United States Patent SHAVER WITH HAIR RAISING BRUSH John T. Scully, New York, N. Y.

Application May 26, 1950, Serial N 0. 164,316

16 Claims. (CI. 30-34) My invention relates to shavers, hair cutting machines in which relatively movable members cooperate to shear or clip oif hairs, such machines being sometimes referred to as hair clippers, dry shavers, shaving machines and the like and are employed without the use of shaving cream, soap lather or other beard emollients.

Reference is made to my co-pending applications for improvements in shavers (titles changed to: Brush Attachments for Shavers), Serial No. 120,783, filed October 11, 1949, and Serial No. 132,547, filed December 12, 1949.

Among the objects of the present invention are the provision of an improved combination of facilities for dry shaving, the provision of a compact and efiicient arrangement of a hair up-raising brush and a shearing head or heads, the provision of an improved hair up-raising brush for cooperative action with the shearing head or heads in the shaving operation, the provision of improved seating means for the brush adjacent the seat for the shearing head or heads, the provision of improved and compact means mounting a hair up-raising brush movable towards or away from a shearing head, the provision of means for spacing a hair up-raising brush adjustably from a shearing head, the provision of an improved arrangement of hair up-raising brushes spaced by a shearing head or heads, and to provide a general improvement in the shaving operation in a simple and eflicient manner. Other objects will become apparent from the description taken in connection with the accompanying drawing.

As I have pointed out in my hereinbefore referred to copending applications, I have found utility in the combination in a shaver of a shearing head and a hair up-raising brush having a longitudinal series of flexible bristles extending lengthwise with the shearing head, the bristles being suitable for skin engagement and being suitably spaced from the hair-receiving openings in the shearing head so as to avoid blocking the entrances of the openings when the bristles are flexed towards the shearing head as the shaver is moved on the skin with the brush bristles and the shearing head in simultaneous engagement with the skin during the shaving operation.- Principally, the brush bristles are useful for dislodging or sweeping from the beard or skin grit or flint-like particles to minimize or prevent damage to the shearing or cutting members of the shearing head, for tautening the skin in advance of the shearing head, especially in the localized areas closely adjacent to or immediately ahead of the shearing head and for, importantly, dislodging, erecting or deflecting, or otherwise disturbing the positions of the hairs on the skin, particularly hairs lying close to the skin in curled or slanted positions, to facilitate the entrance of such hairs into the shearing head, and for, also importantly, lifting short hairs in the direction opposite to their direction of growth to position these short hairs in a more erect position ahead of the shearing head and for similarly lifting and bending backwardly longer hairs so that when released by the brush bristles these longer hairs will spring back towards the shearing head to facilitate their entrance therein and to present themselves in more erect positions to the shearing members.

The present invention is shown herein as including parts, for purposes of illustration, but not limitation, of an otherwise well known and commercially presented shaver of a type commonly called a multiple shearing head shaver.

Referring more particularly to the drawing herein:

The shaver shown in Figs. 15 inclusive, has the usual casing-handle housing the electric motor, the casing being longitudinally divided into sections oppositely disposed and fastened together by screws of which an upper set 20 are shown. At the top or head end of the casing handle, spaced

shearing heads

21 and 22 are detachably seated with their ends closed off by pocket members connected to each other by expansion springs ofa whisker clippings catching device 23 detachably secured to the shaver in the well known manner.

Shearing heads

21 and 22 are of similar construction and comprise outer shear members 24, having hollow portions extending up from base block portions, which on their top portions are longitudinally channelled to present on opposite sides of the channels two rows of hair-receiving

slots

25 and 26 which rows are transversely spaced from each other by longitudinally extending webs of solid metal, slots 25 being longitudinally offset to slots 26 and extending from the top. or skin engaging portions of the members down into the side portions thereof, and slots 26 extending in the opposite direction and down into the side walls of the channels.

