SAFETY-RAZOR.

936,654. Spe ific on Letter a ent Application filed. December 18, 1907. Serialbl'o. To all whom it Be it known that I EDGAR H. MoIN'rIRE, a citizen of the United States, residing lhnois, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.

' his invention relates to improvements in safety razors and more particularly to that type employing a detachable and reversible blade, and the primary object, of the invention is to provide an improved handle for the blade, and improved the blade to the, handle.

A further object is to provide an improved holder comprising a guard plate and a detachable handle adapted to secure the parts together.

A further object is to provide an improved older comprising two separable members means for securing bers comprising an elastic handle, the elasticity of which serves to secure the blade to the other member and in position for use.

A further object is to provide improved means for securing the blade to the holder wherebythe blade may be stropped without removing it from the holder.

A further objct is to provide an improved device of this character which will be simple, durable and cheap in construction and effective and eflicient in operation.

To the attainment of these ends andthe accomplishment of other new and useful objects, as will appear, the invention consists in the features of novelty in the construction, combination and arrangement 'of the several parts hereinafter more fully described and claimed and shown in the an exemplification of the IHVBIItlOIl, andin which Figure l is an elevation, partly in section, of an improved device of this character constructed in accordance with the principles of, this invention; Fig. 2 is a top plan view of Fig. 1 partly in section and partly broken away. Fig. 3 is a detail sectional view on line 3--3 of Fig. 2. Fig. 4 is a detail perspective view of one of the extremities of the elastic handle. k

eferring more particularly to the drawing and in the present exemplificat'ion of the invention, the numeral 10 designates the razor blade, .which may be constructed of I any suitable flexible at Ch cago, in the county of Cook and- State of" substantially be secured together for use, one of the memaccompanying material, such as thin sheet steel having a uniform thickness and provided with two op ositelongitudinal cutting edges 11. The b ade is preferably provided with spaced apertures 12 in its'body portion located between the cutting edges 1d. and adjacent the extremities of the bladef he niuneral 13 clearly in Fig. 3 of the drawing, and this guard is of substantially the same width as the width of the razor blade and is provided with spaced teeth l3 along its longitudinal edges, which project beyond the respective cutting edges of the blade in the usual manner to protect the skin of the user from being cut during the operation of shaving. The longitudinal edges of the guard are preferably the same length as the cutting edges 11 of the blade and the guard is provided'wit h spaced apertures 14.- located at the longitudinalcenter thereof and adjacent the extremities of the guard and these apertures are adapted to respectively register with the apertures 12 in the blade 10 when the blade and guard are placed toge'ther.

The handle 15 is froma single piece of t as metal or the like, bent into a suitable shape to form spaced arms 16, the extremities 17 of which are provided on their outer elastic material, such ticity of-the material from which the handle the arms l6'spaeed from each other a distance slightly greater than the distance between the apertures 14 in the guard and the apertures 12 in the blade, so that when the blade 10 is placed upon the guard 13 in such a position. that the in will register,'the extremity of the handle must compressed tothe position shown 1n dotted lines in Fig. l of the drawing to perk to be inserted into the mit the extremities registering apertures' After being inserted the extremities and the elasticity of the handle Wlll tend to separate the arms 16 and wh le the arms are eing separated, the reslliently mount ed wedges having the inclined faces 19, Wlll draw the blade 10 into close contact wlth the guard 13, causing the blade to conform to the contour of the adjacent face of the guard,

thereby locking the blade and guard screspective apertures thereof the handle are released Patented Oct. 12, 1909.

designates the guard which 1s preferably concave, as shown more preferably constructed faces with wedge-shaped notches 18 to form 7 an inclined or beveled face 19. The elashave been thus specifically described; but

- cu'rely 'together, the notches 18 serving also to prevent the blade and guard from being displaced with relation to ,thehandlef A When it is desired to remove the blade, the end of the handle adjacent the guard may be compressed to the position shown in dotted I lines in Fig. 1 to relieve the guard and blade ,of the strain exerted by the tension of the handle thereon and 'to move the inclined f faces 19 out of engagement with the blade,

so that the extremities 17 of the handle may I be drawn through'the apertures.

