Abstract
A milling machine for shaping blanks to create filter lenses for a clip-on accessory whose pair of filter lenses register with a pair of optical lenses in prescription eyeglasses when the accessory is hitched onto the frame of the eyeglasses. The frame of the eyeglasses is composed of two like half sections having a predetermined geometry, an optical lens being mounted in each half-section. The filter lenses in the accessory which are joined by a bridge piece have a geometry matching that of the half-sections of the frame whereby the appearance of the clip-on accessory is compatible with that of the eyeglasses.
Claims19
A machine for shaping blanks to create filter lenses to be included in a clip-on accessory having a pair of filter lenses which, when the accessory is hitched onto a pair of eyeglasses, having two half sections, then lie in registration with these half sections, said eyeglasses having a predetermined geometry that is matched by the geometry of the filter lenses, said machine comprising:
- A. A part of worktables each to support one of the blanks to be shaped, and each having a first motor for driving the worktable;
- B. A drill bit unit provided with a rotatable drill bit;
- C. An elevator supporting said drill bit unit and shiftable along a vertical axis to raise or lower the drill bit with respect to the blank on each worktable, and a second motor for driving the elevator;
- D. A carriage carrying said elevator and shiftable along a horizontal axis to move the drill bit back and forth with respect to said blank, said carriage being driven by a third motor;
- and
- E. A processor to coordinate the operation of the first, second and third motors to cause said drill bit to shape the blank to form a filter lens of the desired geometry.
A machine as set forth in 1, in which the drill bit drills holes in said blank to receive plugs of a clip for anchoring the clip on the filter lens so that the accessory can be hitched onto the eyeglasses.
A machine as set forth in 1, in which digitally stored in a database of the computer is digital data regarding the predetermined geometry of the frame, from which data the computer controls the motors to produce a filter lens having a matching geometry.
A machine for shaping blanks to create a pair of lenses to be attached onto the frame of a pair of eyeglasses, mounted in half sections of the frame, said frame having a predetermined geometry;
- said machine comprising:
- A. A pair of worktables each to support one of the blanks to be shaped, and each having a first motor for driving worktable;
- B. A drill bit unit provided with a rotating drill bit;
- C. An elevator supporting said drill bit unit and shiftable along a vertical axis to raise or lower the drill bit with respect to the blank on each worktable, and a second motor for driving the elevator;
- D. A carriage carrying said elevator and shiftable along a horizontal axis to move the drill bit back and forth with respect to said blank, said carriage being driven by a third motor;
- and
- E. A processor to coordinate the operation of the first, second and third motors to cause said drill bit to shape the blank to form a lens of the desired geometry.
