UNITEDI'STATES' PATENT OFFICE.

JOHN L. KING, OF CHICAGO, ILLINOIS, ASSIGNOR TO ROTARY KING SAFETY RAZOR COMPANY, A CORPORATION OF DELAWARE.

SAFETY-RAZOR.

My invention relates to razors of the class known as safety razors, and more particularly to those having a reciprocating motion of the blade, by means of which the shaving operation may be performed more quickly, easily and effectively than with razors of the forms of construction now. in use.

A further object of the invention is to provide a removable blade which is easily.

and quickly adjusted in position for use, which may be removed and replaced when desired.

Further objects and advantages of my improved construction will be apparent to those skilled in the art and in the accompanying drawings I have illustrated what I now consider the preferred form of my invention which consists in the construction and novel combination and arrangement of parts hereinafter described, it being understood that various changes in the form pro-- portion, size and minor details of construc- 1 tion within the scope of the claims may be resorted to without departing from the spirit or of sacrificing any of the advantages of the invention. ings:--

Figure 1 is a side elevation of my invention;

- Fig. 2 is a top plan view of the'razor head partly "broken away; i

Fig. 3 is a plan view of the razorblade;

Fig. 4 is a detail of the roller detached from the frame;

Fig. 5 is an enlarged detailed side elevation of the razor hea'd, partly in section, illustrating the adjusting mechanism.

' Referring to the drawings 6 represents the handle of the razor, which may. be or may not be knurled as shown. Mounted upon this handle 6, or if desired formed inte grally therewith, is a supporting member 7 which is arranged upon an angle to the handle, as shown in .Figs. 1 and 5. Extending transversely of one edge of'this frame and preferably formed integrally therewith Specification of Letters Patent.

are a plurality of guard teeth 8, above which the razor bladeis supported.

' The upper face of the supporting member 'q' is provided with a recess 9 extending parallel with which is a plurality of ribs 10 for a purpose hereinafter described.

number to the ribs 10. p v

A roller 15 is positioned in the recess 9' and 14 whichmay be manipulated for adjustment by 'means of the thumb nut 16 which extends beyond the end of the supporting member 9 and the frame 11. This roller is provided with longitudinally extending ribs 17 which engage grooves formed between the ribs '10 and 14.

Mounted in suitable bearings formed in the frame member 11 is a roller 18, the pe ripheral face of which has longitudinally extending grooves 19 which grooves pro vide a. roughened surface forming-better contact with the surface of the face when the razor is not used. This roller is also provided with a plurality of circumferentially extending grooves 20. The ends 21, 22 of the roller present cam surfaces as shown more clearly in Figs. 2 and 4. Corresponding cam surfaces are provided in some of the grooves 20 formed in the pe ri heral face of the roller.

ivotally mounted upon the end of the 5 frame 11 is a retainingmember 23. Th s member 23 is preferably formed of two sides extending at right angles to each other as shown in Figs. 1 and 5. The top portion of this retaining member is provided with the ribs 24 extending lengthwise thereof.

25 is a razor blade designed to be used with this construction, which is rectangular.

in shape and is provided with an elongated opening through the body thereof as shown in.Fig. 3.

27 is the shaving edge of the blade which rests'upon the guard teeth 8 when in position for use, the opposite edgeof the blade being provided with longitudinally. extending grooves 28 which arevengaged by the ribs 24; formed on the underside of the retaining member 23.

Formed integrally with the blade 25 and I projecting into the recess 26'are a plurality of fingers 29, which, when the blade is in operative position project into the grooves, 20, shown more clearly in Fig. 2.

Attached to each end of the frame member 11 is a'clip 30 which is bent over the edge of the blade 25 to retain the same in position. The cam surfaces 21-22 of the roller 18 contact with the inner edges of the opening 26 of the razor blade 25.

In operation the surface of the roller 18 contacts with the face and in moving the same, a reciprocating movement is transmitted to the blade 25 through the fingers 29 which are positioned within the circumferential grooves 20. The cutting edge 27 of the blade may be adjusted by turning the roller 16 which movesthe frame 11 on the supporting member 9 which will adjust the blade with respect to :the' guardfingers 8 in any relative position required. hen it is desired to remove the 'razor blade 25, the clips 30 are turned out of contact with the blade, and the retaining member 23 raised out of engagement with the blade when it can be removed from its place.

I claim 1. In a safety razor, the combination of a supporting member rigidly mountedupon the handle of the razor, an adjustable frame carried by said supporting member,

specification.

angle thereto, said member having guardteeth arranged on one edge thereof, an adjustable frame carried by said supporting member, a roller having circumferential grooves therein, a blade having an elongated opening therethrough, means on said frame for engaging said blade and ma1n-" taining it in position, means for adjusting. said blade with respect to the aforesaid guard teeth, and means for imparting a reciprocating motion to said blade.

3. In a sa-fety razor, the combination of a supporting member, a frame movably mounted-thereon, a retaining member pivotally mounted in said frame. a razor blade having one edge thereof engaged by the. aforesaid retaining frame, said blade having an opening therethrough, a roller mounted in the aforesaid frame and extending into said opening and means on said roller for imparting a reciprocating motion to the blade.

v In testimony whereof I have signed this JOHN L. KING.
