Abstract: For use with any type of saw and base such as a miter saw which can be set as to angle, the present apparatus comprises a pair of profile members corresponding to different sizes and shapes of conventional mold and such profile members may be supported at a proper angle on the flat bed of a table, such as a miter saw table, so that the piece of mold being cut is placed in a proper face-to-face profile engagement position with the profile member and thereby held in the proper angle and the proper position to be cut exactly in the manner as the mold will occupy when installed on a ceiling or other place. The method is the procedure for positioning the profile member in place, holding same in position, placing the mold to be cut in face-to-face relationship coextensively against the profile member, and cutting same. According to this, two pieces of mold will be cut on each end of each piece so that the matching cuts will fit exactly when installed in place.

Abstract: The present machine, sometimes known as a beader or drum beader, receives a steel drum in a horizontal position and expands circumferential beads into the body to provide structural strength. A pair of opposed heads which reciprocate in and out of the drum body are driven respectively by means of a crank arrangement comprising a connecting rod which is fixed with a pivoting joint on the back of the head. The other end of the connecting rod is attached to gear by a pin which is offset from its center axis. Each head travels horizontally on a frame of the machine into and out of a drum which is placed thereon. A hydraulic cylinder provides the expansion of the dies on the head which are used to engage the drum and form the beads. Thus, the operation of the connecting rod is mechanical but the dies are operated by hydraulic cylinder in the head and when the proper stroke is reached that corresponds to the correct height of the bead the cylinder retracts the bead dies.
