  • Seal with Spiral Grooves and Mid-Lip Band
    Publication number: 20110204579
    Abstract: A dynamic seal advantageously utilizes a plurality of grooves on the active side or surface of the seal to capture a leaked lubricant and hydrodynamically pump the lubricant back into the lubricated side of the seal. The grooves are interrupted at an intermediate location by a continuous circumferential band that aids in preventing leakage past the band when the shaft is not rotating and the grooves on both sides of the band pump contaminants away from the sealing lip.

  • Cleaning implement
    Patent number: 7984528
    Abstract: A cleaning implement that includes a connector for connecting a handle to a base block. The connector prevents the handle from rotating relative to the base block and, thus, the connector prevents the handle from unscrewing or otherwise loosening or disconnecting from the base block. The base block can include a headpiece supported between oppositely arranged shoulders, a generally cylindrical flange projecting from the headpiece, and a generally cylindrical opening extending through the cylindrical flange. A slot may be formed in an inner surface of the cylindrical flange. A ferrule that can have a generally dovetail-shaped projection provided on its outer surface can be secured to an end of the handle. The projection and the slot can form a joint when the handle is connected to the base block. This joint substantially prevents the handle from rotating relative to the base block.

  • Shaft Seal with Lubrication Device
    Publication number: 20110163507
    Abstract: A shaft seal assembly for use with a reciprocating or rotating shaft includes a shaft seal, a lubricant-storing ring, and a retainer. The retainer and ring can be formed as a subassembly and then combined with a shaft seal. The seal includes an annular body portion, a first sealing lip portion, and a first pocket portion. The first sealing lip portion has a substantially uniform axial dimension and is adapted to sealingly engage a shaft. The first pocket portion includes a plurality of pockets, each having an opening toward the first sealing lip portion. The plurality of pockets are each adapted to collect a working fluid when the shaft axially displaces in a first direction and to dispense the working fluid when the shaft axially displaces in a second direction.
