A feeding mechanism for feeding material to a machine comprising a supporting structure, a drive roll rotatably mounted on the supporting structure, a second roll rotatably mounted on the supporting structure, a drive lever mounted for pivotal movement in both directions about a pivotal axis, a one-way clutch for coupling the drive lever to the drive roll, an adjustable stop for limiting the pivotal movement of the drive lever in one direction, and a resilient member for driving the drive lever in said one direction.
An apparatus for inserting a socket into a printed circuit board comprising a supporting structure, first and second resilient fingers attached to the supporting structure, and a socket holding mechanism. The resilient fingers are adapted to receive and releasably retain a socket therebetween at a socket retaining station. The socket holding mechanism is mounted on the supporting structure for movement from a first position on the side of the socket retaining station remote from the printed circuit board toward the printed circuit board along a path which passes through the socket retaining station and between the resilient fingers. As the socket holding mechanism passes through the socket retaining station, the socket is removed from the resilient fingers and coupled to such mechanism so the socket holding mechanism can move the socket to the circuit board.
