Application IellMay 31, 1910. Serial No. 564,299.

This invention relates to a safety razor of the type in which the razor blade consists of .two thin flexible steel plates held together to form a single blade which is pressed between a support and a shield.

` According to this invention, the handle of the apparatus is formed of two doublearrned levers pivotally connected together and preferably controlled by a spring. The ends of this handle, which are turned toward the shield in the position of use, press said shield against the blade and thus clamp the said blade firmly in the cutting position between the shield and support. lt is advantageous to combine with the levers a hook -or the like, in order that the shield and support may be more iirmly grasped and in order after opening the levers that the loose parts will be still attached to the handle. Upon the ends of the levers there is placed a cap, clamp or the like which holds the levers fast in the position of use -in opposition to the action of a spring placed between them but which automatically slips ofi'I the ends of the levers and releases them when the latter are approached close to one another. In order to facilitate the adjustment of the cutting edges between the angular support and the shield, the plates constituting the razor blade are pivotally connected together parallel to their edges.

Y Referring to the accompanying drawing forming a part of this specification wherein the invention is illustrated in two modifications z-Figure 1 is a side` view of the invention partially in elevation and partially in section; Fig. 2 is an end view partly in section of the parts shown in Fig. l; Fig. 3 is a plan view; Fig. 4 illustrates the razor blade detached; Fig. 5 shows amodification of the device partially in elevation and partially in section; Fig. 6 is an end viewof the parts shown in Fig. 5 partially in elevation and partially in section; Fig. 7 shows the handle aloneA in the open position; and Fig. 8 shows a furth'er modification of the razor-blade.

The razor blade of this mechanism is j formed of two thin hardened steel plates a constituting a single blade andv possessing two cutting edges, which plates are secured g in hinged holders b' placed parallel to the cutting edges c as best shown 1n Fig. 4. The vblade and holder is clamped fast in the usual Ina-nner between a support Z and a shield f, which .parts are formedA with an angle and possess fiat clamping surfaces, between which the razor blade in consequence of the hinged connect-ion of its two plates lits closely (Fig. 3). The shield f is provided with teeth g in the usual manner, against which the cutting edges of the blade press after it is firmly clamped in place, and I over which they slightly project as indicated in Figs. l and 2. The support- Z has a projection 7L which passes through a perforation k in the razor blade and a corre' spending perforation in the shield, in order that the operator ma easily eect the cor;I rect adjustment of t e parts. The projection Zi has a slot i in which a hook j attached to the handle engages and by which the hook, the support, the 'razor blade and the shield are suspended and held together even when the clamping action of the handle of the device is not 1n action.

The handle consists of two double armed levers, having long armed handle portions k Z, and the short armed clamping portion k Z, Fig. 1,l which are further provided with the grooved extreme end portions k2 Z2 into which fit the projections of the shields f as shown. It will thus be seen that when the parts are in the position shown 1n Fig. 1, the lsaid short armsare caused to press firmly against the shield and thereby serve to clamp the blade between said shleld and said support d. The shield f has guide ribs which engage in a groove on the ends of the shorter arms of the levers 7c Z so that levers. If the levers k Z are pressed flat -against one another and the spring, then the cap m slides olf from the ends of the levers under the influence of, a spring indicated in dotted lines in Fig. 1, and the levers when released, will automatically return to the open position (Fig. 7).

The modifications illustrated in Figs.

to 8 differ from the structure above declamp the razor blade. The remaining construction of the handle remains the same yas that above described.

Having now. particularly described rand ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In a'safety razor, the combination of aishield; a support; a blade located between said shield and support; a handle comprising two pivoted levers whose ends are `adapted to wedge against said. shield; and

connections between said levers and sup'- port adapted under the wedging action of said levers to cause said bladeto be firmly clampedV between said shield and support, substantially as described.

2.- In a safety razor, the combination of a shield; a support; a blade located between said shield and support; a handle comprising two pivoted levers whose ends are adapted to wedge against said shield, and a hook between said levers. and support adapted under. the wedging action of said levers to4 cause said blade to be firmly clamped between said shield and support, substantially as described.

3. In a safety razor, the combination of a shield; a support; a blade located between said shield and support; a handle comprising two pivoted levers whose ends are adapted to wedge vagainst said shield; a hook between said levers and. y support adapted under the wedging action of said levers to cause said blade. to be firmly clamped between said shield and support; and means for holding said levers in their closed positions, substantially as described.

4. In a safety razor, the combination of a shield; a support; a blade located between said shield and support; a handle comprising two pivoted levers whose ends are adapted to wedge against said shield; a hook between said levers and support `adapted under the wedging action of said levers to cause said blade to be lirmly clamped between said shield and support; and means comprising a spring actuated cap adapted to hold said levers in their closed positions, substantially-as described.

5. A'safety razor comprising a shield; a

support; a hinged holder; and a blade held in said holder and located between said shield and support7 substantially as described.

6. A safety razor comprising a shield; a support having a projection.; a hinged holder located between said shield and support and having a perforation through which said projection may pass; a plurality of blades carried by said holder; and means associated with said holder for pivotally connecting Said blades, substantially asdescribed.

In testimonyv whereof I have aiixed my signature in presence of two witnesses.
