Magnetically actuated vibrator

Claim 1

A therapeutic apparatus, particularly for the physical treatment of portions of the human body, comprising, a body having opposite ends and being formed of magnetic material; a pair of extensions respectively provided on said opposite ends of said body and extending transversely to the latter, said extensions having free ends arranged to be applied to the portions of the human body to be treated; a plurality of insulated windings wound about said body of magnetic material; means connected to said windings for applying an alternating current thereto; an armature located adjacent each extension; and a resilient metal lamina attached at one end to each extension and carrying at the other end thereof the respective armature, said metal lamina yieldably holding the respective armature spaced from the respective extension so that upon energizing said windings by an alternating current the armatures will be alternatively magnetically attracted into engagement with the respective extension and repelled by the action of the lamina to thus vibrate the extensions, whereby upon application of the apparatus to portions of the human body, the latter will be subjected to the alternating field extending between the free ends of said extensions and the vibrations of the latter.
