Clamp nail driving tool

In a tool for driving clamp nails into work pieces having a driver element and means to cause said driver element to execute a driving and return stroke, a guide body through which said driver element moves in its stroke, a magazine for holding a stick of clamp nails, said magazine communicating with said guide body, said guide body having an aperture through which clamp nails are fed successively into position to be driven by said driver element;

• and aperture being configured with a relatively narrower upper portion and a relatively wider lower portion to assure that clamp nails cannot be fed through said aperture upside down, an adjustable rail in said magazine, whereby said magazine may accept several sizes of clamp nails, said guide body having a nose portion of W shape, the outer surfaces of said W being respectively at an acute angle with respect to the centerline of the tool, so as to fit into an inside corner of a mitered joint to be clamp nailed, the central inner surfaces of said W being respectively at an acute angle with respect to the centerline of the tool but inverted with respect to the outer surfaces of said W so as to fit over an outside corner of a mitered joint to be clamp nailed, narrow surfaces connecting the respective outer surfaces and central inner surfaces, said narrow surfaces being normal to the centerline of the tool for use in clamp nailing flat abutting surfaces, and a plate adjustably secured to said guide body and extending laterally therebeyond, and adjustable between a position in which it assists in positioning the tool at a 45.degree. angle for properly clamp nailing an inside mitered joint, and a position in which it assists in positioning the tool at a 30.degree. angle for properly clamp nailing an inside right angled butt joint.
