To all whom it may concern:
Be it known that I, Frederick A. Clauberg, a citizen of the United States, and a resident of Weehawken Heights, in the county of Hudson and State of New Jersey, have invented a new and Improved Safety-Razor, of which the following is a full, clear, and exact description.
The purpose of the invention is to provide a very simple and effective type of safety-razor so constructed that two removable and interchangeable blades are employed which when placed in a body-frame back to back present two opposing cutting edges, the blades being primarily shaped for the purpose intended and made or sufficient thickness to admit of beveling their cutting edges, which bevel is so deep that the blades can be repeatedly honed, ground, and stropped with the best results.
Another purpose of the invention is to provide a frame constructed in detachable and adjustable sections and to provide simple, and conveniently-operated fastening devices for the frame, whereby as the blades are lessened in width by reason of repeated sharpening the sections of the frame can be adjusted to maintain proper relation to the blades.
It is also a purpose of the invention to provide removable clamps for the blades and fastening devices for the clamps readily accessible and conveniently operated.
A further purpose of the invention is to so construct the razor in its entirety that all of its parts may be separated, enabling them to be readily and quickly cleaned and rapidly and conveniently assembled and secured in assembled position.
The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
The razor consists, primarily, of two blades
In assembling the parts of the razor, supposing all of the parts to have been separated, the handle
One of the clamps
In order to enable the blades to be accurately and speedily set upon the wing-sections of the frame, lugs
The safety-razor constructed as above is very simple, its parts are all firmly held together when assembled and locked, and it is possible at any time to expeditiously and conveniently separate all the parts for cleaning or remove one or both blades for sharpening purposes, and as the blades become narrow through wear the guard members of the wing-sections may be adjusted properly relative to the edges of the blades.
Having thus described my invention, I claim as new and desire to secure by Letters Patent—
1. A safety-razor consisting of a body-frame constructed in two sections adjustable relative to each other, an intermediate connecting member for said sections, blades placed back to back and locked to the intermediate connecting member, being supported at their cutting edges by the two adjustable sections, means for locking the blades in position, and adjusting devices for the said frame-sections.
2. A safety-razor consisting of a central bar-section, slotted upwardly-curved wing-sections mounted upon the bar-section for movement to and from each other, blades placed back to back on the bar-section above said wing-sections, their cutting edges resting upon the wing-sections, and locking devices for the wing-sections and the said blades.
3. A safety-razor consisting of a central bar-section, slotted wing-sections adjustably mounted upon the bar-section, blades having retaining connection with the bar-section and supporting engagement with the wing-sections, locking-clamps for the ends of the blades, and a handle adapted for connection with the bar-section.
4. In safety-razors, a body-frame constructed in three sections, a bar-section and wing-sections, one at each side of the bar-section, the wing-sections comprising slotted horizontal body members and downwardly and upwardly curved guard members, set-screws passed through sundry of the slots in the body members of the wing-sections and into the bar-section, a handle passed through other of the slots of the body members of the wings and into the bar-section, blades having opposing beveled surfaces at their cutting edges, which blades are placed back to back in engagement with the bar-section, their cutting edges resting upon the guard members of the wings, and clamps removably carried by the said frame, engaging with the said knives or blades, preventing them from having end movement and holding them likewise against transverse movement.
5. A safety-razor consisting of a frame comprising a central bar-section and a wing-section at each side of the bar-section, each wing-section consisting of a horizontal body member having a series of slots therein, and downwardly and upwardly curved guard members, slotted at their outer longitudinal portions, forming a series of guard-fingers, the body members of which wings slide one upon the other beneath the bar member, and set-screws passed through the slots in the body members of the wings and into the bar member, a handle removably attached to the bar member, blades placed back to back against the bar-section of the frame, said blades having slots at their ends, their cutting edges resting upon the guard-fingers, and clamps removably attached to the ends of the bar-section of the frame, which clamps are provided with fingers extending into the slots of the blades and over the upper faces of the blades, the clamps being further provided with foot members which extend beneath and engage with the under faces of the body-frame at a point below the bar-section.
6. In safety-razors, a frame comprising guard-sections adjustable to and from one another, means for connecting the guard-sections, blades placed back to back and supported by the said guard-sections and their connecting medium, a handle for the frame, and locking devices for the blades and the guard-sections.
7. In safety-razors, a central bar-section, guards supported at opposite sides of the bar-section, adjustable to and from each other, independent blades having parallel relation to each other, which blades have bearing against the bar-section and are supported by said guards, locking devices for the blades, and means for adjusting the guards and locking them in adjusted position.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
Frederick A. Clauberg.
