4 Claims.

The invention relates generally to razors andv a blade having a series of openings so arranged that when the blade is clamped in a holder accommodating such openings, the blade is curved about an axis diagonal to its cutting edges.

Another object of the invention is to provide a blade of the last mentioned character, which is also adaptable for use in the ordinary or standard type of safety razor.

Other objects of the invention will become apparent from the following specication, from the drawing to which it relates and from the claims hereinafter set forth.

For a better understanding of the invention reference may be had to the accompanying drawing wherein:

Figure 1 is an elevational View of a razor constructed according to one form of the invention;

Fig. 2 is a plan view of the razor shown by Fig. 1;

Fig. 3 is a cross-sectional view taken substantially along the line 3-3 of Fig. 2;

Fig. 4 is a cross-sectional view taken substantially along the line 4-4 of Fig. 2;

Fig. 5 is a detailed view illustrating a blade embodied in the razor;

Fig. 6 is a cross-sectional view of the blade shown in Fig. 5; and,

Fig. 7 is a detailed view of a blade constructed according to another form of the invention.

Referring to the several gures the handle of the razor is indicated at I and may be of standard form so as to include a threaded opening II at its upper end. The holder for the razor blade includes a lower element I2 having a guard I3 at each edge, and an upper cap I4. The cap I4, as best shown by Figures 3 and 4, has studs I6 and Il at opposite ends and which are adapted to project through openings in the razor blade, while at the center of the cap a threaded stud I8 is provided which is adapted to be threaded into the opening II in the handle. A razor blade clamped between the cap and element I2 is shown at 20 and generally is of rectangular shape with opposite longitudinal edges parallel and constituting cutting edges.

As best shown by Figure the blade has a central opening 22, a pair .of v.end openings 23 and 2li adjacent oneend of .the .blade and a second pair 'of end openings 25 and l26 adjacent the oppositeend of `the iblade. The centers lof openings '24, 22, and 125 are ylocatedon a line inclined to the cutting edges and generally diagonal thereto, while the centers of openings 23, 22, and 26 are located on a diagonal line running crosswise of the lrst diagonal line. The openings are so arranged that each pair of end openings is symmetrical to the center line parallel to the cutting edges and passing through the center of the common opening 22 and it follows from this that the blade may be used in either one position or a reversed position.

The studs I6, Il and I8 on the cap I4 have their centers arranged on a like diagonal line and the cap is curved about this line. Similarly, the guard element I2 has openings adapted to receive the three studs and such element is curved in accordance with the cap I4. It should now be apparent if the blade is placed between the cap and guard element with the studs projecting through one line of diagonal openings and through corresponding openings in the guard element, that the blade may be brought into a curved condition as shown in Figures 1J 3, and 4, when the handle is threaded onto the stud I8. During this clamping of the blade in position, it is automatically curved about one diagonal axis. If the blade is reversed in position, its opposite set of diagonal openings will be engaged by the studs and curving of the blade will occur about this alternative axis. When the blade is used, it is manipulated in the usual manner, but due to the diagonal position of the cutting edges, the beard is met by the cutting edge at an angle so that shearing of the hair occurs with a slicing action in contrast to direct pushing action.

The blade shown by Figure 7 is adapted to be used in the same manner as the blade shown at Figure 5. In this case, instead of having ve separate openings in the blade, openings 30, 3l, 'and 33 at opposite ends and an opening 34 formed at the center are interconnected by a slot 35 running parallel to the cutting edges and intersecting the opening 34. This slot extends to a line joining the end openings and an opening 35 at one end and an opening 31 at the other effect communication between the slot and the end openings. This type of aperture arrange ment in the blade permits its use in a standard type of safety razor, while at the same time it includes the two sets of diagonally aligned openings permitting its use in the razor previously described. Thus, the blade may be selectively used in either the standard type of razor or the type particularly shown in the drawing.

Although more than one form of the invention has been illustrated and described in detail, it will be apparent to those skilled in the art that various modifications may be made without departing from the scope of thek appended claims.

What is claimed is:

1. In a safety razor, a flexible sheet metal blade having the shape of a rectangle, a holder for the blade, and means for securing the blade to the holder so as to flex the blade about an axis extending diagonally of the rectangle.

2. In a safety razor, a flexible sheet metal blade provided with opposed parallel cutting edges and three apertures in alignment diagonally of the blade in one direction and three apertures in alignment diagonally of the blade in the opposite direction, the central aperture being common to both sets of diagonally aligned apertures, and a holder arranged to ex the blade about one set of diagonally aligned apertures, the blade being so constructed that it may be reversed in the holder and exed about the other set of diagonally aligned apertures.

3. In a safety razor, a flexible sheet metal blade provided with opposed parallel cutting edges and three apertures in alignment diagonally of the blade in one direction and three apertures in alignment diagonally of the blade in the opposite direction, the central aperture being common to both sets of diagonally aligned apertures, and a holder arranged to ex the blade about one set of diagonally aligned apertures, the blade being so constructed that it may be reversed in the holder and flexed about the other set of diagonally aligned apertures, said blade also having a central slot extending parallel to the cutting edges and intersecting said common aperture.

4. In a safety razor, a flexible sheet metal blade provided with opposed parallel cutting edges, a central slot extending parallel to said edges, and a pair of openings at each end of the slot and disposed respectively at opposite sides of such slot, and a holder arranged to flex the blade about a diagonal line extending through either pair of diagonally arranged openings and through the center point of the slot.
