US Patent:

49763784, Dec 11, 1990

Filed:

Mar 19, 1990

Appl. No.:

7/497733

Inventors:

Jerome J. Bush - Holland MI

Assignee:

Hamilton Distributing Company - Hamilton MI

International Classification:

B67D 508

US Classification:

222 55

Abstract:

A metering device for measuring bulk particulate material, such as feed, includes a hollow casing having a paddle gate positioned therein. Rotation of the paddle gate dispenses a predetermined weight of particulate material into the outlet port of the device. A monitoring mechanism monitors the back up of dispensed material in the outlet port stopping the flow of material into the metering device should the backed up material reach a predetermined level, thus avoiding jamming of the paddle gate.

Abstract:

A parted annular piston ring having an outer periphery for engaging a cylinder wall of an internal combustion engine. A band of hard, wear-resistant material is secured in a groove which extends circumferentially completely around the outer periphery. The band is disposed axially between upper and lower narrow lands. An overlapping joint construction is provided at the parted ends of the ring and comprises mutually circumferentially overlappable surfaces inclined at an acute angle relative to the plane of the ring and terminating in the outer periphery of the ring along edges disposed in the upper land. The upper land is wider than the lower land, and the mutually overlappable joint surfaces terminate at their radially inward edges in the bottom side wall of the ring. The band has axial extending end edges exposed at the split, and the outer periphery of the ring has a barrel face contour such that the maximum outside diameter of the ring falls within the outer wear surface of the band.
