ADJUSTABLE RAZOR Filed March 3, 1943 ML I Patented Feb. 22, 1944 UNITED STATES PATENT OFFICE Claims.

This invention relates to razors and has particular reference to such devices as are adjustable and adapted for use as safety razors.

One object of the invention is to provide a device of the character described having improved means whereby a plurality of razor blades are operatively held for selective instant use.

Another object of the invention is the provision of a device of the nature set forth having improved means for holding a razor blade, whereby a single means can be employed to hold a plurality of blades in operative position.

Another object of the invention is to furnish a device of the type mentioned having improved means utilized to clamp a plurality of blades to a rotatable head and to clamp the latter in selected angular position to a handle in one operation or by a single or unitary means. Generally stated, it is an object of the invention to provide improved means in a safety razor for holding a plurality of blades of likeor different types or of different degrees of sharpness so that the operator can use any or all of them in course of a single shave by a rapid and simple adjustment, whereby the comfort of the user is served in a high degree.

Other objects and advantages of the invention will become apparent as the specification proceeds.

With the aforesaid objects in view, the invention consists in the novel combinations and arrangements of parts hereinafter described in their preferred embodiments, pointed out in the subjoined claims, and illustrated on the annexed drawing, wherein like parts are designated by the same reference characters throughout the several views.

In the drawing:

Figure 1 is a view in side elevation showing a razor embodying the invention.

Fig. 2 is a sectional view approximately on the line 22 of Fig. 1.

Fig. 3 is a view in front elevation of the head, and certain related parts.

Fig. 4 is a diagrammatic view showing of an inclined blade as applied to the end clamp plates shown in section.

Fig. 5 is a similar view of a straight held blade as modified for marginal engagement with the clamp plates.

Fig. 6 is a diagrammatic fragmentary, sectional view of another modification.

Fig. 7 is similar View of still another modification.

The advantages of the invention as here outlined are best realized when all of its features and instrumentalities are combined in one and the same structure, but, useful devices may be produced embodying less than th whole.

It will be obvious to those skilled in the art to which this invention appertains, that the same may be incorporated in several different constructions. The accompanying drawing. therefore, is submitted merely as showing-the preferred exemplification of the invention.

Referring in detail to the drawing, 6 0 denotes a safety razor embodying the invention. The same may include a generally U-shaped handle l I, comprising a cross bar 12, which may have a finger piece or secondary handle i3 rigidly connected thereto. A screw or rivet it may pass through the bar #2 and the'arms [5 to pivotally frictionally connect the latter so that the handle structure is adjustable to different angles. Thus the finger piece i3 is shown at a selected angle to the arms 15.

At the opposite end of the handle H is a head 16, at opposite ends of which are disposed disclike clamping plates H which are convexed for stiffness. Passing axially through the clamp plates H and the head iii is a screw means, comprising a screw it which also extends through the arms iii. A wingnut E9 or the like may be used to apply a desired clamping pressure. Since the head and the disc plates are located between the arms 25, the latter become the jaws of a clamp whereby the plates H are pressed toward each other to engage the head or such razor blades as may be carried thereby. Hence the head is rotatable to any desired position of adjustment relative to the handle, in which position it may be secured by the tightening of the win'gnut. single blade or with a plurality of blades to bring a selected blade to operative position or. to move a particular blade into difierent operative positions.

The blades constitute the means which assume the clamping pressure referred to, whereby a plurality of blades can be simultaneously secured and the head retained in the adjusted position. Thus one or more razor blades 2|, 22 and 23 may be used, the

blades

21, 22 being desirably of the 'same length, while the blade 23 may be of the inclined or angularly positioned type shown in Fig. 4. To prevent the blades from buckling they are partially received in corresponding slot openings in the head Hi. If a minute buckling occurs it will'notafiecttheblades, but will serveto en- Sucn adjustment may be used with a hence their frictional engagement in their slots; such engagement may be free or afiord a snug fit. In any event a further advantage is obtained because a one-piece head may be used for a plurality of blades. Even the guards may be integral with the head, including guard portion 24 for blade 2|; opposed

guard portions

25, 26 for blade 22 forming a relatively wide trough with the blade edge central thereto; and guard portion 21 for blade 23, angularly positioned to correspond with cutting edge of the blade. It will be noted that the guards may be of any well known type. The action of blade 2! is conventional, but blade 22 has a superior shaving action because the

guards

25, 26 facilitate stretching the skin while avoiding any obstruction of the blade edge. The blade 23 affords an improved shaving by reason of angular cutting of the hairs, so that a smooth shave is obtained with a minimum dulling of the blade edge. It will be observed that the blades lie at any suitable acute angle to the tangent of the body Hi. With the blade 23, it is desirable to obtain an improved anti-slip engagement with the plates ll, for which reason this blade may be notched out at 28 so that the edge portions of the concaved discs I! shall engage therein. These notches may be sufficient in length or size to enable the edge portions of the discs ll to be received therein when the blade lies in an angular plane as shown. The other blades such as 2| and 22 need not be notched, or they may be so notched as shown at 29 in the modified blade 3|] of Fig. 5. In either case the discs l1 may be uniform throughout and can engage blades at any peripheral point.

A modification in part of the idea above described is illustrated by the razor portion 3l Which may include a double edged blade 32, and a cap or plate 33 therefor. The head [6 may afford a cooperative convex seat with pins at 34 to engage in openings, the razor portion 3| being regarded as including the guards at 24 and 26, and being conventional in construction and mode of operation, except as herein indicated and with the cap secured by the disc plates I! in the same general manner as the blades such as 2!. Desirably the edge portions of the cap may be beveled off or may be notched like the blade 30 at 29 for improved and strong securement by the discs l1. Thus no independent fastener need be used for the cap, although one can be employed if desired. Thus it is seen that the principle of the invention is applicable to pressure on plates includes blades and holders therefor along the planes thereof.

In Fig. 6 is shown a modification in which the lates Ila may be formed with annular confronting flanges 35 of like diameter, all blades being correspondingly notched for engagement with the flanges, as illustrated by blade 36, notched at 31.

In Fig. 7 is shown a modification 38, comprising disc plates I'ib having plane annular portions 39 for engagement with the ends of blade 40 or the like.
