To all whom it may concern:
Be it known that I, Otto Kampfe, a citizen of the United States, residing in the borough of Brooklyn, in the county of Kings, city and State of New York, have invented an Improvement in Safety-Razors, of which the following is a specification.
My invention is designed as an improvement upon the safety razors shown and described in applications for Letters Patent filed by me, the one under date of October 2, 1906, Serial #337.152, and the other under date of July 20, 1907, Serial #384,798, with the object of freely introducing a thin flexible blade into the curved holder of a safety razor and removing the same therefrom in a normally flat condition and so removing all liability of cutting the fingers in handling the blade.
In carrying out my invention, I provide the body member with openings or bayonet slots which are as deep as is required for the extreme movement of the guard-comb between its full open position with the thin normally flat blade inserted freely in position and its extreme position under pressure with the flexible blade bent or flexed and ready for use. The construction of the safety razor holder is substantially the same as described in my before-named applications.
In the drawing,
The body member
In the back and at the upper edge of the body member I provide apertures in the form of bayonet slots
I claim as my invention:
1. In a safety razor, the combination with a thin normally flat removable and resilient blade, of a body member adapted to receive and having edges to extend over and engage all edges except the cutting edge of the blade, a longitudinally curved guard comb coming against the under or opposite side of the blade to flex the same and said guard comb adapted for a uniform falling and rising movement equally away from all edges upon its release, providing for the ready insertion of the thin removable blade in its normally flat condition, said body member being provided with spaced apart vertically disposed slots of greater length than the extent of movement necessarily required for the guard comb and projecting members of the guard comb passing through such slots and movable therein and constructed for engagement therewith to prevent the accidental separation of the guard comb from the body, and means for applying tension to move the guard comb and blade bodily outward against the said edges of the body member and flex the blade.
2. In a safety razor, a longitudinally curved guard comb having hook-shaped lugs, a body member receiving the comb and having curved engaging surfaces, and having bayonet slots which in depth are placed at right angles to the plane of the lugs and receive said lugs, a thin normally flat removable resilient blade placed freely between said guard-comb and body member in its normally flat condition and means for moving the comb and blade bodily and so applying tension to bend and flex the blade and clamp the same ready for use between said parts, the release of which clamping means permits the resilient blade to straighten or return to its normally flat condition and in so doing move the guard comb.
Signed by me this 29th day of Sept. 1909.
