'RAZOR BLADE AND NIL FILE HOLDER Filed Aug. 1. 1928 Patented Feb. 4, 1930V PATENT OFFICE g OLIVER P. GREENSTREET, Fy OWNSVILIE, V:MISSOURI RAZOR-BLADE AND nain-FILE yHOLDER Application mea August 1e, 192s. serial No. 300,076. l

yThis inventionrelatesto razor blades for f 4use as erasers, knives, scrapers, etc., the object being to provide a holder of very simple construction which will permit the use of discarded or new razor blades for scraping f' paints, pare corns, cutting thread, and the like, and which is vso constructed that the sharp edge oie the razor bladewill not be dulledfbut will be prevented from coming in 51o Contact with the shield or sheath within whichthe razor blade is normally fully cony tained. y j

Another objectpisto provide meansrwhereby the blade may be projected either wholly or partially, and another object is to provide a projectable and retractible finger nail iile v j mounted in-said sheath.

lMy invention is illustrated in theaccompanying drawing, wherein 2o Figure 1 is a side elevation of one form of my razor blade holder;

f Fig. 2 is a longitudinal sectional view 'thereof showing a razor blade in place therein; f

y Fig. 3 is a section on the line 3 3 of Fig. 1 a

.f Fig. 4 is a side elevation of another form of my device; c c

Fig, 5 is a side elevation of a form like that shown in Fig. 4, but showing `a nail file mounted therein;

Fig. 6 is a section on 5; and Fig.'7 is a fragmentary section on the line 7-7 of Fig. 5.

v In Figure 1, I vhave illustrated a very simple form of my invention, wherein 10 designates a'sheath of thin sheet metal, this sheath being so formed as to provide an enlarged bead 11 at the back of the sheath `and aV small bead 12 along the edge of the sheath, this small beadfbeing defined by a constricted neck 13 extending along the whole length of the sheath. The sheath is open at one or both ends and is adapted to contain a razor blade such as the blade A. The sheath is preferably made of resilient metal so as to press against the blade and hold it firmly in place against any tendency of acthe line 6-6 of Fig.

5o cidental dropping out of the sheath. One

side wall ofthe sheath isformed withv an elongated slot 14 p'ermitting'the introduction of a finger so as to permit the blade A to be projected. either wholly or to a greater or less'eXtent from one end of the sheath.

Preferably the holder or sheath will be longer than the blade A and the sheath at one end will be longitudinally slitted at its` edges, that isa-long the beads 11 and 12 as at 15,r so that the bladeA may be taken out ot' the holder and inserted in said slits so as to extend Vcros'swise of the holder, as shown in Fig. 1 in dotted lines, to thereby permit the device to vbe used for scraping paint from glassn or for a large number ot other purposes. I i

VIn Figure 4, I illustrate another form whereinfth'e blade is projected by means of a button,Y 16 .having sliding engagement through a slot 14a, this button bearing against an end of the blade and by this means the blade may be readily forced out to any desired extent.

In Figure 5, I illustrate in connection with the blade holder or sheath a nail file 17 operating within the bead 11 of the sheath and bearing flat against one face of the blade A. The bead 11 is shown as longitudinally slotted at 18 and the button 19 is attached to the iile 17 so that the file may be projected or retracted, of course, independently of the projection or retraction of the razor blade A.

It will be seen that my holder permits old razor blades to be used as cutting or scraping tools, that it provides a convenient handle for the blade when so used and that when out of use the blade is entirely enclosed within a sheath so that the blade may be carried in a pocket without danger of cutting the pocket. Furthermore, it will be noted that the sheath does not bear at any point against the sharp edge of the blade but that this sharp edge is fully protected. As illustrated the devices as shown in Figs. 4 and 5 are also formed with the slots 15 whereby a razor blade may be disposed crosswise as shown in dotted lines in Fig. 1, so that it may be used as a scraper.

What I claim is z- 1. A holder for razor blades comprising a sheath open at one end and adapted to contain the razor blade, the sides of the sheath being formed to frictionally hold the razor blade Within the sheath, that margin of the sheath Which engages the edge of the razor 5 blade being contracted to tightly fit on each side of the beveled edge of the blade and beyond this contracted portion having a bead to protect the fmitt'fing edge lof the blade., the sheath being longer than the blade,' and i 10 means whereby the blade may be projected or retracted tlrroughthe .open end otthe' sheath, the sheath at one end having longi-I tudinal slots at its opposite edgesto permit -the razor blade to be disposed transverselyp-, Y

15 of the sheath and in said slots; i Y

.2. Arazorblade holder formed to provide a .sheath of thin .metal open at its ends and p Within which a azor blade is rictionally held, the opposite Walls of the sheath being 1zo longitudinally .slotted whereby the razor blade may 'beprojected beyond lthe shea-th,

Y the sheath along one .margin being formed W'ith'a relatively Vlargexbead and .adjacent its opposite margin vbeing contracted so `as Ito m, bear `against the 4beveled edge of the blade and beyond said contraction being formed with a bead to .protect the cutting edge' of the blade, the sheath being longer -than the blade and at [one end having longitudinal yslots 30 along. the ,opposite edges of theshea't'h Whereby to permit the razor blade to be disposed transversely .of the sheath landinto said slots. In testimony whereof I .hereunto airixmy signature. n Y 35 v OLIVER P. GREENSTREET.
