RAZOR Filed April so, 1954 Patented Apr. 7, 1936 UNITED STATES RAZOR Ernest T. Fry, Baltimore, Md., assignor, by mesne assignments, to Jacob M. Moses, Baltimore, Md.

Application April 30, 1934, Serial No. 723,264 2 Claims. (Ol. 30-53) This invention relates to safety razors of that type in which the handlev is in the plane of the blade so that the operation of shaving is performed in the same manner as with the old style straight razor.

One of the objects of the invention is to provide a two-edged blade and a frame or holder therefor in which the blade is frictionally held in a slot formed between front and back face member either integral with or secured to a handie, the blade being withdrawable from the frame or holder without loosening or detaching any mechanical part of the holder.

Another object of the invention is the provision of a two-edged blade having a spring rib extending longitudinally between the edges so that the blade in contacting a stili beard may yield microscopically preventing pulling of the beard and insuring a smoother cut.

A further object of the invention is the provision of a holder for receiving a two-edged blade with the spring rib as described, the holder having a flat slot for receiving the blade and a tubular channel intersecting one side of said slot affording a seat for the spring rib, said channel forming a nue in connection with the flat slot, so that when the frame or holder is suspended for drying, air may circulate through said iiue and said slot, thoroughly drying those parts of the holder to which a towel is not accessible.

Another object of the invention is the provision of a razor of the class described in which the front and back face members between which the blade is supported are of similar external contour whereby all four sides of the blade edges may be presented to the face in shaving.

Other objects of the invention will appear Vas the following description of preferred and practical embodiments thereof proceed.

In the drawing which accompanies and forms a part of the following specification and throughout the several figures of which the same characters of reference have been employed to denote identical parts:

Figure 1 is a plan view of the safety razor part of the handle being broken away and showing the blade inserted;

Figure 2 is a longitudinal cross section;

Figure 3 is an end elevation;

Figure 4 is a perspective view oi the blade;

Figure 5 is a plan view of a slightly modified form of the invention, part being omitted; and

Figure 6 is a cross section taken along the line 6--6 of Figure 5.

Referring nowV in detail to the several gures the numeral l represents in general the frame or holder which has a handle portion 2 and front and back face portions 3 and 4 here shown, but not necessarily, as being formed integral with the handle and spaced apart so as to define a 5 narrow planar slot 5 for receiving the blade 6. Said blade, as will be observed from Figures 3 and 4, has a longitudinal arcuate rib 1. This rib is received in a substantially semi-cylindrical channel 8 formed in one of the face pieces and 10 opening into the slot 5. One or both of the face pieces is formed with an indentation 9 at the end exposing a portion of the blade so that the latter can be grasped between the thumb and nger and withdrawn. It is held in place solely by the fric-tional pressure of the face pieces, said face pieces being preferably sufliciently yielding so that at the time of shaving, the pressure of the razor against the face constricts the slot 5 somewhat near its outer end, increasing the frictional pressure upon the razor. This, however, is not essential to the invention and in fact it is preferred that the portions of the blade which flank the rib 'l be substantially free from pressure since the rib l makes the blade resilient so that when the edges engage the hair they may yield microscopically dampening the impact which causes pulling of the beard and insuring a smooth and comfortable cut. This resilient action would be materially thwarted if the front and back face pieces came together throughout their entire length with added pressure at the time of shaving.

The rib 'I also acts as a metallic reinforcement for the razor making it possible to construct the frame or holder of relatively elastic material such for example as Celluloid and of thin construction, without it being subject to excessive flexibility.

It is obvious that in a frame or holder of this style it is impossible to get a towel into the nar- 40 row slot 5 or the channel 8 for the purpose of drying the holder. This disadvantage is obviate-d however by the relatively large cross sectional area of the channel 8 which forms a flue communicatcating with atmosphere through the sides of the narrow channel 5 and also through the spaces l0 between the guard tongues Il. The frame or holder may be suspended upon a suitable hook or nail inserted through the aperture I2 in the handle. The air rising or falling as the case may be through the channel 8 will induce a circulation of air through the spaces and the sides of the slot 5, thoroughly drying the hidden surfaces before incipient corrosion can take place.

It will be noted in that form of the invention shown in Figures 1 to 3, inclusive, that both face members are externally alike, being similarly con- Vex, so that all four sides of the edges of the blade are equally available for shaving Without reversing the position of the blade. This has the advantage that a man may shave with or against the grain of the beard and on both sides of his face without changing the blade or altering his grip upon the handle.

In Figure 5, a slight change in the design of the razor is shown in which one only of the face members is convex, the other 4 being formed with extending guard tongues i3. Only two sides of the edges of this blade can be employed in contact with the face, but the construction has the advantage of greater safety in view of the extending tongues, a feature which cannot be incorporated in the iirst described form of the invention for obvious reasons.

While I have in the above description, disclosed what I believe to be preferred and practical forms of the invention, it is to be understood that the specific structure and arrangement of the parts as shown is by way of example and not to be construed as limiting the scope of the invention as claimed.

What I claim is:

1. A razor comprising in combination, a holder having front and back face portions separated by a narrow planar blade-retaining slot, one face portion having an arcuate longitudinal channel opening in said slot, and a two-edged blade receivable in said slot having an arcuate rib tting said channel for holding said blade against lateral displacement, both of said face portions being of similar external convex contour and having their marginal edges serrated adjacent the sides of said slot, forming guard tongues.

2. In a razor including a holder comprising a handle, and front and back face portions constituting longitudinal extensions of said handle separated by a narrow planar blade-receiving slot and one face portion having an arcuate longitudinal channel opening in said slot, a two-edged resilient blade bent up intermediate said edges to form a resilient concavo-convex rib receivable into said channel for holding said blade against lateral displacement, said rib imparting resilient yield to said blade when under shaving pressure.
