Appl. No.:

5/830881

Inventors:

Charles L. Watkins - Chicago IL

Assignee:

Goodman Equipment Corporation - Chicago IL

International Classification:

B65G 2700

US Classification:

198761

Abstract:

A drive mechanism for use with a shaker conveyor to effect longitudinal reciprocating movement of a conveyor trough is disclosed, the drive mechanism including a flywheel mounted for driving rotation about its center axis and connected to a slide block longitudinally movable along a lever arm mounted for pivotal movement in a plane perpendicular to the axis of rotation of the flywheel. The slide block is connected to the flywheel eccentric to its axis of rotation and the lever arm is connected to the conveyor trough so that constant speed rotation of the flywheel effects reciprocating movement of the conveyor trough in a manner to advance particulate material along the trough.

Appl. No.:

5/918965

Inventors:

Charles L. Watkins - Chicago IL

Assignee:

Goodman Equipment Corporation - Chicago IL

International Classification:

B65G 2706

US Classification:

198758

Abstract:

A shaker conveyor is disclosed which includes a conveyor trough supported for reciprocating movement and having drive means including a pull rod adapted to effect reciprocating movement of the conveyor in a manner to advance discrete particles therealong. The conveyor trough has a resiliently mounted discharge end adapted to withstand forces which might otherwise tend to damage the trough and pull rod, and the pull rod is adapted to undergo axial foreshortening when subjected to predetermined axial loading so as to prevent damage thereto.
