( Cl. 3ll-dil 3 Claims.

The object of the invention is a razor of the magazine injector type provided with stops for aligning a blade edge with the guard, in which provision is made for means that may be operated positively and unyieldingly to force the said blade edge against the said stops.

Referring to the drawing:

Fig. 1 is a top view of a razor embodying my invention, together with a magazine injector parts being broken away from the razor to more clearly illustrate its construction;

Fig. 2 is a View on the line 22 of Fig. 1;

Fig. 3 is a top plan view of the razor with parts broken away to show the invention;

Fig. 4 is a view on the line 4 of Fig. 1.

Describing the drawing more in detail, the razor comprises a conventional handle Ill in which is socketed the shank I! merging into the back plate I2, which in turn is bent over to form. the top plate it. The bottom plate, or blade support It, terminates in the guard I5 and is an extension at right angles of the plate IS. The extension plate It is hingedly connected to the back plate by means of a hook I l struck from the material of the back plate I2 and engaging in the aperture 88 the extension plate I6 and, by the lugs I9, I9, comprising turned-over portions of the back plate.

A spring for causing the bottom plate, or blade support I4 to bear upwardly against the top plate I3 for the purpose of clamping a blade 26 and also for causing the extension plate It to bear rearwardly toward the back plate I2 is pivoted to the shank II by any suitable means, such as the rivet 2!, and is indicated by the numeral 22. The tip 23 of this spring bears upwardly against the blade platform and effects clamping of the blade 29 between the blade platform and the top plate I3. The bowed portion 24 of the spring bears rearwardly against the bowed portion 25 of the extension plate It and biases the extension plate rearwardly toward the back plate I2 as indicated at 26.

The guard is provided with blade stops 21, 21 against which the edge of a blade may be caused to abut, as may presently be described, and which serve to locate the edge of the blade definitely with relation to the guard I5. The struck-up

ears

28, 28 are merely for the purpose of manipulating the main spring 22-4. e., to facilitate seizing it with the fingers to swing it on the pivot 2| so as to release tension on the blade platform and extension plate I6 to release a blade.

Afiixed to the back plate I2 is a spring 38 anchored at each end to the back plate, one end being anchored by merely crimping the spring around the edge of the back plate, as shown at 3|, and the other being anchored by the rivet The anchorage 3! is, as will be observed by an inspection of Fig. 1, capable of slipping when the spring 332 is flexed toward the back plate and thus elongated slightly, as shown in Fig. 3.

Extending from the spring 30 is a finger 33 which projects through an aperture 34 in the back plate. The length of this finger is such that, when the spring 35 is in its normal position-i. e., its unstressed position or shape as shown in Fig. 1, it terminates at such a point so that the distance between its terminal and the stops 2? is greater than the width of the blades that are to be used in the razor. The finger 33 is also in line with the position that the blade occupies when positioned between the top plate It and the bottom plate I4.

The razor shown is of the so-called magazine injector type-i. e., the type in which a separate magazine is used, such as is shown in Fig. 1. To briefly describe such magazines, although they are already well known, it is sufficient to say that they comprise a boxlike receptacle 4!) containing a stack of blades M and a slide 42 connected to a plunger 43 by means of the turned-over lip 44 extending from the plunger and through the slide and then turned over. As the slide 42 is moved to the extreme reari. e., to the right of the slot 65, it carries with it the plunger 43. Since the blades are spring-pressed in the direction of the slot, the plunger 43 engages the rear end of the top blade and by reverse stroke injects the blade into the head of the razor, at the same time ejecting a blade, if there be such, that is already in the head.

The magazine is also provided with an aligning finger 46 indicated by dotted lines (see Fig. 4), which finger is inserted in the slot 41 between the back plate I2 and the extension plate I6. The dimensions of this slot are such as to receive the finger 46 with a sliding fit so that, when the finger is inserted, the magazine is aligned with the razor so that a blade ejected from the magazine is properly aligned to enter between the top plate I3 and the bottom plate I4. In particular, it should be noted that the thickness of the finger is only such as to permit it to enter the slot freely but with a close fit-it not being in contemplation that there shall be any further separation of the extension plate I 6 from the back plate 12 as a result of the insertion of the finger.

In explaining the operation, it may be assumed that the blade 20 (see Fig. 2) has just been inserted by operating the magazine in the manner above described and that the magazine finger has been withdrawn. It is then necessary to bring the blade edge in abutment with the

stops

21, 21 in order that it may be properly aligned with the guard l5, this proper alignment having of course been predetermined. This is accomplished by pressing the spring 30 against its resistance toward the back plate by thumb or finger pressure, and this operation in turn through the medium of the finger drives the blade into abutment with the

stops

21, 21, as shown in Fig. 3. The pressure of the top plate l3, which is of resilient material and construction is so adjusted as to retain the blade firmly in position with its edge against the stops While the implement is being used for ordinary shaving purposes. Release of the spring 30 from finger pressure causes it to return to its normal position, as shown in Fig. 1.

While I have described a certain particular construction in which my invention is incorporated, I do not desire to be limited to this particular embodiment since many changes and modifications may easily be made without departing from the spirit and scope of the invention as set forth in the following claims:

I claim:

1. A razor comprising a blade platform provided with a guard and with stops on the guard so positioned that a blade edge abutting them is in shaving position, a back plate terminating in a resiliently-pressed top plate for resiliently clamping a blade between the top plate and the blade platform, and a spring mounted on the rear side of the back plate and provided with a finger projecting through the back plate and aligned to exert a thrust against the rear edge of a blade located in the blade channel between the top plate and the blade platform, said spring when unstressed being bowed rearwardly from the back plate sufiiciently so that the terminal of the finger is substantially Withdrawn from the blade channel.

2. 'A razor comprising a blade platform provided with a guard and with stops on the guard so positioned that a blade edge abutting them is in shaving position, a back plate terminating in a resiliently-pressed top plate for resiliently clamping a blade between the top plate and the blade platform, and a spring substantially bridging the back plate and provided with a finger projecting through the back plate and aligned to exert a thrust against the rear edge of a blade located in the blade channel between the top plate and the blade platform, said spring when unstressed being bowed rearwardly from the back plate sufficiently so that the terminal of the finger is substantially withdrawn from the blade channel.

3. A razor comprising a blade platform provided with a guard and with stops on the guard so positioned that a blade edge abutting them is in shaving position, a back plate terminating in a resiliently-pressed top plate for resiliently clamping a blade between the top plate and the blade platform, and a spring substantially bridging the back plate and provided with a finger projecting through the back plate and aligned to exert a thrust against the rear edge of a blade located in the blade channel between the top plate and the blade platform, said spring when unstressed being bowed rearwardly from the back plate suf ficiently so that the terminal of the finger is substantially withdrawn from the blade channel, the said spring being slidingly anchored at one end.
