SAFETY RAZOR HANDLE Filed Oct. 18. 1926 Patented Mar. 4, 1930' JAMES ALEX. DENIBY W'A'IT, OF LONDON, ENGLAND V SAFETY-RAZOR HANDLE Application filed October 18, 1926, Serial No.
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 becollapsed together and to be extended, some or all of the said parts, on
the exterior being roughened, ribbed, ser rated, 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 therewithand the telescoplc 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 Fig. 1 is an elevation of the handle in the extended position.
Fig. 2 is a similar view to Fig. 1 but in section. I Figs. 3 and 4 are similar views to Figs. 1
and 2 but in the collapsed condition.
Fig. 5 is a plan of Fig. 3 and Fig. 6 a modified form partly in section and with the handle in the collapsed position.
Fig. 7 is a similar view to Fig. 3 but showing another modification. i
In the drawings 7 are a number of tubular parts, star shaped in cross section (see Fig. 5) and slightly tapering from end to end. All the parts 7 are made with the same taper but to slipping. A further part 9 is provided of with successive parts made slightly smaller 142,444, and in Great Britain July 6, 1926.
the same length, taper and exterior shape as the parts 7 but formed with an internal thread 10. The part 9 comes within and co-operates with the smallest part 7.
In use the member 9 is attached to the cooperating part of the safety razor and the handle can be brought into the position shown at Figs. 1 and 2 for use. In this position it will be appreciated that the projectionsand reentrant angles of the star shaped section parts 7 form a good and certain grip for the user and prevent any slipping of the hand even if the handle is wet or soapy. Owing .to
hesection of the parts 7 and 9, moreover, relative rotationis prevented and this still further increases the security during the use of the razor. When the razor is not in use the handle is readily collapsed into the position shown in Figs. 3 and 4: for transport or storage in small space and may remain attached to or detached from the razor proper.
Means may be provided in some cases for retaining the parts in the collapsed position; an example of such a means is shown in Fig. 6 where the closure or base 8 is formed or provided with a split pin or projection 11 adapted to springily engage with a plain portion 12 of the bore of the part 9 when in the collapsed position to hold the parts in this position.
In Fig. 7 piercings, slots, punchings or holes 14 are shown to increase the grip. These can be of any shape and can alone be provided for the purpose or in combination with any other means such as corners, edges, serrations or otherwise.
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 suit- 9 able 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 13 Fig. 2 may come on top of the top joint of the handle to which it may be affixed.
The closure, such as 8, for the end of the outermost telescopic part, may in some cases be made detachable for cleaning or other purposes and may be frilled or slotted for draining or may be entirely omitted.
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 fiat 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 thesurfaces have corners or edgesthe e knurling or other roughening may also be added.
What I. claim and desire to secure by Letters- Patent in the United States of America 1s:
A safety razor handle comprising a plurality of frustro-pyramidal members telescopically related to one anotherQthe smaller end of each member being of less size ontheinterior 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 1igiember to the larger end of the largest mem .In witness whereof I. alfix my signature.
