Charles Richard Burke, of Chicago, Illinois. Safety-Razor.
1,249,021. Specification of Letters Patent. Patented Dec. 4, 1917.
Application filed March 16, 1917. Serial No. 155,254

To all whom it may concern:

Be it known that I, Charles R. Burke, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Safety-Razor, of which the following is a full, clear, and exact description.

My invention relates to safety razors of the reciprocating type. The object thereof is to provide a simple, inexpensive and efficient razor which is characterized by the provision of a top or cover plate which relieves pressure on the reciprocating blade when the razor is in use and also serves as an additional guide for the razor.

I attain the above and other objects of my invention by the structure conventionally disclosed in the accompanying drawings, wherein similar characters of reference indicate corresponding parts in all the views.

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

Fig. 2 is a vertical cross section;

Fig. 3 is a top plan view, a portion of the cover plate being broken out and the blade removed to show the details of construction;

Fig. 4 is a perspective view of the blade carrier. 7

Referring to the drawings, 5 is the main frame, which is provided with a suitable handle 6 extending from the rear part of the frame. A roller 7 is revolubly mounted in the front of the frame. The roller is knurled and provided with a cam groove 8 substantially midway between the ends thereof.

A blade carrier 9 is mounted to slide longitudinally of the roller in the frame on parallelly-spaced rods 10. A pin 11 secured to the under side of the carrier engages the groove 8 of the roller; consequently the rotation of the roller imparts a reciprocating movement to the carrier. The carrier 9 has lateral, oppositely-directed arms 12, the ends of which arms are folded as shown at 13 to form seats for a blade 14.

A plate 15 straddles the frame 5 and constitutes a top or cover for the blade. It is secured to the frame by the rods 10 which serve as a guide for the blade carrier. To facilitate the engagement of the blade with the carrier when a blade is exchanged, apertures 16 are formed in the plate 15 which register with the seats 13 in the carrier. The front edge of said plate is depressed toward the blade so as to form an additional guide. This plate comes in contact with the surface to be shaved and prevents interference between the major part of the blade surface and the surface to be shaved, and, therefore, increases the efficiency as well as the comfort.

I claim:

A safety razor comprising a frame, a handle associated therewith, a knurled roller revoluble in said frame and having a cam groove, a pair of parallelly-shaped bars in the frame disposed parallel to the roller, a blade carrier slidably mounted on said bars with means for engaging the groove of the roller, lateral arms on said carrier for receiving a blade in proper relation with the roller, and a cover plate secured to the frame by said rods to rest over the blade on the carrier, said plate having the edge nearest to the roller depressed toward the plate to form an additional guide for same.

Charles Richard Burke.
