Patents by Inventor Bill Farmer

Bill Farmer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Electro-mechanical actuator
    Patent number: 7140151
    Abstract: An electro-mechanical actuator for a window lift mechanism including a plurality of motors for driving an output shaft. The actuator may be incorporated into a window lift mechanism including a dual rack and pinion assembly, for driving the pinions along the racks. According to another aspect of the invention there is provided a variety of anti-back-drive mechanisms, e.g. clutches. A clutch according to one embodiment includes locking pawls that resist back-drive. In another embodiment, locking cams rotate relative to a carrier to resist back-drive. An actuator consistent with the invention may incorporate an impact mechanism including a flexible carrier. The carrier flexes to prevent impact forces at an output gear train from coupling to an input gear train.

  • Electro-mechanical actuator and clutch for the same
    Patent number: 6557688
    Abstract: An actuator including a plurality of mounts for facilitating connection of the actuator to a variety of mounting bracket configurations for securing the actuator within an assembly. Also provided is a clutch assembly including an input member, an output member and pawls. Torque is transferred through the clutch when applied to the input member in a clockwise or counter-clockwise direction. When torque is applied to the output member, the clutch permits rotation in only one direction of rotation.
