‘Another object of our invention is to produce a scalp-massage device which will be in the form of a spherical or spheroidal segment and so shaped and proportioned in relation to the human cranium that the latter will guide the movement of the same
backwardly and forwardly in an arcuate path and such movement will cause the simultaneous massaging of the skin covering the frontal, parietal, temporal and occipital portions of the cranium without contact with the ears of the ” person massaged.”‘
