Filed Dec. 27, 1943 3 Sheets-Sheet 3 Patented Feb. 5, 1946 UNITED STATES PATENT FFICEy SAFETY RAzoa Georges Monnet, Washington, D. C. Application December 27, 1943, Serial No. 515,728 (o1. 30-70) Y 6 Claims.

This invention relates to razors and refers more particularly to safety razors which do not have to be taken apart and reassembled in the course of their use.

Safety razors now on the market consist usually of at least three pieces which have to be taken apart and reassembledV whenever it is necessary to insert a razor blade or remove it from the razor.

So called one-piece razors, now in use are comparatively complicated and easily breakable, and cannot be used satisfactorily with two edge blades.

An object of the present invention is the provision of a one-piece safety razor which is simple in construction and effective in operation. i i

Another object is the provision of a safety razor which does not have to be taken apart or reassembled for the purpose of inserting a razor blade therein or for removing that blade, and which is simple and sturdy in construction and effective in operation.

, A further object is the provision of a one-piece safety razor, which is so constructed, that the blade supporting surface may be conveniently exposed for the purpose of placing a blade thereon, whereupon the blade is clamped between this surface and a cover. y

Other objects of the present invention will become apparent in the course of the following specification:

In accomplishing the objects of the present invention, it was found desirable to provide a blade support which is rotatably mounted upon a handle and which cooperates with a cover movable in relation to the blade support upon guides which may constitute a part of the handle and/or of the blade support. Y

The clamping of the blade between the blad support and the cover may be attained through the use of a screw thread engagement between the cover and a portion of the handle.

The invention will appear more clearly from the following detailed description when taken in connection with the accompanying. drawings showing by way. of example, preferred embodiments of the inventive' idea.

In the drawings:

Figure 11 is an end view of the razor shown in Figure 10.

Figure 12 is an end view of the razor its inoperative position.

Figure 13 is a section along the line .I3- I3 of Figure 10.

The safety razors shown in the drawings 'may be made of metal, wood, plastics, or any other' suitable material.

The razor shown in the Figures 1 to 5, has a handle 20 which maybe of any-suitable shape, and which has an upper neck portion 2| carrying a pivot 22. f y

The lower end of the pivot 22 is rmly embedded in the neck portion 2l. The pivot 22 carries a ange 23. pivot 22 is provided with screw threads.

The blade support consists preferably of two parts in order to facilitate assembly around the flange 23. The two parts may be of substantially the saine form in order to simplify manufacture.

The lower part 25 is pivotally mounted upon the pin 22 and rests upon the upper end of the neck portion 2|. Y

Central recesses formed in the supportingpart 25 receive the lower part of the flange 23 and the adjacent portion ofthe pivot 22. The support 25 has curved lower surfaces and a flat upper head in surface which is engaged by a corresponding surface of the upper support portion 26. The sup port portion 26 has central recesses receiving the upper part of the flange 23 and the adjacent end of the pivot 22. The two support portions 25 and 2S are connected with each other and may rotate upon thepivot 22. y j

The upper surface 21 of the support 26 may carry

projections

28 and 29 fitting into the central slot 30 of a razor blade 3l. The threaded end 24 of the pivot 22 is so dimensioned that it extends conveniently through `the same central opening 30 of the blade. ,Y u

Then, the cover 68 may be swunggback into its position directly above the blade, whereupon the cover is moved downwardly and the pivot end 52 is screwed into the Ybore hole 62. The boltV heads 51 and 58 will be introduced then into the

openings

63 and 64 of the cover 60'. In this construction the relative swinging movement between :the cover"4 60 :and the-'supporting members, facilitates the-removal vandfthe inser- The cover portion 32 is carried by two supports p /tion of the blade.

The supports 35 and 36 are joinedfby'afyokel 391 g having a middle ring portion 40-embracing the neck portion j2| of the handleZU." The supports' 35 and 36 and the yoke `39 are comparativel-ynar'e, row .and may be conveniently grasped bythe n'ger's' of the user for the purpose of'manipulat-` Y ing the cover 32.

The `pivot end 214 is screwed into the hole` 33 and the blade is rmly clamped between the supportl 26 andthe coverv 32. Y

Invorder to removev the blade, the user turnsf the handle 20. untilthe pivot end. 24; is withdrawn from 'the threaded hole "33.7 ,Then-,1 the ,cover 32 may be raised upwardly withthe supports 35 and 36 sliding in the grooves 3'1`and-38 and the ring 40 moving upon the neck portion. 2|.

The safety razor shown in FigureslO to 13 has ahandle 10 provided with an upper cylindrical y'portion 1| which may be narrower than the hanf `dlefmgandwhich contains two grooves 12 and 13 vdisposed on opposite sides thereof. 'I'hese grooves contain thev disks"1f4"and 15 respectively, which lar bar 11 `is-attached to the'disk1-5. n Y "The cover 18' of the razor carries downwardly can slide-and 'turn in the grooves. `The disk 14 is connected to a transverse bar 16, while a, simiextending vbrackets if 19 'andi 80 which fare; con- 18andf 88 are located ,at a distance from nected with the bars 18 and 11.
