Claims.
The invention relates to so-called magazine razors" oi the type in which blades are fed thereto from a stack of blades contained in a magazine which can be either separate from the razor or permanently attached thereto. An example oi a razor of the type referred to is that disclosed in United States Patent to Rodrigues No. 1,969,945. In razors of this particular type, provision is made for separating the cooperating biede-hoiding parts of the head when desired, in order to facilitate cleaning or inspection or the manual removal of a blade already contained in the shaving head, the latter being the case when it is desired to remove a blade without supplying a new one. However, it has been found that from the practical standpoint it is quite 0biectionable that ordinary users unfamiliar with the construction of such razors should be able to insert new blades by hand-first, for the reason that they frequently cut themselves in trying to manipulate the new blade into position and, second, for the reason that very frequently the blade is incorrectly positioned, which results in poor performance in shaving and in damage to the r itself by cutting or injuring the stops which abut against the edge of the blade. It is therefore the object of the invention to remove these objectionable features as far as possible and make it impossible or at least difficult for the ordinary user or.this type of razor to insert blades without the use of the mechanism supplied for the purpose.
Referring to the drawing which illustrates a preferred form of the invention:
Fig. 1 is a front view of the shaving head of the type of,razor referred to with the guard broken away;
Fig. 2 is a view on the line 2-4 of Fig. 1; I
Fig. '3 is a view of the shaving head with the cooperating razor-holding parts separated;
Fig. 4 iso detail view of the member which I includes the blade platform; I
Fig. 5 is a detail view of the member incorporated into the shaving head for the purpose of presenting or rendering diflicult the insertion of blades by hand.
Describing the drawing more in detail:
From the usual handle II projects thesupporting plate ll terminating in the top blade clamping plate l2. The complementary movable clamp member ll, terminating in the lower blade platform ll, is hinged connected to the supporting plate H by means of the pintle I5 co-operating with the eye 16 struck out of the back plate. For properly locating the movable member II, the lugs H are supplied, these being simply turned-over portions of the supporting plate. The blade platform H is furnished with two stops I I against which the edge of the blade A abuts when the parts are in the closed position shown in Fig. 2, the rear edge of the blade backing up against the supporting plate i I.
parts are so dimensioned that, when in this position, the blade is securely clamped between the top blade clamping plate i2 and the blade platform is and, as has been noted, is also held firmly in position iore-and-aft by means of the stop It and the supporting plate. The clamping of the blade in the manner just described is effected by the-spring is which is so mounted that it can be swung 'on apivot in a transverse direction, thus releasing the parts or locking them together, as may be desired. This part will be presently described in more detail.
The object of the invention is attained by incorporating in the head a member which, when the parts are in process of separation, projects intothe blade channel-i. e., the channel formed by the upper blade clamping plate and the blade platform, thus interposing an obstruction to the insertion of a blade except when the parts are in locked position or nearly so, as shown in Fig. 2.
The
This member consists of a plate 20 hingedly connected to the supporting plate by the half-eye 2i engaging with the pintle 22 formed from the stock simply by punching the hole 23. The plate extends through the slot 200 in the blade platform, with a. sliding lit, and with the clamping member in closed position (see Fig. 2) its free end is flush with the blade platform-i. e., it does not'project into the blade channel. However, it will be noted that the pivotal axis of the mem ber 20 is further from the blade channel than is the pivotal axis of the movable member l3, and that it is also so located that, as the member 20 swings away from the position shown in Fig. 2 it increasingly projects into the blade channel. In order that it may moreefiectively obstruct the insertion of a blade by hand, the underside of the top blade clamping plate 12 may be partially cut away, as shown at 24. This permits the projecting end of the plate 20 to sweep upwardly as it is swung on its pivot further than it could otherwise do.
The aperture 25 in the plate 20 is merely for the purpose of accommodating the eye It in the supporting plate. It may be noted that the width of the plate may be very much reduced from the width as shown in the drawing. 11
fact, it may be reduced to thedimension of a the aperture 32. The shape of the aperture 12 is best shown in dotted lines in Fig. 1, and it will be noted that the knob 28 can, when in a vertical plane, pass through this aperture, but when in a horizontal plane cannot do so. In other words, when the parts are locked together with the spring I! in the position shown in Fig. 1, at which it is resiliently bearing against the movable member 2|, the knob is in the position shown in Fig. 2. On the other hand, when the spring I! is swung in the direction of the arrow It is preferable that its length be such and that its hinged mounting be so located with respect to the location of the hinged mounting l5, l6 and with respect to the blade channel that, as the clamps are separated, it will extend into the cut-away portion 24, as it will thus obviously more effectively serve its purpose. On the other hand, when the parts are in locked position. the end of the member 20 is flush with the blade platform and offers no obstruction to the insertion of a blade in the usual manner by means of the injector.
Since the injector and its method of use are well known and are fully illustrated and described in the Rodrigues patent above referred to, the aligning finger only has been illustrated and merely by dot-and-dash lines in Fig. 1, as indicated by the numeral 33. It is merely sufflcient to say that, when the aligning finger is inserted in the channel (see Fig. 2), it causes the movable member 20 and the supporting plate II to separate very slightly. The effect of this is to relieve the pressure of the stops l8 against the edge of the blade A and, in fact, to cause the stops to move a slight distance from the edge of the blade. A new blade can therefore be readily inserted in the blade channel by means of the injector without contactwith the stops. This slight motion, however, is not sufilcient to cause the free end of the member 20 to project into the blade channel to a distance sufficient to interfere with the movement of a blade into the blade channel. on the other hand, any such small motion is not suflicient to free the parts sufliciently to insert a blade by hand except with great difficulty. If a blade is to be inserted by hand, a much wider separation is necessary/but as will be seen a separation greater than that effected by the insertion of the injector finger results in projecting the end of the plate 20 into the blade channel and thus effectively preventing the operation.
It is recognized that the present invention may be embodied in other constructions than those herein specifically illustrated, and therefore it is desired that the constructions disclosed shall be considered as illustrative and not in a limiting sense.
I claim:
