Patent number: 8083051Abstract: A bulk materials pump feeder having a housing and a rotating drive rotor for transferring material from an inlet to an outlet of the housing. The drive rotor has a hub. Drive disks extend away from the hub toward a housing inner wall. Three structural features of the feeder reduce the tendency of material to jam between the drive rotor and the housing or other stationary parts. First, the distance between the circumferential edges of the drive disks and the housing inner wall increases from the inlet to the outlet in the direction of rotation of the drive rotor. Second, a low-friction brush seal disposed on the periphery of the drive disks seals the area between the periphery of the drive disks and the inner wall. Finally, a materials scraper having a flexible tip is mounted in the housing and extends into the drive rotor between the drive disks.Type: GrantFiled: November 29, 2007Date of Patent: December 27, 2011Assignee: K-Tron Technologies, Inc.Inventors: Timothy R. Baer, James T. Foley

Patent number: 7677864Abstract: A bulk materials pump feeder having a housing and a rotating drive rotor for transferring material from an inlet to an outlet of the housing. The drive rotor has a hub. Drive disks extend away from the hub toward a housing inner wall and have a compliant edge configured to deflect or compress when presented with pinched material rather than jamming.Type: GrantFiled: October 11, 2006Date of Patent: March 16, 2010Assignee: K-Tron Technologies, Inc.Inventors: Timothy R. Baer, James T. Foley, Glenn Meredith

Patent number: 6832887Abstract: A bulk materials pump feeder having a housing and a rotatable drive rotor mounted in the housing for transferring material introduced into the housing through an inlet to an outlet for discharge of the material from the housing. The drive rotor has a hub and a plurality of drive discs extending away from the hub toward an inner wall of the housing. To reduce the tendency of material passing through the housing to wedge between the inner wall of the housing and the circumferential edges of the drive discs, the distance between the circumferential edges of the drive discs and the inner wall of the housing increases from the inlet of the housing to the outlet of the housing in the direction of rotation of the drive rotor.Type: GrantFiled: April 9, 2002Date of Patent: December 21, 2004Assignee: K-Tron Technologies, Inc.Inventors: Timothy R.

Patent number: 5477792Abstract: A method of continuously applying an additive to soil with a soil treating apparatus as the soil treating apparatus is advanced in a travel direction along a planting path on soil being treated. The method includes the steps of resituating residue in the planting path in a lateral direction transverse to the travel direction away from the planting path, applying an additive to the soil, and moving soil laterally inwardly over the planting path after the additive is applied to the soil. An apparatus is provided for practicing the method.Type: GrantFiled: October 21, 1993Date of Patent: December 26, 1995Assignee: Dawn Equipment CompanyInventors: James H. Bassett, Timothy R. Baer
