The invention relates to razors .of the so-called magazine type and more particularly to blade packs to be used in lling and refilling the magazine.

yof the objects of the invention is a blade pack of compact form and make-up that utilizes inexpensive containers or wrappers.

Another object is to enable'thevuser to load the magasine with loose blades which however are Prende@ with ,means for preventing easy dslode' Inentol=` one from another and `whereby the pile olf-blades will be maintained in xed position in the magazineexcept as they are ejected one by one as' needed from the magazine into the shavheed ofthe razori @ther Objects Will appear fisriptori of the invention- Pesoribine the drawings.,

Figs. 13 Aand 14 illustrate modified types of blades.

l Referring more in detail to the drawings, a preferred type of .blade that embodies some of the principles of the invention is illustrated in Fig. fla. 'Ifne blade shown is of a well-known -convenin the course of the tional shape but is distinguished `from such blades in that it is provided with two depressions or indentations- I0 and I l, the process of producing these indentations (which may be accomplished the use of ,a punch and die) creating nubs onte? .comsite sie@` of ,the blade Tee-blades are 5?.

all alike, andthe nubs yare similarly and .uniformly positioned on all of them so that, when the blades are stacked or piled,Y the hubs of Y each blade nestin the indentations of the blade nextbelow it., except of course in the case of th bot-.

tom blade, the nubs ofwhich nest in the bottoni plate. as will be presently explained. Each blade is therefore definitely located lwith respect to bladesl adjacent to it,a-l1;hough` since the nubs and indentations are` ofapproximately spherical contour a slight force isY sufficient `to dislodge them and to cause the blade towhich the -force is applied to slide on the onewith which it contacts. .The contour of theindentations and. nubs is however not invariable, the particularcontour shown being lselected .merely because of its metalworking advantages coupled Withthe fact that it satisfactorily functions to locate'the blades with respect to each other and at the sametime offers a yielding-instead of a positiveresistance to dislocation.y However, `it will become apparent as the description continues that, .while it should be possible to dislodge` a blade for lengthwise movement inone direction, it may if desired be positively prevented against dislodgment in the-opposite direction. 'Ihe manner in which-the nubs and indentations function is illustratedin'Figs. 2, 3, and 4. The number of blades in thestack is a matter ofchoice, although limited of course by the capacity of the chamber of which they are to be inserted.

The Vstack of blades preferably rests upon a plate I-2 (Fig. 5) provided, as in the case of the blades, with indentations indicated by the numerals I3 and I4 located to register with the -nubs on the bottom blade of the stack. The tongue I5 projecting from one end of the plate tips slightly dow-n V(as viewed in the drawings) and likewise the opposite end I6.Y In addition,.twortongues I'I, I'I are struck downwardly to serve as abutments. to cooperate with the lugs I8, i8 projecting laterally from 4 the lifting spring IS (Fig. 5). The functions performed by the'bottom plate and the spring will be later explained. In assembling, the stackV of blades rests ,on the plate I2, the nubs ofthe bottom blade registering .with the indentations I3'and `II of the plate. I To retain Vthe* stack and the plate in assemble condition whereby it will resist forces tending to ldis-,assemble it, I provide the clip 20 (Figs. 1 and 6), whereby it will resist casual forcesf,vwh'ich is ofV resilient material, such as steel or hard brass, the clip being .(as in the case of the-blades) provided with indentations and corresponding nulos 2|, .uzIpalthough in this case only the nubs the razor into function. These nubs register with the indentations in the top blade of the stack. The clip is of U-shape as shown with the legs of the U normally turned inward toward each other so that, when stressed to grip the stack as shown, the latter will be tightly clamped. The bottom leg of the clip is provided with a longitudinal groove 22 into which the nubs of the plate I2 project and whereby the lower leg of the clip is maintained in a fixed position laterally.

The razor combines a shaving head generally designated by the letter A mounted on a post 23 projecting from a hollow handle, generally designated by the letter C, which serves as a magazine for containing the blade stack and also the mechanism for ejecting blades therefrom. It consists essentially of an elongated boxlike structure closed at one end except for the presence of the blade-ejection orifice 24 and open at the `opposite end to permit the blade-inserting and blade-ejecting mechanism to be operated.

