Patent ID: 8052182

Claim:
Apparatus comprising an assembly of a housing and a handle, the housing having a wall through which an opening provides a passage that connects a forwardly facing surface and a rearwardly facing surface of the wall, the handle being graspable, being located forwardly of the wall and the opening, and having a shaft connected thereto that extends rearwardly from the handle through the opening along a principal axis about which the handle can be turned relative to the housing when grasped, the assembly further including a spacer drivingly connected to the handle to turn therewith about the principal axis, the spacer having one generally cylindrical portion extending along the principal axis from the handle to the forwardly facing surface of the wall, and having another portion extending through the opening of the wall, and the assembly further having a single piece, integrally formed, three part seal having a first part that defines a substantially cylindrical formation of the seal that extends closely about and frictionally grips the generally cylindrical portion of the spacer to drivingly connect the seal to the spacer to turn therewith about the principal axis, the seal having a second part that defines a thin annular skirt formation of resilient material that extends continuously and without interruption from the generally cylindrical portion of the spacer where a third part of the seal formed by only a thin ring of material located adjacent the cylindrical portion of the spacer integrally connects the first part of the seal to the second part of the seal, with the thin annular skirt formation of resilient material fully underlying the cylindrical formation of the seal and being pressed flatly into engagement with only an annular surface portion of the forwardly facing surface of the housing wall that concentrically encircles the opening at a location on the forwardly facing surface spaced radially outwardly away from the opening, with the thin, flattened, annular skirt formation that forms the third part of the seal being the only portion of the seal that engages the housing wall and wipes along the annular surface portion of the forwardly facing surface of the housing wall when the handle is grasped and turned to cause the seal, the spacer and the handle to turn in unison with the shaft about the principal axis.
