Title: Improvements in and relating to vibratory electric motors
IPC: H02K33/10
Filed: 1934-08-15
Abstract: 442,871. Oscillating motors. GOLDSCHMIDT, R., 35, Clifton Court, St. John's Wood, London. Aug. 15, 1934, No. 23590. [Class 35] A vibratory electric motor for operating razors &e. comprises a body portion 1 attached to the member to be set in vibration and mounted upon it an armature 4 which can vibrate about an axis passing through or near the centre of gravity. The body 1 which as shown constitutes a casing and is of magnetic material, is also set in vibration and actuates the razor or other implement. The effective mass of the member 1, that is the mass of the body together with that of the attached apparatus (including the skin of the hand holding the body) is not more than three times that of the armature and is preferably equal thereto. The armature is pivoted at 2 in the casing and biassed to the central position by a weak spring 9. The spring may be omitted by clamping the spindle which is therefore twisted during vibration. The armature polepiece 7 is provided with a resilient hammer 8. The interrupter in the circuit of the armature coils 5 comprises a flat spring 10, Fig. 3, secured to the portion 6 of the armature and carrying at its free end a contact 13 engaging a second contact 14 carried by a stiff blade 15. The contacts are in sliding engagement in such a way that the circuit is closed during the greater part of the movement of the armature in one direction and open during the greater part of the movement in the other direction. The natural frequency of vibration of the contact 13 is usually much lower than that of the armature. The razor or other implement is clamped to the casing at 17, 18 so as to vibrate with it. Alternatively, the implement may be held in a clamp resiliently mounted on the casing opposite the point of impact of the hammer 8 so that vibrations are transmitted thereto without vibrating the casing appreciably. The mass of the casing therefore may be increased by the inclusion of a battery.
