Optically guided power sabre saw
First Claim
1. An optically guided power sabre saw using a penciled or an inscribed line to follow, comprising:
- (a) a housing;
(b) a base plate attached to and displaced a distance from said housing, a right vertical support and a left vertical support both being disposed said distance and connecting said base plate to said housing;
(c) internal drift correcting means disposed internally to said housing and including a saw blade having reciprocating motion so that the penciled or inscribed line followed by said saw blade during the cutting process is automatically corrected; and
(d) external drift correcting means disposed externally to said housing and on said base plate and including a right photoresistor and a left photoresistor so that as said saw blade travels along said penciled or inscribed line, any drift off said penciled or inscribed line would be detected by said right and said left photoresistors and instantly fed back to said blade drive motor for said saw blade correction.