It will-be apparent that a razor of this construction may bereadily collapsed for cleaning and for any other purpose and when so collapsed may be packed compactly in a minimum space.

Any suitable mater al may be used for the guard and. handle and by constructing the handle so as to serve the doublefunction'ofa handle and the means for securingthe guard and blade together, it will be apparent that a very sim le device is produced and one which may e manufactured at an extremely low cost. I

The extremities 17 of .the arms 16 are rounded, as shown, and project for only a slight distance beyond the outer face'of .the

blade, which presents a substantially flat surface, thereby permitting the side of the blade to be held in any desired position and in close contact with the face of the user.

It'will be apparent that with this-improved construction the blade may be readily stropped withbut being, removed from the handle, as the extremities 17 of the handle What I claim as newand desire to secure by Letters Patent is- 1. In a razor, the combination with a blade and a guard therefor, said blade and guard being constructed of resilient materlal contactmgalong opposite edgesand rovided with non-conforming lateral suraces intermediate of said contacting edges, and a resilient handle one end of which is provided with wedges engaging the outer surfaces of said blade and guard toforce the contiguous surfaces thereof into close"contact.

2. a razor, the combination with a blade and a guard therefor, of resilient material,

said blade and guard being in contact along opposite edges -'and-.provided .with nonconforming lateral surfaces-- intermediate *thereto, and a resilient'handle one end of whiclr s provided with oppositely mounted we dges for engaging the outer surfaces of said blade and guard to force the contiguous surfaces thereo into close contact.

3. In a razor, the combination of a blade provided with spaced apertures, and a bandle, one end of which comprises spaced yielding members adapted to be inserted into the apertures, each of said members being pro vided with a recess in its outer face adjacent the extremity thereof and adapted to receive-the edge of the respective aperture, andsaid apertures being arranged to exert a tension on the members to secure the parts together, the extremities ofthe said members beyond the recess being rounded and terminating substantially flush with. the outer face -of the blade.

. '4. Ina razor, the combination with a blade and a guard therefor, said blade and ard being constructed of resilient materia contacting along opposite edges and having non-conforming lateral surfaces intermediate to said edges, and an inte al handle of resilient material, said hand e being provided witlnadjacent and oppositely disposed wedges engaging the outer surfaces of said blade and ard to force thecontiguous surfaces of said blade and guard into close con tact.

5. Ina razor, the combination with a resilient blade and a resilient guard therefor, said blade and guard being formed with non-conforming lateral surfaces, and an integral handle of resilient material having ad- "jacently disposed extremities, said extremities being provided with .wedge shaped notches for engaging t e outer lateral surfaces of said blade an guard to force the contiguous surfaces of the sameinto close contact.

6. In a razor, the combination of a blade provided with an aperture, a guard'also provided with an aperture ada ted to reg1ster with the aperture in the bla e when the two are placed together, and a handle, one extremity of which is adapted to be inserted in the registering apertures and engage one a face ofeach of the members for securing the .parts together.

7. In a razor, the combination of a bladeprovided with spaced apertures;a guard also provided with spaced apertures. adapted to register with the apertures in the blade when the two are laced together, and a handle, one end .of w ich comprises spaced yielding extremities adapted to be inserted into the registering apertures for securing the parts together, the apertures a tension upon-the said yielding extremities.

8. Ina razor, the combination of a blade; provided with spaced apertures, a guard also provided with spaced apertures adapted to register with the a ertures in "the blade whenthe two are paced together, and a handle, one end of which comprises-spaced? V bemg'spaced to exert adapted to be inserted into the registering apertures for securing, the parts together, a portion of the said extremities being adapted to engage one, face of each of the members and said apertures being spaced to exert a tension upon the said yielding extremities.

In a razor, the combination of a blade provided Wit-h spaced apertures, a guard, also provided with spaced apertures adapted to I register with the apertures in the blade when l the two are placed together, a handle, one, end of which comprises spaced yielding extremities, each of which is provided with a notch having an inclined face, said notches being adapted to receive the edges of the, blade and guard adjacent the respective apertures and said apertures being spaced to ex- 1 ert a tension on the extremities of the handle I' to cause the inclined faces to engage one of l the members and clamp the same against the other member to secure the parts together. i
