Definitions

  • Jfurther object is to provide. a safety razor, which 'ad'usts the cutting surface of the cutting bla e. or blades b contracting and expanding t e guard ory back vplaite'.
  • Another object of the invention is to provide a safety razor which is adaptedto ref ceive one or a plurality of cutting blades, and which may be readily knocked down for cleaning or packing.
  • a still further object is to provide a safety razor which may be disconnected from the handle, but at th same time will hold the blade or blades in heir places within the razor, thereby doing away with the necessity of assembling the different parts together when it is desired to use the razor the next time.

  • Fig. 18 is a sectional vView taken on the plane of line 18--18 of Fig. 17.
  • front plate 1 may be provided with'the integrally formed end ears 2, and. an interally formed threaded stud 3 or socket 4.
  • v n the inner tace of the front plate 1, and 95' longitudinally thereof, is formed a slot 5, for the reception of an adapter 6.
  • rl ⁇ hi ⁇ s adapter 6 is provided with a central opening 7, and a pairof studs 8 midway of the ends or s .pproxirnatel so.
  • the 'blade or lades 9 are slightly longer than the front plate l, and are provided Iwith oppositely disposed cutting edges l0.' SJlhe openings 11 inl said blades, are pro vided tor packing purposes.
  • the guard or back plate 12 is formed of resilient or springyV metal, and is made more thin at the inner portion 13, and'bowed to edectively cause the serrated side members 14 t0 advance or Yretract as tightened or loosened, thereby permitting a number of adjustments for shavuig.v
  • My improved razor consists of' a rigid the handle 15 is 11b the earsL 2, but are separated from the stud distance.
  • the handle member 15 isl provided with ⁇ a split socket 17, the outer end of which is threaded as at 18- to receive the nut 19, for
  • a threaded stud 20 or socket 21, as the case may be, is provided with an integral head or journal member 22, which is adapted to seat in and coperate with the split socket 17.
  • the threaded stud 20 or socket 21 engage the yguard-plate 12 and front plate 1, and hold them in position for instant use, so that when it is desired to pack the razor, it is not necessary to take the plates apart and ythe blades out, etc., but merely unloosen the nut 19 and Withdraw vthe head or journal member -22 from the socket 17. In this manner, ity will; be seen' that the razor may be quickly knocked down', and absolutely and entirely does away with the extra Work of assembling the various parts prior to the taking of each shave. If a rigid handle is' used, the socket 23 or stud 24 is employed.
  • the operation of my improved safety razor, with the adapter and single blade is as follows:
  • the front plate is placed in such a position that the adapter may be placed in the slot, and the single blade superimposed thereon.
  • the handle may be bent in any direc-y f tion or at any angle, due to the flexible connection, also that the handle may be detached Without disassembling the various arts.
  • An advantage of the adapter is that the razor may bel readil cleaned and dried around the stud-or soc et on the front plate,
  • An adapter for a safety razor comprising-a bar or plate, said bar having means at 4 its central portion to prevent longitudinal displacement, and a plurality of studs formed integrally therewith, positioned between thecenter and the opposite ends for engaging a different variety of blades.
  • a safety razor comprising a front plate, a resilient or flexible guard plate, a plurality of blades, and means connecting said front plate and said guard plate, whereby saidl guard plate may be contracted or expanded to slide the guard vrelative to the cutting edges of said blades.
  • a safety razor comprising a front plate, a longitudinally extending channel or slot therein, an adapter in said slot, a cutting blade engaging said adapter, and means comprising a handle connecting said front plate and guard plate,.whereby said guard plate may be contracted or expanded to vary the position of the cutting edge of said blade.
  • a safety razor comprising a front plate, a threaded stud integral with said plate, a longitudinally extending slot in said platf, an adapter seated in said slot, said adapte-r having a plurality of outwardly extending studs and means engaging the stud on said front plate, a blade engaging said adapter and seated on said front plate, a resilient guard plate, and means for contracting and expanding said guard plate to Var the position of the cutting edge of said bla e.
  • a safety razor comprising a front plate, ears formed at the opposite ends of said front plate, a resilient guard plate, and blades interposed between said front and guard plates and in Contact with said ears, and means for sliding the guard relative to the cutting edges of said blades.
  • a safety razor comprising a front plate, ears formed at the opposite ends of said plate, a resilient guard plate, blades interposed between said front and guard plates, and in Contact with said ears, and means connecting said plates, whereby7 said resilient guard plate may be contracted and expanded to slide the guard relative to the cutting edges of said blades.
  • a safety razor a front plate, an adapter having means to engage a razor blade, and means on said front plate to prevent longitudinal and angular displacement of said adapter.
  • a safety razor a front plate, an adapter having means to engage a razor blade, and meansextending through said adapter to prevent longitudinal movement of said adapter.
