To all whom it may concern:
Be it known that I, Alexander G. Johnson, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Razors, 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 razors 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.
To avoid the awkwardness and difficulty encountered when the blade is extended in line with the handle, it has been customary for the user to tilt the blade at various angles to the handle in order to facilitate shaving certain portions of the face. This often results in a strained or awkward position of the hand, so that shaving is rendered more difficult and danger of cutting the face is incurred. To avoid this difficulty, it has been proposed to pivot the blade relatively to the handle, so that while adapted to swing toward and from it in the usual way it is also capable of a transverse movement, one such construction being shown in my Patent No. 637,124, dated November 14, 1899.
My present invention aims to provide an improved construction of razor whereby the blade is capable of being rotated or turned relatively to the handle, so that while the latter may be held by the hand in the most natural position for ease of manipulation the blade may be turned relatively thereto to the most suitable angle, so that any part of the face may be shaved without twisting the wrist or hand. I preferably combine with this feature of my invention the capability for sidewise movement before referred to, so that while the blade may be twisted to any desired angle relatively to the handle it is also capable of being swung transversely thereto.
In its preferred form my invention provides a razor in which the blade is adapted to swing open to an extent only sufficient to bring it in line with the handle, where it is held by a suitable stop against further movement. When this is done, my invention provides a means whereby the blade may be turned completely around, so that its position relatively to the handle is reversed, whereupon the blade may be tilted in the usual manner, if desired, about the pivot by which it is connected to its handle, thus permitting its use in the same manner as the common form of razor, and I also preferably provide means for locking the blade in this position, so that in stropping the blade is held firmly by its stop and cannot be accidentally closed by the force of its contact with the strop.
My invention also provides certain other improvements, all of which will be more clearly set forth.
In the accompanying drawings, illustrating my invention,
Referring to the drawings, I will now describe in detail the preferred form of my present invention.
Let
According to one feature of my invention the blade
Another feature of improvement consists in forming a single connection which permits the rotation of the blade relatively to the handle and also provides for its adjustment transversely thereto. For this purpose I so proportion the neck
According to another feature of improvement I provide means whereby the blade may be locked rigidly with the tang
By another feature of improvement I provide means whereby the blade may be rotated to a position at right angles to the handle, as seen in
With razors of common construction it is customary to provide the tang with a portion which extends inwardly of the blade beyond its pivotal connection with the handle, this portion being held within the handle when stropping to insure that the blade and handle are approximately in alinement and that the blade will not close upon the hand. By my invention this part is rendered unnecessary, and the length of the razor when closed may thus be reduced. For this purpose, by another feature of improvement, I provide means whereby the blade may be held rigidly during stropping or at other times when desired, so that it is impossible for the edge of the blade to close upon the hand of the user. In the preferred form of my invention I preferably utilize the lock
While providing for the rotative movement of the blade and its transverse movement relatively to the handle, I prefer that the blade shall not be capable of movement relatively to the tang
It will be seen that my invention provides improvements which can be readily and advantageously availed of, and it will be understood that I do not limit myself to the 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 and a blade pivoted to and closing against said handle, of a connection between said blade and handle permitting relative rotative movement thereof around the longitudinal axis of one of said parts.
2. In razors and the like, the combination with a handle, a tang pivoted to said handle, and a blade carried by said tang and closing against said handle, of a connection between said tang and blade permitting relative rotative movement of said tang and blade around the longitudinal axis of the latter.
3. In razors and the like, the combination with a handle, and a blade pivoted to and closing against said handle, of a swivel connection between said handle and blade, permitting said blade to oscillate on its longitudinal axis relatively to said handle.
4. In razors and the like, the combination with a handle, a tang pivoted to said handle, and a blade carried by said tang, of a swivel connection between said tang and blade for permitting rotation of said blade relatively to said tang.
5. In razors and the like, the combination with a handle, of a blade carried thereby, said handle having a socket, and said blade having a protuberance held within said socket by frictional engagement therewith, said socket and protuberance constituting a swivel connection between the blade and handle permitting the blade to oscillate around its longitudinal axis and transversely thereof.
6. In razors and the like, the combination with a handle and a blade carried thereby, of means permitting rotative movement of said blade about its longitudinal axis, and means permitting transverse swinging of the blade relatively to the handle.
7. In razors and the like, the combination with a handle and a blade pivoted thereto and closing against said handle, of means for reversing the position of the blade relatively to the handle, so that pressure upon the back of the blade does not tend to close it.
8. In razors and the like, the combination with a handle and a blade pivoted thereto and closing against said handle, of means for reversing the position of the blade relatively to the handle, so that pressure upon the back of the blade does not tend to close it, and a lock locking said blade in its reversed position.
9. In razors and the like, the combination with a handle and a blade closing against said handle, of a connection between said blade and handle permitting reversal of the blade relatively to the handle, so that pressure upon the back of the blade does not tend to close it.
10. In razors and the like, the combination with a handle and a blade closing against said handle, of a connection between said blade and handle permitting reversal of the blade relatively to the handle, so that pressure upon the back of the blade does not tend to close it, and a lock for locking said blade in said reversed position.
11. In razors and the like, the combination with a handle, and a blade carried thereby, of a swivel connection between said handle and blade for permitting rotative movement of said blade relatively to the handle, and means for fixing said blade in a plurality of different positions.
