This invention relates to cutlery and more particularly to aV shaving implement or razor of the type disclosed in my co-pending applie-ation iled August 8, 1927,*and having B Serial No. 210,368, now Patent #1,701,036

grantedFeb- 5, 1929. i

One object of this invention is to providev ashaving implement including blade holding and clamping `means in which the 1'0 clampingl means when in an operative position bears against a portion of a blade pro-v j ectingbeyond the blade holdingmeansv andr Causes the blade to'be flexed so that it will cutV very easily when the implement is in use.

Another. object of the invention is Vto provide the razor with means adapted to engage a razor blade and serve not only to properly position the blade upon the blade holder of the razor but also constitute means across 20 which the blade will be bent when the clamping means for the blade is securedin an operat-iveposition.

frnother object of the invention is to vallow hinge members pivotallyV connecting the 255 blade holder with a shank to serve not only as means for pivotally mounting the blade holder but alsov constitute the means for engaging the bladein order to properly position the blade upon the holder and facilitate flexing of the blade. f

Another object of the invention isto provide the razor with a guard for the cuttingedge of the blade adapted to apply pressure w to thek blade when in operative engagement 3 therewith and serve notk only as a guard for the blade but also serving toplace the blade under tension vand preventv danger .of the blade moving when the razor is in use andVV also permitted to cause the blade to move out 40 of its seated position upon the blade.V holder when the blade clamp is released.

Another object of the invention is to allow the blade holder and the clamp and guardV to be moved either together kor independently 4 of each other.

Another object of theinvention is to allow position and thereby insure proper position of the blade holder relative to the handle of the razor when in an operative position. Another object of the invention is to provide the razor with an improved type of handle which is pivotally connected with the shank and adapted to be swung from an eX- tended position for use to a folded position in which the shank together with the elements carried thereby' extends 'through the handle and thereby reduce the razor to a compact mass which can be easily carried.

Another object of theinvention isV to provide improve@L means for pivotally connecting the handle with the shank of the razor and'allow the handle to be latched and there-v by securely but releasably held in either aV folded or extended position.'

The invention is illustrated in the panying drawing, wherein Figure 1 is a view showing the improved f shaving implement in front elevation with the lateh'released and the guard and blade holder swung to a `folded position against the shank, T

Fig. 7Y` is a perspective view of ainodiied form ofguard. i

This improved shaving implement includes i a shank l formedofresilient sheetfmetal and having a wide upper portion or head2 anda 1 reduced lower portion orneck 3. The side` portions of thel head 2 arev split from their 'upper edges to provide tongues which are bent to form hinge ears l and 5 and while the; ears i Aextend forwardly andl theears 5 rear`A wardly in the form illustrated, it will be ob-v vious that the directions in which they extend maybe reversed or the ears may all extend either forwardly or rearwardly if foundV practical. The intermediate portion ofthe head has also been slit from its upper edge t0 .form a tongue 6 constituting a spring, the urpose of which will be hereinafter set forth. It will thus be seen that the shank is formed from a single piece of sheet metal and, therefore, there are no parts to become detached or moved out of their proper positions. Y

The base plate or blade holder'7 against which a blade is to rest is also formed of sheet metal and this plate is formed adjacent its forward edge with openings 8 to receive the hinge ears l and between the openings 8 is formed a raised portion or stud 9 so spaced `from the openings that, when a blade of the Gillette type shown in Figs. 1 and 2 and indicated by the numeral 10 is'placedagainst the base plate, the stud 9 and the hinge ears 4 will be received in openings formed in the blade. This base plate is slit Vfrom its rear edge in spaced relation to its sides, thereby forming tongues which are bent forwardly in overhanging relation to the plate to provide hinge ears 1'1 and between these hinge ears a lip 12 `which is'bent to extend somewhat closer to the upper surface of the base plate than the ears. By this arrangement the lip ll2 will overhang the blade, as shown in Fig. 1, and

y, limitv upward movement of this portion of Ythe blade when pressure is applied to the portion ofthe blade which projects forwardly from the base plate. Y

In order to clamp the blade firmly against the base plate or bladeV holderY 7, there has been provided aclamping frame 13 formed preferably ofstrong wire and having'a cross Vbar 14 from which extend side arms 15.

