25 Claims. (01. 30-40) This invention relates to safety razors and is particularly directed toward a novel form employing a sharpened ribbon blade of considerable length which may be unspooled from a magazine to present successive unused portions as desired.

This invention relates to improvements over the device shown in the copending application of George Douglas Jones for Razor, filed July 6, 1948, Serial No. 37,100.

The principal object of this invention i to provide a. new and improved form of shaving razor.

Another object is to provide a novel form of disposable blade magazine.

Another object is to provide a new and improved form of holder for supporting a disposable magazine.

Another object is to provide a holder for a blade magazine, the holder including a head inclined forwardly from a supporting upright handle, and a guard pivotally associated with the head and cooperating therewith to define a magazine receiving pocket.

Another object is to provide a novel form of shaving razor using a ribbon blade, and which is adapted for economical manufacture on a quantity basis.

A further object is to provide a shaving razor utilizing a ribbon blade and constructed in a manner so that the sharpened edge of the blade is kept out of contact with parts of the razor in order to maintain maximum sharpness.

Other and more detailed objects and advantages will appear hereinafter.

Referring to the drawings, the holder generally designated l0 includes a head Ii and a guard member l2 secured together by means of a pivotal connection designated l3. A magazine H is received within a pocket l5 defined by the head II and guard l2, and this magazine carries a flexible ribbon blade iii of considerable length. One edge of the blade is sharpened as indicated at H. The head ll inclines forwardly at an acute angle from the vertical and is secured by means of a suitable connection l8 to the vertically extending handle IS.

The magazine i4 is generally rectangular in shape and is relatively thin compared to its length and width.. The lower edges of the rectangle may be rounded as indicated in the drawings. The magazine may include a base 20 and a cover 2| secured by any convenient means such as, for

example, by means of projecting pin elements 22 on the base 20 which extend through apertures 23 in the cover 2| and which are later deformed as indicatedat 24 to prevent disassembly (see Figure 10).

A horizontal slot 25 provided in the base 20 separates the main portion of the base 20 from the horizontal bridge 26. A slot 21 in the cover 2| is aligned with the base slot 25, and a forwardly extending flange 28 on the cover 2! overlies the bridge 26. The ribbon blade 16 extends across the upper-surface 29 of the bridge 26 and under the flange 28. The ribbon blade l6 extends from a supply coil 30 positioned within a recess 3| provided in the base 20. The other end of the blade 16 may be received in a mounting slot 32 provided in a take-up drum or spool 33 positioned within the recess 34. The recess 34 is also formed .in the base 20 and is positioned symmetrically with the recess 3| with respect to 1 the bridge 26.

A noncircular opening 35 is provided in the reel 33, and a cooperating noncircular projection 36 on the knob 31 is carried on the head II and projects through an aperture 38 provided therein. A flange 39 on the knob 31 prevents disassembly with respect to the head I I. The size of the aper- 3 ture 38 is somewhat larger thanthe hub 40. The cylindrical surface 4| of the knob may be roughened or serrated as shown. The reel 33 is provided with outwardly extending'hub portions 62 which are received within the axially aligned openings 63 and 64 provided in the base 20 and cover 2| respectively. It will be recognized that the knob 31 need not be attached to the head II but may comprise a separate and distinct part if desired, and indeed may be shaped to be received within a convenient recess provided on the handle l8. Rotation of the knob 3'! serves to wind the ribbon blade l6 onto the reel 33 and hence cause the blade to move across the bridge 25 and unspool from the reel 39.

Rounded surfaces

42 and 43 are provided on the base 20 and are contacted by the ribbon blade l5 at each end of the bridge 25.

Guide flanges

44 and 45. extend along the sides of the

curved surfaces

42 and 43 respectively, and these guide flanges are positioned adjacent the sharpened edge ll of the ribbon blade l5. As shown in Figure 4, the guide flanges merge at their lower ends into the end walls 45 of the base 20 and terminate at their upper ends near the intersections of the

curved surfaces

42 and 43 with the upper plane surface 29 of the bridge 26. The sharpened edge I! of the blade is kept away from contact with the

flanges

44 and 45 in order to maintain the blade at its maximum sharpness and to avoid the possibility of dulling before use.

Means are provided for maintaining the heel edge 41 against the inner surface 48 of the cover 2|, and as shown in the drawings this means includes the slanting of the surfaces of the curved ends 42 and 43 so that the heel end 41 of the blade l6 travels over a shorter arc than the portion of the blade adjacent the sharpened edge II, as is clearly shown in Fig. 11. Thus, tensioning of the ribbon blade l5 between the substantially conically

curved portions

42 and 43 causes the blade to move toward the low side and thereby move the heel 41 against the surface 48.

As a further aid in positioning the sharpened edge so that it will not be contacted prior to use during shaving, and in this way to insure its maximum sharpness, the recess'3l is provided with a tapering wall 49 which is larger on the diameter adjacent the cover 2| than on the inner diameter at the bottom of the recess. The angle of inclination of the wall 49 and the inclination of the curved surface 42 have each been exaggerated in Figures 9 and 11 of the drawings for clarity of illustration. The effect of this tapered bore is to cause the individual loops of the coil to expand to the largest diameter and hence move the heel edge 41 of the continuous ribbon blade I5 into contact with the cover 2|.

reel 33, together with a pawl element for engaging the teeth 54. This pawl element 55 may be formed as an integral part of the cover 2| and may be separated by a stamping operation from the remainder of the cover along the radial line 56 and intersecting circumferential line 51. The pawl 55 is deformed inwardly as shown in Figure 12, and its integral connection with the cover 2| provides sufiicient resilience to permit the pawl to deflect outwardly and allow the ratchet teeth 54 to pass by in one direction. Reverse rotation of the reel 33 is prevented. From this description it will be observed that a ratchet and pawl device has been provided for preventing a reverse rotation of the reel 33, which device requires no separate or additional parts and which may be manufactured economically on a quantity basis.

The tendency of the coil loops to expand within the recess 3|, together with the friction of the blade |6 over the curved surface 42, provides.

sufficient frictional resistance to maintain proper tension on the blade as it reaches the bridge 25. The

ratchet device

54, 55 prevents unwinding of the blade at the other end of the bridge.

The ribbon blade I6 extends from the coil 30 through a slot 58 leading from the recess 3| to the curved surface 42, the outer end of the slot being defined by the upper edge 59 of the end wall 46. A similar slot 60 .is provided on the other side of the base communicating with the recess 34. Nonmetallic sealing elements 6| may be provided adjacent the slots 58 and '60 in a position to contact the ribbon blade l6. These sealing elements 6| assist in excluding entrance of wfiater or foreign matter into the recesses 3| and 3 Means are provided for maintaining the pivoted guard member in closed position and for urging the magazine l4 into engagement under the lip 56 provided on the head As shown in the drawings, this means includes a cam member 61 pivotally mounted with respect to the handle The sharpened edge I1 is in this way held out of contact with the bottom 50 of the recess 3|. An annular nonmetallic washer 5| may be mounted in the bottom of the recess 3| if desired as a further protection for the sharpened edge l1, and this washer 5| may have a central aperture to receive the centering boss 52 (see Figure 7). The cover may comprise a metal stamping, if desired, and be provided with a pair of annular ridges 53 to secure additional stiffness. Recesses 55 in the head ll afford clearance for the annular ridges 53.

Ratchet means are provided to prevent unspooling of the drum 33 and thereby maintain tension on the ribbon blade l5. As shown in the drawings, this means includes a plurality of ratchet teeth 54 formed on the side face of the I9 and head II by means ofthe pin 68. The nose 59 of the cam is adapted to abut the lower end 10 of the guard i2. A slot II in the guard member |2 receives the pivot pin I3 so that the guard may move in a. direction parallel to the head The shelf 12 on the guard l2 supports the magazine l4 along its lower edge so that upward movement of the guard l2 serves to clamp the magazine I4 between the lip 66 and shelf 12. This action serves to hold the magazine |4 securely in place and further acts to provide additional stiffness for the flange 28 which overlies the ribbon blade l6. Under this clamping force the flange 28 deflects slightly so that the ribbon blade I5 is held tightly on the bridge seat 29. The upper edge of the guard I2 is provided with the usual comb teeth 13. As shown clearly in Figures 9 and 10, the bridge 26 is cut away on its under side to provide an entrance opening 14 leading into communication with the horizontal aligned

slots

25, 21 and 15 provided in the base 20, cover 2| and head M respectively.

The cam 51 may be rotated to an inoperative position as shown by the dotted lines in Figure l to permit the guard |2 to be swung to open position as indicated by the dotted lines in Figure 2. The magazine l4 may then be installed by placing its lower edge on the shelf 12 and then swinging the guard I2 toward closed position so that the magazine I4 remains in the pocket l5. As the guard is swung toward closed position the noncircularprojection 36 enters the noncircular opening 35 in the take-up spool or reel 33. The

relatively loose flt of the knob member 31 in the head opening 38 facilitates this operation.

e flange 28 on the magazine cover 2| underlies the lip 66 on the head H. The cam 61 is sw'ung to its operative position so that the nose Cl engages the lower edge 10 of the guard I2 and moves the guard and magazine upwardly to clamp the magazine between the lip 66 and shelf 12. The razor is then ready for use. 7

The inclination of the head H with respect to the handle l9, together with the rectangular flat shape of the head H is particularly advantageous, since it provides the user of the razor with fingertip control. The razor handle 19 extends into the palm of the hand, while the index finger and middle flnger of the user contact the backside of the head II and the flat face of the knob 31. The relatively narrow upper edge of the razor holder l under this fingertip control affords a highly advantageous structure for shaving in places difllcult of access such as under the nose and adjacent a moustache. The forwardly inclined head conforms to the natural angle of the fingers of the hand and enables the razor to be guided with maximum benefit. One of the flngers of the user may rest on the flat side of the knob 31. If desired, a dummy knob may be provided on the back side of the head ii to balance the design and thus provide knobs for both fingers.

When the exposed or active portion of the sharpened edge I! becomes dulled through use, the knob 31 is rotated to bring a fresh portion into position on the bridge 26. A very large number of active lengths are thus provided on the relatively long ribbon It. When the blade It has been completely used up, that is, wound on the take-up reel 33, the holder I0 is opened and the used magazine It withdrawn. A new magazine is then inserted into the pocket It and the device is again ready for use. The new magazine may be handled without using great care since the cutting edge I! is well guarded and shielded against contact, except for the exposed or active length extending along the bridge 26 between the flanges N and 45. If desired, a portion of the blade it which is initially exposed may have its cutting edge I! dulled to further insure against accidental injury when installing the magazine It into the holder l0. When once installed the knob 31 is turned to bring the sharpened portion of the blade into operative position. v

The magazine It may be used without the holder in for shaving if desired, since the flange serves to confine the blade I6 on the bridge surface 29. The blade is not held as rigidly since the lip 65' is not present to contribute to the still.- ening effect, but nevertheless, the magazine may be held between the fingers of the user and a satisfactory shave may be obtained without em ploying a holder or handle.
