  • Patent number: 7497324
    Abstract: A right angle conveyor has a first trough and a second trough to move product by reciprocating motion with the second trough at an angle to the first trough. Rocker arms and corresponding reactor springs joined to a chassis form the first and second troughs. The first trough has a motor upon the chassis, eccentric cam, and a linkage to induce reciprocating motion into the conveyor. To induce reciprocation, the first trough has a first bracket connected to a yoke upon a trunnion joined to the chassis, a yoke connected to a slave drive spring bracket, a slave spring connected to the slave drive spring bracket and to a second bracket, the slave spring connected to a second bracket beneath the second trough. The yoke has three pinned connections to permit rotation.

  • Patent number: 6782995
    Abstract: A two-way vibratory conveyor includes at least one trough mounted on a base and a drive which reciprocally moves the trough(s). The conveyor, which in one embodiment has two interconnected troughs and in another embodiment has a single trough, includes a drive which uses a single motor. In the two-trough conveyor, the two troughs are driven in opposite directions. In the single-trough conveyor, the single motor is used to selectively drive the trough in one of two opposite directions. The troughs are mounted to a base using springs and stabilizer arms. The stabilizer arms, which are made of ductile iron, have been found to be withstand larger loads and have a longer useful life than currently available stabilizer arms.
