This invention relates to safety razors and' razor blade storage means adapted to cooperate With said safety razor and to thereby replace a used blade therein with a new blade, and is a division of the application originally filed in the Patent Ofce May 3l, 1930, Serial No. 458,150 which has resulted in Patent No. 2,008,211. A

My invention contemplates the vprovision of a simple and inexpensive razor designed for permitting stropping of the blade without removal thereof from the razor, and adjustable toV any shaving angle. Y

My invention further contemplates the provision of a casing for the razor designed to act not only as a handy and portable container therefor, but also as a blade storage means designed to permit the user to quickly change the blade inthe razor while it is in the casing, and thereby eliminating the necessity for handling the blades at any time.

The various objects of my invention will be clear from the description which follows, and from the drawing, in which Fig. 1 is a horizontal section of my improved container taken on the line I-I of Fig. 2, and showing the razor in position to have the blade thereof ejected and a fresh blade substituted therein. l

Fig. 2 is a vertical section of the same, taken on the line 2-2 of Fig. l.

Fig. 3 is a vertical transverse section of the blade ejector taken on the line 3-3 of Fig. 2.

Fig. 4 is a vertical section of the container taken on the line 4-4 of Fig. 2.

Fig. 5 is a similar section taken on the line 5-5 of Fig. 2.

Fig. 6 is a similar section taken on the line E-B of Fig. 2.

Fig. 7 is a vertical section of my improved razor, as it appears removed from the casing ready for the shaving operation.

In that practical embodiment of my` invention which I have illustrated by way of example and referring to Figs. 1 to '1, inclusive, and particularly to Fig. 1, my improved razor there shown consists of a comparatively long, hollow and preferably cylindrical handle 10. The upper portion `1| of the opening in the handle is internally threaded as at 12. The intermediate passage 13 in the handle connects the upper openingv 1| with a wider opening 14 extending less than half way from the lower portion of the handle and upwardly from the bottom thereof. Slidably mounted in the passage 1| of the handle and preferably made in the form of a rod is the spindle 15. Said spindle is of sufficient length to extend through the passage 13 and into the opening 14 and terminates at its lower end in the enlarged piston-like guide and stop 16. Said stop is of substantially the same diameter as that of the opening 14, and guides the spindle by its engagement with the wall of saidl opening, as the spindle is moved relatively to the passage 13. Said stop serves further to prevent the spindle fromfalling out of the handle 10 when the handle is completely separated from the blade holding portion of the razor, by reason of the engagement of said stop with the upper end of the opening 111.4 Extending from the upper end of said spindle 15 and preferably integral therewith is the externally threaded member 11, which is designed to engage the internal thread 12 of the opening 1l. Said member 11 terminates at its upper end in the ball head 18, through the center of which is passed the pivot pin 1S. I prefer to arrange the axis of said pin perpendicularly to the axis of the spindle for the purpose which will be pointed out more fully hereinafter.

Above the handle 10 and preferably secured to the ball head 18 is mounted means for holding the blade in Shaving and stropping position, said means being rotatable relatively to the spindle and to the handle. Said means includes the blade holder which cooperates with the guard 8l to maintain the blade in position.

The blade holder 80 is preferably made of a single piece of sheet material being suitably bent to form a tubular portion 82 and a pair of similar and cooperating flanges 83 and 84 normally pressed toward each other by the spring action of the tubular portion and designed to receive the razor blade 85 therebetween. In order that the ball head 18 may be inserted into the tubular portion 82 and pivoted thereto as above described, a suitable slot 86 (Figs. 1 and 2) is made in the lower pari; of said tubular portion and extends from one end of said portion somewhat past the center thereof. The width of said slot is substantially the same as the diameter of the externally threaded member 11 whereby the parts may be assembled without di'iculty. For supporting the spindle, the pin 19 is secured in suitable openings 81 in the tubular portion 82.

It will be noted (Fig. 7) that one edge 88 of the slot is close to the lower flange 84 of the blade holder and that the edges of said slot are disposed symmetrically about the axis of the spindle 15. It thereby becomes possible to rotate said spindle about the pivot 19 into a position wherein the axis of the spindle lies in the same plane as that passing through the center of the blade 85 held between the flanges 83 and 84, and coaxially of the tubular portion 82. The member 11 gradually passing through the slot 86 and entering the hollow space of the tubular member 82 during its rotary movement about the pivot 19 into the position above described. It will be understood that during the rotary movement mentioned, the handle should be unscrewed completely from the member 11 whereupon said handle drops along the spindle 15 until the stop 16 engages the upper end 89 of the opening 14.

