Abstract: A window is secured within a window opening in a log wall for vertical movement within the opening and relative to the wall to compensate for wall settlement. Connecting members are at least partially disposed within the opening and between the jamb members which comprise the window frame and the logs which define vertically disposed sides of the opening. The connecting members are secured in fixed position to the window frame and have vertical slots which receive fasteners which secure the connecting members to the logs which define the sides of the opening to facilitate vertical movement of the window within the opening and relative to the wall. Another embodiment is disclosed wherein connecting members secured in fixed position to the window frame are received within vertical slots formed within the logs which define the sides of the window opening.

Abstract: A prefabricated log building has walls formed by horizontally extending, vertically stacked log courses joined by tongue and groove joints. The walls are joined at corners by mortise and tenon joints. Each tenon is partially defined by a portion of a tongue on an associated log and extends into a mortise partially defined by a portion of another tongue on another log. The tongue and groove joints cooperate with the mortise and tenon joints to form weathertight barriers which extend through the building corners. Joists supported by the upper log course of an associated wall extend in cantilever position beyond the wall and support rafters. Filler logs connected in tongue and groove relation to the upper log course extend between the joists. A soffit carried by the joists may cooperate with a tongue on the upper log course or with tongues on the filler logs to form a weathertight eave structure.
