Abstract
An oscillating signal light mechanism is comprised of at least one signal light assembly mounted on a base for rotation of the light assembly relative to the base, a source of motive power including an output shaft selectively rotated in opposite directions of rotation, and a mechanism mechanically connecting the output shaft to the signal light assembly for converting the rotation of the output shaft in opposite directions of rotation to cycling movements of the signal light assembly through two different arc segment oscillations.
Claims20
A signal light assembly comprising:
- a signal light;
- a source of motive power having an output shaft that is selectively controlled to rotate in opposite first and second directions of rotation;
- and,
- a mechanism connected between the output shaft and the signal light that moves the signal light in a first movement in response to rotation of the output shaft in the first direction, and moves the signal light in a second movement, different from the first movement, in response to rotation of the output shaft in the second direction, the first movement is an oscillating movement of at least two complete oscillations of the signal light through a first arc segment in response to complete rotation of the output shaft in the first direction and the second movement is an oscillating movement of at least two complete oscillations of the signal light through a second arc segment, different from the first arc segment, in response to complete rotation of the output shaft in the second direction.

- a signal light;
- a source of motive power having an output shaft that is selectively controlled to rotate in opposite first and second directions of rotation;
- a mechanism connected between the output shaft and the signal light that moves the signal light in a first movement in response to rotation of the output shaft in the first direction, and moves the signal light in a second movement, different from the first movement, in response to rotation of the output shaft in the second direction;
- and,
- the mechanism includes a cam having a first axis and a cam surface, and a cam follower having a second axis and a pin engaging with the cam surface and having a pin axis, the cam is driven in opposite first and second directions about the first axis by rotation of the output shaft in the first and second directions, causing the follower to oscillate through different first and second arc segments about the second axis.
