Rotating Key Patents (Class 192/29)
  • Patent number: 6247197
    Abstract: A brush assembly includes a distributor having a slot matrix formed in an outer surface of the distributor, the slot matrix including a plurality of longitudinal slots intersecting a plurality of annular slots. The brush assembly further includes a housing having an inner surface abutting the outer surface of the distributor, a brush mounted on the housing and a shaft. During use, the flow of liquid from the shaft to the housing flows through the longitudinal slots and annular slots of the distributor. By appropriately selecting the dimensions and numbers of these slots, the flow of liquid from the shaft to the housing is readily redistributed. For example, the flow of liquid is redistributed to provide a greater amount of liquid to the ends of the brush than to the center of the brush.

  • Patent number: 5865286
    Abstract: Clutch mechanism for use in an automatic feed system includes a lockout device that prevents re-engagement of a disengaged clutch mechanism until such time as reset of the clutch is accomplished. When the clutch is first disengaged a mechanical flag cooperates with a specially configured shaft to prevent shaft rotation until such time when the flag has been urged out of blocking contact with the shaft.

  • Patent number: 4154406
    Abstract: A forage wagon or the like having components driven by a power take-off shaft and including apparatus for selectively disengaging the power take-off shaft and the driven parts. The disengaging apparatus includes a safety clutch having a circular drive clutch plate supported on a drive shaft of a power take-off shaft for rotation with the drive shaft and a driven circular clutch plate freely rotatably supported on the drive shaft. The driven clutch plate functions to drive the various driven parts of the forage wagon. In the normal operating condition, a drive pin, aligned parallel to the axis of the drive shaft, is received through bores in both the drive plate and the driven plate such that the driven plate rotates with the drive plate.
