15 Claims.

My invention relates generally to a safety razor and more particularly to a razor devised for blade replacement by a dispensing blade magazine; my invention relates generally also to a dispensing magazine and more particularly to a magazine devised for detachable association with a razor for blade replacement.

One of the general objects of the invention is an improved razor of the type wherein a blade is enterable endwise thereinto.

Another general object is the provision in a razor of improved means for locating a blade with its shaving edge in proper relation to the guard.

Another of the general objects of my invention is improved means for holding the blade in shaving position and more particularly of means whereby the blade when soheld is given a transverse fiexure.

. Another general object of my invention is a razor having an improved arrangement for permitting the attachment thereto of a blade magazine for blade replacement.

Another general object of my invention is an improved blade container and coordinately of improved means therein for dispensing a blade therefrom.

A more particular object of the invention is a construction for the attainment of the aforementioned general objects wherein the blades are of the double edged type.

Some of the features of invention for the at tainment of the aforementioned and additional objects are these: blade clamping means in the razor which are elevatable to elevate a blade clamped thereby, from a lower level for blade reception to a higher level for shaving performance; means in the path of the blade as it is elevated, to cause the blade to flex transversely; a fixed seat upon which a blade entered into the razor is initially received and a separate blade seat which is elevatable to engage the seated blade and lift itofi said fixed seat; a blade seat elevatable to and above the plane of a blade entered into the razor and locating means thereon engageable with the blade before the seat engages and elevates it; fixedly related top and bottom members and blade clamping elements therebetween which are initially movable relatively to each other into adjacency and then movable together relatively to said members to bring the blade into its shaving level; a resiliently biased member in the blade chamber of a razor for exerting pressure on a blade being entered thereinto for engagement by locating means in the razor; a razor head whose blade channel has an entrance mouth capable of receiving boththe attaching finger and the ejecting slide of a magazine; a razor whose blade chamber entrance is substantially deeper than blade thickness whereby a blade may be entered at a level above the blade seat to gravitate thereupon; a blade feeding magazine having an attaching finger enterable into a razor to form part of the blade receiving seat in the razor; a blade dispensing magazine attaching finger leveled to and forming a continuation of the bottom wall of the blade discharge mouth; a blade feeding magazine having an attaching finger enterable into the blade receiving chamber of a razor and a guiding member engageable with the razor for leveling the attaching finger to the level of the chamber and more particularly wherein the member levels the finger in advance of its entrance into the razor.

For the attainment of these and such other objects as may hereinafter appear or be pointed out, I have illustrated an embodiment of my invention in the appended drawings, wherein:

Fig. 13 is a horizontal section taken on line i3l3 of Fig. 12.

The razor head i2 comprises a hollow frame having a top portion 28 and a bottom portion 36 (see Fig. 1). These portions are preferably formed separately as shown in the exploded view of Fig. 2 because of manufacturing considerations and convenience of assembly. When assembled, they constitute an integrated frame structure with the top and bottom portions in spaced apart relation to provide a chamber within which the blade and the locating and clamping means therefor are receivable in the manner and for functioning as hereinafter to be set forth. It will be understood, of course, that many if not most of the objectives of my invention are attainable even though this frame is made other that of two separate members. For convenience of reference, the top frame portion 2!? will hereafter be referred to as the cap and the portion 30 as the razor frame seat.

The cap is shown at the top of Fig. 2 as provided with end walls or flanges 2| and 22, preferably formed integrally with the connecting web portion therebetween.

The means for securing together cap 253 and razor frame seat 39 shown in Fig. 2 comprise lateral extending grooves 23,'on the depending end walls 2! and 22, which slidably receive mating projections 33 on the frame seat. The two parts may be secured in this relation as by locking pin 24.

A slot extends through end wall 2| of the cap member and is so dimensioned and positioned to permit ejection of a used, dull blade from the razor. The opposite end wall of the cap is provided with a similar slot 26 to permit insertion of a new blade into the razor chamber. This slot 26 is substantially wider than blade thickness and is further widened centrally, both upwardly and downwardly, by portions 2'! and 28 for purposes to be later described. Widened portion 28 is laterally extended by a pair of wedge shaped communicating recesses 2s.

The central longitudinal web portion of cap 23, extends for a distance slightly more than the length of a blade and is provided with downward blade engaging abutments 45 at the sides of its inner surface. The under surface is sloped at M to permit blade flexing by abutments E5 and is also recessed for its entire length at M, to receive the spring 42 and the pressure pad or upper clamping member 50.

