ABSTRACT:
The apparatus includes a plurality of bobbin transporting members for transporting bobbins from supply sources to belt-like conveyors extending along opposite sides of a spinning machine with which the apparatus is associated. During normal operation of the apparatus, oscillatorily-movable drive means imparts continuous, synchronous oscillatory movement to the bobbin transporting members. The stop-motion promptly halts operation of the apparatus in response to significant variation in regular oscillatory movement of any of the bobbin transporting members, which variation might be caused by a bobbin-jam within the apparatus. In the preferred embodiment of the invention, the various switch elements of the stop-motion circuit are all mounted by a single bracket member for convenient positional adjustment and installation in an area of the apparatus distal from the paths of travel of the bobbins transported through the apparatus.
