Abstract:
A hand-held device for forming an elliptical shape in a sheet of material, comprising:a first member adapted for placement on the sheet of material, the first member having a first pivot point that is movable along a first axis; a second member having a second pivot point that is movable along a second axis substantially perpendicular to the first axis; the first member and the second member being operably and slidably connected to each other at the first and second pivot points; and a knob connected to one of the first and second pivot points, the knob having a size and shape that allows grasping the knob by a thumb and all fingers on one human hand such that rotation of the knob about the one pivot point causes the second member to rotate and slide in an elliptical pattern with respect to the first member, wherein a slot is formed in one of the members and an opening is formed in the other of the members; and wherein the one pivot point comprises a fastener extending through the slot in the one member and through the opening in the other member, the knob being mounted to the fastener for holding the first and second members together, wherein rotation of the knob causes substantially linear movement of the fastener along the slot and rotational movement of the other member about the fastener.