The razor frame seat 30 has an upper blade receiving and blade ejecting surface 36 which is provided with side flanges 3| serrated to form the razor guard. The blade receiving edge of seat 3-"; is beveled downwardly as indicated at 3?. Through the seat are a number of downward passages 32 which permit egress of soap, lather, shaving cream and the like. A downward extending recess 34, shaped to receive the locator or lower clamping member 'Hl wholly within its confines, is formed centrally of seat 36. At the blade entrance end of the seat there is formed a channel which extends from the end edge inwardly to communicate with channel 34 and seat.

upwardly to open through blade seating surface 36. At each side of channel 35 is a wedge shaped extension 39 which aligns with slot 25 of the cap. At the bottom and centrally thereof, razor frame seat 36 is provided with a collar 38 whose bore communicates with the bottom of recess 34. The under surface 46 of, the razor frame seat 3% extends to meet with the guard edges 3|, and is formed flat at the bottom and thence curves upwardly and outwardly on each side in alignment with the bottom edges of cap end walls 2% and 22.

The blade supporting means within the razor head frame preferably comprise a pair of upper and lower clamping members 5% and 1B, respectively, and a pressure spring 4.2 which coact to receive the blade at a lower level in the head and thereafter elevate the blade to an upper level for shaving action. The lower clamping member "iii acts as a supplemental blade seat and clamping member and is rectangular in shape and enlarged in width centrally to conform in configuration to the shape of recess 34. The lower clamping member 10 is provided on its upper surface with the protruding fixed pins H which are adapted to be received in the outermost of slots 63 of the blade. Pins H are formed with conical or beveled heads havingan annular cylindrical surface 72 at the bottom which abuts the end edges of the blade slots 53 when the blade is seated in its final position on the locator. The conical surface facilitates the entrance of the pin into the outermost blade slots 63 and will serve to move the blades to their proper location by wedging action, should they be inserted into the razor slightly off center. The pins ii are fixedly secured into the locator ill by any desired means as by force or friction fit. The upper surface it of the lower clamping member if: is convexly curved so that the blade is supported centrally to permit the blade shaving edges to be flexed downwardly. A large orifice 14 extends upwardly through the widened central part of the lower clamping member it for reception and attachment of handle parts.

The upper clamping member or pressure pad is a rectangular member provided with openings 5!, extending upwardly therethrough to receive the locating pins El, and a pair of longitudinal lugs 52 which have upward extensions 53 for reception in mating channels 54 defined by shoulders at the ends of channel 4! in the cap 28. These lugs 52 guide the presure pad vertically with relation to both the cap and the The upper clamping member 50 is preferably formed with a flat under surface for engaging the top surface of the razor blade til. The upward extensions 53 on lugs 52 serve to space the upper surface of the upper clamping member 50 from the top of the channel 4| at the limit of its upward movement to provide space therebetween for the spring member 52. At least one of the lugs 52 is provided with a blade guiding beveled edge 55.

My improved razor in its preferred embodiment has been constructed to take a double edged blade such as shown at 60. The illustrated. blade is provided with cutting edges 6| on each side and a slot 62 at each end for alignment and stacking purposes in the magazine as will shortly be described. In addition a plurality of central locating slots 63 are provided the outermost of which are adapted to receive the locating pins H within the razor head. It will be understood that many of the objects of my invention are obtainable -a tapered cylindrical bottom 5 with razors constructed to utilize blades other than that shown and described.

The handle'portion II of the razor comprises I3 having a vertically fluted peripheral surface to facilitate gripping with the fingers of the hand. A neck I4 extends upwardly from the bottom and to it is rigidly secured a cam section I 5 by means of locking pin I 6. The cam section I5 comprises a rod shouldered at I I, I8 and I9 to provide sections 8|, 82, 84 and 81 of successively smaller diameter. Section BI is received in an enlarged base at the bottom of collar 38 of the seat. Section 82 is provided with the helical cam slot 83 extending therethrough and flattened at its ends to provide locking action against accidental movement. Cam pin 85 extends entirely through collar 38 and is rigidly secured thereto by force fit of its knurled end portion. The cam pin also extends entirely through section 82 of the handle, riding in the cam slot 83. It will thus be observed that rotation of handle part I3 in one direction will lower rod I5 in collar 38 as shown in Fig. 3 through coaction of the fixed cam pin 85 with the cam slot, while rotation of the handle in the opposite direction will serve to raise the rod in collar 38 to the position shown in Fig. 4. Above the cam section 83 is handle section 84 which is received in a reduced passage at the upper end of the bore of collar 38; Shoulder I9 serves to seat the flat bottom of lower clamping member Ill. The lower clamping member I is secured to the rod I above this shoulder by any desirable means, the preferred means illustrated comprising a washer 86 over which the end portion 81 of rod I5 is peened, in a manner which will permit the lower clamping member 70 to rotate with respect to the rod and yet move linearly in vertical directions by reason of abutment with the shoulder I9 and the walls of recess 34.

