SHARPENER FOR RAZOR-BLADES.

Specification of Letters Patent.

Patented Sept. 23, 1919.

Application filed January 27, 1919. Serial No. 273,270.

. it consists in certain peculiarities of the construction, novel arrangement and operation of the various parts thereof,-as Wlll be hereinafter more fully set forth and specifically claimed.

The principal object of the invention is to provide a manually held and manipulated sharpener for razor blades, particularly detachable blades, such as are used in many safety razors, which shall be foldable and compact in form so as to be conveniently carried in the pocket if desired, simple and inexpensive inconstruction, strong, durable and elficient in operation. Another object is to provide a sharpener of the above named general character, wherein the arrangement, construction and the character of the material of the parts thereof is such as to ,cause the sharpening sheet or member, when the device is in use, to conform to the contour of the-balm of the hand on which the device is mounted, to the end, that substantially a plane or a more or less curved surface of the sharpening member may be presented to the blade in the operation of sharpening the same. Still another object is to provide means for detachably mounting the sharpening member on the body or supporting member of the device, in order that it may be readily removed when worn or acciden tally cut, and may be replaced by a new one. Other objects and advantages of the invention will be disclosed in the foregoing explanation and description,

In the accompanying drawing which serves to illustrate an embodiment of the invention Figure l is a perspective view showing the sharpener in operative position on one hand of the user and the safety razor blade held in the other hand in about the position it will occupy in the operation of sharpening the same:

Fig. 2 is a detached rear perspective view of the sharpener;

' taken on line 3-3 of Fig. 2, looking in the directionindicated by the arrows, and

Fig. 4 1s a perspective view of a fragment of the sharpener showing a means for de- .tachably securing the sharpening member or sheet to the supporting member or body of the sharpener at the corners thereof.

Like numerals of reference refer to corresponding parts throughout the different views of the drawing. The reference numeral 5 designates one of the hands, usually the left hand, of the user of the device, on

the palm of which the bod or supporting member 6 of the sharpener is mounted and held 1n position thereon by means of a strap 'or piece of tape 7 located transversely with and at about the middle of the member 6, and said strap has its ends secured to the edges of the member 6 by being stitched thereon, or in any other suitable way. The member 6 may be made of any suitable size, form and material, but by preference is substantially rectangular in shape and of sufficient size to almost entirely cover the palm and fingers of the hand. I In order to render the body or supporting member 6 of sufficient rigiditv or stiffness to maintain its position closely against the hand and yet to allow it.to conform to the contour thereof said member is preferably made of pliable material, such as leather, leatherette or the like, and may have its inner surface lined with rep-cloth 8, or some suitable rough material. At each of its corners the body or supportin member 6 is provided on its inner sur ace with a socket 9 to engage button heads 10, which are secured on the inner surface of the sharpening member 11, and near each of its corners. The sockets 9 and the button heads 10 provide fasteners for detachably connecting the sharpening mem- :ber 11 to the body or supporting member at the corners thereof, and said fasteners may be of the ordinaryand well-known glove fastener type. Near one of its ends the member 6 is provided with a gromet 12, by means'of which it can be hung up, when not in use, on a nail or other projection. The sharpening member or sheet is of substantially the same size and shape as the supporting member or body 6, and is by preference made of linen huck, which as is wellknown has a cellular or rough surface. By preference the sharpening member 11 is formed of two plies 12 and 13 (see Fig. 3 of the drawing), that is, said member is made of a single piece folded back upon itself at its lower edge, and has its end edges and its upper edges secured together by stitches 14. By this arrangement the lower edge of the sharpening member 11, WlllCll -W1ll be subjected to more or less friction from the razor'blades and the hand 15 in which the same are held in the operation of sharpening them, will be prevented from ravehng. As shown in Fig. 1 of the drawing, when the parts have'been assembled as above set forth and the sharpener is mounted on the palm of one hand, the razor blade may be gripped between the thumb and fore finger of the other hand and placed slantingly on the sharpening member 11 near one end thereof, when it can be slid along the surface of the sharpening member to near the other end of the same, when, by proper manipulation, the blade 16 can be' turned so as to bring its opposite surface in contact with the sharpening member and moved back thereon to near the opposite end thereof. This operation may be repeated as often as is deemed necessary, and when one edge of the blade has been sufiiciently sharpened, the other edge thereof can be presented in a similar manner to the sharpening member, and the movement above described repeated. By this operation it is apparent that the device may be held in substantially a flat plane,-

or, if desired, an inward curvature can be given to the device by bending the fingers of the hand on which it is mounted slightly inwardly. By this close fitting arrangement of the parts of the sharpener to the hand on which'it is mounted, it is manifest that theedges of the blades will be acted on by the sharpening material, which is flexible, in such a manner as to quickly, thoroughly and uniformly shar en its edges. The body or supportin mem er 6 is by preference of greater thic ess and rigidity than the sharpening member 11, for the purpose of holding the latter in such a way as to prevent it wrinkling when the supporting hand is curved, and also for the purpose of providing a continuous surface against which the blades may actin their movements over the same. The edges of the body or supporting member 6 may be bordered with a suitable binding 17 to add attractiveness thereto, as well as to hold the lining 8, when the same is employed, in position thereon.

the movement of the blades over the sharpening member.

After the device has been used, it is evident that it can 'be'readily removed from the hand and folded into compact form, or, if desired, can be suspended by means of the gromet on a nail or' other suitable projection.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is- 1. A sharpener for. razor blades, consisting of a supporting member having means to fasten it on a hand and to sustain it on the palm thereof, a sharpening member mounted on the. supporting member, said members having near their corners 00- acting fastening means detachablysecuring them together.

. 2. A sharpener for razor blades, consisting of a flexible supporting member having means to fastenit on a hand and to sustain it on the palm thereof, and a flexible sharpening member detachably mounted on the supporting member.

3. A sharpener for razor blades, consisting of a flexible supporting member having its inner surface roughened, a strap secured at its ends to said member and extended across the outer surface thereof at about its middle, and a sharpening member mounted on the'inner face of the supporting member and consisting of a sheet of fabric.

4. A sharpener for razor blades, consisting of a flexible supporting member, a strap secured at its ends to said member and extended across the outer surface v thereof at about its middle, and a sharpening member detachably mounted on the inner face of the supporting member and consisting of a sheet of fabric, the-said supporting member being of greater thickness and possessing 105 greater rigidity than the sharpening mem-
