Abstract: A golf tee provides a preset elevation of the ball above the playing surface. The tee body is mounted at the end of a horizontal arm. The horizontal arm is fixed to a vertical arm with a barbed end. When the tee body is struck, it will pivot about the vertical arm and bend forward, but resist pulling out of the ground. The tee body may also be pivotably mounted on the horizontal arm, so that it also pivots about the horizontal arm to further dissipate forces. The tee body may be adapted to be replacable on the horizontal arm for replacement with a tee body having a different elevation.

Abstract: A tool especially designed for a workman in a particular industry has an elongate handle with a retractable sliding knife blade at a first end. At a second end a pair of rotatable wheels are mounted. When constructed for screen installation, one of the wheels has a convex edge for forming the screen in the groove of the screen frame and the other wheel has a concave edge for firmly holding a locking spline and forcing it into the groove to lock the screen in place. Where constructed for the paperboard box fabricator, one of the wheels has piercing points for laying out a pattern (a pounce wheel) and the other wheel has a convex edge for pressing a folding groove into the paperboard. The tool makes it possible for the worker to perform three different tasks normally performed in sequence with a single, hand-held tool to speed up his work, the knife being for trimming off screen or paperboard as required.
