Baumgardner, Bayside, N. Y., assignors to Warner-Lambert Pharmaceutical Company, a corporation of Delaware Application January 16, 1953, Serial No. 331,620

Claims. (Cl. -40) This invention relates to safety razors, and, in specific aspects of preferred embodiments thereof, is particularly directed to a novel razor and to a novel ribbon blade magazine therefor, wherein the blade presents a sharpened edge, such blade being of sufficient length so that it may be unspooled from the magazine to present a sub stantial number of successive unused portions as desired.

In specific embodiments of the razor it represents improvements on the razor shown and claimed in the patent to Jones et al. No. 2,492,292, December 27, 1949.

The convenience and. safety of storage and carrying of a substantial length of sharpened blade, and the speed with which the operative portion of such blade may be changed, have long made the ribbon type of safety razor theoretically attractive. Various practical difficulties,

however, including the lack of a razor which is convena ient, accurate, and durable, have kept such razor from wide commercialization. Previous razors of this type, having a coil containing magazine in the head thereof, have been cumbersome, heavy, hard to load and to unload, and have been particularly liable to damage during normal carrying and handling. At their best such razors were inaccurate in their blade positioning, and naturally were prone to becoming much more inaccurate after the razor had been used for some time andhad been subjected to the normal springing of the parts upon being loaded and unloaded. The normal impacts upon the razor occurring during use, such as its being dropped upon lavatories and bathroom shelves, have aggravated the above difiiculties.

It is accordingly among the objects of the present invention to provide a safety razor, particularly of the ribbon blade type, which is strong and durable, and which will position the blade accurately during long periods of use.

A further object of the invention lies in the design of a razor of the recited type in which the magazine containing and locating means, including the lip engaging the top of the magazine and the comb positioned in front of the blade, are presented in a strong integral member.

Yet another object of the invention resides in the provision of a magazine type of razor which may be quickly and accurately loaded and which inherently locates the active portion of the blade in the correct shaving position.

A still further object of the invention resides in the provision, in a razor of the type described, of a magazine and blade holding and locating means which positions such magazine and blade accurately upon the initial loading as by dropping of the magazine into such means, the magazine pressing means not being relied upon for such initial positioning, such means, however, constantly acting to press the magazine still more firmly into the seat or pocket.

Another object of the invention resides in the provision in a razor of the type described of a means for pressing the magazine into the seat, such means acting symmetri- 2,729,885 Patented Jan. 10, 1956 cally on the magazine and in such direction as to thrust the magazine into the seat.

In the specific embodiment of the razor shown, a feature of the invention resides in the design of the blade traversing means so that such means does not interfere with the initial accurate positioning of the magazine in the magazine holding element, and, in the preferred orientation of the driving means for the blade traversing reel, so that such blade traversing means does not interfere with the positioning of the magazine during normal loading and closing of the razor.

A still further object of the invention lies in the pro vision of an improved ribbon blade containing magazine, the magazine being of such design in its preferred embodiment that the sharpened edge of the blade in the supply coil is prevented from contact with any fixed part of the razor, and further that there is no danger of escape of the trailing end of the blade from the magazine.

The above and further objects of the invention will be more readily apparent upon consideration of the accompanying drawings, forming a part of the specification, in which:

Fig. 12 is a view in section through the loaded magazine, the section being taken along the line 1212 in Fig. 10, the supply and take-up coils of the ribbon blade being shown with the supply coil of ribbon blade somewhat more than half exhausted; and

Fig. 13 is a fragmentary view in section at the upper corner of the magazine retaining and locating element at the head of the razor, the section being taken along the line 13-43 in Fig. 1, the only portions of the magazine shown being the upper flange and the magazine locating ears.

As shown, the razor includes a razor head, generally designated 2, and a handle 4, centrally positioned on the bottom thereof, which depends from such head. The main body of such razor head, designated 6, is fixedly positioned on the handle 4 at the convenient shaving angle shown in Figs. 5 and 6, such main body 6 including the broad surfaced rear plate'8, on the bottom and sides of which is disposed the forwardly projecting flange 10. The plate 3 and the flange'lt) form a space which is partially coextensive with, and forms an extension of, the magazine receiving and locating pocket in the magazine holding element of the razor head. The side portions of flange 10 are continued abovethe top edge 14 of plate 8 to form the parallel spaced ears 12.

