MAGAZINE FOR RAZOR BLADES I Filed Oct. 10, 1936 INVENTOR Uc'TAi/Ius I! Ronmquss Patented a 22, 1938 MAGAZINE FOR RAZOR BLADES Octavius V. Rodrigues, Passaic, N.

5 Claims.

The invention relates to an improved magazine for razor blades, of the type provided with means for ejecting the blades one by one, and as they are ejected, feeding them to position in a razor.

5 The essential characteristics of a suitable device for this purpose are to be observed in the blade magazines illustrated and described in United States Patent No. 1,969,945 to O. V. Rodrigues and United States Patent No. 2,043,046 to 10 Leo Kuhn], and, generally described, they comprise a box-like receptacle in which is inserted a clip or holder containing a stack of blades, provision being made for ejecting the blades one by one and locating them in a razor, head in proper position for shaving.

The object of the invention, broadly stated, is to improve those features of the Kuhnl patent which make it difficult to remove a blade clip from the magazine without destroying the latter or, at

20 any rate, without mutilating or distorting it or parts of it to an extent which will inhibit its further use for its intended purposes.

By utilizing the invention it is possible to dispense blades sealed up in the magazine and in 25 most cases, to prevent the insertion in the same magazine of a second supply of blades, thus compelling the user to discard the magazine when its first loading has been exhausted. Consequently, the razor iproducer may be assured that only blades of his own make or of his selection shall be used in connection with his razor, and he thus avoids the damage to the reputation of his razor,

which would be almost certain to arise from the sale by others of cheap and inferior blades. 35 Referring to the drawing,

Fig. 1- is a perspective view of the magazine; Fig. 2 is a view, in section, on the line 2-2 of 1 Fig. 3 is a view, in section, on the line 33 of Fig. 1;

Fig. 4 is an end view of the magazine, as ob- .served from the left of Fig. 1;

Fig. 5 is a cross-section view on the line 5-5 of Fig. 2; 45 Fig. 6 is an end view of the magazine, as observed from the right ofFlg. 1;

Fig. 7 is a perspective view of the plunger by means of which the blades are ejected.

The magazine that I have selected to il1us-- 50 trate a preferred embodiment of the invention comprises an elongated, box-like structure of channel section transversely, in which a clip containing a number of blades may be inserted and from which extends a projecting finger ID, the 55 function of which is to align the magazine with the razor as described in Patent #1,969,945 above referred to. The box-like structure, which I will term the barrel, comprises what may be referred to (with reference tothe orientation of the device as it appears in Fig. 1) as a top portion I I, an end 5 portion l4, and two side portions l2 and iii, inturned as indicated at H along a line parallel to and slightly remote from their edges, all of which may be formed from a single blank of sheet metal of a suitable pattern. Preferably a gap or 10 slot is left between these edges through which the spring 28 hereinafter mentioned protrudes The barrel may, if the device is to be used in the manner shown in the Patent #1,969,945, be provided as above stated with the finger l0 which, in turn, is provided with the projection I5 and the projection IS. The primary purpose of these two projections l5 and I6 is that of co-acting with the razor to properly open the blade channelof the latter to receive a blade, but, in addition, the projection l6 also performs a function that is related to the invention and which will be later referred to. It will be obvious that the clip l8, whether containing a stack of blades indicated'as a whole by the numeral l9 or empty, cannot by reason of the presence of the inturned edges ll be removed by extracting it through the bottom of the barrel. The same would be true even if the edge of only one side were inturned. Neither can the clip be extracted through the front of the barrel by virtue of the closure constituted of the end wall [4, but even if the end wall 14 be bent so that the end is open, the projection l6 offers a further positiveobstacle to removal of the clip-i. e., unless the finger II) also be bent aside. If it is intended to make use of the projection l6 as an obstacle to the extraction of the clip in this manner, it is preferable that the clip should fit the barrel closely. Extraction of the clip through the rear end of the barrel is effectively prevented by the lug 20 which may be, and preferably is, provided by striking in by means of a punch, a small area of the stock in one of the sides, leaving it however attached along one edge. In assembling it is preferable that the entire barrel be formed except the lug 20, the clip loaded with blades inserted and the lug 20 then struck in.

We thus have a barrel containing a clip for holding a stack of blades which cannot be extracted without removing the obstructions created by the end wall It, the projection l6, and the lug 20. Removal, breakage or distortion of these parts, while possible with special tools, is not feasible for the ordinary razor user, and in any event the operation would result in distortion or mutilation of. the barrel, rendering it unavailable for further use. The same result'would occur if it were attern ted to extract the clip from the barrel by forcibly spreading the sides of the latter.

The bottom of the magazine which maybe copsidered as a part of the barrel may consist of a cover plate 2| preferably turned up at its edges as shown at 22, and folded over the inturned edges ll of the side walls, as shown at 23 and 23.

It will thusbe seen that an attempt .to remove the clip without mutilation or distortion of the'barrel is not in any way helped by removing lated to the invention, will be briefly referred to the cover plate. In other words, removal of, the cover plate does not in any way help in the removal of the clip, ii it is desired that the removalis to be accomplished without rendering the magazine unusable. v

The obstacles to removal oi the clip may be increased by forming it from stock that is capable of withstanding very little bending or working. To this end brittle stock may be selected and if possible stool: so brittle that the lug 20 cannot be bent'back out of the way of the clip without rupture along the line of bend or at any rate cannot be bent to its original position and then restored to its position of projection without such an eifect. Thedesired results may be still further approached by using thick stock since the thicker the stock of a given grade the less bending will it stand. Not only would the same diillculties arise as in the case of the lug II in case it were attempted to bend the projection it out of the path of the clip, but even were the attempt successful it would not be feas ible to restore it to its original shape without the use of special dies, and thus the function of the and 3, the spring 2| forces the entire stack ll of blades upwardly, thus interposing the rear end of the blade at in the path of the plunger, and then when the plunger is moved forwardly-'- that is, to the left with reference to Figure 1through a full stroke, the ,blade a is ejected through the orifice 28 of the magazine, and if.

the magazine is properlylined up with a razor, the blade will be inserted in the blade channel of, the latter. The operation is of course re peated until the supply is exhausted as often as it is desired to insert a new blade in the razor.

From the foregoing description it will be seen thatgie invention makes possible an eifective way preventing the indiscriminate selling of cheap and inferior razor blades, with the neces- 5&1! result of discrediting the producer of the razor with whichthey to b W le he the following claims, d
