RAZOR.

Application filed November ll, 1916, Serial Ito. 130,722. Renewed May 14, 1923.

To all whom it may concern:

Be it known that LRALPH R. AnAars, a citizen of the United States, and a resident of Yonkers, county of Westchester, State of New York, have invented new and useful Improvements in Razors, of which the following is a specification.

This invention relates to improvements 1n safety razors of the js'o-called ,.wafer blade type which have in recent years come so generally into use.

Such razors comprise essentially a blade of thin flexible sheet steel and'a holder ha"- ing a guard for protecting the edge of the blade and some means for clamping or otherwise securing the blade in place. It has been the observation of users of razors of this type that the blade shaves cleaner near the ends than in the middle. The reason for this is that in using such razors the guard backed by the blade is pressed against the face with an appreciable force so that the razor might be said to be pressed into the face, thereby drawing the skin at the ends of the blade and causing a greater pressure at these points.

It has been attempted to remegy this dep feet by curving the edge of the de so as to have it somewhat wider in the middle than at the ends, but this construction is open to the cost of grindin blades with curved edges is too great to a low the blades to be sold at a price such that they can be discarded when dull. The straight edge blade which is made from a continuous band can be manufactured at much cheaper cost.

The object of my invention is to provide a razor in which ordinary straight edge blades may be used, but which will shave with uniform smoothness or throughout the entire length of the blade.

In the accompanying drawing I have illustrated a razor of common design moditied to embody my improvements, but it will of course be understood that my improvements may be applied to the razors of other design, and that the type is selected by way of illustration only.

In said drawings,

Fig. 1 is a vertical section through therazor with the blade clamped in place;

Fig. 2 is a vertical section parallel with the shaving edge of the razor; and Y Figs. 3 and 4 are detail views of different parts.

serious disadvantage that the.

closeness Referring to the drawings, 1 indicates the main piece or head of the razor which is threaded on the usual handle 2. At its ends the head 1 is provided with upstanding ears 3, the ends a of which are turned inward a short distance, as shown more particularly in Figs. 2 nd 3.

inturned portions of the ears. On the'under' side of the guard piece a transverse rib 8 1s provided in a position to be engaged b the end of the handle 2 where it is screwe into the head.

The ears 3 are provided atthe juncture of the inturned part with the upstanding part with a lug 5 which extends toward the guard piece 6, but sufficiently spaced therefrom to allow the blade 9 to be inserted between the upper face of the guard piece and the under edge of the lug. The blade 9 is provided at each end with notches 10 of a width to receive the lugs 5 when the guard handle is provided with a shoulder 11 at the base of its screw threaded end in a position to engage the under face of the head 1 and limit the upward movement of the guard and blade, as will be later described.

The guard 6"is preferably madeof some elastic metal such as hard brass or steel, which may of course be nickel or silver plated, to prevent corrosion, and provide a suitable finish.

In using the razor the handle is unscrewed suficiently to allow the guard piece 6 to drop against the face of the head so that the blade may be inserted under the inturned portion 4: of the ears to bring its notches in alignment with the lugs 5. The handle is then screwed in, elevating the guard and blade until the blade is clamped between the guard and the portions of the ends 4 which project be ond the lugs. When the handle is screwe in just suficien't to clamp the blade againstv displacement, the blade and guard will .be. straight. The guard, how- .ever, as stated, is formed of 'elastiwmetal and the shoulder 11 on the handle is so positioned that the handle-may be screwed further into the head before the shoulder engages the under face of the head. As the iece 6 is raised by screwing the handle through the head 1 against the rib 8. The.

handle is screwed in the guard and 'blade will be bowed upwardly from the middle or. away from the head, as illustrated in Fig. 2. The shoulder 11 is, positioned to limit the movement of the handle to effect the maximum degree-0f curvature which can be safely or advantageously employed. The blade need not, however, be curved the full amount provided for, but the handle may be screwed in a reater or less degree to suit the individual requirements of the user. The elasticity of the guard piece holds the handle against looseness in its thread in all the intermediate positionsof adjustment.

The lugs 5 hold the razor blade in proper relation to the guard and the inturned ends 4 project sufliclently over the ends of the bladfi to hold the blade in place when bent to t e shoulder 11. Theends 4 should, however, project as little over the ends of the blade as necessary to securely hold the blade thereby leaving the upper face of the blade free throughout substantially its entire length so that it may be readily curved with the guard. l y

In shaving, the razor is pressed against the face with the exposed surface of the blade at a slight angle to the cheek, so that the middle portion ofthe edge first contacts with the skin and under the pressure usually applied in shaving, the entire length of the edge will be effective and instead of shaving close merely at the ends of the blade the entire edge of the bladewill produce a uniform cut.

Another-advantage of my improved razor is that a close shave may be effected in the "hollows of the face,-for instance, in the cleft of the lip. The convex middle portion only of the blade is used andwill fit into the depression and shave clean.

Whenthe razor is taken apart andthe blade removed; it again becomes flat. and may be easily stropped or honed with the usual appliance for the purpose.

it will be understood that my improveeatest curvature allowed by the ment may be applied to razors'of other de sign than that shown, by modifying the except in so far as recited in the appended,

claims. Y

I claim 1. In a safety razor the combination of a flexible blade, a flexible guard therefor and .means for holding said blade and guard in shaving position with the edge of the blade and the adjacent portion of the guard appreciably curved on an axis transverse to the length of the blade and for varying the degree of curvature of said blade and uard.

2. In a safety razor the combination of a flaxible blade and a blade holder comprising a flexible guard, and means for clamping the blade agalnst the aid in close conformity and curving the bade and guard on an axis transverse to the length of the blade.

3. In a safety razor the combination of a flexible blade and blade holder comprising members for engaging the end of the blade, a flexible guard underlying the blade, and means for .elevatin the middle ortionof the guard to there y curve the lade and guard in close conformity on .an axis transverse to the length of the blade.

l. In asafety razor the combination of a flexible blade and blade holder'comprising ,members for engaging the end of the blade,

a flexible guard underlying the blade, and means for elevating the middle portion of the guardto. thereby curve the blade and guard on an axis transverseto the length of the blade, said elevating means being adjustable to different positionsto vary the curva-v ture of the blade and guard.
