. Pulleys, upon which the cords roll that are fastened to the lams. 21. The tumbler; which is a cord that passes from one lam to the other over the pulley 20, and causes the working of the lams by its ascending and descending. 22. The muffle in which the pulley acts. 23. A skain, or leash, cut into proper lengths, to mend the leashes of the harness that happen to break. 24. A bobbin of the warp, to mend the threads of the warp that occasionally break. 25. Lizier-thread, to mend those of the lizier that happen to break; and which, especially in cloth, are very different from the warp. 26. The box to hold the quills. 28. The foot-bar. 29. The trundles, or moveable bars, tied with two cords to the lower virgee of each lam. When the foot presses a treadle, the lam that is fastened to it sinks, and the other rises by the help of the tumbler. 30. The foot-step. 31. The temple; a double flat ruler, having small teeth at the extremities; it may be lengthened or shortened by the help of a catch that is in one of the rulers, and introduced in a groove in the other ruler. The teeth in the extremities are fastened in the lizier of the work, by which means it is kept of an equal breadth; and as the work advances the temple is moved forwards. 32. The shuttle seen in front and profile. 33. The knee-roll, on which the work is rolled as it is wove. 34. The tantow; an iron lever to turn the knee-roll. 35. The reed seen separate.
