My invention relates to safety razors and has for its principal objects a razor in which the angular position of the blade may be easily adjusted, in which the blade is easily removable from and insertable in the blade holder, and which is simple in construction.

The invention consists in the safety razor and in the parts and combinations of parts hereinafter described and claimed.

In the accompanying drawing which forms part of this specification.

Fig. 1 is a front elevation of a safety razor embodying my invention,

Fig. 2 is a side elevation, the dash lines showing the blade holding clamp depressed so as to permit removal of a blade,

Fig. 3 is a side elevation similar to Fig. 2, showing the blade in a different position from that shown in Fig. 2, and

Fig. 4 is a rear elevation.

A blade holder A is pivotally secured to the end of a suitable handle 1. The blade holder comprises an inclined face 2 constituting a rest or support for a razor blade 3, a face 4 that has an offset portion 5 frictionally engaging said handle 1 and a curved connecting portion 6. The faces 2 and 4 form a dihedron, being formed with respect to one another as a dihedral angle is formed. Preferably a tongue 7 is struck up from the blade supporting face 2 and disposed parallel to the body portion of the clamping face 4 of the blade holder. A pivot pin 8 extends through said tongue 7, said handle 1, and said clamping face 4 of the blade holder, whereby the blade holder is capable of rotary movement. Preferably the clamping face 4 of the blade holder has a curved edge 9 and the offset portion 5 is a segmental area at the middle portion of said face. The handle 1 is preferably flattened on the sides 10 adjacent to said tongue 7 and said clamping face 4 of the blade holder.

Near each side, adjacent to the curved connecting portion 6, the clamping face 4 of the blade holder is provided with a projection 11. When the blade holder is rotated to the limit of its movement in either direction so that the handle 1 extends along the trough formed by the curved connecting portion 6 of the blade holder, the handle is frictionally engaged by one of said projections 11 and the blade holder is held in position.

In order to hold the blade 3 in position on the blade rest 2, a clamp 12 of more or less U-shape is provided. Said clamp 12 is of spring metal and has a portion 13 that engages the blade 3 near the cutting edge thereof to hold it in position. Said clamp 12 is provided with securing tongues 14 that are disposed in slots 15 provided therefor in the blade supporting portion 2 of the blade holder and constitute abutments for the rear edge of the blade. To the rear of the blade 3, the clamp 12 is spaced away from the blade holder, except at its rear edge portion 16 where it engages the clamping face 4 of the blade holder and assists in keeping said clamping face in frictional engagement with the handle.

To the rear of the blade 3, the blade supporting face 2 of the blade holder is provided with spaced projections 17. If the clamp is depressed to the rear of these projections 17, the front portion of the clamp is swung upwardly, thus releasing the blade and permitting it to be withdrawn from the blade holder.

The above described razor has numerous advantages. The angular position of the blade holder may be adjusted so that the blade is in the same position as the blade of the ordinary safety razor, it may be adjusted to give the blade an angular position so as to permit a diagonal stroke in using the razor, or it may be adjusted so that the blade extends along the handle in a position similar to that of the blade of a straight razor. All of these adjustments are easily made without the necessity for loosening and then tightening securing devices. A blade may be easily and quickly removed from the holder and a new blade inserted.

Obviously, numerous changes may be made without departing from the invention and I do not wish to be limited to the precise construction shown.

What I claim is:—

1. A safety razor comprising a handle, a blade holder, said blade holder comprising a blade rest, a clamping face having a portion engaging said handle and a tongue struck up from said blade rest and bent against said handle, and a pivot pin passing through said clamping face, said handle and said tongue.

2. A safety razor comprising a handle, a blade holder, said blade holder comprising a blade rest, a clamping face having a portion engaging said handle and a tongue struck up from said blade rest and bent against said handle, a pivot pin passing through said clamping face, said handle and said tongue, and a clamp engaging said blade and said clamping face of said holder.

3. A safety razor comprising a handle, a blade holder of angular section pivotally secured thereto, a clamp of substantially U-section, one end portion of said clamp engaging a blade on said holder and the other end of said clamp engaging said holder, said clamp having tongues disposed in slots provided therefor in said holder.

4. A safety razor comprising a handle, a blade holder of angular section pivotally secured thereto, a clamp of substantially U-section, one end portion of said clamp engaging a blade on said holder and the other end of said clamp engaging said holder, said clamp having tongues disposed in slots provided therefor in said holder, and said holder being provided with projections to the rear of said blade adapted to engage the clamp when the rear portion is depressed, and cause the front portion of said clamp to be raised to release the blade.

5. A safety razor comprising a handle, a blade holder pivotally secured thereto, said blade holder having a clamping face, said clamping face having a curved edge portion and provided with an offset portion frictionally engaging said handle, a blade on said holder and a resilient clamp engaging said blade and said clamping face of said blade holder, whereby a single reaction of the clamp presses the offset portion against said handle and holds the blade.

6. A safety razor comprising a handle, a blade holder pivotally secured thereto, said blade holder having a clamping face, said clamping face having a curved edge portion and provided with an offset portion frictionally engaging said handle, a blade on said holder and a clamp engaging said blade and said clamping face of said blade holder, said clamp being secured to said holder by tongue and slot connections.

7. A safety razor comprising a handle, a blade support pivotally secured thereto, said blade support having a clamping face provided with an offset portion frictionally engaging said handle for resiliency holding the support at various positions, a blade and a clamp for holding said blade on said support, and lugs at the sides of said clamping face adapted to engage said handle when the offset portion of said holder has been swung clear of said handle, the juncture between the face and the blade support being adapted to positively limit the consequent swing of the blade support by cooperation with a portion of said handle.

8. A safety razor comprising a blade rest and a clamping face formed together as a dihedron, a handle pivoted inwardly of the dihedron, means on the said clamping face for resiliently engaging the handle for variably positioning the dihedron over a predetermined range of positions, and means within the dihedron for engaging the handle in a fixed position when the handle is substantially parallel to the juncture of the dihedral faces and beyond said predetermined range of movement.