-A blade stackr container indicated generally by the letter B is slidably encased in the chamberwithin the handle.l This container is essentially a box with the

' sides

25 and 25 and the end wall 21, the top being open and the bottom being Yapertured, as at 28 to permit the lifting spring to free itself and drop to the bottom of the container when the latter is Withdrawn from the chamber in which itis enclosed. To explain,

it is to be noted that the lifting spring I9 piv-V otally engagesfthe ends of the side walls of the box by means of the

shoulders

29, 29. When the' container'is within the chamber, the free end 30 'of the lifting spring rests on the bottom of then chamber and the spring bows upwardly as Kshown inFig. 11, where the container is emptied of blades and, as shown in Fig. 4, where a full stackof blades is within the container. The normal shape'of the spring when in an unstressed condition is approximately as shown in Fig. 5. When the blade container is withdrawn from the, chamber, the free end 3|) ofthe lifting springV drops tlfirouglrthe aperture 28 in the bottom of the container and down over the end of the bottom wall of thel chamber, and thereforefits presence does not interfere with the' insertionin the container of a stack of blades. Clearance is provided between the upper'edge lof the end wall 21 and the top wall of the casing in order to permit of the passage of a blade and also of the plunger from the magazine through the blade ejection orifice 24. This end wall is centrally notched as shown in Figs;'l and vl1 so that the nubs on the blades will pass freely through. Y

`A'closu're for the container and also for the open end ofthe razor handle is supplied by the block-3| pivoted to the container by the trunnions32, whereby, when the block carrying'with it the container is withdrawn to the position shownin Fig. 6, it drops down or may be swung down to permit of the insertion in the container of a blade pack also as shown in Fig. 6. It will be observed that the block 3| has a slightly inclined surface 33 (Figs. 4 and 6), the purpose of which is to insure a certain and easy entrance when the block (with the container) is moved into the chamber from the position shown in Fig. 6 to the position shown in Fig. 4. The plate 34 retained in position by the rivets 34a and 34h is simply an expedient for establishing a hinged connection between theblock 3| and the blade container. y

Ejection of blades one by one through the blade-ejection orice 24 is effected by means of the plunger 35, which is slidably mounted Within the handle so that it can be reciprocated between the positions shown in Figs. 4 and 11 in line with the blade-ejection orice. It is channel-shaped, the edges of the flanges of the channel sliding along the upper edges of the container, and rear support and freedom of motion are permitted by the fact that it slidably rests on the block 3|. To limit its rearward stroke, an outwardly projecting spring tongue 36 is provided, which on withdrawal of the plunger abuts against the indentation 36a (Fig. 7) in the inside of the wall of the chamber. The container itself may also be provided with a similar spring tongue 3l which operates in a similar way to limit the extent to which the container may be withdrawn from the chamber.

The shaving head (see Figs. 4, '7, and 9) is pivoted to the post 23 so that it can be swung to the position shown inl these figures to receive a blade and then to a position perpendicular to the post for shaving purposes. It consists essentially of a bottom plate 38 and a blade clamping plate 39, which may be angular extensions of the plates 40 and 4I through which the pivoting screw 42 passes, whence it is threaded in the post. The usual guard 43 is, of course, provided. In the blade-supporting surface of the bottom plate 33 there is provided a longitudinal groove 44 in which the nubs of a blade travel in the course of being injected into the shaving head. The position of this groove laterally with respect to the guard is such that, when the nubs of a blade are located in it, the edge of the blade bears a correct or .desired positional relationship to the guard, and'thus blades are all uniformly positioned inl the head. Of course, on the other hand, the position of the groove may be rst fixed and the nubs on the blades positioned to correspond with it.

The. groove 44 registers with the groove 45 in the end wall 46 of the handle and thus the nubs of the blade being ejected travel in it and thence into the groove 44. To properly guide the blades into the groove 45 its entrance may be slightly widened as shown at 4T. It will be observed (see Fig. 7) that one corner of the container is formed to exhibit a diagonally extending facet, as shown at 48, and that (see Fig. 6) the block 3| is provided with ailange 49, of triangular section. Thus, only' the lextreme ends of the cutting edge of a blade in the container can contact with the wall of the container, which of course is desirable to insure that their edges shall not be injured.

The corners of the blades themselves are preferably cut away as shown in Fig. 4a but not suiciently to permit the blade edge to contact with the side of the container. This is shown in Fig. '7.

