  • Patent number: 5797637
    Abstract: A hand operated leverage device is provided for contact with the outer surface of a roll of material, so that a relatively small amount of force applied to the device will result in a forward rotating movement of the roll of material a relatively short distance away from the user and away from the device. The support legs allow the device to be freestanding, with one of the support legs having the ability to accommodate a person's stepping force, while another support leg is pivotally connected to the body of the device and serves as a pivot point for the transmission of the force from the human operator to the roll of material. A curved, adjustable plate connected at the end of the leverage device enables it to actively engage the outer surface of the roll of material during the force-transmissive operation of the device.