Body 6 of the head is retained on handle 4 by means of the channel shaped structures 16 on the bottom of such body, such channel being receivedin the longitudinal passage 18. in the top of handle 4. The handle retaining structure and the manner of mounting the handle on the razor will be described more particularly hereinafter. V

'Pivotally mountedaon the main body 6 of the razor head, by means of the pivot pins 20 extending through the cars 12 thereof, is the integral magazine retaining and locating element 22. Means 22 has a broad plate, member 24, which, as shown in Figs. 51 and 6, is located generally parallel to the member 8- when the razor is in closed, operative condition. At the top of member 24 there is provided the rearwardly extending transverse flange 26, whichfunctions as a depth gauge and guide for the blade and.whichI is designated a comb, even though in the embodiment shown it is not serrated. The flange 26 is cut away to a slight degree at the ends 28 thereof as indicated inFig. 3. Rearwardly projecting from the member 22,

adja'centthe top thereof, are the spaced parallel flange 7 members 30, which form the ends of the magazine receivingand positioning pocket on element 22. Such pocket is completed by the rear, magazine retaining, wall 32 which connects the rear ends of the end walls 30 and which lies parallel to theinner surface of the broad plate member 24 of element 22. The pocket thus formed between the members'24, 30, and 32 is of such length and thickness as snugly and accurately to receive the ribbon blade containirig magazine 34, the rear wall forming member 32 being of such height, as for example a third of the height of the magazine, as stably to retain the magazine in the pocket, even with the element 22 in the open position shown in Fig. 4.

The top of such magazine retaining pocket in element 22, when the'razor is in normal shaving position, or the bottom of such pocket as is shown in Fig. 4, is provided by the forwardly and somewhat downwardly (Figs. 5 and 6) extending flange or lip 36 on the top of the rear wall forming member 32 of element 22, lip 36 functioning as a guard. Lip 36 extends substantially wholly across the member 32 and extends forwardly across the pocket for a substantial distance, as shown in Figs. 5 and 6, so as to form a magazine locating seat and blade pressing means, in the manner to. be described. In the preferred specific embodiment shown, although the invention is not limited thereto, the bottom surface of lip 36 inclines forwardly and downwardly at an angle of 5 with respect to the hori zontal. The forward edge of the lip 36 and the rear edge of the comb 26 thus forma transverse, blade exposing, slot or gap 38 (Fig. 4) between them, the rear edge of such slot being elevated above the forward edge of such slot. As shown in the drawings, and as will be described more particularly hereinafter, the. upper portion of the ribbon blade magazine is so positioned in the pocket in element 22 thatits upper, blade exposing portion is presented in shaving relationship within the thus described slot 38.

The upper part of rear wall 32 of member 22 of the razor head is provided with three longitudinally disposed openings 40 therethrough as shown, such openings being vertically aligned with the two openings 42 through the upper portion of front wall member 24 of element 22 and,

in the embodiment shown, being generally aligned with the three openings 44; through the corresponding portion of the magazine 34.

Such openings

40, 42, and 44 are provided to facilitate flushing of the. razor after use. Openings 46 in the bottom of flange 10, one on each side of handle 4, further aid in the flushing of the razor and magazine and the drainage of water therefrom. The upper portion of member '24 is provided at the ends thereof with vertical end portions 48, and with a central vertical strut member 59, which attach the comb 26 to the main body of member 24. Magazine holding and positioning element 22 is, as described, pivoted into position about the pins 20 which extend through the ears 12 and the end walls 30 of the pocket forming element, as most clearly shown in Fig. 4. The upper edge 14 of the rear plate 8 is so located as to holdmember 22 stably in open position with such member at a marked angle to the member 8, as shown in Fig. 4. 7

It will be appreciated from the above that the blade providing magazine is initially positioned in the razor in a pocket provided in member 22 which accurately and stably holds it in operative position relative to the transverse blade exposing slot or gap 38 in such member 22. Member 22 is of integral construction, and is so designed that it is strong. and durable. The blade exposingslot 38 is therefore of constant dimensions both as to its width and also as to the height which its rear edge lies above its forward edge. As a consequence of such construc tion the magazine holding and blade locating member of the razor is. initially accurate and remains so in spite of long hard usage.

