Abstract: A cutting blade for cutting a wire has a blade body with a cutting face extending from a cutting edge. The body has a slidable surface for engagement with an opposing surface that allows relative movement between the blade body and the opposing surface to permit the cutting edge to cut the wire.

Abstract: A punching and stamping machine has a movably guided die plate frame, in which an eccentric shaft for the drive of the die is simultaneously disposed. The die plate frame is moved by means of a plate cam which is directly coupled with the eccentric shaft As a result, a forcibly guided movement is achieved between the die and the die plate which, with respect to the workpiece to be machined, is superimposed such that the die carries out only minimal movements with respect to the workpiece and therefore, particularly in the case of a hollow-cylindrical workpiece, permits the machining from the interior side to the exterior. As a result of this forced guidance, very high operating speeds can advantageously be achieved with a high precision.

Abstract: Glass gob shearing apparatus having opposed shear blades that reciprocate along generally parallel, opposed horizontal paths to periodically bring the shearing ends of the shear blades into partly overlapping contact with one another, to thereby shear a gob of molten glass from a stream of molten glass flowing downwardly between the shear blades. Contact loads between the shear blades are reduced by placing a shim between one of the shear blades, namely the shear blade that is the lower of the shear blades when they are in contact with each other, to thereby impart a slight downward inclination to such shear blade with respect to the other shear blade. Contact loads between the shear blades are further reduced by resiliently mounting the other shear blade to the blade holder to which it is attached, and this is done by positioning curved spring washers between the other shear blade and the blade holder to which it is attached.

Abstract: The tool holder of a machine for cutting a supply of insulated electrical conductor into discrete lengths employs a standard cutting blade. The standard blade serves as the outer boundary of the tool holder and of the remainder of the machine, thereby assuring that the cut lengths can pass to the next processing station without striking any component and thereby become disoriented. Use of the standard cutting blades is accomplished by employing conventional fasteners to retain the blade on the tool holder. The cutting blade is located in the tool holder by a slotted member and blade shank end locator.

Abstract: An override for a positive drive mechanism which includes a first bearing block which is fixedly secured to tie rods and a second bearing block which is secured to the tie rods through release and relatch means. The blocks are designed to couple to either a positive drive unit or a unit to be driven by the drive unit. When the driven unit encounters a solid obstruction, release and relatch means associated with the second bearing block will permit the tie rods to slide within the second bearing block, thereby allowing the driven unit to stop. The override mechanism is advantageous in that within a relatively small physical size when a high maximum preselected load in the mechanism is attained, the mechanism will release and apply no further load to the drive. Very long override strokes can be accommodated after which the device will reset at the end of each stroke.
