Description
RAZOR BLADE FOR SAFETY RAZORS Filed April 12; 1955 Inventor J Z. W Kasm wsen Patented Nov. 26, 1935 UNITED STATES RAZOR BLADE FOR SAFETY RAZORS Edmund Wihlborg Rasmussen, Copenhagen,
Denmark Application April 12, 1933, Serial No. 665,805 In Denmark October 6, 1932 1 Claim.
The present invention relates to an improvement in razor blades for safety razors, and the distinguishing feature of the invention is that the blade, instead of having either three holes or a longitudinal slot, has two oblong holes one on either side of a central piece that is not stamped out and is attached to the blade merely by means of two narrow necks.
The circumstance that the central part of the blade is unhardened and has not been stamped out furnishes a guarantee that the blade has not previously been used. If the blade is to be used, the shaver bends the blade along a central axis, and the two quite narrow necks attaching the central piece to the blade will break causing the central piece tc drop out, after which the blade can be used in the ordinary manner. These necks 5 are formed between the widened, inner portions of the elongated holes 2 and 3.
The invention is illustrated on the drawing, on which 1 indicates the blade itself which is hardened and 2, 3 the two holes on either side of a central piece or seal 4, which is integral with the blade itself but not hardened.
It is to be noted that the width of the main part of each of the oblong holes is approximately that of the minor axis of the said central solid portion so that when both necks are broken the remaining portions will not extend beyond the edges of the holes 2. As a result no inconvenience will be occasioned when the blade is being applied.
Having now described my invention What I claim as new and desire to secure by Letters Patent is:
v A blade for safety razors the main portion of which is hardened, said blade portion having an unbroken peripheral edge with rounded ends, a central unhardened, oblong, solid seal with its major axis coinciding with the longitudinal axis of the blade, and two oblong holes arranged symmetrically along said axis, one on each side of said solid seal, the outer portions of said holes having substantially the same width as said seal, the inner hole portions being enlarged, narrow necks connecting the main portion and said solid seal between the enlarged portions of said oblong holes, the narrow necks being adapted to break by bending the blade along its central longitudinal axis and thus causing the severance of the solid seal from the body of the blade preparatory to its use.