The magazine 34 of the razor, shown in its preferred embodiment in Figs. 7, 8, 10, 11, and 1 2, has a front housing member 52 and a rear housing member 54. Member 52, which is preferably made of sheet metal, has pressed thereinto, projecting toward the reader in Figs. '7 and 10, the blade supply coil cavity 56, the take-up blade coilcavity 52%, and the bridge structure 66 connecting such cavities. The remaining portion of member 52, that is,

that above and below the cavities and bridge and genhaving the sharpened edge 69, is disposed'in the cavity 56, the magazine being shown in Fig. 10 in that condition in which the supply coil of ribbon blade is full. The

ribbon blade 68 is led from coil 66 up over the first curved guide member 7am housing element 52, thence across the straight blade supporting bridge 72, then down the second curved guide 74 on the housing member 52, and finally into the take-up coilcavity 58 wherein it is coiled upon the take-up reel 76. The

members

70, 72, and 74 are in the form of flanges on the edge of member 52, such flanges facing the reader in Fig. 10. The curved guides 79 and 74 are of greater width than the blade 68 throughout the major portion of their length, as indicated in Fig. 11, but become gradually narrower in the zones '71 to join bridge 72. The sharpened edge 69 and a portion ofthe blade to the rear thereof in the upper straight operative portion of the blade lying upon the bridge "72 extends forwardly of the bridge.

The rear housing member 54 is, as previously indicated, generally in the form of a flat plate, having an external configuration generally conforming to but slightly larger than that of the front housing member 52. Member 54 has pressed outwardly toward the rear thereof the shallowcorrugation 78, the longitudinal central portions of which are straight and the end portions of which are arcuate, as more cleariy shown in Fig. 8.

Suchcorrugation serves not only to strengthenthe rear.

housingniei nber, but also functions as a magazine positioning. element, as will be clear hereinafter. Member 54 has an opening 80 therein axially aligned with the opening 82 in the front housing member, and an opening 84 axially aligned with the opening 86 in the front housing member 52.

Openings

82, 80, and those between the spoke members 64 at the supply coil cavity serve to facilitate flushing of the magazine. Openings 84 and 86 in the rear and front housing members serve as bearings receiving the outer ends of the hub 88 of the take-up reel 76, as shownin Fig. 12.

Housing members

52 and 54 are connected by means of the tabs 90 at the lower corners of the member 52, as it is shown in Fig. 12, such tabs being bent upwardly and over the edges of the front housing member 52, being received within the shallow notches 92 cut therein. At the top of the magazine the housing parts are retained together by means of the tabs 94 lanced from the outer ends of the outer longitudinal openings 44 in member 54, such tabs extending through the corresponding openings 44 in the front member of the housing and being bent outwardly over the edges thereof, as shown in Figs. 7 and 10.

As indicated more clearly in Fig. 11, the rear housing member 54 has on the top thereof the forwardly projecting and somewhat downwardly inclined top flange 96 which overlies the operative straight portion of the blade 68 on bridge 72, flange 96 being somewhat shallower than the bridge 72, the flange and the bridge converging so that the flange 96 contacts the blade most strongly adjacent the outer edge of the flange. The angle at which flange 96 inclines downwardly with respect to the horizontal is indicated by the character B in Fig. 11. Housing member 54 is further provided with two diametrically disposed detents 98 on opposite sides of the opening 84, such detents cooperating with ratchet teeth 100 on the lower surface of the web of take-up reel 76 to prevent rotation of such reel in other than the take-up direction. The reel 76 has a rim 102 having a width such that it fits fairly accurately between the inner surfaces of the opposing side walls of the housing. The hub 88 of the take-up reel has a splined passage 104 therethrough for the reception of the stem of the winding knob on the razor, to be described. The front housing member 52 of the magazine is provided centrally at the bottom thereof with a magazine locating cam surface 106 in the form of a pressed up member inclining upwardly and forwardly from the lower edge of the magazine.

