Abstract
In a power driven, portable surface treating machine, a mechanism is provided for clamping a surface treating material to the back plate of the surface treating machine. The clamping mechanism comprises a back plate having a clamp seat at one end thereof extending horizontally across substantially the entire length of said one end of said back plate, and a device for clamping one end of the surface treating material. The clamping device includes a manipulative over-center camming lever pivotably supported on the back plate, the lever having a power arm section which has a finger grip at its rear and a camming arm section offset laterally from the forward end of the power arm section. The clamping device also includes a reciprocably shiftable, resilient wire clamping member having a connecting section substantially perpendicular to and pivotably mounted on the camming arm section of the lever and a clamping section fixedly secured to the connecting section and extending substantially parallel to the clamp seat in the back plate, whereby when the camming lever is moved to its over-center position the clamping section of the resilient wire clamping member aligns itself within the clamp seat to thereby clamp the end of the surface treating material.