Interposed between the upper end 90 of 'theVv handle 10 and the lower part of the`blade holder 80 is the guard 8| preferably made of a single piece of material. y K are of the usual construction eXcept at the exA treme ends thereof where the materialbetween the teeth, instead of being completely cut away,

is turned forwardly and then upwardly and rear-v wardly to provide the fold 92 having the groove 93 therein for the reception vof the veXtreme Aend portions of the edge of the blade. At itsrear' edge and arranged substantially in the middle portion of the guard, I prefer to provide a slot as 94 of about the same width as the `diam'etc'er on the member 11, whereby the guard may be var-Y ranged in place by arranging the edges rof the slot about said member 11.

To providefor proper adjustment of the blade. to various degreesof shaving such as ne shaves groove 93 .of the guard soY that the edge Aof the blade isarranged closer to the ends of the Vguard teeth: Y Similarly, if the handle is rotated in the opposite direction, thecam members 99 Yare released'from thebevelled end 95,'.thereby allow-y ing theguardV member to be movedv under fthe spring action'of itscurved portion 91 'or' manually forwardly tol position theedge of the blade further from the guard teeth 9 I. l

Itwill be understood thatY the slot $11V is of sufficient depth to provide vthe required adjustment `and kthat the guard may be'selfemaintainedin placebyv the frictional engagement of the sides of'said' slot with thermember 11.

As shown in Fig. .7, the ,razor is in the.Y .proper position; for ,the shaving operation. In order, however; that the razor blade may be .properly stropped, it 'is desirable that the guardY 8|..be iirstrpremoved.4 Toward this end, the handlel' is rotated in the proper direction to unscrew it completelyA from the member 11 and so that'said handle drops along the spindle 15 until arrested by the stop 16.

The guard 8| beingthereby freed, it may be, pulled forwardly to 'remove it fromits engagement with the blade and with the member 11. Thehandle 10 together with the member11' and its spindlemay. now berotated asA aunit about the pivot 19 into a position at right angles to that shown in Fig. '7 wherein. theaXis of the spindle, handle andmember 11"lies in the same planeasl the blade. To prevent movementof the handle relatively to; the blade: holder `80, vj a. screw `Aas The case 99 has a two-fold purpose.

93 passing through the handle and designed to engage the spindle may be provided which when tightened, secures the spindle relatively to the handle. The razor is now in the proper position to allow stropping of the blade or to allow the razor to be inserted into its case 99 until next used. In this position, the razor blade may be stropped in the same manner as is the ordinary barbers razor. The stropping operation need net therefore be described in detail.

It may serve as a container for the razor and as a support for a pile |00 of fresh blades, whereby a suitable f and convenient portable case, protecting the The teeth 9| of said guard Y razor from damage, is provided. The case, however, serves the additional function of enabling the user to eject a used blade and substitute a fresh one without touching the blade with the fingers at any time. It is well known that even the most perfect edge on a razor blade may be rendered imperfect and its shaving qualities impaired by merely touching the edge with theA iinger orany other object.

- Itwill be further understood that necessity for handling blades in the present type of razors is a serious disadvantage as accidents frequently occurdue to the careless handling of such blades. particularly byunskilled persons. My improved case 99,' therefore, is provided with means soon to Vbe described for the purpose of enabling the replacement of the razor blade in the razor without danger of cutting the fingers or damage to theu edge of the blade, as has been indicated.

1 Saidmeans comprises the ejectorV |0| provided at oneend ywith-the knob or handle |92 and mountedrbetwe'en the front wall |93 of the casing and the partition 04 thereof. The side walls |05 of the ejector'II/are provided with Vslots |06 intovwhich the pins |01-projecting fromi the partition |04 and from the wall |63, are inserted. Ih'e ejector is guided in its reciprocatory movement into and :out of the Vcasing bythe bottom |08 of the casing as Well as by the members v|700 and |03 and is also guided and maintained in position by the horizontal partitionv I 99. Suitably 'secured to and vextending from the top I|0fof the ejector is the thin bladeV engaging member of sufficient length to just clear'the pile |00- when the ejectorY |0I is withdrawn from the case into its outermost `position (Figs. A1 and 2). Said pile |00 rests upon the sheet spring V|12 and is normally urged thereby upwardly into contact wit-hthe horizontal partition |09.

