Abstract: 9085. Lake, H. H., [Whitcher, F. W.]. April 17. Laces.-Laces and other articles of tubular fabrics are cut at the ends, or to length, and the ends turned in, cemented, and then pressed to form tags, by the apparatus shown. The lace or fabric i, Fig. 1, which is laid by hand or fed from a reel; is held at one end by a device A, and at another point to the right by a device B. The device A consists of grippers 10, 11, Fig. 7, which slide in a sliding frame 12 having a slit 13 in which the fabric rests between the heads 14, 15 of the grippers. On the frame of the machine is a fixed cutter 28, and on the frame 12 a cutter 29, so that on the frame 12 being slid by suitable cam and-lever mechanism, the end or a length of the fabric will be cut. The gripper 11 is also actuated by cam-and-lever mechanism, and the gripper 10 has a spring connexion with the frame 12. The device B consists of a gripper 37, Fig. 19, pivoted to the bracket 34 attached to the frame 12. The gripper interlocks with a cam 40 actuated by a spring 42, to secure the fabric when, by the movement of the frame 12, the cam escapes from the stop 421. By the movement of the devices A, B, the fabric is carried to the position in which the end is turned in. The fabric then rests in the centre of a chuck C, Figs. 3 and 18, having radial slots to receive sliding-grippers 61, which are pressed to the fabric by springs 65, 66. The grippers also make contact with a cam 70 by which they are actuated. While the fabric is in position, a spear 43, Figs. 1 and 5, attached to a slide 74, is caused to enter the open end. Clips 44, attached also to the slide 74, are compressed to grip the end of the fabric behind the shoulder of the spear 43, by means of pins 78 on a second slide. The spear is then moved forward and the gripped end is turned inwards, the grippers 61 preventing longitudinal movement of the fabric. The clips 44 are released before the withdrawal of the spur so as not to interfere with the turnedin end. This turning-in device, consisting of the spear 43 and clips 44, may be used independently of the rest of the machine. The fabric is next transferred to a device by which cement or composition is supplied to the turned-in end. The carrier or transferring-mechanism E, Figs. 3 and 20, consists of an arm 96, mounted on a rotary and longitudinally-movable shaft or rod 99, the arm having pivoted thereto a gripper 98, integral with a cam 602, operated by springs 600, 604. When the shaft 99 is rotated, the spring 600 engages with a pin on the device B, thus liberating the cam 602, which is rotated by the spring 604, and is causing the gripper 98 to close on the fabric, which is at the same time released by the gripper of the device B. The shaft 99 is then moved longitudinally to withdraw the fabric from the turning-in device, and it is next rotated to bring the fabric before the cementing-device G. This consists of a pump cylinder 112, Fig. 6, having a tip 113 which enters the end of the fabric, the cylinder moving on a fixed piston 114 having at the forward end a wire 115 which fits the tip 113. The cement is supplied from a can 109 by a pipe 111. The amount of cement deposited is regulated by adjusting the position of the piston. The cement being thus injected into the end of the fabric, the latter is carried to a die F, Fig. 3, by which the cemented end is compressed. The die consists of a bottom member 138 integral with the block 130, a top member 131, and a side member or guide 132 which assists in partitioning the fabric. The guide 132 and die 131 are actuated by cam-and-lever mechanism. When the dies have closed on the fabric, the carrier E is automatically opened. The carrier is moved longitudinally by the cam lever 101, Fig. 1, which is connected with the shaft 99 by a link 103 and a ball-and-socket joint 104, and rotary movement is imparted by another cam lever connected by a link to an arm on the shaft 99.
