  • Patent number: 6425548
    Abstract: A core/hub assembly for a printing device that provides for easy alignment and insertion, and maintains a secure interface to prevent slippage of the core during printer operation, is disclosed. A hub includes keys mounted at a proximal end which serve to transmit torque when engaged with a core. The hub further includes splines configured to be received within a core and provide longitudinal support thereto. A core includes a plurality of longitudinally extending ribs that cooperate to form channels configured to receive the splines of the hub. A portion of the ribs include compliant radially oriented leaf springs which center the core on the hub and provide a physical fit of the core on the hub by engaging the keys at the proximal end of the core when properly inserted therein.
    Type: Grant

  • Patent number: 5755921
    Abstract: A press for transferring images from pictures or substrates to other objects, such as mugs or other cylindrical objects. The press comprises a flexible band or jacket type clamp lined with suitable compressible material and capable of being clamped tightly against a generally cylindrical outer surface of an object, with the image to be transferred against such outer surface. The image is urged into intimate contact with the outer cylindrical surface by the clamping pressure transferred through the compressible material. An adjustable clamp permits ease of placement of the band type press onto the object to which the image is to be transferred.
