3 Claims. 3

This invention relates to safety razors and is particularly directed to an improved form 01' razor employing a ribbon-type blade.

The principal object of this invention is to provide a novel form of safety razor employing a ribbon-type blade in which supply and take-up coils are mounted on a carrier for attachment to therazor head as a unit.

Another object is to provide a razor of this type having supply and take-up spools positioned below a razor head together with clamp means above the head which is movable to hold the ribbon blade on a blade seat provided on the top surface of the head.

Another object is to provide a novel form of take-up spool for a ribbon blade razor.

Other objects and advantages will appear hereinafter.

Referring to the drawings:

Figure 1 is a side elevation showing a razor embodying my invention.

Figure 2 is a front elevation partly broken away taken substantially in the direction 22 as in dicated in Figure l.

Figure 3 is a sectional side elevation partly broken away taken substantially on the lines 3-2 as shown in Figure 2.

Figure 4 is an exploded perspective view showing the manner of assembly of various parts of the razor.

Figure 5 is a transverse sectional view of the supply container for the ribbon blade.

Figure 6 is a perspective view partly broken away showing construction of the take-up spool for the ribbon blade.

Figures 7 to show a modified form of my invention in which the supply and take-up spools for the ribbon blade are mounted on a carrier, which carrier is adapted to be attached to the razor head as a unit. Figure 'l is a side elevation; Figure 8 is front elevation partly broken away; Figure 9 is a sectional side elevation showing the manner of attachment of the carrier to the razor head; and Figure 10 is an exploded view-illustrating themanner of assembly of the carrier and razor head.

Referring to the drawings, the safety razor shown in Figure 1 and generally designated It may be provided with a handle ll having an in clined head l2 rigidly secured at its upper end.- A cover it overlies the head I! and may be provided with a central sleeve ll slidably mounted within a recess I. The sleeve is interiorly threaded to receive the upper end of the rod it which extends upwardly through the handle and which is secured to the knob il. Rotation of the knob il serves to move the cover It with respect to the razor head 12. The forward edge 68 of the razor head l2 may be provided with the usual comb teeth, and a pair of upwardly projecting guide pins 69 are mounted at opposite ends of the comb i8. Additional upwardly projecting guides 20 are provided on the razor head, and the upper surface of the razor head extending from the comb l8 to the location of the projecting guides 20 constitutes a seat surface 25 for a blade. The surface 2' is interrupted by openings 22 which extend through the razor head.

A ribbon blade 23 of metallic flexible material is provided with a sharpened portion 26 along one edge thereof. The blade 23 extends from a supply shell 25 to a take-up shell 26, and the blade is coiled within the shells as shown in Figure 5. The blade 23 extends outwardly from the shell 25 through an aperture 21 and extends over the blade seat 2i on the upper surface of the razor head l2. The blade then extends into the aperture 39 in the take-up shellzt, and is wound on a spool or reel 38 provided with an exposed knob 3i. Ratchet means comprising a resilient pawl 32 formed from the body of the shell 26 engages ratchet teeth 33 formed on the reel 38 to prevent reverse movement of the ribbon blade 23 with respect to the blade seat 2|. The supply shell 25 may be provided with a cap 25aand the take-up shell 26 has an opening in'one end to receive a central bearing 38a provided on the reel 38. The extreme ends of the blade seat 2| are rounded as shown at 28 to avoid overstressing the ribbon blade as it enters and leaves the blade seat.

Means are provided on the razor head for holding the

shells

25 and 26, and as shown in the drawings this means includes a pair of spring clips- 29 and 30. The shell 25 is held within the spring clip 29 and maintained against displacement while the shell 26 is similarly supported and confined by the spring clip 30. Preferably a leader portion on the ribbon blade having an unsharpened edge is provided so that the

shells

25 and 26 can be installed within the

spring clips

29 and 30 without danger oi. cutting the fingers of the user. When the ribbon blade 23 is installed in position on the blade seat 2! the knob 3| on the take-up spool 38 is turned to bring the sharpened edge 24 into operative position on the blade seat 2!. The handle knob I1 is then rotated to bring the cover-i3 downwardly with respect to the razor head and to engage the forward end 34 thereof with the ribbon blade 23 in a order to hold it tightly against the seat 2 I. when through use a fresh'portion edges 2! of the blade seat 2 I.

3 edge 24 of the blade becomes dull of the blade may be brought into service by first lifting the cover I! and then winding the knob 2| to withdraw an unused length of ribbon blade 23 irom the supply spool 2|. The cover is then returned to clamping position by actuation of the handle knob l'l. Movement of the cover It with respect to the head i2 may be guided by means of the lateral pins 35 extending through the vertical slots 36 provided in the side walls of the cover. The forwardly extending portions 31 of the cover side walls are effective as guards for shielding the sharpened edge 24 of the blade 23 between the locations where it emerges from the

shells

25 and 26 and locations where it contacts the curved the sharpened when the supply of ribbon blade come exhausted the

shells

25 and 26 may be discarded and new shells connected by a fresh blade installed.

In the modified form f my invention as shown in Figures '7 to 10 inclusive, the razor handle Ii, head l2, cover i3. knob i1,

shells

25, 26 and blade 2! may take the form illustrated and described in the foregoing figures. This modification differs primarily in that the shells are mounted in spaced position on a removable carrier 50 which may be attached to the underside of the razor head i2. The carrier 50 includes a spaced pair of curved gripping elements i and 52 adapted to support and hold the

shells

25 and 26 respectively, together with a central bridge element 53 extending therebetween. A pair of fingers 54 are mounted under the razor head i2 and attached thereto by means of the rivets 55. These fingers resiliently clamp the bridge 53 against side of the razor head I2 and disassembly is prevented by means of engagement of a protuberance 56 on the ends of the fingers adapted to enter the recesses 51 provided on the bridge 53. The fingers are. sufficiently resilient to permit installation and removal of the bridge in a direction transverse of the length of the blade 23.

The operation of this form of my invention is substantially the same as that previously described. The cover i3 is moved downwardly to clamp the ribbon blade 23 against the blade seat 2 I. When the supply of sharpened ribbon blade has been exhausted the

shells

25 and 26 may be disposed of as before and new shells installed on the carrier. If desired the carrier and shells 23 has be-' the undercanbeformedasasingleimiaandinthiscase the entire unit would be discarded and a new one supplied.

Having fully. described my invention, it is to be understood that I do not wish to be limited to the details herein set forth, but my ,invention is of the full scope of the appended claims.

I claim:

l. A safety razor comprising in combination: a razor head having an upwardly facing blade seat, a flexible ribbon blade on theseat, one end of the blade being coiled in a supply shell and the other being secured to a take-up reel; a spacer member extending between the shell and take-up reel and adapted to maintain them in spaced relationship; means on the razor head for releasably securing the spacer member to the under side thereof; the shell, reel, blade and spacer member being insertable as a unit into operative position on the razor head to position the blade on said seat.

, 2. A safety razor comprising in combination: a razor head having an upwardly facing blade seat, a flexible ribbon blade on the seat, one end of the blade being coiled in a supply shell and the other being secured to a take-up reel; a spacer member extending between the shell and take-up reel and adapted to maintain them in spaced relationship; spring fingers on the underside of the head for releasably securing the spacer member thereto; the shell, reel, blade and spacer member being insertable as a unit into operative position on the razor head to position the blade on said seat. 1
