<p>A chute (20) for use with an electromagnetically vibratable parts feeder (10) has an inlet end (22) attached to a bowl (11) tangentially thereto and an outlet end (26) remote from the inlet end (22). A leaf spring assembly (25) is disposed below the chute 20 and attached thereto adjacent to the outlet end (26). The leaf spring assembly (25) is inclined at an angle to the chute (20), and comprises a pair of parallel spaced leaf springs (30, 31). Each of the leaf springs (30, 31) has an upper end (32, 33) coupled to the chute (20) and a lower end (36, 37) adapted for attachment to a stationary base such as a machine base. The upper end (32, 33) is located more closely than the lower end (36, 37) to the outlet end (22) of the chute (20). When the bowl (11) is electromagnetically vibrated in circular back-and-forth movements, the chute (20) is reciprocably moved back and forth to cause parts (H) to move forward therealong due to inertia.</p> |
