To all whom it may concern:
Be it known that I, George Arthur Schieren, a citizen of the United States, residing at Beachleigh, Great Neck, in the county of Nassau and State of New York, have invented certain new and useful Improvements in Safety Razors, of which the following is a specification.
The present invention relates particularly to an index adjusting device for use in connection with safety razors of the Gillette type wherein a flexible and elastic blade is provided with cutting edges that are adjustable toward or from the guard member of the razor. This adjustment of the cutting edges of the blade is accomplished by turning the handle of the razor to the desired position with relation to the head of the razor. In actual practice, after the user has shaved, assuming the blade to be in correct position during the operation, when the razor is taken apart for cleansing, the former correct position or adjustment of the blade is lost. When the razor is again to be used, the former correct position of the blade can only be secured by trial and frequent changes in the adjustment of the blade.
The primary object of my invention is the provision of means, in combination with the razor, by which the blade may successively be adjusted to exactly the same angle every time it is used, thus insuring at all times a known and correct adjustment of the blade, and eliminating loss of time and annoyance otherwise attendant upon the adjustment of the blade by trial.
To this end the invention consists essentially in the combination with the handle and head of the razor of this type, of an index member adjustable on the handle and complementary to a stationary index member preferably on a portion of the head of the razor, by means of which a uniform adjustment of the blade may be secured with facility and convenience.
In the accompanying drawing I have illustrated one complete example of the physical embodiment of my invention, wherein the parts are combined and arranged according to the best mode I have thus far devised for the practical application of the principles of my invention. It will be understood however that changes and alterations may be made in the device as shown without departing from the spirit of my invention, and within the scope of my appended claim.
In the preferred form of the invention as illustrated in the drawings a safety razor of the Gillette type is shown having the rotatable handle
The flexible, elastic blade is clamped between the guard plate
After this proper position or adjustment of the cutting edges of the blade has been secured, I utilize my index device in order that said adjustment may again readily be secured, after the razor has been dismantled for cleansing and is again put together for use. In carrying out my invention I utilize a stationary finger or pointer
Between the body of the handle and its socket-head
Because of this frictional connection, the sleeve may be rotated or revolved about the neck portion of the handle by pressure applied through the thumb and fingers. Thus, assuming that the handle has been turned and the edges of the blade have been properly positioned with respect to the guard plate
In adjusting the index sleeve, the handle is first turned until a slight or initial frictional contact is made between the head
In the modification of the invention as shown in
The index is impressed or stamped on the sleeve
From the above description taken in connection with my drawings, it will be apparent that I have provided an index device that is compactly arranged, comparatively inexpensive in cost of manufacture, and simple, but efficient in performing its required functions.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:
In a razor the combination of a clamp plate having a threaded stem, a blade, a guard, a threaded handle having a socket-head, said head being in contact with the guard, an index sleeve on the handle and below said head, resilient means between the sleeve and handle, and a single index in connection with the guard, whereby a predetermined width and angle of the cutting blade is reset by a single adjustment.
