To all whom it may concern:
Be it known that I, George W. Lishawa, residing at Hartwell, Hamilton county, State of Ohio, have invented certain new and useful Improvements in Safety-Razors, of which the following is a clear, full, and exact description, attention being called to the drawing which accompanies this application and forms a part thereof.
This invention concerns shaving implements of the safety razor type.
In using a razor it is considered of advantage to bring the cutting blade as close as possible to the medium from which the action and directing movement proceeds.
This medium is the user's hand and the fingers thereof.
The object of my invention is to provide certain new and improved means whereby the blade-holding devices may be held directly by the hand of the user, so that the action of the hand is transferred in the most direct and positive manner to the blade.
The invention consists of these particular means and their construction as the same is hereinafter described and pointed out in the claims.
The invention is also illustrated in the accompanying drawing in which:
In the drawing letter
The shaving blade held as described is attached to the hand, respectively to one of the fingers thereof, by means of two clamping arms
The use of the implement is illustrated in
The two cutting edges are available, that is strokes may be applied in opposite directions, up and down for instance, without requiring changes in position of the implement or of the hand beyond such which are due to the motion of the hand.
Having described my invention, I claim as new :
1. In a shaving implement, the combination of a back-plate and of a cap-plate, both curved transversely in the same direction, means for holding one to the other, a flat spring-plate having opposite cutting edges adapted to occupy a position between the plates and forced into a constrained position by them when said plates are connected to each other, thereby serving to maintain the engagement of the means whereby said plates are held to each other and curved spring-arms projecting outwardly from opposite edges of the back-plate for clasping the implement upon one of the fingers of the user.
2. In a shaving implement, the combination of a cap-plate having lugs on one side thereof, a double-edged shaving blade adapted to be superposed thereon and provided with notches in its ends adapted to clear these lugs, a back-plate provided with openings to receive these lugs to be engaged by them after superposed upon the shaving blade and curved finger-clasping arms projecting from opposite edges of the backplate for mounting the implement upon one of the fingers of the user.
3. In a shaving-device, the combination of a double-edged shaving blade, a back-plate, means for holding the shaving blade to the back-plate and finger-clasping arms projecting outwardly from opposite edges of the backplate and curved toward each other with their free ends in close approach, said arms having portions of them between their edges curved inwardly to engage the finger more closely and to conform to the shape of the same.
In testimony whereof, I hereunto affix my signature.
George W. Lishawa.
