[The present invention relates generallyi to shavingimplernents.and reiers particularly to safety razors of the dry shaver type;

An object oi' the invention is the provision of a razor having one or more movable cutters` in association with one or more comb plate sections capable `of being pressed'down uponthe cutters to effect the cutting or shavingperation.

v A.further object `is to provide a cover guard for the shavinghead formed of ajleXibleand,

pliable rubber-like material., adapted, to envelope the head and which is of slightly smaller size than the head so that it will be stretched VoverV the same vand thereby exert an over-all .con-y strictive force upon the head which Vcauses vthe comb plate sectionsto be pressed atall cutting points against the movable cutters. It is `to be understood that openings are provided in .the

cover. guard to expose the shaving surfaces of the shaving-head. c in this connection the comb plate sections are. either detachably mounted in the shaving head or so associated therewith yas to permit said sections to be readily pressed down upon the cutter bythe cover guard. Furthermore, the-cover guard-protects the shaving head from damage, absorbs vibration and protects the face of thev person being shaved.

A further object is the provisionfof a cover guard having areas in advance 'and' in rear of the Ashaving surface, the first of which tends to tauten the skin and the-'other of which tends tof raise and straighten the whiskers lintoa position tobecut at the next shaving stroke.

Another object is to provide a razor having a.

pair of rotary cutters moving` in opposite directions, thus making it possible to out with the grain ofthe whiskers at one stroke and against the grain at the next stroke.

A still further object is the provisionof a razor havingauxiliary shaving surfaces .on thev ends ofthe shaving head.

`Another object .is to provide a rrazor `having.

oppositely facing comb plates f or sections which form .angular-openings or slotsbetween oppositely facing and overlapping teeth and means for separating the platesections to increase the size of the angular slots. f

A further object is the vprovision of a ,shavin implement having a suction fan associated Arvvith. the cutters so as to drawthe cut Whiskersaway..

Fig. 22 is-a perspective view of one of the spacers.

Referring now to the drawings the numeral I8 designates generally the razor forming the subject matter of the present invention. This razor is provided with an elongated casing I I having a shaving head I2 at one end thereof, and an eX- haust fan I3 mounted in the casing lI below the shaving head and having a discharge opening I4.

Referring to Figures l to 4 it will be observed that the shaving head I2 is of substantially cylindrical form and is provided with curved wall portions I5 and I6 preferably forming an integral portion of the casing II. Referring particularly to Figure 4 the wall portions I5 and I 5 are spaced from each other at their lower ends to form a passage I1 communicating with the fan I3. Wall portions I5 and I6 are connected at their opposite ends by means of a pair of end frame sections I8 (see Figure 5). These frame sections I 8 are preferably formed integrally with the wall portions I5 and I6 although, if desired, they may abut these portions and form a continuation of the side walls I9 of the casing II. It will be observed that the walls l5 and I6 terminate at about the center portion of the shaving head and form a substantially semicylindrical frame for receiving a pair of rotary helical or spiral cutters 28 and 2 I. Extending upwardly and around the cutters and cooperating with the wall sections I5 and I6 to complete the shaving head, is a comb plate 22 consisting of a pair of comb plate sec-A tions 23 and 24.

Referring to Figures 2, 3 and 17, it will be observed that the convolutions 25 of the cutter 28 extend in the same direction as the convolutions 26 of cutter 2I. However, these cutters are rotated in opposite directions, thus making it possible to cut with the grain of the whiskers at one stroke and against the grain at the next stroke.

The means for supporting and rotating these cutters will now be described in detail. Referring particularly to Figures 2,'3 and 17 it will be observed that the convolutions 25 of the cutter 28 are positioned between an inner ring 21 and an outer ring 28. This is also true of cutter 2I which is provided with an inner ring 29 and an outer ring 38 embracing the convolutions 26. Each inner ring 21 and 29 is provided with a set of notches 3|, these notches being diametrically opposed and in alignment. A pair of inner plates or disks 32 and 33 respectively, are each provided with a set, of outwardly projecting lugs 34 which are received within the notches 3 I. At the outer ends of the shaving head are located additional disks or plates 35 and 36 respectively. Each of these disks is provided with a set of four evenly spaced lugs 31 which t into cooperating notches 38 'formed in the outer rings 28 and 30 of the cutters 28 and 2 I. In addition to the notches 38, each of the rings 28 and 38 are provided with a plurality of cutter ngers 39 which project outwardly from and lengthwise of the cutters for a purpose to be hereinafter described.

