Description: |
| This invention relates more particularly to the making of what are known or termed "dovetails," blind, and other tenons and mortises in the ends of boards or strips of wood. The objects of the invention are to employ dies so arranged and operated as to form the tenons and mortises without removing the section of the wood occupying the place of the mortise; to furnish an upper and lower die, the upper one of which is given a powerful or forcible stroke by which the section of wood for the mortise is driven bodily into the fiber of the main wood below the base of the tenon and mortise; to construct an upper die and a lower die with the upper die movable and the lower die fixed and receiving between the dies a piece or strip of wood, with the dies so operated as to crush the section of wood for the mortise bodily into the fiber of the wood at the base-line of the tenon and mortise; to furnish a backing-plate and guide with an upper and lower stripper co-acting with a movable upper die and a fixed lower die- for receiving and supporting between the strippers and dies the piece or strip of wood to be acted upon; to furnish a backing plate and a jaw or guard cooperating with a movable upper die and a lower fixed die for forcibly driving the section for the mortise bodily into the fiber of the. wood below the base-line of the tenon and mortise and preventing the in-driven section of wood from out-bulging, so as to destroy the continuity of the face of the piece or strip of wood; to form a tenon and mortise by bodily driving the mortise-section of the wood into the fiber of the main portion of the wood below the baseline of the tenon and mortise; to form a dovetail, blind, or other tenon having the. mortise-section bodily driven into the fibers of the wood below the base-line of the tenon and mortise; to form a tenon having the mortise produced with straight side walls and a straight uninterrupted base-wall be forcibly driving the section of the mortise into the fiber of the wood below the base-line of the tenon and mortise, and to improve generally the construction and operation of the dies and the formation of the tenon and mortise as a whole. |
