Molding affixed with wedged divider track

摘要

An elongated wedge shaped spline (1) can be used for joining work pieces in a dovetail joint. It can be used in joining a work piece, such as molding (5) in a dovetailed joint. An expansion track having a pair of spaced apart flanges (20) extending at a right angle from the front surface of the divider track (2) is first affixed to a surface. The wedge shaped spline (1) is positioned between and in abutment with the upper portion of the spaced apart flanges (20). A fan shaped mortise on the back surface of a work piece is positioned over the wedge shaped spline (1) between and abutting the upper portion of the spaced apart flanges (20). Pressure is applied on the front surface of the work piece for seating the work piece on the divider track (2), thereby forcing the wedge shaped spline (1) between the flanges (20) and spreading the flanges (20). The spread apart flanges (20) engage the side walls of the fan shaped mortise for joining the work piece in a dovetailed joint with the divider track (2).
