Specification of Letters Patent.

Patented June 4, 1907.

Application filed April 4,1907- Serial No. 366,448.

To all whom, it Wild/Z] concern: i p Be it known that I, LYMAN'H. 001313, a

citizen of the United States, residing at Fitchburg, inthe county of Worcester and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Safety-Razors, of which. the follow-. mg is a specification accompanied-by draw-- removed.- Fig. 3 is a central vertical sectional view of the same; Fig. 4 is a'sectional view on line 4-4 Fig 2, but with the blade in position. Fig. 5 1s a view of a modified form of blade. w 7

Similar reference letters and figures refer to similar parts in the different views. v

My invention relates to an improved form of safety razor in which I combine ease of in,- sertion and attachment of the blade with security in such attachment, and it consists in the construction and arrangement of parts as hereinafter describedand pointed .out in the annexed claims.

Referring to theaccompanying drawin s, 1 is the head of thesafety razor provirfed. with a handle 2, detachably secured in any suitablemanner'to the head, in thepresentv instance by a screw '3tinserted'in a screw threaded hole ,4 in the handle 2. ,The he'ad. 1 comprises a leaf 5 adapted to support the blade and upon which the blade is held by the blade.

the spring arms 6,-6, with the under side of their ends 7, 7, substantiallyin the plane of *the leaf 5, which is provided with openings 7 7 to provide a clear 8, 8, beneath the ends The leaf. 5 is provided with arearward extension 9 between the arms 6, 6, to serve as a handle by which the leaf 5 may be slightly depressed in order to allow the insertion of The leaf 5' is also provided with lugs. 10, 10, arranged to contactwith the cars 11, 11, on the razor blade, thereby insuring the correct position of the blade on the leaf 5. Upon the insertion of the blade the extension 9 is released and the blade is firmly pinched between the leaf 5 and the arms 6, v6, and,

firmly held by the elasticity of the arms ,and' leaf." I

Thehead '1, as shown, consists of a-single piece of sheet metal out inthe required shape.

and bent' downward and rearward at the front edge of the leaf 5 to receive the handle, then fupward andforward with the arms 6, 6, turned downward overthe rear edge of the leaf 5 the extension 9. is bentinto proper leaf 5'for the insertion ofthe blade. vAt the front of" the leaf 5 are-slots .12 -e'xtending.

1 across the acute angled bend 13, and beneath the cutting edge of the blade to {form 'the curved guards 14;.- I donot confinemyself,

however, to the s ecificde/tails offconstruc tion shown as, so ar asI am aware,lthe emr ployment .of a blade supportingleaf and overlapping arms between which the blade is pinched by elasticity of the arms, or table,

1 or both, is broadly new.

In Fig. 5 I have shown a modifiedform of leaf 5. "Projecting from the rearedge of the form to serve as a thumbpiece to depress the bladeprovided with" two cutting edges 15, 15, which may be used with my safety razor.

This blade is provided with two airs ofears 11, 11,. arranged to inclose the ugs 10, 1:0,, and hold'the blade in position, with-either Olf;

its-cutting edges at the front. The openings 8, 8, in the leaf 5 are larger than the opposing ends 7,7, of the arms 6, '6, 'andprovidea 'clear space around the ends7, 7', to facilitate the cleansing of the head when the blade is removed.

' Iclaim, I razor, a head provided with a spring leaf or the support. ofa cutting. blade, an overlapping arm having its free end substantially in the plane of the leaf, and means for separating said leaf and said. arm for the insertion of a blade between them. 2. In a safet razor, a head provided with a spring leaf" or the support of'a cutting blade, a spring arm in contact with the supporting surface of said leaf, and means for depressing said 'leafto provide for the insertion of a blade. 1 r
