BLADE FEEDING MAGAZINE Filed Feb. 4, 1952 /J Fig. 1

Fig. 6

United States Patent This invention relates to the construction of feeding magazines in general and more particularly to a type known as blade feeding magazines.

This application is filed as a continuation in part of my copending application, Serial No. 639,540, filed January 7, 1946, now Patent No. 2,590,871, granted April 1,

My novel construction is capable of being utilized in connection with various types of blade feeding magazines, for example, single edge blade magazine or double edge blade magazine.

in accordance with my invention, I produce a feeding magazine for holding a pack of razor blades, wherein said magazine is provided with means for holding the blades in desired position, and wherein said magazine is provided with an opening and with a feeder for moving its facing blade out from the magazine through said opening, and wherein said magazine is provided with means assuring alignment between its front opening and the front opening of its adjoining razor head and with gauging means for guiding the blade from the magazine into said razor head and with means preventing lateral movement of the blade while being moved by said feeder and with means to prevent the insertion of foreign blades into said magazine, and wherein such magazine is provided with a finger for insertion into a razor head, and wherein saidfingcr is of serpentine cross-section thereby increasing the rigidity and strength of such finger.

To illustrate the ordinary commercial utility of my novel feeding magazine in daily life, a feeding magazine constructed in accordance with my invention, of whatever style or type it may be made, could be utilized to great advantage; for example, it is a well known fact that a blade feeding magazine used for injector type razors have no means to prevent the insertion of foreign blades into such magazines through their front openings, such magazines therefore permitting refilling with defective blades, a matter which is objectionable to the user and of great concern commercially to the manufacturer and to the trade in general. And in addition thereto, the finger of the ordinary magazine for insertion into the razor head consists usually of a flat piece of metal which when inserted into the razor head in a quick or forceful manner is apt to bend out of shape, particularly so at the portion adjacent to the magazine body, thus distorting the alignment between the magazine front opening and the front opening of the razor head. Such magazine then becomes useless from an operable point of view and the blades therein a total loss to the user, causing such user irritation and an outburst of ill temper, particularly so when in a hurry to shave, a matter which may result in the discontinuance of using an injector razor. This, of course, hinders greatly the expansion of this particular industry, a matter which is of great concern to the trade in general.

My invention solves completely the abovementioned problems by providing the magazine body with means blocking the insertion of a foreign blade into the magazine and also with means assuring the alignment between the front openings of the magazine and of the razor head, and also with means guiding the blade in its movement from the magazine into the razor head. The finger of applicants magazine is of serpentine cross-section, extending beyond the front portion of the magazine body, thereby increasing the strength and rigidity of the finger, particularly so at the portion of such finger adjacent to the magazine body, thus eliminating the abovementioned objectionable features and, instead, providing the user with the maximum amount of shaving comfort by assuring the shaver with properly constructed non-defective blades movable easily from the magazine into the razor head. This should make for continuous use of the injector razor to an extent whereby the blade feeding magazine, constructed in accordance with my invention, will become an indispensible item with the user and therefore prove quite valuable to the trade commercially.

There is, therefore, thus produced, in accordance with my invention, a blade feeding magazine which cannot be refilled with foreign blades, thus protecting the user against possible injuries or hazardous after-shaving effects which may result from the usages of defective blades. Thus, the blade feeding magazine of the present invention is built in a practical manner and provides great satisfaction and comfort to the user. It is believed that such a magazine can be utilized to great advantage as it will fill a long felt want and therefore prove quite valuable commercially.

The variety of possible applications of my novel construction with different types of magazines is so prolific that for the purpose of illustrating the invention, 1 have selected the specific embodiment of my invention in its application to a blade feeding magazine exhibiting the greatest difficulties. Such a magazine is one which necessarily must conform most rigidly to the contours of the portion of the razor head to which it may be attached and one which has the field of greatest possible commercial use. For this purpose I have selected a magazine constituting a blade containing magazine so that the principles of construction may be best illustrated in a magazine known as a blade feeding magazine.

For a fuller understanding of the nature and objects of the invention, reference is had to the following detailed description in connection with the accompanying drawings, in which:

Referring to the drawing (Fig. 1), numeral 15 indicates the top of the magazine which has a medial longitudinal slot 16 within which a feeding member 17 slides. The feeding member 17 has a fingerpiece 18 at the upper portion thereof with depending opposed flanges 19 for guiding the fingerpiece 18 along the top 15 of the magazine. The front wall 20 has a slot 21 adjacent the top to permit the uppermost blade to pass from the magazine through such slot 21 and thence into the spaced opening to be positioned between the blade clamping members of a razor head structure. Along a side wall 22 and as an extension of said wall there is a corrugated finger 23 to be injected into a corrugated slot of similar size and shape in a wall of a razor for separating the blade clamping members from each other and for positioning the magazine and the slot 21 in alignment with the spaced opening in the razor head so that the blade being ejected from the magazine is guided properly into the razor head and positioned between the clamping members for shaving purposes.

The blade feeding magazine shown in Fig. 2 is similar in construction to that of Fig. 1 except that it is adapted to house and feed two single blades simultaneously. The top 25 has two medial longitudinal slots 2626 within which two feeding members 2727 are positioned for simultaneously ejecting two single blades through slots 21 which are adjacent the top of the front wall 20. The fingerpiece 28 is attached to the top of both feeding members 27 and has opposed depending flanges 2% for guiding the fingerpiece and feeding members of the magazine. Positioned vertically on the front wall is an extending corrugated finger 23 to be injected into a corrugated slot of similar size and shape in a wall of a razor for separating the blade clamping members from each other and for positioning the magazine and the slot 21 in alignment with openings in the razor so that the blades being ejected from the magazine are guided properly into the razor.

Referring to Fig. 3, this magazine is identical to that of Fig. 1 except that the corrugated finger 33 has its corrugations as indicated by arrow A extending beyond the front wall 20" in order to increase the tensile strength and rigidity of the finger 33 at the point adjacent to the Wall 20 to prevent accidental bending of such finger at such point.

The ordinary type of magazine for injector razors is provided with a fiat finger for insertioninto the razor head to hold the front slot of the magazine infull alignment with thefront slot of the razor head so that a blade could be moved from themagazine into the razorhead for shaving purposes. The thickness of such blades is approximately about 10 or 11 thousandths of an inch and the slots are of such size that only one blade at a time can be moved therethrough. It happens occasionally that such finger becomes accidentally bent and places the magazine out of normal position, mostly does such bend occur at the point adjacent to the wall portion of the magazine from which the finger extends, particularly so when being forced roughly by a user into its position within the razor head, such change of position naturally distorts the alignment between the slot of the magazine and-the spaced opening of the razor head. The blade moved from the magazine slot cannot enter the spaced opening of the razor head, and such magazine then becomes inoperative and the blades therein a loss to the user.

The abovementioned troublesome and objectionable features result from the fact that the proper alignment of the slots depend entirely upon the finger of the magazine which consists of fiat sheet metal (usually having a flexing tendency) and is being positioned within the head structure without the assistance of any other supporting means.

My invention eliminates completely such objectionable features by providing the sheet metal finger with longitudinal corrugations extending into the Wall portion beyond the point where such finger begins I provide ridges whieh-increase gre'atly the tensile strength-ofsuch finger an'dresists fiexing'tendency at suchpoint; thereby greatly minimizing possibilities of accidental bending of such finger while being placed into the spaced'opening of the razor head, thus assuring proper alignment between the magazine slotand the spaced opening of the razor head for feeding a blade from such magazine into such razor head for shaving purposes.

I desire to point out, that of particular importance,-is the means for increasing thetensile strength of the finger at the point adjacent to the magazine body where the finger begins. This particular portion of the finger is apt to bend more readily. The fact that my invention teaches theprovision of means for reinforcing this particular section, is an important contribution to the art. The corrugated forms upon the finger extending into the Wall portion of the magazine, bridging the point where the finger begins, increases the tensile strength and rigidity of the finger at such point to a degree-whereby bending of such finger, while placing same into the razor, is eliminated; thus greatly aiding in the performance of holding the magazine in proper alignment with the razor. In addition thereto my magazine is provided with gauges engaging the head portion of the razor adjacent to the slot, thus placing the slot of the magazine directly opposite the slot of the razor head so that the blade can easily be moved from the magazine into the razor head. This is particularly-true with respect to Fig. 6 wherein the platforms form guiding means leading the blade directly into the slot of the razor head while being moved out of the magazine.

