SAFETY RAZOR Filed NOV. 4, 1940 Patented July 11, 1944 UNITED SAFETY RAZOR Lewis H. Swann and Judson P. Bowen, Atlanta, Ga.

Application November 4, 1940, Serial No. 364,302

2 Claims.

This invention relates to safety razors and, among other objects, aims to provide a very simple, cheap, compact and efficient guard and blade assembly adapted to be manufactured and sold as a unit in competition with blades used in ordinary razors and to be used and discarded after the blade becomes dull. Another aim is to provide a composite guard and blade assembly of this type adapted to be used in conjunction with a simple handle which can be made of metal, wood or molded plastic material and sold in compact ackages at a price not greatly exceeding the price of the same number of ordinary blades. Still another aim is to provide a simple type of handle which can quickly be attached to and removed from a blade guard or sheath.

Other aims and advantages of the invention will appear in the specification, when considered in connection with the accompanying drawing, wherein:

Fig. 1 is a front elevation of a safety razor embodying the invention;

Fig. 2 is a fragmentary end elevation;

Fig. 3 is a fragmentary top plan View of the sheath and handle; and

Fig. 4 is a sectional View of the assembly shown in Fig. 3.

Referring particularly to the drawing, the embodiment of the invention shown in Figs, 1 to 4 includes a composite blade and sheath or guard assembly designed for use with a screw threaded handle. In this instance, the sheath is adapted to be made of thin sheet metal which is cut or stamped out and bent upon a single edged blade l8 in such manner that the blade is permanently secured in the guard or sheath. The sheath comprises an upper leaf II and a lower guard leaf I2 with a forwardly projecting lip or tooth section l3 having a groove l4 adjacent to the cutting edge of the blade to receive the shavings and lather and permit easy cleaning or washing. The width of the U-shaped sheath is such as to provide a seat for the back of the blade and hold it in proper place for eflicient shaving with the opposite leaves firmly gripping the sides of the blade to prevent displacement.

In Figs. 3 and 4, the sheath or guard is shown as having eliptical or non-circular openings 20 in both leaves registering with a similarly shaped hole in the blade and the handle has a noncircular xtension 2| with a groove 22 formed near its end leaving a head 23 on the end. The width of the groove is such as to receive both leaves and engage the non-circular hole by a slight turning movement to fasten the handle in the opening. In this instance, the handle may be made of hard wood or some molded plastic material, such as Bakelite. It is also contemplated that a smooth handle of any suitable material having a non-circular end portion may be frictionally engaged in the opening to hold it relatively rigid and it may be discarded after it becomes worn. Obviously, other forms of handles may be used and it is to be distinctly understood that the invention is not limited to the particular types herein shown and described.

From the foregoing description, it will be seen that the assembled blades and sheaths or guards may be manufactured at a very low cost. In fact, the commercial blades are approximately A" wide. Moreover, the sheet metal used need not be any thicker than ordinary commercial tin which can be cut, stamped, punched and otherwise worked without the use of expensive tools or machine dies. Such small safety razor assemblies willfill a great need, especially for travelers and business men. The blades and holders may be discarded after a single shave, thus eliminating any waste of time required for dismantling and re-assembling the ordinary safety razors. It is further contemplated that such safety razors may be used as an advertising medium and made available in hotels and resorts.

Obviously, the present invention is not restricted to the particular embodiment thereof herein shown and described.

What is claimed is:

1. In a safety razor of the class described, a single-edged blade; a U-shaped sheet metal sheath permanently assembled thereon, said blade having a central opening and the opposite leaves of the sheath having non-circular openings registering therewith; and a removable handle of softer material than the sheath having a substantially elliptical end portion adapted to be frictionally engaged in the openings in the leaves.

2. In a safety razor of the class described, a single-edged blade; a U-shaped sheet metal sheath permanently assembled thereon, said blade having a central opening and the opposite leaves of the sheath having non-circular openings registering therewith; and a removable handle of softer material than the sheath having a substantially elliptical end portion adapted to be inserted in the openings of the leaves, said elliptical portion constituting the bottom of a groove of varying depth, frictionally to engage the edges of said openings.
