Toall whom it may concern 'Be' it known that I, AmmoMAa vrGtm; a subject of the King of Italy, and residing at Savona, Province of Ligu'ria, Ita1 ',have

invented certain new. and useful Improve According to the] invention within the.

usual handle provided with toothed blade guard is arranged so as to be axially movable a rectangular yoke traversing axially an opening which cuts the toothed blade guard in two alike syinni'etrical p'arts. The yoke carries rigidly or detachably connected with itithe means for fastening the blade so as to allow with the displacement of the blade guard against the blade the adapta- This yoke carries also means for sharpening the blade which include two rolls engaged with each other by toothed wheels and of which rolls the outer one is provided with means for fastening the blade, this sharpeningtaking place in simply passing a leather strip below the inner roll and in adhering the blade guard against the strip.

In the accompanying drawings in which like numbers of reference indicate the same or like parts,

Figures 1 and 2 show the safety razor in a first form of execution. Fig. 1 is a side View of the razor with the handle partially in a middle sectional View and Fig. 2 is a front View of the razor with the blade applied and with the leather strip inserted.

Figures 3, 4 and 5 show the razor in a second form of execution which differentiates from the first one in this that the blade is applied on the roll of the sharpening device by means of a blade carrier and rotated around one of its longer sides, the sharpening of the blade taking in this case place on both sides of the same edge and not along the two edges of the'same side of the blade as in the first form of execution.

Fig. 3 is a side view of the razor with the handle partially in a middle sectional view;

Fig.4 is a trout View of the razor with inserted leather strip;

Fig: 5 'is'a detail showingin three viewsthe detachablecro'ss piece 8.

F g. 61's detail showing 1n a side vie'v'v the bladej'carrier and'Fig. 7 is an end View According-to Figures 1 and 2 the safety razor provides a handle 1; with blade guard in two alikeypart's divided by an axial groove 2l With the handle 1 is connected by means of a pin 3" the screw 4 which can be rotated retating the but-tone.

Within the handle; 1 is arranged axially movable the rectangular yoke 6 arranged within thecutaand which penetrates by the tubular. shank 7 the handle constituting a nutmeinber for the screw 4. By rotating the button 5, the rectangular yoke 6 can be displaced within the cut 2. p

In Figures 1 and 2. the cross 'iece 8' is i tegral with the two sides 9' of the" yoke.

spending withthe usual three holes applied on the blade. Upon the sides 9 of the yoke are besides supported the ends of the two rolls 11 engaged at the outside of the yoke by toothed wheels 12 and constituting together With two other rolls rotatably sup ported on the sides 9 the sharpening device for the blade. The outer roll of the two rolls 11 carries three pins 13 corresponding with the holes applied on the blade. These pins are provided with-recesses 1 1 at its base allowing by grasping the button 15 a limited axial displacement and this in order to make the blade enter in these recesses. By applying the blade with its holes in correspondence with the pins 13 so as to assume the height of the recesses 14 and in displacing then the roll towards the right in grasping the button 15 the blade will be entered 111 these recesses. In passing then a leather strip below the inner roll 11 and exactly across the slot 16 and in giving then to-the razor a reciprocating motion on this leather strip conveniently appended at one end and kept by the hand at the other end the blade will be exposed to an oscillating motion and the edges sharpened with the proper inclination. I

In order to put the safety razor, after the sharpening operation, in'conditionto shave,

15 and displace the blade carrying roll 11-and then further. rotate theserew 4 so that the blade liberated from the recesses 14 pushed by the blade guard is placed u on the pins 10 of the cross piece 8 and t us f place the blade in the position required for shaving. a 7

According to Figures 3, 4c and 5 the cross piece 8 is detachably connected with the sides 9 of the yoke and this by means of pins 17 h applied upon the projections 17 of the cross piece,' which engage cuts 18 on'these sides 9. In connection with the safety razor of Figures 8 and 4 the blade for the sharpening operation is fastened upon a blade carrier consisting in a simple plate 20 supplied with circular edges 21 penetrating in the holes of the blade and presenting guides '22 oscillating around the pins 23 and adapted to be opened for the application of the blade on ihe carrier and to be closed afterwards. The

blade thus arranged upon the carrier is then applied upon the outer roll 11 in the way that the pins 24 are engaging theTecesses 25 of the carrier. In passing then the leather strip under the lower roll 11 and in conceding again to the tool a reciprocatingmovemention the strip, with the blade guard in touch with the strip, the blade will assume an oscillating motion and be sharpened on both sides of the same edge.

After the sharpening has taken place there will only have to be applied the detachable blade guard thereon and provided with an axial opening, an axially movable rectangular yoke situated in the axial opening and including an. outer crosspiece, means on the crosspiece for fastening a blade so as to allow in displacing the blade guard against theblade the adaptation'of the tool' for i shaving; a sharpening device'also carried-by the yoke and including two rolls, toothed; wheels engaging the rolls, and pins on the outer roll for engagement with-the rolls of the blade to be sharpened; and adapted for engagement with a. leatl1er sharpening strip which is passed under the innerroll for coactlng with the blade guard. c

2., A safety razor as claimed in claim 1:,

wherein the outer crosspiece is connected f With the yoke, a blade carrier for connecting Y vice so that the blade during the sharpening the blade with the roll of the sharpening deoperation is rotated around oneof its longer sides.

In testimony whereof I have signed my name to this specification. I
