1 This ainventihnzis'concerned with a folding razorit beingia general; object of the invention to provide a razor which is'simple andiconv-enient'lto use,'of practicalinexpensive construction, and such thati it cambe readily 'folded' into compact fornzr for convenientzstora-gez or transportation.

It is= a: 'generalzobjectfof this: irrvention toprovide: a razor which ca'nxbausedzl to; advantagevby travelersaorv'byrpersonszhaving but: occasional use for agrazonand whowish torcarry; airazor on-rtheir person, with; lug age, onto store it in alimited space. The construction provided by :the presentinvention lends itself to the'produc-tionof a razor somewhat smaller thamtheusual-or conventional razor, making.- it practical eitherasa razor; forgeneraluse 'by men or for occasional use; Joy-women.

It: isanother object of the present inventionto-prov-ide arazor f, the general-type, referred to embodying a bladecarrying, head: pivoted: to a stemon which there is, aebase :cooperating with a hollow or shelllike body which body is applicabletothe-baseon-thestem inv a manner either to house or encase the 1 head when. it: it. is folded to the stem or to projeetiromthestem forminga handldby' which the razor, eanbe conveniently operated.

A further. object I ofv theinvent-iom is to provide a razorrofithe, character referred to having asimple, practical inexpensive construction by. which thebaseofvthe stemis=related tothe body. which forms the case or handle, which. construction enables the body to, be. readily engaged with or removed from the ,baseand yet effectively. .couples the'body and the case whenathe body. is, serving toiencasemthe head. or. when the, body is: acting as a handle for. the structure.

Another object ofithe invention, is to provide a razor of the general characterrefe'rred toembodying but" few simple, inexpensive parts making' it practical andinexpensive of construction.

Thevarious objects and" features of our inventionwill befully understood from the following detailed description of a typicaLpreferred' form and application" oithe invention, throughout which descriptionieference is made to the accompanying drawings, in which:

'Fig;'1 is a perspective view'of' the-structure provided by the present invention showing parts broken I away to illustrate details 1 of construction and-showing the body oflthe structure inposition servi'ng as a": case 'or housing" for" the: working parts; Fig;-2- is a perspective view ofthe-structure'embodyingthe invention showing itimwork- 2 ing' condition, that is, with the: bodytfextending fromithe stem to serveras a: handle 1 by 'whi'chthe head may be manipulated.

Fig. is: a verticalzsect'ional" view of the structuregbeing: a view" taken in ithe general direction indicated by line id' li 'on' Fi'g; 2. Fig. 5' is a t sectional 'view'taken as 'e indicated by line5--5s' on Fig. 4. Fig. 6 is 'a -perspective view ofthe-"body taken "a-l'oneaorapart iromtthe other portions I of the structure and' 'showing it in the p0SitlOn. in-T'Whi(th it appears: i'ni liig'. 2 of the drawings,'and Fig. 7 is aplan sectionftak'en substantially as indicatedibylihe *T- T on Fig. 5.

The: structure provided Jby'the present invention involves, generally a blade A; ahead B carrying" the blade; astemC, means D pivotally, connecting the head. to the stem, a base :Eon the stem and a'body.=.F'appli'cable to the: base to act as a housing or "case for" the head;- andstein, as shown in Fig. 1' or' as ahandle continuing or Projecting from the stem a's shownt in'Figs. 2:

and 4. The'blade'Aas'usediinrcarrying outat'he present" invention may vary' widely iform or design. The particular blade illustrated is of 'simple form, being in effect a: 'simple'flat' rectangular blade with longitudinal side edges l"0"'sharpenedto'act asrcutting orworking.edges. Atone end of the blade oppositely pitchedx'or: inclined notches H "enter the blade leaving: a tab l'2which forms a grip by which the :blademay 'bemahipulated or handled" relative to the headsB. Atithe othereend ofithe biade avdeep notch' or: recess i3 enters" the blade midway between the: edges I10. and extends :a substantial distancei-inrthexblade', in fact, throughout the greateriportion oi? the lengthxof: the blade, sothat the; blade is; intefiect, U-sh'aped'in plan' configuration, as shown imFig. 7 of the-drawings; The deep-notchior'recess1'3 provided inthe blade is'to accomnrodateiorcooperateiwith the head B, as'will be hereinafter described. 7

The 'head *Bis 1 a rigid unit free: of working or relatively moving parts. and it .is preferably formed of two elements or'sections and Y; which arerigidly'joined or connected together; The section Y of theiheadis in the nature ofa plate elongate inform. and generally 'rectan'gu lar in plan configuration to conform to the general shape oftlqe bla'de A. The plate section Yhas a topifa'ce' M" on" whichitheiblade A rests or is confined, and it has" notched" or serrated'longitudinal edges where the'sharpene'd-edges l'fl'of "theabl'ade' A I occur. The desired serrated xorr tcothed effect is gained at the edges of the section Y by providing a series of notches I5 in the plate section from the edges l6 thereof.

Section X of the head is in the nature of a plateY and the cap X and which serves to space the faces l4 and I8 apart o that the blade A may be slidably engaged between them to a working of the drawings. To thus limit the operation of position such as is shown throughout the drawings. The spacer is a narrow elon'gatecentrally located part that extends between theplate and or to be the same as the deep notch I3 in the bladeA, allof which enables the blade to be slid betwe'enthe plateand cap to a position such as is shown in thedrawings. 1

Inthe'course'of engaging the blade between the plate and cap it is flexed'or bent'somewhat so that it corresponds to the curvature of the faces Hiand l8 and when the blade is in place its edges 10 are'in'proper working position'relativerto the jnotched edges l6 of. the plate Y. In accordance with the preferred form of the. invention the spacer l9 isdntegrally 'formedlon orwith one section'of the head. In the .-'case shown in the drawings it is integral with the cap :section.

.tThei head further involves .means rigidly or permanently coupling the two sections 'X and Y of the head. In the case illustrated coupling ,pinsflor lugs. project from one section of the head to be tightly engaged "insockets 2| in the other-section of the head. The lug projections 20.

areshown occurring on or projecting from the section'X and as such' as toproject from the spacer l9 that occurs on section X. In' this case the sockets 2| are located in the section Y- and are spaced or positioned to properly receive the lugs. "It will be understood that the lugs'and sockets may, in practice, be proportioned so that when theyare forced 'or engaged together, as by pressure, the sections X'and Y are joined so that they remain connected and need never become separated.

"In' the particular form of the invention illustrated the ends of the sections X and Y which occur where" the tab l2 occurs when the blade is in place in the head are notched somewhat, as at 25, to leave the'tab exposed so that it can be readil'y'grasp'ed when it is desired to operate the blade relative to the head. =It is preferred, in

practice, to so'space or locate the lugs 20 and sockets -2| as to make "it impossible to'join the cap sectionto the plate section with the notches 2-5 in other than properly registered relation.

' The stem 0 is preferably asimple elongate part or rod and in practice may vary "in form and proportioning it being preferred, however, .thatit be shaped substantially as shown in the drawings and that it be such as to extend from a point about midway between the ends of the head "B to a' point slightly beyond one end of the head, as'fshown throughout the drawings when the parts are positioned as shown in Fig. 1. The means D pivotally connecting thehead and stem may involve r include any suitable'pivotal connection between these parts. In the 'case illustrated the. connection involves spaced ears projecting from the lower on-bottom: ide of the plate Y about 'midway between the ends of cated by the arrow Z until it reaches a position parallel with the stem C, as shown in Fig. l

fithef head relative to the stem a stop part or 15' projection 33, isiprovided on the end of the stem and cooperatively engages or stops against a stop shoulder 34 provided at the bottom side of the plate Y between the ears 30. It is to be understood that in practice the pivotal connection just described is preferably made snug or tight enough so that the head does not swing freely on the stem but must be deliberately op-' erate'd from one position to the other.

The base E is fixed on or carried by the lower end of stem C and in the case illustrated :it is formed as an integral part of the stem; .In accordance with the present invention the base involves two elements, one a central element or core 35 and the other an outer element or ring 36.