Slots

25 and 26 form the combing and shearing bars in the outer shear member for shearing cooperation with the movable inner cutters 27 which are transversely slotted as at 28 to form rows of cutter bars to coact with the shearing bars in the outer member. The

inner-cutter is held spring pressed upwardly against the inner surfaceof the outer member by spring-devices housedinandprojectingupwardly from the base blocks. The shearing heads I are vdetachably -held-- seated on i the head end of the shaver between casing wall portions thereof by fastening devices made up of U-shaped, bell-like s'ided clamp springs-and-screws 29, the screws extending into-sockets-in the casing with the" heads of the screws holding theclamp springs sides spread apart with edges off-the sides of the clampsprings engaged-into slots'in --.the sides 'of hollow portions of the outer-shearmembers, 'these fastening devices being located substantially centrallybf thelengthwise dimensions of the heads. The base"='block'-portions of the shearing heads are centrally providedwith-holestherethrough and throughwhich ex- ---tend-oscillator-hars which extend into the inner cutters, in h'oles therein; to engage and longitudinally reciprocate the' -inner'cutters as the bars' are oscillated or rockedby Athe -electric motor. Between shearing heads 21 and 22 -andina-centraL-headseat of the-shaver is seated a hair npJaising-bruslr 31'having a longitudinal series of flexible abrist-les 32-for engaging the beard and skin simultaneously with the-engagement of the beard and skin bythe shearingaheads during the shaving operation to'cooperate with -whicheverof the heads becomes the trailing head accordingttosthedirection'inwhich theshaver is moved on-the -skin. "Brush 31 is preferably of the tufted type, the e-brist-les being stapled in tuft forms in shallow sockets forming a longitudinal row in a rectangular bristle holdin'gblochwhichonits bottom face has apositioning slot 33 extending transversely and which receives a ridge-like atran'sverse positioning shoulder, not shown, in the brush -'seat onthe -head end of the shaver. On transversely opposite sides and centrally disposed longitudinally, brush '31 has-- fastening member receiving slots or grooves 34 into"'-which the 'side edges of the spring clamps ofthe fastening' devices 29-project to engage 31- and hold same in its seat-similarly as the heads are held in their seats. Slots "34 are shown herein as wheel cut, or ground, grooves. Centrally'disposed in thebristle holding block of brush 31",and, extending upwardly therein from the bottom face 'thereof is' an oscillatorbar-receiving hole35 which 'is ""'deep enough and otherwise large enough to permit the middle oscillator bar toberocked back and forth freely -relatively to the brush and together with the side oscillator ;bars by the :electric motor. Brush bristles 32 extend 'upwardly beyond'the shearing bars of the outer shearing -member of the shearing heads and are substantially centrally disposed between, or symmetrically spaced from,

,the shearing heads. T he bristles may be of'any suitable material, natural or synthetic, and are preferably closely :enough groupedinthe individual tufts and the tufts close l-eno ugh to-gether to engage all hairs within the longitudinallimits of,the bristleformation to .make a clean isweep,,vso to speak, of the beard and/skin areas in "the limits.

Referring particularly to, Fig. 5, it will be, observed ,that' if the shaver is moved on the skin in a direction to the readers right shearing head 22 will be the leading head and bristles 32-will be flexed in the direction of'the trailing head as indicated by the arcuate dash line directed from the bristles to the readers left, and it will be noted particularly that, when so flexed, the bristles are still spaced from the sides of-the trailing head by a suitable spaceindicated at 36, so as not to block ,the entrances of .the hair-receiving openings or slots in the head; similarly, .it will be noted, .when the shaver is moved on the vskin .to the readers left the bristles will be flexed in the direcvtion-towards the-now trailing shearing head 22. as indicated, by the arcuate dash line directed from the bristles .tothe ,readers right and that; when so flexed, the bristles ,arestill spaced;.from the sides of the trailing head. 22 byte suitable ,space indicated at 37 so as not to block the aentrances of the hair-receiving slots in 22. -It is-well knowmthatthe strength of beard hairs and, the shaving sb'abits of, persons. arenot. .the same ;for -.all individuals mhosgshave-Zand,-=itherefore, in. commercial presentations,

