(Cl. 20G-16) Claims.

'I'he invention relates primarily to razor blade magazines of the type in which blades are ejected therefrom one by one by the action lof a manuaHy operable reciprocating plunger, the tip of which when at the complete end of the working stroke occupies the orifice through which the blades are ejected and more or less but not completely closes it. Especially in the case of a magazine which employs blades provided with nubs for guidance and perhaps other purposes such as are disclosed in the Briggs U. S. Patent No. 2,258,968, issued OctoberVL 14, 1941, the closure of the orifice is far fromrcomplete at any time, since it is necessary to provide al special groove in the bottom Wall of the orifice to permit the nubs of the blades to pass as they are ejected.

The invention is found most usefulwhen employed in the type of magazine razor in Which the magazine forms the handle, the razor head being permanently connectedv With it. The heads of razors of this character are frequently dipped in Water or are exposed to the action of a stream of water and, since the ejection orifice is adjacent the razor head, waterl in such cases is liable to, and very frequently does, enter the magazine through the orifice, particularly when provided with the vgroove mentioned above, and if it reaches the blades in themagazine corrodes them in a short time. However, the invention is also useful in connection with the type of magazine razor in which the magazine is normally del taohed from the razor itself, beingonly connected to it for the purpose of ejecting a blade from the magazine and driving it into the razor head. While magazines of this latter type are not frequently used in a way whereby water can enter them, the orifice especially when provided with the groove mentioned does permit access of damp air, salt Water, and-other corrosive gases which, While notacting as rapidly as free water,

do have an equally deleterious corrosive effect if given sucient time. Magazines of this type are now and'then immersed in water through carelessness or accident, in which case the advantages of the invention are as great as in the case of the type o-f razor first referred to. Both types are fully shown and described in the Briggs patent above referred to, which, in addition, show the ejection orifices provided with the grooves referred to. Disclosure of the two types of magazines referred to in Which the groove in the ejection orifice is omitted appear in United States patent to Rodrigues No. 2,109,017, issued February 22, 1938 (separate magazine type) and in United States patent to Rodrigues No. 1,877,429, issued September 13,1932 (magazine permanently attached to razor). So far as the scope of the invention is concerned, it may be statedthat it extends only to the magazine and that what disposition is made of the blade after it is ejected therefrom-i. e., whether it is driven into a razor head attached to the magazine or into a detachable razor headis immaterial. Regardless of which of the above types of razors isequipped with the invention, the object in either case is to sealthe orifice against entrance into the magazine of the objectionable substances that have been referred to. Y

Referring to the drawing, thefrst ve figures of which illustrate the preferred embodiment of the invention, 'C

f Fig. 1 is a longitudinal sectional View of the magazine with the razor head .mounted thereon and with the blade ejecting plunger in its advanced position;

Fig. 2 is a view similar to Fig; 1 with the blade ejecting plunger fully retracted;

Fig. 3 is a perspective viewV of the razor partially disassembled;

Fig. 4 is a viewon 4 -4 of Fig. 1;

Fig. 5 is an enlarged view of a type of blade used in the magazines to be described;

Fig. 6 is a view in elevation and in section showing a modified form of the invention.

The casing or'housing of the lmagazine is an elongated tubular structure of square cross-section comprising the bottom wall I0, the side wall H, the side wall IZjthe side Walls being bent over into right-angle `flanges i3, and I4, leaving the slot I5 between the edges of the flanges, although the slot is not a necessary feature-it being quite permissible that the top of the casing be entirely closed.

The butt end of the casing is normally `entirely closed by a `finger piece of the plunger, asl will be presently described. lhe other end is closed by a block I6 inserted therein and retained by any of theusual methods ofsoldering or perhaps a tight fit. The block I6V merges into a post Il, on the head 20 ofvwhich is rotatably mounted the razor head proper 2|, having the blade retaining channel 22 into which blades are driven from the magazine from time to time as required to replace Worn blades. The razor head may for shaving purposes be rotated on the head 20 to a position at right angles to the post` I1 after the manner disclosed in the SchickY U.- S. Patent No. 1,730,167, issued October l, 1929. Since this feature ofthe construction, as has been already impliedly noted, forms no part of the invention and is well-known, it will not be described in further detail.

