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 arms12, the ends 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 toat 13 l ward 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 efiiciency as well as the comfort.

- I claim; a A safety razor comprising a frame, a handle associated therewith, a knurled roller revoluble in said frame and having a cam groove,.a pairof 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.
