Abstract: 123,061. Batchelder, F. R. Feb. 6, 1918, [Concention date]. Pattern surfaces.-In building up pattern or control chains for looms &c., the pattern-indicating elements, such as rolls and spacer-sleeves, arc assembled in a row in pattern relationship, their apertures are alined, any necessary corrections are made, and a carrier rod or bar is inserted through the alined apertures. In apparatus for thus building up the chains, the rolls 1, Fig. 1, and sleeves 2 are placed in series of hoppers 16, 17 extending across the apparatus, and each of a series of feeder-slides 18 co-operates with a pair of the hoppers. Each slide 18 is connected to one of a series of levers 22 loosely munted on a sleeve 23 surrounding a rock-shaft 24, and the lower end of each lever 22 is connected to a key or slide 10 provided with a finger-piece 11. A cam-slot 12 in each key is engaged by a pin 13 on a slidable support 6 provided with a notched upper end. When the parts are in the positions shown, a roll 1 and a sleeve 2 enter pockets 18<a>, 18<b> in the slide 18, and the finger-pieces 11 are successively moved forwards or backwards bv hand, in accordance with the pattern arrangement of rolls and sleeves for a row of the chain, to cause the slides 18 to be moved to deliver the rolls or sleeves through an opening 21 on to runways 20a, whence they fall on to the upper ends of the supports 6. At the same time, the movement of those keys 10 that are moved rearwards causes their cam-slots 12 to raise the supports which are to receive sleeves 2, so that the apertures 1<a>, 2<a> of the rolls and sleeves are alined. The cam-slots 12 have rearward elongations to allow the keys to be moved forwards without affecting the supports that are to receive rolls. The apertures having been alined as shown in Fig. 8<a>, any necessary correction is made and a carrier rod 3 is inserted through the apertures by hand; this may be facilitated by the provision of a trough extending out to one side of the apparatus, the rod 3 being laid in the trough and moved along it by hand or bv a hand-operated slide. The rod 3 may be a rod of the pattern chain or a transfer rod, and the rolls and sleeves may be held temporarily in position thereon by a spring clip 131, Fig 18, of which one or both ends 14 are adapted to enter an aperture in the end of the rod. A tag 15 numbered to indicate the row of the pattern may be attached to the clip. Preferably evening-devices are provided for restoring the slides 18 and the supports 6 to their normal positions after an assembling operation, and, for this purpose, bars 28, 29 on opposite sides of the levers 22 are carried by arms 30, 31 secured to the ends of the sleeve 23 and rock-shaft 24, further arms 33, 32 being secured to the sleeve and shaft and being connected by links 35, 34 to a head 36 on a rod 37 secured to a treadle 38. When the treadle is depressed against the action of a spring 39, the bars 28, 29 approach one another and move the levers 22 to their intermediate position, thus returning the slides 18 and supports to their normal positions. Partitions 40 may be provided between the runways 20<a>, and these partitions are extended over the supports 6 and have notches 40<a> for the passage of the carrier rod 3. The selective feeding-devices may be dispensed with and the rolls and sleeves placed by hand on the supports 6, either when all the supports are raised or lowered or when they have been positioned in accordance with whether they are to receive rolls or sleeves.
