Abstract: A slitting assembly for producing a plurality of "interrupted cut" slits in a large sheet of sport card photos includes a horizontal support track carrying a plurality of individual upper slitting assemblies each including a freely rotatable upper hub, an upper blade concentrically attached to the upper hub, a resilient band circumferentially disposed on the upper hub to frictionally engage the top surface of the sheet being slit, and an upper blade biasing element to resiliently urge an edge of the upper blade against an edge of the corresponding lower blade. The upper blades are precisely parallel to the lower blades to avoid interference with notches provided in the lower blades to interrupt the slits being made. The locations of the notches are selected to compensate for slippage resulting from the frictional engagement.

Abstract: A hand machine tool operated with two hands has a machine housing composed of insulating synthetic plastic shells, a fixed, web-shaped main handle formed as a part of the machine housing, an auxiliary handle, a drive including a motor and a transmission, at least one inner housing accommodating the motor and the transmission and surrounded by the synthetic plastic shells, and a tool driven by the drive. The handles, the machine housing, the inner housing and the tool are arranged so that forces applied to at least one of the handles are withdrawn from the machine housing by transferring the forces by the main handle directly to the inner housing without deforming the machine housing and then transferring the forces from the inner housing to the tool.

Abstract: An apparatus for loading individual connectors into a wire-harness making machine includes a feed track which feeds a supply of connectors which have been separated from a connector supply chain. The lead connector is advanced into a feed channel whereupon a severing knife is advanced into the feed channel to separate the lead connector from an adjacent connector. The severing knife remains in place momentarily as a shuttle mechanism is actuated to move the severed lead connector along the feed channel, the severing knife blade forming a portion of the feed channel during the shuttling of the severed connector. Optical sensors may be mounted in proximity to the severing knife in order to verify the presence or absence of a connector prior to severing.

Abstract: A punch press ram drive is described in which a reversible electrical servo motor is coupled to a crankshaft having an eccentric journal driving a pitman arm connected to the ram. The electrical servo motor is operated by program controls so as to either cause rotation or oscillation of the crankshaft to drive the ram through various programmed stroking modes, in which punch position, velocity, acceleration, varying over the course of a stroke may be programmed.

Abstract: An emergency safety-belt cutter is provided with frame having an opening. A slide is disposed within the frame opening for receiving and closely supporting the safety-belt. The slide constrains the safety-belt to keep the safety-belt from wrinkling during the cutting movement of said blade. A cutting blade having a cutting edge is attached to the frame and protrudes into the opening. The blade engages and cuts the safety-belt supported in the slide upon movement of said frame transversely over said safety-belt. Furthermore, a guard means is detachably secured to the frame to prevent cutting the safety-belt during inadvertent pulling of the frame. The guard means includes a sheath positioned in front of the cutting blade cutting edge to protectively sheath the blade. The guard means is detachable from the frame to unsheathe the cutting edge to permit cutting of the safety belt.

Abstract: A puzzle cookie cutter includes a cutting die holder and at least one cutting die removably securable in the holder. The die or dies provide for the cutting of cookie dough, batter, or the like into several separate, irregularly shaped and sized interfitting pieces, which pieces may be reassembled as a puzzle after baking to provide entertainment for the consumer of the cookie. The dies may be provided in virtually any regular or irregular geometric shape, animal or other caricature or representation, and/or any alphanumeric character, as desired. The die or dies may also provide for the spaced apart separation of the cut dough or batter, to allow for expansion or flow of the batter or dough during the baking process, in order that the baked pieces will have a close fit with one another without interference.

Abstract: A method of making a pair of rotary die cylinders with lands having coacting cutting edges which cut blanks from a web of material passing through the nip of the rotating dies. In cross section each land has an outer face and a pair of spaced apart side faces which are parallel to each other and perpendicular to the chord of the outer face to provide a clean cut and facilitate release of the cut blank from the cutting blades as it emerges from the nip of the dies. The die cylinders are journalled for rotation by recesses with frusto conical locating surfaces in their opposed ends. Each die cylinder is made by machining the recesses in the opposed ends of a generally cylindrical workpiece of tool steel and then utilizing the recesses to locate and orient the workpiece relative to a cutting tool to produce a cylindrical surface on the workpiece concentric with the axis of the recesses and then to machine away portions of the periphery of the cylindrical surface to form the cutting blade lands thereon.
