App1ication'flled August 18, 1919.; Serial No. 31am.-

To all whom it may concern.-

Be it known that I EowiN .L. PAon, a

tates and a resident Mono,- and State,

of Bridgeport, county of of-California, have invented a new and useful Safe y-Razor, of ,which the 'follow1ng is a specification.

My'invention relates to safety razors and partlcularly to the typehaving a thin double ed ed reversible blade. .n object of the inventlon is to provide a safety razor in which the razor. blade guard is disposed on the blade upon the side opposite to that on which the cut hair and'lather collect during the shaving operation. In

this manner the guard, does not interfere with the cutting of the hair and permits a free movement of the latherand cut hair duringthe operation of the razor.

Another object of the invention is to provide a safety razor inwhich the razor blade guard maintains a fixed cooperative relation with respect to the cuttlng edges, ,regardless of the varlation in the width of the blade;caused by the continual re-sharpening of the ed es-thereof.

A further obgect, of the invention is-to provide a handle for a razor having a double edged blade, whose'positionmay e readily changed, in order that the blade may be held at the proper cutting angle regardless of the particular cutting ed e that 1s used. The invention possesses ot er objects and features of advanta e, some-of whlch, with the foregoing, will e setforthfin the following description .of the preferredwforms of myinvention which is illustrated in the drawmgs accompanying and forming part of the specification It is to be understood that I do not limit myself to the showing made by the said drawings and description,

' as I may-adopt variations of the preferred forms within the scope of set forth in the claims.

Referring to said drawings:

'Flg. 8 is across sectional view similar to F 1 g. 7-, with the exceptionthat the supporting member is included and theguards are .shown in their operative position with respect to the cutting edges of the blade.

Fig. 9. is a cross sectional View similar to Fig. 7, of a-slightly modified 'form 'of the razor.

Fig. 10 is a vertical cross sectional view showlng my invention as applied to a razor havlng a single cutting edge. The guard is shown disengaged" from the cutting edge of the blade.

Fig. 11 is a. vertical cross sectional view cooperative relation with the cuttlngedge of the blade.

Briefly'state'd my invention comprises a set-of guards which are disposed on the clean side of the blade, each guard being arranged to cooperate independently with the cuttingedge with which it is: associated. Means are provided for normally holding the, guards out of cooperative eng ment with the cutting edges so that the bla e maybe initially positioned on the razor. Means are also provided for causing theguardsto cooperatively engage the cutting edges in ess of a fixed or unvarymg relation regard variations that may occur in the width of the blade. Means are also included -'for enabling the blade-to be readily held at the proper .cutting 'angle regardless which cuttin edge it .is deslred to use.

' detailed description of my invention follows The safety razor of m invention, in broad terms,-isofthe type w ich employs a double-edged blade of such thinness that external support isrequiredto give rigidity to its cuttin edges. Safety razors of this type are usua ly provided with a razor blade guard which is' arranged on the blade upon the side on which the cut hair and lather collects. This construction in many instances-prevents the free movement of the lather and cut hair and'more or less impairs the smooth shaving qualities of the razor. In accordance with my invention the guards are disposed on the blade upon the side which faces the roots or'the hair when the razor is shaving the beard. In this manner the guards do not interfere with the cuttingo eration of the hair orimpede its passage a r it is cut.

In'the present form the cutting edges 3 and 4 of the blade 5 are provided .with thin straight edged

guards

6 and 7 respectively,

arranged to engagethecutting edges 3 and 4 when the razor is assembled.

l guards. Formed on the integral studs 12 which are adapted to ent 1 Means are provided for holding the ards'extended with relation to each other in order that the blade may be placed between the two pairs of projections 9 on the ard '6 is a set of gage alined, perforations or slots 13 provided I videdon the guard 7 the studs being so po- .sitioned onthe guard that they lie in proximity to the studs 12 of the guard 6 when the studs 12 extend through the perforations 13. The studs 12 are provided with springs 15 which are arranged to ress against'the studsl to hold the guar s in Y extended'relation. The -blade,iwhich is suitably slotted to clearthe studs, may then. be inserted between the guard projections. Means are also; rovided for moving the guards inwardly a ter the blade has been insorted between the projections, in order that the's'aidprojections, may enga e the blade andhold the guards in fixed re ation to the cutting edges, regardless of an variation i that may occur in the width 0 the blade.