After forming theside arms, thewire has its end portions benttoward each other to form pintles 16 engaged through the hinge ears 1l to pivotally mount the clamp, andthese pintles are of such length that they overlie the tongue or lip 12. After forming the pintles,

the wire has its end portions bent forwardly,

VVas shownat 17, and terminates in fingers 18 which extend longitudinally of the Vblade holder from the forwardly extending portions orarms 17 and are adapted to rest upon thehinge earsl. The arms 15 are of such i length that they project forwardly beyond the base plate and adjacent theirk forward ends they are bent downwardly slightlylso that whenrthe clamping frame is disposed in its operatiyeposition kthe crossbar '14 will be disposed slightlyy belowthe plane ofthe uppersurface of thebase plate, indicated by the line A-A in Fig. 2,5and when pressure is applied to the clamping frame to forceit toward this position, the pressure exerted by this cross bar against the-portion of the blade projecting forwardly from the base plate, will cause the blade to be Vflexed and assume aV transversely bowed formation which mate-V rially adds to the ease with which the blade cuts when therazor is in use. It should be l.noted that the forwardly extending portions y or arms 17 of the clamping frame arey offset against the upper surface of the blade. This blade is not formed with openings lto receive the lug 9 and hinge ears l but is sufficiently flexible to be flexed across the ears and lug and since the ends of the back 2O fit snugly between the arms 15 ofthe clamping frame and extend between the fingers 18 and hinge earsl 11 with its rear edge contacting with the lip 12, this blade will be firmly held in place and prevented from moving out of its proper position relative to the bladeholder. In order to retain the clamping frame in an operative osition and apply pressure thereto in order tofex the blade, there has been provided a`v clasp 21 formed of strong sheet metal.4 kThis clasp is of a ll-shaped-` formation to provide jaws 22 and is adapted to straddle the blade holder and clamping frame, as shown in Figs. 2 and 3, with one jaw bearing against thel under surface of the base plate and its other jaw bearing upon the arms 17 of the clamp-- ing frame. VTherefore, when the'clasp is in an operative position, it will retain the clamping frame in its operative position shown in Fig. 2 andpressure will be exerted to flex the blade. 1n the preferred formation, the clasp is formed with a side arm 23 through which a rivet Qil or equivalent fastener is passed in order to pivotally connect the clasp with the base plateand thereby Ypermanently attach the clasp to the base plate and prevent it from becoming lost, but it will be obvious that this side arm may beomitted if so desired. Y

rlhe yoke, which is indicated in general by the numeral 25, is alsoV formed of strong wire whichis bent to form a bridge 26 from which extend arms 27, the'free end portions ofthe arms being bent inwardly to form pin- Vtles 28. Intermediate its ends the bridge 26 is'bent to form a bowed portion 29 constitut-z ingarspring element, and this spring ele-V *f ment or arch bears vagainst the'tongue 6 of the shank 1 when the bridge is engaged withY p Y the hinge earsj. By thisy arrangement the yoke will bepivotally mounted and since the f tongue 6 constitutes aspring an .effort must be exerted to swing the yoke either to the po-A sition shown in full lines in Fig... 2 vor thevv folded position indicated by (dotted linesrin this figure and shown in full lines in Figs. 1

and 3. It should also be noted-that.,v when` the yoke is in the extended or operative, posi-f by theaction ofthe tongue 6 and arch 29V Y' tion shown in Fig. 2, it isheld under tension Y and urged upwardly; Therefore, the gua/rd carried by the bridge will bepressed against the cutting edge of the blader transversely thereof and will apply pressure which will hold the extended portion of the blade firmly against the cross bar 142 of the clamping frame and prevent vibration or other movement of the blade when the razoris-in use. It should also be noted that since the yoke has a tendency to move to the position shown in F ig. 5 when extended to' an operative position the pressure upon the blade will serve to cause the blade to be lifted from the base plate and ejected lif the clasp is moved out of engagement with` the clamping frame when the elements of the razor are in the operative position shown in F ig. 2. guard may be in the form of a roller which is rotatably supported bythe pintles 28 and in the preferred form the roller is provided with ribs 3l which extend. spirally about the roller and by their engagement with the cutting edge of the blade will serve to remove hair from the cutting edge of the blade during a shaving operation and will also serve to maintain a sharp edge upon the blade.

