To all whom it may concern:
Be it known that I, Charles J. Kiefer, of Tiffin, in the county of Seneca and in the State of Ohio, have invented a certain new and useful Improvement in Safety-Razors, and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which—
The object of my invention is to provide a safety razor which may be successfully used upon all portions of the face, notwithstanding the great variety of conditions presented due to the almost infinite variation of features and facial formations, and to provide a safety razor of as few parts as possible, and one in which the assemblage and separation of the parts may be done very conveniently and most expeditiously, and to these ends my invention consists in the safety razor constructed substantially as hereinafter specified and claimed.
In constructing a safety razor in accordance with my invention, I employ a blade
A laterally extending arm
To add to the convenience of manipulation of the parts in assembling and separating them, the lug or stud is slightly elongated or projected outward, and its surface roughened, so that when it is desired, for example, to unlatch the parts, the assembled plates and blade may be grasped by the thumb of one hand engaging said lug and the forefinger engaging the outer plate, and the handle being taken by the other hand, the latch arm or bar may be disengaged from the boss or projection
While I prefer to construct my razor with all the features I show and describe, it will be understood that razors may be constructed which will embody my invention even though in one razor there may not be contained all the features herein shown and described, and the scope of my patent is to be determined in the light of this statement.
Having thus described my invention, what I claim is—
1. In a safety razor, the combination of a blade, a blade-supporting plate, a handle pivotally connected to said plate, a blade clamping plate, and a holding arm attached to and moving with the handle and engaging said clamping plate on the side opposite that engaging the blade.
2. In a safety razor, the combination of a blade, a blade supporting plate, a post projecting from said plate having a shoulder, a holding arm rotatably mounted on the post, a handle carrying said arm and a blade-clamping plate engageable by said arm.
3. In a safety razor, the combination of a blade, plates on opposite sides thereof, a post projecting from one of said plates, and having a shoulder, and an arm to hold said parts together, rotatably mounted on said post on the inner side of the shoulder and movable into and out of contact with the plate not provided with the post.
4. In a safety razor, the combination of a blade, plates on opposite sides thereof, and means to hold said plates together comprising a connected handle and arm rotatably connected with one of said plates, the arm engaging the other plate at a point eccentric to its center of rotation.
5. The combination of a blade holder, comprising blade-clamping members, a pivoted arm and holding means for said arm comprising interlocking surfaces eccentric to the center of motion of the arm, the swinging movement of the arm being relative to the blade-clamping members.
6. The combination of a blade holder, comprising blade-clamping members, a pivoted arm and holding means for said arm comprising an arm-engaging recess in a part stationary relative to the arm, and located eccentrically to the center of motion thereof, the swinging movement of the arm being relative to the blade-clamping members.
7. The combination of a blade holder comprising blade-clamping members, a pivoted arm and holding means for said arm comprising an arm-engaging recess in a part stationary relative to the arm, and located eccentrically to the center of motion thereof, and means holding the arm in engagement with the recess, the swinging movement of the arm being relative to the blade-clamping members.
8. The combination of a blade holder comprising blade-clamping members, a pivoted arm and holding means for said arm, comprising interlocking surfaces eccentric to the center of motion of the arm, the arm being movable in a direction at right angles to its swinging movement to cause the engagement and disengagement of said interlocking surfaces, the swinging movement of the arm being relative to the blade-clamping members.
9. A safety razor comprising a blade, and clamping plates that engage opposite sides of the blade, whose surfaces in contact therewith are respectively concave and convex in a direction lengthwise of the blade, forming a cutting edge that is curved lengthwise of the blade the convex portion of the curve being applied to the surface to be shaved, and means to hold said parts together.
10. A safety razor comprising a blade, and clamping plates that engage opposite sides of the blade, whose surfaces in contact therewith are respectively concave and convex in a direction lengthwise of the blade, forming a cutting edge that is curved lengthwise of the blade, and means to hold said parts together, comprising a spring latch bar and a bar-engaging shoulder.
11. In a safety razor, the combination of a blade, a supporting plate, a post having a shoulder, locking arm rotatably mounted on the post between the post shoulder and the supporting plate, and a blade engaging clamping member between said locking arm and the blade.
12. In a safety razor, the combination of a blade, plates on opposite sides thereof, a post projecting from one of said plates through openings in the blade and the other plate, and having a lug or shoulder, a bar to hold said parts together, rotatably mounted on said post and coacting with said shoulder, and a handle from which said bar projects.
13. In a safety razor, the combination of a blade, plates on opposite sides thereof, the surfaces of said plates engaging the blade being respectively concave and convex, and the blade being thereby kept under tension to cause it to have a spring action, a post projecting from one of said plates through openings in the blade and the other plate, and having a lug or shoulder, and a bar to hold said parts together, rotatably mounted on said post and coacting with said shoulder.
14. In a safety razor, the combination of a blade, plates on opposite sides thereof, the surfaces of said plates engaging the blade being respectively concave and convex, and the blade being thereby kept under tension to cause it to have a spring action, a lug on one of said plates, notches in the blade and the other plate to engage said lug, a post projecting from one of said plates through openings in the blade and the other plate, and having a lug or shoulder, and a bar to hold said parts together, rotatably mounted on said post and co-acting with said shoulder.
In testimony that I claim the foregoing I have hereunto set my hand.
