  • Patent number: 4275506
    Abstract: A planar pattern making device that fits around a patterned object retaining an indication of the patterned object's surface within the plane of the pattern making device. A pair of opposed symmetric hinged arms are sized so that when closed around the object, they roughly fit the object to be patterned. A plurality of pins reciprocate inwardly from both arms to contact the surface of the object to be patterned. According to the method of the invention, the pattern making device is then latched and the pins are reciprocated to contact the surface of the object to be patterned in a predetermined plane. The arms are released, retaining the indication of the patterned object's contour through the pins.