-models,--one -having relatively -longer bristles so-that

spaces

36 and 37 will be narrower for the daily shavers very short beard growth, and another having relatively longer bristles so that

spaces

36 and 37 will be Wider for the longer beard growth of persons who shave less frequently, for example, once a Week. As shown herein,

spaces

36 and 37, as a-general rule, are wide enough to allow beard hairs of several days beard growth to be entirely released or freed from'the bristles 32 before the trailing shearing head reaches a given hair to permit the freed hairs to spring back towards said shearing head to provide opportunityfor'the shearing members. to shear the hairs during their-spring back and while in a relatively more erect position; the person who shaves daily can attain the same results with his shorter heard by moving the shaver relatively faster on his skin to compensate for the time element in the spring back of his hairs. It is -also-well knownthat the-sensitivityof the skinvaries in individuals and, therefore; I} prefer to provide a not unnecessarily excessive number of bristles in the tufts,-that is, in the individual tufts. The material of which the bristles. are composed and the thicknessor diameter of the individual bristles may be related to the-exposed =lengths of the bristles, for example, but not by-Way of limitation, in some instances nylon brush'bristles may be the materialand the diameter of the filament may be .004 ofaninch, inotherinstances the same material may beused andthe diameter'of the filament may be :005 of an inch.

"Shearingheads' 21 and 22'have substantially the same dimensions andmay beseated in interchanged positions,

-ribs'-or other-projections'on the inner face; in instances 'where-thebristle block maybe shorter than the heads; the spacing ofthe endsfrom 23 will-be large enough to avoid catchinghairs and pulling them. Therefore, -it Willbe observed that'the user may changethe arrangement-of brush andheads, for example, by seating the brush and head 22jin interchanged positions as shown in Fig. 6, or

'that the shaver may be presented-commercially in a less expensive formyinitiallygby substituting a brush'for a head as shown in Fig. 7; both brushes being similar to 31.

"In the modification shown in Figs. 8, 9' and 10, the shaver (otherwise similar. to the shaver shown in'Eigs. 1'5"inclusive) shown, in addition to the .side shearing heads andthewbrush between, is provided with a'hair np-raising brush'38 positioned on the side of the easing, outside thereo n, with the flexible bristles'39 of the brnshdisposed spaced from and alongside a side of {shearing head 21a and extending upwardly therebeyond ,aj'distance substantially the same as the distance therebeyond that ,hristles 32a, between '

heads

21a and 22a, extend. Brush .38', has its stifi, bristle holding, block fastened on. adedge 40 of. a brush supporting frame .by

detachable screws41 and from the ledge a pair of ledge supporting-arms '42 extenddownwardly and the ,outermarginal. edges of 42areinturned to provide casing-abutting feet-or leg portions- 43 which hold the remainder of the frame. out 'of engagement with the eas- 1 ,ing to bridge over curved surfaces or corrugations. 'The .frame is. fastened to the. casingby screws 20a (which ,are relatively longer than and substituted-for screws .20, Eig..1)-.and provides a steady support for the brush. -Bristles .39 may be of any suitable material ofany .suitablefilamentdiameter and. are relatively longer than the. bristles. 32a; in [the forlnas shown, bristles, 39 are preferably. nylonbrushbristles having a filament diametenof .005 of.an.inch;.and, as will be observed, upon particular. reference .to' Big. 10, if theshaver ismoved mlthet'skinlini a.dir,ection tothe, readers left,.. bristles 39 will be flexed in the direction of head 21a as indicated by the arcuate dash line directed from the bristles toward 21a and that, when so flexed, the bristles are still spaced from the hair-receiving slots and shearing bars of 21a so as not to block the entrances of the slots and to provide the space 44 between the tip ends of the bristles when flexed and the hair-receiving slots. In some instances, the brush supporting frame may be modified as shown in Fig. A and in which ledge 40a of the frame may be shorter and have on its front edge spaced upwardly bent tongue portions 45 and to which may be fastened, by screws 41a extending into the bristle holding block thereof, a substituted brush 31a, of similar dimensions and similar in other characteristics to previously described brush 31, the distance from the bottoms of the brushes to the tops of the bristles in Figs. 4, 10 and 10A being substantially the same and the ledge angle of the frame in 10A being compensatory to the relative difference in lengths of bristles between 31a and 38.

Referring again to Figs. 8, 9 and 10, it will be clear, since it is common and best practice, in dry shaving, to move a shaver on the skin in alternately opposite directions during the shaving operation, that, When the shaver is moved on the skin in the direction to the readers right, bristles 32a, of the brush disposed between

shearing heads

21a and 22a (Fig. 10), will erect beard hairs for entrance into the slots of shearing head 21a substantially similarly as will bristles 39 of the side brush when the shaver is moved on the skin in the direction to the readers left.

