4 Claims.

es to razors and particularly to a motor operated razor of simple construction and great utility.

It is an object of this invention to provide a the necessity of using soap or other lathers and like` materials in shaving.

A further object is to provide novel means for the cutting of hair from the surface human body.

of the Another object is to provide a device of this character which is self sharpening, thus ,dis-

pensi-ng with the necessity of changing blades or removing blades for external sharpening as is the case with the ordi at the present time.

nary type of razor in use WithA these and otherA objects in view', the

invention consists in certain novel features of construction, and combinations of parts as will be more fully hereinafter described and claimed.

My invention is illustrated in the accompanying drawing, which forming part of this application, in

Figure 1 is an elevation of the completely assembled device,

Figure 2 is a plan view of the same, Figure 3 is a sectional view taken on line 3-3 of Figure 1, v

Figure 4 and Figure 5 are enlarged fragmentarylviews of details of construction, hereinafter to be more fully described,

Figure 6 is a sectional View of Figure 3,

Figure 7 is vof Figure 6, and

Figure 8 taken on line 6-6 a sectional View taken on line 77 is an enlarged sectional view taken ysubstantially along line 8--8 of Figure 1.

Referring to the drawing,

I have shown therein a mechanically operated razor having the usual flexible shaft and cable 10, a stationary handle 11, a base 12 attached thereto and having a U-shaped head 13 which forms a recess 14.

A revoluble shaft 15 connected to a suitable scurceof power is located within openings 16 and 17 in the head 13 Upon the end of the eccentric 18. Mounted and base 12 respectively. shaft is mounted an upon this eccentric and located within the recess 14 is a movable blade 19 having angular cutting teeth 20 and having slots 21 at opposite ends.

A U-shaped guide member 22 is slidably and revolubly mounted in a sleeve 23 at the rear of the head 13 and has slots 21. An arcuate located in the recess its ends 24 mounted in the tensioning spring 25 is 14 and bears against the head 13 and the blade 19, the shaft 15 passing through an opening 26`therein.

A stationary blade 27 having a sharpened edge 28 encloses the recess `14 and is held in place by suitable clips 29, the edge 28 coacting with the teeth 20 of the movable blade.

In operation, the razor is used in the ordinary manner, the .shaft 15 causing a rotary movement to be imparted to the blade 19, the teeth 20 of which take up the hair and force it against the cutting edge 28 of the stationary'blade 27, the guide member 22 coacting with the slots 21 to keep the blades. parallel.

I have found that the use, of my device dispenses with the need of any lather whatsoever' -and have also noted that the spring 25 causes a grinding together of the blades 19 and 27, thus giving a self-sharpening razor.

Various slight changes might'be made in the general form and arrangement of parts described without departing from the invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. A'razor having a straight edged stationary blade, an eccentrically operated superposed revoluble blade having inclined teeth coacting in frictional contact with they stationary blade, means for extending the teeth over the edge of the stationary blade during a part of each revolution of the movable blade and for retracting them therefrom during the remainder of each revolution, means for maintaining parallel relationship between the blades, resilient means for holding the blades in frictional contact and a frame for holding the various parts in cooperative relationship.

2. A razor having a straight edged stationary blade, a movable blade provided with inclined teeth in frictional contact with the stationary blade, a'n eccentric for imparting a rotary motion to the movable'blade in the direction of inclination of the teeth and for extending and retracting the teeth with respect to the stationary blade, means for maintaining parallel relationship between the blades, resilient means for holding the blades in frictional contact with each other and a 4frame for holding the component parts in cooperative relation.

3. A razor having aV stationary blade with a straight cutting edge, a movable blade having inclined teeth coacting in frictional contact with 4. A razor having a stationary straight edged blade and a movable blade having inclined teeth, the inner edges of the teeth forming cutting edges which coact in frictional contact with the edge of the stationary blade, means for causing the teeth to alternately project over and recede from the cutting edge of the stationary blade while in motion, resilient means for maintaining i'rictional contact between the blades and a frame for holding the component parts in cooperative relation.
