inafter referred to in the specification and further specified in the claims.

In the drawing: Figure l is a perspective view of my preferred form of razor. Fig. 2 is a similar view, parts being separated. Fig. 3 is a vertical section. Fig. 4 is a transverse section at right angle to Fig. 3. Fig. 5 is a detail perspective view of a modified form of guard, or clamp. Fig. 6 is a similar View of a holder to coperate with said guard. Fig. 7 is a perspective view of another form of holder.

The numeral 1, indicates a handle formed at its upper end with a flanged head convex on its upper face to form a holder 2. While the holder is preferably formed with the handle it will be obvious it could be made separate, and secured in any well known manner. An opening 3, extends through the 'holder and down into the handle, and crossing the same near the lower end, and at right angles thereto, is a horizontal opening 4. rIhe opening 4:, extends through bosses 5, on the opposite sides of the handle, which form a To all whom it 'may concern:

l3e it known that I, CHARLES I-I. OCUM- PAUGr-I, a citizen of the United States, residing at Rochester, in the State of New York, have invented certain new and useful Improvements in Razors, of which the following is a speciication.

This invention relates to improvements in safety razors.

Tith the fiat safety razor blades now in use, considerable difliculty has been experia. holder. In many instances the ends of the fingers are cut or scratched, which frequently necessitates applying a sharp implement to pass under the edge of the blade to raise it before taking hold of it with the fingers to position it on its handle. This operation destroys the edges and makes the blade useless. lVhile I am aware attempts have been made to cure 'this difficulty, the margin of success has decreased the merits of the razor edges, and has added to the cost, due to the fact that the thickness of the blade has been materially increased.

One of the prime objects of the invention is to provide a reinforced, substantially curved razor blade of uniform thickness steel to permitof its being conveniently picked up withoutliability of cutting the fingers, and what is equally' important to make a rigid blade of thin sheet metal, the latter overcoming the object-ions of the so called fiexible blade.

Another object of the invention is to provide special means coperating with the handle for securing the parts together, which also enables me to produce a razor with a comparatively few pieces.

Hy invention also coniprehends improvements in the arrangement of the cutting blade and the guard, whereby I may provide double cutting edges with complementary parallel guards, doing away with the usual unsanitary plurality of fingers.

A further object of the invention is to provide a two edge blade, adapted to be used in connection with several types of razors. y

The specic form of this blade is important, in that the means I employ for reinforcing it, permits of the employment of the usual very thin metal used for blades of this type, and also give it additional rigidity.

, Other objects andv advantages will be here- The rod 6, is provided at its ends with heads to limit its movement in the bearing, and between the heads it is reduced to form a shank 7, and is beveled from the shank to its greatest diameter, as at 8.

Extending upwardly from the holder 2, are two studs 9 9, which `coperate with the cutting blade to hold the latter in r`position, and prevent lateral displacement.

The blade 10, is made of sheet metal and is permanently curved in cross-section, and is of substantially uniform thickness throughout exclusive of embossing and corresponds to the curvature of the face of the -holder 2.- Ihe blade is embossed in three places, b, c, in the center of each being formed an opening 11. The outline of the embossing is shown for convenience as, of ring formation, but it is obvious other outlines may be used if desired. The embossing forms a very essential feature of my inaccomplished. -It must be borne in mind that thin sheet metal is used for .the blade, so that the embossing serves as a strengthenin medium, and enables me to lproduce a thin, butrigid blade. The lugs 99, cnform tothe outline of the embossed portions, and when the parts are assembled, the blade is prevented from becoming laterally displaced.

'substantial bearing for a locking rod 6.

vention, as two very important results are 13, indicates a guard, which is curved on l its under side to conform to the curvature of the top of the blade, and has a depending post 14, formed at its lower end with a vertical slot 15, the lower part'15aL equaling the diameter of the shank 7, and has an en-A larged portion b corresponding to the diameter of the rod 6. The side edges 16, of

edges of thesame are two parallel bars 17,

spaced from the edges 16, to provide slots 18, through which the edges of the blades operate.

To assemble the structure thus far described, the guard is inverted, and the post is inserted through the opening in the blade, then. the post is inserted in the opening 3, in the holder until the enlarged portion 15b ofthe slot is' in alinement with the rod 6. The reduced portion 158i of the slot straddles the shank 7, and the rod is now moved laterally and the enlarged diameter of the rod passes into the opening 15", and effectually binds the parts together.

The embossed portions form seats for the lugs 9 9, and the lsocket oropening 3, guides the guard, so that even in assembling the parts, if the blade should by accident. be slightly misplaced it will 'be brought back into its proper relative position when the guard is tightened. The parts'can, therefore, be assembled in th'eir'proper position bv an inexperienced person,and without any liability of cutting-or scratching the `fingers, as the blade is curved and absolutely rigid and can be conveniently picked up. The outer ends of the lugs 9-9, fit against the flat portions ac intermediate the embossmg. e

In Figs. 5and 6, I have shown a slightly different form of guard and blade holder. In this form of the, invention, the blade holder is provided with two openings 20-20 vin addition to the socket 3, and the ard has an auxiliary depending post 21, in addition to post 14. The post 21, engages with both of the openings 20 and 11, in theblade and holder, and they two absolutely prevent the guard and blade swinging horizontally.

(I do not make4 broad claims for the guard as it is covered in a pending application Serial No. l10,989.) Furthermore, by this construction the guard and blade may be used to coperate with either the right or left hand opening in the holder. If desired, I may duplicate the auxiliary post on the guard as shown in dotted lines in Fig. 5, to further insure holding the parts together.

In Fig.)'7, is shown another form of the invention, wherein the` studs 9--9, on the holder are provided with' two reduced eX- tensions 9a, 9a, to enga-gev the openings 11,

rounding the extensions coperate with the liatportions a inside the embossed portions.

This means also serves to combine the rigid feature of the invention, and the blade has also curved ends which extend beyond the guard body to facilitate its removal. The extensions may be made sulliciently long to pass entirely through the openings in the blade, to engage seats in the guard if found desirable.

The invention is extremely simple in construction, and by reason of the small number of parts, and the shape and disposition of the same, is not liable to get out of order, and may be assembled by inexperienced persons.

The guard bars 17 extend beyond the cutting edges of the blade, so' that in handling `the r'azor a persons lingers are always protected, which is of the utmostimportance 'with a device of this character, especially in assembling.

The guard construction, and the .coperating relationship of the blade and its holder A.

when assembled, produces a sanitary razor, the usual large number of fingers used for guards in razors of this type having been found wanting in this particular.

By constructing the blade as described, it is interchangeableand is 'therefore applicable to any of the above modifications. This feature is important, as a dealer may carry one line of blade for customers having differentstyles of razors.-
