Description

FIG. 1 is a perspective view of the outer surface of an operator housing as oriented relative to a window sill and sash (not shown), with an operator handle such as would typically be used with the housing shown in phantom;

FIG. 2 is a top view of the outer surface of an operator housing;

FIG. 3 is a front view of the outer surface of an operator housing; and,

FIG. 4 is a left end view of the outer surface of an operator housing.

The housing is normally mounted along its near and bottom to a window sill and sash (not shown) and the rear and bottom are therefore not normally visible. Accordingly, the rear and bottom views of the outer surface of an operator housing are not shown herein as they are unclaimed subject matter. Further, the end of the raised portion over which the handle is normally secured as shown in FIG. 1 is also not normally visible. Therefore, that end portion delineated by the surrounding dashed line in FIGS. 2 and 3 is also not a portion of the claimed subject matter.
