Abstract: 7077. Lake, H. W., [Bek, E. G., (Firm of)]. March 21. Making metal fabrics; coiling; winding and reeling; shearing-adjuncts.-In a machine for making metal ring fabrics, the wire 10 is coiled on a mandrel 7 which is rotated from the main shaft 1 by a crank 3, connecting-rod 4, and toothed sector 5, which engages a wheel 6 connected to the mandrel shaft 8 by detents so that the mandrel may make a complete rotation during one stroke of the rod 4 and remain stationary during the return stroke. The adjustable guide-arms 11 for regulating the pitch of the coils are periodicallv moved forward by an eccentric 12 to bring the wire opposite the pincers 17, into which a coil is pressed by a slide 20 operated by a cam 18 and lever 19. The pincers are mounted in a pivoted holder 23, the pivot 16 of which is on a line passing through the centre of the coil. The holder is mounted in a slide which is moved longitudinally in a transverse slide 21 by a cam-operated lever 28. The pincers have a fixed and movable jaw, the movable jaw being pressed outwards by a spring 24 and having a projecting pin 25 which, during the motion of the pincers towards the coil, engages a stop 26 so as to open the jaws. During the first part of the return motion of the holder 23, the pincers close on a single coil which is at the same time severed from the rest of the wire by a knife, nippers, &c., or by a saw 31, Fig. 3, rotated by a pulley 30 and mounted on a slide which is reciprocated by a lever and cam 32. The holder is then moved to the right by the lever 28 and the slide 21 traversed by a cam 35 until the nose 37 contacts with a slidable catch 39 operated by an eccentric 38, when the holder is turned on its pivot 16 so that the joint of the link is brought from a vertical position into an horizontal position. The link in this position is moved so that its ends take over the space between two partly overlapping rings, Fig. 9, of the fabric 41 held in jaws 40, Fig. 3, the space having been previously widened by a pointed tool 83 reciprocated by a lever 85 and cam 84, Fig. 2. The pincer-holder is then returned to its horizontal position, the link being threaded through the openings, and the ends again assuming a vertical position, Fig. 11. The pivoted jaw 44 of the pliers, Fig. 14, which are mounted on a reciprocating slide is then operated by an eccentric 48, rod 49, and follower 50, to close the ends of the link. The fabric 41, which is held in jaws 40 and carried over a drum 52 mounted on a slide, is fed along by the space of one link, when the pincers 17, 44 have been released, by a rack 54 and pinion 55 on a shaft 56, which carries a clutch sleeve 57, engaging one or other of the loose sleeves 58, 59 according to the direction of feed of the slide. The sleeves 58, 59 are fed intermittently by ratchet-wheels and pawl levers 60, 61 and oscillated by eccentrics 62, 63. At the ends of the traverse of the slide inclined planes 64, 65 engage rods 68, 69 so as to reverse the clutch 57. When a row of rings is completed the pin drum is rotated the space of a row by an eccentrically operated pawl lever 80 engaging a loose ratchet-wheel 77 which carries a disk 76 provided with an adjustable pin which oscillates a lever 74 operating a pawl 71 on the drum shaft. The lever 74 is released from the pin by being moved laterally on a fixed inclined plane 82 and is then returned by a spring.
