Abstract: 854. Mills, B. J. B., [Soc. Anon. de Broderie Automatique]. Jan. 16. Cards, punching.-Consists of a machine for perforating the paper used in the working of the jacquard in the automatic embroidery machine described in Specification No. 7393, A.D. 1901, [Abridgment Class Sewing &c.]. The apparatus, Fig. 1, comprises two parts, a reading-apparatus and the perforator. In the reading-apparatus, a horizontal rod d is guided by uprights f to move vertically in front of a board b on which the embroidery design is drawn. A carriage g having a point h can be moved horizontally on the rod d, and the point can thus be caused to follow the contour of the design. The rod is supported by two metallic ribbons j<1>, j<2>, which are suitably guided and unite in a single perforated ribbon j. This ribbon passes round a toothed pulley 33 on the axle of a cylinder a of the perforator, and the weight of the rod d is balanced by a weight k. To the carriage g are attached the two ends of a ribbon l, which is suitably guided and tensioned, and passes round a second toothed pulley 33 on the axle of a cylinder c of the perforator. The vertical and horizontal movements of the point h are thus transmitted in extent and direction to the cylinders a, c respectively. The cylinders a, c of the perforator are provided with suitably-arranged holes, into which the ends of fingers 20, Fig. 3, may enter. The paper x to be perforated is supplied from an exterior roller, passes through the perforator v, over a drawing-roller y, and is wound upon a receiving-roller z. A shaft 10 is provided with a loose driven pulley, which is clutched to the shaft when a ribbon u, Fig. 1, is drawn upwards by mechanical means r operated by a ribbon q when the latter is pressed against by a finger e on a rod n turned by hand. The clutch between the shaft 10 and its pulley is automatically disconnected when the shaft has made a complete revolution. A cam 13 on the shaft 10 operates levers 14 and pawls 15, 16 by which the rollers y, z are rotated to draw forward the paper x. The levers 14 also act through connecting-rods upon raising- levers 18, which, at the required time, remove the fingers 20 from the cylinders a, c. When the operative has brought the point h to the required part of the design, the fingers 20 may not be exactly opposite the corresponding holes in the cylinders a, c, and the latter are correctly positioned by means of attached ratchet-wheels, which are operated upon by pawls actuated through suitable link-work by a cam on the shaft 10. The cylinders are thus in the correct position when the fingers 20 are freed from the raising-levers 18 and come to bear on the surface of the cylinders. A single finger 20 of each series enters a hole in its cylinder, and causes the head of a corresponding rod 34 to be pushed above a punch in the perforator. The perforator is operated by levers 12 rocked by a cam 11 on the shaft 10, and at each stroke other punches form on the edges of the paper the holes which serve to draw forward the paper by the roller y and in the jacquard mechanism. Other fingers 35 can, at the will of the operative, operate special punches of any desired number. These fingers are placed in action by ribbons t, which are drawn upwards by mechanical means s, Fig. 1, ribbons p, fingers i, and rods o, of which there may be any required number, in the same manner as the ribbons u. The ribbons t operate cylinders 36, Fig. 3, furnished with grooves which come in front of the nibs of the fingers 35. The holes formed by these punches determine accessory functions of the embroidery machine, such as the stoppage of the machine, the tension of the threads, &c.
