BLADE HOLDER Filed June 2'7, 1927 f vvroes' ETHELE h/Hrr: flrea/v NH/rs Patented June 24, 1930 ETHEL' F. WHITE ANDMYBON WHITE, or Los nnennns, oamronnm BLADE HOLDER 3 Application filed June 27,

' Our invention" appertains to holding devices for razor blades. A. safety razor blade is very useful as a knife if it is provided with a suitable handle whereby it may be 5 held in the hand. c h

Animportant object of our invention is to provide a razor blade handle which may be made at the cost of less'than one cent, but nevertheless will possess certain characteristics which will render it veryhandy.

It is an object of the invention, to provide a razor .bladeholder which isformed from one piece. j j V 7 Another object of the invention is to pro- 5 vide holder in which the blade is locked to it by manipulation. g v

' A further object of he invention is to provide blade holder of the character men tioned in which .the blade 1may be readily 2O placed and removed.

In the following descriptionthe preferred form of our invention will be described. It

is not our intention to thereby limit ourselves to the one embodiment, but intend that our protection shall. extend to the various embodiments in which the invention may be included. I ,1

The inventionwill be described with reference to the accompanying drawing in which: 7 5

Fig. 1 is aperspective view showing the holder supporting a razor blade. f I

Fig. 2 is a view similar to Fig. 1, but showing the holder before the ends are moved into locked position. ,Fig. v3tis a perspective view showing the holder per se before the blade has been 1n-; stalled therein. a Fig. 4 is a section taken on the hne 1-- 1 of Fig. 1. v I

Our invention has 'a metal strip 11 which preferably has the characteristic'of springinetal and may be phosphor bronze. This strip 11 is bent at 12 so that the primary end 13 and the secondary end 1& thereof extend parallel and adjacent .to each other, as illustrated in Fig. 3. .The primary end 13 is provided with a pair of outstruckears 15. The outstruckears 15" have portions 17 which project. substantially perpendicular to 1927. Serial No. 201,638.

the primary end 13 and serve as a centralizing means. Atthe outerends of these portions 17 are engagers 18 which serve as an engaging means of the invention; The engagers 18 extend substantially parallel'to 5 the primary end 13/ The numeral 20 represents a razor blade which is to be supported, as shown inFigs. 1 and 2,. by the holder The razor blade'20 is of thetype of blade made for use in Gillette razors and hasopenings 21 formed therein." The"centralizing means 15 extend through two of the openings 21, as illustrated in Figs. -1 and 2, sothat the outer end of the blade projects beyond the primary and secondary ends. 6 The bladeviswider than the strip 11 so that the cutting edge 22 of the blade rests below the lower edge of the strip 11. As shown, the secondary end 14: has an opening 23 to which a slot 2 1 is connected; and a recess 25 I to which a straight end 26 is connected at the end thereof. After the blade has been installed on the primary 811(113 so that the centralizing mean's15 extend through two of the openings 21 thereof, the secondary end 17 i 14: 'isfmoved from the position shown in Fig.

3 into the position shown'in Fig. 2. Atthis time one of the ears or engagers l8 hasextended through the opening 23, and the other has passed through the recess 25s0 that they" both rest in planes outside the secondary end '14. The next operation is to slide" the sec ondary end 14: upward relative to the primary end 13 so that the opening 23 and recess 25 are disalig'ned from the engagers 18. After this -manipulation the engagers 18 will extendjaround portions 27 and 28 which are adjacent to the face 26 and the slot' 24,,

thus preventing the primary and secondary ends from moving'outward relative-to each, other. The locking means, just described, will hold the bladeto the holder so that it may be used as a knife. In order to prevent the blade from twisting whenused under pressure, we provide a thrust-flange 29 which extends above and may be engaged by an upper edge 30 of the blade. It will be seen that if the secondary end l lismoved downward relative to'theprimar yi end 13 the en s a're free to separaterilool r parts ofthese' ends must beheld in close and the blade would then be released. In

cent to the latch arm 33 is'provided with a.

order to prevent this inadvertent unlocking Y of the blade from thehandle'we provide a latch 'means which includes a latch arm 33 which is formed at the upper edge of the secondary end 14 between recesses 34:. 'The i .upper'end of the latch arm 33 is provided with a projection 35 which is formed by crimping the end thereof. The upper por- 7 tion of the primary 'end 13 which is adjaslit so. as to form a strip 36. 'This strip is outbent as shownso as to providea lug 37. VVhenthe secondary end ll is slid upward relative to the'primary end 13 the contact,. preferably by squeezing the .two

- ends together with the fingers so that the V p latch arm 33-may pass below the lug'37.

When the parts have b een moved into the position shown in Figs. land 2 and the ends released, the primary and secondary ends will tend to move away from each other in p 1 the plane of the latch means so that the latch I arm 33 moves away fromthe primary end 13 andv engages the outer party of thelug-37.

The end of. the latch arm at this time.

movesinto the positionshown in Fig. 4 and prevents a relative sliding movement between the primary and secondary ends.

' This'latch means lretains the two ends in the positionshownuntil they are pressedto gether, as indicated by dotted lines 40 in position as shown in Fig. l.

v Fig. 4, which will permit the-end 35 of the 'latch'arm 33 to move downward inside the lu'g'37.

uThe inventlon also provides a means for preventing the primary and secondary ends from moving longitudinally-with respect'to each other when the holder is in latched "comprises a notch' 41 formed in the upper f edge of thesecondarystrip into which an to make holders onthe same principle but i being in a slightly difi'er ent design. example, with little redesigning'it is pos-- 1 primary: and' secondary ends in a locked ear/l2 formed at the upperend' of the primary strip extends when the parts are in the position shown. The engagement of the i ear in thenotch prevents thislongitudinal nlovement; r

\ As previously pointediout, we'do not wish to be limited to the particular form of hold- This means very important since it makes it possibleto provide 'a blade holder very cheaply. Even whenmaking the holders in smallrlots, they cost less than one cent each. Another very 7 H 'for locking the primary and secondary ends 7 important part of the invention is the means "A holder for supporting a razor blade with one edge thereof in exposedfoperative position, said holder comprising a 'strlp of resilient metalbent upon itself to form av handle, the outer ends of the strip forming blade holdlngmembers, means foriholdlng the members together with a razor blade. therebetween, sa d means comprlsmg an 111- tegral hooked ear on one of sald members,
