ApplicmtionY med-November 21, 1922; Serial No. 602,378.
l 'My invention relates to safety razors .and
is particularly applicable to the class of safe- Aty razorsA comprisirlig a guard, a backing and a thin flexible bl e c amped between the 5 guard and the backing to retain the cutting edge of the-blade in shaving relation to the guard teeth, In the clam of razors describedA it hasbeen customary, so far as I am aware,
to provide the backing member I0 that project through holes in the blade'and into holes in the guard member, Wherebyi n DI'IeSPOndlng parts 1n the several views.
the blade and the backing are retained from'- rotation on the guard by the cooperation of.v
said pins with the guard andthe clamping 15 of the blade between the guard member and the backin member, sothat the blade-per# forms no notion in retaining any ofsa'id .parts with relation one toanother.
. The object of" my invention '1s to provide a safety razor whereinj with a guard membeiwto-retam theA blade 1n shaving relation. thereto and the blade, will also cooperate with abackin member to retain the latter in proper relation to the blade for shaving purposes, so that-:the position of the backin member with regardA to the guard mem er-is maintained by the blade and not by `the cooperation of said members together in the ,well -known manner I have .30 described above. y-
In carrying outmy invention I provide a guard member and a blade having cooperative means to retain the 'blade in shaving position n the guard, a backing member for the blade, means cooperative between the blade and the backing member whereby the blade retainsthe backing memberin operative relation to the blade vand the guard, and means to cause theguard memberandbaek- '.40 ing member to clamp the blade therebetween.
My invention also comiises novel'details of improvement that will Y more fully hereinafter set forth and then pointed out'in the Reference is had tothe accompanying drawings form-inge part hereof, where- Ing my invention; '4:3 ig. 2 isa similar view, the "backing member being removed; v Fig, 3 4is a planview of the guard mem- .ber' 'f Fig. 4 is-'a cross section on line4, 4 in with pins- @111g Lwhic thecuttlng edges of the blade may ablade will cooperate extend4 in an ordinary( way .for shaving.

Similar numerals of reference indicate The guard member is indicated at 1, vthe blade `is indicated at 2, and at 8 is a backing member, so organized that the blade may be clamped between said members` The uard member is shown of the varietyhavard teeth I? on 'opposite sides-along vAny suitable means may be rovidedfor causing the blade to be clampe between the guard `member and the backin `member. In the, example illustrated the ackin'g member 3ds provided with'a threaded projection l4 adapted topass through a centrally disposed hole inthe guard member toA receive the internalportion of a suitable handle t5 to clampl the parts together for shavin The blade is provided with a substantialy centrally disposed opening 2a vthrough which the projection 4 of the backingmember may pass when the blade is between the members 1 and 3. lIJIeretofore, so far as I am aware, the opening in the blade for the ,projection from the backing for clamping the parts together has been circular so that `reliance was had `upon spacedy pins projectxin from the backing to pass through spaced ho es -in the blade and i to holes 'in the guardmember to keep the b ade and backing in osition on the guard member. In accor ance with my invention I provide co-` operative means -bet-weenfthe blade'and the guard member to keep the blade from rotat- Fig. 5 is a longitudinal section on line in'g'o'n said member. For such purpose IQ -provide a projection 1b on-the blade side of tion to the blade and the guard snugly to receive the metal""at thesidesbfA opening 2a so that the blade will, by sald means -to receive the projection `1b of the guard member, for which purpose I have shown the backing member provided lwith an outwardly disposed depressed or recessed portion 3a which will receive the projection 1b while the side portions of the backing member bear upon the blade for clamping it against the gua-rdf member.
When the parts are to be assembled for use;l the blade may be placed upon the guard member so that the projection 1b of the latter will enter the opening 2 of the blade and thereby the blade is positioned in proper relation to the guard, and the backing member 3 will be applied upon the blade so that its projection 4 will pass through the4 blade and the guardmember and the projectionsl 6 willenter the openings or recesses 2b of l the blade, whereby the backing, by means' of the blade, is properly positioned upon theblade with respect' to its cutting edges and with respect to the guard teeth, whereupon the handle 5 will be screwed upon the projection 4, thefhandle engaging the guard member, Vto clamp the parts firmly together for shaving, (Fig. 5v). The projections or pins 6 do not cooperate with the guard b member to retain the backing member 3 with respect to the guard member, the guard member being shown shorter, where the projections 6 extend throughthe blade, than the distance between said projections in the direction of the length of the guard member, so that the latter does not interfere with the projections 6. The guard member 1 and backing member, 3'are shown curved 1n atransverse direction whereby a thin blade 2 may be clamped. therebetween in a curved shape to stifl'en the blade ina well known manner, although the guard member and backing member may have other shape if desired.
In accordance with my invention the blade is retained upon the guard member in the pro er position by means of the cooperation of t e projection 1b and the sides of opening 2a of the blade irrespective of the backing, sothat when the blade is placed upon the guard member said parts will be in Vof the projection,
proper ositipn to receive the projection 4 backing* without the inconvenience sometimes experienced ofhaving to manipu' late the blade to register its holes with spaced holesfof -the guard, as heretofore known, and when the backing is applied upon the blade it will immediatel be posi- .tioned and retained by reason of t e projections 5 entering the openings or recesses 2b in the blade, so that the parts are conveniently yretained to receive the handle for clamping the parts together, the blade performlng a new function in retaining the backing member'A with relation to the blade and to the teeth of the guard member.
Having now described my invention what Iclaim is:
1. A blade having 'a non-circular opening substantially centrally disposed to retain the blade in shaving relation to a guard member, said blade having means spaced from said opening to cooperate with a clamping member to retain the latter in shaving relation to the blade independent of the guard member.
