To all whom it may concern:
Be it known that I, John K. Joice, a citizen of the United States, and a resident of Chicago, Cook county, Illinois, have invented a certain new, useful, and Improved Automatic Razor, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in razors and has particular reference to improvements in razors of that class known as “safety” razors.
The object of my invention is to provide a razor which may be used without special skill on the part of the person who is shaving himself, in other words, a razor of the “safety” type.
A further and particular object of my invention is to provide a razor which shall be automatic in action, that is to say, a device in which the cutting blade shall be moved with great rapidity; so that to do its proper work the device need only be held against the face and moved slowly thereon, the user being relieved from the necessity of exercising special care or skill in the manipulation of the razor.
My invention consists generally in an automatic razor which comprises a knife guard, having a suitable handle, in combination with a knife or blade arranged for reciprocation in said guard and means for rapidly reciprocating said knife.
Further, my invention consists in an automatic razor comprising a knife guard having a handle, in combination with a razor blade arranged for movement in said guard and a suitable motor provided in said handle and connected with said blade, for operating the blade in the guard.
Further, my invention consists in the combination of a razor blade with a casing or guard therefor and an electro magnetic mechanism for actuating said blade.
The invention also consists in various details of construction and in combinations of parts, all as hereinafter described and particularly pointed out in the claims.
The invention will be more readily understood by reference to the accompanying drawings; forming a part of this specification, and in which :—
In carrying my invention into effect, I prefer to employ a handle,
The handle,
In constructing my novel device, I prefer to use an electro-magnetic motor for actuating the razor blade or knife. I have herein shown a reciprocating electro-magnetic motor for this purpose, the same comprising a solenoid,
The coil of the solenoidal motor shown in
The circuit closer,
The end of the core,
In
The device shown in
The use and operation of my automatic razor is extremely simple. When the face has been lathered and is in readiness for the razor, the user simply grasps the handle and places the razor guard against his face. He then depresses the circuit closer,
As numerous modifications of the structure herein shown and described will readily suggest themselves to one skilled in the art, I do not confine my invention thereto.
Having thus described my invention I claim as new and desire to secure by Letters Patent:
1. In an automatic razor, a suitable “safety” guard, in combination with a razor blade, mounted for reciprocation in said guard, a suitable motor connected to said blade and means for varying the stroke of said blade, substantially as described.
2. In an automatic razor, a suitable safety guard, in combination with a razor blade, mounted therein a motor connected with said blade and means for varying the stroke of said motor, substantially as described.
3. In an automatic razor, a suitable “safety” guard, in combination with a motor casing therefrom, a motor arranged in said casing, an elastic diaphragm, interposed between said guard and said casing, and a razor blade arranged in said guard and connected to said motor, substantially as described.
4. In an automatic razor, a suitable “safety” guard or hood, in combination with a reciprocating motor, a toggle lever mechanism connected to said motor and a razor blade arranged in said guard, for actuation by said mechanism, substantially as described.
5. In an automatic razor, a suitable handle, in combination with a guard plate thereon, angularly positioned guides on said plate, a blade-carrier mounted in said guides, a motor mechanism connected with said carrier and a razor-blade, on said plate, substantially as described.
6. In an automatic razor, a suitable “safety” guard, in combination with a knife carrier, mounted for reciprocation in said guard, lugs near the outer edge of said carrier and a knife blade having openings near its edge and engaged with said lugs, substantially as described.
7. In an automatic razor, a suitable guard, in combination with a razor blade mounted therein, a motor for reciprocating said blade, and guides angularly arranged in said guard for directing the movement of said blade; substantially as described.
8. In an automatic razor, a suitable safety guard, in combination with angularly arranged guides therein, a blade carrier mounted upon said guides, a blade secured to said carrier, and a suitable motor for actuating the same; substantially as described.
9. In an automatic razor, a suitable guard, in combination with a knife arranged, for reciprocation therein, an elongated handle attached to said guard and at substantially right angles to the plane of reciprocation of said knife, a knife driving shaft in said handle, suitable connection between said shaft and said knife, and means for moving said shaft longitudinally to impart reciprocation to said knife; substantially as described.
10. In an automatic razor, a suitably attached handle and guard, in combination with a knife arranged in said guard, a knife driving shaft in said handle, means for imparting longitudinal reciprocation to said shaft, and means connecting said shaft and knife whereby motion of the former imparts reciprocation to the latter, substantially as described.
11. In an automatic razor, a suitably attached handle and guard, in combination with a knife arranged in said guard, a knife driving shaft in said handle, suitable connection between said shaft and said knife, and means for moving said shaft longitudinally to impart reciprocation to said knife, substantially as described.
In testimony whereof, I have hereunto set my hand, this 31st day of January, 1906, in the presence of two subscribing witnesses.
John K. Joice.
