  • Patent number: 7010860
    Abstract: A cutting device is operable with one hand for cutting a circle or an elliptical shape in a sheet of material. In a first embodiment for cutting elliptical shapes, the cutting device includes a first member for placement on the sheet material and a second member for simultaneous pivotal and translatable movement with respect to the base plate. The first member has a first pivot point that is movable along a first axis, while the second member has a second pivot point that is movable along a second axis substantially perpendicular to the first axis. The first and second members are operably connected to each other at the first and second pivot points. A knob is connected to one of the pivot points and is sized to be grasped by one hand and rotated. 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 base plate.

  • Patent number: 6052909
    Abstract: A cutting device is operable with one hand for cutting an elliptical shape in a sheet of material. The cutting device includes an elliptically-shaped base plate for placement on the sheet material and a cutting member for simultaneous pivotal and translatable movement with respect to the base plate. The base plate has a first pivot point that is movable along a first axis, while the cutting member has a second pivot point that is movable along a second axis substantially perpendicular to the first axis. The base plate and cutting member are operably connected to each other at the first and second pivot points. A knob is connected to one of pivot points and is sized to be grasped by one hand and rotated. Rotation of the knob about the one pivot point causes the cutting member to rotate and slide in an elliptical pattern with respect to the base plate to thereby cut an elliptical shape in the sheet of material.
