Abstract: The manufacture of bent knives for wood cutting machines is simplified and made less expensive by designing the knife so that the finish grinding operation on its opposite faces may be performed before, instead of after, the bending operation on a flat plate. This is made possible by reducing the plate thickness to 1/4 inch or less which permits a ratio of radius of bend to plate thickness of at least 2.25. This ratio virtually eliminates breakage of the knives because of abusive processing.

Abstract: A router guide assembly adapted to be releasably or semipermanently attached to the work face of a router. The router guide assembly includes a circular base plate having a central aperture through which the cutting bit of the router extends. A pair of guide posts may be adjustably mounted to the base plate on each side of the cutting bit perpendicularly to the base plate and are laterally adjustable relative to the cutting bit. The guide posts may also be removed from the base plate so that the base plate can serve as the work face of the router.

Abstract: The present invention provides an improved method of forming a metal article having a plurality of airfoils which extend outwardly from a hub. The metal airfoils are formed separately from the hub. In forming a mold to cast the article, blade portions of the metal airfoils are coated with wax. The metal airfoils are then placed in a circular array and are covered with a coating of liquid ceramic mold material. This wet coating of ceramic mold material is dried to form an annular mold wall section having a plurality of recesses in which the blades of the metal airfoils are disposed. The wax coating over the metal airfoil blades is subsequently removed from the recesses to provide space between the blades and the side walls of the recesses. The annular mold wall section in which the blade containing recesses are formed is then connected with top and bottom mold sections to further define a mold cavity having a configuration corresponding to the hub portion of the article.

Abstract: An automatic machine for forming bee box components from wooden stock members by grouping the members in a single row and indexing them past several work stations at which the members are formed into the box components. The row of engaged members pass by the first cutting station where end grooves are cut in opposite ends of the individual members as they pass by. Guide bars then are received within the grooves and support the members as they are moved along to a second cutting station. At this station, angularly oriented milling heads form grooves along the longitudinal side edges of the stock members. The row is moved along in increments by an indexing mechanism that receives successive individual stock members from a feed mechanism. The indexing mechanism also includes a drilling assembly that functions to form longitudinally spaced holes through the members as they are received and indexed forwardly.
