Abstract
222,691. Dicker, S. G. S., (Lock-Edge Machine Corporation). Nov. 5, 1923. Multiple - needle machines; needle - guides; presser-bars; surface threads, attaching.-In a post machine for sewing gloves twin needles 89, 90 are sweated into or clamped in holes in a needle-bar 85, Fig. 13, which is pivoted on a sleeve 77 slidingly mounted on a post 76, Fig. 1. The needle-bar is vertically reciprocated by a bellcrank 100, 97 from a cam 99, Fig. 2, on the main shaft 55. The needle-bar is held in place by a spring 80. The needles co-operate with rotary shutters 110 which are actuated by shuttle-drivers 152 on shafts 116 carrying a pinion 119 driven by an adjustable rack-bar 128, which is actuated through a lever 125 from an eccentric-actuated bar 124. The shuttle-races are formed bv horns 149, pivoted latch-members 157, which leave a cast-off gap 174, Fig. 4, and partition walls 140, 141, Fig. 6, together with the presser-bar 142. Loopers 196, 197, Fig. 4, for surface threads are pivoted at 209 to a member 213 pivoted at 214, Fig. 2, to the frame. The loopers are connected by a toggle 199 having a pin-and-slot connection with a bell-crank 194, 188 which is in turn adjustably connected to a bell-crank 191, 207. The bell-crank 191, 207 is actuated bv a cam on a shaft 204 having a one-to-two gearing with the main shaft 55. Thus the loopers cross once for each stitch. The member 213, Fig. 1, is oscillated through a rod connection with a camactuated bell-crank 183. As the needles emerge from the post the loopers are in front of them in the direction of feed; as the needles penetrate the fabric, the loopers move backward, cross each other, and then move forward again to hold the threads tight around the needles. The needlethreads 240, 241 are guided from spools 13, 14, Fig. 1, to tensions 232, Fig. 2, below the bedplate, are crossed over a post 249 on their way to a cam-actuated take-up lever 227 whence they are guided through a hole and a groove on the needle-bar to the needles. The surface threads pass from spools 15 to tensions 251, 254, Fig. 1, through guide-eyes 257, Fig. 4, on the loopers to the looper-noses. The presser-bar carries a needle-guiding lug 170 which co-operates with a similar lug on a spacing-member 27, Fig. 13, in the post. The presser-bar 142 has an arm carrying a roller 263, Fig. 1, which can be raised against an adjustable spring 265 by a cam 262 on a hand-lever 260. Feed by dogs. - A feed-bar 29 is slidingly pivoted at 32 and is cut away at 33 to clear the member 27. A lug 34, Fig. 1, on the bottom of the feed-bar is linked to a rod 38, which is spring- pressed to the. right, which carries an adjustable thimble 44 and which is reciprocated from a camactuated bell-crank 45, 50. A stirrup 60 on a lever 57 engages under the lug 34 to raise and lower the feed-bar when the lever 57 is oscillated through a link 62 adjustably connected to a camactuated lever 64. The feed-bar 29 acts as a guide for the needle-bar. Work-supports.-The post 20 is formed of two parts 21, the upper front ends of which are L- shaped so as to form a flat front face for the post and to have a vertical slot therein to facilitate threading the needles. A spacing-member 27, Fig. 13, T-shaped in cross-section holds the parts 21 together.