The spring II 2 is secured at one end as by means of the rivets 'I I3'to the bottom portionI'I4 of the case, said bottom portion being hinged as at ||5 to-tl'i'e rearwall ||6. The other end||1 of the spring ||2 is bent rearwardly uponitself and engages the lowermost blade of the pile. Said pile `|00 is maintained in position and guided in its upward movement under the influence of the spring ||2 by means of suitable posts IIB. Said posts enter the alignedopenings VI |9Yin the blades' and thereby maintain the 'entire pile of blades in `proper alignment. The posts IIB may The rear` partition as l |2| substantially closes the ejector and blade magazine compartment |22, a suitable slot as |23 being provided at the upper end of said partition for the passage of the uppermost blade out of said compartment when the ejector is pushed back into said compartment whereby the blade engaging member I serves to engage the `forward end of the uppermost blade and to removesaid` blade from the pile through said slot |23. It will be understood that the door H4 maybe opened and the pile of fresh blades arranged on the posts H8, to replenish the case with blades, as desired. Normally, however, the bottom ||4 is closed, being maintained in its closedposition by means of a suitable latch |24 arranged on the front edge thereof and of any well known type.

Means are provided for holding the razor in proper position in the case 99 to allow the blade removed from the pile |00 to be inserted into the razor while at the same time to eject the used blade from the razor out of the case. Said means includes various supports for holding the razor blade in substantially the same position as that previously described in which it is arranged for the stropping operation. That is, the guard 8| is removed and the handle 10 and spindle 15 arranged with their axes in the same plane as that of the blade, as will be seen clearly from Figs. l and 2. To insert the razor into the case, the cover is opened about its hinge |26 to expose the interior of thev case. The opening 14 of the razor is then arranged adjacent the hinged pin |21 and said p-in is inserted into said opening 14.

The razor is then swung down until the tubular portion 82 rests in the partly cylindrical recess |2811 of the support |29a upstanding from the bottom |52. blade holder, rests on the upperv wall |30 extending forwardly from the rear wall ||6 of the case and having its upper surface aligned with the lower edge of the slot |23.

To reinforce and strengthen said wall |30, it is provided with depending side walls |3| which are also secured to and project from the rear wall IB or which are made integral with said rear Wall. To allow the razor to be swung into the position thus described, the pin |21 is provided with a hinged portion |32 pivoted in the groove |33 of the hinge support |34 extending rearwardly from the front wall |35 of the case.

It will be understood that the hinge portion |32 and the groove |33 may be so shaped that the pin |27 can swing only to a substantially horizontal position and is prevented from swinging below said position.

In the position of the blade just described wherein it rests on the upper surface of the upper wall |30, said blade is aligned with the slot |30 in the rear wall H6.

It will be seen that as the uppermost blade of the plie |00 is pushed rearwardly by the blade engaging member toward the razor, the rear end of said blade thus removed engages the front end of the blade held between the members 83 and 84 of the razor and on further movement thereof, ejects the blade held by the razor out through the slot |35 and out of the case. In the innermost position, therefore, of the ejector |0|, a fresh blade has been supplied to the razor and the blade engaging member constitutes the uppermost member of the pile |00 and is supported at its rearmost end by the entrance thereof into the slot |23.

The cover |25 carries the downwardly extending lug |29 whichis suitably recessed as |28 to engage the tubular. portion 82 with the blade holder to maintainthe razor in the case securely against rattling or displacement. To further secure the blade holder against vibration or displacement within the case, a hollow plunger as |39 is adjustably secured at its upper end to the screw |40 projecting downwardly from the upper wall ofthe cover |25.

'Io maintain the plunger |39 against loosening of said screw |40, a suitable spring as |4| may be arranged in the interior of the plunger to en- The blade 85, however, held by the gage said plunger and said screw and thereby to resist relative movement thereof. The lower face of .the plunger |39 engages the flange 83 of the blade holder and serves to maintain it in proper position when the case is closed.

It will be seen that all the parts are maintained in the case normally against movement, and that the cover |25 may be maintained in its closed position by means of a suitable spring latch |42 engaging a suitable stop as |43 projecting from the side wall of the case.

It will be seen that I have provided a simple and eicient razor which may be readily arranged in shaving or in stropping position, as desired, and further, that I have provided means .for encasing the razor when not in use, which means is eective to supply the razor with a fresh blade conveniently when desired.

It will further be seen that the devices herein shown and described are simple, capable of economical manufacture and designed to meet the severe requirements of practical use.

It will further be understood that while I have shown and described a specific embodiment of my invention, I do not wish to be understood as limiting myself thereto but intend to claim my invention as broadly as may be permitted by the state of the prior art and the terms of the appended claims.
