4 Claims. (01. 30-34) This invention relates to safety razors. One object of my invention is to provide a safety razor having a face rest on the upper portion thereof, in such relationship to the edge of the blade as to cause the skin to bulge inwardly between the rest and the edge of the blade, thereby presenting the hairs of the beard at the most favorable angle for cutting, yet without the danger of cutting the skin.

Another object is to provide .a safety .razor of this type, having a .face .rest of an anti-friction character so that the rest reduces the friction between the razor and the skin, and also massages the. latter asit passes over the face.

Another object is to provide a safety razor having a guard on one side of the blade and a cover plate on the other side, together with a roller mounted on the cover plate at a greater distance from the edge of the blade than the latter is from the edge of the guard.

Another object is to provide a safety razor of the above-described type, either with a single or a doubleedged blade, and having a roller substantially in the center of the cover plate so: as to provide a face rest adapted to cause the skin to bulge inwardly into the space between the rest and the edge of the blade, thus increasing the efficiency of shaving and permitting a closer shave by presenting the bases of the hairs of the beard at the most efiicient angle to the razor blade.

Another object is to provide such a face rest on a safety razor, so mounted as to be adjustable in its position, thereby enabling the razor to be adjusted to meet the most efiicient conditions of shaving as effected by the face, skin and beard of the particular individual.

Anotherobject is to provide a safety razor having a roller of the above-described type, wherein the surface of the roller is roughened so: as to prevent accidental cutting by reason of the slippage or" the razor transversely to the intended direction of out.

Another object is to provide such a safety razor as described above, employing a multiplicity of coaxial rollers.

In the drawing:

Figure 1 is a front elevation of a safety razor according to my invention.

Figure 2 is a plan view of the safety razor shown in Figure 1.

Figure 3 is a side elevation .of the upper portion of the safety razor shown in Figures 1 and .2.

Fig-ure 4 is a front elevation of the upper portion of a modified form of safety razor, employing a plurality of coaxial rollers instead of a single roller.

Figure 5 is a front elevation of the upper portion of a safety razor similar to that of Figure 1, but with the surface of the roller roughened.

Figure 6 is a front elevation of the'upper portion of a safety razor similar to that shown in Figure 1, but with a roller the position of which is adjustable relatively to the remainder of the razor.

Figure '7 is a side elevation of the razor shown in Figure 6.

Figure 8 is a side elevation of the upper portion of a safety razor similar tothat shown in Figure '7, but with the adjusting means so arranged that the roller is adjustable in an oblique direction so as to change its distance from the edge of the blade, as well as its height above the cover plate.

Referring to the drawing in detail, Figure 1 shows the safety razor of my invention in its preferred form, as applicable to a double-edged form of blade. .It will be understood, however, that the same invention is also applicable to a safety razor employing a single-edged blade, the double-edged form being shown by way of illustration.

The safety razor of the form shown in Figure 1 consists of a handle I, on the upper portion of which is mounted a guard 2, having a cover plate 3. .Between the guard 2 and the cover plate 3 is arranged a blade 4 having edges 5.. The edges of the guard 2 may be cr-enelated so as to provide notches B, the latter serving to present the blade -more efficiently to the beard andalsoto permit the passage of thesoaptherethrough.

The cover plate 3 is provided with a lower surface I, of partially arcuate cross section, ap proximately corresponding to the upper surface 8, of approximate arcuate cross section, on the guard 2. The coaction of these surfaces causes the blade 4 to be arched when the guard 2 and cover plate 3 are forced together, as by turning the handle I. The latter is preferably provided with a screw threaded junction connecting it to the cover plate 3 (not shown). The cover plate 3 may be also .providedwith a ridged portion!) adapted to engage a corresponding socket or groove It] in the guard 2. The purpose of this construction is to engage the blade and prevent the turning thereof when the razor :is used or adjusted. Mounted upon the cover plate 3, at a location substantially in line with the handle I, are ears ll serving as brackets and having holes l2 therein to receive the axles it of a roller M.

In the operation of the safety razor of my invention the razor is placed with the roller resting against the skin, shown at IS in Figure 3. It will be observed that the razor touches the skin at the edge Iii of the guard 2, and also at the periphery I! of the roller 54 (Figure 3). It will be further observed that the contact point I! of the roller 84 is located at a considerably greater distance from the blade edge 5 than the contacting edge 16 of the guard 2. With this arrangement the skin bulges inwardly into the space between the guard edge l6 and the roller periphery i? so that the blade edge 5 is presented at the most favorable angle to cut the base of the whisker l8 (Figure 3), yet without cutting the face in so doing, as might occur with the roller I4 situated close to the blade edge 5.

