yReferring to Fig, 1, I0 indicates in its entirety a complete .razorfstructure which comprises a housing Iiwforthe .collapsible razor. 2.. The l0 collapsible razor l2 comprises a handle- I2 and a raaorfhead I4,l consisting of a clamping inember I5, `blade I6 `and-guaJd-II. The housingjl preferably 'comprisesaVV tubular 'member which may be formed oi fBakelite. or other suitable Il plastic or metallic substance, andwhich issimilar in shape .and `size toithe-` modernfountain Pen v f The housing H is provided witha cylindrical bore I8` which is closed at onefend lI8 in the embodiment of Fig. land the other. openend maybe closed -bya closure knob 20,1: The closure 1 knobk 20 is provided with asubstantiallycylin- Y drical portion2| of a size complementary to the bore A|8/so that the cylindrical -portion 2| Vhas a u close frictional nt inthe borre capable pt hoiding the ,parts in the position of Fig, l. If, desired, .however,both the cylindrical portion 2|` and the adjacent part of bore I0 may be provided'with complementary threads. The cylindrical member 2| is rounded or tapered.at 22 so as to aidfin centering theplug inthefend of thebore I8, andftheplug is preferablypr. videdv with a bore 23 for receiving the reduced end of the handley i3 which has an annular )l shoulder abutting against the plug. Y

Adjacent the cylindrical portion 2 I 'heclosure plug 20 isenlarged at 25 sothat-its outer surface is flush with the exterior o f housing Il. andthis lcylindrical surface may be knurled onmadeo polygonal in shape tflfacilitate grip of thev plug by the fingers. f The extreme end 26 rof the plug may take any ornamental Shape, but intheembodiment of Fig. l it is extended and rounded to'provide a, convenient handle. l 45' The handle I3 comprises a metal-riielnber V'which may ,be provided with aiapered shank 21 and the upper end 'of the handle may bel provided with an elongated cylindrical bore 2l which is threaded at its extreme end 2s. A so' transverse bore l3|) communicates with.l the bore -28 and lprovides a socket for lthe shank 3| kof the razor head when the razor is collapsed, as

shownV in` Fig. -1.v l I n The threaded portion 29 of bore 28 is threaded lo i adapted .to receive Vthe curved, resilient spring lugs I4 on the retaining member 34.

Referring to Fig. '6, this is e pian view or nieblank used in making the retaining member-34 which may be constructed of any resilient lsheet metal, preferably some -non-corrodible metal such as spring brass or bronze. 'I'his blank has A.

its rectangular body 31 bentA to form a cylinder, asshown in Fig.' 5, and the twolowerlugs 38 are bent out atright* anglesl for the-purpose .of retaining member 34 inits socket, asewll -be described in greaterdetail hereinafter.

The longer lugs 36 at the top of the: blank are each curved inward and outward, as shown in mg. 5, to'"pro'vide-resuient gripping angers whichV engage in the groove` 33 'underneath *the ball member I2, as shown inFig; il; The width of the'blank 3l is such that it may be inserted inthe bore by pressing: the circlet together until the'lugslpass ltheb'orefilion the right` handfside. When the retainingfmernber 34 reached its'final `positiomjthe lugs 3l "engage insidel the bore 2l and'1.*ei'man'entl'y holdithis.

retaining-f member in the position of"Fig. if, 'Ihe shank 3l fof the safetyrazonhead may then be inserted inthe cylindricalbore 39 4of the retaining inelnbei" until "the head 32" is Referring'tofFig. 4, the 'details' of the razor are shown in this figure." The handle il vvhas already described, as weilas'the -shanir 3l or me clamping member is. VThe clamping member comprises a i'iat metal member recdownwardly inthe saine direction as the shank 3l but are spaced" from lthe lshank 3| at each end jof the guard 'and are also located laterally from the shank ll in such mannerthatliigs 4l engage the side offthe handler when theshank Iijisfin the 'bores' 30, It( y'Ihe lugs 40 thus prevent rotation of the headV assembly when lthe parts are in the position o f Fig".` 1. i Y

