To all whom it may concern:
Be it known that I, Cap Bertrand Collins, a citizen of the United States, residing at Des Moines, county of Polk, and State of Iowa, have invented certain new and useful Improvements in Rotary Safety-Razors, of which the following is a specification.
This invention relates to improvements in rotary safety razors, and one of the objects of the same is to provide an improved self-contained motor propelled device of this character having a rotary circular blade.
A further object is to provide an improved device of this character having a blade of disk shape provided with a continuous non-serrated cutting edge, and a guard for the blade.
A further object is to provide improved means for controlling the operation of the blade.
To the attainment of these ends, and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating the invention, and in which—
Referring more particularly to the drawings and in the present exemplification of this invention, the numeral
The housing is preferably constructed in sections and connected with one section by means of a reduced portion
The cutting blade
Arranged within the casing
In use, the spring
In order to control the rotation of the blade, a stop device is provided which cooperates with the toothed element
With this improved construction it will be manifest that a simple, durable, compact and efficient device is provided, one in which all of the parts are concealed and protected, and one which may be readily manipulated, while at the same time, the blade
Obviously many changes may be made in the details of construction and in the combination and arrangement of the several parts without departing from the spirit of this invention.
What is claimed as new is:—
1. A self-contained device of the character described, embodying a substantially flat circular motor casing, said casing constituting a housing, a stem projecting from and arranged perpendicularly to one of the walls of the casing, a guard connected with the stem and disposed adjacent the casing, a driving shaft extending from the casing and through the said stem, a blade detachably connected with the shaft and disposed adjacent the guard, a stop device adjustably supported by the guard, said stem provided with a lateral opening therethrough adjacent the guard, a portion of said stop device projecting through said opening, and means on the shaft with which the said portion of the stop device coöperates.
2. A self contained razor of the character described, embodying a motor propelled rotatable disk shaped blade, a guard for the cutting edge of the blade, said guard having a chamber therein, an element disposed within the chamber, and rotatable with the blade, and means coöperating with the said element for controlling the operation of the motor.
3. A self contained razor of the character described, embodying a motor propelled rotatable disk shaped blade, a guard for the cutting edge of the blade, said guard having a chamber therein, a rotatable toothed element disposed within the chamber and connected with the motor, and an element shiftable into and out of engagement with the toothed element for controlling the motor.
4. A self contained razor of the character described, embodying a motor propelled rotatable disk shaped blade, a guard for the cutting edge of the blade, said guard having a chamber therein, a rotatable element disposed within the chamber, and connected with the motor, and an element supported by the said guard, and movable into and out of operative relation with the said element for controlling the operation of the motor.
In witness whereof, I hereunto subscribe my name to this specification in the presence of two witnesses.
Cap Bertrand Collins.
