To all whom it may concern:
Be it known that I, Alexander G. Johnson, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Razors and the Like, of which the following is a specification.
This invention relates to razors and similar instruments, and aims to provide certain improvements especially applicable to razors.
In the usual construction of razor as heretofore employed the blade has been pivoted at right angles to its length to swing open and closed from and toward a handle open at both front and back, and the user has retained the blade in any desired open position by a lock or by grasping the tang with the thumb and first finger and holding the handle with the other fingers.
In using a razor the handle sometimes interferes with the desired movement of the blade and much awkwardness and difficulty are encountered in shaving certain portions of the face. To avoid such interferences as far as possible, it has been common for users of razors to tilt the handle on its pivotal connection with the blade to various angles relatively to the latter. To correct this, it has been attempted to provide a razor in which the blade can be moved to various positions at right angles to the direction in which the blade moves in opening or closing the razor and in which the blade may be held in one of several positions without the aid of the fingers.
My invention aims to provide certain improvements especially applicable to such razors.
To this end, in carrying out the preferred form of my present improvements as applied to a razor having a swivel connection between the blade and handle extending on an axis preferably parallel with the plane through which the blade moves in opening and closing the razor, so that the blade can be swung on this axis to occupy any desired position or positions laterally of the handle, I provide improved means for locking this swivel, so that the blade may be used as the ordinary razor-blade, and I provide a wide handle having a closed back and the usual knife-spring and a tang having steps or faces reciprocal to this spring and adapted to hold the blade in any one of several open positions or in the closed position, so that the razor may be used with certainty that it will retain its adjustment and may be closed and carried with safety.
In the accompanying drawings, which show one adaptation of my present improvements,
Referring to the drawings, I will now describe in detail the preferred form of my present invention.
Let
According to the construction of razor shown the blade and handle are so connected in any suitable manner that the handle can be swung sidewise or turned relatively to the ‘blade in other than the direction of its usual opening and closing movements. This may be variously accomplished; but I prefer to attain it by subdividing the tang into two ends
My invention provides means for locking the blade in position relatively to the handle, for which purpose I prefer the construction of lock shown at
Another feature of improvement consists in forming the tang with locking-faces
In use the razor may be honed and used as an ordinary razor by locking the swivel connection
By side swinging the user can avoid interference of the blade in shaving, and by setting the razor at different open positions
When not in use, the razor can be safely carried in the pocket without danger of opening of the blade.
The razor can be honed, stropped, and cleaned as conveniently as can ordinary razors.
It will be seen that my invention provides improvements which can be readily and advantageously used, and it will be understood that I do not limit myself to any particular details of construction, arrangement, and combination of parts and features shown as constituting the preferred form of the invention, since my improvements can be employed in whole or in part, according to such modifications as circumstances or the judgment of those skilled in the art may dictate, without departing from the spirit of my invention.
What I claim is—
1. In razors and the like, the combination with a handle, of a blade carried thereby, a swivel connection between the parts permitting swinging of the blade sidewise relatively to the handle, and a hinged lock swinging toward the blade to lock it relatively to the handle.
2. In razors and the like, the combination with a blade, of a separate tang therefor, said blade hinged to said tang and swinging relatively thereto, and a lock hinged to one of said parts and swinging thereon toward and from the other for locking them together.
3. In razors and the like, the combination with a blade, of a separate tang therefor, said blade pivoted to said tang and swinging transversely thereof, and a swinging lock for fastening said parts rigidly together.
4. In razors and the like, the combination with a handle
5. In a razor, the combination with a handle and a spring, of a blade having a tang, having a plurality of spring-faces, and a pivotal connection between said tang and handle, whereby the blade can be held in successive positions by the spring, a pivotal connection between the blade and tang permitting swinging of the blade transversely of the tang, and a swing-lock hinged to one of said parts and locking the blade in position.
In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
Alexander G. Johnson.
