Abstract
Abstract An improvement which converts an electric shaver into a stimulator for producing vibrations to stimulate the skin of the user. An oscillating member is provided in a portion of the shaver housing together with means for coupling the oscillating member to the motor of the shaver for driving the oscillating member to produce vibrations of an external shaver surface for stimulating the skin. In one embodiment the oscillating member is a vibrating bar having a surface available on the outside of the shaver, and in another embodiment the oscillating member is an eccentric weight inside the shaver which vibrates the shaver housing so that the housing itself can be applied to the skin to stimulate it. The vibrations may also stimulate muscle and flesh.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
166 words
In an electric shaver having an electrical motor within a shaver housing, the improvement comprising an oscillating member in a portion of said housing, and means for coupling said oscillating member to said motor for driving said oscillating member to produce vibrations of an external shaver surface for stimulating the skin of the user, said oscillating member comprising an eccentrically mounted rotary weight inside the housing, and said coupling means comPrising a clutch member engageable with said weight and rotated by said motor to drive said weight, and an actuator for engaging and disengaging said weight and said clutch member, said actuator including a button movably mounted on the exterior of said housing for manual actuation, a first wedge engaging said weight, and a second wedge movable laterally by said button to move said first wedge and said weight axially for engaging said weight and said clutch member, said first and second wedge members having mutually engaging slanting surfaces for coacting to shift said weight axially.
Claim 2
Dependent Claim
166 words
In an electric shaver having an electrical motor within a shaver housing, the improvement comprising an oscillating member in a portion of said housing, and means for coupling said oscillating member to said motor for driving said oscillating member to produce vibrations of an external shaver surface for stimulating the skin of the user, said oscillating member comprising an eccentrically mounted rotary weight inside the housing, and said coupling means comPrising a clutch member engageable with said weight and rotated by said motor to drive said weight, and an actuator for engaging and disengaging said weight and said clutch member, said actuator including a button movably mounted on the exterior of said housing for manual actuation, a first wedge engaging said weight, and a second wedge movable laterally by said button to move said first wedge and said weight axially for engaging said weight and said clutch member, said first and second wedge members having mutually engaging slanting surfaces for coacting to shift said weight axially.
Claim 3
Dependent Claim
29 words
The electric shaver improvement as claimed in claim 1 in which said wedges have dovetailed portions whereby reverse actuation of said button disengages said clutch member and said weight.
Claim 4
Dependent Claim
25 words
The electric shaver improvement as claimed in claim 2 in which said wedges are confined by a frame to guide the movement of said wedges.
Claim 5
Dependent Claim
25 words
The electric shaver improvement as claimed in claim 3 in which said button is a portion of said second wedge which projects through said housing.
