2,012,868 Safety Razor with Continuous Blade Eivind Jensen Eckbo, Oslo, Norway. Application April 5, 1934. Serial No. 719,203.
In Norway April 11, 1933
2 Claims. (Cl. 30—12)

The present invention has for its object a safety razor of the kind which comprises a continuous blade in the form of a thin ribbon of steel, which is adapted to be wound from one spool to another across a guiding member serving as the usual guard for the sharpened edges of the blade during use.

The safety razor in accordance with the present invention comprises an oblong frame, which is provided at one end with a closed circular box for receiving a spirally wound new razor blade ribbon. The ribbon is adapted to be pulled out through a slot in the side wall of the box and from there passes over the guard or working member to a receiving reel provided with a suitable handle in order to be rotated for winding the used parts ribbon blade onto the same. The said reel may also be placed in a closed box similar to the one used for the new part of the ribbon, although this is not absolutely necessary.

The closed box or receptacle for the new continuous steel ribbon may be filled with vaseline or other lubricating material in order to prevent corrosion.

Intermediate the two spools for the new and used part of the steel ribbon the frame is provided with a working part or guard, which is adapted to be moved perpendicularly on the line connecting the two spool axes and which is adapted to be pressed against the lower side of the ribbon blade, being provided with the usual guard members on both sides.

On the top of the ribbon blade there extends between the two spools a longitudinal ribbon, which is securely connected with the frame and the part of which immediately above the adjustable guard is somewhat narrower than the blade, so that the edge of the blade projects a suitable distance on one or both sides of the same.

On the drawing a preferred form of the invention is illustrated.

Figure 1 is a side view, Figure 2 is a cross section on the line. II—II on Figure 1, Figure 3 is a secton on the line III—III on Figure 1 and Figure 4 shows a part of a preferred form of ribbon blade.

The safety razor comprises a frame 1, which may take the form of a disc, having an edge flange 2 giving the frame the form of a flat box, which may preferably be adapted to be covered by means of a disc 3, although this is not absolutely necessary.

Near one end of frame 1 there is located a disc-shaped receptacle 4, which may be provided with a particular cover or may be adapted to be closed by means of the previously mentioned covering disc 3 when the latter is put in position.

The receptacle 4 is provided in its side wall with a slot 5, through which the spirally wound ribbon blade 6 may be pulled out. The spirally wound spool 6 lies loose in receptacle 4 and the latter as previously mentioned may be filled with vaseline or other lubricating material in order to prevent corrosion.

Near the other end of frame 1 there is located a receiving reel 7, the shaft of which is provided with an exterior handle or knob 8. The front end of the razor blade ribbon is secured to reel 1 in some suitable manner and is wound onto said reel by turning handle 8, which may be associated with a suitable ratchet or the like.

Between the two spools blade 8 passes below a rib 9, which is secured to or integral with frame 1 or the edge flange 2 thereof. Below blade 8 there is located a clamping disc or guard member 10, which is secured to a rod 11 adapted to be longitudinally displaced in the guide 12 by means of screw 13 in order that the clamping disc 10 may clamp the razor blade against the ribbon 9 during the use of the razor. Clamping disc 10 has a straight middle part, but is somewhat curved near both ends, whereby the razor blade is caused to take a slightly curved shape, which May be an advantage in order to better reach the various parts of the face.

Along one or both sides the clamping disc is provided in the usual manner with guard teeth 14 or the like.

In the form illustrated on the drawing the blade is provided with edges on both sides, but the blade 2 may also be formed with edge on one side only, in which case the rib 9 may consist of a part of the flange 2 and be integral with or directly secured to disc 1 on the side at which the blade has no edge.

In order to protect the edge of the blade the same as illustrated on Fig. 4 may be provided with small projections 15 separating the parts 16 which are provided with razor edge on one or both sides.

What is claimed is:

1. A safety razor, comprising an oblong flat frame having a rib extending transversely across approximately the middle of one longitudinal side thereof, a spool in each longitudinal end of the frame, a continuous ribbon-shaped razor blade mounted on and extending between said spools, one spool containing the fresh blade portion and the other the used portion of the ribbon, and a clamping and guard member in said frame below the rib and between said spools, and adapted to be displaced transversely of the major axis of the frame, to clamp the blade into shaving position against said rib.

2. A safety razor, comprising an oblong flat frame having a rib extending transversely across approximately the middle of one longitudinal side thereof, a spool in each longitudinal end of the frame, a continuous ribbon-shaped razor blade mounted on and extending between said spools, one spool containing the fresh blade portion and the other the used portion of the ribbon, said razor blade being provided with laterally extending projections separating the sharpened edge parts of the blade, and a clamping and guard member in said frame between said spools, and adapted to be displaced transversely of the major axis of the frame, to clamp the blade into shaving position against said rib.