As shown in Figs. 7, 8, and the rear housing member is substantially extended beyond the front housing member at its upper corners, terminating in a pair of symmetrically located ears or tabs 75 lying in the plane of member 54. Members 75 are designed to be received in pockets 77 in the upper corners of the magazine retaining and locating element 22 at the juncture of rear wall 32 and lip 36 thereof. The pockets 77 are of sulficient depth to receive the full depth of ears 75 when flange 96 of the magazine is engaged with the lip and rear wall of element 22 in the manner shown in Fig. 5, and at least slightly exceed the horizontal length of the ears. The pocket 77 has a forward wall 79 which inclines forwardly and downwardly at a sharp angle, such as 45 as shown, each wall 79 engaging the upper end of its corresponding ear 75 in the manner shown in Fig. 13 when the magazine is mounted in operative position in the razor head. As a consequence of such construction the magazine is positively and accurately located at the top in element 22.

In the loading and assembly of the magazine an appropriate length of the ribbon blade is formed into the coil 66 with the inner end of the coil bent to lie substantially diametrically of the coil, as shown at 83 in Figs. 10 and 12. Part 83 serves as a partial core for the coil and a guide therefor in cavity 56. The coil is then disposed in cavity 56 in the member 52 in the manner shown, the leading edge of the blade being brought out and around the

guide members

70, 72, and 74 in that order.

The take-up reel 76 is then inserted in the take-up cavity following which the leading end 68' of the ribbon blade is inserted into the take-up cavity 58 in the manner shown in Fig. 10. The reel is made automatically to be connected to the blade upon turning of the reel in the take-up direction by providing two diametrically cutout or relieved portions 108 in the rim of the reel. Somewhat rearwardly of the leading edge of the blade there is punched rearwardly therefrom the generally L-shaped tang 110, the free end of which is directed inwardly of the take-up cavity 58. When the leading edge of the blade is thrust into the take-up cavity a suflicient distance, the tang 110 will automatically snap into the opening 108 opposite it, so that upon turning of the reel in the counter-clockwise direction in Fig. 10 the blade will become permanently affixed to the reel. Following this the rear housing member 54 is placed on top of the front housing member, blade coil, and take-up reel assembly. The tabs and 94 may then be bent over to fasten the housing parts firmly together.

The side walls of the blade supply coil containing cavity 56 are of such angularity with respect to the axis of the cavity, the

curved guides

70 and 74 are of such radius of curvature and have such angularity with respect to such axis, and the bridge 72 is of such angu-' lari ty with respect to such axis, that the stresses imposed upon the blade 68 upon storage in coiled condition in cavity 56, upon being fed around the coil, and upon being eventually fed out of the cavity 56 around guides 70, 72, and 74, is substantially minimized. The inner faces of the side walls 112 of the cavity 56 have an angularity with respect to the axis of the cavity which would result from the formation of the cavity by thrusting a die in the form of a frustum of a cone having an apex angle of 6 into the sheet stock to form member 52 generally in a direction toward the reader in Fig. l0 but with the axis of the die tipped to the right 1 from a line normal to the original plane of the stock, which is also the direction normal to the main extent of the magazine. As a result, the side wall 112 of cavity 56 at the points where it is cut by the line 11--11 in Fig. 10 lies at angles C and D, above and below the axis of the cavity, respectively, both angles C and D being 3" in the preferred embodiment. As a result of such tipping of the axis of the cavity 56, the side wall 112 at the point where it is cut by the line 12-12 lies at an angle E with respect to the axis of the cavity, such angle being on the order of 3%. At the point on the side wall 112 of the cavity 56 lying along the line 00, approximately where the blade 68 leaves the cavity, the side wall makes an angle of 4 with respect to the axis of the cavity.

