RAZOR WITH SHAVING ANGLE ADJUSTING MEANS ROTATABLE ON A LATERAL AXIS Original Filed Sept. 15, 1961 42M A/VZZAM ATTORNEY United States Patent 3,224,090 RAZOR WITH SHAVING ANGLE ADJUSTING MEANS ROTATABLE ON A LATERAL AXIS James B. Kruger and Robert L. Bordeau, Staunton, Va., assignors to Philip Morris Incorporated, New York, N.Y., a corporation of Virginia Original application Sept. 15, 1961, er. No. 138,485, now Patent No. 3,111,756, dated Nov. 26, 1963. Divided and this application Aug. 28, 1963, Ser. No. 305,136 3 Claims. (Cl. 3063) This application is a division of our copending application Serial No. 138,485, filed September 15, 1961 which has matured into Patent No. 3,111,756 granted November 26, 1963.
This invention relates to safety razors, and more particularly those wherein a new blade is fed longitudinally into the head of the razor from an injector magazine; and has for its primary object the provision of a simple and highly effective razor construction which embodies means for adjusting the shaving angle of the blade.
Among the other objects of the invention in various of its aspects are the provision of an injector razor wherein the elements cooperate with particular certainty and effectiveness, under various conditions of operation, wherein one of certain improved types of adjusting means is provided, wherein a blade may be inserted and held in position with ease, certainty, and effectiveness regardless of the position of adjustment, and wherein there is provided a razor which will effectively perform the purpose for which it is intended. T 0 these ends the invention contemplates the provision in a razor of a member (more specifically a cap) having blade stops, a guard-carrying member (more specifically, a blade clamping member underlying the cap), arms on which the members are respectively supported and which are normally urged one toward the other and which have on one of them a shaft rotatable on a lateral axis and carrying on the ends thereof cam means having outward cam surfaces bearing against facing surfaces on the other to move the arms away from each other to vary the relative position of the blade stops and the guard to vary the shaving angle of a blade positioned by the blade stops.
The invention accordingly comprises the features of construction, combinations of elements, and arrangement of parts, which will be exemplified in the constructions hereinafter set forth and the scope of the application of which will be indicated in the claims.
For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings, in which;
FIG. 1 is a side view of the upper portion of a razor embodying the present invention in one extremity of adjustment;
FIG. 2 is a front view thereof partly broken away; and
FIG. 3 is a side view on an enlarged scale with certain parts broken away and others in section, and showing an intermediate position of adjustment.
The form of razor particularly exemplified in FIGS. 1-3 comprises two members (a cap and an underlying blade clamp 12c) adapted to receive a (rigid single-edge) injector blade 15c therebetween, the blade clamp 12c serving, in the present instance, to assure that the blade is held against the underside of the cap. The cap is carried on a supporting arm 15xc and both are part of a stainless steel frame member 16c, and the cap is formed at its forward ends with forwardly-extending members 17 carrying blade stops 18. The rear (dull) 3,224,096 Patented Dec. 21, 1965 edge of the blade is normally engaged by, and the blade thrust against the blade stops by, a tab 19 extending upwardly and forwardly from the central forward portion 21 of a laterally extending forwardly-bowed portion of a blade-spring 23c, one arm of which being welded to the frame member 160 toward the far side of the razor (FIG. 1); and the other arm being adapted to be contacted by the key of an injector magazine entering from the near side of the razor, the spring 23c being flattened and displaced by an injector key guided by flanges 1420 and 1430 integral with. the frame 160; and the adjustment of a resilient arm 35c (and the clamp 12c and a guard 62c therewith) is effected by a wheel-and-cam arrangement. The arm 15x0 of the frame 16c and the arm 350 are formed respectively with central openings 145 and 146 to receive a rotary operating member in the form of a wheel 148 having manually-engageable V-grooves 149 in the outer surface of its rim and fixed on a shaft 150 seated at 151 and 152 respectively in semi-cyl ndrical bearings in the frame 16c for rotation on a lateral axis (by a lateral axis is meant, as employed herein and in the appended claims, an axis extending widthwise of the razor, e.g., parallel to the length of the guard and to the plane of the blade clamp, as contrasted with the axis of the member 30 of Patent 3,095,645 which is normal to the width of the razor), and held seated therein by the resiliency of arm 35c, and carrying on its ends cam segments having outward cam surfaces 154 and 155 adapted to bear on a facing rearward surface 156 of the arm 35c to cam the latter forwardly as shown in FIG. 3. The frame 160 is cut out at 159 and 160 to provide recesses for the reception of the cam segments and stops 161 and 162 limiting the movement thereof. In Oldf to normally hold the wheel 148 in an adjusted position, there is provided a spring 165 disposed in a recess 166 and formed with a bend 167 adapted to spring into whatever V-groove is alined therewith. One end of the spring is divided to provide end portions 168 and 169 which are welded to the frame 16c, and the other end 170 thereof is bent rearwardly to lie and bear against the bottom well of the recess 166.
Since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
We claim:
1. A razor comprising a cap having blade stops thereon, an arm extending downwardly from said cap, a blade clamping member underlying said cap, a rearwardlyurged forwardly-movable arm extending downwardly from said blade clamping member forwardly of the aforesaid arm, a guard fixed to said blade clamping member, a shaft carried on one of said arms for rotation on a lateral axis, a manually rotatable operating member fixed to a central portion of said shaft for rotating the same, and cam means mounted on the ends of the shaft and providing outward cam surfaces bearing against facing surfaces on the other of said arms to move said rearwardly-urged arm forwardly to vary the relative position of said cap and said guard to vary the shaving angle of a blade positioned by said blade stops.
2. A razor as in claim 1 wherein said operating member is formed with an outer laterally-grooved operating surface.
3. A razor comprising a member having blade stops thereon, a guard-carrying member, arms on which said members are respectively supported and Which are normally urged one toward the other, and a shaft carried on one of said arms for rotation on a lateral axis and carrying on the ends thereof cam means providing outward cam surfaces bearing against facing surfaces on the other of said arms to move said arms away from each other to vary the relative position of the blade stops and the guard to vary the shaving angle of a blade positioned by said blade stops, and manually operable means on said shaft for rotating the same.
