(57) A parts supplying apparatus (10) includes a dropper mechanism (13) associated with
a chute (11) for delivering fastener parts one at a time from the chute (11) to a
loading station (S) in a fastener assembling and setting machine. The dropper mechanism
(13) includes a first bell crank (22) having a stopper portion (28) projectable into
a guide track (19) inthe chute (11) to prevent a leading fastener part (P1 ) from
sliding downwardly therebeyond, a second bell crank (23) having a presser portion
(33) disposed upstream of the stopper portion (28) and projectable into the guide
track (19) for pressing the next succeeding fastener part (P2) against the chute (11).
and a reciprocable actuating rod (24) operatively connected with the first and second
bell cranks (22, 23) for oscillating them to move the stopper portion (28) and the
presser portion (33) to ahemately project into and retract from the guide track (19).
The apparatus (11) also includes a posture-control block (14) disposed on the loading
station (S) for introducing the fastener part (P) to the loading station (S) in a