When the razor parts described above, and shown in exploded view in Fig. 2, are assembled, the razor will have the appearance illustrated in Fig. 1. It will be observed that the improved razor comprises a head which has spaced upper and

lower members

20 and 30 which are fixedly related to define a blade chamber which is open at the sides and provided with a blade ingress aperture in one end and a blade exit aperture at the opposite end. Once a blade has been received into the chamber and seated on the resupported by the lower clamping member 10 at a position higher than the abutments 45 on the cap in the manner shown slightly exaggerated in Fig. 6. At this time the upper clamping member 50 is carried almost wholly within the recess 4| in the cap. I

My improved blade holding and feeding magazine I00, shown in Fig. 11 comprises a preferably unitary casing IOI closed on all sides except the rear. The rear is adapted to be closed by member I It which bears a forwardly projecting platform I I I whose sides are provided with a pair of latching projections H2. These projections are provided with surfaces I13 which are beveled forwardly and upon insertion of the closure into the casing IOI are adapted to spread the side walls thereof, until the detents II3 fall into the vertical latching grooves I02 in the walls. The grooves have surface I03 beveled rearwardly so that removal of the closure will, through action of projection I I2, serve again to spread the magazine walls sufiiciently to permit removal. The closure member is also provided with. vertical lug II I projecting forwardly therefrom into the space normally occupied by the razor blades. A similar lug I04 is carried by the inner surface of the front wall I05 of the magazine casing. The

I two lugs IM and H4 function as aligning means ceiving seat 38 as shown in Fig. 3, the blade is securely positioned thereon by'pressure downwardly of the upper clamping member and spring member 42. The lower clamping member at this time is seated wholly within recess 34 so that not even the tops of its locating pins II are in engagement with the blade. Rotation of the handl I3, bycoaction of the cam slot and cam pin, will serve to raise the lower clamping member I0; first to engage pins H in blade. slot 63 at the outer ends thereof; next to engage the bottom of the blade against the top curved surface of the lower clamping member 10 with the conical portions I2 of the pins II extending into the openings 5| of the upper clamping member 50; and finally to lift the blade against the resistance of the upper clamping member 50 to an elevated position in the blade chamber with the upper surface of the blade engaging abutments 45 on the cap 20 adjacent the shaving edges of the blade so as to flex them downwardly in the blade shaving position. In this position the blade edges extend outwardly through the side opening in the blade chamber and the blade is centrally bottom of slot for holding the stack of blades 60 properly aligned within the container, all of the blades except the topmost one being adapted to register their end slots 62 with the aforementioned lugs. The top surface of the magazine container is slotted at I06 from its rear end to a point close to its front side. This slot permits the forward travel of ejector I20, which is provided with a narrowed neck I2I to ride in the slot. A ridged finger manipulating portion I22 is bent forwardly from the neck and slides on the top surface of the container. A similarly shaped, pusher portion I23 is bent forwardly from the neck and biased upwardly toward the under surface of the container top. In the retracted position of the ejector, part I23 sits on or just above platform III at the rear of the stacked razor blades, and its side edges seat within the channel defined by a pair of parallel abutments I01 carried for its full length by the under surface of the con tainer top. Pusher part I23 extends below these abutments a distance equal to slightly less than the thickness of one razor blade so that its front edge will engage the rear edge of the topmost blade to eject it from the container. The topmost blade is carried above lugs H4 and I04 by the pressure of spring I25, and its upper surface rests against the under surfaces of abutments I 07. When in this position thetopmost blade is in alignment -with blade ejection slot I25 which extends through the front wall of the container. The upper edge of slot I25 is relieved at the ends and centrally thereof between abutments I01, so as to offer less friction to movement of the blade through the slot, and the widened central portion permits the projection therethrough of pusher part I23 at the forward limit of its advancement. The lower surface of the slot is relieved at the ends for the same reason. and centrally thereof falls into the same plane as the upper surface of lug I04 as well as the upper surface I32 of attaching finger I30. A blade being ejected through the slot is therefore supported at its front by the top of lug I04, the I25 and the top surface of finger I30.

The magazine attaching finger I30 protrudes forwardly from the front face of container NH, is generally rectangular in shape, and is provided witha pair of wedge shaped lateral projections l3i. Finger I when inserted into the razor is received in aligned grooves 28 and so that the finger top surface may perform its blade supporting function while the blade is traveling from the magazine into the razor, see Fig. 8. The upper surface I32 of the finger I30 therefore is adapted to form a part or continuation of the blade receiving seat 36, and the wedge shaped lateral projections I3I are received in mating recesses 39 and 29 extending laterally from.

grooves

35 and 28 so as to prevent upward tilting of the attaching finger I30 in the razor.

