Spring connection mechanism for vibratory feeders

A vibratory conveying apparatus, comprising:

• a base member;
• a vibratory exciter supported on said base member;
• a vibratory output member that is vibrated with respect to said base member by said vibratory exciter;
• a first bar extending longitudinally of said base member between a base end and a distal end thereof and connected at said base end thereof to said base member;
• a second bar extending longitudinally of said base member between a base end and a distal end thereof and connected at said base end thereof to said base member;
• a leaf spring arranged across said base member and connected to distal ends of said first and second bars, each of said bars having a lateral flexibility between said base end and said distal end thereof;
• and
• said output member connected to a central area of said leaf spring.

A vibratory conveying apparatus, comprising:

• a base member;
• a trough elongated longitudinally;
• at least one elongated flexure member having a base end and a distal end;
• and
• at least one leaf spring having a first end and a second end, and extending at an angle to said elongated flexure member and connected at said first end thereof to said distal end of said elongated flexure member, said flexure member and said leaf spring connected in series between said base member and said trough at said base end and said second end.