In the modification shown in Figs. 11, 12 and 13, the shaver (otherwise similar to the shaver in Fig. l) is provided on opposite sides thereof with adjustably positioned hair up-raising brushes having

flexible bristles

39a and 39b. These brushes are similar and the supporting and adjusting mechanism of one is similar to the adjusting and supporting mechanism of the other. The mechanism comprises a base portion or member 46 having opposite marginal ends inturned to abut the casing; oppositely disposed end bearing blocks 47 are secured to 46, each by a pair of longitudinally offset screws 48 extending into the blocks on opposite sides of centre of the blocks; an intermediate or central bearing block 49 is secured to 46 by spaced screws 50, and in these aligned blocks, extending therethrough, are longitudinally directed, coaxial, cylindrical holes receiving, for slidable movement therein, stepped

cylindrical rods

51 and 52, the large cylindrical ends of the rods being received in end blocks 47, the opposite and smaller cylindrical ends of the rods being received in block 49. On their upper sides, blocks 47 are provided with longitudinal slots into which holding pins 53 project from the large end portions of 51 and 52 to coact with the side walls formed by said slots to prevent rotation or turning movement of the bars. Between the large and small ends of 51 and 52 are intermediate cylindrical portions which are externally threaded for a suitable portion of their lengths, the threaded portion of 51 being a right hand thread in cooperative threaded engagement with an internally threaded block 54 and the threaded portion of 52 being a left hand thread in cooperative threaded engagement with an internally threaded block 55;

blocks

54 and 55 being on opposite sides of block 49 and being connected to the brush carrying bars 56 by spaced screws 57 and secured against any tendency to turn thereon by pins 58 extending from 56 into 54 and 55; bars 56 have longitudinally spaced internally threaded holes 59 in threaded engagement with screws 41b extending from the bristle holding blocks of the brushes. Surrounding the intermediate portions of 51 and 52 between their large end portions and blocks 54 and 55 are compression springs 60 bearing in one direction against

blocks

54 and 55 and in the opposite direction against theannular shoulders or flanges at the inner ends of the large cylindrical portions of screw bars 5i and 52 to tighten the threaded connections between 51 and 54 on one hand and 52 and 55 on the other by tending to force the screw bars 51 and 52 outwardly. Coil springs 60 are at all times under compression. The longitudinal central portion of bar 56 is, in each case, approximately as wide as the bristle holding blocks of the respective brushes, but at longitudinally opposite marginal ends, these bars are wider, preferably, to provide inward projections or extensions having, preferably, spherically curved inner edges; these extensions serve as stops to abut suitable portions of the casing to limit inward movement of the brushes towards the shearing heads, the stops being indicated by 61. A relatively long pair of screws 20b connect the casing sections and fasten one of base members 46 on one side of the shaver; a relatively shorter pair of screws 20c, coaxially oppositely disposed to 20b, are screwed into threaded holes in the casing and fasten the other of members 46 on the shaver. To adjust the position of the side brushes, the user will seize the ends of the brushes to manipulate the movement; as a side brush is pulled outwardly or pushed inwardly, as the case may be, central block 49 and blocks 54 and 55 will help to guide the direction of pull or push. As a brush is swung outwardly screw