Referring to Figs. 4 and 5, there is shown a blade feeding magazine which is identical to the magazine shown in Fig. 1 except that, if desired, the front portion of the magazine may be provided with projecting opposed spring clips 44 for gripping the razor head above and below the slot or spaced opening within the razor thereby increasing the assurance of proper alignment of the slot 41 with the spaced opening in the razor head so that the uppermost blade 45 may pass safely from the magazine through slot 41 and into the spaced opening within the razor head without danger of marring the cutting edges of the razor blade. The clips are provided with curved end portions to facilitate spreading of such clips for gauging and guiding the magazine into proper alignment with the razor head.

If desired, the magazine may be adapted to house a double edged blade; the top 65 of the magazine may have two longitudinally opposed slots 66 within which a pair of feeding members 67 move. Attached to the top of the feeding members 67 there is a ,fingerpiece 68 which moves along the top65 and has depending opposed flanges 69 for guiding the fingerpiece and the feeding members 7 on the magazine. The front wall 60 is recessed and has a slot 62 directly beneath the top 65 to permit the uppermost blade to pass from the magazine into the razor. Projecting from the bottom 64 there is a horizontal corrugated finger 63 as indicated by the arrow B and beneath the longitudinal medial portion of the top 65 there is a groove 61 within which is positioned a pair of spring elements 62 which are adapted to be positioned within the longitudinal slots 75 of the stack of razor blades within the magazine so that the blades cannot shift laterally,

7 thus preserving the cutting edges of the blade during movement of the blade at the time it is being ejected.

In all of the magazines herein referred to there is a spring member such as 74 attached to the bottom of the magazine which creates an upward pressure upon the stack of blades so'that an uppermost blade is always in position to be ejected from the front slot.

If desired, the magazine may be provided with a rear wall 72 which is spaced inwardly from the rear edge 76 of the magazine so that there is ample space for the feeding members 67 and fingerpiece 68 to move behind the stack of blades in order to permit the feeding members 67 to engage the rear edges of the blade for the purpose of ejecting the uppermost blade. The rear wall 72 has a vertical ridge 73 running up to just below the uppermost blade in the magazine for aiding in the alignment of the stack of blades to prevent lateral movement in the stack of blades, thus ensuring against marring of the cutting edges. The front wall 60 has a similar vertical ridge 77 to act for the same purpose upon the front of the stack of blades.

If desired, the razor head may be provided with a projecting member 80 which is adapted to fit snugly within a recess in the front of the magazine for example as shown in Figs. 6, 9, l0 and 12. The razor may be provided with a horizontal slot 81 just below the top 82 of the razor so that when the projecting member 80 is positioned Within the recessed front of the magazine, the slot or opening 81 of the razor will be in perfect alignment with the slot 62 in the magazine in order to ensure the receiving of the uppermost, blade within the razor. It should be noted that the top 83 of the projecting member 80 is pitched downwardly to aid in the positioning of the razor within the recessed front of the magazine and to guide the front edge of the uppermost blade into the slot 81 of the razor.

Beneath the projecting member 80 and centrally located is a corrugated slot 84 which is of similar size and shape as the corrugated finger 63 and permits the corrugated finger 63 to enter therein in order to separate the blade clamping members from each other and to properly align the razor and the magazine so that the slot 62 of the magazine is in perfect alignment with the slot 81 of the razor, permitting the uppermost blade to be ejected from the magazine and into the razor without marring the cutting edges of any such blades.

It is obvious that magazines made in accordance with my invention will always be properly aligned with the razor, especially for example in view of the auxiliary aligning means, for example, the means for reinforcing the tensile strength of the magazine finger, particularly at the point adjacent to the magazine body, or such as the recessed front of the magazine shown for example in Fig. 9, or the opposed spring gripping clips as shown in Figs. 4 and 5 so that the slot of the magazine will always be in perfect alignment with the spaced opening or slot of the razor, thereby assuring easy and perfect movement of the blade from the magazine to the razor without man-ing its cutting edges.

It is also obvious that the magazine made in accordance with the above invention is so constructed that a blade cannot be injected by a user into a magazine from which the blades have been ejected. The construction shown in the magazine of Figs. 6, 9, 10, and 12 with respect to the spring members 62 can readily be adapted in the various types of magazines shown and described herein.

It is obvious that various changes and modifications may be made in the details of construction and arrangement of parts without departing from the general spirit of the invention.