The razor 'blade comprises 'a 'tempered at resilient blade rectangular in lplan andhaving a\n centrally located 'aperture "4| for receiving shank 3|."Rectangular apertures 42 'are suitably located at each end and towardthe back of the .blade yto receive' thelugs'4ll.l In theV present embodiment a single edge vblade` is member provided' .with a registering circular f aperture 44 for receiving the shank 3i and with shown, the edge b eing at 43, but 4it will be obvious that the razor might be vmacle double 'rne guard member n comprises o sheet metal the registering elongated slots or apertures v45 for receiving the lugs 40. A downwardly turned the bore 29 an nsnge 4l is provided at its forward edge lor guarding and protecting the blade I 4 and when the blade, guard and clamping member are slsembled with handle Il. the blade is clamped between the clamping member Il and guard I1 by means of threads on Il.

If desired, `one of the lugs and its complementaryA aperture may be made slightly wider than the other to prevent improper assembly fof the-'head lion the guard'l'l. 'I'he apertures 42111` the blade may be made of the same width as the widest lug 40, since improper l-assembly of the blade on the head I6 is precluded because of the position of the stud Il.

When it is desired to place the razor in its casing, the` head assembly lis removedfrom the handle and shoved into the bores I4. 3l where thevhead 32 is 'gripped by springvngers 34. The `complete collapsed assembly may then be slid into the housing Il, as shown in Pig. l. Referring toFigs. 'l tov9, this is a modification in which the detailsof' the lower part of the housing may-besubstantially as described. The upperend of the housing is provided with 'a tubularextension '41 having a cylindrical bore 4lwithin'rwhich may be disposed a supply oi' shaving soap 49 yand a stypticpencil ,whlch is held by the closure 4cap SI. I'he closure cap 5Iv may be," similar/in structure tothe closure cap '20 having 'a cylindrical portion l2 which has a close'V frictional fit with theL interior of the bore'4l. `f 4 z In this embodiment me handle n is provided with an elongated bore 53 for receivingy the compression spring-M. 'I'he bores 30v are notprovided with" the spring retaining member 84 but a counterbore 55k slidably receives a headed plunger se, ythe need s1 being disposed in boxe 53 and engaged by the 'spring 54.v "'iheplunger 56 forces the shank Il toward the upper side'of vme vbore nso therme edge ssj of kthe mooie surrounding-bore'` "engages beneath the n.: Immie'embouiment e aideront forni of guard 59 is employedfhavingltwo cut-out Vpoitions 6 V0,but theA shape and structure of lthe guard may b e varied considerably without departing from the' spirit oi' the invention. It will thus be'obsei'ved that I have invented a new, collapsible safety'razor which may be housed in a casing no larger than the ordinaryA fountain pen.

- The'parts are "assembled for use/by removing theclosure plug 2l and pressing upon the head 32 with the thumb'to remove the shank Il from bore 30. The rivthe shank Ii isI threaded into the position of Fig. '2;

When the partsnare and housedl in 55 used with its mmm -the casing li there .is -no danger'of 'rattling or damagentothe'blade' and theparts are securely held together'andirotatitonis prevented bythe lugs 40. By means of the improved housing of Fig. 'Tall Vof the ess'egntiali supplies needed 'for shaving may be carried 'in' one tubular housing, thereby eliminating the necessity for carrying'a number of bulky toiletarticlesl u Y, `From the foregoing description it will appear that I have invented a.l very compact razor which can without inconvenience be carried by a person when traveling; and used with facility. The Ahead of the razor is lvery narrow, making it possible tolshave very close on'the various parts of the-"face which are frequently exceedingly diflicult to shave with an ordinary'razor. For

example, the portion of the upper lipdirectly be- 15 heath the nose may be readily shaved. and in fact the razor blade and head is so small that it may be used to remove hair growing partially within the nostrils. The razor is also very convenient for use in shaving the arm pits and has numerous applications in connection with shaving done preparatory to surgery.

As illustrative of the compactness of the razor, the outside diameter of the tube I of the embodiment shown in Fig. 1 is 1/2, and the blade is approximately 1% in width.

While I have illustrated and described preierred embodiments of my invention, many modiilcations may be made without departing from the spirit of the invention and I do not wish to be limited to the precise details set forth but desire to avail myself of all changes within the scope of the appended claims.