A blade ejection orice 23 is provided between the flanges I3 and I4 and the block IS and serves as a passage through which blades may be driven from the magazine into the blade channel 22 of the razor head or, if the magazine is of the type shown in the Rodrigues U. S. Patent No. 1,969,945, issued August 14, 1934, into a separate razor or they may be ejected to be disposed of in any other desired way. In the bottom wall of the slot there may be, if blades provided with nubs are used, a groove 28 to allow of the passage of the nubs (indicated by the numeral 29) with which the blades are provided as shown in Fig. 5. Y

Within the casing is located a blade Wtray container having a bottom wall 24, an end wall 25, and side flanges 26 and 2I, the side flanges terminating with upstanding ears 30 and 3| for fpurposes which will presently be referred to. A tongue 32 terminating in van upwardly extending hook 33 is struck partially out of the bottom wall of the blade tray container and partially out f the` end wall 25 and is permanently bent slightly upward as shown at 34. The block I6 is undercut as shown at 35, and it will be apparent that, by pressing the tongue down ush with the casing by inserting a simple instrument through the slot IHand thendriving the container forward until the end wallv is flush with the block, the hook 3 3 will engage in the undercut portion 35 of the block.l The container can be released by reversal of this operation. The end wall is provided with a notch 39 (if blades having nubs are to be used) through which the blade nubs Ymay pass as the blades are ejected.

the body be of rubber of any kind or even that it be cylindrical. If it is of natural rubber, it should be vulcanized merely to a resilient deformable state, or materials such as cork and others to be named later that are resiliently deformable may be employed. These materials in general, while deformable, are not compressible beyond a negligible extent, but the square section of the enclosure provides spaces 40 that permit further deformation of the body when a blade or the end of the plunger is driven between the body and the contacting flanges I3 and I4.

f lAs to the cylindrical shape of the body, a cylinder The block I6 is cutaway so that in combina- -side wall 36 and the bottom wall 37, the other side wall being formed by the `end wall 25 of the container and the top wall (when the lplunger is withdrawn) being formed ofthe kflanges I3 and I4.. Prior to assembly of the" container with the casing and the block (the container being fully withdrawable from the casing) a body of natural or synthetic rubber in 4a resilient and deformable state in the `form 'of a cylinder 38 is laid on the bottom wall 31 of the enclosure just described and, 'when the container is locked in assembled position, the cylinder V38 is completely confined and bears with light pressure against all the walls of the enclosure and thereforeV completely closes the orifice including the groove, if any, against ingress of foreign substances such as have been referred to. It should benoted that it is long enough to fill the channel in the plunger which will be later described. It is slightly deformed from the circular section which is caused by the rectangular section'of the enclosure in which it is confined.

The vforegoing ist-he condition when the plunger (to be described) Vislretracted `to a position at which it clears the cylinder. y

The resilient deformable body has been described as composed of rubber (natural or synthetic) in the form of a cylinder. Synthetic rubber particularly that sold under the trade name of neoprene is preferable when the blades in the magazine are covered with Va lm of oil as is usually the case, since such rubber is not ap- -preciably affected by oil-as is 4natural rubber. In point' of lfact, however, it -is not necessary that is chosen merely because it is convenient to manufacture and because it satisfactorily answers the requirements that have been set forth. In any case the length of the cylinder is equal to the inside width of the web of the plunger.

The plunger may be of channel section with the web of the channel contiguous to the flanges I3 and I4, the flanges of the channel section terminating in downwardly extending ears only one of which indicated by the numeral 4I is shown. These ears slide on the ilanges 26 and 21 of the blade tray container. When in fully retracted position, the ears 4I of the plunger abut against the ears 30 and 3l of the blade tray container and further Aretractive movement of the plunger is arrested. The plunger is provided with e linger piece 43 so that it can be easily grasped and operated by the thumb and nger. rl`he web of the plunger extends beyond the depending ears 4I as indicatedat 44 (Fig. 2).