Throughout its extent the side wall of the cavity 56 has a greater diameter at its inner end adjacent the rear housing member 54 than it does at its outer end adjacent the front housing member 52, thereby tending to maintain the blade coil 66 with the rear unsharpened edge 67 of the blade element 68 in contact with the inner surface of housing member 54, as shown in Fig. 12, and with the sharpened edges 69 of the blade free from contact with any portion of the housing, including the inner surface of member 52 at the outer end of cavity 56. In addition, the outer turn of the coil in travelling continually around the cavity comes into contact with the zones of the side wall thereof which change in angularity with respect to the axis of the cavity from a value somewhat below 3 (at the top of the cavity to the right of line 11-11), to 3 at such line, slightly below 3 at the left of such line, up to 3 again at the bottom of the cavity at line 11l1, and then to 4 at the locationof line 0-0. The blade coil is thus continually slightly flexed as the blade coil progresses around the cavity, so that the coil is constantly acted upon by the side walls of the cavity to thrust the coil in a downward direction as it is shown in Fig. 12.

The curved guides 70 and 74, in immediate communi- @49 1 it t e s ra t l e-s ppgrfin t. bri ge Pp tio n 72 of thelhousingg' hav ej approximatelythe same ra thus? of curvature in. the 'planej'o'ffthe; paper of Fig 10 the side wall of the cavity 56. The curved guides and 74 have the same inclination in the same direction with respect to the direction normal to the main extent of the magazine as the bridge 72, the angle A (Fig. ll) being 2"u pwa'rdl y to the right in Fig. '11 The inclinationof bridge 72 and'of guides 70'and 74 is in a direction opposite to the; inclination of the side wall 112 of cavity 56 .at the location 0. The described configuration and angula'rity of the side walls of cavity 56 not only tend to maintain the'rear edge 67 of the blade in such cavity, in'contact with the rear housing member 54, but also insures the maintenance ofthe rear, unsharpened edge of the blade against the rear housing. member 54at' thefbridge 7 2. In it stravel from location 0-0 in cavity 56 onto guide.v 70 the blade undergoes a twist about its longitudinal axis, such twist being 6 in the described preferred embodiment.

It is preferred to prevent the escape of the free, trailingvend of the blade from the supply cavity 56, upon exhaustion of the magazine. To accomplish this the length of the, blade 68v in the initially loaded supply coil is preferably correlated with the diameter of the takeup reel 76 and the radial distance between at least, one zone of the inner face of the side wall 114 and the outer face of the rim 116 of the reel so that when the takenmp, used, blade jams between the surface 116 of the reel and the side wall of the cavity 53a substantial length of blade remains in the supply cavity The winding knob for the take-up reel is disposed on the rear face of member 8 of the razor head. The stem 118 attached to the outer handle 120 of such winding knob is rotatably mounted in an opening in member 8, being retained therein by the split-spring ring member 122 which snaps into a groove in the stem of the knob inwardly of the plate 8. The inner end 124 of the winding stem, which is'o f'square cross-section, is rounded at its inner end as indicated, such stem being capable of driving connection with the splined opening 104 in the take-.up reel in a plurality of angular positions. Preferably, during loading of the magazine into the razor, the handle 120 is turned so that it lies :horiz onta has shown in Fig. 2, in which position opposite flat surfaces of stem 124 will lie substantially horizontal and vertical, respectively. Preferably, also, the magazines 34 are so prepared before shipment that the splines in the passage 104 on the takeupreel have the orientation shown in Figs. 7 and 8..

When the thus oriented splined opening 104 has the proper sizerelative'to the stem 124 of the turning means, the new magazine, positioned in thelpocket in element 22 as above described, may beswung with such element to the closed position of the razor shown in Figs. and 6; thus the closing of the razor and the establishment of a driving connection between the take-up reel and itsturning means will not dist urb the position of the magazinein the pocket of the holder22. Should, however, either the stem 124 or the splined opening 104 not be properly angularly aligned to allow this, the stem 124 may be turned slightly so that the magazine will slip, over easily and so that the stem will not then disturb the initial accurate placement of the magazine in the pocket.

