A method of assembling furniture corner joints between framing members, such as rails or boards set at angles to each other. The corner joint is secured by connector plates, each of which has end portions set at right angles to each other corresponding with the angle of the framing members and having integral one-piece teeth struck from the body of the plate normal to the plane of the respective end portion. The teeth are of uniform length and are spaced apart in areas adjacent the end portions of the plate, leaving a smooth inner face on the connector plate in the area where the framing members would be brought together to form the joint. The method is in two steps, one of which causes the teeth on one end of the plate to penetrate the face of the framing members and thereafter the opposite angular portion of the plate is moved relatively toward the second framing member to cause the teeth thereof to enter the framing member. In each step the teeth, which are of uniform length, enter the adjacent face of the framing member in straight lines. These steps enable a plurality of corner joints of one article of furniture to be assembled and secured in one operation by successive steps.
A method of making a furniture corner joint between framing members in planes set at an angle to each other comprising placing over the corner a toothed connector plate having end portions disposed at an angle to each other corresponding with the framing members, each end portion having integral teeth struck out from the body of the plate over substantial areas thereof normal to the plane of the respective end portions and normal to the plane of the adjacent framing member, relatively moving one of the framing members with respect to the other framing member and the adjacent end portion of the connector plate toward each other penetrating the teeth thereof into said one framing member in a straight line, lengthwise of the teeth, and thereafter relatively moving the other framing member with respect to the one framing member and the adjacent end portion of the connector plate toward each other penetrating the teeth thereof into said other framing member in a straight line lengthwise of the teeth thereof.
A method of making a plurality of furniture corner joints between wooden framing medmbers in planes set at an angle to each other, comprising preparing toothed connector plates each having end portions disposed at an angle to each other corresponding with the angle of the framing members, each end portion having integral teeth struck out from the body of the plate normal to the plane of the respective end portions and normal to the faces of the adjacent framing members, assembling the plurality of connector plates at the ends of one framing member having one end portion of each connector plate extending parallel with said framing member, applying pressure simultaneously at opposite end portions of the framing member relatively forcing the teeth into said member, thereafter assembling additional framing members parallel with the other end portions of the connector plates, and simultaneously applying pressure in opposite directions to the last mentioned framing members and the adjacent portions of the connector plates in directions normal to the planes of the plates forcing the teeth into the framing member.