The core 35 is a disc-like part of considerable thickness having a flat outer or lower 'end 31 and a convex or crowned inner end 38. The

lower end of stem C joins the center ofthe' crowned top end of the core so that the stem and coreare concentric.

The 'core 35 has a round periphery 4| concentric with the axis of the core and that of" may be a simple or plain surface, as shown in thedrawings, or it may be ornamented as circumstances require.

In accordance .with the construction provided by the present invention the ring 36 is tight on the core 35, that is the ring and core are made to be snugly or tightly engaged. together, re-

quiring that they ibe pressed together so that these parts are, for all intents and purposes solid or permanentlyjoined- Y In accordance withtheinvention aplurality of .circumferentially spaced and circumferentially extending sockets 50 extend. longitudinally through the base formed by the core 35 and the ring 36, it being preferred-that the sockets occur between the core andthe ring. 1 The desired sockets 50 are established byproviding longitudinal notches in one element or the other of. the base. In thepreferredform v of the invention notches or recesses 5| are provided in the exterior of peripheral surface 4! of the core 35 the notches 50 being circumferentially spaced around the core andbeing such as .to extend from one end to the other of the core.- In the case illustrated three notches 5i are provided and they are of considerable extent'circumferentially as will be seen in Fig. 3 of the drawings. When the ring 36 is applied to orover the core to be tight thereon the notches'5l are covered or closed by the ring with-the result that-the base is established with the desired longitudinala erases 5. passageways orso'ckets' 'therethrough, which sockets areopen. at each endzoflthe' base.

The body F is provided to cooperateswithlthe base E and in...accordance with the preferred form of the invention his a simple element involving an elongate tubular part or Shell and arr end 'l closing-one end-er the Shelli. "The other or opposite end of the shell is "provided with a pluralityof "openings: or; notche 'GZ Which extend-: into the shell-for" a considerable distance and which are cireum-ferentially spaced the shell with the result that a plurality of projections or prongs 63 are established at the end of the shell opposite the closure or end 6|.

The prongs 63 correspond in circumferential extent and in spacing with the sockets 50 in the base. In the case illustrated where there are three sockets 50 in the base there are three notches 62 in the shell 60 establishing three prongs 63. The shell 60 is of such diameter that the prongs 63 on the end of the shell 60 will slidably enter or engage in the sockets 50, and since the sockets 50 are open at each end of the base the prongs may be entered into the sockets from either end.

When the head B is folded to a collapsed position such as is shown in Fig. 1, where it extends parallel with the stem C and is adjacent one side of the stem C, the body F may be engaged over the head and stem so that the prongs 63 enter the sockets 50, in which case the base forms a closure for the open end of the body while the head and stem are encased by or housed in the body. When the razor is to be used the prongs may be engaged in the sockets 50 from the other direction, or from the lower end of the base, so that the body projects from the base forming an effective handle or grip by which the razor may be manipulated.

It will be apparent that the prongs 63 engage in the sockets 50 in such manner as to provide substantial bearing engagement between the body and base, with the result that there is considerable friction between these parts holding them effectively joined in either of the two positions above described. It will be apparent that by slightly deforming the prongs 63 the frictional engagement may be varied so that the desired grip between the base and the body may be established.

It is significant to note that with the construction provided by the present invention there are no delicate or intricate parts involved in effecting the desired connection between the base E and body F and that when the razor is in use with the parts positioned as shown in Fig. 2 the prongs 63 occupy the openings 50, leaving the structure without openings, crevices, or interstices subject to becoming clogged or which may hold foreign matter and thus become unsanitary or disagreeable. Any material that might tend to lodge in the openings 50 is quickly ejected or eliminated by the mere operation of the structure between the positions shown in Figs. 1 and 2 of the drawmgs.

When the razor is folded or collapsed and the body is applied to the base as a cap, as shown in Fig. 1, the entire structure is in a most compact and simple form convenient for storing or handling. When the structure is in use as shown in Fig, 2 the head is supported in a most advantageous manner relative to the handle formed by the body F and the body F presents a part of substantial size conveniently related to the head, making the razor simple and convenient to operate.
