Abstract
A device for the correct angular positioning of fasteners such as buttons, rivets or the like in the tool of an attachment machine which has a trough-shaped guide rail for these fasteners arranged in front of the tool, the rail having a curved friction lining over at least part of the length of one side thereof and having, on its opposite side, a side wall which is spring-biased in the direction of the friction lining. A swingable slide is associated with this rail and pushes these fasteners forward which are provided with an indexing stop. A finger on the slide touches the indexing stop of the fastener in one position thereof. The pushing surface of the slide is disposed on the longitudinal center line of the feed trough, and the finger is separable from the slide and is arranged laterally of the longitudinal central line.

A device for transportation and correct angular positioning of fasteners such as buttons, rivets or the like in the tool of an attachment machine which has a trough-shaped guide rail defining a feed trough for the fasteners provided with an indexing stop, which is arranged in front of the tool, the rail having a friction lining over at least part of the length of one side thereof and having, on its opposite side, a side wall which is spring-biased in a direction of the friction lining, comprising
- slide means disposed along said rail for pushing forward the fasteners, respectively, along said feed trough, said slide means having a pushing surface therefor, said pushing surface being disposed on a longitudinal center line of the feed trough and adapted to engage said fasteners, respectively,
- stop means for contacting the indexing stop on the fasteners, said stop means comprises a pin arranged on said slide means and laterally of said longitudinal center line,
- said feed trough defines a curve,
- a swing lever being pivotally mounted about a stationary pivot axis and having a free end for swinging substantially along said curve of said feed trough,
- said slide means is arranged at said free end of said swing lever so as to swing substantially along said curve of said feed trough and is adapted to get behind said fasteners for pushing the latter by said pushing surface,
- said pushing surface of said slide means is formed as an abutment surface.
