Abstract: 27,535. Marks, G. C., [Goldman, G.]. Dec. 16. Padding; cutting- out.-Relates to machines for cutting garment pads &c. from felt such as is described in Specification No. 2680, A.D.1904,[Abridgment Class Fabrics, Dressing &c.]. Fig. 2 shows theapparatus combined with the skiving-machine described in Specification No. 27,534, A.D. 1904. The material passes from the pattern roller, which may have two crests 18 and troughs 19, past the reciprocating skiving - knife 22, which cuts out two channels in the material at each revolution of the roller, and then proceeds between continuously-rotated feedrollers 23, 24 to intermittently-rotated feedrollers on the shafts a, b, these shafts being vertically adjustable, even when the machine is at work, by means of a hand-operated ratchet-wheel 35, pawl 36, pinion 33, and rack 30. The shaft a is spring-mounted for self -adjustment to the thickness of material. The shafts a, b are connected by spur gearing 40, 41, and the shaft b carries an idle sprocket-wheel rotated in unison with the feedrollers 23, 24 by a chain 52. The rollers on the shafts a, b are intermittently operated by the pulley 42, rotated by a belt 43 driven from a pulley wbich is attached to one member of an ordinary clutch mechanism operated by the draw-rod 94. After each intermittent rotation of the pulley 42, a tooth on the continuously-rotating sprocket-wheel leaves a similar engaging tooth on the pulley until it is caught up again by the latter tooth when the pulley rotates. By this means, any slack in the material 27 is taken up, and undue tension prevented by the slipping of the pulley when engagement of the teeth takes place. The material passes downwards behind the pivoted apron 45, the belt 48 serving as a guide, and when it comes opposite the die cutter 2 the positions of the shafts a, bare adjusted so as to bring the thick portion 27 opposite a cutter blade in the middle of the cutter. The platen is driven forwards by the disengagement of a catch shoulder on the lever arm 62 from a shoulder in a slot of the forked guide 71, and by the consequent transference of a belt 17, by a spring 58, from a loose pulley 16 to a fast pulley, which drives pinions 13, gearing with toothed wheels 10. This advance of the platen forces forward the swinging apron 45 against the action of the spring 120, which bears against the arms 121, 122 of a bell-crank lever connected to the apron. By the engagement of the arched rib 97 with a lever 117 connected to a link 115, which in turn operates a roller 113 and thereby links 112, 110, the pushers 106 eject the pads from the hollow die 2 as they are cut. The disengagement of the catch shoulders, mentioned above, takes places twice in each revolution of the roller 18 by the action of pins 79 on one end of a pivoted lever 74, the other end being connected to a swinging link 72 guided in the forked guide 71 and held against the arm 62 by a spring 77. As the arm 117 releases itself from the rib 97, a lug 85 acts, by means of an arm 86 and one end of a bell crank 81, to stop the machine by the action of the spring 87. Meanwhile, the roller 80 has forced back the lever 65 and the belt shifter against the action of the spring 58, and the catch shoulders have been brought into engagement. As the belt shifter moves, a cam-shaped portion thereon forces the lever 90 outwards at its lower end and inwards at the other, so as to bring the roller 96 on the bell crank 94 into the path of the rib 97, which acts through the bell crank to pull down the draw-rod 94 and bring the clutch members into engagement to start the feed-rollers on the shaft a, b.
