  • Patent number: 4535648
    Abstract: A handle extension provides a means by which a control on a power-operated device, such as a snow thrower, can be manipulated from a more convenient and safer location. A rod-like control extension handle is coupled to an existing control handle or lever by a unique connecting bracket which is so configured that when the present invention is installed by an unskilled person, the said connecting bracket in combination with the said rod-like control extension handle prevents binding of the present invention with the existing control handle thereby permitting more precise control of the power-operated device.
