This invention relates to stropping devices for attachment to safety razors.
The object of the present invention is toprovide a convenient form of such device which may be readily attached and detached from the safety razor.
According to my invention, the stropper comprises a cross-piece having members blade is held. Mounted in this cross pieceis a roller beneath which'the strop is passed. This roller gears with a spindle which carries members which open to receive the razorblade. These two members are adapted to be locked together by a clip in order to retain .the blade in position between them. 'The action of the device is that as the razor is moved in one direction along the strop, the roller will tend to be rotated by the strop and will cause the members carrying the blade to be forced down upon the strop to sharpen one side of the blade, and when the razor is moved in the other direction the members carrying the blade will be rotated over to the opposite position so as to sharpen the other side of the blade. 1
O The invention will nowbe described with the aid of the accompanying drawings,
wherein z-- Figure 1 is an end elevation of the stropper f will rotate the roller, but may still be drawn through when. the
. edtobe locked together by a clip'18 pivoted Figures 8 and 9 show two views of aclip for holding the blade in position.
Referring to the'drawings, the device con sists of a cross piece 1 having internally bent flanges 2 running the length of the cross piece which are adapted to fit between the guard member3 and vbacking member 4 of a. safety razor of the type shown. The end of the cross piece has brackets 5 turned upwards, While a roller 6 ismounted between the brackets 5, the reduced end forming the spindle of such roller at one end projecting through a bracket and havinga toothed wheel 7 fixedthereon, the strop 8 being ar ranged to pass between'the roller 6 and the top of the cross piecel and ride over rounded portions 9 (see Figures 1 and 4) The space between the roller and the cross piece'is such that the strop when drawn through this space roller cannot rotate any further. 1 f
The blade holder consists of two flat members 1-0 and l l, the member 10 being secured to a spindle l2rmounted to rotate in the brackets 5 and having on one end a toothed wheel 14 gearing with the toothed wheel 7.
The other member 11 is hingedfreely on the spindle 12 so that the two members 10 and 11 open out in a hinge-like manner. Pro ecting from the member 10 are a number of studs 15 adapted to pass through holes the studs 15 pass through the holes in the blade.
In order to retain-the blade of the razorfirmly grasped between the two members 10 and 11, such two members are adaptat'19' on the member 11. This clip 18 has anlarcuate opening 20 through which :projects a pin'21from the central stud 15. The
head of the pin is larger than the arcuate slot 20,but such slot ends in an opening. 22
slightly larger than the head of the pin.
\Vhen the blade of the razor is inserted in position between the two members 10 and 11,
the clip 18 by being moved over to the posi- 5 tion shown in Figures 5 and 8, will retain the two members and 11 firmly together and the blade in a rigid position. When, however, it is desired to remove the blade, the clip 18 is moved to the position shown in Figure 9, and the two members may then be opened and the blade removed.
In operation, the strop is passed beneath the roller 6 and the cross piece 1 and by moving the razor in the direct-ion oft-he arrow in Figure 1, the members 10 andll carrying the blade will be forced by theaction of the roller 6 on to the strop as shown, and when the handle is moved in the other direction, the members 10 and 11 will then anove over to the position shown in dotted lines in Figure 1, thus sharpening the other side of the razor blade.
To remove the stropping device, the handle of the razor is simply unscrewed and the cross piece will slide out from between the guard member and the backing member.
lVhat I claim is 1. A stropping device for attachment to safety razors having guard and backing members, comprising a cross piece having members to engage between the said guard and backing members, bearing brackets projecting upwardly from the cross piece adjacent the ends thereof, a roller pivoted in said brackets and beneath which the strop is passed internally of the bearing brackets, a spindle also mounted between the said hearing brackets, and adapted to be rotated by the said rollers, and additional members on said spindle for carrying the razor blade and adapted to bear on one side of the strop when the razor is moved in one direction, and to then bear on the other side when the razor is moved in the other direction, the said member of the cross piece comprising internally bent longitudinal flanges adapted to be inserted in endwise direction between the longitudinal extremities of the said guard and backing members.
2. A stropping device for attachment to safety razors having guard and backing members, comprising a cross piece having members to engage between the said guard and backing members, bearing brackets project- 55 ing upwardly from the cross pieces adjacent the ends thereof, a roller pivoted in said brackets and beneath which the strop is passed internally of the bearing brackets, a
spindle also mounted between the said bear- 60 ing brackets, and adapted to be rotated by the said rollers, members on the spindle for carrying the razor blade and adapted to bear first on one side or the strop when the razor is moved in one direction, and then 65 to bear on' the other side when the razor is
