To all whom it may concern:
Be it known that I, Jules Emile Leresche, manufacturer, a citizen of the Republic of France, and a resident of St. Julien-du-Sault, France, have invented new and useful Improvements in Razors with Removable Blades, of which the following is a specification.
This invention relates to razors having removable blades.
According to my invention I secure the blade into the groove of the blade-carrier by means of a lever mounted upon the blade-carrier and the head of which is so arranged as to act in the manner of a cam or eccentric. This head, together with the blade-carrier and the back of the blade, is so formed that by depressing the lever for fixing the blade the said lever exercises two actions simultaneously upon the blade—viz., on the one hand it draws the blade into the groove and retains it there and on the other hand it pushes it longitudinally, so causing it to press strongly against the abutment formed for this purpose in the carrier at a suitable part. Thus the blade is retained in and securely fixed to the blade-carrier at two independent points—viz., at the head of the lever and at the abutment of the carrier. By lifting up the lever the head thereof presses against the back of the blade and in this manner forces the same out of the groove in the carrier, whereby the removing of the blade is facilitated in case it sticks or is otherwise retained in the groove—say by rust, or through the deformation of the parts, or from any cause whatever.
My invention will be readily understood from the accompanying drawings, in which—
The same letters of reference designate the same parts in all the figures.
In order to fix the blade in position, it suffices to place it as shown at
It will be noticed that in the form shown at
I would remark that the fixing of the blade
As to the disposition of the abutment, this may be varied to a large extent. Thus the abutment may be formed as shown at
The lever may be inverted—that is to say, it may be disposed—so as to move down toward the razor-handle instead of turning toward the front end of the blade. It then acts to force the blade against an abutment arranged at a point of the blade-carrier between the lever and the end of the blade—for example, near the front end of the blade-carrier.
A razor comprising a blade-carrier grooved to receive the blade, a locking-lever pivotally connected with said carrier and provided with a cam-head, an abutment on the carrier, and a removable blade provided with a projection on its back having a cam-face engaged by the cam-head of the aforesaid locking-lever, and a seat-face engaging the abutment on the carrier, the cam-head of said lever acting to draw the blade into the carrier-groove and force the seat-face of said blade against and hold it to said abutment, substantially as set forth.
In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 31st day of May, 1899.
Jules Emile Leresche.