All four of the disks 32, 33, 35 and 35 are loosely mounted upon a shaft 48 extending axially of the shaving head. That' is, the disks are not fixed to the shaft lbut are capable of being rotated thereon. It will be observed that the inner disks 32 and 33 are of dish-shaped formation and are provided with centrally disposed openings for receiving the shaft 48. A plurality of inwardly extending pins 4I are formed on these inner disks andV project into openings formed in bevel gears 42 and 43 (seeFigure 3). These gears mesh with a third bevel gear 44 fixedto the upper' end of a shaft 45 mounted in and longitudinally of the casing Il. Rotation of the shaft 45 and gear 44 in the direction of the arrow imparts rotation to the gear 42, disk 32 and cutter 28 in one direction and at the same time rotate the gear 43, disk 33 and cutter 2| in the opposite direction (see arrows on cutters).

The outer ends of the shaft are provided with reduced portions 4S, each of which is received within and rests upon the inner end of an open ended slot 41 formed in one of the end frame sections I8 (see Figures 3 and 5). In order to retain the shaft in operative position against longitudinal movement, it is provided at each end exteriorly of the reduced portion with an enlarged ball-like end portion 48. Each end portion projects outwardly from its respective frame section I8. Sets of ball thrust bearings 49 are positioned' at theopposite ends of the shaving head between the dished portions of the disks 35 and 36 and their respective end wall section I8 to facilitate rotation ofthese disks and the cutters 28 and 2I. A pair of end plates 58 are mounted on the ends of the shaft 48. Each plate (see Figure 6) consists of a disk-like portion 5I' having a centrally disposed opening 52 which receives one of the heads 48 of the shaft. Each disk portion is provided with a plurality of inwardly extending 301" pins 53 which pass through openings 54 in one of the end frame sections I8. A pair of spaced fingers 55 project inwardly from the peripheral edges of each disk 5I and engage over their respective end portions of the comb plate sections 23 and 24. In order that the lingers 55 will exert an inward pressure upon the comb plate sections, a spring 56 is secured in a slot 51 formed in each of the disks 5 I. As shown in Figure 6 each spring is provided with a central bowed portion 58 which bears against the reduced portion 46 of the shaft and tends to press the disk downwardly and thus cause the ngers 55 to exert pressure on the comb plate sections.

In order to detachably retain all of these parts in operative position, a pair of end caps 59 are provided. These caps have an outer curved portion 68 and a plurality of inwardly extending spring ngers or clips 6I. As shown in Figure 8, the inner ends of these lingers forma centrally disposed opening 52 which receives one of the heads 48 of the shaft 48. These caps 58 may be easily attached to the ends of the shaft by snapping the clips over the head 48of its respective end of the shaft.

y plates 58.

With a construction of this character it will be observed that if desired or necessary the shaving head may be easily and quickly dismounted by first removing the end caps 59 and the end The 'comb plate sections 23 and 24 are next removed and the shaft 48 may then be lifted out of the slots 41 in the end frame sections I8. Thereafter, the disks and the cutters may be removed from the shaft 48.

Referring to Figures 13 and 15 it will be observed that the comb plate sections 23 and 24 together form substantially a semi-cylindrical construction which engages the top longitudinal portions of the wall I5 and I 6 whereby the rotary cutters 28 and 2| areenclosed within the shaving head.

Referring to Figures 18 and 12 it will further be observed that the comb plate sections have their inner sides of a shape to Iconform to the` periphery of the rotary cutters, while the thickness .of each section decreases from its outer Sie edge4r portions towarda center linef along the" top ofthe shaving head. Thus the thinnest parts of the .combplatesectionsare along this center line.- The .comb plate'sections have what may be considered'auxiliar-y slots- 63 thatserve to increase the shaving area and which extend transverselyvo'f the comb plate -sections in parallelrelation. These slots lare offsuitable size to accommodate all sizesI ofhuman whiskers in the thicker parts-of theplatesections.

