Abstract: 10,886. Boyer, F. July 27, 1914, [Convention date]. Beat-up motions; lays; picking-motions; pickers and picking-connexions; shuttle boxes; shuttles; shuttle-races.-In a loom for weaving carpets in which knots are formed on vertically arranged warps, means are provided for actuating and guiding a shuttle, and for operating a reed to beat up the weft. The reed 23, Figs. 1 and 4, is mounted between frames 24 fixed by bolts 25 to links 22 pivoted to levers 20 on a shaft 15. The links are guided sideways, as they are moved up and down, by rollers 29 moving between vertical guides 28, Fig. 2, which are adjusted out of the vertical position for the knotting process by means of lever-andcam devices. The shaft 15 is rocked to actuate the reed by a cam-groove formed in a disk 3, Fig. 1, on the main shaft 2, and acting on a roller on a lever 4 on a shaft 5, which is connected by a lever 6, rod 7, two-armed lever 13, 14, link 19, rod 17, and link 18 to a lever on the shaft 15. The rod 7 has a hooked end, which is adapted to engage a cross-pin in the forked end of the arm 13, and is guided between rollers 8 and a link 9, while similar rollers on a parallel link 10 guide a similarly hooked rod a, the arrangement being such that, when weft is to be supplied and beaten up, the rod 7 is engaged with the arm 13, and, when the knotting is to be effected, the rod 7 is disengaged and the rod a is engaged and is operated from a shaft for imparting movement to the knotting- tools in order to move the reed in connexion .therewith. The shuttle 37, Fig. 2, is picked from a shuttle box 36 through an extension box 102 by a leather picker 58. which is slotted to engage a picking-stick 59 held within a picking- lever 60, Fig. 3. This lever is connected by a belt 74 to a lever 73 on a shaft 71, the belt being clutched to the lever 73. A wiper 68 on a shaft driven from the main shaft acts on a 'roller 66 to rock on a shaft 64 having a lever 67, to which is pivoted a rod 77 held up by a spring 79 to contact with the sharp edge of an arm 72 on the shaft 71. One arm 82 of a lever 82, 83, Fig. 1, rests on and depresses the rod 77, and the other arm 83 is connected by a rod 86 to a lever 85 having a sliding pieca 87 resting on a curve 88 on a hub of a disk 52 driven from the shaft 2. When the piece 87 enters a depression in the curve 88, the arm 82 is raised and the rod 77 contacts with the arm 72, so that, when the rod 77 is moved longitudinally by the action of the wiper 68, a shoulder 78 thereon acts on the arm 72 and the picking-stick 59 is actuated to throw the shuttle into the opposite box. During its traverse, the shuttle is guided by plates 90, Figs. 2 and 4, on bars 89 situated in front of and behind the warps and supported by arms 91, pivoted on pins 92 on cross-heads 96, which are moved up by rods 97, actuated by a cam-groove and lever mechanism, when the shuttle is to be picked, so that the arms 91, which have rollers 93 engaging cam-grooves 94, move the plates 90 between the shed warps x to form a race for the shuttle. The plates are moved down again before the reed beats up the weft. Instead of using the plates 90, the shuttle 103, Fig. 10, may have the cross-section shown, almost filling the space between the warps, which guide the shuttle.
