Manufactured by R. R. R. Co. - Marietta, Washington County OH

Abstract: This invention relates to new and useful improvements in roof-framing tools; and its io primary object is to provide a device of simple construction whereby the rafters which compose the frame of a roof may be marked upon their faces and edges, so as to secure the proper bevels for the different styles of rafters employed. Another object is to so construct the tool that the same may be set after having been adjusted to the proper angles. With these and other objects in view the invention consists in providing two arms, which are hinged together at their adjacent ends and the opposite ends of which are connected by means of an adjustable rod provided with suitable graduations whereby the angle at which the arms are placed to each other is readily indicated. The invention also consists in providing extensions which are hinged to the free ends of the arms at right angles thereto and which are adapted to overlap the edges of the rafters, upon which are placed the arms above referred to. These extensions are also connected by an adjustable rod bearing suitable graduations and whereby the angle to be marked upon the edge of the rafter may be readily determined. Claim: The combination of arms having right-angle extensions and hinged at their adjacent 0 ends, a tube pivoted at one end directly to one arm and having its other end extending toward the other arm, a rod having graduations and pivoted at one end directly to the last-named arm and having its other end extending toward the first-named arm and fitted to the tube, means located on the tube for binding the tube and rod to their adjustment.