The blades, of which a number are shown vand indicated by the numeral 45, are contained in a trayr having the bottom side 46 and the end walls 4l and 58, both end walls being fore-shortened to provide the slot 50 and the slot 5I through which the web of the plunger passes on its working stroke-i. e., the stroke that effects the ejection of a blade, The slot 5I permits of the passage of a blade over the end wall 41 as it is driven by the plunger. A spring 52 exerting an upward pressure against the stack of blades 45 is riveted to the bottom walls of the blade tray container, and projects upwardly through a slot in the bottom of the blade tray. As blades are ejected one by one, the spring keeps the stack in its uppermost position with the top blade bearing against the flanges I3 and I4. The lug 29a projecting into an aperture in the end wall of the blade tray container is for the purpose of preventing the blade tray from rising under the influence of frictional'contact of the blades with the Vend wall of the blade tray. Trays of the construction described are well known in the razor art, being disclosed in United States patents to Schick No. 1,797,733, issued March 24, 1931; to Kulml No. 2,200,752, issued May 14, 1940; and to KuhnlNo. 2,215,008,issued September 17, 1940.

As the plunger 'is forced inwardly on its working stroke from the position shown in Fig. 2, the tip 44 abuts the topmost blade 53 and drives it in the direction of the Lrazor head. As the blade travels'it'wedges between'the cylinder 33 and the flanges I3 and I4, deforming the cylinder in so doing and passing between it and the flanges. As the motion continues to the position shown in Fig. l, the tipof the plunger likewise passes between the resilient cylinder and the flanges I3 and I4'and, when the plunger has reached the limit of its working stroke as shown in Fig. 1 and a blade has been driven its kfull distance into 4the razor head, the plunger is left where itis until it is desired to 'introduce 'rolls to some extent.

another blade. When so positioned, a complete and effective closure of the groove (if any) and of the blade ejection orifice 23 as a Whole is effected. When the plunger is partly Withdrawni. e., beyond the resilient body 38, the latter resumes its previous shape but still effects a complete closure of the orifice including the groove 2s, if present.

In assembling the magazine, the blade tray is introduced through the open end of the casing, and its position is maintained by the spring tongue struck up from the bottom Wall 24 of the blade tray container. This tongue, While it offers enough friction to prevent the blade tray from falling out through the open end of the casing or from being dragged back on the retractive movement of the plunger, does not interfere With the withdrawal of the blade tray applying to it a simple tool, nor does it interfere with the introduction o-f a substitute tray.

in Fig. 6 is shown a modified form of the inv on. In this case the enclosure in which the resinent and deformable body 6l is contained is elongated shown so that, as a blade or the end of the plunger passes between the body and the adjacent Wall of the magazine, the former This serves not only the purpose of distributing the Wear on its surface but also contributes to an easy entrance of a lade or the tip of the plunger, as the case may be, between it and the said adjacent Wall of the magazine. Before its insertion in place, it preferably approximates a true cylinder, but, when inserted in the enclosure, it is distorted to an oblong section as shown. It may be, and preferably holiovv as indicated by the numeral 62. The material of which it is made may be of rubber of the above described or the equivalents thereof that have been mentioned, or it may be of thin resilient steel or other metal, or thin resilient plastic. The rubber or its equivalent ho'a-fever is preferred inasmuch as it readily forms tight closure. The length of the enclc-sure may be considerably longer in proportion to height than is shown in Fig. 6, if more latitude for roll is desired. it will be seen that as the plunger is inserted to its full distance on its Working stroke, the body will roll to the left as shown in the ligure and, as the plunger is Withdrawn, it Will roll to the right. In the case of the modification of Fig. 6, the groove in the Wall of the blade ejection orice may or may not be present, depending upon whether or not the blades are provided With guiding nubs.
