l .My invention relatesto magnetic razor conlio ditioning, my object being to provide a simple and effective means of producing ormaintaining Va good edge on a razor blade by magnetic influence. How this and other advan tages may be realized through my invention will appear from my description hereinafter of certain devices conveniently embodying it. In the drawings, Fig. I is a tilted View yof a device suitable for the purposes of my invention, including a magnet in a case and a keeper for the magnet associated with a cover for the case,-the cover and case being oppositely tilte Fig. II showsV a longitudinal vertical section through the device with the cover and Akeeper in place on the case and magnet.

Fig. III shows a longitudinal section of the magnet and case alone, with a safety razor blade Vunder treatment by the magnet in one manner. Y

Fig. IV is a similar view showing a diierent manner of treatinga razor blade.

' Fig. V is a view similar to Fig. III, showing a somewhat dierent construction.

Fig. VI shows a longitudinal `section through a cover and keeper for the case and magnet shown in Fig. IV.

ltain the cover 12 in proper position.

Fig. VII shows a transverse section of the device with a razor therein under treatment. As shown in Fig. I, the device comprises a magnet 10 of bar form in a case 11, and also a cover 12 for the case 11 associated or equipped with a keeper or armature 13 forl the magnet 10. In the present instance, thev case 11 projects above the magnet 10, and the ends of the keeper 13 engage inside the upstanding case, in its corners, so as to main- The ends ofthe keeper 13 are turned or bent downward at 14 and 15, so as to reach and engage the ends of the magnet 10. The magnet 10 may be a permanent magnet and the keeper 13 a strip of soft iron; while the case and cover 12 may be of any suitablenonmagnetic material, such as a moldable comf position or compound like bakelite. As shown, the magnet 10 is secured to the bottom of the case 11 by rivets 16, andthe keeper 13 is secured to the cover V12 by rivets 17. Y As `ing on the'other end of the case 11.

shown in'Fig. II, there is slightclearance b'e-V d.

tween the upper edge of thecase 11 and the lid 12 when `the keeper projections 14, 15 rest on themagnet 10.

As shown in Figs, I', II, III, and IV, theV ends of the magnet 10 Vare preferably provvided with transverse engagementv means for aligning and maintaining a 'safety razor'blade y 1n proper treatingV position with reference to the m agnet,such means being shown in the form of saw- tooth grooves 18,19, across the ends of the flat magnet bar. A lso,1one end' of the magnet 10 is bevelledas at 2O to afford a more suitable treating face orsurface. The keeper end 14 is squared ott, andthe end 15 bevelled in correspondence with the niagnet'bevcl 20, so that both 'keeper ends shall make good contact with themagnet ends over 4 ,f ampleareaa Figs. vIII and Iv-iuuame theus'f the device, with'the cover 12 "and keeper`13'removed, to treat a safety razor'of familiar type and form, comprising a blade 21, a guard 22, a clamphead'23, and a handle 124, .with adv justable connection to the clamp head.

As hshown in Fig. III, the ordinary shaving tension on the bladel 21 has'been relaxed, so as to allowfit .to resume its normal flat form. The razor has been laid on the device with the'usual pronged edge of theV guard22 resting inthe groove 18 andthe handle 24 rest-V Accordingly, the blade 21 standsvnormal tothe surface'of the magnet end beyond the groove 18, .with its cutting jedge very closeindeed sovr to Vthe magnet,yetv outgof lcontact therewith. After one edge Yoffthe `blade'2`1 has Vbeen f treated in this manner .fora period of, say,"

halffa .minute or more, the razor vmay be reversed and the other edge similarly treated."

While the blade 21 may be'left.undertreat ment much longer than' the shortperiod above mentioned, yetthis short period will 'generally suffice to produce most, at` any rate, `of the possible beneficial .eii'ect onrthe blade. 'd

Figs. V, VI and VII illustrate a device differing from that ofFigs. I'to IV in being i longer and deeper, so as `to contain a razor while under treatment. In thefpresentin'.- stance, the cover 12ae'xtends some distance down around the keeper or armature 13?, instead of being a mere flat piece as 1n Figs. I

Vand II. The downturned ends 14a and 15a of the keeper 13@L are correspondingly longer, so as to afford depth forl accommodating the Whole razor therewithin When the cover l2a is on the case 11a. rlfhe case 11EL is also'prQ- vided with supports for the razor, `in the form of transverse blocks 26 With centrally located curved notches 27 (Fig. VII) to accommodate the razor handle 24. The cover 12st has similarly notched blocks 28 to fit over the handle 24 and hold the razor in definite position in the case 11,-i. e., `the, position required for treatment 'of the edge of the razor blade 21 in substantially Vthe same Ways as -illustrated in Figs. I II and IV. vThe length or depth of the downturnedarmature ends 14a, 152L is preferably such that the up per prongs of the guard 22 just about engage (or fail to engage) the keeper 13; and thus theupper edge of the blade 21 Will lie very close to thek keeper 13, so as to be affected by the induced i magnetism therein. When treated as in Fig. III, the blade 21 lies normal to'both magnet 10a and keeper 12a; While when treated .as inFig. IV, the blade is approximately normal to the keeper, as Well as truly normal to the bottom of the groove 19a (FigV). .y I i Having thus described my invention. I claim:
