'13-Claims. (01. -12), V

This-invention relates to safety razors and to the blades to be used in such razors. My invention contemplates, among other things the pro vision of 'simpleand eflicient means for properly and accurately positioning a blade in the holder therefor, as when the holder is assembled ready for shaving, which means allows the easy removal of the blade from the holder, when desired. V

Fig. 6 is a perspective view of one form of rigid blade adapted to be used in the holder.

Fig. '7 is a similar view of another form of a rigid blade.

Referring now to Figs. 1 to 3 inclusive, I have there shown a modified form of my improved razor wherein the blade may merely be laid on the guard member, the blade being automatically moved into shaving position by the clamping member on the operation. of the handle. In

' this form of my improved razor; the guard member terminates in the guard teeth 151 and is preferably though not necessarily made integral with the upper portion 152 of the'supporting shaft therefor. Said portion 152 is inserted into a suitable recess 153 in the hollow handle 154 and is normally urged upwardly and out of the handle by means of the compression spring 155 inserted into the recess 153' and surrounding the extension 156 of theguard supporting member. Said extension 156 passes through the handle 154 and is threaded at its lowermost end as at. 157

g for engagement with the rotatable nut 158.

; A suitable guideyslot as 159 is made in the member 156, said slot being engaged by the'pin 160 to prevent rotation of the member 156 relaon rotation of the nt 158 in the'proper direcmoves the support 156'and the guard 150 carriedthereby upwardlyrelatively to the handle .ever, of less fljhe guard member 159 is provided with a suitable upstanding projection 161 designed to pass through the slot 162 of the blade 163 and to position said blade longitudinally of the'guard. Said projection 161 is,'howblade may move transversely of the projection without said projectionleaving the slot', as will be more fully described hereinafter. The clamping member 165 is provided with a top and with depending sides 166 adapted to fit over the ends of the guard member. Depending from the. back 167 of the clamping member area pair of spaced arms 168 curved at their lower'ends 169 and piv-'- oted at their extremities 17.0 to the member 152 'by the insertion of said extremities into suitable width than the. slot 162 soithat the I hollows in'said member 152. The curved por- 'tions 169 act as cams cooperatingwith the bifurcated members 171 securedto the upper end of the handle 154.for that purpose.

It will be seen that after the ,blade 163 has member 150 and the parts are in apositionindiwhich the clamping member is pivoted, isdrawn downwardly relatively to the members l'llfwhlch thereby serve as pivots to swing the'clampin'g member toward closed position ,while they slide along the surface of the curved portions 169.: 'At

this, time, the bevelled or inclined portion112 of the top of the clamping member engages-the rear edge 173 ofthe blade and pushessaid bladeiorwardly, the projection 161 thereby moving in the slot 162, and the blade'moving forwardly until' its edge 1'73 engagesthe upstanding stops I174 at the ends of the'front edge of the guard member. 7

' Toremovehthe bade, the nut 15a is'turned in the oppositedireetion whereby the spring 1155 moves the clamping member upwardly relatively I to the handle and the members 171 by their en- 0 been inserted on the.,upper.surface of the guard gagement with the curved portions 169 swingthe ,45

clamping member in a the extremities 1'70 as a pivot.

It will be position as the clamping member is moved into place.

It will be understood that while I have shown various specific embodiments of my invention, I do not desire to limit myself thereto but intend to claim my invention as broadly as may be permitted by the state of the prior art and the scope of the appended claims.