' Afterthemagazine34 has been initially located in the pocket in element 22, which may be done readily by positioning the razor as shown inFig. 4 and by allowing the magazine 34, positioned with the exposed sharp edge 69 of the blade at the lower left, to slide down the inner surfaceof the member 24 a short distance to seat in the pocket, memberIZZ w th its contained magazine is then swun'gclockwise, as thegrazor is shown in Fig 4.

8 and 24. i H K Member 22 is held in such closed position, and magazine 34 is constantly thrust into the pocket'in ele'me'ntf22, with the top of the flange 96 accurately. fitting into the re-entrant angled seat provided by the inner. surface of part 32 and the bottom inner surfaceof lip 36, and with ears fitting within pockets 77 in element22, byf'means of the razor closing and magazine pressing means'now to be described. Insuch position themagazine 34 is ac? curately located in the pocket in element '22 by theafo'resaidengagement in the seat at the top thereof and also by. reason of engagement of the bottom 'rea rpor'tion. of the magazine with the bottom and top locating pads 126. and 128 on the inner surface of the plate 8 most clearly shown in Fig. 9. 'Such pads are separated by the groove.

. designed to be received in the longitudinal opening 18 extending axially of the handle 4 at the top thereof. Such opening'lS has a bridge member 138 on the upper end thereof, such bridge members being slotted longitudinally from the top of the'handle as shown at 140, Below, the bridge member 138 the handle is provided with an open ing 142 extending transversely therethrough, such openingl receiving the nut 144'. Below the opening l'42ithe, handle hasthe axial blind passage 146 receiving the pilot pin 150 on the elongated razor latching and magazine, securing member generally designated 148.

The handle and the latching member 148 are assembled on the portion 6 of the razor head by disposing member 148 in the channel 16, by inserting the nut 144 in the opening 142 in the handle, and by thrusting the handle and nut toward the portion 6 of the razor, the nut being turned toengage it with the threaded shank 152 of the member 148. When the member 148 has thus been fully retracted by the nut 144 the outer member 156 of the latching member will have been fully received in the slot so that the top end of the handle may be engaged with the bottom surface of flange 10 of the razor head; The razor handle may then be permanently secured to the head by subjecting the handle, which isof thermoplastic material, to the action of high frequency heatin g in the vicinity of the channel member 1 6. The plastic material immediately adjacent the teeth 136 becomes softened-and and flows into such teeth, thereby forming a strong me}. chanical interlock between the channel member and the. handle. f

The razor latching. and magazine securing member 148; is provided, as shown, with a first cam surface 154, formed on the rear edge of the main extent of the member. Surface 154 has an a'n'gularity generally matching with that; of the face of thecam pad 106 oh the bottom of the magazine 34. 'When member 148 is thrust upwardly, mid the position shown in Figs. 5 and 6, surface 154 stronglyengages the cam pad 106 to thrust themagazine upwardly into contact with the re-entrant seat formed by thelip 36 and rearwardly at the bottom into contact with the locating, pads 126 and-128. In order to hold the portion 24 of the'razor in closed position so that the magazine receiving pocket therein is closed, the meinber; provided with an outwardly and upwardly inclinedtprojecting member 156 which is designed to overlie the lower edge of member 24. The inner surface, 15,8 ofrmember.

v. 9 i 156 is inclined as shown to interfit with the cam surface 160 at the center bottom edge of member 24 so as to retain such member in closed position.

It will readily be appreciated that when it is desired to remove the magazine 34 from the razor, as, for example, when the blade is exhausted, it is necessary only to turn the nut 144 to retract the member 148 downwardly, thus withdrawing the

154 and 158 from the magazine and cover 24, respectively. When this is done, and when the razor as it is shown in Fig. is tipped somewhat counterclockwise, the member 22 will swing outwardly 2nd will allow the magazine 34 to fall out into the users and.

As above indicated the razor of the present invention is characterized by its simplicity of use, by its ruggedness, and by the accuracy with which it positions the exposed operative length of the blade in shaving position. In a preferred embodiment of the magazine, although this obviously is not necessary, the take-up reel of the magazine is made of such size that on the average during use of the entire length of blade in the magazine a 180 turn of the knob 118 will bring an entirely new and unused. length of razor blade into the operative, shaving, position.
