Abstract
The driving mechanism has a drive shaft which rotates a driving block. A cam is mounted for rotation to the driving block and is received in a slot of a follower. As the cam rotates, it rolls backwards and forwards in the slot and causes the follower to rotate. A connecting rod is affixed to the follower and is rotated by it. The connecting rod rotates about an axis parallel to, but offset from, the axis about which the drive shaft rotates. The rate of rotation of the drive shaft is unvarying whereas the connecting rod rotates at a varying rate. A crank is affixed to the connecting rod and imparts reciprocating motion to the tray. A link can be substituted for the cam.
Claims14
Apparatus for causing particulate material to advance including:
- an oscillating bar and a rotating bar, said rotating bar being mounted in bearings and adapted to rotate therein;
- at least one spacer which interconnects said bars and maintains said bars in a spaced relationship;
- driving means operatively connected to said oscillating bar and imparting oscillating motion thereto;
- and a tray on which particulate material is adapted to advance, said tray being operatively connected to said oscillating bar and being caused to reciprocate thereby.
A driving apparatus for a shaking tray on which particulate material advances comprising:
- a drive shaft rotating about an axis;
- a link rotated by said drive shaft about an axis offset from the axis of rotation of said drive shaft;
- a follower connected to said link for rotation about an axis offset from the axis of rotation of said link;
- a connecting rod affixed to said follower and being rotated thereby;
- a crank rotated by said connecting rod and being adapted to be operatively connected to the shaking tray for imparting reciprocating motion to said tray.
