1. A laser beam deflector for protecting underlying portions of an item during laser cutting of overlaying stock, comprising:
- a deflecting surface "ds" of an arcuate cross-sectional configuration, said deflector being defined by first and second portions each having first and second end portions and an arcuate length "l" of about 180 degrees, said first end portions being pivotally connected to one another, said deflector being positionable between said overlaying stock and underlying portions desired to be protected, and said deflecting surface "ds" being immediately adjacent said overlaying stock.

Abstract
A laser beam deflector is useable for protecting underlying portions of an item during laser cutting of overlaying stock. The deflector has a base surface width greater than the overlying stock to be cut and a smooth deflecting surface of an arcuate cross-sectional configuration. The deflector is positionable between the overlaying stock and the underlying portions desired to be protected with the deflecting surface immediately adjacent the overlaying stock.

2. A laser beam deflector for protecting underlying gear teeth of a gear during laser cutting of notches in overlaying stock, comprising said overlaying stock having an outer surface and being separated from the gear teeth by a circumferentially extending groove having a groove depth "GD", as measured from a bottom of the groove to the overlying stock outer surface, a groove radius "GR" and a groove width "GW", said notches having a depth "D";
said deflector having a deflecting surface "ds" a base surface "bs" a base surface width "bsw" a thickness "t", a radius "r", and an arcuate length "l";
said deflector having dimensions relative to the gear wherein, said base service width "bsw" is greater than the groove depth "GD" said deflector radius "r" is substantially equal to the groove radius "GR", said thickness "t" of the deflector is less than the groove width "GW", said deflector arcuate length "l" extends at least 120 degrees, and said deflecting surface "ds" is of arcuate cross-sectional configuration.- View Dependent Claims (3, 4, 5, 6)
