RAZOR Hale B. Straeten, Van Nuys, Calif.,.'asignor; tu Albertv Bontempi, Alhambra.'` Calif..

Application January 31, 19419,v Serial No. 23,781

- 1 Claim. 1 My invention relates generally to razors, and more particularly to a ladys safety razor which is adapted for shaving underr arms.

Due to the concave curved surface of the axilla,

it is diicult to shave thisv portion of the body` with an ordinary'straight-edged razor of conventional design. Special curved edge razors have been designed for this purpose, but have had numerous disadvantages. One such disadvantage arises from the fact that special. designs heretofore have necessitatedspecial. blades not always easily available for replacement.

Another disadvantage of previous construction is that often complex mechanisms involving a large number of separate parts, were required to hold the blade in place.

A major object of .my invention is to provide a razor for the purpose statedf which is adapted to use conventional double edged safety razor bladesv of the type. used in conventional mens razors.

It is another object or my invention to provide a razor of the class described which is easily and quickly assembled or dis-assembled, and which requires a minimum of working parts.

It is a still further object of my invention to provide a razor which is economical to manufacture, requiring only simple stampingoperations for its fabrication.

The foregoing and; other .objects and advano tages of my invention will become apparent from a consideration of the following detailed description thereof, such considerationbeing taken in connection with the attached drawings in which:

Figure 1 is a perspective view of a curved blade razor embodying my invention;

Figure 2 is an elevational section taken on the line 2-2 in Figure l;

Figure 3 is a partial elevational section taken on the line 3-3 in Figure 2;

Figure 4 is an exploded front elevational view of an alternate form of razor embodying my invention; and

Figure 5 is a side elevational view of the device shown in Figure 4 with the parts assembled.

In referring to the form shown in Figures 1 through 3, I have designated the handle portion of the device by the reference character I0. The handle I0 is the general shape of a ring split at the top as indicated by the character II in Figure 3. The two end portions of the ring-shaped handle I0 are formed as a transversely divided blade carrier 9 with outwardly projecting rakelike teeth I2 which form the operative edges of the razor as best seen in Figure 1. The purpose (Cl. SBI- 741) of these tooth-like projections I2' is, as is conventional in Vrazors of the general'class described, to contact the skin ahead vof the cutting edge ahead of the rrazor and' stretch the skin Vto khold the hairs upright. The projections I2 also serve to protect the cutting 'edge of the yblade and to prevent the skinI from bunchi-ng and being cut;

The handle I' is constructedof resilient material and normally biased so asjto expandv in the direction of the arrows placed on Figure 3*. When the razor is assembled', suchA expansion isd preventedv by a blade 'holder or guard plate I3 having downwardly projecting andr inwardly* bent hook-like members I4. Since the looped' portion of the handle IIJ-'is lesszin width than th-etotal width of the carrier 9,', thus to form transverse shoulders at the outer ends' of the carrier-'9 where it joins the handle lu,1the hook members I4 are adapted and; positioned' tc engage the shoulders adjacent the ends; of the carrier 3' whereby to hold the handle IU inthe closedv position inclicated in, Figure 3. n y

Betweenthe upper-surface ofthe carrier 9 and the guard plate I3 is, .placed a conventional slottedy razor blade I5. Thus the Arazor is securely clamped: between the guard I3 and' the carrier 9, .being held in thist position by they normal tendency of the handle "I0, to expand the carrier against the hook members I4.

In lorder to properly position the cutting edge of the blade, the' guard plate I3 vis for-med with a downwardly extending and elongated boss 20' which is proportioned to. engage the slot lIaI in the razor blade I5l and properly align the blade with respect to the guard I3. Since the hook portions I 4 which attach the guard plate I3 to the handle I0 align the guard I3 with the handle I0, it therefore follows that the blade is properly aligned with the rake teeth I2. The boss 20 may be formed by coining the guard member I3 as shown in the drawings, or alternatively, may be formed by securing an elongated member to the under surface of the guard I3.

In order to provide clearance for the boss 20, a complemental depressed portion 2l is formed in the adjacent surface of the handle I0.

To assemble the razor shown in Figures 1 through 3, the handle I0 is compressed by manual pressure until the ends at the split II are touching. The razor blade I5 is then laid in position on top of the handle I0 with its cutting edges in approximate position adjacent the teeth I2. The guard member I3 is then placed on top of the blade I5 with the boss 20 entering the slot I5a in the blade and is pressed downwardly to bend the blade into the arcuate shape shown in Figure 3 yand with the hook members I4 extending downwardly beyond the teeth I2. The pressure is then released from the handle I0, allowing it to expand whereby to bring the end teeth I2 into engagement with the hooks I4, thus securing the entire assembly together. Disassembly is, of course, the reverse of the procedure just described.

Thus it will be seen that the only parts required in addition to the blade are the handle III and the guard I3. These parts can be fabricated from stock material of the same thickness and require relatively simple stamping operations to form them. The total absence of screw threads, pivoted parts or other complicated mechanisms makes the razor extremely easy to clean since there are no crevices in which shaving cream, hair cuttings, or other material can lodge.

A modied form of my invention such as would be suitable for men shavers is illustrated in Figures 4 and 5. In the modiiied form it will be noted that the end portions 25 of a modified handle IIO are bent outwardly so as to form a generally T-shaped razor having a looped handle.

A further diiference of the modified form is shown in Figure 5 wherein it will be seen that the blade is curved in its transverse direction. The guard member II3 of lthe modified form is identical to the first form described except that it is not bent longitudinally but is bent transversely as can be seen in Figure 5. The manner of assembling the modified razor is practically the same as in the nrst form, pressure being applied to the sides of the handle Il!) to bring the surfaces 2S into contact whereupon the blade I5 and guard II3 may be assembled and the pressure released to lock the parts in place.

The devices just described may be constructed from various different materials, but stainless steel has been found to be particularly adaptable in that it requires no plating or other finishing operation and will not rust or corrode.

It is contemplated that the radius of curvature of the blade-adjacent portions of the device shown in Figures 1 through 3 may be varied to suit various uses. In the present instance the curvature is rather slight in order that the razor may be used not only for underarm shaving, but may be used to shave other parts of the body as well.

While the devices shown and described herein are fully capable of achieving the objects and providing the advantages hereinbefore stated, it is realized that they can be modiiied somewhat by those skilled in the art without departing from the spirit of the invention. For this reason I do not not mean to be limited to the form shown and described, but rather to the scope of the appended claim.

I claim:

In a razor having a removable blade, the combination of a rectangular carrier for said blade, said carrier being of greater width than said blade and having a plurality of rake-tooth-like projections formed along a lateral edge thereof and adapted to project beyond the cutting edge of a blade held on said carrier whereby to stretch skin ahead of said cutting edge, said carrier being divided along a transverse joint, into two portions, which portions are relatively movable in a direction substantially parallel to said cutting edge; a handle comprising a looped resilient member having its ends connected to said portions and being spring biased whereby to urge separation of said carrier portions, said looped member being further adapted to receive manual pressure to force said carrier portions together; and a guard plate removably secured to said carrier whereby to clamp said blade thereagainst with said cutting edge thereof in operative position, said guard plate having a boss formed therein adapted to engage a slot in said blade whereby to hold the same in said operative position, said guard plate having depending hooks on the ends thereof positioned to engage end teeth of said carrier whereby said separation pressure of said looped member secures said guard plate to said carrier and whereby said guard plate may be removed by said manual pressure applied to said looped member.