The razor is held in the position shown in Figure 3 and moved downward over the face. The soap passes between the notches 6 in the edge of the guard 2, together with the severed whiskers. Substantially none of the soap gets past the edge 5 of the blade 4, hence, the action of the roller 14 is not impeded by said soap getting into its bearings. The roller l4 thus massages the skin as the razor is moved along the face, a very slight pressure being necessary to accomplish this.

It is to be emphasized that my invention, with the roller above the blade, is to be distinguished from the use of a roller below the blade and near the contact edge it of the guard. My roller H5, in cooperation with the guard edge l6, provides a bridging of the skin so that it bulges into the space between the two places of contact, and presents the whiskers at a favorable angle for cutting without also cutting the skin. The use of a roller in place of the guard edge I6, or mounted at a similar location, will not accomplish this purpose but, in contrast, tends to impede the action of the razor by preventing the soap from passing beneath the guard. In my razor, moreover, the roller I4 permits the razor to be slid easily over the face with a great reduction in the friction which ordinarily occurs between the razor plate and the skin.

It will be understood that while the safety razor of my invention is shown as constructed of metal it may also be constructed of any other suitable material, such as a plastic, this being especially true of the roller M.

In the modified form of safety razor shown in Figure 4, the construction is essentially the same as that shown in Figure 1, except for the fact that instead of the single roller M a plurality of rollers is mounted upon the axle l3. This feature permits one roller 20 to turn more rapidly than the others. ent in turning the razor to round the corners of the jaw or to accommodate other facial irregularities.

The modified form of safety razor shown in Figure 5 is similar to that shown in Figure 1, with the exception of the fact that the surface 2| of the roller I4 is corrugated, or otherwise roughened. This feature prevents the razor from slipping transversely to the intended direction of cut, thereby preventing serious accidental cuts of the skin, which often result from such slippage. At the same time, the passage;

This action is conveniof the razor along the face is facilitated by the anti-friction mounting of the roller 2| in the bearings [2 on the ears II. The corrugations also enable the surface of the roller to grip the skin more readily than in the case of a smooth roller.

The modified form of safety razor shown in Figure 6 is generally similar to that shown in Figure l, with the exception of the fact that the ears H are provided with slots 22. The axle 23 has an enlarged body portion and reduced ends 2 2, which pass through the slots 22, thereby forming shoulders as at 25. These shoulders project slightly beyond the ends of the roller 26 which is provided with a bore 21 loosely fitting the body of the axle 23. The ends 24 of the axle 23 are threaded to receive knurled nuts 28.

When these nuts are tightened the shoulders 25 come into engagement with the inner surfaces of the ears H, the slight clearance between them and the ends of the roller being sufiicient to permit the roller 26 to turn freely upon its axle 23. At the same time the position of the roller 26 may be adjusted by loosening the nuts 28 and sliding the axle 23 up and down until the desired position is reached, whereupon the nuts 28 may be turned in order to lock the axle 23 in a fixed position. A washer may be used, if desired, between each nut 28 and the ear II which it engages.

The modified form of safety razor shown in Figure 8 is similar in principle to that shown in Figure 7, but possesses ears 29 having approximately arcuate slots 30 therein. The construction of the roller and its axles is otherwise similar to that shown in Figure 6. The purpose of these arcuate slots 30 is to enable the position of the roller 26 to be adjusted, both vertically and horizontally at the same time, with reference to the edge 5 of the blade d. Thus the distance between the contact points of the blade edge 5 and the roller 28 may be adjusted together with the height of the roller 26 above the cover plate 3.

It will be also understood that in place of the roller moving up and down in a slot 22, as shown in Figure 7, the roller may be immovably mounted therein, as shown in Figure 3, the ears being slotted in their lower portions and adjusted by screws extending through these slots into the ends of the cover plate 3.

I desire to comprehend within my invention such modifications as may be embraced within my claims and the scope of my invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a safety razor, a double-edge blade, a guard, a cover plate, a handle, and an antifriction member adjustably mounted on said cover plate approximately in line with said handle for adjustment sidewise of said blade, said anti-friction member consisting of a plurality of freely rotatable coaxial cylindrical rollers.

2. In a safety razor, a double-edge blade, a guard, a cover plate, a handle, and an antifriction member mounted on said cover plate approximately in line with said handle for adjustment with respect to said blade, said antifriction member consisting of a plurality of coaxial cylindrical rollers, said rollers being freely rotatable independently of one another.

3. In a safety razor, a blade, a guard, a cover plate, an anti-friction member mounted on said cover plate, and means for adjusting the position tion of said anti-friction member relatively to said cover plate in an oblique direction, whereby to simultaneously vary the distance of said member from the edges and center line of said blade,

said means comprising arcuately slotted mem- 5 bers adapted to adjustably support said member.
