  • Patent number: 5263627
    Abstract: A machine (1) for attaching buttons, rivets or the like, preferably to articles of clothing, which buttons, rivets or the like consist of an upper part (124, 125) and a lower part (67, 68) which are fed to an upper tool (9) and lower tool (10) from magazines and are brought into form-locked connection with each other with the interposition of the material (167) by the stroke of a ram (140); in order to optimize the use of different button parts, it is proposed that the upper tool (9) and the lower tool (10) be arranged opposite each other, lying in each case one behind the other in a row on the upper (51) and lower (48) arms of a U-shaped carriage (30) by the positioning of which the upper tool (9), which is to be placed in action in each case, enters into coupling position with respect to the ram (140).

  • Patent number: 5181300
    Abstract: The invention relates to a waistband fastener, especially for trousers, skirts or the like, comprising a latch rail (1) fixed to a waistband portion (A) and bearing a plurality of sawtooth-like teeth (3), on which latch rail a slider (2) connected to the other waistband portion (B) is guided in an adjustable and latchable manner. To enable a simple and advantageous handling and operation of the fastener, a latch finger (12) can be selectively brought into and out of engagement with the teeth of the latch rail by means of a transverse shifting of the slider away from and toward the latch rail. In the first case, the latch finger simply slides over the teeth, by virtue of riding up on their sloping faces, when the slider is moved in one direction (arrow y) along the latch rail. In the other case, the latch finger is shifted out of the tooth gaps (4) and clear of the teeth to permit movement of the slider in the opposite direction.
