Man ch 4, 1952 O. H. CROWELL SAFETY RAZOR Filed Dec. 30, 1946 I VENTOR. UJc'arJrf. ran/e ZZ.

Patented Mar. 4, 1952 UNITED STATES PATENT OFFICE 3 Claims.

My present invention relates to an improved safety razor of the type comprising a resilient split tubular blade holder and in which the backed blade may be inserted and retained, together with a handle detachably secured to the blade holder.

The present invention is an improvement over the structure set forth and claimed in Patent No. 2,382,296 and embodies a removable blade in lieu of the integral blade of that patent.

In the accompanying drawings, I have illustrated one complete example of the physical embodiment of my invention according to the best mode I have thus far devised, but it will be understood that various changes and alterations may be made in the exemplified structure within the scope of the appended claims.

In the drawings:

Figure 1 is a perspective view of the razor of my invention;

Figure 2 is a perspective view of the blade;

Figure 3 is a side elevational view of the razor;

Figure 4 is a sectional view at line 44 of Figure 1.

- Referring now to the drawings, I have illustrated the present embodiment of my invention as comprising the spring metal blade holder or head In of cylindrical shape, which is longitudinally split at H to provide overlapping edges l2 and I 3 respectively, the edge I 2 being flattened at M and the edge thereof is beveled at 15, and intermediate of the flattened portion I4 and edge I 5, the end 12 is crimped at 16 to form a guard extending the full length of the holder [0. The inner end is crimped at ll and curved in at H! to form a longitudinal rib, and is then bent inwardly to form the flange IQ for a purpose to be later described.

The blade 20 beveled to a cutting edge at 2| has a U-shaped back 22 and the recess 23 receives the depression 24 in the holder when the blade is slid between the overlapping ends of the split tube, so that the back 22 engages the flange IE to properly position the blade 2!].

Opposed notches 25 in the ends of the cylindrical receive the spring wire or rod frame 26 forming a handle.

The back of the blade will rest against the fiattened portion IA of the outer overlapping edge I2 and will be pressed thereagainst by the rib IS. The edge I2 is provided with a longitudinal opening 21 through which soap and hair is discharged as the razor is drawn over the face, since the upper edge of the opening 21 is just above the cutting edge 2! of the razor 20 on the inner side thereof. The lower edge of the opening 21 functions as a guard to protect the shaver during the shaving operation, since it is in alinement with the crimped portions I! in the ends of the holder Ill.

The crimped portion [7, of the edge [2, provides edge guards for the outer edges of the razor to prevent cutting of the shavers face, and the guard I6, together with portion l1, provides guards for properly positioning the razor while shaving.

As described, the blade will be securely and detachably retained in the holder against the pressure applied to the cutting edge when in shaving position, and the flat surface of the back against the flat portion of the holder will prevent movement of the blade when in use.

It is to be understood that changes in the details of construction, arrangement and combination of parts may be resorted to, provided they fall within the spirit of the invention and the scope of the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure byLetters Patent is:

1. A safety razor comprising a split cylindrical head having a thin wall with the edges of the wall in overlapping relation and with the under edge having an outwardly extended flange on the end thereof, said under edge formed to provide a blade holding socket adjacent the flange said under edge having an outwardly extended longitudinally disposed rib spaced from the blade holding socket and extended to engage the under surface of a blade in the socket and also having a longitudinally disposed recess in the outer surface positioned to provide clearance below the cutting edge of a blade positioned in the socket, the outer overlapping edge of said cylinder being crimped inwardly to provide a blade holding guard, and a handle positioned perpendicular to the axis of the cylinder removably mounted on the ends of the cylinder.

2. In a safety razor, the combination which comprises a split cylindrical head having a thin wall with edges of the wall in overlapping relation and with the under edge having an outwardly extended flange at the end thereof, said under edge formed to provide a blade holding socket adjacent the flange said under edge having an outwardly extended longitudinally disposed rib spaced from the blade holding socket and extended to engage the under surface of a blade in the socket and also having a longitudinally disposed recess in the outer surface positioned to provide 3 clearance below the cutting edge of a blade positioned in the socket, the outer overlapping edge of the cylinder providing an outer wall of the blade holding socket and formed with the edge thereof crimped inwardly to provide a blade holding guard, said cylinder having notches transversely positioned across the ends thereof, and a centrally disposed handle removably mounted in the notches in the ends of the cylinder, and the split of the cylinder being in a plane parallel to the plane in which the axis of the handle is located.

3. In a safety razor, the combination which comprises a split cylindrical head having a thin wall with edges of the wall in overlapping relation and with the under edge having an outwardly extended flange at the end thereof, said under edge formed to provide a blade holding socket adjacent the flange said under edge having an outwardly extended longitudinally disposed rib spaced from the blade holding socket and extended to engage the under surface of a blade in the socket and also having a longitudinally disposed recess in the outer surface positioned to provide clearance below the cutting edge of a blade positioned in the socket, the outer overlapping edge of the cylinder providing an outer Wall of the blade holding socket and formed with the edge thereof crimped inwardly to provide a blade holding guard, said cylinder having notches transversely positioned across the ends thereof, and a spring wire handle with outwardly extended ends positioned in the notches of the cylinder with the handle positioned midway of the length of the cylinder and extended in a plane extending through the notches, said handle having inwardly extended projections on the end thereof and with the sides extended inwardly providing positioning means of the head in relation to the end of the handle, and the split of the cylinder being in a plane parallel to the plane in which the axis of the handle is located.
