Abstract
An oscillating signal light mechanism producing substantially constant angular velocity oscillation cycles of a single light 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 rotated at a constant velocity in a single direction of rotation, and a mechanism mechanically connecting the output shaft to the signal light assembly for converting the constant velocity single direction rotation of the output shaft to cycling movements of the signal light assembly through arc segment oscillations at substantially constant angular velocity.
Claims20
An oscillating signal light apparatus producing signal light oscillations through an arc segment of movement of the signal light, the apparatus comprising:
- a base;
- at least one signal light assembly mounted on the base for rotation of the light assembly relative to the base;
- a first pulley operatively connected to the light assembly;
- a second pulley mounted on the base for rotation of the second pulley relative to the base;
- a belt looped around at least the first and second pulleys for converting linear movement of the belt to rotating movement of the first and second pulleys;
- a source of motive power including an output shaft rotated in a single direction of rotation;
- and,
- means operatively connecting the belt to the source of motive power for producing linearly reciprocating movement of the belt in response to the single direction rotation of the output shaft.
