2 Claims.

This invention relates to new and useful improvements in knives, the principal object being to provide means whereby razor blades can be converted for use as pen knives, pocket knives and the like.

Another important object of the invention is to provide holder or shield means for razor blades whereby the blades can be readily used for purposes other than shaving.

Other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawings:

Figure 1 represents a front elevational view of one form of the invention.

Figure 2 is a side elevational view with the shield partly slid from the blade.

Figure 3 is an end elevational View of the structure shown in Figure 1.

Figure 4 is a perspective view of the structure shown in Figure 1 with the shield partly slid from the blade.

Figure 5 is a side elevational view of a modified form.

Figure 6 is a side elevational view of the structure shown in Figure 5 with .the shield partly removed.

Figure 7 is an end elevational view of the structure shown in Figure 5.

Figure 8 is a perspective view of the parts of the form of the invention shown in Figure 5 partly taken apart.

Figure 9 is a side elevational view of the third form of the invention.

Figure 10 is a side elevational view of the third form of the invention with the parts in shifted position.

Figure 11 is an end elevational view of the structure shown in Figure 9.

Referring to the drawings wherein like numerals designate like parts, it can be seen that Figures 1 to 4, inclusive, represent one form of the invention. This form of the invention consists of a shield generally referred to by numeral 5 for disposition on a blade 6 of a conventional design. The blade 6 is of the type having a single edge 1, a reinforced back 8 and

notches

9, 9 at the end portions thereof.

The shield 5 consists of a plate of spring metal manufactured in a barrel form H! at its intermediate portion and to provide contacting win-g portions I I, I l for snug engagement against opposite sides of the blade 6. One end of each of the,

wings I has an opening I2 therein, these openings being registered with respect to each other to accommodate a link or watch chain. Obviously. the, shield can be pulled to the position shown in Figure 4 so that the blade can be used for cutting purposes.

Figures 5, 6, 7 and 8 disclose another form of the invention, this form of the invention consists of a holder I3 and a shield generally referred to by numeral M. The holder I3 is in the form of a barrel [5 and side Wings "5, Hi all formed of spring metal and having openings at their opposite ends to receive a pin member ll. This pin member I! is to be disposed through a corresponding notch la in the blade, and in this instance the blade is denoted by numeral I9. The holder I3 is somewhat narrower than the shield l4, and as is clearly shown in the drawings, the shield I4 i constructed with a barrel portion 20 and wing portions 2| as in the manner of the shield 5.

The shield can be shifted to the position shown in Figure 6 and obviously, the shield and holder can be moved to the position shown in Figure 8.

A third modification of the invention is taught by Figures 9, 10 and 11. This form of the invention is intended to accommodate a blade 22 of the type having a longitudinal slot 23 terminating in polygonal-shaped openings 24 wherein a similarly formed opening 25 is located at the intermediate portion of the blade. This third form of the invention consists of a holder 26 having a barrel form 21 and contacting wings 28 for snug disposition against opposite sides of the blade 22. Numeral 29 denotes a sliding shield which has a barrel portion 30 and wing members 3| for snug disposition against opposite sides of the blade 22. Obviously, the parts of the present invention as disclosed in form No. 3 are constructed of spring steel as are forms 1 and 2.

In form No. 3 a pin or the like 32 is disposed through openings in the wing members 28 and through the slot 23 in the blade 22. Obviously, the holder 29 can be slid on the :blade as suggested in Figure 10 and further, the holder 26 can be slid with respect to the blade so as to expose the blade as shown in Figure 10.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. In combination, a blade, a clip-like holder straddling the blade on one side thereof, and a similar sheath straddling said blade on the other side thereof, said holder and sheath ach comside thereof, said holder and sheath each comprising a barrel for housing the adjacent edge of the blade clear of the same, and side wings fitting fiat against the blade, the side wings of the holder and sheath being continuous in edgeto-edge relation to completely cover the blade, and a pin extending through both wings of the holder and the blade, the sheath being slidable on the blade along the same independently of the holder, the blade having a longitudinal slot therein traversed by the pin whereby the holder is slidable on the blade.