By reference to Figs. l and 6, it will be understood how the pack may be assembled. The desired number of blades may first be stacked with the nubs of each successive blade beginning with the top blade and nested in the indentations of the blade beneath and (if single edge blades) with the edges all on one side of the pile. The pile may be then placed on the bottom plate I2 with the nubs of the bottom blade nested in the indentations I3 and I4 of the plate and with the tongue I5 at that end of the pack which Iirst enters the blade stack container as the magazine is being loaded (see Fig. 6). The clip or clamp (see Fig. 1) is then applied so that the nubs on the upper leg of the U nest in the indentations in the uppermost blade and the nubs on the plate I2 register with the groove 22 on the lower leg of the U, The legs of the U point vin the same direction as does the tongue I5. The blade stack container having been fully withdrawn as shown in Fig. 6 and the closure block 3| being out of the Way, the pack is then inserted in the container, The clip is then wholly withdrawn (to be discarded if desired), the Cooperating nubs on the upper leg being readily freed from the stack andleaving the stack together with the plate I2 in the container. To prevent withdrawal of the stack as the clip is withdrawn, the container may be provided with a stop 5I) against which the blade `Stack abuts as the clip is withdrawn, tende ing to carryv with it, of course, the blade stack. However, this stop is located low enough so that it ,does not interfere with the introduction of the pack into the container. The closure block 3l may be relieved as shown at 3Ia so that it can be closed without interference from the stop. The clip having been withdrawn, the blade stack container, together with the closure block 3l (the latter being swung up in the process), is driven into the chamber to the position shown in Fig. 4. As thistakes place, the spring I9 is dragged along with the container, its free end trailing along the bottom of the casing, the result being that it is flexed from its normal shape as shown in Fig. 5 to a nearly flat shape, which causes a resilient upward pressure to be exerted against the blade stack. The uppermost blade of the stack, is therefore always pressing against the plunger or against the top wall of the casing (i. e., in line with the blade ejection orice) when the plunger is withdrawn. As blades are fed one by one from the stack, the stressed spring follows upwardly until the last blade has been ejected, In order to insure that the last blade shall not be dragged backwardly by the friction of the plunger as the latter is withdrawn, the lugs I8, I 8 may be provided on the spring against which the tongues I'I,V I 'I abut, there being enough flexibility in the spring to allow the lugs I8, I 8 to travel upwardly in a perpendicular plane.

Actual ejection of the topmost blade of the Stack is eiected by first fully retracting` the plunger, whereupon the topmost blade rises to alignment with it and with the ejection orice, and then advancing the plunger to the position shown in Fig. 4. This action dislodges the topmost blade from the one beneath it, and it is driven into shaving position in the head, guided to proper relation with the guard because its path is fixed by the nubs traveling in

grooves

44 and 45. If it is desired then to use the implement for shaving, the shaving head is swung to a po,- sition crosswise of its supporting post.

The blades all maintain their positions fixedly with respect to eachv other by virtue of the nesting of the nubs and indentations, a condition which is maintained by the pressure of the lifting spring I9.

When the bot-tom blade of the stack has been ejected, the bottom plate I2 has risen to the top of the chamber as shown in Fig. 11. On with-` drawal of the closure block and blade stack container, the bottom blade may be dropped out or manually removed. It has previously been noted that the ends of the bottom plate are tipped downward slightly. This is to prevent its being ejected through the blade discharge orifice. Ii it is attempted to so eject it, the tip of the plunger rides over the end I6 instead of abutas does the preferred form.

ting with it asin the ease of a blade., But even if there is any tendency to eject it through the;

orifice by reason of frictional contact between it and the plunger, the tipped-down tongue I 5 abuts against the end wall of the blade Stack @0.11- tainer which positively prevents it imm passing into the blade ejection orice.

Fia l2 illustrates an adaptation of the invention to the type of razor with which aseparate magazine is employed, The parts indicated gen-A erally by the letter E are in allrespects similar to the parts indicated by the letter C in Fig. .4,- However, in place of the shaving head mounted on the post as shown in Fig. 4, there is provided an aligning ringer 5I which is designed to ente-1- an aligning slot in the shaving head 52 and posi,- tion the magazine and the shaving head with respect to each other so that a blade ejected `from the magazine enters the blade channel inthe shaving head. This shaving head as in the case of that shown in Fig. 4 has a bottom plate and .tations are formed simply by striking out tongues. 60, Si), which constitute the nulos, and at the' same time the indentations are formed yas indi-,- In Fig. 14

indentations

63 and ,64 are made by `striking down the nubsl with a Clie'` cated at E I properly shaped to give them a .semi-conical contour. obviously positively held against movement in one direction, although it is free to slide inthe other direction. However, since it is only necessary Vthat the blade slide in the direction of the shaving head, these would function so far as the purposes are concerned in the same way It will be noted that in all types of nubs illustrated, the nubs and indentations slope .away from the surface of the blade toward one end thereof-ie., the rear end-as the stack is placed in the chamber. This angleV of slope is small enough so that by an en dwise thrust against a blade it may be dislodged from the blade contiguous to it, Vthe nubs merely sliding up on the indented surfaces until the blade is completely free.
