To all whom it may concern:
Be it known that we, Winfred H. Van Gorder and Christian E. A. Gronbech, citizens of the United States of America, residing, respectively at Brooklyn, county of Kings, State of ew York, and Woodhaven, Long Island, county of Queens, and State of New York, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.
Our invention relates to improvements in safety razors.
Safety razors as ordinarily constructed include a handle which projects at right angles to the plane of the razor from the middle thereof and usually serves not only as a handle but also as means to secure the blade between a base plate and a clamping plate. A razor of this construction occupies considerable space, and one object of our invention is to provide a safety razor which can be folded into so small a compass that it maybe conveniently slipped into a vest pocket and carried about.
In safety razors in general use the sides or sharpened edges of the blade project beyond the clamping plate and these edges may readily come into contact with objects which damage or dull them. Another object of our invention is to so construct the razor that the parts which form the handle thereof may be folded when the razor is out of use to cover the sharp edges of the blade and protect the same against injury.
Another object of the invention is to provide means for retaining the blade in laterally adjusted position so that the cutting edge of the blade will be exposed to a greater or less extent in order to regulate the closeness of the shaving action.
Generally stated, the improved razor comprises a base plate and a clamping plate movably connected together, and handle members which are capable of being moved into a position to fold against the body of the razor and preferably cover the cutting edges of the blade.
The preferred embodiment of the invention is illustrated in the accompanying drawing, in which—
Referring to the drawing,
Also mounted on the pintle

The width of the clamping plate
The device may be manipulated as follows:—Assuming the parts to occupy the positions of
During shaving the user will press more or less tightly against the handle members
The device has many advantages over existing types of safety razors as will readily appear from the foregoing description and the accompanying drawing. It is also to be noted that the outer face of the base plate
It is to be understood that our invention is not limited to the details herein shown and described, as modifications will readily suggest themselves to those skilled in the art, without departing from the spirit of the invention as defined by the scope of the appended claims.
1. A safety razor comprising a base plate plate, movably interconnected and handle members movably mounted at opposite ends of the clamping plate and capable of being folded to overlie the body of the razor.
2. A safety razor comprising a base plate, a clamping plate pivoted to one end thereof, and a handle pivoted to said clamping plate and capable of being folded to overlie the body of the razor.
3. A safety razor comprising a base plate, a clamping plate pivoted to one end thereof, and like handle members pivotally mounted at opposite ends of the clamping plate, each of said handle members being adapted to be folded down over the clamping plate and cover approximately one half thereof.
4. A safety razor comprising a base plate, a pintle at one end thereof, a clamping plate mounted on said pintle, a handle member also mounted on said pintle, and a second handle member movably carried at the other end of said clamping plate.
5. A safety razor, employing a movable blade, comprising a base plate having a complemental clamping plate movably interconnected with one end of said base plate, handle members hinged at opposite ends of said clamping plate, and means whereby the cutting edge of said blade may be adjusted in relation to the base plate when the handles are extended, said means permitting the handles being folded to overlie the body of the razor when the latter is in closed position.
6. A safety razor, employing a flat blade, comprising a base plate and a clamping plate adapted to hold said blade between the upper surface of said base plate and the inner surface of said clamping plate, handle members movably mounted at opposite ends of the clamping plate, said handles having offset hinges adapted to provide a shoulder contacting with the under side of the base plate when in open position, thereby exerting a varying clamping action of the clamping plate, against the blade resting upon the base plate depending on convergence of the handles.
7. A safety razor comprising a base plate, a clamping plate pivoted to one end thereof, a flat flexible blade adapted to be adjustably held therebetween, like handle members having offset pivot hinge portions adapted to be pivotally mounted at opposite ends of the clamping plate, each of said handle members being adapted to be folded down over the clamping plate covering approximately half thereof when in closed position and compressing shoulders forming part of each offset hinge being adapted when extended to be folded against the back of said base plate drawing the clamping plate nearer to the base plate relative to the convergence of the handles.
In testimony whereof we have affixed our signatures in presence of two witnesses.
