Abstract

In accordance with the invention, a drill comprises a drill housing with a handle portion and a driver portion. A push button battery tester extends battery life. An electrical drill motor is located in the driver portion. The drill motor has an output shaft for coupling output rotary power. An electrical switch controls the operation of the drill motor. The electrical switch it is located on the handle portion of the drill housing. A chuck is coupled to the output shaft of the drill motor.

Claims

1. A drill, comprising:

(a) a drill housing comprising a handle portion and a driver portion;

(b) an electrical drill motor located in said driver portion, said drill motor having an output shaft for coupling output rotary power;

(c) an electrical switch for controlling the operation of said drill motor, said electrical switch being located on said handle portion of said drill housing;

(d) a chuck coupled to the output shaft of said drill motor;

(e) charge state measuring circuitry having a plurality of output terminals, actuation of said output terminals or combination of output terminals each corresponding to a particular state of charge;

(f) a red indicator light coupled to one of said output terminals, said one of said output terminals indicating a relatively poor state of charge;

(g) a green indicator light coupled to one of said output terminals, said one of said output terminals indicating a relatively good state of charge; and

(h) a charge test switch for actuating said charge state measuring circuitry.

2. Apparatus as in claim 1, wherein the charge state measuring circuitry further comprises an output terminal for driving a yellow light, and said charge state measuring circuitry i) actuates said yellow light to indicate a condition which is neither good nor poor, ii) actuates said green light and said yellow light simultaneously to indicate a battery charge condition that is better than that indicated by said yellow light but not as good as that indicated by said green light and, iii) actuates said red light and said yellow light simultaneously to indicate a battery charge condition that is worse than that indicated by said yellow light but not as bad as that indicated by said red light.

3. Apparatus as in claim 1, wherein said indicator lights are located on the left side of the handle portion of said drill housing.

4. Apparatus as in claim 1, further comprising a green directional indicator and a red directional indicator, said green indicator indicating movement in a clockwise direction and said red indicator indicating movement in a counterclockwise direction.

6. A drill as in claim 1, wherein a first workpiece illuminating light is provided on the left-hand side of the drill, and a second workpiece illuminating light is positioned on the top of driver portion of said drill.

5. A drill, comprising:

(a) a drill housing comprising a handle portion and a driver portion;

(b) an electrical drill motor located in said driver portion, said drill motor having an output shaft for coupling output rotary power;

(c) an electrical switch for controlling the operation of said drill motor, said electrical switch being located on said handle portion of said drill housing;

(d) a chuck coupled to the output shaft of said drill motor;

(e) charge state measuring circuitry having a plurality of output terminals, actuation of said output terminals or combination of output terminals each corresponding to a particular state of charge;

(f) a first charge state indicator light in a first color coupled to one of said output terminals, said one of said output terminals indicating a relatively poor state of charge;

(g) a second charge state indicator light in a second color coupled to one of said output terminals, said one of said output terminals indicating a relatively good state of charge;

(h) a third charge state indicator light in a third color coupled to one of said output terminals, said one of said output terminals indicating a state of charge better than that indicated by said second indicator light and not as good as that indicated by said first indicator light; and

(h) a charge test switch for actuating said charge state measuring circuitry, said the charge state measuring circuitry further comprising an output terminal for driving said third charge state indicator light, and said charge state measuring circuitry i) actuates said third charge state indicator light to indicate a condition which is neither good nor poor, ii) actuates said first charge state indicator light and said third charge state indicator light simultaneously to indicate a battery charge condition that is better than that indicated by said third charge state indicator light but not as good as that indicated by said first charge state indicator light and, iii) actuates said second charge state indicator light and said third charge state indicator light simultaneously to indicate a battery charge condition that is worse than that indicated by said third charge state indicator light but not as bad as that indicated by said second charge state indicator light.
