Abstract: An operation device includes a connecting member mounted on and moved with a working device of a tenoner. A positioning mechanism is mounted on and moved with the connecting member and includes a tube mounted on the connecting member and adapted to be fixed at various positions, an elastic member and a shaft retained in a hollow of the tube. The shaft includes an end extended outside of the tube and a roller mounted on the end and engaged with a guiding member. The elastic member is disposed between the tube and the shaft and selectively depressed such that the elastic member enables the shaft to movably engage with an undulated edge of the guiding member in a quick and accurate manner.

Abstract: Apparatus for making tenons and forming shoulders on wood ends with a stand having two opposing sides and a attachable stand top, a two piece router bracket that accepts different diameter router motors, a threaded rod bracket with at least 3 apertures for receiving a threaded rod, a threaded rod with a square tapered end, a tube connector that receives and secures smaller round diameter tubing and bolts to the top of the router bracket, a round steel slide pole, a wooden work piece holder with a round tube with a square tube attached at a 90 degree angle a a square tube with a fixed stud at one end. A preferred embodiment includes the curved thread engaging clip moves slidably on a steel rod. A preferred embodiment includes locking collars used as adjustable stops positioning the curved engaging clip in a engaging and disengaging location on the threaded rod.

Abstract: Floor panels are shown, which are provided with a mechanical locking system including tongue and grooves provided with protrusions and cavities which are displaceable in relation to each other and configured such that the protrusions can obtain a vertically unlocked position where they match the cavities and a vertically locked position where the protrusions overlap each other.

Abstract: A mortise/tenon machine has a base which includes two side plates, a guiding plate installed between the side plates transversely and horizontally, numbers of openings formed on a side of the guiding plate, and a rail member installed between the side plates and in the same horizontal position of the guiding plate. A workpiece is slideably disposed on the openings. A sliding base is slideably mounted on the rail member. A working platform includes a bit installed at a first end thereof, with the bit extending from a desired opening, and with another end of the working platform longitudinally disposed on the sliding base.

Abstract: A method of forming an assembly including a first workpiece having a surface provided with a mortise and a second workpiece provided with a tenon inserted into the mortise joining the workpieces together in which the second workpiece is disposed in a certain orientation relative to the first workpiece to provide a certain disposition of the workpieces when joined together, generally consisting of providing identifying marks on the surface of the first workpiece and the tenon of the second workpiece at locations assuming a certain disposition when the second workpiece is disposed in a certain orientation and the tenon is registered with the mortise; positioning the second workpiece relative to the first workpiece wherein the second workpiece is disposed in the certain orientation relative to the first workpiece, the tenon is registered with the mortise and the marks are disposed in the certain mark disposition; and displacing the second workpiece toward the first workpiece and inserting the tenon into the mort
