4 SAFETY RAZOR Filed March 21, 1930 Patented Dec. 16, 1930 ERIC W. ERICSSON, F BROOKLYN, NEW YORK SAFETY ZOE application met naar a1, wat. serial no. estere. y

This invention relates to safety razors and particularly to devices of this class employing double edged blades and a holder for supporting such blades; and the object of the [y invention is to provide an improved type kof blade holder and especially an improved guard plate for holders of this class whereby a :tree cutting edge is formed on each edge of 'the blade when mounted in the holder from 1o points adjacent the ends or corners of the lade throughout the full length of said edges; a further object being to support a blade in connection with the holder in the manner set forth and to provide a plurality .t6 of transverse passages between the guard plate and blade and eXtendin from one 'cutting edge to the other and into which the lather is free 'to pass in the operation or use of the razor, and further to the provision of supporting ribs arranged intermediate said passages or grooves upon which the blade is supported; al further object being to arrange the transverse grooves of the guard plate in alinernent with the projecting guard lingers disposed at opposite side edges of the guard plate so as to arrange the upper surfaces of said iingersin spaced relation with res ect to the cutting edges of the blade; and wit these and other objects in View, the linvention consists in a razor of the class and for the purpose speciiied which is simple in construction, elhcient in use and which is constructed as hereinafter described and claimed..

1 to l inclusive. However, with the guard plate 16 shown in Fig. 5 of the drawing, the, t@

pins l5 are not employed.

rlhe present inventlon relates rimarly to the construction of the guard pate l2-l6. The opposite side edges of the plate l2, note Fig. 4, are recessed as seen at 17 to form a et plurality of longitudinally spaced ngers 18, the outer and lower surfaces ofwlnch are rounded as seen at 19, note Fig. 2. The upper face oi? the plate'12 is also provided with a plurality of transverse recesses 20 arranged te in alinernent with all of the fingers i8 excepting the outer lin ers at each end ol the plate. designated by t e reference character 18a. These recesses form correspondingly spaced ribs 2l normally in the same arc-shaped path l5 as 'the upper surfaces of the ends 22 ord the guard plate so thatin supporting and clamping the blade 13 upon the guard plate, said plate rests upon the ends 22 and the ribs 2l, thus forming of the recesses 20 transverse chan- 3U nels extending from one side of the plate l2 to the other side thereof or in other words troni one cutting edge of the blade 13 to the other, and further operating to support the cutting edges 13a of said' `blade intermediate the ends 22 above and in spaced relation from the upf per surfaces of the ngers ld, thus providing an unobstructed passage beneath the cutting edges ot the blade into which Vthe lather is ire-e to pass and extend into the channels .termed gli' by the recesses 20. At the same time, it will be apparent that the cutting edges are supported by the side edges of the cap il and the end pon tions of the ribs 2l.. i

lt will also be apparent that the corner g or @il tions oi the cutting edges el the blade wi l be supported snugly upon the corners 18e of the guard plate l2, thus preventing the possibility et cutting or injury to the face withta shavingstrekekbut Lpernnitting the use et the corner portions in shaving as in other razors f* to. flow transversely through the razor from side edges of said plate and a plurality of lrecesses arranged transversely of the p late and in alinement with each of said projectone side edge to the other, the channels serving to break up and loosen the lather from the surfaces of the several parts of the razor and 'the ends of the ribs 21 serving to deflect the waterdownwardly through the spaces between the fingers 18 to thoroughly clean the razor.

The guard plate16 shown in Fig. 5 of the drawing differs from the plate 12 simply in the provision ofarc-shaped channels 23 at opposite sides of the central portion of said plate, the channels opening outwardly through the upper convex surface of the plate and being substituted for the side apertures through which the guide pins 15 pass. This type of plate is designed for use in conjunction with other types of blades. However, the upper surface of the plate 16 has the trans- 'verse recesses 20a. similar to the recesses 20 and arranged in alinement with the spaced fingers 24 at opposite sides of the plate and forms between the blade and said plate the channels above referred to andalso the free suspension of the cutting edges of the razor blade between the corners 16a of said plate.

The recesses 20a form on the upper face of the guard plate raised ribs. The end ribs being wider and longerthan the-intermediate ribs and the upper surfaces of the fingers 24 being continuous with the bottom surfaces of said recesses.

It will also be understood that my invention may be applied to other types and forms 'of razor blade holders and other changes in and modifications of the construction herein shown and described may be made Within the scope of the appended claims without departing fromthe spirit of my invention or sacrificing its advantages.
