IPC: D05B57/02
Filed: 1921-04-21
Abstract: 182,958. Fairweather, W., (Singer Manufacturing Co.). April 21, 1921. Button-hole sewing-machines; loop-stitching.- A looper having endwise and sidewise movements is actuated by a member of a toggle device one element of which is connected to the looper by an independent link. The toggle device comprises a rocking member or elbow-lever 118, Figs. 5 and 7 connected to a pivotally mounted sleeve 109 by a link 115, and also by a link 126 engaging ball-studs 125, 127 to a crank 124 projecting from a shaft 110 carrying the looper s and rotatably mounted in the sleeve 109. The pivot stud 107 of a swinging arm 108 carrying the tubular socket 109 is journaled in a boss 106 of a turret 79. The elbow-lever 118 is pivotally mounted on a stud 119 secured in a boss 120 on the turret. The lever 118 is also connected by a link 122 to a cross head 86 having a vertical reciprocatory movement. The continued movement of the elbow-lever 118 during the dwell of the vibratory movement of the rocking arm 108 produces an oscillatory movement of the pin 110 and a lateral swinging movement of the looper to bring part of the spreader blade immediately behind its shoulder close to the path of the lower needle to hold the loop for the passage of the latter. The needle and looper mechanism are actuated by a shaft 14 which drives the upper needle through a pitman. A crank plate 57 on the shaft 14 carries crank pins 58, 59 of which the pin 58 enters the boss of a link 61 carrying a stud 62 and the pin 59 enters a boss 63 at one side of an eccentric strap 64 surrounding a boss 65 which pivotally receives the stud 62. The boss 65 is formed on the end of a pitman 67 pivotally connected at its upper end by a pin 71 to a sleeve 70, the end of the pin carrying a roller which engages a guide way 72 in the casing 2. The rotary turret 79 is mounted on a ball race 75 in the casing 2 and from it depends a shaft 80 journaled in a bushing 81 mounted in the casing. The shaft 80 has secured thereto an inclined crank arm for rotating the turret. A tubular actuating rod 85 loosely surrounding the shaft 80 carries the cross head 86 a guide pin 87 on which enters an aperture 88 in the turret, Figs. 5, 7 and 10. The sleeve 70 fits loosely on the rod and communicates its reciprocation thereto by reason of confinement between the cross head and a thrust collar 89. The turret has at one side a boss 90 with a slightly inclined bearing to receive the fulcrum-stud 91 of the lower needle arm 92 to which is clamped the curved needle 94. The arm 92 is connected by a pitman 96 to the cross head 86 the vertical reciprocations of which cause an oscillation of the needle 94 in a circular path in a plane slightly inclined to the upper needle. The needle 94 passes through a U-shaped slot in a needle throat 100 off-set from a block 101, a tongue 103 serving as a loop detainer for the upper thread. A groove round the needle-throat receives a cord C, Fig. 22 which is led to the needle aperture through a transverse hole 105. Specification 185,711 is referred to.
