Abstract
Two embodiments of automatic speed control devices for motorcycles that permits release of the device from automatic mode in response to throttle closing movement of the accelerator grip. In one embodiment, the release is effective by permitting a protective sheath of a wire actuator of the throttle mechanism to move in response to throttle closing movement of the accelerator grip and this movement is employed to actuate a switch. In another embodiment, a control wire and surrounding housing afford a switch that is closed when the accelerator grip is moved in a closing direction.
Claims16
In an automatic speed control for the internal combustion engine of a vehicle comprising a speed control element for the engine for controlling its speed, a manual speed control operatively connected to said engine speed control element for operator control of the engine speed, and an automatic speed control operatively connected to the engine speed control element and operable between an automatic condition for automatically maintaining a preset engine speed and an off condition wherein said automatic speed control is not operative for automatically maintaining preset engine speed, the improvement comprising means for operating said automatic speed control from its automatic condition to its off condition when said manual speed control is moved in a speed reducing direction.
In a switch mechanism for deactivating an automatic speed control for an engine speed control element comprising a wire actuator comprising a wire operatively connected to said speed control element for controlling the position of said element, a protective sheath encircling at least a portion of said wire, and means for retaining said protective sheath in position, the improvement comprising means for permitting movement of said protective sheath upon the application of a control pressure to said engine speed control element, and switch means responsive to movement of said protective sheath for deactivating said automatic speed control or the like.
An automatic speed control for the internal combustion engine of a vehicle comprising a speed control element for the engine for controlling its speed, a manual speed control, means providing a closed loop operative connection between said manual speed control and said engine speed control element for operator control of the engine speed in response to movement of said manual speed control in either the throttle opening or throttle closing direction, said closed loop operative connection comprising a throttle closing control wire and a throttle opening control wire each operatively connected at its respective ends to the respective control, an automatic speed control operatively connected by a wire actuator to the engine speed control element for automatically maintaining a preset engine speed, the operative connection between said automatic speed control and said engine speed control element including means for permitting movement of said engine speed control in at least one direction relative to said automatic speed control.
