Abstract
A mortice and tenon joint of two structural members which avoids the protrusion of the tenon beyond the mortice. Across the tenon (11) of one member (10) there is cut a dovetail aperture or slot (12), and a movable tapering wedge (16) of similar dovetail cross-section is slidably housed within a tapering channel also of similar dovetail cross-section which crosses the mortice (14) of the other member (13) such that when the tenon (11) is inserted wholly into the mortice (14) the wedge (16) may be driven along the tapered channel to become firmly engaged within the dovetail aperture or slot (12) thus to lock the members (10, 13) together and prevent them from separating until the wedge (16) is withdrawn.

A mortice and tenon joint of two structural members, characterized in that across the tenon of one member there is cut a passage of tapered cross section, and in that a movable wedge having a similar tapered cross-section is slidably housed within a channel also of similar tapered cross-section which intersects the mortice of the other member, whereby when the tenon is inserted into the mortice, the wedge may be driven along the channel to become firmly engaged within said passage to prevent the members from separating until the wedge is withdrawn.
