--2 Claims.

This invention relates to means for reconditioning the cutting edges of razor blades.

Broadly, it is an object of my invention to provide a means .for reconditioning the cutting edges of razor blades in combination or in association with a safety razor.

More particularly, it is an objectof my invention to provide a movable plate between the blade and the cap of a razor so that by moving the plate laterally, the edges of the plate will realign theirregularities "of the cutting edges.

During the shaving process, .the hairs bend parts of the fine cutting edge outward so that the cutting edge loses its keenness Various means have been employed to sharpen the cutting edges,..such as honing on a flat or arcuate :stone, strapping, etc. I have .found that by moving a straight edge over the cutting edges .of the blade that the irregularities of the cutting edges created in shaving become easily straightened thus realigning the cutting edges and prolonging the shaving life of the blade.

A further object is to provide a combination cap and reconditioning means for a safety razor blade.

For a fuller understanding of the nature and objects of the invention, reference is had to the following detailed description, in connection with the accompanying drawing, in which:

Figure 1 is a top view of a safety razor with part of the cap and part of the plate for realigning the cutting edges broken away, the realigning plate being shown in shaving position.

Figure 2 is a side view thereof, part of the handle being broken away.

Figure 3 is an enlarged side view, partly in section, showing the realigning plate moved over one cutting edge, the opposite cutting edge being shown partly bent upward after use.

Figure 4 is a view taken along line 44 of Figure 3 showing the one cutting edge having been realigned while the opposite cutting edge shows the irregularities after shaving, part of the realigning plate being shown partly broken away.

Figure 5 is a greatly enlarged view of one corner of the realigning plate and razor blade showing the edge of the plate over the cutting edge of the blade, the corner of the plate having been broken away to show the irregularities of the cutting edge of the blade after shaving.

Figure 6 is a top view of a modified form of the invention comprising a combination cap and slideable member for realigning the cutting edges of a blade in shaving position, parts shown broken away.

'2 Figure 7 is the same view as Figure '6 except that the parts are shown in position for realigning the irregularities of the cutting edges of the blade. I Figure 8 is a section taken through line 8--8 of Fig-ure7.

Referring to the drawing, numeral [0 represents a cap having a concave inner surface 'H with a central projecting screw l2 well known in the razor art. An arcuate plate '13 of the same arc as the concave inner surface I I is posit'ioned beneath the cap 'I'D. ;'Plate 13 has a central opening 14 and other openings 15 and a pair or opposed projections or flanges it); the space between flanges ltbeing slightly wider than the length "of the cap Ill. The edges I! of cap H] act as guides for plate 13. The inner surfaces of theflanges ifislide against edges I! of the cap fljD when theplate I3 is manually moved laterally. Central screw i2 passes through opening 114 and the openings l5 permit any depending parts, such astlugs-"(riotshowm 'to pass through openings [5. Thefedge's I53 and I9 act as stops against screw l2 to limit the lateral,movement of plate F3. The "edges of openings 15 maybe used 'for the same pur ose, that is to act as stops against any projeotfons the bottom of the cap. The longitu'din'al-edges 20 of plate T3 are rounded and are 'p'erm'itt'ed'to slide over the cutting edges 2.! and 22 of the blade 23, since the size of opening it is large enough to permit edges 223 to pass over cutting edges 2| and 22.

A flexible razor blade 23 is placed between the plate l3 and the platform 25 as is well known in the art. Handle 25 is screwed onto screw l2 drawing the cap downward, flexing blade 23 and tightening the plate l3 and blade 23 between the cap I0 and platform 24, preventing movement of the blade and plate l3.

In order to use the plate I3 for reconditioning the cutting edges of the blade 23, the handle 25 is turned so that the cap l 9 is loosened sufliciently to permit the plate I3 to be moved laterally by the thumb and one finger pressing upon the opposed flanges l6. The edges 28 of plate 13 ride over the cutting edges 2| and 22 of the blade thus straightening the irregularities created in the cutting edges by shaving.

When the plate [3 is in the center of the razor as shown in Figures 1 and 2, and the handle 25 tightened, the razor is in condition for shaving.

Referrin to Figures 6, 7, and 8 which show a modification of the device shown in Figures 1 to 5 inclusive, numeral 26 is a movable plate with an arcuate inner surface 21 and having a rectangular opening 28 and a pair of opposed notches 29 communicating with opening 28. Projecting into opening 28 at each end are opposed pins or lugs 30. A bar 31 is centrally disposed within the rectangular opening 28 running parallel thereto. At each end of the bar 3| there is a notch 32 within which the pin 30 rides. A depending screw (not shown) projects from the center of the bar 3! and is adapted to pass through a central opening in the platform 33. A handle similar to 25 is adapted to screw onto the depending screw in order to tighten the bar 3|. A pin 34 projects from the center of the bar 3|. A slideable lockin member 35 having an opening 36 into which pin 34 passes and having depending projections 39 is adapted to slide longitudinally upon bar 3i. Lugs 31 projecting from the lower portion of bar 3! are adapted to fit within channel 38 of platform 33.

In order to use the device shown in Figures 6 to 8 inclusive, a double-edged blade is placed upon the arcuate platform 33 and the central screw depending from the movable bar 3i passed through the well known channel of the blade 23. The handle is then screwed onto the depending screw so that the blade 23 is flexed. The posi- The razor is now in position and the slideable lockin member moved to the left as shown in Figure 7 so that the depending projections 39 are aligned with the opposed notches 29. The edges 40-46 of the movable plate '26 are then grasped between the fingers and moved laterally from side to side so that the longitudinal edges 4! ride over the cutting edges 2| and 22 of the blade thus straightening the irregularities of the cutting edges due to shaving. During the lateral movement of plate 26 pins 30 move within the notches 32 of the bar 3| and projections 39 enter the notches 29. In order to again lock the razor in shaving position, plate 26 is moved centrally over platform 33, the locking member 35 is moved to the right as shown in Figure 6 and the handle is then tightened.

It is obvious that various changes and modifications may be made in the details of construction and arrangement of parts without departing from the general spirit of the invention,
