' I (Creo-s3) I 2 Claims.
This invention relates to safety-razors, and refers more particularly to means for covering the edges of razor blades carriedby the razors.'
This application is a Acontinuation-in-part of my co-pending U. S. patentfapplication Serial Number 421,270, iiled December 2-, 1941, since matured into Patent No. 2,320,374, dated June 1, 1943, describing a safety razor having two clamping members which are connected with two levers and which may be moved through the central opening of a double-edge razor blade by the pressure of clamping means engaging these two levers, whereby the clamping members clamp this blade upon a guard. l
An object of the present invention is to improve the construction of safety razors not only of this type, but of many other types as well, through the provision of suitable means for covering the edges of razor blades carried by the razors, thereby protecting from injury the users of such razors.
Another object is to combine means covering the edges of razor blades with meansvarying the type of shave possible with such blades.
A further object is the provision of a safety razor having edge-covering means which serve at the same time lfor facilitating the cleansing of the razor. Y
Other objects of the present invention will become apparent in the course ,of thefollowing specification. l
In accomplishing the objects of the present invention it was found desirable'to-provide a safety razor carrying elongated covering elements,.
which may be pivotally-mounted upon the corresponding edges of theV guard and which x are used to cover the sharp edges of a'razor blade mounted upon the razor. These covering elements may have Yexcentric surfaces extending closer to or further away-.from the `sharp edgesI of the blade, dependingupon the position of the covering element. The variation will affect the shaving operation, making it possible to have closer or less close shaves without changing greatly the pressure exerted user.
The cleaning of the razor is facilitated since the turning of a covering element will expose those surfaces whichreceive soap and hair particles during the shaving.
The invention will appear more clearly from the following detailed description, when taken in connection with the accompanying drawings showing, by way of examplepreferred embodiments of the inventive idea.
In the drawings:
Figure 1 shows in side elevation a safety razor in its clamping position;
Figure 2 is a transverse section through the by the hand of the' head of the safety razor, in its inoperative position;
Figure 3 is a top view of the safety razor;
Figure 4 is a top view of a razor having differently constructed covering elements;
Figures 5 and 6 are a section and an end View, respectively, showing the covering element of Figure 4 in dilerent positions.
The safety razor shown in Figures l., 2 and 3 of the drawings comprises a handle It which may be hollow and/or filled with a light-weight fluid and which may be provided with a number oi suction cups II (Fig. 1) for attaching the razor to any suitable surface, such as the edges of a bath tub.
The head of the razor includes a U-shaped frame I2 having a transverse piece I3 which is r'mly connected to the handle I0 and two legs or frame posts HI and I5 having convex top surfaces IS and I'l, respectively (Figs. l and 2). The frame postI I 4 is provided with an arcuate slot I8, while a similar slot I 9 is formed in the frame post I5.
A rod 2U extends between the frame posts I4 and I5 and is used as a pivot rod for the levers 2| and 22 which actuate the clamping members 23 and 24, respectively. Two guide rods 25 and 25 also extend between the posts I4 and I5 and have vtop surfaces which constitute a continuation of the surfaces I6 and I'I of the posts Ill and I5. The lower arcuate surfaces 21 and 28 of the guide rods 25 and 2'5 constitute guides over which the clamping members 23V and 24 slide. lThe guiderods 25 and 7.8 are separated from each other by a space zti through which the clamping vmembers 23ar`1d 24 extend.
The lever 2I which is similar in shape to the lever 22, has` a downwardly extending fingerengaged portion 3B, a sleeve 3| mounted on the rod 2.1i, an intermediate portion 32, a transverse portion extending through the slots I8 and I9,
a similar downwardly extending finger-engaged portion 36 and upper posts 31 provided with slots similar to the slots 35.
Arcuate resilient clamps 33 have ends engaging the levers 2 I and 22 and pressing them one against the other, so that the levers 2l and 22 are maintained by the clamps 33 in the operative position shown in Figure 1.
The lever 2l is connected and. movable along with a frame-like guard portion 4Q. A similar guard portion 4I is connected with the lever 22.
In the clamping position shown in Figure l, the guard portions ll'l and 4i form a substantially continuous blade-supporting surface, so that a bladef42 may be conveniently clamped between the guard portions 43 and 4I, and the clamping members 23 and 24.
