Figure 12 is a'sectional detail on an enlarged scale taken substantially on the lines- I2-l2 as shown in Figure 5. Referring to the drawings, the holder generally designated It) includes a head I i and a guard member l2 secured together by means of a pivotal connection designated l3. 'A magazine M is receivedwithin a pocket [5 defined by the head II and guard l2, and this magazine carries a flexible-1 ribbon blade 16 of considerable length. One edge of the blade is sharpened as indicated at ll. The head ll inclines forwardly at an acute. angle from its vertical neck portion 8 and is secured by means of a suitable connection E8 to the vertically extending handle I9.

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 cover2 I and which are later deformed as indicated at 24 to prevent disassembly (see Figure 10).

A horizontalslot 25 provided in the base 29 separates the main portion of the base 29 from thehorizontal 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 upper surface 29 of the bridge 26 and under the. flange 28. The ribbon blade It extends from a supply, coil positioned within a recess 3! provided in the base 20. The other end of the blade l6 may be received in a mounting slot 32 provided in a take-up drum or spool 33 positioned The ribbon blade It extends across within the recess 34. The recess 34 is also formed in the base 26 and is positioned symmetrically with the recess 3| with respect to 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 H and projects through an aperture 38 provided therein. A flange 39 on the knob 31 prevents disassembly with respect to the head Th size of the aperture 38 is somewhat larger than the hub 46. 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 26 and cover 2| respectively. It will be recognized that the knob 31 need not be attached to the head I l 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 l9. Rotation of the knob 31 serves to wind the ribbon blade l6 onto the reel 33 and hence cause the blade to move across the bridge 26 and unspool from the reel 36.

Rounded surfaces 42 and 43 are provided on the base 26 and are contacted by the ribbon blade It at each end of the bridge 26. 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 H of the ribbon blade I6. As shown,

in Figure 4, the guide flanges merge at their lower ends into the end walls 46 of the base and terminate at their upper ends near the intersections 4 secure additional stiffness. Recesses 65 in the head 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 l6. As shown in the drawings, this means includes a plurality of ratchet teeth 54 formed on the side face of the reel 33, together with a pawl element 55 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 suflicient 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 of the curved surfaces 42 and 43 with the upper plane surface 29 of the bridge 26. The sharpened edge ll 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 in cludes 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 H, as is clearly shown in Figure 11. Thus, tensioning of the ribbon blade l6 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 3| 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 l6 into contact with the cover 2|. The sharpened edge 11 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 H, 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 T be provided with a pair of annular ridges 53 to 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 I6 over the curved surface 42, provides sufiicient frictional resistance to maintain proper tension on the blade as it reaches the bridge 26. The ratchet device 54, 55 prevents unwinding of the blade at the other end of the bridge.

Theribbon blade l6 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 66 is provided on the other side of the base communicating with the recess 34. Nonmetallic sealing elements 6| may be provided adjacentthe slots 58 and 60 in a position to contact the ribbon blade l6. These sealing elements 6| assist in excluding entrance of water or foreign matter into the recesses 3| and 34.

Means are provided for maintaining the pivoted guard member in closed position and for urging the magazine |4 into engagement under the lip 66 provided on the head I As shown in the drawings, this means includes a cam member 61 pivotally mounted with respect to the handle l9 and head H by means of the pin 68. The nose 69 of the cam is adapted to abut the lower end 76 of the guard |2. A slot"|| in the head loosely receives the tab 9 so that the guard may have limited universal swiveling movement and may also move longitudinally in a direction par allel to the head The shelf 12 on the guard |2 supports the magazine l4 along its lower edge so that upward movement of the guard |2 serves to clamp the magazine |4 between the lip 66 and shelf 12. Since the cover or guard |2 is free to swivel with respect to the head H, the magazine M is aligned by the lip 66 and not by the shelf 12. This clamping action servesto hold the magazine |4 securely in place and further acts to provide additional stiffness for the flange 28 which overlies the ribbon blade |6. Under this clamping force the flange 28 deflects slightly so that the ribbon blade |6 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'slotsfi, 21 and provided in the base cover Zlandhead H- respectively.

The cam 61- may-berotatedto an-inoperative position as shownby the dotted lines in Figure 1 to permit the guard I2 to be swung 'to open position as indicated by the dotted li'nesin Figure-2; The magazine M may'then be installed by placing its lower'edge on theshelf l2 and then swing"- ing' the guard 52' toward closed'positionsothat' the magazine M remains in the pocket 15'; As the guard is swung toward" closed position the noncircular' projection 36 enters-the noncircular' opening in the take-up spool orreel 33; The relatively loose fit of the knob member Win the head" opening 38 facilitates thisoperatiorr;

The flange 28 on the magazine cover 21 underlies the lip 66 on the head H. The cam; GT is swung to its'op'erative position so that the nose: 69 engages the lower edge 10 of the guard l2 and moves the guard and magazine upwardly. to

clamp the magazine between. the lip 66 and shelf '12. The razor isthen ready for use.

When the exposed or active portion of the sharpened edge I! becomes dulled throughuse, the knob 37 is rotated to bring, afresh portion into position onthe bridge 25. A very large number of active lengths are thus provided on the relatively long ribbon 16. When the blade [6 has been completely used up, that is, wound on the take-up reel 33, the holder I0 is opened and the used magazine l4 withdrawn. A new magazine is then inserted into the pocket ['5 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 guardedandishielded. against contact, except for theexposed or active length extending along the bridge 26 between the flanges 44 and 45. If desired, a portion of the blade l6 which is initially exposed may have its cutting edge l1 dulled to further insure against accidental injury when installing the magazine l4 into the holder Ill. The magazine I4 is automatically self-aligned on the razor head H by reason of its linear contact with the underside of the lip 66 and the point contact of the supporting guard i2 and swinging cam 61. When once installed the knob 31 is turned to bring the sharpened portion of the blade into operative position.