Spaced below the attaching finger is a second, guiding finger I projecting from the front wall Hi5 of the magazine. Finger M0 is provided with upwardly flanged side walls MI, and this finger extends forwardly a greater distance from the magazine than does the attaching finger itii. The side walls [4! slope downwardly and inwardly so as to provide a guide surface for the lower part 46 of the razor. In order to attach the magazine in the razor, for purpose of in 1 sertion of a new blade, one end of the razor is merely seated on the magazine finger 149 between the side walls M! as shown in Fig. '7. The magazine and razor may then be pushed toward each other, and attaching finger [3% will be guided by the upper surface of the guiding finger, into opening 28 in the razor. The magazine and razor will then be frictionally secured. together and positioned relatively as shown in Figs. 8 and 10.

When thus attached'the upper surface I32 of the attaching finger falls slightly above the lower edge of razor entrance passage 26 and slightly below the blade receiving seat 36 in the razor. The pusher I22 may then be advanced manually to start the insertion of a new blade into the razor. At the beginning of such blade movement the forward end of the blade, as it enters slot 26 of the razor, is supported by the magazine finger I30 as previously indicated until its forward edge reaches the beveled portion 3'! of the razor receiving seat, see Fig. 8. As blade advancement is continued the forward edge of the blade rides up the beveled portion 36 and engages the beveled surface 55 at the edge of the upper clamping member to be guided onto receiving seat 36 and under the upper clamping member 50. Further advancement of the ejector pushes the blade entirely into the blade chamber of the razor against the resistance of the upper clamping member 58, so that the direction and extent of travel of the blade is limited to that imparted by the pusher. At the limit of its forward motion the pusher extends into slot 21 of the razor cap and the new blade is fully entered, occupying the position shown in Fig. 9 (see also Fig. 3). The blade may now be elevated to its shaving position in the manner previously described.

It will be noted that the widened blade entrance 26 to the razor, the positioning of the blade receiving seat 36 above its lower edge plus the bevels 3? and on the seat and upper clamping member 50 respectively will permit a new blade to find its proper level on seat 36 regardless of the level of its entrance into slot 26. This arrangement has the advantage of permitting relatively large manufacturing tolerances and error in all of the mating parts including the attaching finger while guaranteeing operability of the combined razor and magazine to inject new and eject old blades. The device is operative for these functions even though under certain manufacturing conditions the upper surface 132 of the attaching finger finds a level above.

receiving seat 36, for in this case the new blade would still be guided under the upper clamping member 50 and supported at one end between the pad and the magazine finger until elevated by the lower clamping member Hi.

It will be understood that the conical shape of the pins H enable the latter upon elevation of the lower clamping member 10 to engage the end edges of slot 63 in the razor blade and shift said blade to center it by an amount equal to the radius of the pins, should the blade have been inserted slightly out of center position in the razor chamber.

Having been provided with a blade in the manner described above my improved razor may be utilized for shaving purposes in the normal and conventional manner. If desired the blade may be lowered from its shaving position for rinsing purposes by actuation of the razor handle it and during such lowering the blade will be securely grasped between the locator and the upper clamping member, and may be re-elevated to shaving position by merely manipulating the handle again.

When it is desired to replace a dull blade with a new blade the razor is conditioned by rotating the handle to lower the lower clamping member "l0 so that the old blade between the two clamping members 19 and 58 is lowered and then held grasped between blade seat 36 and upper clamping member 50 in the manner shown in Fig, 3. The blade magazine I00 may then be attached to the razor and the magazine pusher element H22 manually advanced to force a new blade out of the magazine into the razor in the manner described above. During its movement the forward edge of the new blade as it enters the space between the receiving seat 36 and the upper clamping member 50 engages the rear edge of the used blade; Further advancement of the pusher serves to eject the old blade from slot 25 in the cap as well as advance the new blade. When the old blade is fully ejected and the new blade fully inserted the magazine may be withdrawn from the razor and the new blade elevated to its flexed shaving position substantially as described above.

Having thus described my improved razor and separable attaching blade feeding magazine, it will be obvious that various modifications may be made therein without departing from the scope and spirit of my invention. I therefore do not wish to be restricted to the specific embodiment illustrated and described, preferring rather that my invention be limited only by the scope and spirit of the appended claims.

It will be understood that the magazine I may be formed of any preferred or desired material such as plastic, metal or the like.
