G, W. KITTLE SAFETY RAZOR Jan. 27, 1931.

Filed NOV. 5, 1928 4f UUUUUJUUV face of a doivn-strike and it is desired that an up-stroke follow, a slight twist on the razor handle will place the opposite and upwardly inclined edge of the companion blade in a. position to accomplish the up-stroke,rso that the razor isnot acturallyrenioved from the surface and tiiiie is saved; Also,` in case a blade edge becomes ydull during use, a second, ythird and fourth blade edge may be brought into use if desired so as to have the razor render an efficient service with a minimum expenditure of timeand effort, since the blade need not be handled for replacement as in the case of other safety razors.

Oivingtothe coinpactnature ofthe assembly the lblades are practically half the Width of the conventional safety razor blade.v This feature has tivo advantages, na1nely,that the blades` may be secured more cheaply than standard razor blades because of less expense for materiahand because the blades are sufficiently narrow to be stored in the handle l() by makingthe saine hollow as indicated-at 10a and, providing the same With' a screw cap 10b forjhandyrremoval in `case blades are to be taken out or inserted. The'no'vel razor is thus a compact article in every Way, and may be 'carried like a fountain pen by thev average user, Vand especiallythose Who travel. For thisreason', it has been my preference toembody the article in the fountainpen form as shown in Figure' jl tofsecure compactness as Wellas to impart the attractivenessand pocket featurejof the fountain pen. n c v 4lhileI have illustrated and described the invention in the preferred form, it Will be evident that the same is capable of many minor .changes and refinementsand it is my intention to claim such changes and refinements as coming Within the spirit and scope of the appended claims.

VI claim: Y I Al. `A safety razor having a shank/,and opT posed blades applied laterally thereof, whereby to expose the side edges; of the blades, and means movable in the 'direction Vofthe length of said shank and having portions" adapted. to overlie theV outer surfaces ofthe blades to hold the longitudinalinter'- mediate aieafs'thereof contiguousivith said shank, the edgesof the blades projecting lateral-ly beyond the corresponding edges of sii'ch means Y Y 2. safety razor having a shank Yprovided ivith substantially convert:` surfaces at opposite sides,l blades applied laterally l i thereon-said bladesbeing curved to conform to thecurvature ofthe shank, ainember'movable lengthwise of said shank and having Vportions*"overlying the outer surfaces of the blades intermediate the cutting edgesv thereiof for Dressing the blades aga-inst the convexv l. b b

porfionsfof Vthe. shank, and said member and the blades'having inter-engaging portions ing means for the blades applicable to said shank from one end,"

4. A safety razor having a shank reduced whereby to provide blade supjvjorting` areas; blades adapted to be applied against such areas, and toothed guard ribs projected Afrom the shank between the edges of adjoining` blades, theflatter being curved in conformity to the shank and with their edges spaced from the `guard ribs, a vcombine-d confining and locking means for the blades applicable to said shank fromone end.` Y

5. A safety razorh'aving a longitudinally so in thickness in the direction of opposite sides split shank, Lbladesy applied laterally of the shank, a retainer for `the bladescharacterized byiianges and a Web, said Web received by the split in the shank.I Y

Y 6.. A safety razor having a longitudinally splitshanlnslotted blades applied laterally of the shank,za retainer for the blades char# acterized'by flanges and a Web, the 'Web receive'd'by the splitfin the shank and the i flanges holding the blades in contact With the' shank. f 7. A safety razor having a. longitudinally;

split shank, bifurcated blades applied later ally of the shank and with their divisions in registration with the sides of the shank split, and an H-section bar applied Witliitfsivveb in said `and A divisions, whereby to position the flanges of saidA H-sefc'tion rbar upon the blades to retain the saine to the shank.v

8. A safety razor having a partially-split shank, bifurcated blades applied laterally of the vshank and With their divisions inregis`- tration 'With the sides of the shank split, an Hesectionbar applied with its web in said split Vand divisions, whereby to position the flanges of said Hesection bar upon the blades to retainr the same to the shank, and con-v tinuationsof said iianges extending V'over the, outer surface portions of said blades to retain the saine against the entirev portion Vof the shank.. I

9. A safety razor having a partially-split shank, bifurcated blades applied laterally of the shank and vvith their divisions in registration With the sides of the shank split,- an l-,l-section bar applied -With lits vveb in said split and divisions, whereby to position the flanges of said H-section bar'upon the blades to retain the saine to the shank, and continuations of said ianges extending over the outer surface portions of said blades to retain the same against the entire portion of the shank, the split portion of the latter having a pointed extremity for entry between said outer surface portions.
