This invention relates to Safety razors and blades therefor.

An object of the invention is to provide a simple., inexpensive and compact safety razor that may be used and cleaned and the blade renewed with a minimum of care and effort.

Further objects of the invention are to provide a safety razor strip that may be drawn into position to provide a continuous successi on of razor lengths; lto provide a safety razor in which a continuous lengthfof blade may be stored and easily drawn at will to a position to expose successive lengths; to provide a safety razor of the above type in which lf the razor length or strip of blade is protected from moisture and rust, and to provide means by which the used length of blade may l be easily detached and in which the new portions of the blade may be securely held.

'20 With these and other objects in View, the invention comprises arazor and the razor blade described in the following specification and claims. l

The various features of the invention are illustrated in the accompanying drawings in whichl Fig. 1v shows a side View of a safety razor v embodying a preferred form of invention;

tempered steel is sharpened to razor keenness at one edge and serves'as a continuous length of razor blade. This strip is coiled and contained within a flat magazine from which it may be withdrawn 'as desired through an opening in the periphery of the magazine providedv with a suitable water-prooforI moisture-proof gasket to prevent the entrance of water or moisture into the magazine.

A' razor blade supporting surface is provided at the periphery of the magazine adjacent the opening through which the blade is withdrawn and in position to enable the ex-` posed length of blade to be laid on this supporting surface and project a distance therebeyond. The projecting part of the'blade is guided at the periphery beyond the supporting surface.

'Aguard is so mountedv on the magazine that it may be brought downwardly on the eX- posed razor blade to hold it in position and is provided with means to detach that part-of the blade that has been drawn past the bladesupporting surface.

Referring more particularly to the accompanying drawings, a long strip 10 of tempered steel, having one edge sharpened. to razor f keenness as at 11, is coiled and positioned Fig. 2 is an edge View looking-from the within a flat magazine 12. The magazine 12 is formed r`with vapair of side walls 13 and 14 having depressed central portions 1,5 and 16. The coiled portion of the strip 10 is positioned between a pair of annular Celluloid v plates 17 and 18 encircling the depressed portions 15 and 16 in the magazine.

,The wall 13 is extended at its periphery to form a peripheral wall 19 and the side wall 14:

is similarly extended to form an inner peripheral wall 20 adapted to lit within the wall 19. The wall 2O may be detachably secured Within the wall 19 but it is preferred to have it permanently secured therein after the strip l0 has been placed within the magazine to ensure against re-illing of the magazine when the razor strip has been completely used.

The strip 10 may be drawn through an opening 21 formedin the peripheral Walls 19 and 20 and positioned at the right end of a flattened razor-supporting length or iattened arc 22 in the outer peripheral wall 19.

A length 23 of the razor strip may be drawn through the opening 21 as shown 1n Fig. 4 and then bent to lie flatly against the razor-supporting surface or arc 22 and to project on to a peripheral surface 24 beyond the razor-supporting length 22.

A pair of guide projections 25 and 26 are formed on the surface 24 within which the projecting part of the razor strip is guided. A notch 27 is also formed in the peripheral wall between the razor-supporting length 22 and the guide length 24.

^ The projecting portion 23 of the razor strip is held in position on the supporting length 22 and guide length 24 by means of an angularly shaped guard 23 hinged to the side Walls 13 and 14 at Y29 and having a iattened or arc-shaped length 30 adapted to fit the razor-supporting length 22 and hold the razor strip tightly thereon. A length 31 at an angle to the length 30 is adapted to overlie the guide length 24 of the magazine and to hold a projecting length of razor blade tightly thereagainst. lhen in closed position, the guard 28A may be secured by means of a latch 32 hinged'toits free end and adapted to engage a holding pin 33 on the side walls of the magazine as shown in Fig. 1.

` A depression 34 in the guard 2 8 is adapted to enter the notch 27 in the peripheral wall of the-magazine and by sharply bending the razor strip at this point to break or sever it as at 35, Fig. 8, so that upon again releasing the guard the severed portion may be thrown away and a new length of strip drawn from the magazine to a position on the supporting arc or length 22. Y y rEhe edge portion of the wall 14 and flange 2O of the magazine is depressed or notched to form a space or groove 36 extending throughout the length 22 to expose the sharpened edge 11 of the razor strip thereon. The peripheral `wall 19 Yis extended and curved downwardly into the depression 36 and is perforated to form a guiding rail or surface 37 inadvance v of the blade 1l and to thus prevent the blade from cutting the skin during shaving.

It will be apparent, however, that any other suitable form of holes and depressions may be used inplace of the speoic one shown in the drawings.

The guard 31 is provided with retaining flanges 38 adapted to enclose the peripheral edges of the walls 13 and 14 and thus hold the guard in position. This flange and part of the peripheral wall of the guard is, however, cut away as at 39 throughout the length 22 to expos the outer edge of the razor strip.

To prevent the entrance of water or mois- -ture throughfthe opening 21` into the magazine, a` gasket 40 of rubber or other resilient material is mounted beneath the -opening 21 vby means of a. suitable clip 41 and is prothe blade strip 23 is drawn, the resiliency of l the gasket tightly closing the opening about the blade and preventing the entrance of molsture. Y

It will be obvious from the above description that in using the razor it is only necessary to release the latch 32, to swing the guard 28 to the position shown in Fig. 4, to then draw a new length 23 of razor stripfrom the magazine, to then fold the withdrawn length of strip over the surfaces 22 and 24 and to swing the guard 28 to the position shown in Fig. l and fasten it with the latch 32.

Various other modifications may be made to be drawn from said magazine into said supporting length and a notch at the end of'said lengthoppositesaid opening and a guard for said 'strip movable to a position to overlie said length and having means to enter said notch to engage and sever the strip therein.

2. A safety razor which comprises a flat magazine Ahaving a -blade-supporting length in its periphery,l an opening to permit strip to be drawn from said magazine into said supporting length and a notch at the end of said length opposite a guard hinged to said strip and movable toa position to overlie said length and having means to enter said notch to engage and sever the strip therein, and

'means for locking said guard in position over said length. -f

3. A safety razor which comprises a flat magazine having a blade-supporting length in its periphery and a guide length at an angle thereto, an opening to permit strip to be drawn from said magazine into said support- `ing length and said guide length and a notch bet-Ween said supporting and guide lengths, a guard hinged toy said magazine in position to overlie said guide and supporting lengths and to enter said notch and means for lockv ing said guard, a strip of safety razor lengths i within said magazine and extending through said opening and a moisture-proof seal in said opening.

5. A safety razor which comprises a fiat length.

6. A compact safety razor comprising a 'i magazine having a attened arc in its periphery and a depression in an edgeof said arc and housing a continuous strip of safety blade lengths, an opening to permit the strip to be drawn from said magazine into a blade supporting length in its periphery, and a notch at the end of said length opposite said opening and a guard for said strip movable to a position to overlie said length and means for entering said notch and engaging and severing the strip therein.

In testimony whereof I hereunto aix my n signature.
