Abstract: The pedal binding makes it possible separably to couple a shoe to a bicycle pedal rotatable about a pedal spindle and comprises a pedal side coupling part which forms a tread area and, adapted to be fitted onto the tread area, a shoe side coupling part. The coupling parts are separably locked together via catch members disposed on mutually facing surfaces of bifurcated arms of the pedal side coupling part on the one hand and bifurcated arms of the shoe side coupling part on the other. Such a snap-action connection is simple and operationally reliable. Mutually associated pairs of sloping thrust faces on the coupling parts assist the separation of the locked joint upon relative tilting movements of the two coupling parts.

Abstract: A workpiece is held down against a support surface by a holddown foot. Then a feed foot is brought into engagement with this workpiece with its displacement speed decreasing continuously and uniformly until the feed foot comes to a stop against the workpiece, pressing it against the support surface. Thereafter the holddown foot is raised away from the workpiece and the feed foot slides the workpiece a predetermined distance along the surface toward the sewing station. The holddown foot then is brought into engagement with the workpiece on the surface, again with its speed decreasing uniformly and continuously until it comes to a stop on the workpiece. The feedfoot is lifted away from the workpiece and brought back into a position to advance it again.
