SAFETY RAZOR.

Application filed August. '2, 1927. SeriaI No; 210,117.

This invention relates-to safety razo'rsand is more particularly concerned with the pro-- vision of a razor structurally economical for" manufacture and functionally advantageous for use.

An'object of the invention is to provide a razor comprising a blade holder structurally simple and capable of manufacture by the metal stamping operations so largely used today, which holder embodies certain novel and advantageous features hereinafter pointed out and efiective to improve the shaving operation. I

As used today, the highest cutting eh iclen'cy of the razor blade is prevented by the accumulation thereon of lather and hair. The lather has performed its task before the blade reaches it and it is not necessary to the edge of the blade in its hair severing action. While from the standpoint of every-day and every- Way use of safety razors, it is impossible, practically, entirely to prevent the accumulation of lat-her upon the razor edge, the construction provided for by the present invention among its features embodies'means normally tending to prevent such accumulation and effective largely to reduce it. This construction also has an objective, the support of a blade with its edges free and unhampered' by holder cutting edge of the blade and have used a positioning bar which cooperates with the clip edge and leaves the razor edge free and unobstructed. In maintaining a blade so positioned on the holder, he retaining means used is held against displacement by the handle of the holder which is detachable and makes for compactness in the razor. The act of assembling or dis-assembling the razor of the present invention, therefore, results in the clamping or releasing of the blade retaining means.

These and other features will be more clearj ly apparent from the following ,detaileddescrlptlon, -read 1n QOHJHDCUOII W th the accompanymg drawings form ng partthereo'f and in which:

Referring to the drawings :-In the form of the invention shown in Figs. 1-4l and 8, the blade holder comprises opposed platescon nected at their-upper ends and which may be formed bythe nsualexpedient of bending a strip of-metal upon itself. The uppermost plate 1 of the two constitutes the razor blade backing plate and the lower or underplate 2 connected therewith at thetopis preferably formed centrally with a pocket 3 therein by upsetting the material in a suitable press, this providing at this point, an offset in the rear plate This offset portion is reversely, upset to provide a handle socket 4t and inwardly extending boss 5 in continuation. This boss terminates a short'distance from the rear is a vertical section on line7- 7 of or bottom face of'the blade backing plate 1 and the upperorjunction edgeof the plates 1 and 2 are formed with an elongated slot 6 therein. Adjacent to the bottom edge of the blade backing plate 1, an upstanding blade positioning bar 7 is appropriately connected I to its edges, as by welding, and is spaced from its face to overlie an nserted razor blade 8 of the single edged variety, therear or noncuttingedge of which is provided with the Y Y Fig. dis a detail perspective of the blade usual metal clip 9. The upper edgeofthe positioning bar? engages the lower edge of the clip 9 and det'erminately positions the lower cutting edge ofthe bladev I The blade is held in cooperative relation to the positioning v :and may be stamped out therefrom.

guard, the edges or which torina bn clipped edge of the blade and with its inner arm 12 extended through the elongated slot supported blade is the guard bar 1%, which in the form shown in Figs. 1-l presents an unbroken rectilinear skin contacting edge 15 in, advance of thecutting edge of the blade and an adjacent lather collecting body portion 16. The bar 1% is ofsubstantial'width relatively to its thickness to provide for the accumulation of a reasonable amount of lather ahead of the-blade which as will be seen, is supported by the holder with its enti e cutting edge unobstructed. .The guard edg l l is forward from this cutting edge so that the -lull width of the blade is available for shaving. The operation is facilitated and t he tautening of the flesh in advance of the blade edge is etl'ected by the unobstructed edge of the supported blade and the rectilinear edge of the guard in cooperation. The action simulates closely that which occurs when shaving is eil'ected by the so-called old fashioned method of straight blade? razor and hand "tautened skin. The guard bar 14 is connected to the plate 3 by any appropriate means. As shown,

' one such meansrnay be in the term of depending arms 1? connecting the edge of the plate 3 andthe contact edge ofthe bar. It will be obvious that the bar and connecting arm 17 may constitute an integral part ofthe .plateg The arms 17 are preferably corrugated. as shown In the form of the invention shown in Figs. 57, the construction is, in es sence, modified as regards the form of depending guard member only. Similar numbers as those employed in Figs, 1 to l-there fore designate corresponding parts oi the structure. The modified torin of guard member is provided by a series of approximately semi-circular teeth 18 (Fig. 7) which may beanintegral part of the rear plate 8 or handle receiving member of the holder and similarly to the bar guard 14 first eescribcd, may be died out, from the sheet metal oi? the holder or otherwise appropriately formed The approximately circular metal o the tilinear contact edge positioned in adv the cutt ng edge of the razor blade, provides a lather pocket into which a substantial por-' tion of the lather in advance of the blade will be drawn during the shaving operation. The

' curved body of the blades therefore provides a lather collecting body portion for the guard 'i'ront edge of similarly to the face 16 01" the guard barle of the first iorm descrlbed.

The advantages achieved by the described constructions have been previously discussed in full and need not be repeated. The disclaim and desireto secure by Letters Patent attached to their ear edges, a blade holder having his forward edge provided with a raised cross bar arranged to engage the front edge oi the clip of a razor blade and to position said blade with its full cutting edge en tirely free and unattached, and a guard conected with the holder and having its guard edge positioned in advance of the cutting edge of the blade and out of contact therewith.

In a safety razor for blades having clips attached to their rearedges, a blade holder having a blade backing member with a cross bar at its front edge upstanding from its lace to overlie a razo'r blade and to engage .the clip and position the cutting edge of the blade forwardly of said backing member and entirely free and unattached,
