Referring now. to the drawings in which the various parts areindicated by numerals:

Fhe razor includes a tape-like strip of thin flexible metalhavingits opposite edges sharpened to form a long narrow double edge blade I B, which ishoused in a .hollow body, including a head portion l8 and a handle portion 20, and-a complementary magazine. 22 which telescopes within the bodyv portion.

Initially the blade is housed in a coil 24 within the magazineunused portions l6A of. the blade being successivelywithdrawn from the coil and fedacross. the head portion l8 for use, the used portions [6B being concurrently returned into the storage section of themagazine, and there formed .into aused-coil 24A.

Thehollow body 20 is substantially of rectangular cross section with side Walls 20A, and edgewalls 20B,- anis open at its lower end. The upper end or head portion iii of the body includes a blade support 28 which is arcuately curved in cross section, and extends beyond the cutting edges of. theblade l 5 and slightly beyond the side walls ZllAto form guards 28A. The blade support is provided with longitudinal slots 2813 which underlie and expose the cutting edges of the blade l6 foruse. The slots in cross section extend downwardly and outwardly and discharge exteriorly to the body below the guards 28A. Im- .mediately adjacent the edge walls'ZflB the blade amaooc support 28 is cut away, as is shown in the upper right corner of Fig. 5 from which the guide sprocket has been removed, to form slots C, and the sprocket chambers 20D. Overlying the blade is a holding member which holds the blade against the blade support 28, the member at its opposite ends curving arcuately downward and connecting into the edge walls 203.

In the sprocket chambers 20D the support member 28 is provided with bosses 32, which carry shafts 34, and pinions 36 which are centrally disposed between the side walls 20A, the shafts being positioned to project the teeth of the pinions through holes 38 alined along the longitudinal center of the blade strip, and so engaging to aline the blade strip [6 as it leaves the mesazine 22, passes across and leaves the head IS.

The blade magazine 22 includes side walls 22A and edge walls 223, the latter walls being joined at their lower ends by an arcuate continuation 22C which forms the bottom end of the magazine, the upper end of the magazine preferably being closed by a top 22D. Within the magazine an arcuate continuation 22E of the bottom end 220 establishes a chamber 22F for the reception with openings 22G adjacent the edge walls 22B for the exit of the unused blade portion [6A and the entrance of the used portion lfiB of the blade strip. Preferably a guide member 22H restricts deflection of the blade portion {5A between the coil 2% and the openin 22G and a similar guide member, not numbered, may be used adjacent the opposite opening 22G through which the used strip IBB reenters the magazine. The edge walls 22B are provided with longitudinal slots 22.] extending upward from approximately the center of coil 24 into adjacency to the top of the magazine for a purpose to be hereinafter disclosed. The side walls 22A carry hubs 48 which journal a shaft 42 on which is mounted a sprocket 44 about which the coil 24 of the blade is formed, the sprocket having projecting teeth which engage the central holes 38 in the blade and prevents its lateral displacement and consequent contact of the blade edges with the sides of the magazine. The side walls of the magazine are also apertured to remagazine and the body are of light weight metal or plastic and that the side walls 22A of the magazine in the vicinity of the lugs 46 may be inwardl deflected to effect release of latching engagement of the lugs 46 therewith when it is desired to remove the magazine, deflection of the side walls of the handle permittin outward deflection of the lugs during the subsequent removal.

Preferably both edge walls 2GB of the handle intermediate their length are outwardly deflected to form charmelways 48 which are respectively provided each with a longitudinal slot 48A positioned to aline with a slot 22J of the magazine 22 when the same is in place, the slotted channelways slidably mounting manually operable blade shifters and 52 having toothed portions 50A, 52A, which extend through the slots 22J of the magazine into engagement with the holes 38 of the blade strip portions [6A and |6B respectively. The teeth of the toothed portions 50A, 525 are of triangular shape and are respectively faced for shiftin engagement with the blade holes only during upward movement of the shifter 50 and downward movement of the shifter 52 whereby to concurrently move the blade portion I6A upward toward the head l8 and withdraw the blade portion 163 from the head and feed it into the storage portion of the magazine. Preferably the slots 22J of the magazine and 48A of the channelways are of length to allow proper shifter movement to accomplish a complete cutting sector shift of the blade in the head.

Initially the razor is sold as a unit including the body section and blade equipped magazine section, ready for use.

The shifter 58 is retracted bringing the tooth portion 50A into engagement with the holes in the blade strip and the shifter is subsequently moved upward the length of the slot 22J shifting the blade upward through the opening 226 toward the sprocket 35. The shifter is again retracted, and the operation repeated advancing the blade around the first of the sprockets 36 and across the head until a length of blade has been advanced into cutting position, and preferably into engagement with the second of the sprockets. When after use, the razor requires a fresh section of blade, the shifter is again operated shifting a new cutting length into position in the head and forcing the used portion IGB downward along the edge wall 20B of the body and through the opening 22G into the magazine 22, and thereafter both the shifter 50 and the shifter 52 may be jointly operated, the first to position the blade toward the head and the second to concurrently aid in withdrawing it from the head. Eventually the used portion [6B of the blade is forced downward and into the chamber 22F in which by subsequent advancement the used section is coiled.

It will be understood that in advancing the blade it is usually necessary to advance the cutting edge less than the full length exposed for use, since ordinarily the blade in the central portion of the head does the majority of the work. Under such conditions it is obvious that only such movement of the shifters need be made as is found necessary to accomplish the desired shift.

When the entire strip of blade has been used and the used blade is housed within the magazine the side Walls 22A of the magazine are deflected in the vicinity of the lugs 46 to release the lug engagement and the magazine withdrawn, the subsequent outward defiection of the lug carrying portion of the body walls 20A permit-ting completion of the removal. The magazine removed is thrown away and replaced with a new replacement unit and the operation repeated.
