Actuator having a rotational power source

An actuator comprising:

• (a) a drive motor having a gear;
• (b) a position sensor in side by side arrangement with said drive motor;
• and
• (c) a speed reducer having a gear which is engaged with said drive motor gear, said speed reducer also having an output shaft and a hollow input shaft through which said output shaft is extended to thereby drive said position sensor.

An actuator comprising:

• (a) a drive motor engaged with a speed reducer, said drive motor having a hollow shaft;
• (b) an assembly for manually adjusting said actuator by engaging said hollow drive motor shaft, said assembly comprising:
• (i) a shaft having a first end and a stub at a second end for engagement with said drive motor hollow shaft when a force is applied to said first end;
• and
• (ii) a compression spring mounted on said stub for disengaging said shaft stub from said motor drive hollow shaft when said applied force is removed from said first end.

An actuator comprising:

• (a) a drive motor having a gear;
• (b) a position sensor in side by side arrangement with said drive motor;
• (c) a cam disk having a first side which is flat and a second opposed side having a tapered ramp thereon, said second opposed side facing said position sensor, said position sensor in contact with said cam disk second side;
• and
• (d) a speed reducer having a gear which is engaged with said drive motor gear, said speed reducer also having an output shaft and a hollow input shaft through which said output shaft is extended, said extended output shaft connected to said cam disk to thereby cause motion of said cam disk when said actuator is energized.

An actuator comprising:

• (b) a position sensor in side by side arrangement with said drive motor;
• (c) a cam disk having a first side which is flat and a second opposed side having a tapered ramp thereon, said first side facing said position sensor, said position sensor in contact with said cam disk first side;
• and
• (d) a speed reducer having a gear which is engaged with said drive motor gear, said speed reducer also having an output shaft and a hollow input shaft through which said output shaft is extended, said extended output shaft connected to said cam disk to thereby cause motion of said cam disk when said actuator is energized.

An actuator comprising:

• (a) a drive motor having a gear;
• (b) a position sensor in side by side arrangement with said drive motor;
• (c) a cam disk having a first side having a predetermined shape and a second opposed side, said first side facing said position sensor, said position sensor in contact with said cam disk first side;
• and
• (d) a speed reducer having a gear which is engaged with said drive motor gear, said speed reducer also having an output shaft and a hollow input shaft through which said output shaft is extended, said extended output shaft connected to said cam disk to thereby cause motion of said cam disk when said actuator is energized.

An actuator comprising:

• (a) a drive motor having a gear;
• (b) a position sensor in side by side arrangement with said drive motor;
• (c) a cam disk having an opening therethrough and a first side having a predetermined shape and a second opposed side, said first side facing said position sensor, said position sensor in contact with said cam disk first side;
• (d) a drive block having an opening, said drive block residing in said cam disk opening;
• and
• (e) a speed reducer having a gear which is engaged with said drive motor gear, said speed reducer also having an output shaft and a hollow input shaft through which said output shaft is extended, said extended output shaft connected to said drive block opening to thereby cause motion of said cam disk when said actuator is energized.

A cylindrically shaped drive block for an actuator comprising:

• (a) a first cantilever leaf spring cut in said drive block;
• (b) a second cantilever leaf spring cut in said drive block;
• and
• (c) an opening at least partway therethrough.