Referringparticularly to Figures 13 and 15, it will be observed that the center line edge portions of said plates are formed with a plurality of projecting teeth 6l!` except at the outer end portions 65and the middle portion 66, which are straight. The teeth of comb plate section 23 are positioned in staggered relation to the teeth of the plateV 24: Therefore, when the plate sections are brought together as shown in Figure 13, the 'teethof one section-ntintoithe spaces between the teeth of the other section. This provides a comb cutting blade arrangement wherein the-"adjacentJ teeth ofopposite sections are arranged in overlapping relation. The construction is such that whenthe straight end edge portions65 and the centrally disposed straight edge portions Bit-abut, there is a clearance between the overlapping teeth 64 which provide angularly disposed slots.

One set-of these slotsBl will be inclined in. one direction while the other set rof slots 68 will be inclined in the reversed direction. Furthermore, both sets of slots will communicate with straight slots 69 formed in the plate sections between the teeth and also between adjacent slots 63.

*The'angular' slots G1 and 68 are located within the thinnest zone of the comb plate sections and arepreferably of a smaller size than themain slots 63 so as to prevent the skin of the shaver fromv squeezing through to the cutting surface of the rotary cutter. The size of the angular slots 61 and 6,8 is governed by the distance between the .adjacent edge portions 65 and 66. The width of these angular slots may be regulated or ad- `iusted by having different size spacers or separators 65' placed between the plates or the distance may be predetermined. by.A having an extending edge of, one plate bear against the edge of the other. The thinness. of the comb plate section in the zone of the angular slots permits closer shavingat that point but .with safety because of the smaller openings ofthe slots. The main slots accommodate whiskers of greater diameter because of theirr wider openings and with safety sincethe skin, surface is held further away from the rotary ycutters by the thickened part ofthe combplate sections. In a stroke of the razor over the skin surfacethe whiskers are cut progressively shorter as it' passesfrom thick to 'thin zone whichof course is a desirable feature leading to a. close shave.

Since the angular slots 51 and 68 communicate with the slots 59. there is a tendency to comb, straighten and guide the whiskers into these latter-slots. Furthermore. the-closedopposite ends of thev slots 59 ,act as claws or obsta cles to catch andforce flatl-lying whiskers into the'slots. By

having thecomb plate sections thick at one end. there is given an added -structural strength to theY plate sections. Furthermore. since the points of the teeth Moi. one plate section extend across the center line and into the vthicker zone of the opposite plate section when thesections are brought together asshown in Figures 12 and 13, these points are prevented from gouging into the flesh.

is'd'ue to the fact that' the outer surfaces of l circumferentially from .points adjacent thejinnenv closed ends of the slots 63 and toWards the ends of.

theteeth' (iL-(Fig. 12)'. This arrangement pro.-

vides means for bringingy the skin/closer. tothe;

moving cutter in the areaofrtheteeth. 64with out danger ofv injuring or burning the skin. Moreover, the selective adjustment of the'slotslfli and t8 allows these slots to be narrowed so as to insurea smooth, clean shave. The thickness ofs'a.. human hair is approximately .008 of an inch and the slots 6l ancl68 in .the shaving head should not i he much wider since if they .are the skinwill squeeze through them. have extreme thinness in the metal from whichv the shaving head is stamped so as to insure;a..

closel shave, i. e., this metal should be about .092 of 'an inch adjacent the close-shaving area. Such accuracy in constructingthe shaving head calls for precision die work with very little tolerance allowedto the die maker. In the presenti invention the shaving head has the tranverse slots 69 -of about 1/64 or .015 of an inch in Width which is about the size of slots in shaving heads now on the market. While a portion of the slots yt9 are located in the thicker part ofthe sections arrangement provides means for bringing the` skin closer to the moving cutter, and avoids injuring or burning the skin. Heretofore, to make slots of less than 1/'64 inch presented a dimcult problem which is simply solved by the present construction, sinceby bringing the oppositely facing sections 23 and 24 toward each other with the teeth 64 ojf one section ttingvinto the spacesbetween the teeth of the other, the slots 6l and 68 may be narrowed to insure maximum= efficiency of the shaving implement.