bars

51 and 52, by their threaded connections with 54 and 55, are caused to slide longitudinally outwardly, their slide movement being guided by the pins 53 and the slot walls in end blocks 47, the pins and walls also serving to prevent rotation of 51 or 52, and the outward slide movements of 51 and 52 lessen the compression of coil springs 60; because of the small threads on 51, 52, 54 and 55, for example, in the proportions of forty-eight threads, or, if desired, fifty-six threads, to an inch, the slide movement distance of 51 and 52 is very slight and, consequently, only a slight amount of coil spring compression is released, so that, while the compression of springs 60 varies according to the distance a brush is moved in either direction, there is always sufficient compression to retain the brush in its adjusted position. Referring particularly to Fig. 11, the brush on the left side is shown in solid line adjustably positioned pulled laterally outwardly somewhat so that its bristles 39a, when flexed by the skin, will be laterally spaced from the corresponding side shearing head by a space indicated by 64, between the tips of the bristles when flexed and the side of the shearing head, suitable for a beard growth of a person who, for example, shaves every other day; to expose the shearing head to his vision to trim a mustache, the sideburns, shave near his nose, or dust out his beard before shaving the brush may be adjustably positioned retracted aside as shown by the dotted outline 62; the brush may be turned down to the retracted aside position shown by dotted outline 63, its downward limit; the brush may be moved towards the shearing head until the stops 61 engage the casing and at this adjustment will have the same relative position as the brush shown in solid line on the right side has and will be in its most tightly retained position. The brush on the right side is shown in solid line adjusted to its maximum closeness to the corresponding side shearing head so that its bristles 391), when flexed by the skin, will be spaced from the shearing head by a space indicated by 67, between the tips of the bristles when flexed and the side of the shearing head, suitable, for example, for a person who shaves daily; for longer hairs, beard or other body hair, the brush may be adjustably positioned, for example, further out laterally as indicated by the dotted outline 65, or it can be adjustably retained in the retracted aside position shown by the outline 66.

In using the word bristles in the claims, I wish it to be understood not in the narrow sense only as conmoting only-hairs and onlynhairsrderived fromuanimals 3'01 z-plants, but to ,include, a lso,:anyvother, naturalsor synthetic material suitable for brushing the "beard and skin-10fa person in the -:manner; and-for thepurposes ,which haverhereinbefore beenzdescribed; and,,in':using the word brush in theclaims, I WiShxit- 818010 be understood-as not being limited to an=instrument com- EpOSCdOf hair bristles, but-to include, also,-':an'instrur-rnent eomposedof any other material, natural'or synathetic, in filament, or threadlike, or fibrelike form,of anywsuitable thickness or diameter, --which is arranged :,as are-bristles=in the ordinary brush-and whichmaterial randits-arrangementare suitable for-brushing the beard a-ndz-the skin ofa person in -the"man-ner and' for the p,,urp0ses which have hereinbefore been described.

In a dry shaver, in combination, a skin-engaging shearing head, a hair up-raising brush disposed alongside one side of the head and a movably mounted hair up-raising brush disposed on the opposite side of said head, the brushes having flexible bristles adapted for travel on the skin simultaneously with the travel on the skin by said shearing head as said head is engaged on the skin in the shaving operation, means for adjustably spacing said movably mounted brush laterally from said head with said bristles of said movably mounted brush disposed alongside a side of said head for simultaneous travel on the skin therewith during the shaving operation, and means for releasably retaining said movably mounted brush so adjustably spaced laterally from said shearing head.

15. In a dry shaver, in combination, a skin-engaging shearing head, a hair up-raising brush disposed alongside one side of the head and a movably mounted hair up-raising brush disposed on the opposite side of said head, the brushes having flexible bristles adapted for travel on the skin simultaneously with the travel on the skin by the shearing head as said head is engaged on the skin in the shaving operation, means for adjustably spacing said movably mounted brush laterally from said head with said bristles of said movably mounted brush disposed alongside a side of said head for simultaneous travel on the skin therewith during said shaving operation, or for adjustably positioning said movably mounted brush retracted aside to expose said last said side of said shearing head, and means for releasably retaining said movably mounted brush so adjustably spaced laterally from said head or so positioned retracted aside.

16. In a dry shaver, in combination, a pair of spaced, skin-engaging shearing heads, a hair up-raising brush disposed between said heads, side hair up-raising brushes in said shaver spaced from each other by said shearing heads, the three said brushes having flexible bristles adapted for travel on the skin simultaneously with the travel on the skin by said shearing heads as said heads are engaged on the skin in the shaving operation, one of said side brushes being movably mounted, means for adjustably spacing said movably mounted brush laterally from the adjacent shearing head with its bristles disposed alongside a side of said adjacent head for simultaneous travel on the skin with said heads as said heads are engaged on the skin in the shaving operation, or for adjustably positioning said movably mounted brush retracted aside to expose said side of said adjacent head, and means for releasably retaining said movably mounted brush so adjustably spaced laterally from said adjacent head or so positioned retracted aside.
