To all whom it may concern:

Be it known that 1, JOHN vL. KING, a citizen of the United States, residing at New York, Kings county, New York, have inlowing, taken in connection with the drawingi, 1s a description.

y invention has for its object the production of a safety razor of the class known -as the reciprocating blade type, wherein the blade is given a shearing movement while in operation. 1

It is also an object of my invention to provide a razorof this kind which shall besim-- ple in its construction, comprise the fewest possible parts, and be eflicient in its operation, and to provide a simple form of blade adapted. to be. used particularly with this razor.

A further object of my invention is to i provide a razor of this class having a very 1 blade on the razor head being centralized removed,

simple form of construction for eifecting a reciprocation of the blade, but one which is very accurately adjusted to function in its operation. A further object of my invention is to provide an improved blade for use in a razor of this kind, one which has two-cutting edges whereby the usefulness of the blade is increased 100%, the means -for actuating said with respect to the blade and thus permitting either edge thereof to be adjusted in position for use in shaving.

These and other features of advantage will be apparent to those skilled in the art to which this invention pertains, and in the accompanying drawings T have illustrated what Tnow consider the preferred form of an embodiment of my invention, not wishing to be limited to the exact details there shown as T contemplate such changes as may be madewithin the scope of the accompanying claims, and in this drawing- Figures 1 and 2 respectively are a side and front elevation of my" razor, Fig. 3 is a top plan view, Fig. 4 is a view of the head or supporting frame with the rotating member and blade Fig. 5 is an enlarged sectional detail of the reciprocating mechanism,

Fig. 6 is a plan view of the blade.

Specification of Letters Patent. Pgmeynmd N i, 29 192 1 Application filed September 13, 1920'. Serial No. 409,871.

Referring to the drawings 7 represents the end of the handle, the other side, 10, being inclined at an angle to the fixedly secured portion of said frame extends downwardly and away from the handle of the razor.

This downwardly bent portion 10 of the frame is provided with a slot 11 in the center thereof for a purpose hereinafter de scribed. There is also provided in this inclined portion of the supporting'member an elongated opening 12,. and a plurality of small openings 13, which provide air passages between said frame and the blade to be supported thereon.

14.14 are uide posts extending upwardly from t e inclined portion of the frame member 8 and project into openings arranged in the blade to receive the same, and by means of which the blade is kept in perfect alinement during the reciprocating operation.

The free edge of the downwardly inclined portion 10 of the supporting member 8, is I serrated and is concave on the longitudinal edge thereof.

Bent upwardly from the attached ortion of the supportin frame 8, are the members 1515,% a cam roller 16. The peripheral face of this roller is roughened in any desired manner to facilitate the frictional engagement with the face when the device is in operation.

l'Z is a peripheral cam groove preferably arrangedat or near the center of the roller caringetween whlch 1s journaled 16, the cam surface thereon being perforated 4 frame. This oscillating member is curved to what i shall I at the end thereof as shown in Fig. 5 and carries a projection or head 22 which engages the opening 23, in the center; of the blade 24.

The blade 24 is provided with slots or elongated openings 25 arranged in longitudinal alinement with the central opening 23.

The guide posts,1414 extend into this opening 25 and serve to keep the blade 24 in the members 28 have turned on the frames which serve tohold said retaining member in elevated position, when the blade may be removed from the supporting frame, and a new one placed thereon. In Fig. 5 I have shown a plan-view of the blade 24 from which it will be seen that I have provided a blade having two cutting edges 29-30 with openings 25-25 and 23 arranged in longitudinal alinement with each other so that the blade may be placedin operative position upon the retaining projections on the supporting frame with either edgs in shaving position.

hen in operation the roller 16 contacts with the face being shaved and is thereby rotated. The rotation of said roller through the cam surface in the groove 17 actuates the oscillating member 19, which is in direct contact with the blade 24 through the center opening 23 and transmits thereto a reciproeating or shearing motion to said blade, which makes the process of shaving much more easily and quickly accomplished than with a blade having only a scraping action.

1. In a safety razor, the combination of a supporting member, a blade movably mounted thereon, a cam roller mounted in bearings formed in said supporting member,

an oscillating member pivotally secured at one end thereof to the rear edge of the supporting member, a projection on said oscillating member engaging the cam roller, the free end of said oscillating member extending downwardly through an opening in the supporting member, a projecting head on the free end of said oscillating member engaging porting frame, said inclined portion of the supporting frame having openings therethrough between said frame and blade to provide an air space, an oscillating element pivotally attached to the rear edge of said supporting member and extending downwardly through an opening in the supporting frame, an upwardly projecting head on the end of said oscillating element engaging said blade through an opening in the supporting frame and having engagement with the blade, and means for actuating said oscillating element and blade.

3. In a safetyrazor, the combination of a supporting member fixedly secured to the end of the razor handle and having a portion thereof bent at an angle to the handle, a cam roller and a blade movably mounted on saidmember, guide posts rising from said inclined portion and extending through openings formed in the blade, an oscillating member having one end thereof movably at-.

tached to the rear edge of the supporting member, a pro ection on said member extending into the cam on said roller, the free end of the oscillating member extending downwardly through an opening in the supporting member, and an upwardly extending projection on said oscillating member registering with an opening in the aforesaid blade whereby motion is transmitted thereto.

4. In a safety razor, the combination of a supporting member, fixedly secured to the end of the razor handle and having a portion thereof bent at an angle to the handle, a cam roller and a blade movably mounted on said supporting member. an oscillating member pivotally mounted atone end thereof to the rear edge of the supporting member, means carried by sald oscillating member having operativeengagement with the cam roller, the oppositeend of said oscillating member extending downwardly through an opening in the supporting member, a projection thereon having engagement through an opening in the center of the blade, whereby an oscillating motion is transmitted to the blade when the cam roller is actuated.

In testimony whereof I have signed this specification.

JOHN L. KING.
