SAFETY RAZOR Filed Aug. 1, 1951 ge' 'l l Patented Aug. 30, 1932 j Y Application led August'vl, l'

This invention relates to an improved safe# ty razor, the object of the invention being primarily to have the clamp plate, guard plate and handle connected together when the` razor blade is 'removedfrom thesafety;

razor as well as when itis positioned therein, so that the blade, can be removed andthe other parts will be still connected together,

and can be washed while-connected together.V

if The inventionconsists in the combination and arrangement ofv parts set'forth .inthe following specificationl and particularly as pointed out in the claim. Y Y

Referring to the drawing'z.- l5 Fig. 1 is a plan view of a safety razor embodying my invention.l

Fig. 2 is aside elevation thereof.;`

Fig. 3 is a front elevation of thesafety razor. 5" Fig. 4 1s bular handle a clamp .screw 12 is rotatably mounted, the sametbeing shouldered at its!

moved away from the guard plate by the Y linger or thumb of the user and the clamp j plate can be also tipped at an angle, as aforej said, the user inserting his thumb( or linger 'through the recess 28 in the guard plate in order to press the razor blade and `clamp Y plate away from the guard plate.
