  • Patent number: 9140363
    Abstract: A brush seal cover assembly that includes a brush cover having a shroud that substantially encloses a brush mounted in a holder without removing the holder from the equipment to which it is mounted. The assembly includes a pair of brush cover halves integrally formed to provide an outer bristle guard capable of supporting the weight of a person and a pair of brush shields on opposite sides of the brush that prevent direct impingement of pressurized gas or liquid enabling maintenance and cleaning of the equipment to be performed while leaving the brush mounted in place without damaging the brush. The cover includes a pair of mounting plates configured for mounting of the cover by clamping or by compression between fasteners without having to remove the brush holder from the equipment or the brush from the holder.

  • Patent number: 9068655
    Abstract: A quick change brush holder of a brush seal having a plurality of spaced apart deflectable brush retaining arrangements that include a tab that is bent into a brush receiving channel toward a brush engaging or retaining position to releasably retain a brush in the channel and that is bent away from the brush engaging or retaining position when it is desired to remove the brush or install a brush in the holder. Each tab has a brush abutment edge that abuts or stops a shoulder of a tape or spine of a brush in the channel preventing removal from the holder when disposed in a brush engaging or retaining position. The brush abutting edge extends generally parallel to the channel enabling a brush to be inserted transversely relative to a lengthwise extent of the holder tape or spine first into the holder.
