  • Patent number: 4466675
    Abstract: A knock-down drawer assembly is provided with a front panel, a pair of side panels, a rear panel, and a bottom panel. The front, rear, and side panels are provided with channels for receiving the bottom panel.

The opposing sides of each mortise taper inwardly at a constant angle along the vertical length of the mortise. Each of the side panels has a dovetail tenon on one end of the panel. The sides of each tenon taper inwardly along the vertical length of the tenon and each tenon is adapted to be received in a mortise of the front panel. A shoulder is provided on the rear end of each side panel for locating the rear panel along the length of the side panel relative to the front panel. Fastening means are provided for securing the side panels to the rear panel.

  • Patent number: 4463644
    Abstract: Two rails, each having a straight edge, two ends and a cross section defining a channel, are placed in an end-to-end butting relationship to form a continuous straight edge. A joiner plate has an arcuate cross section and has lateral margins for being received in the rail channels. The plate is placed in the rail channels and is fastened to the rails so as to deflect the plate downwardly and force the lateral margins of the plate tight against the rails to align the rails and hold the rails together.
