  • Patent number: 4633995
    Abstract: A chute for use with an electromagnetically vibratable parts feeder has an inlet end attached to a bowl tangentially thereto and an outlet end remote from the inlet end. A leaf spring assembly is disposed below the chute and attached thereto adjacent to the outlet end. The leaf spring assembly is inclined at an angle to the chute, and comprises a pair of parallel spaced leaf springs or a sole leaf spring. Each of the leaf springs has an upper end coupled to the chute and a lower end adapted for attachment to a stationary base such as a machine base. The upper end is located more closely than the lower end to the outlet end of the chute. When the bowl is electromagnetically vibrated in circular back-and-forth movements, the chute is reciprocably moved back and forth to cause parts to move forward therealong due to inertia.
