Abstract: "A torus model of the elementary particles is suggested in which the electron and proton are made stable by gravitational forces derived from the electromagnetic field. It is suggested that the gravitational forces for the unstable particles, presumably the mesons, are not sufficient to keep the torus from expanding in the direction of its large radius. Rest energy zero can be achieved, presumably for photons and neutrons, when the gravitational energy and electromagnetic field energy are equal in magnitude. The manner in which these models can exhibit spin, magnetic moment, wave length, and phase velocity is indicated. The origin of nuclear forces from an electromagnetic basis is indicated."
