, razor so constructed that its parts may be i so ' razor embodyin the invention.

dis-assembled and folded into compact form. Other objects of the invention, not at this time more particularly mentioned will be fully understood from the following detailed description'of the invention.

The invention consists of the improvements hereinafter described and finally claimed.

The nature, characteristic features and scope of the invention will be more fully unclerstood from the following description taken inconnection with the accompanying drawings forming art hereof, and of which Figure '1, is an e evational View 0% a safety i 2, is a similar view ilTustrating certain parts detached Fig. 3, is a sectional view of the upper. part of-the razor, drawn to an enlarg'ed scale, and taken at right an les to Fig. 1. Fig. 4, is a sectional view ta en on the line 4-4 of Fig. 3. Fig. 5, is an elevational view of Fig.3, and illustrating the.

position; of the lock-nut prior to dis-assemling the parts of the razor. Fig. 6, is an elevational view illustrating a slightly modified form of the invention. Fig. 7, is a simi lar view illustrating certain of the parts detached and also showing the hin ed relation of certain of the parts. 3 Fig. 8, illustrates in elevation and section a still further modified *form of the invention and wherein certain of the parts are adapted to be carried within the ho low handle of the razor, and Figs. 9 and 10, are views illustrating a blade and 4 blade holder used in connection with'the razor shown in Fig. 8.

Referring to the drawings, there is shown a straight tubular handle 1, whichmay have its outer surface roughened. to enable it' to be securely gripped when inuse. Risin from the handle 1, is a stem 2, of slightly smaller diameter than the handle. Carried by the stem 2, is a backing plate 3, com-avoconvex in cross section and having formed upon its side edges tooth-like projections 4, the said plate being preferably formed integral with the stem 2. The backing plate is provided centrally thereof with a slot 5,

' .which communicates with a slot 6, in the stem 2. This backing plate is also provided with perforations 8. There is also provided a removable flexible razor blade 7, provided with perforations 0 and a centrally arranged slot 10.

Surmounting the backing plate and razor blade is an operating plate 11, also concavoconvex in cross sectionand being provided with studs 12, and a centrally arranged threaded extension 13. As shown, this threaded extension 13, is provided with flat sides 14, and the threaded portions are arranged upon what may be termed ts respective ends. This threaded extension is adapt-.

ed to penetrate the central openings in the razor blade and backing plate and is extended within the slotted stem 2, as illustrated. In this connection, it may be remarked that the threaded ends project slightly beyond the Walls of the slotted stem 2, and are adapted to engage with and be locked to place by a lock-nut 14. This lock-'nut 14, is shown as being free to move vertically with respect to the stem 2, and its downward movmnent is limited by the shoulder 15, formed by the upper part of the handle 1. To assemble the razor parts, the razor blade is'placcd upon the backing )late and the openings and slot. therein are a ined with the openings and slot in said backing plate. Theoporating plate with its studs and threaded extension is then placed in position, the said studs passing throu h the openings in the blade and backing p ate and the threaded extension of the operating plate passing through the slot in the blade and backing late and passing down Within the slotted portion of the stem 2, of the handle 1. The lock-nut is then pushed upward to engage the threaded ex--- tension and by turning said locknut from left to right, the operating plate is drawn downward, and the razorblade flexed so as to cause its cutting edges to approach the tooth-like projections 4. By turning the lock-nut from right to left, the razor blade is permitted to assert itself and pushes the operating plate u ward and away from the backing plate, an as the thing is done, the blade assumes its normal or fiat shape and the lock- ,5 struction t 85 parts are 45 space.

mg a comparatively thin metallic case cen 50 to penetrate the slotted blade and by sli when the razor 'is not in use. As s own in the vdraigvingathe stem a, may comprise a tubular member rovided with a flattened extension b. The acking plate 4, carries the bifurcated member 0, which straddles the ex-- tension 1), and is pivoted thereto'by means of a pivot d. The tubular extension and the lower )ortion of the bifurcated extension 0, are 1110 med with respect to each other as at 0 so that the pivoted backing plate may only turn in onedirection when it is desired to bring it from a horizontal to a vertical 1 position, the object of which, of c( )urse ,-is t0 make the razor parts firm with respect to the I handle when in operative position. The operatlon of this device, will be understood in connection with the foregoing description without further comment.

Referring now to Figs. 8 to 10, inclusive,

the razor parts are shown as being carried by "a tubular hollow handle E, provided with a screw. threaded interior art F, adapted to receive a similarly threa ed cap G. H is a cap adapted to be fitted to the handle E. As shown in the drawings, the razor similar to those described with reference to Figs. 6 and 7, and it will be understood that by swinging the backing plate together with the blade and operating plate from a horizontal to a vertical osition,

as shown in Fig. 8, the cap H, may e fitted to lace. The case I may be readily placed wit 'nthe handle E, and the cap G, screwedto place and such a razor obviously presents a neat a pearance and occupies but little he blade case is shown as compristrally perforated for the reception of a spring controlled catch J. 'This catch is provided with a flattened spear-like head K, adaplteid t Y turning said catch cause the flattened ead to extend across the slotted portion of the jection whereb blade and securely hold the same to place.

Obviously the lock-nut holds the positiomng late and blade firm with respect to the andle. The cap H may be fitted over the part L, as shown in dotted lines when using the razor.

What I claim is: 1. A safety razor comprising a tubularhandle, a smaller stein carried by'the handle and having formed integral therewith a backingplate, said plate and stem being centrally I slotted, a centrally slotted blade, an operating plate for co-action with the backing plate, said operating plate being provided with a centrally arranged and threaded projection for penetratmg the aforesaid slotted parts, A

and a lock-nut for engaging the threaded prothe operating late. is drawn toward the bac ing plate to ho d and flex the blade.

2. A safety razor comprising a handle having a stem, a slotted backing (plate provide}? with a bifurcated member sa1 iigfpivotal relation with said stem, a slotted a the backing plate said operating plate bei provided with a centrally 'arra ed an threaded extension for penetrating t e aforesaid slotted parts, and a lock-nut for engaging the threaded projection whereby the operating plate 1s drawn toward the backing p ate to hold and flex the blade.

3. A safety razor comprising a hollow handle screw threaded at its lower end for the reception of a screw-threaded cape. top cap, a stem superposed upon the han e, a backing plate provided with a bifurcated extension said extension having pivotal relation with the stem, a blade, an operating plate having a threaded extension for blade, backing sion, and a loc 'ng-nut for threaded extension whereb member hav}.

e, an operating plate for co-action withpenetrating the. A late and b furcated,exte'n'-- engaging the the operatingplate is drawn toward the acki'ng plate toold and flex the blade.

In testimony whereof I have hereunto signed my name in the presence. of witnesses. LEON EBNER. Witnesses: I I
