Abstract: 472,197. Sewing-machines. NICOLAY, K. Sept. 12, 1936, No. 24916. [Class 112] A hand-guided sewing-machine for sewing tickets to pieces of materials or for tacking articles together in pairs comprises a pistolshaped carrier for the sewing and threadcutting devices, operated by a flexible cable driven from a distance, the sewing and thread - cutting device being set in motion by pulling a trigger. The device is held in the hand by a stock 29 which houses the thread supply 30 and tension discs 31. The actuating shaft 3 is driven by the flexible rotating cable 38. The arm 2 has a wedge shaped end for entering between pieces of fabric in piles. The work to be sewed is placed between the arm 8 and fixed resilient arm 9. The cable 38 rotates the shaft 3 to reciprocate the sewing arm 6 carrying the needle 5 by an eccentric rod 4. The looper 7 is carried at the end of the shaft 3, Fig. 2. At each rotation of the shaft 3 the lever arm 11, by the aid of the pawl 12, rotates the wheel 13 one tooth, causing the arm 8 to move sidewise about its pivot 19 one step to feed the work. This is continued till a large tooth 15 has slid up the length of a corresponding tooth 14 on the boss of the wheel carrying the teeth 13, Fig. 3, when the, tooth 15 snaps past, restoring the arm 8 to original position, a predetermined number of stitches having thus been made. The trigger 23 is then pulled to actuate the thread cutters 28, Fig. 2, by levers 26, 27. A spur 34 on the trigger enters a recess in the stock 29 to move a lever 35 to separate the tension discs 31 to release the thread to facilitate pulling off sufficient to start the next group of stitches, after cutting. Driving. The flexible cable 38 is rotated by a shaft 50, Fig. 6, which is rotated by a gear 49 to which it is connected by friction clutch discs 51, 52. The gear 49 is rotated by a gear 48 rotated in turn by a gear 46 which is turned by a rack 45 reciprocated by a cable 44 and treadle mechanism. As the cable 44 is pulled down by the treadle, it moves the plate 58 sideways to displace the lever 55 to cause the clutch discs 51, 52 to engage. When the stitches have been made and pedalling ceases, the lever 55 swings back to release the clutch discs. The rack is restored to initial position by a coil spring 53. If the cable 38 is rotated by an electric motor, a friction clutch 65, 66, Fig. 10 is provided on the hand sewing device. This is engaged to effect sewing and disengaged after sewing by a rod 87 connected to the trigger and having a hook end engaging a slide member 88.