Arranged to lie on the reverse side of the blade is a supporting member 17 which is provided with means for efi'ecting engagement of the projections and blade. Secured to the studs 14:. and disposed on the side f thereof opposite to that against which the r consi erably less resiliencethan the springs sprin 15 presses, are springs 18 having 15. The supporting member is provided with slots 19. which are adapted to engage the springs 18 and the studs 12 to cause the projections to be drawn toward each other to yieldingly engage the blade and hold the guards in proper relati to the cutting edges. It willbe noted t at the guard pro jections are arranged to engage the cutting edges of the blade. and since the projections are fixed tothe guard, the same relation must always exist between the guardand its associated cutting edge whenever the projections properly engage the cutting edges. 7 Asmay be seen by referring to Fig.

theguard 7. A set of studs 14 is also pro-i stud 21 which is arranged to pass through

suitable apertures

22, 23 and 24 provided in the guard v.7 ,blade 5, and supporting member 17 respectively. A handle 25, screw threaded internally, is arranged to engage the portion of the studwhich projects beyond the supporting plate, to clamp the blade between the supporting plate and guards. The body of the handle is bent to enable the razors to be readily held at the propercutting angle and the head of the handle is provided with a spring pressed cap 27 which is adapted to press against the supporting member and thereby provide a yielding engagement between the handle and supporting member. This construction permits the handle to be turned to enable the razor to be held at the proper cutting angle for either edge without affecting the clamping of the razor.

In the drawings all of the figures with I exception of Fig. 1 show the parts inverted since these figures represent the razor not fully assembled and it is in' this inverted position that the razor is preferably assembled. In assembling the razor the first step consists in' placing the guard 7 upon the guard 6." The blade is next placed in position and isfollowed by the supporting member. The handle is then added to clamp the parts together.

In disassembling the razor the assembling steps are substantially reversed.

In 9, I have shown a slightly modified construction. In this form the ends of the

springs

15 and 18 are extended and engage in suitable recesses 29 and apertures 31 respectively. This prevents .the springs from being bent out of proper position when handled roughly.

In Figs. 10 and 11, I have shown my inv'entionas applied to a razorhaving a single cutting edge. The construction of this form of the invention is quite similar to that of the double edge type, with the main exception that a backing 33 is substituted for the guard 6. In this embodiment the studs 12 are formed with integral tapering wings 34. These wings may be substituted .for. the s rings 15 in either form of the invention.

en the guard 7 is being placed on the backing 33, the apertures 13 of'the guard 7' engage the sloping sides of the wings and cause the guard to gradually move outwardly thereby enabling the blade to be placed in the proper position preparatory to its engagement with the guard projections.

I claim:

1. In a razor, the combination with a perforated blade having two opposite cutting edges, of an independent guard for each cutting edge, arranged on one side of said blade, means on said guards arranged to extend through the erforation in the blade for holding the guar s out of operative relation with respect to said cutting edges, and a supporting and guard adjusting member dis posed on the other side of said blade.

2. In a razor, the combination with a perforated blade having two opposite cutting edges, of an independent guard for each cuttingedge, projections on said guards for engaging the cutting edges adjacent the ends thereof, means on said guards arranged to extend through the perforations in said blade for normally holding said projections spaced outwardly from said edges and a supporting member arranged to move the said projections inwardly to resiliently engage the blade edges.

3. In a razor, the combination with a blade having a cutting edge, of a guard coeperating with said edge, a supporting member adapted to engage said blade, and means operatlve by the movement of said member in a plane substantially perpendicular to that of the blade for moving said guard in a pllaiiie substantially parallel to that of said 4:. In a razor, the combination with a blade having a cutting edge, of a guard coeperating w1th said ed e, means on said guard for engaging said e ge, a supporting member adapted to support said blade, and means operative by the movement of said member in a plane substantially perpendicular to that of the blade for pressing said edge =engaging means inwardly to resiliently engage said cutting edge.

5. In a razor, the combination with a perforated blade having a cutting edge, of a guard for said edge, projections on said guard for engaging the end portions of said edge, means coeperating with said guard passing through the perforations in said blade for normally holding said projections spaced outwardly from said edge, a perforated supporting member .coeperating with said guard and arranged to move said projections inwardly to resiliently engage the blade edge, clamping means passing through the perforations in said blade and supporting member, and a handle engaging said clamping means and disposed on said supporting member.

rated guard and extend the guards with respect to each other, studs on said perforated guard, springs on said studs of lesser resiliency than said: first springs, a erforated supporting member through whlch all of said springs and studs, extend and adapted to press against the studs of said first guard and the springs of said perforated guard, means for detachably clamping the blade between said guards and supporting member, and a handle disposed on said supporting plate.

7. In a razor, the combination with a thin perforated blade having two op osite cutting edges, of a guard for one 0 said cutting edges, studs springing from said guard and provided with a resilient portion, a perforated guard for the other cutting edge, and arranged with said first guard on one side of the blade, said studs being arranged to pass through the perforated guard' and extend the guards with relation to each other, projections on said guards for engaging the edges of the blade, said projections being disengaged from said edges while the guards are in said extended position, studs springing from said perforated guard and provided with a resilient portion, said portion having less resiliency than the resilient portion of said first named studs, and a perforated supporting member disposed on the free side of said blade and arranged to engage the studs of said first guard and the resilient portions of said perforated guard to move the guards toward each other and thereby cause the projections on the guards to resiliently engage the blade edges.
