To all whom it may concern:
Be it known that I, Robert W. McGarvey, a citizen of the United States, and residing at Sparrows Point, Baltimore County, State of Maryland, have invented certain new and useful Improvements in Safety Razors, of which the following is a specification.
Numerous attempts have heretofore been made to provide a safety guard for razors which is as efficient in operation as the old-fashioned unguarded razor and which has at the same time the additional features of increased safety to the user, decreased bulk and cheapness. The general objects of this invention are to produce a razor which is simple, may be rapidly and easily stropped, and which allows a perfect control of the cutting edge of the razor in shaving.
The present invention provides a safety razor which has all the advantages of the unguarded razor and many advantages not realized by safety razors which have heretofore been constructed. It is simple, the blades may be easily stropped in the holder by even an inexperienced operator, and there is little danger of the strop being cut, the blades are quickly insertable and removable, a perfect control on the cutting edge is realized by the operator in shaving, and by the provision of two blades in the holder instead of a single blade the razor is rendered particularly useful to persons having tough beards who ordinarily must stop to replace a blade in the guard or holder before completing a shave, due to the fact that the first blade has become dull. The design of the frame or holder of this razor is such that in shaving it is gripped over a flat surface with the finger tips almost at the cutting edge of the blade, allowing a cutting stroke that cannot be equaled with safety by any other razor, especially razors having long handles giving a long leverage.
The blades can be not only conveniently stropped when in the holder but can be honed without removal therefrom simply by working them over a honing stone, and neither in stropping or honing is the skill required which is necessary in sharpening the old straight unguarded blade razor. One embodiment of the invention is disclosed by way of example in the following description when taken in connection with the accompanying drawings in which:
The frame of the razor comprises two similar plates
Each member is rotatable around one of the bars

What is claimed is:
1. In a safety razor, in combination, two razor blade supporting plates rigidly secured together at an angle, the space between the plates being unobstructed and each plate being of a size and shape to be conveniently grasped and held as a handle by the fingers, and a razor blade secured to each of said plates, the adjacent edges of said blades constituting cutting edges.
2. A safety razor having a frame comprising two plates arranged at an angle to each other and meeting in a common edge, two razor blades, and means associated with each plate for securing a razor blade thereto, said means being adjustable to hold the blade in a fixed position for shaving or in position for stropping.
3. A safety razor having a frame comprising two plates arranged at an angle to each other and meeting in a common edge, two razor blades, and means associated with each plate for securing a razor blade thereto, said means including a member having a pivotal connection with the plate and being adapted to hold the blade in fixed position for shaving or to allow the blade to swing for stropping purposes.
4. A safety razor having a frame comprising two plates arranged at an angle to each other rigidly secured together and meeting in a common edge which forms a guard, each plate having a recess adjacent and parallel to said edge, and means for securing a razor blade to either of said plates with its cutting edge parallel to the guard and overlying one of said recesses.
5. A safety razor comprising, in combination, a frame portion consisting of two plates arranged at an angle to each other and meeting in a common edge, said edge being toothed to form a safety guard, a bar secured to one of said plates near its outer edge, said bar being parallel to the toothed edge of the frame and slidable toward and away from the same, a razor blade pivotally secured to said slidable bar and means for locking said razor blade in operative position with its cutting edge adjacent and parallel to the toothed edge of the frame.
6. A safety razor comprising in combination, a plate, a blade carrying member pivotally and slidably secured to said plate, and means comprising interengaging portions of said plate and member for locking said member against movement, with the cutting edge of the razor blade parallel to and spaced from one edge of said plate, said latter edge acting as a safety guard, and a handle secured to said plate.
7. A safety razor comprising in combination, a plate, a bar slidably secured to said plate, a blade carrying member pivotally and slidably secured to said plate, and means comprising interengaging portions of said plate and member for locking said member against movement, with the cutting edge of the razor blade parallel to and spaced from one edge of said plate, said latter edge acting as a safety guard, and a handle secured to said plate.
8. In a safety razor, in combination, a flat plate, a blade carrying member pivotally secured to said plate and adapted to swing relatively thereto for stropping purposes, the swinging movement of said member in both directions being limited by abutment against the plate, to an angle of substantially 180°.
9. In a safety razor, in combination, a flat plate, a blade carrying member pivotally secured to said plate and adapted to swing relatively thereto for stropping purposes, the swinging movement of said member in both directions being limited by abutment against the plate to an angle of substantially 180°, and means for locking said member to the plate with the cutting edge of the blade in shaving position.
10. In a safety razor, in combination, a flat plate having a guard, a blade, a member carrying said blade and secured to said plate to swing about an axis parallel to the plate for stropping purposes and also slidable relatively to the plate into locking engagement therewith to be held thereby against such rotation, for shaving purposes, the swinging movement of said member in both directions being limited by abutment against the plate, to an angle of substantially 180°.
11. In a safety razor, in combination, a flat plate having a guard along one edge and two spaced parallel portions extending at right angles thereto, a bar having its ends slidably engaging said portions for movement toward and from the guard, and a blade pivotally supported on the bar and adapted to be swung about said bar as an axis for stropping purposes, or to be locked to said plate with its edge adjacent the guard, for shaving purposes.
12. In a safety razor, in combination, a flat plate having a guard along one edge and two spaced parallel portions extending at right angles thereto, a bar having slots in its ends to slidably receive said spaced portions of the plate and movable toward and from the guard, and a blade pivotally supported on the bar and adapted to be swung about said bar as an axis for stropping purposes, or to be locked to said plate with its edge adjacent the guard, for shaving purposes.
13. In a safety razor, in combination, a flat plate having a guard along one edge and two spaced parallel portions extending at right angles thereto, a bar having its ends slidably engaging said portions for movement bodily toward and from the guard, a member mounted on said bar and adapted to rotate about the bar as an axis or to engage the plate upon movement of the bar toward the guard to interlock therewith and to be held in fixed relation thereto, and a blade secured to said member.
14. In a safety razor, in combination, a flat plate having a guard along one edge and two spaced parallel portions extending at right angles thereto, a bar having its ends slidably engaging said portions for movement bodily toward and from the guard, a member mounted on said bar and adapted to rotate about the bar as an axis or to engage the plate upon movement of the bar toward the guard to interlock therewith and to be held in fixed relation thereto, and a blade secured to said member, the ends of said member and blade overlapping the parallel projecting portions of the plate so that rotation of the member and blade about the bar as an axis is limited to substantially 180°.
15. In a safety razor, in combination, two razor blade supporting plates rigidly secured together at an angle, each plate being of a size and shape to be conveniently grasped by the fingers and held as a handle, members attached to the plates adjacent their outer edges and forming projections normal to the plates, and a razor blade secured to each of said plates, the adjacent edges of said blades constituting cutting edges.
