To all whom it may concern:
Be it known that we, François Durand, Eugene Louis Bossin, and Jean Jules Brard, all of Paris, in the Republic of France, have invented a new and useful Improvement in Razors, of which improvement the following specification is a full description.
The invention consists in the construction of razors in three principal parts, jointed to each other at the ends, so as to be folded, and thus occupy only a small space, or to be extended for use; and it further consists in the combination, with the blade of a razor or similar cutting-instrument, of a number of rollers supported by a suitable frame a slight distance beyond the edge; and also in an attachment for razors of the ordinary form or of the improved construction, constituting the first part of this invention, or of other suitable construction, and in the particular combination of parts, as hereinafter more fully set forth. When the three-part razor is extended for use the handle is of the usual long approved pattern. The three parts consist of a body or central section, a handle jointed thereto at one end, and a blade connected with the other end by a pivot.
In applying the rollers to this kind of razor they are attached to and carried by the body of the instrument. With razors of the ordinary construction the roller-frame is detachably connected with the blade, and it will be obvious that an attachment of this description could be applied also to the blade of a razor made in three parts, as indicated above. Means for adjusting the distance of the rollers from the edge of the blade are provided. The object of these rollers is to prevent the penetration of the blade into the flesh, and they also serve to keep the cutting-edge clear.
In order that the invention and the manner of carrying the same into effect may be fully understood, the same will now be more particularly described, in connection with the accompanying drawings, which form a part of this specification.
The same letters indicate like parts where they occur on all the figures.

The rollers carried by the adjustable frame, as on both sheets, prevent the cutting of the flesh, and in consequence of the rotation of the rollers and of the direction of this rotation the cut hairs and the lather of the soap are constantly carried off. The space between the rollers and the edge of the blade can never, therefore, become obstructed or clogged. In this respect the rollers are essentially different from a fixed plate or even a coil, as these do not facilitate the discharge of the matters referred to. The back of the razor-blade is rounded, and the faces hollowed slightly to aid the sharpening operation.
It will be seen that the roller-frame is adjustable, while the other parts are permanently connected.
In applying the attachment with rollers to an ordinary razor all that is necessary is to place the frame on the razor-blade and to cut away a portion of one of the sides of the handle.
Having now explained our said invention, and the manner in which the same is or may be carried into effect, what we claim, and desire to secure by Letters Patent, is—
1. A razor constructed in three principal parts:—to wit: a blade, a handle, and a body or central section, to which said blade and handle are hinged or jointed at the ends, substantially as described.
2. The combination, with the blade of a razor, of a series of rollers secured close to and slightly in advance of said blade by means of a supporting plate or frame of substantially the form shown and described.
3. An attachment for use in connection with the blade of a razor, consisting of a plate or frame of substantially the form shown, partly cut away, and having depending arms or projections, a shaft carrying a series of rollers, and supported by said plate or frame, and means, as set forth, whereby the said frame can be adjustably attached to the razor-blade, so that said rollers can be brought close to and slightly in advance of the cutting-edge, substantially as described.
4. The combination of a body or central section with a blade and handle jointed to said body or section, and a plate or frame carrying rollers adjustably secured thereto, substantially as described.
5. The combination, with the body or central section, handle, and blade of a three-part razor, of the spring and retaining-piece operating in connection with said blade, substantially as described.
