Abstract

At least two motor drive means drives a control means for an appliance, each of the motor drive means including a speed reducing means coupled to a common output means which in turn is coupled to the control means.

Claims

1. In combination, an appliance, a control means selectively operating said appliance, said control means including cam programming means, two motor drive means driving said cam programming means through a common output means coupled to said drive means, one of said motor means continuously energized during the operation of said cam programming means, the other of said motors selectively energized to rapidly advance said cam programming means during said operation.

2. The combination according to claim 1 wherein said motor drive means includes synchronous motors.

3. The combination according to claim 1, further including separate speed reducing means each cooperatively associated with one of said motor drive means disposed within a housing means and wherein said common output means extends through said housing means on one side thereof, and said two motor drive means are disposed in juxtaposition on said housing means.

4. The combination according to claim 3 wherein said speed reducing means includes clutch means selectively coupling said two motor means with said output means.

5. The combination according to claim 4 wherein said clutch means is carried by said common output means.

6. In combination, an appliance, a control means selectively operating said appliance, said control means including cam programming means, two motor drive means driving said cam programming means through a common output means coupled to said drive means, one of said motor means continuously energized during the operation of said cam programming means, the other of said motors selectively energized to rapidly advance said cam programming means.

7. The combination according to claim 6 wherein said motor drive means includes synchronous motors.

8. The combination according to claim 6 further including separate speed reducing means each cooperatively associated with one of said motor drive means disposed within a housing means and wherein said common output means extends through said housing means on one side thereof, and said two motor drive means are disposed in juxtaposition on said housing means.

9. The combination according to claim 8 wherein said speed reducing means includes clutch means selectively coupling said two motor means with said output means.

10. The combination according to claim 9 wherein said clutch means is carried by said common output means.

11. In combination, an appliance, a control means selectively operating said appliance, and two synchRonous motors driving said control means and disposed in juxtaposition on a housing means each of said motors having a speed reducing means disposed within said housing means and coupled thereto, said speed reducing means coupled to a common output means coupled to said control means and extending through said housing means on one side thereof, said speed reducing means including a clutch means selectively coupling said motors with said common output means, and wherein said speed reducing means includes a gear train means enclosed in said housing means, said motors each including a wire wound enclosure comprised of a tubular section terminating in flanges and resilient stud means integrally formed with one of said flanges and extending therefrom, said housing means including apertures corresponding to said stud means, said stud means having flanged portion that extends beyond the corresponding aperture in said housing means, each of said stud means being adapted to be received in said corresponding aperture in said housing means and engaging with said housing means in locking relationship thereby effectively securing said gear train means to said synchronous motor so that the pinions of said synchronous motors are predeterminately and automatically aligned and cooperatively associated with the input gear of each of said gear trains.

12. A drive means comprising at least two motor means disposed in juxtaposition on a housing means, each of said motor means having a speed reducing means disposed within said housing means and coupled thereto, and clutch means selectively coupling said speed reducing means to a common output means extending through said housing means, said speed reducing means including a gear train means enclosed in said housing means, said motor means including synchronous motors each including a wire wound enclosure comprised of a tubular section terminating in flanges and resilient stud means integrally formed with one of said flanges and extending therefrom, said housing means including apertures corresponding to said stud means, said stud means having a flanged portion that extends beyond the corresponding aperture in said housing means, each of said stud means being adapted to be received in said corresponding aperture in said housing means and engaging with said housing means in locking relationship thereby effectively securing said gear train means to said synchronous motors so that the pinions of said synchronous motors are predeterminately and automatically aligned and cooperatively associated with the input gear of each of said gear trains.
