SAFETY RAZOR Original Filed May 20, 1938 Fig;

Smaentor D-Ladrich CZaassen (Ittorneg Patented Aug. 13, 1940 UNITED STATES PATENT QFHQE SAFETY RAZOR Diedrich Claassen, Wellsburg, Iowa; Richard Claassen administrator of said Diedrich Claassen, deceased 2 Claims.

My invention relates to improvements in safety razors, and the object of my improvements is to provide an implement of this kind, disassemblable, and to receive and hold removably a flexible resilient blade between its clamping members, and with its elements relatively arranged for tiltable adjustments of the blade, and for securely locking thereof in either of its tilted adjustments.

Another and specific improvement is the provision of a transversely limitedly movable slide device mounted on the clamping means, having oppositely inclined terminations suitably pitched to be alternately engaged by the inner termination of a removably threaded handle, to in either position of opposite inclinations of the blade, be releasably interlocked between the handle end and the inner clamping member of the device in the most favorable inclined position of the blade for convenient and safe employment thereof in shaving.

My invention is illustrated in the details and the combination of its elements in the appended drawing, and as described and claimed in the specification and claims.

Fig. 1 is an elevation of my safety razor as assembled, and Fig. 2 is a like elevation thereof showing its parts connected but slightly separated from each other, both figures having parts broken away. Fig. 3 is an elevation of the outer clamping plate with its hinged stem. Fig. 4 is a plan view of a razor blade shaped to be associated with and. clamped between the clamping plates. Fig. 5 is an under plan representation of the outer clamping plate. Fig. 6 is an under plan of said blade as mounted on the outer clamping plate. Fig. 7 is an under plan view of the assembled clamping plates and blade therebetween, showing the transversely movable and oppositely inclined locking member on the under clamping plate.

The illustrations show a razor of the Well-known Gillette type, but it is to be understood that my improvements hereinafter described may, with any slight modification, be applied to other safety razors whose clamping parts are disassemblable.

The blade clamping means consists of the usual curvate outer end plate I and the under plate 8 conformable thereto but somewhat differently shaped. The plate I as shown in Fig. 3 end- Wise, has a medial or central depending lug 2 to which a depending threaded stem 4 is hinged, and the plate has a pair of elongated stops or lugs I on its underface medially, the plate having at each corner small angular depending lugs or stops Ia. In Fig. 6, the blade 5 of Fig. 4 is shown as mounted on the under face of the upper plate I, fitted between the stops Ia and having a medial longitudinal aperture 6 with terminal socket ends 5a, the ends of the aper- 6 ture at 5a being traversed by the longitudinal lugs I, and the hinged stem 4 traversing the middle part of the aperture 6.

The upper face medially of the under plate 8 is longitudinally tabular to seat the fiat but re- 10 silient blade 5 thereupon, as indicated in Fig. 2, and the stem 4 traverses a medial hole in said plate loosely as shown in Fig. 7. In the lower face of the under clamping plate 8 in its median line but crossing the same transversely is a shal- 15 10W depression 8b in which is seated a transverse body II for limited to and fro movements slidably thereacross. Stop plates 9 are secured by screws I0 on a longitudinal medial rib to loosely end engage their end parts medially of 20 the body II, the latter slidable to and fro therebetween in the socket 8b. This body II is longitudinally troughed with inwardly sloping end walls and a central opening as a loose bearing for the traversing stem 4. A handle I l has an in- 25 teriorly threaded socket Ma at its upper end with which the depending threaded termination of the stem 4 is meshed removably as shown in Figs. 1 and 2. The lower end of the body II is pitched at I Ia and Nb oppositely at each side 30 of the medial widened seat therein, the latter permitting the stem 4 to rock therein limitedly transversely to the clamping plates. The handle I4 has at its upper end an inwardly beveled widening at I4b, cupped to clear the medial 35 angles of the body I I when the handle is turned to clear them loosely while shifting the clamping members from one side to the other tiltably.

The lower clamping plate has the usual guard fingers 8a along its opposite longitudinal edges. The lugs I on the upper plate I are to be seated in medial longitudinal grooves 830'. in the rib-bed part 8d of the lower plate 8, to prevent relative displacements of the plates I and 8, rockingly.

Fig. 2 shows the different elements loosely con- 45 nected together and in medial alinement. In Fig. 1, the elements are engaged clampingly throughout for use. It will be understood, that with the elements loosely engaged as in Fig. 2, and the clamping plates tilted in either direction, 50 the handle I4 may be rotated progressively toengage the face Ila or III) in its path while drawing the clamping plates together. The plane of each face Ila, IIb so engaged being fiat, the clamping plates having been initially tilted 55 sidewise, the locking of the parts is positive, affording no possibility of relative displacements without a rotation of the handle oppositely to become disengaged from the body plane previously used. Possibility of an injury to the user by rocking or other relative displacements of the clamping members and blade is thus avoided.

I claim:

1. In a safety razor, an apertured blade, a pair of clamping plates therefor, one plate having an aperture, the other plate having a hinged terminally threaded stem loosely swingable transversely and traversing the apertures in the first plate, and in said blade, an apertured slide mounted for limited to and fro movements transversely of said one plate with said stem traversing its aperture to project therefrom and with the free end of said slide shaped with oppositely pitched faces, and a handle terminally interiorly threaded to be detachably mounted on said when the handle is rotated in one direction, the 3- plates having been previously tilted, the handle clampingly engages the abutting face of said pitched termination.

DIEDRICH CLAASSEN.
