Abstract: A cutting device for shingles that cuts shingles at angles. Several blades, each on pressure plates, are forced into engagement with shingles by rollers that engage one side of the plates.

Abstract: A card cutting apparatus for cutting business cards out of paper stock. The card cutting apparatus includes a housing. The housing comprises a base portion and an upper portion. The base portion has an upper side and a lower side. The upper portion is hingedly coupled to the base portion such that the upper portion may be selectively positioned between an abutted position and a removed position with respect to the base portion. The upper portion has a top surface, a bottom surface, a front surface, a back surface and a pair of side surfaces. The bottom surface has a cavity therein. A rod is rotatably mounted in the upper portion, and extends through the side surfaces and through the cavity such that the rod has a pair of ends each extending away from one of the side surfaces. The rod extends through and securely attached to a cam. A handle member is coupled to each of the ends of the rod.

Abstract: Manually and electrically powered die cutting machines for making paper cutouts with replaceable dies. A generally cubicle platen cutting head preferably mounted on a supporting cabinet comprises a rigid, supporting base with a pair of outwardly projecting, parallel side plates that surround a pair of spaced apart platens. A stationary platen is fixed between the sides. A movable platen is laterally suspended between the sides away from the fixed platen, defining a die-receptive compartment therebetween. A die selected to produce the desired shape, and the paper to be cut, are inserted within the die-receptive compartment in sandwiched relation before platen compression. The movable platen is suspended by pins projecting laterally away from its edges that engage suitable follower slots defined in the side plates. A crankshaft assembly pivots an elongated, roller-equipped crankshaft to displace the movable platen for cutting.

Abstract: An apparatus is disclosed for bringing a cutting die into engagement with a workpiece such as leather, the apparatus includes first and second plates secured to C-shaped frame members and a platen for supporting the workpiece that is movable relative to the second plate upon inflation of a bladder secured to the periphery of the second plate upon actuation of first and second valves connected between a source of pressurized air and the bladder.

Abstract: Automatic hollow punch search device and relevant control, for die-cutting machines, particularly for footwear production, in which a mobile head is associated to means to move it to and fro, both horizontally and vertically, above a fixed faceplate on which the material to be cut is placed, together with a hollow cutting punch. The movement means are automatically piloted by a drive circuit interlocked to manual starting means which provides means to carry out a complete head movement operating sequence from its positioning above the hollow punch to its lowering and return to the starting point after cutting.

Abstract: Apparatus is provided for controlling the movement of a member, such as a pressure head in a die press, the die press being of the type wherein the pressure head is horizontally movable relative to the material to be cut or otherwise impressed to locate the head in the desired position above the material. Once positioned, the head is vertically movable into engagement with a die which is pushed through the material to perform the cutting or impressing operation. The apparatus includes means for moving the member in first and second directions along a horizontal plane, preferably in the form of an electrically controlled motor. Means are also provided for moving the pressure member vertically, preferably in the form of an electrically operated hydraulic system. First and second switch means, in the form of triggers or push buttons, are operably connected to both the motor and the hydraulic system and when actuated individually energize the motor to move the pressure member horizontally.

Abstract: A die press for performing operations on material includes a planar support upon which material is placed and a pressure member movable toward and away from the support. Means for moving the pressure member are provided as well as means for controlling the pressure member moving means. A die carriage upon which a die is mounted is situated between the pressure member and the support and is movable relative to the support in first, second and third directions, one of which is the direction of movement of the pressure member. The linkage for mounting the die carriage maintains the die carriage in the plane of the support throughout the movement thereof. For safety purposes the control means is situated on the die carriage at a portion thereof remote from the path of movement of the pressure member. Preferably, the control means includes a pair of switches which require simultaneous activation in order to energize the pressure member moving means.
