To all whom it may concern:
Be it known that I, Arthur James Postans, a subject of the King of England, residing at Middlesex, in England, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.
This invention is for improvements in or releasing to safety razors of the circular blade type.
It has been proposed heretofore to employ an independent circular blade with a circular guard but a feature of the present invention consists in the blade being formed integral with or secured to part of the holder; this construction enables the blade to be easily handled.
In the accompanying drawings which illustrate one method of carrying out this invention—
Like letters indicate like parts throughout the drawings.
The circular blade
The guard comprises a disk
To bring the blade into position on the guard all that is necessary is to enter the stem
It will be seen that the razor consists of only two parts which are movable or separable and each of these is accessible from all points so that they can be easily cleaned. The stiff blade domed as shown enables moreover a good cutting edge to be provided and the parts being simple to construct enables the whole to be manufactured cheaply.
What I claim as my invention and desire to secure by Letters Patent is:—
1. A safety razor having a guard member and a blade member, the guard member having a handle rigidly connected thereto, there being a screw threaded orifice in said handle, the blade member having a threaded stem connected to its central portion, and arranged to engage the screw threaded orifice in the handle; substantially as described.
2. In a safety razor, the combination of a circular guard and a domed circular blade that overhangs that portion of the guard nearest the blade, of a central projection
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
Arthur James Postans.
