Abstract: A transfer mechanism has a tool mounting surface movable in a generally inverted U-shaped path back and forth between spaced stations thereby making the mechanism useful, for example, as part of a pick and place device for picking up articles one at a time, or in groups at a time, from one first station and placing them at the other station. The U-shaped motion is achieved by a first body supported on a base for movement along a first axis and a second body supported on the first body for movement relative thereto about a second axis perpendicular to the first axis. The movement of the two bodies along their respective axes is achieved by a single oscillating crank arm engageable with both bodies in such a manner as to obtain a smooth gentle acceleration and deceleration of the two bodies with a minimum amount of driving force and capable of providing a short cycle time if desired.

Abstract: An apparatus for orienting and feeding axially elongated articles has a feeder bowl which includes a helical ramp surface which terminates at the upper edge of the bowl. An annular ring supported for rotation around an upper portion of the feeder bowl has an upwardly facing article supporting surface contiguous with a terminal portion of the ramp surface to receive articles therefrom. An annular baffle disposed above the ring and in coaxial alignment with it coacts with the ring to successively release articles from the ring to a guide conveyor which directs the articles tangentially away from the ring. Separate independent drive mechanisms are provided for vibrating the feeder bowl and rotating the ring to enable the feeder bowl to operate intermittently to discharge articles onto the ring which may operate continuously.
