To all whom it may concern:
Be it known that I, John F. O'Malley, a citizen of the United States, and a resident of Mamaroneck, in the county of Westchester and State of New York, have invented a new and Improved Safety Razor, of which the following is a full, clear, and exact description.
This invention has relation to safety razors and has particular reference to an improvement in safety razors of the double edged fiexible blade type.
The outstanding object of the present invention chiefly resides in the construction of the blade-holding means, several parts of which are permanently connected together in order to facilitate the application and removal of the blade and to prevent dropping or loss of the elements as is the case with holders in which the parts are separable.
As a further object the invention contemplates in a safety razor of the character set forth a blade and blade holding means in which adjustments to vary the flexing of the blade for a coarse or fine shave is not disturbed during the use of the razor by the ordinary handling of the same.
The invention furthermore contemplates a safety razor which is comparatively simple in its construction, inexpensive to manufacture and produce, and which is highly efficient in its purpose.
With the above recited and other objects in view, the invention resides in the novel construction set forth in the following specification, particularly pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that the right is reserved to embodiments other than those actually illustrated herein to the full extent indicated by the general meaning of the terms in which the claims are expressed.
In the drawings—
Referring to the drawings by characters of reference,
In use and operation of the device the nut
1. A safety razor including a flexible double edged blade and holding and clamping means therefor comprising a handle, a guard member rigidly attached thereto and a head having pivotal and slidable connection with the handle to permit of lateral movement in addition to movement in a line parallel to the axis of the handle whereby to effect clamping and unclamping of the blade to associate and disassociate the same with the holding and clamping means.
2. A safety razor including a flexible double edged blade and a holding and clamping means therefor, said means comprising a handle, a guard member rigidly attached thereto, a head for clamping and releasing the blade and a connection between said head and handle to permit of relative lateral swinging and shifting movement of the head in a line parallel to the axis of the handle for clamping and unclamping the blade between the head and guard member.
3. A safety razor including a flexible double edged blade and holding and clamping means therefor comprising a handle, a guard member rigidly attached thereto and a head having pivotal and slidable connection with the handle to permit of lateral swinging movement and movement in a line parallel to the axis of the handle for clamping and unclamping the blade to associate and disassociate the same therewith, the said means of connection consisting of a nut threadedly engaged with the handle, an element swiveled to the nut for axial movement therewith and arms rigidly connected to the head and pivotally connected with said element.
4. A safety razor comprising a handle, a reduced threaded shank at one end thereof defining a shoulder at its juncture, an arcuate guard member at the free end of the shank, an interiorly threaded nut mounted on the shank for longitudinal adjustments between the shoulder and the guard member upon rotation of the nut, a yoke including a bight element centrally swiveled to the nut and including side arms, each pivoted at one end to a free end of the bight, an arcuate head rigidly secured to the free ends of the side arm of the yoke, the said guard member having notches at its opposite ends receiving said side arms whereby to permit of a limited swinging movement of the yoke and head with respect to the guard member, and a flexible blade adapted to be clamped between the convex face of the head and the concaved face of the yoke upon adjustment of the nut between the shoulder.