' l/Vashers 32are providedat the ends of the roller in order to preventit from slidingl longitudinally upon the pintles 28 and thereby retain it in its proper position relative to the cutting edge of the blade. These washers may be iixed to the ends of the roller or they may be separate from the roller and either loosely applied upon the pintles or fixed to the pintles. instead of using a roller for a guard, it is sometimes preferable to a non-rotary guard, such as shown in Fig. 7 and indicated by the numeral 33. This guard' is preferably used when the razor is employed toy trim a persons hair and may be formed with either fine or coarse teeth lill. or itmay have coarse teetn upon one side and fine teeth upon an oppositeV side.V `The end portions of the guard are formed with sockets 35 to receive the pintlesl .28 and in addition has its end portions'foimed with transversely extending grooves constituting seats toV Vreceive the outer end portions ofthe arms 27 of the oke. it willt'hus'be seen that Vwhen this form of guard is in use,it will be held against rotation but it will bear against the cutting edge of the blader similar to the manner in which the roller bears against theA p blade. It will also be obvious that the roller may be formed without the spiral ribs yor it may consist of a strand of wirebentto'fori'n spirals corresponding to the ribs and having eyes at its ends to receive the pintles..l

The handle, which is indicated in general by the numeral 37, is formed vof resilient metal and consists of a strip bent intermediate its length to form an open handle having spaced' arms 38 and, 39Y yieldably connected by a bridge 40 'which imparts resiliency tothe handle anda allowsitsy arms to have movement toward and-:awayfromeach other. The lower end or neclri ofthefshank l is receivedabetweenthe freeendsiA ofthe arms 38 and 39y and. from theneck extends a pin or stud 40, to loe-.received in. an openingl l1 formed inthe arm 39: 'llhisfpin may loeV headed similar to a rivet to; permanentlyY connect the handlewith the'shank, but-in the preferred formationthe pin .is'left unheaded thereby allowing the handle to. be detached from the ,shank in order tov allow the razor to bethoroughly cleaned; or allow. ahandle to be removed when a razor Vis`sold` and ahandle'of different value or type toi'be` substituted for one alreadyin place'.4 Lipsoi: flanges 42' extend from oppositesides ofthe free end'portion of thea-rm 38'. Theseflanges extend from the arm, asl shown in Eig.l 4, so that they mayy engage opposite side edges of the neck 3 and thereby constitute stops which prevent the handle from easily turning relative to the shank. Itshouldibe noted', however, that at their inner endsthe flanges slope toward the arm 38 andV form camzsurfaces which allow the handle to be swung from the extended orA operative; position. shown in Figs. l and 2 to a folded position, as shown in F ig. 3. When inthe folded po.- sition, the handle will bereleasably securedi by the flanges which serve as latches andi the handle will be disposed about the shank and elements carried thereby. Therefore, thier razor will be reduced toa compact mass which can be placed ina small case and easily carried in a persons pocket'without dangerV of a person cutting'his hands if a. case-is omitted. When the razor isy in use, the handle moved to its extended position and the blade Y holder swung to the operative position shown in Fig. 2. The clip or Clasp 21 is moved out. of engagement with the clamping frame so that this frame may be swung upwardly and the blade is set in place upon the base plate.. After the blade has been set in place, the! clamping frame Vis again swung downwardly into positi'on'to bearagainstY the portion of` rio the blade ro'ectinfr forwar l from thefbase'. P l s Y las f edge of the blade and in additionrcausefthe 'i blade to be honed andtherebykept. very sharp.' Ifhair collects betweenthe roller and the blade, the,v yoke may be. sawing'downs` wardly and the soap and haireasily washed from the blade and roller or if a person Vis using the razor to trim his hair without the use of soap, it is merely necessary to swing the Y ly to the position shown in Fig. 5 and this will cause theV clamping frame to be swung upwardly, as shown in this ligure, and cause the blade to be released from the base plate and propelled forwardly. The razor and blade can then be thoroughly cleaned and after being dried reassembled. When the blade is again in place,the yoke is swung downwardly against the shank and the blade holder swung to the foldedposition shown in Fig. l, after which the handle can be swung to its folded position in which it extends in encirclingl relation to the shank and elements carried thereby, as shown in Fig. vVhen so` fold-ed,

Vit will be reduced to a very compact mass and it may be stored in a small space or carried vin a personshand or pocket without danger of a person being cut by Contact with the sharpened edge ofthe blade.
