Abstract: Selected lengths of a strip of material are cut either continuously in an automatic mode or each selected length is cut in a manual mode by manual activation of a switch. When the thickness of the strip of the material being cut exceeds a predetermined thickness or is less than a predetermined thickness, this difference is sensed so that this portion of the strip of the material is cut as soon as it ceases to exceed the predetermined thickness or be less than the predetermined thickness. In the automatic mode, automatic cutting may be stopped after this portion of different thickness has been cut either every time or every other time, and manual activation is required to start another automatic cutting.

Abstract: A stylus is mounted on a carriage which also supports a work plate adapted to be positioned beneath a punch.

Abstract: For band saw machines, a replaceable surface band wheel is disclosed wherein a helical groove is machined in the peripheral surface of a substantially conventional disk-shaped band wheel of the flanged type to extend from the rear face flange to the non-flanged front face of the band wheel. A wire is wound about the peripheral surface such that the wraps of wire lie in the helical groove and extend radially above the peripheral surface. The wire, so placed, forms an inexpensive replaceable cutting band contact surface. The depth and pitch of the helical groove and the wire size are selected to insure that the wire extends partially above the peripheral surface and to provide space between adjacent wraps of wire so that during cutting operations cutting chips and scale which might otherwise loosen the wire or cause abrasive wear to the band wheel peripheral surface are forced temporarily into the spaces between the wraps of wire.

Abstract: An improved flying saw of simplified and more economical construction is disclosed which operates smoothly with reduced vibration and which performs in an improved manner at higher operating speeds. The machine has a main crank arm with a rotary saw blade at one end and an adjustable counterweight at the opposite end, a stabilizing crank arm with a counterweight, and a connecting rod causing the arms to rotate in unison. Both arms telescope to permit simultaneous adjustments of arm radius while screw jacks adjust the height of the crank axis relative to the work. The work is supported on a wheel having a special sliding-block eccentric which moves the wheel in a vertical direction to deflect the work into the path of the rotary saw blade. A quickdrop support bracket permits lowering of the wheel and its eccentric away from the path of the work in an emergency situation so that flow from the mill need not be interrupted.

Abstract: The invention relates to a spiral saw blade wherein the teeth are divided into two or more groups with gaps or cut-outs between the groups of teeth, such gaps or cut-outs being void of teeth. The gaps or cut-outs are disposed diametrally opposite each other on the spiral saw blade, and, hence, on rotation the centrifugal forces go through the middle point of the saw blade and their maximum values are directed toward the groups of teeth respectively. Also, the invention provides teeth of varying heights with the first tooth of each group of least height and each succeeding tooth of progressively higher height, with a magnitude of height of the lowest compared to the highest no more than 2% of the diameter of the saw blade. The invention also provides a reinforcing salient in front of the first tooth of each tooth group which protects the first tooth from excessive stresses.

Abstract: The power stroke of the within punch press results from the electrical interaction of an armature, attached in depending relation from a superposed positioned die set, and a solenoid coil located in the supporting base of the press. In assembling each component of the sub-assemblies consisting of the supported die set and of the supporting base, a positional relation is achieved for each component which in the assembly of the die set onto the base contributes to a proper projected positioning of the armature within the encircling solenoid coil, to thereby achieve the required electrical reaction therebetween without losses or other inefficiencies.
