To all whom it may concern:
Be it known that I, Frederick D. Stitt, a citizen of the United States, residing in Carson, in Pottawattamie county, in the State of Iowa, have invented certain new and useful Improvements in Razors, and have described the same in the following specification, illustrated by the accompanying drawings.
The invention relates to that class of razors, sometimes called automatic, which individually comprise an electromagnet having a vibrating armature actuating the blade.
It is the object of the invention to render a razor of this class adjustable according to varying conditions and positions of the work to which it is applied; to vibrate the blade either transversely, or in any desired oblique direction relative to the direction in which the blade advances over the face or other skin surface to which it is applied; to bring the apparatus into active operation by merely applying the same to the work; to economize the consumption of current; and in genera] to increase the efficiency of razors of the specified class. To accomplish this object I incorporate in my improved razor, as parts thereof, an adjustable rigid connection between the reciprocating blade and the armature by which it is driven, and a circuit-breaker whose movable member is actuated to close the circuit by the reaction of the work.
In the accompanying drawings, illustrating the best manner in which I have contemplated applying the principles of the invention,
In the illustrated specimen of my invention, a one-piece iron frame, comprising the parallel top and bottom plates
When the instrument is not in operation, the circuit breaker is normally open as shown, and is held open by the position of the armature as affected by the residual attraction of the magnets. When by manipulation of the handle
By this construction and mode of operation the specified object of the invention is accomplished in all its branches.
I claim as my invention—
1. A razor of the specified class, comprising an electromagnet having an armature vibrating forward and backward; a blade-holder having a screw stem adjustably seated in the armature, means for adjusting the stem rotarily in its seat, and a circuit-breaker located in the circuit of the electromagnet and operated by the armature through the backward reaction of the work upon the blade-holder to close the circuit, and through the intermittent excitation of the electromagnet to open the circuit, in continual automatic alternation.
2. A razor of the specified class, comprising an electromagnet having an armature vibrating forward and backward; a blade-holder having a screw stem adjustably seated in the armature, means for adjusting the stem rotarily in its seat; a lock-nut on the screw stem, and a circuit-breaker located in the circuit of the electromagnet, and adapted to be opened by the action of the magnet and closed by the backward reaction of the work, in continual alternation.
3. A razor of the specified class, comprising an electric circuit, an electromagnet and a circuit-closer in the circuit, a vibrating blade-holder, and a pivoted armature actuating the circuit-closer and the blade-holder, and actuated by the blade-holder and by the electromagnet in continual alternation.
4. A razor of the specified class, comprising an electromagnet having a vibrating armature, a blade-holder having a rotarily adjustable stem carried by the armature, means for locking the stem to the armature in different positions of rotative adjustment, and a circuit-breaker operated by the movements of the armature to control the excitation of the electromagnet.
