The upper side of said teeth is formed by the guard faees 132, end the rear wall of said wash pockets 10 is fer: ld by the Wash curve 13, intermediately tangent to the inner ends of the curves forming said guard faces 12. The interior configuration of these wash packets 10, is of essen iel practical importance in the performance of my razor, the same having been deveioped' by experience and being designed so uftferd the greatest practicable facili in Washing out the lather to free the under side of the razer 7 1 i edgeof Said shoulder heats: o the under side-of the beveled edge 3 iinpihgedly held on guard faces.

'Theblad'e 1-8 is impingedly clamped upon the plane. outer ,face 15 ofthe'blade head 7 by the clip cap'21, provided with integrally dependent, manually expandable spring clips 22 at either end thereof, which b their inward compression, the ends' of the blade head 7., I

Thei'clip-cap 21', as clearly shown in Figs. 3 and 7 '1s;somewhat less than half of the width'of the blade'18,'it-bei ng thus designed v half of the bladev shall be rigidly-clamped down, and the remaining front portion given resilient freedom of action. The attainment of this resiliency is completed bythe elastic action of the tension importance in the I lip 23in a co lip 23', whose grip bevel 24 facts as a knife e ged .retainer, resiliently holding the top edge of the base ofthebevel 17 of the blade the-blade in my safety razor the same-elasdihery lion-safety razors, and thereby 'con-. *toitsfclose adhesion'to the skin in i'shavi'ng. and eflic ency mremoving the hair. of the skinpresenting inequali' i yrazo'r, whi' hentirely differentiates-it from I anew may ofthe unconfined. blades of ortiefs, 0 surface.

The special action of my the action f ether, safety razors, is primarily due to said resiliencie'sof its parts combined I with thegpeculiar 'tensioningit gives to the skin being shaved, whieh is accomplished by cially formed upwardly to thelfront. edgejof said.

tween said guard faces and tension arch, presenting the hairs thereon at a sharp angle to the cutting edge 17 of the blade 18 which is thus adapted to smoothly pass over the skin and Shave it closer with safety than would be possible without such adhesive tensioning thereof. This resilient action of a free elasface 15 of a height equal to the thickness of the blade, has preferably on its front side a V.-point 28, see Figs. 4, toengage the V-aperture edge vof'the blade,

6 and 9, adapted 29 cut in the back as best shown in Fig, 6.

The manner in which the'clip-cap 21 1m-' pingedly holds down the blade by its spring clips 22 in locked engagement'with the blade head 7's shown in Fig. '7, and the elastic locking tendency of the spring clips .22 of the clip-cap 2 1 is evident from their unexpanded positions shown in the detail of the detached clip-cap 22 given by Fig. 8.

The operation of my invention lows: The, razor is assembled for use by layingthe blade 18 on the outer face of the so tic cutting edge of a razor blade upon an aufrom the action of the safety or non-safetyvtype of construcis as folblade'head 7 in alined engagement with the key-lugs 27. The clip-cap is then engaged with one side of the blade head ,7, snapped down-over the other side and the razor isready for use. To take the razor apartf r cleansing, I

clip-cap 21 and blade 18 removed and. the parts are, ready for "rinsing and drying.

The adjustment in closeness of shaving cut closeness. WVhen a closer shave is desired,

the handle is held with its lowerend away from the face; and when the closest shave obtainable is desired the blade isslightly either of the spring clips 22 1s manually expanded, the

pushed forward beneath the clip-cap on the blade head, and the handle held in its' nor-l mal vertical position for shaving.

I claim 1. In a safety razor, a blade supporting structure including a guard provided with comb teeth each having a convexly curved surface on the upper side thereof -a blade having a shaving edge projecting over and along the said teeth, and a clip cap member having the rearward portion adapted to en-' gage the said supporting structure to hold said blade in place and including a forward resilient portion engaging the forward portion of the blade and co-extensive therewith in length whereby the blade is allowed to fieX.

2. In a safety razor, a blade supporting structure including a guard provided with comb teeth each having a convexly curved surface on the upper side thereof, a blade having a shaving edge projecting over and along said teeth, and a clip cap member having a rearward portion substantially equal to one-half the width of said blade and engaging said blade and supporting structure to retain the former in position, said clip cap member including a forward resilient portion engaging the blade adja-.

cent the. edge thereof and extending the entire length of said edge whereby the blade is allowed to flex.
