To all whom it may concern:
Be it known that I, Harold Edward Sherwin Holt, a subject of the King of Great Britain and Ireland, residing at The Grange, Farnborough, Hants, England, have invented certain new and useful Improvements in Razors, of which the following is a specification.
Hitherto in razors in which a very thin blade has been used it has been the practice to employ a rigid backing or support to impart the necessary rigidity to the blade, or to hold the thin blade by its ends on spring arms arranged to exert sufficient end tension on the blade to keep it rigid without any intermediate support or backing.
Now this invention has for its object to provide a simple form of blade holder or frame and handle for holding a thin blade by its ends and rendering the same rigid by end tension, or likewise holding a thick or rigid blade, but applying thereto either end tension or end pressure as desired.
Another object of this invention is to provide the handle and blade holder with a guard adapted to be easily and quickly moved away from the blade to allow the blade to be wiped, or with equal facility moved toward the blade and correctly positioned for shaving, the guard being held in parallel relation to the blade, both longitudinally and transversely, and moved parallel to itself and in a direction at right angles to the plane of the blade during the adjustment to insure perfect safety.
According to one practical form of this invention the ends of the blade are held on the branches or arms of a fork shaped holder, and one of such arms is capable of being adjusted relatively to the other arm to apply tension to the blade or pressure as the case may be, by suitably operating a handle adjustably connected with the back of the fork. The guard is mounted between the blade and the back of the fork, being guided by the arms of the fork and adjusted by a stem which passes through the handle and is fitted with a positioning stop. In a slightly modified form of construction the guard is guided by the arms of the fork during a small portion only of its movement or preferably just sufficient to allow it to be adjusted in relation to the cutting edge and when drawn back beyond this limit is automatically released from the guides enabling it to move or be moved outward away from the blade.

Another method of holding the blade
What I claim and desire to secure by Letters Patent is:—
1. A safety razor comprising a blade having openings near its ends, a blade holder having substantially parallel arms projecting from the ends thereof and engaging the openings in the blade, one of said arms being pivoted to the blade holder and having an inwardly extending portion, said blade holder having a central threaded opening, a handle having a portion screwing into said threaded opening and having an annular shoulder bearing against the end of said inwardly extending portion of the movable arm, a guard guided by said parallel arms, and means for moving the guard toward and from the blade.
2. A safety razor comprising a blade having openings near its ends, a blade holder having substantially parallel arms projecting from the ends thereof and engaging the openings in the blade, one of said arms being pivoted to the blade holder and having an inwardly extending portion, said blade holder having a central threaded opening, a handle having a portion screwing into said threaded opening and having an annular shoulder bearing against the end of said inwardly extending portion of the movable arm, a guard guided by said parallel arms, said handle having an axial passage therethrough, a rod connected to the guard and extending through said passage, means at the outer end of the handle for moving the rod longitudinally of the handle, and means carried by the handle for locking the rod in place.
3. A safety razor comprising a blade holder having substantially parallel arms at the ends thereof, a blade having openings engaged by said arms, a tubular handle connected to said blade holder, a guard slidable on said arms toward and from the blade, a stem secured to the guard and extending through the tubular handle, and means for locking the stem against longitudinal movement within the handle.
In testimony whereof I have affixed my signature, in presence of two witnesses.