' As lstated at the outset by having thel cutters Eiland 2l rotate in opposite directionsit -is possible to out with` the grain ofthe whiskers at one stroke vand against the grain at the next stroke.

In order to insure an ef'cient shavingl op-Y eration means are provided to exert an overfA all constrictive forcev upon the shavingheadsoas to cause the comb plates to be pressedat all` ures lland 4' this guard is providedwith a longitudinally extending openingl ll, the .edgesof which engage the restricted portion l1. of", the casingwherev it joins Ythe. wallportions ISQ-and lof the shaving-head. Furthermore, openings 1 'l2'and V 13 are provided'inthe cover guard to exf-l pose the main shaving surfaces. End openings'. T4" are also provided in lthe cover guardv to exe, pose auxiliary cutting surfaces which lwill ,betex plained in detail hereinafter.`

In addition. to exerting an overall constrictive. force upontheshaving head, the. cover, guard alsoprotects the head from, damage, absorbs.; vibration and also protects the facevof the per- It is also necessary to..`

son being shaved. Furthermore, that part of the cover guard which advances ahead of the shaving surface clings to and tautens the skin just as the running of the ngers ahead of a razor blade does in the old style type of shaving. That part of the cover guard which follows behind the shaving surface'tends to raise yand straighten the whiskers into a position to be cut at the next shaving stroke.

To facilitate the cutting of the hair around theears and nostrils and in case of a moustache, there is provided a clipper at each end of the shaving head. Referring particularly to Figures 2, 3 and 4, 13 and 14 it will be observed that the outer rings 28 and 39 of each of the cutters are provided with the plurality of outwardly projecting ngers 39 as herein before described. Certain of these fingers are also formed by reason of the slots 38 which receive the lugs 31. Associated with the ngers 39 are a plurality of teeth 'I1 formed on the opposite ends of the comb plate sections 23 and 24. When theseV plate sections are in operative position the teeth Il will overlie the ngers 33. As the ngers 39 are integral with the cutters and since the cover guard 'Hl and the iingers 55 of the end plates 5l! press the teeth 'il inwardly into engagement withthe cut-ting edges of the fingers 39, a cutting action is provided at each of the clippers l5.

For the purpose of keeping the razor and particularly the shaving head in a clean condition and to prevent clogging of the cut whiskers in the head the centrifugal type exhaust fan I3 is provided. As shown in Figures and 21 this fan is mounted in a chamber 'I8 and iixed to the shaft 45 Iwhich rotates the bevel gear 44. The curved side wall 'i8' of chamber 4i8 is of volute conguration andwforms with the peripheral portion of the fan I3 an air discharge channel 19 of gradually increasing width. It will be observed that the inner end 80 of the 4side wall 18' of the chamber is spaced from the outer end 8| of the side wall to form therewith the discharge opening I4. The chamber is provided with an inlet opening 82 (see Figures 2 and 3) into which air is drawn from the shaving head. It will be observed that the disks 32, 33, 35 and 36 not only constitute a supporting means for the rotary cutters 2li and 2l but also prevent the cut whiskers from coming into contact with the gears 42, 43 and 44 and the thrust bearings 49. In other words, these parts are protected by the disks and the cut whiskers are drawn past the same into the casing and discharged through the opening 82. I have found from actual experience that efficient operation is obtained by reason of the centrifugal type fan and the volute air discharge passage.

The shaft 45 extends through the fan chamber 18 and is adapted to be rotated by any desired power means such as an electric motor (not shown) which may be mounted in the casing below the fan. A conductor cord 83 is adapted to connect the source of power to the usual electric outlet.

It is to be understood that the invention is not limited to the details of construction shown in the drawings and that the phraseology employed in the specification is for the purpose of description and not of limitation.
