Fernan Conill, of New York, N. Y. Safety-Razor
1,208,491. Specification of Letters Patent. Patented Dec. 12, 1916.
Application filed April 22, 1916. Serial No. 92,910

To all whom it may concern:

Be it known that I, Fernan Conill, a citizen of the Republic of Cuba, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Safety-Razors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in razors, and the principal object of the invention is to provide a razor in which the blade is given a rapid transverse movement in order that the edge of the blade will have a sawing action when the razor is in use.

Another object of the invention is to provide a razor of the ordinary safety razor type provided with a novel means for causing the blade to reciprocate and for holding the blade against movement in a direction other than that in which it is required to move.

Still another object of the invention is to provide a motor driven blade which may be readily removed and replaced in the ordinary manner.

A still further object of the invention is to provide a guard plate for the blade which carries suitable projections forming bearings on which the blade is movable.

With these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawing, in which :—

Figure 1 is a horizontal sectional view through a razor constructed in accordance with this invention, showing portions thereof in elevation. Fig. 2 is a fragmentary side view in elevation of Fig. 1, and Fig. 3 is a detail view of the blade, showing the same in place on the razor, and illustrating in detail the connection between the blade and eccentric.

Referring to the drawing, the numeral 1 designates the handle of the device consisting of the outer sleeve 2, which supports at its forward end the head 3. This head 3 is transversely curved and extends from opposite sides of the handle and has formed near one end the bearing 4 in which the razor operating shaft is mounted. A central opening 5 is formed in the head and is adapted to receive the shank 6 of the guard plate which projects into the board 7 of the handle and is held in place by the inner rotating sleeve 8 formed with the enlargement 9 at its outer end. The inner end of the sleeve 8 is provided with internal screw threads for engagement with the threaded end 10 of the stem 6 of the guard plate, and it will thus be seen that the manipulation of the enlargement 9 will secure or release the guard plate. Formed near one end of the head 3 is an opening 11, which is positioned near the end opposite the one near which the extension 4 is formed, and this opening 11 is adapted to support the guide lug 12 of the guide plate, as clearly shown in the drawing. The guard plate is designated by the numeral 13 and consists of a transversely curved plate 6, as illus-rated in Fig. 2, which is formed on the end of the shank 6 and carries the lug 12, as clearly illustrated in the drawing. The eccentric bearing 4 is formed with a longitudinal bore 14, which opens at its outer end into an enlarged bore 15 and the opposite end of the bore 14 opens into the enlarged bore 16 in which the eccentric is operable.

Surrounding the handle 1 is a suitable sleeve 17, which is secured thereon in any suitable manner, and this sleeve supports the motor 18, the shaft of which is designated by the numeral 19. A universal joint 20 is provided at the forward end of the shaft 19 and forms a connection for the eccentric shaft 24 which is journaled in the opening 14. The forward end of the eccentric shaft extends slightly beyond the end of the bore 14 and carries the eccentric 22 which is operable in the slot in the blade, which will be more fully hereinafter described. The motor 18 is adapted to be connected to any suitable power source by means of the wire 23, and it will thus be seen that when the power is turned on the motor will be set in operation, thereby driving the eccentric shaft 21 and causing the eccentric 22 to revolve.

The blades used in connection with the device, designated by the numeral 24, consist of a thin water-like body provided at opposite side edges with cutting edges and formed centrally of the blade 24 is a longitudinal substantially rectangular aperture 25 through which the stem 6 of the guard plate 18 extends. A similar opening 26 is formed near one end of the blade and this opening is adapted to receive the lug 12, and it will be seen that when the device is assembled, as illustrated in Fig. 1, the blade will be free to move longitudinally, but lateral movement will be prevented by the stem 6 and lug 12. Formed near the end of the blade opposite the opening 26 is an opening 27, which is substantially rectangular but has its longitudinal axis disposed in a plane at right angles to the longitudinal axis of the blade and this opening 27 is of a width sufficient to receive the eccentric 22, so that upon rotation thereof the blade will be reciprocated longitudinally.

In use, it will be seen that the operation of the motor causes the shaft 21 to revolve, thereby revolving the eccentric 22 and causing the blade to reciprocate longitudinally and upon using the device in the ordinary manner it will be apparent that the blade will be drawn across the hair of the beard with a sawing action, thereby facilitating the act of shaving and causing the hair to be more readily cut.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the appended claim.

What is claimed is:

A safety razor comprising a handle, a transversely curved head at one end of the handle, said handle being provided with a bore, the head being provided with an opening near one end, a stem on the inner face of the head projecting in a plane parallel with the handle near the end opposite the opening, said stem being provided with a longitudinal bore, the rear end of the bore opening into an enlarged chamber, a transversely curved guard plate adapted for cooperation with the head, a stem on said guard plate extending into the bore in the handle, a lug on the guard plate extending through the opening in the head, means in the bore of the handle to hold the guard plate and stem in place, a longitudinally slidable blade positioned between the guard plate and the head, said blade having a central elongated slot and being provided with a similar opening near one end, said opening being disposed in a plane parallel with the longitudinal axis of the blade, the blade being provided with an elongated opening near its opposite end, the last-named opening being disposed in a plane at right angles to the longitudinal axis of the blade, an eccentric shaft mounted in the bore of the eccentric on the head, an eccentric at the outer end of the shaft positioned within the transverse opening of the blade, a sleeve surrounding the handle, a motor carried by the sleeve, a shaft for said motor, and a universal joint connecting the shaft with the eccentric shaft.

In testimony whereof I affix my signature in presence of two witnesses.

Fernan Conill.
