Gravitonic Life Ray Table

The Gravitonic Life Ray Machine is a therapeutic device, invented by Fred W. Reed and manufactured by his Gravitonic Life Ray Estate during the 1930s. According to Reed, the device harnessed, as the name suggests, what he called gravitonic life rays, a theretofore unknown form of vital energy, which was derived from "the forces of gravity, the tonic of the air, and the vibrational impulses in the ether surrounding the earth."
