This invention relates to safety razors and has for its object to provide a collapsible handle for such devices and to form or provide the exterior thereof with means for increasing the grip of the user thereon.
According to the invention safety razor handles are made from a number of telescopic parts adapted to be collapsed together and to be extended, some or all of the said parts, on the exterior being roughened, ribbed, serrated, pierced or slotted a portion of their length, shaped or otherwise formed with a “grip.” The telescopic part coming at one end is formed or adapted to be detachably or otherwise attached to the safety razor proper or a part in connection therewith and the telescopic parts are preferably formed or provided with means to prevent relative rotation.
In order that the invention may be better understood it will now be described with reference to the accompanying drawing which shows to a scale of twice full size one constructional form of the invention and in which :—

Means may be provided in some cases for retaining the parts in the collapsed position; an example of such a means is shown in
Although a screw engagement has been indicated in the drawings for attaching the collapsible handle to the razor proper (that is to the blade holder guard or other suitable part thereof) other attaching means of any desired construction may be employed which may be of a detachable or fixed nature.
In some cases a washer such as indicated at
The closure, such as
The shape in cross section of the telescopic parts may be as desired for instance that of any regular or irregular polygon with or without reentrant angles, it may also be circular elliptical or of other curved shape alone or with straight portions to form flat faces. Where the surfaces on the exterior are without corners or edges these surfaces are knurled, serrated, ribbed, grooved, pierced, slotted, punched or otherwise roughened and where the surfaces have corners or edges the knurling or other roughening may also be added.
What I claim and desire to secure by Letters Patent in the United States of America is—
A safety razor handle comprising a plurality of frustro-pyramidal members telescopically related to one another, the smaller end of each member being of less size on the interior than the larger end of the next succeeding smaller member, on the exterior, means in the smallest member for the attachment of a blade holder to the handle and a closure member to the larger end of the largest member.
In witness whereof I affix my signature.
