SAFETY RAZOR.

Application filed August 4, 1920. Serial No. 401,135.

To all whom it may concern Be it known that L'HARRY Glam BRIER, a citizen of the United States, residing at Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Safety Razors, of which the following is a full, clear, and concise description.

The present invention relates to improvements in safety razors of the so-called hoe type, such as described in Letters Patent No. 1,254,037, granted January 22, 1918, on an application filed by me for improvements in safety razors, and its general object is to provide a device of a simplified and efficient construction, which may be made in a minimum number of operations so as to permit of economical production with a consequent low selling price. v

A further object of my invention isto provide a safety razor as aforesaid, in which the blade clamping element is separable from the blade carrier and is so formed as to cooperate therewith, by the manipulation of the handle of the razor, to rigidly clamp or hold the blade in cutting position relatively to the guard formed integral with the blade holder.

My invention is also directed to a safety razor which, by reason of the construction I and separability of the components thereof,'provides a device which may be cleaned with ease, owing to the accessibility of the various surfaces within which foreign matter might lodge during the usethereof,

thereby providing a razor which will meet the sanitary requirements of the user to the fullest extent.

Other objects and advantages of my invention will become obvious as the description proceeds, and I would have it understood that I reserve unto myself all rights to the full range of equivalents, to which I may be entitled under my invention in its broadest aspect.

I shall now proceed to describe my invention with reference to the accompanying drawings, and then point out with more particularity the essential elements of novelty in the appended claim. In the drawings:

Fig. 1 is a view in elevation of a safety razor made in accordance with my invention;

Fig. 2 is a view in elevation, partly in blade in shaving position.

Fig. 3 is a top plan view of the assembled blade holder with thebladein position therebetween'; I v Fig. 4 is a bottom plan View of the structure shown in Fig. 3;

Fig. 5 is a view looking at the underside of the clamping element, showing the position of the blade relative thereto, when in shaving position, and

Fig. 6 is a View in perspective of the blade carrier or'support.

Referring now to the drawings, which illustrate one embodiment of my invention, which has been selected for the purpose of this disclosure and in which like characters of reference are employed to designate similar parts throughout the several views, 7 indicates the blade carrier or support, which is stampedor pressed out of sheet metal, and which is formed with the usual guard 8. The guard 8, preferably, is of an 8 configuration, and is of the tooth or serrated type.

As will-be observed from Fig. 6 of the drawings, a portion of the blade carrier 7 intermediate of its ends is pressed out, as shown at 9, and is provided with an orifice 10, through which the threaded lug 11 of the clamping element '12 is adapted to project as shown in Fig. 4:.

The lug 11 is formed integral with a C16.

' pendent boss or protuberance 13, which may The blade 14.- which is of the so-called' wafer type is formed with the

cars

15 and 16 at each end thereof, to provide surfaces whereby the blade may be grasped between the thumb and fore-finger to facilitate positioning it on the clamping element .12 as hereinafter explained.

As will be seen from Fig. 2 of the drawingsthe major portion of the boss or pro-l tuberance 13 is spaced from the inner surface of the clamping element 12 as shown at 13, This space 13 is formed topermit of the location of the'blade 14 on the clamping member, so that the rear edge 14* of the blade, which lies inwardly of the rear edges I against the retaining flange-12, which forms the back of the clamping element 12.

hen the blade 14- is positioned on the of the ears 15 and..16 may abut or bear 7 clamping element 12, as described, the

clamping element is located on the blade carrier '1 the externally threaded lug 11- passing through the aperture 10 in the die pressed portion 9 of thelatt er member, The

cutting edge 'of the blade 1%, is then in functioning position relatively to the guard 8, and the clamping element and blade carrier are drawn together to imm'ovably clamp the blade in position therebetween. This is accomplished by means of the handle" 16 havin'ga diminished upperportion 17, the

end of which is provided with a recess 18 which is threaded as shown at 19." The threads, 1.9 are of the same gauge as and mesh with the external threads of the lug l1. Therefore, when the handle 16 is screwed up on the lug 11, the upper end of the handle will bear against the under-sun face of the depressed portion 9 of the blade carrier, causing the clamping ele'mentand blade carrier to approach each other and firmly grip the blade 1dE therebetween. This clamping action is obtained by the cooperation of the lug 11, the handle 16 and the depressed portion 9 of the blade carrier 7, which by reason of its formation is adapted to yield under the pressure exerted thereupon, by the upper end of the handle ld From the foregoing disclosure, it will be manifest that I have provided asimple device, which may be readily handled by the user and in which the parts may be kept thereon. v

by the simple expedient of disassembling and wiping or rinsing the parts, the disconclean and sanitary after the use of the razor, I

nection thereof affording access to. every possible for any foreign matter to remain W hile as before embodiment herein illustrated, it is obvious that various 7 changes in the detailsjof structure may be made, and that my-1nvenportion of their surfac es, so that it is inistated, I have' described' 7 my invention withireference to the specific v tion' may take other formstwithout dejoa'rtof the clamping element, an externally threaded lug carried by said thiekened 'p'ortion, a blade support provided with an aperture intermediate of its edgesto permit of the passage of said lug therethrough, and

a handle having a recess at its upper extremity threaded for engagement with said lug, whereby the handle maybe manipulated to produce pressure between said clamping element and blade supportto 'immovably hold a blade in cutting position.
