  • Patent number: 4024828
    Abstract: This invention is for a portable signaling device which provides the user with the ability to accurately position the device in a manner to be assured that the reflections from the mirror-like surface forming a part of the signaling device are directed at the target. The signaling device includes signaling means having a plate with a surface to reflect the rays of the sun and sighting means maintained in spaced relation to the signaling means. An aperture is provided on the signaling means and the sighting means through which the user can view the target to obtain proper alignment and in turn maximum reflection from the mirror-like surface to the target. In addition, the reflective surface of the signaling means includes a set of cross hairs which are adapted to be reflected onto the sighting means such that the reflective set of cross hairs can be maintained in alignment with the aperture on the sighting means to maintain a proper alignment therebetween for maximum transmission of the signal to the target.
