SAFETY-RAZOR.

Specification of Letters Patent.

Patented Aug. 16, 1910.

Application filed .Tune 22, 1909. Serial No. 503,619.

To all whom it may concern:

Be it known that I, GEORGE W. Connow, a citizen of the United States, and resident of New York, in the county of New York and State of New York, have invented "certain new and useful Improvements in Safet -Razors, of which the following is a speci cation.

This invention relates to improvements in safety razors.

In the drawings: Fi re 1 is a top View of the blade holder an guard. Fig. 2 is a side view of the blade holder, uard and handle. Fig. 3 is a front edge View of the blade clamp, detached. Fig. 4 is a side edge view of the blade holder, detached. Fig. 5 is a side view of the handle,-detached. Fig.

6 is a top view of the blade holder, detached.

ness. The ears 12 12 forming thepivoted connection between the holder and handle, are partly severed from, and turned down on the same piece which forms the body of the holder. Struck up from the same piece to protrude above the body of the holder are the dogs -13 13, the heads 14 -14 whereof, are rounded in the forms of thin pads adapted to extend into round perforations formed in the razor blades. The shanks of these dogs are ex tended backward away from the guard edge 15- of the holder. The disposition of the shanks forms resisting members to receive and hold the blade on the holder, while the clamp 11 is being adjusted. Set out from the sides of the holder are the lugs -16 -16- against which the clamping arms '17 -l7-- of the clamp impinge and are arrested. The blade holder -10- is hingedly mounted on the handle -18 at 19- by the rivet headed in -20.- To limit the backward throw 0 the holder -10 the handle has formed thereon the extension -21- against which the holder strikes and rests. The upper surface of the holder 10- is curved transversely to its longest dimension, it being the desire to hold the blade in a rigid bended shape on said holder. As stated, the blade is pcrforated to receivethe pads l4 l4-.

To maintain the blade --Z- on the holder, and to bend it on the same, I have provided the clamp -11--. The clamp is curved to conform substantially to the holder 10- and is hingedly mounted at 22 upon the handle -18 the hinge being formed by a rivet headed pin 24.-. The arms 17 are formed as shown, and are provided with the flat bent lugs23 -23 whereby the arms and clamp are forced into position. The hinge mountings -20 and -'22- are separated to produce a longer radius for the movement of the clamp .11- than that produced by the shorter ears -12- -12 by which the movement of the holder --10- is regulated. The distance of the hinge at 22 from the body of the clamp -11-- is less than the distance from the said hinge -22- to the upper surface of the holder 10- when measured through the hinge at -19---. This causes the clamp to be drawn upon to bear against the upper surface of the holder l0 to hold any interposed blade thereon. It is by this eccentric movement of the holder and clamp that they are drawn together as the arms 17-- 17- and the ears-12- -12 approach alinement.

In the operation of inserting or removing a blade from the holder, the following acts are performed: The clamp '17- and the holder-10 are forced forward. to the positions shown in dotted lines at Fi 5 of drawings. The blade Z is now a justed on the holder --10- in such manner that the pads -14 14;- are held in the perforationsformed in the blade. The clamp 11- is then swung back until it strikes upon the blade on the holder -10-. From this point the clamp and holder move in unison, assuming the final position as shown in Fig. 1 and Fig. 2 of drawings. Tn this final position the lines of the ears 12 12- and the arms -l7 l7' fromthe hinge mountings l9 and --22 coincide, clamping the blade firmly in position and being locked against disadjustment.

The blade which it is desired to use is the usual two-edgedblade. When employing such, the blade is reversed in the holder during use. When it is desired to use the straight single edged blade, the form of holder employed is that shown at Fig. 9 of drawings wherein the dogs 13 -13 are dispensed with. The back -25- is upturned at the rear edge, of the holder I Against this'back 25 the blade is' adjusted and held when the clamp 11 is swung into position.

Having thus described this invention, what is claimed is; v

1. A safety razor comprising a handle having a blade holder hingedly mounted thereon, at one end thereof, said holder being curved in the direction of the line of cut; a thin flexible razor blade and a clamp convexly curved transversely to its longest dimension, hinged to the said handle at a point thereon below the hinge of the blade holder thereon so that the clamp is adapted to move over the blade holder eccentrically to the movement of the blade'holder.

, 2. A safety razor comprising a handle having a blade holder-hingedly mounted thereon atone end thereof, said holder be ing curved in' the direction of the line of .cut and having hinge wings formed inteone end' thereof, havin a blade holder with sto 5 formed integral y therefrom at the en s and back thereof, and a clamp member each hingedly mounted on said handle the one above theother at one end thereof by hinge arms of different lengths so that the clamp is adapted to move over the razor blade member positioned on the blade holder, eccentrically to the movement of the blade holder as they swing to the clamping position against stops. 7

4. A safet razor. comprising a handle having a bla e holder member and a clamp member each hingedly mounted thereon, at one end thereof, by hinge arms of difi'erent lengths, the pivots of sald arms separated a distance greater than the difference in the length of said hinge arms to draw the said members together as they swing to the clamp-ing position, thereby holding clamped a thin flexlble razor blade firmly in position for use.
