INVENTOR eTosEfil-l Munos ATTORNEY Patented July 25, 1933 UNITED srarss misses Fi rce JOSEPH MUROS, OF NEW' YORK, N. Y., ASSIGNQB T0 GILLETTE RAZOR COMPANY, OF BQSTON, MASSACHUSETTS, A CORPORATION OF DELAWARE SAFETY RAZOR Application filed May 21, 1931. Serial No.,.538,990.
Safety razors of the class comprising blade clamping members, which include a guard member and a cap or blade backing member, are frequently provided with means to register the members in shaving relation, the same means also registering the blade in shaving position between saidymembers, the
blade customarily being provided with one ormore apertures that fit the said means for registering or locating the blade in shaving position. i
' The object of my invention is to provide a safety razor having blade clamping members, said members having cooperative means to register them in shaving position, one of said members having additional means to locate or register a bladein shaving position between the members, .which blade does not have an aperture to lit the means that register the clamping members, which blade would otherwise be loose between said members.
In carrying out my invention I provide blade clamping members and means to clamp said members against a blade, one of said members having projections adapted to cooperate with the other member to register said members in shaving position, said projections being adapted to enter a corresponding aperture or apertures in a blade to register said blade in shaving relation to said members, one of said members also having means to engage a blade that is provided with an aperture not adapted to fit said pro tion between the members.
My invention also comprises novel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims.
Reference is to be had to the accompanying drawing, wherein Fig. 1 is an edge view of a safetyrazor embodying my invention;
Fig. 2 is a section on line 2, 2, in Fig. 1; Fig. 3 is a section on line 3,3, in Fig. 2; r Fig. 4 is a partly broken plan View oi": Fig. 1, and
Fig. 5 is an inverted plan view of the cap member.
" Similar numerals indicate corresponding parts in the several views.
My improved safety razor comprises a blade clamping member including a' guard member 1 and a cap or blade backing member 2. At 3 is a handle shown provided with a threaded recess l at one end adapted to receive a threaded stem 5 projectingfrom the cap 2, which stem is adapted to pass through an opening 1a in the guard member, whereby when the parts are assembled, as in Fig. 2, the .members 1 and 2 will clamp a blade 6 V between them. The guard member 1 is shown provided with spaced projections. 7, and the cap or backing member 2 is provided, in its under surface, with recesses 8 that are adapted'to receive and fit. the projections 7, whereby the guard member and the cap will be located and retained in shaving relation when said members are clamped together against a blade. The projections 7 and the recesses 8 may have anyfidesired contour. Said projections are adapted to receive an appropriately shape-d opening or openings in a blade to locate said blade on the guard member and retain the blade in shaving position between the members 1 and 2.
In case a blade 6, having a large internal opening 6a, such as a longitudinal slot, that will not fit the projections 7 to register the blade in shaving position, be applied in the razor, it would not be retained in .shaving position with respect to the guard and the cap. I provide one of the clamping members with means independent of the projections 7 to engage the blade 6 to retain it in shaving-position between the members. 1 and 2. I have illustrated a cap or blade backing member 2 as provided at its ends with projections 9 that extend beyond the ends of the Q guard member, when the parts are assembled as in Fig. 2, which projections are adapted to being adapted to enter the recesses 6" when the parts are assembled, (Fig. 4). The projections 6 are shown located beyond the cutting edges at the ends of the blades.
hen the parts are to be assembled for shaving, the cap or blade backing member 2 may be placed in the inverted position shown in Fig. 5. he blade may be placed upon the cap with the projections 9 entering the recesses 6 shaving relation to the cap, and the guard member may be placed upon the blade, the projections 7 of the guard member passing through the relatively large opening 6a of the blade and entering the recesses 8 of the cap, whereby the guard and cap will'be retained'in shaving relation, and then the handle may be screwed on the stem 5 for clamping the members 1 and 2 against the blade. Since the projections 7 and the recesses 8 of the guard and cap members locate and retain said members in shaving relation but do not themselves retain the blade 6 in'shaving position, the latter will be retained in said position by the projections 9 without regard to the projections 7, since-without the projections 9 the blade 6, having the enlarged opening 60, would be liable to be inaccurately located between the clamping members.
Having now described my invention, what I claim is:
1. A safety razor comprising blade clamping members, means to clamp said members of the cap to locate the blade in.
against a blade, one of said members having projections and the other recesses accurately fitting said projections and locating the two members in shaving relation, one of said members having an independent set of projections to locate and hold in shaving position a blade that has a large internal opening affording clearance with respect to said firstnamed projections.
2. A safety razor comprising a guard havingprojectionsand a cap having recesses accurately fitting said projections for locating the cap and guard in shaving relation, said cap having also an independent set of proj ections to locate and hold in shaving position a blade that has a largeinternal-opening afiording clearancefor the projections of the guard. I
3. A safety razor comprising a guard having projections, a cap having cap-locating recesses accurately fitted to said projections for locating thecap and guard in shaving relation, means to clamp the cap and guard against an interposed blade, and a blade having a large internal openingor openings leav ing the projections ofthe guard free and clear within the periphery thereof and rojections at the opposite ends of the blade, the cap having projections at its ends to cooperate with the projections of the blade for registering and holding theblade in shaving position between the cap and the guard.
