My invention relates to improvements in safety razor holding devices and deals particularly with the handle portion thereof, or the element on the device which is grasped by the user in the operation of shaving.
A razor equipped with the conventional type of straight handle is somewhat awkward to manipulate when shaving certain portions of the body—particularly so in connection with shaving the arm-pits and parts of the face along the neck line.
The primary object of the present invention is to supply facilities in the handle portion of razor devices whereby the instrument may be more firmly and conveniently held in the user's hand while shaving, the structural improvement residing in the incorporation of a ring or band shape finger-hold by means of which the razor can be manipulated so that all the different strokes required in shaving the face or other parts of the body can be made without changing or re-arranging the three-point grasp which this particular form or shape of holding element provides.
The grasp of the razor is made so effectively that even when the fingers have been smeared with soap or shaving cream the hold on the instrument is in no way affected. Furthermore, the finger-hold can be positioned and secured on the guard element so that any one of various angles of presentment of the blade to the user's face can be had, and after once being set in the desired position this relation can be more accurately maintained than is possible with the ordinary round handle affair.
In the accompanying drawing I have disclosed certain embodiments of my invention which, at the present time, I consider preferable to other possible forms in which the invention might be carried out.
In the drawing,—

Referring to the drawing,
The finger-hold
If the free ends are left disjoined, as in
The band has a hole
In the
The nut
The outward pressure of the blade when flexed by the back member
The finger-hold band
The depression in the bumped portion
I may elect to perforate the wall of the band with holes
When the finger-hold is disposed on the guard as shown in
In re-arranging the finger-hold by unloosening the screw it necessarily disturbs the adjustment of the blade
The grasp of a shaving instrument equipped with my improved finger-hold attachment is much more natural, secure and convenient than is the case with the ordinary small round handle; it is cheaper to construct, can be packed into a smaller space and is considerably lighter in weight. The screw thread on the member
The embodiment above disclosed is of course primarily illustrative and my invention is, obviously, capable of interpretation in a wide variety of structures.
What I claim is:
1. A safety razor holding device comprising in combination with a guard, a back member and a screw-threaded stud extending from said back member to and through said guard, a finger-engaging band of generally circular form rotatively mounted on said guard, an inwardly disposed depression in the wall of said band, an aperture in the bottom of said depression, a nut, adaptable of screw-threaded engagement with said stud, disposed within said band, a reduced portion on said nut operable in said aperture, and means to hold said nut against displacement from said band when disengaged from said stud.
2. A safety razor comprising in combination with the guard, having a central hole therethrough, a back member, a razor blade interposed between the said guard and said back member, a threaded stud integral with said back member and extending therefrom to and through said guard, of a finger-engaging band, having a hole through its wall, disposed on and adapted to thrust against said guard, a nut, having a reduced portion operable in said hole, adapted to engage said stud and thrust on the inside of said band, said nut adapted to secure said band in any one of a plurality of pre-determined angular positions on and with respect to said guard simultaneously with deflecting said blade to any desired degree, and means to hold said nut against displacement from said band.
In testimony whereof I affix my signature.
