HOLDER FOR THE BLADES OF SHAVING APPARATUS.

Application filed February 28, 1925. Serial No. 12,404.

To alt who m it may come m:

Be it known that CARL Nir'rmonn, a citizen of the German Republic, residing at Breslau, Silesia, Germany, has invented certain new and useful Improvements in Holders for the Blades of Shaving Apparatus, of which the following is a specification.

This invention relates to a holder for the blades of shaving apparatus, when said blades have to be stropped and comprising holding studs in the one stationaryjaw which carries the handle and a second jaw which is hingedly connected with the stationary aw. The invention is characterized in that the hinge like connection between a removable cover plate which is not made of metal but preferably of celluloid and of the handle made of metal is secured without a hinge, by means of bevelled edges of the cover plate engaging with wedge shaped grooves of the handle.

\Vhen in the holders of known type the pivoted jaw is made of another cheaper material than metal, for instance of celluloid, the bore in this pivoted jaw designed to receive the pivot pin will Wear out after a very short time so that a blade is no longer securely held between the two jaws. According to the invention no hinges are used, the cover plate being secured in the position on the handle by the arrangement that its bevelled rear edge is inserted into a wedge shaped groove of the handle, its bevelled front edge being held by an undercut nose at the front end of the handle and being at the same time strongly pressed upon said handle so that it securely holds the blade to be stropped.

An embodiment of the invention is shown,

by way of example, on the accompanying drawing in which 1 is a plan view,

2 is a side elevation and Fig. 3 is a front elevation.

Fig. 4 shows in perspective view the several parts of the apparatus taken to pieces.

Fig. 5 illustrates the effect of the new manner of fixation of the pieces.

The handle 1 is preferably made of metal and half of its thickness is out off at the front part 2. The edge 3 is undulated and undercut in rearward direction so that it is of dovetailed shape. The undulated underrut portions form a transverse set or pair of longitudinal projecting segmental lugs having downwardly and inwardly inclined lower faces. bearing portions. In proximity of one of the longitudinal edges of the thin part 2 two holding studs 4, 4 for the razor blade are fixed. The razor blade 6 is placed 011 part 2 so that the studs 4 engage with the holes 5 in the blade. The handle 1 has at its front end a nose 7 which is undercut towards the surface of part 2 of the handle and has further an oblii ue inner surface, 18 (Fig. 5). The nose which is located at one corner of the reduced portion of'the handle is tapered transversely of the handle and its inner face is inclined downwardly and inwardly with respect to the nose being set diagonally by the transverse taper of the said nose. A cover plate 8 of the same length as the thin part 2 of handle 1 but of non-metallic material, for instance celluloid, is bevelled at its rear end 10 in opposite direction. as the undercut end 3 of handle 1 but is also bevelled at its front end 11 according to the undercut rear face of nose 7. The cover plate 8 has further notches 9, 9 in one of its longitudinal edges designed to engage over the studs 4, 4. The end recesses 10 are substantially segmental or semi-circular and have bottom walls which engage beneath the segmental lugs. The segmental lugs fit in the segmental recesses and form bearings or pivots on which the cover plate is adapted to swing later ally of the handle in the plane of the adj acent face of the reduced portion of the handle. v

The razor blade 6 is laid upon the thin part of the handle 1 (Fig. 4) so that the studs 4, 4 of the handle project through the corresponding holes 5, 5 of the blade. The end 10 of cover plate 8 is then inserted into the undercut edge 3 of the'ha-ndle as shown in Fi g. 5. The cover plate 8 is thus hingedly connected with the handle. The cover plate 8 is pushed from the position shown in Fig. 5 upwards so that its end 11 gets under the nose 7. Owing to the oblique face 18 of nose '7 the end 10 of the cover plate is forced into the undercut end 3 of the rear part of the handle 1 the bar 8 being at the same time tightly pressed on the surface of part 2 of the handle. As the nose 7 is also undercut the bevelled end 11 of cover plate 8 is also pressed strongly on the surface of part 2, so

These lugs form interlocking that the blade 6 is clamped by one manipulation between the cover plate 8 and the part 2 of the handle. As the studs 4 are at one longitudinal edge of the part 2 one half of the blade 6 is covered and only the half to be sharpened projects from the handle. The cross section of cover plate 8 and of the thin part 2 is of such shape, as shown in Fig.2, that, when the handle is being drawn flat along the razor strop the edge of the blade is pressed elastic-ally on the strop so that, when the blade is drawn along the strop it is correctly stropped,

I claim 1 1 A, holder for blades of shaving apparatus comprising in combination with blades having holes at themiddle, a handle having a reduced blade receiving portion provided at the inner end with; a transverse set of longitudinally disposed substantially segmental bcaringlugs undercut to present inclined lower races, a nose arranged at one corner of the outer end of the reduced portion, and

transversely tapered and undercut at the inner side to present an inclined face set diagonally by the taper of the nose, studs inonnted on the reduced portion of the handle at one ofthe longitudinal edges of the same and a highly resilient cover plate provided at one otitsedges with recesses to receive the said studs, said cover plate being provided at its inner end with substantially segmental recesses having bottom walls and conforming to the configuration of the seglnental lugs and engaged beneath the same, the segmental lugs forming pivots or bearings to permit the cover plate to swing transversely of the handle in the plane of theadjacent 'lace ot the reduced portion thereof, the outer end or the cover plate being frictionally engaged with the nose and maintained in such engagement by the rec siliency of'the cover plate.

In testimony whereof I aflix my signature.

CARL NITTINGER.
