Y., ASSIGNOR To GILLETTE SAEETY RAZOR COMPANY, OE BOSTON, MASSACHUSETTS, A COREORATION OE DELAWARE SAFETY i RAZOR Applieation mea may 1,3, 1931. serilfNb. 536,979.

An Object of my invention is to provide means, such-as an adapter, to be applied to a safety razor to locate a blade in shaving position thereon which otherwise would not fit properly in the razor, as distinguished from a proper blade made to fit the razor.

A furtherobject of my invention? is to pro# vide such-an adapter that will not only locate a blade in shaving position in the razor but may also Control the position of the blade cap or blade backing member of the razor with relation to the guard member thereof.

This feature of my inventionis particularly applicable in safety razors having blade clampingV members'in which the blade capl or backing member and the guard member vdo not have cooperative means for locating the cap in shaving `relation toA the blade, as in those razors in which the blade itself cooperates with the cap or backing member to locate the latter in shaving relation to the blade and the guard member does not. Serve for such purpose. Y

In carrying out my invention I provide a safety razor comprising blade clamping members and means to retain said members clamped against a blade, with an adapter provided with means to detachably Vconnect it with one of said members, such as' the guardV member, said.` adapter and the cap or blade backing member having cooperative means a blade to retain the latter in shaving relation to a blade between said members, said adapter also having means to cooperate with a blade to retain the latter in Vshaving, rela. tion to the guard member, although said blade may not have means cooperativey with the guard member itself for positioning the blade thereon. n i. My invention also comprises novel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims. n

The blade clamping members, as indicated7 include a guard member l and a cap or blade backing member 2 adapted to elampa blade 8 between them. Any suitable means may be provided for clamping the vmembers land 24 against the blade. Ir have illustratedrthelcap 2 as provided with a threaded stem 4 adapted to vpass through an opening l?) infthe guard 5 in the handle 6 `for detachably clamping the members against the blade. My improved adapter for blades is indicated at 7, and comprises a piece of suitable metal shaped to rest 'against' the guard member l, between the lattenand the cap 2, andprovided with an opening 7a shown in the form of a longi tudinally disposed Slot,

and wide enoughto allow projections lO of the guard member l to pass freely vthrough said opening 7a. I have shown Vthe adapter 7 as providjed with marginal portions 8 adapted to extend along and lengage theouter surfaces of the guard guard member 1 for positionv teeth la; of the ling the adapter on said member. The marginal portions 8 of the adapter may be'curved Y in such a way as to partially enclose or underlie the edges of the guard teeth to retain" the in the threaded recessv adapter on the guard Vmember from lateral therefrom,A the end portions of the adapter being shown open whereby the. latter may be slidY lengthwise along the inner or blade-engaging surface of The 'marginal portions 8 of the adapter are shown provided with longitudinal slots .9 that register with the guard teeth' whereby lather from shaving mayV pass :guard member and through said apertures to and between the guard teeth.

Blade clamping members of the character set forth are customarily provided with means to locate and retain a proper blade in shaving Arelation to such members. ,v v The clamping members 1 and 2 may be provided with any desired means for positioning the blade for shaving in conjunction with a propv er blade. I have illustrated the guard memjber as provided with projections-10, spaced apart on opposite side of a hole 1b inthe said projections being adapt- 4 guard member, ed to vfit and cooperate with a proper. blade,

made for the blade holder illustrated, for 'retaining said blade in shaving relation tothe guard teeth. Thev blade 3, as illustrated, is provided with an opening 3a, shown in the f form of a longitudinally disposed slot,which will not properly lit the projections 10 of the therefore wouldbe loose and not be retained in proper shaving posiion between ,the clamping members. My imy proved adapter is designed to ,locate the said blade 3 in proper shaving position between theV clamping members irrespective of the character of the opening 3a` of a blade that does not fit the projections 10. I have shown the adapter 7 as provided at ,its ends with outwardlyextending projections 11 that are adapted to cooperate with the ends of the blade to retainthe latter in shaving position with respect to the guard member. (By preference the yblade is shown provided with projecting means V3b at its ends that are located in spaced relation by means of recesses 3 at the ends of the blade. When the adapter is in position on the` guard member and the blade 3 is applied against the adapter, the projections 10 will not properly lit the blade in its opening 3a but the projections 3b of the blade will engagev the projections 1l of the adapter, and thereby the blade will be located in shaving relation to the guard teeth.

In the example illustrated, it will be assumed that the projections 10 of the guard Vmember do not fit against the cap or blade backingV member 2 so as tolocate the latter in shaving relation to the blade. c As illustrated, the cap 2 is shown provided yin itsV under surface with recesses 12 that receive thev projections lOrloosely so as not to guide orcontrol theoperative position of the cap. The cap, however, is provided with'means tol cooperate with the adapter to locate and retain the cap in shaving relation to the blade.v I haveshown the cap as provided with projections 13 at its corners that extend towardthey adapter to engage the latter,

whereby'the adapter will position the cap with its longitudinal edges in proper shaving relation to the cutting edges of the blade.

I have shown'Y the adapter as provided at its endswith recesses 14 adapted to receive the projections 13 of the capforf'properlylocatadapter, (see Figs. 1 and 8).

ing and retaining the latter in position on the adapter. The blade is shown Vprovided with recesses 3 at its corners, that register with the recesses 14rof the adapter to permit the projections 13 of the cap to pass through the recesses 3. to enter the recesses 14 .of the Y The adapter, therefore, constitutes a means, when applied on the guard member, for retaining the cap in proper shaving position on ablade that otherwise would not lit properly in the blade holder. The'recesses .3 at the corners of the blade may be of suoli anv area as not to engage the 'lugs I3 ofthe cap although said recesses 3 may be of such dimensionsjas to engage said projections 13 and thereby the blade may position, or'assist in positioning, thecap in shaving position on theV blade. The guard member is shown provided with spaced recesses 15 which may extend all along the guard member in a longitudinal direction into which the proj ections13 of the cap may freely extend so as not to interfere'with the clamping of the blade and the adapter between the members land 2'.r

W'hen the blade holder is used withaprop'er blade to fit the projections 10 of the guard member,the projections-13 of the cap may engage such proper blade to 'causethe blade to position the cap thereon Vfor shavingin a well-known way. If, however, it is desired Y to use the blade Yholder described with a blade that does'no't properlyt tliesame, such as blade 3, the user will apply the adapteron the guard member and he maythen place the blade 3 on the adapterwhich Awillilocate the blade in shaving relation to the guard,andV

then by applying the cap upon the blade the i adapter will locate the cap in shaving .position on the blade,.so that when the partsfare clamped together, bythe stemv and the handie, the blade will be properly retained for shaving. l

Changes may be kmade in the details of construction set forth within the scope ofthe .appended claims withoutdeparting fromthe spirit of my invention.
