Joint-cutter
|
Bernard J. Spilker |
Cincinnati, OH |
"This invention relates to improvements in joint-cutters, which are machines for cutting the ends of frame-sections for picture frames, moldings, &c., in such a manner that said sections are ready to be joined together at the proper angle to form frames. This angle is usually a right angle, for which purpose the ends of the sections are cut off at an angle of forty-five degrees to form what is called a miter-joint. The material for the frames comes in long strips which are fed to the machine and but by it to the proper lengths, the lines of separation being so that the adjoining ends of each of the two separated pieces receive at the same time the proper angle for joining. The improvements on such machines and which form the subject of this invention relate to means to support the work in a manner that, when intricate moldings are cut which have rabbets or are under-cut and lack substance for support at such points, such weak parts are prevented from being broken down or splintered by the knives while they do the work..."
See also patent 212,409; although that earlier patent is not referenced in this patent's specification, the earlier patent (granted to John J. Spilker) is clearly a design ancestor. |
