n SMITH, or ToNrnH, NEVADA,

l Razon ATTACHMENT.

applicati@ mea April 5, 1921, serial No. 458,667. Renewed January so, 1924.

To all whom t may conce/m: l

Be it known that l, FRANK E. SMITH, a citizen 'of the United States, residing at Tonopah7 county ofNye, and State of Nevada, have invented new and useful Im, provement's in Razor Attachments, of which l V the following is a specification.

i This invention relates to an attachmentfor razor blades. f v

" It is the principal object of the present invention to provide means adapted to be readil applied to the blades of safety or straig t razors whereby the skin in front of the cutting edge of the blade will be drawn smooth and taut as tlfe shaving operation is carried out.

The present invention' contemplates the use of a friction member mounted in connection with a razor blade anddisposed in front of the cutting edge thereof in a manner totrictionally engage the skin and tend to stretch the same.

The invention is illustrated by way of erample in the accompanying drawing, in which- Fig 1 is aview ,in perspective showing the application of the present invention to a safety razor..

Fig. 2 is a viewiin transverse section through the satety razor. showing the attacent applied thereto.

Fig. 3 is a fragmentary view in perspective showi the friction member.

. l is a view in transverse section show.. ing te application of the present invention to a straight razor blade.

Referring more particularly to the draw# ing, llll indicates a friction member. This device is rectangular in shape, forming al long narrow bar,vpref erably made of/rubf ber. Theoperating face of this bar carries a plurality `of diagonally disposed ribs' 11,

the ends of which arespaced a distance from leachother to permit lat er to pass therebetween while the faces these ribs frietionally en' 'ge the skin of the person being shaved. l e back' of the bar 10 is -formed with a longitudinal rib 12, upon the opposite sides of which grooves 13 occur. These grooves receive danges 14 ofa clamping clip 15, as shown in Fi 2 and d. The clip has an arcuate back plate 16 formed 'as a continuation of a clamping body. W'hen the device is used lor safety razors, this clampel body musfgbe designed to agree with the construction embodied within the razor, as

for e ixamp'le, -in the form of the razor shown in Flg. 1, 1t 1s necessary to provide two cen- 'tering openings 17, through the body of the clip and a central opening 18 'through which the clamplng screw of the razor extends. In

the form of the invention shown in Fig. 4,

it is only necessary to provide a yieldable clamp 19 adapted to pass around the back of a straight razor blade.

In operation of the present invention, application of the device to a razor is so made as to dispose the friction bar 10 in advance of the cutting edge of the blade.l This bar is so held as to press against the skin of the face while the blade is cutting, and'without interfering with the cutting action. This insures that the bulk of the lather on the face will be scraped away by the ribs and l that the faces of the ribs will frictionally engage the skin to draw it taut. This action will make it possible for the beard to be more readily 'shaved and that a very clean shave will be edected. lt will thus be seen that the present invention provides a simple attachment ior razors of all classes yby which a more thorough and clean shave may v 1.- An attachment for razor blades, com'- f prising a friction bar mounted upon the razor and disposed in advance of the cutting edge of the blade, said bar having spaced oppositely disposed diagonal vribs frictionally engaging the skin to pull the same tant as the razor moves, the spaces between the ribs forming passages for the lather.

2. An attachment for razors comprising a. clip adapted to be secured in conjunction with arazor blade, and a ./friction bar ot yieldable material mounted Within said clip in advance of the cutting edge of said blade.

`3. An attachment for razors comprising a plate adapted to be secured in conjunction with a razor blade and provided` with a` clip, a friction bar located in advance of the cutting edge of said blade and provided at the back with a rib held in said clip, and means Bld on the front face of said bar'whereby fricy tional contact with the skin may be effected.

4. The combination with a safety razor, a plate adapted to be secured to a razor frame attachment, clips at the outer end thereof, and a frictionbar disposed in advance of the cutting edge of the blade whereby said bar may rictionally engage the skin during the shaving'operation, said bar beingl provided at the back with a grooved rib arranged in and engaged by said clip.

5. The combination with a safety razor, a`

plate adapted to be secured to a razor frame attachment, clips at the outer end thereof, anda rubber friction bar carried by said clips and disposed in advance of the cutting edge of the blade whereby said bar may frictionally engage the skin during the shaving operation, the face of said bar being formed with diagonal ribs to increase its traction.
