To all whom it may concern:
Be it known that I, Julius Bueno de Mesquita, a subject of the King of England, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Safety-Razors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in safety razors of the type employing wafer blades, and among the objects in view is the provision of means for firmly and efficiently retaining the blade in position during operation.
With this and further objects in view, as will in part be hereinafter stated and in part become obvious, the invention comprises certain novel constructions, combinations and arrangements of parts as herein set forth and claimed.
In the accompanying drawing,—
This application is a division of my co-pending application Serial No. 531,199, filed December 3, 1909.
Referring to the drawing by numerals,
An internally threaded sleeve
The operation, after the parts are assembled, is precisely the same as with any of the various types of safety razors and the assemblage of the blades with the holder is materially simplified while the firm, rigid retention is insured. When the cap is in the open position, as seen in
What I claim is:—
1. In a safety razor, the combination with a blade support, of a cap pivoted thereto and having a catch hook, and a plate fixed to the support and having a spring strip bent into a depending fold, the outer free end portion of said strip extending upwardly and being formed with a catch hook adapted to coöperate with the hook of the cap for detachably locking the cap in a closed position.
2. In a safety razor, the combination with a blade support, of a cap pivoted thereto and formed with a catch hook, a handle depending from said support, and a spring fixed at one end to the support and depending in a fold in rear of said handle and having its free end portion extending upwardly and formed with a catch hook adapted to coöperate with the hook of the cap for detachably locking the cap in a closed position.
3. A cap retaining spring for a safety razor frame, comprising an anchoring plate and a spring strip bent at an angle to the plate of substantially ninety degrees, the strip being bent back upon itself to form a fold, the return portion being bent into sinuous form and terminating in a hook.
4. In a safety razor, the combination, with a frame and a cap hinged to the frame and having a catch, of a plate anchored in the frame and tapered to form a spring strip, the strip being bent into a depending fold with the members of the fold spaced apart, the free end of the strip being formed with a catch disposed and adapted to interlock with the catch of cap, that lap of the fold having the catch being exposed for access for manual depression and formed with means to facilitate such depression.
5. In a safety razor, the combination, of a plate, a cap hinged thereto and having a catch, a plate fixed to the first-mentioned plate and having a recess, a plate in the recess and fixed to the first-mentioned plate, and a folded spring strip carried by the third mentioned plate and extending downwardly past a portion of the second-mentioned plate and then upwardly to a position beneath the cap, said strip terminating in a catch disposed and adapted to engage the first-mentioned catch for detachably locking the cap in its closed position.
In testimony whereof I affix my signature in presence of two witnesses.
Julius B. de Mesquita.