A concave elongated nger-protecting element 43 extends along the outer edge of the guard portion 40 and is pivoted at 44 thereon. The member 43 hangs downwardly in the inoperative position of the razor shown in Figure 2. However, after the clamps 39 have moved the parts to the operative clamping position shown in Figure 1, a sharp edge of the blade 42 may be conveniently covered by the member 43 which is swung upwardly about its pivots 44. The opposite sharp edge of the blade 42 may be covered by a similar linger-protecting element 45 which is pivoted at 46 to the outer edge of the guard portion 4|.
The arcuate clamping members 23 and 24 are similar to each other in form and may be resilient either totally or in part. The members 23 and 24 which extend through the space 29 between the guides 25 and 26, have clamping edges 41 and 48, respectively. In the inoperative position shown in Figure 2, the clamping edges 41 and 48 are situated one next to the other, so that a blade 42 may be conveniently placed upon these edges which will extend through the central opening 49 of the blade. As soon as manual pressure upon the linger- engaging lever portions 30 and 36 is released, the pressure of the clamps 39 will move the levers 2| and 22 toward each other. The clamping member 23 is connected with the lever 2| by pins 50 which are integral with the member 23 and which extend through slots 35 provided in the posts 34 of the lever 2|. Pins which are integral with the clamping member 24, extend through similar slots provided in the posts 31 of the lever` 22. Thus a movement of the levers 2| and 22 toward each other will swing the clamping members 23 and 24 about the guides 25 and 26 and will move them through the central opening 49 of the blade 42 until the edges 41 and 48 of the clamping members will engage the blade 42 and press it firmly against the guard portions 40 and 4|, thereby clamping the blade.
The operation of the razor is apparent from the above description. The clamps 39 normally hold the parts of the razor in the operative clamping position shown in Figure 1. In order to move these parts into the inoperative position shown in Figure 2, the user merely presses the ngerengaged lever portions 30 and 36 toward each other. The levers 2| and 22 then swing away from each other while being guided in the slots I8 and I9, and the guard portions 40 and 4| move along with the levers 2| and 22. Since the clamping members 23 and 24 are connected with the levers 2| and 22 by the pins 50 and 5|, the
levers will cause the clamping members to swing about the guides 25 and 26 and to withdraw through the central opening 49 of the blade 42 and the space 29 into the interior of the frame 2 until the clamping members reach the position shown in Figure 2.
Then the used razor blade may be conveniently removed and replaced by a new one.
As soon as manual pressure upon the lever portions 30 and 36 is released, the clamps 39 will move the razor parts back to the clamping position shown in Figure 1.
Figures 4 to 6 show a concave elongated ringerproteoting element 60 which extends along the outer edge of a guard 6| of a razor. The element 60 has a curved spade-like portion 62 and a round tube-like portion 63 which is eccentrically mounted upon a pivot or rod 64. The portion 62 may be extended beyond the razor to facilitate the manipulation of the element 60. The pivot 64 extends through supporting portions 65 and 66 of the guard 6| and has a head 61 engaging the supporting portion 65. The opposite end of the pivot 64 is threaded and carries a nut 68, so that the pivot is held in place.
The portion 63 of the element 60 ts between the guard portions 65 and 66 and has outer surfaces 69 which approach or recede from the edge portion 10 of a razor blade 1| which is pressed -by a clamp 12 against the guard 6|.
Figure 5 shows the element 60 in its completely Withdrawn position, in which a space 13 is provided between the cutting edge 10 of the blade and a surface 14 of .the element 60. It is apparent that soap and hair particles are deposited upon the surface 14 during the shaving.
In the position shown in Figure 6, the surfaces 69 have been moved toward the edge 10, thereby closing the space between the cutting edge 10 and the element 60. Thus the angle at which the razor meets the skin of the shaver is changed. It is apparent that a closer shave is attained when the element 60 is in the position shown in Figure 5 than when it is in the position shown in Figure 6, if manual pressure remains about the same.
The element 60 is swung upwardly after the shaving until it is prevented from further movement in that direction by the engagement of the outer surfaces 6.9 with the adjacent edge of the guard 6|. At that time, the surfaces 14 which receive soap and hair particles during the shaving, are so exposed that they vcan be conveniently wiped to remove the soap and hair particles. In its upward position, the element 60 serves as an adequate protector of the cutting edge 10 to preserve the sharpness of that edge 10 and to prevent injury to any person grasping the razor.
It is apparent that the speciiic illustrations shown above have been Igiven by way of illustration and not by way of limitation, and that the structures above described are subject to wide variation and modification without departing from the scope or intent of the invention. All of such variations and modifications are to be included Within the scope of the present invention. l y
