To all whom it may concern:
Be it known that I, Jacob Schick, a citizen of the United States, and a resident of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Safety Razors, of which the following is a specification.
This invention relates to an improved safety razor which is adapted to use what are commonly known as wafer blades, that is, thin blades, these blades being held within the razor and adapted to be fed therefrom into shaving position when desired, and can be pushed beyond the shaving position for ejection or either to be replaced by a new blade or for the purpose of washing the blade and the razor.
The invention is designed to provide a razor or this kind in which the movement of the magazine can be extended to a point where the magazine is uncovered, whereby a new series of blades can be inserted in the magazine.
The invention further consists in certain details of construction which will be hereinafter more fully described and finally embodied in the claims.
One form of razor embodying my invention is illustrated in the accompanying drawing, in which
In the form shown the handle
The front lip
I provide a yielding means for holding a series of wafer blades that are in the magazine so that they are in position to be successively removed into shaving position. The blades
One means of swinging the plate is shown in the drawing, this means including a curved rack
In order to insure a tight joint between the upper face of the magazine and the lower face of the positioning plate, even under excessive wear, I provide a yielding means, the form shown comprising a spring
Different positions of the razor parts can be indicated by suitable indicating marks or insignia, shown at
To hold the blades in alignment I provide suitable aligning means, in the form shown this comprising convex portions
The operation of the razor is as follows: Assuming that the razor is empty and in the position shown in
If a blade is needed, the part
After the shaving is completed, or if it is necessary to remove the blade, the blade which is in position for shaving can be ejected by swinging the magazine backward until the shoulder
It will thus be seen that the razor, when properly operated, will successively remove the blades from the stack of blades in the magazine, that the device can be operated to eject a blade and be in position to have it replaced therein, so that a blade can be used again in the razor without disturbing the stack of blades in the magazine.
The device is illustrated with the magazine swinging under the positioning plate, but it will be evident that other means and other arrangements of parts can be devised for bringing about the result desired, my invention residing in a razor adapted to successively use blades from a stack of blades, and the invention is designed to include such equivalent motions and mechanisms as will bring about such functioning.
I claim:
1. A safety razor comprising a guard, positioning means for holding a blade in shaving position on the guard, a magazine for separate wafer blades, and positive means for feeding blades in succession from the magazine to the positioning means.
2. A safety razor comprising means for holding a blade in shaving position, a magazine for separate wafer blades, and positive means for successively feeding blades from the magazine to shaving position in the holding means.
3. A safety razor comprising means for holding a blade in shaving position, a magazine for wafer blades, and means for successively feeding blades from the magazine to shaving position in the holding means, said feeding means being disposed so that excess movement thereof ejects a blade in shaving position from the razor.
4. A safety razor comprising a handle with a positioning plate at the top, a guard, a magazine for wafer blades on the guard, the guard and positioning plate having a connection so that one is movable relative to the other, whereby such movement will successively feed blades in the magazine into shaving position between the positioning plate and the guard.
5. A safety razor comprising a handle with a positioning plate on the top thereof, a magazine swinging under the positioning plate, a guard on the magazine, means for swinging the magazine, the magazine and positioning plate having coacting means to feed wafer blades from the magazine to shaving position between the positioning plate and guard when the magazine is swung.
6. A safety razor comprising a handle with a positioning plate on the top thereof, a magazine swinging under the positioning plate, a guard on the magazine, means for the magazine, the magazine and positioning plate having coacting means to feed wafer blades from the magazine to shaving position between the positioning plate guard when the magazine is swung, said coacting means, when moved beyond the shaving position of the blade, acting to eject a blade in such position from the razor.
7. A safety razor comprising a handle including a post and a positioning plate spaced above said post, a magazine swinging in the post and with its top edge abutting on the positioning plate, a guard on the magazine, the magazine being adapted to hold a series of wafer blades, a spring acting to eject said blades from the magazine, the bottom face of the positioning plate being formed to engage and remove the top of said blades when the magazine is swung.
8. A safety razor comprising a handle including a post and a positioning plate spaced above said post, a magazine swinging in the post and with its top edge abutting on the positioning plate, a guard on the magazine, the magazine being adapted to hold a series of wafer blades, a spring acting to eject said blades from the magazine, the bottom face of the positioning plate being formed to engage and remove the top of said blades when the magazine is swung, the handle including rotative means for imparting a swinging motion to the magazine, said rotative means being provided with a chamber for receiving a package of blades.
9. A safety razor comprising a handle with a divided post and a positioning plate, a magazine swinging in said post and against the positioning plate, yielding means for holding the magazine in contact with the positioning plate, a guard on the magazine, the magazine being adapted to hold a series of razor blades, yielding means for forcing said series of blades against the positioning plate, the positioning plate having a shoulder to remove the top blade from the series of blades when the magazine is swung, and adapted to eject said blade from the razor when the magazine is subjected to excess movement beyond the shaving position.
10. A safety razor comprising means for holding a blade in shaving position, a magazine for wafer blades, said holding means and the magazine being movable relative to each other, and coacting means actuated by the relative movement. of said parts to positively feed a blade from the magazine to shaving position in the holding means.
11. A safety razor comprising means for holding a blade in shaving position, a magazine for holding a stack of blades, and means for feeding a blade from said stack to shaving position in the holding means.
12. A safety razor comprising means for holding a blade in shaving position, a magazine for holding a stack of blades, said holding means and the magazine being movable relative to each other, and coacting means on said parts actuated by the relative movement of said parts for feeding the top blade from the stack to shaving position in the holding means.
In testimony that I claim the foregoing, I have hereto set my hand, this 20th day of June, 1921.
JACOB SCHICK.
