ATTORNEYS.

United States u? 'ELECTRIC HAIR CUTTERJAND DRY SHAVER *This iinventionrelates to -an electric 'hair cutter and fbdrycshaven particularly of the type in which the device f `comprises a cutterhead including an outer stationary cutterhaving perforated surfaces to engage the surface *ofthe skin,` and an inner movable cutter engaging the inner-surface of the outer cutter andcooperating therewith forproviding ashearing action for` cutting the vhairs. It ha"s for an object to provide a device of this `characterwwhich will trim or cut long `hairs as well as vshaverthe shorter hairs as in the usual close shaving 1 operation, land Ahas for another object to` provide an improved `cutter head of the type in which there is a single stationary outer skin engaging cutter-or guard, but hav r ingtwo separated perforated cutter surfaces both of "which are capable of cooperating for close shaving operations, rand` one ofwhich has `an yadditional capability of trimming or cutting long hairs either of a beard which has beenallowed tov grow, or the hair on the head in- 4cluding cutting or trimming the hair at the back of the rneck or on the sides of the head, or cutting the hair from legs and arms.

t Another object isl to provide a new construction in wwhich the hair cutting action can-be` secured to effe@ tively shear the hair in both up and down strokes of @the device, and` which` will have an improved combing action to direct the `hairs into direct cutting relation to x the shearing `elements for more eflicient and effective :wcutting ofthe hair.

The device comprises an enclosing housing 1 of any suitable material, preferably a suitable molded plastic material to enclose anyrrsuitable `or standard type of electric motor Z and form ahand grip for operating the device. The motor. includes the usual rotary arrnature 3 in the laminated pole or eld elements 4, and

`includes a shaft projecting from the armature at its upper end, a`s indicated at 5, adapted tobe connected with the movable cutter for operating it; The cutter i head is mounted-on `and secured Ato the motor to form i a structural part thereof by means of a molded plastic block 6 secured to: the upper end of the motor by any suitable means, such forexamplev as the screws or bolts 7 securing the laminationstogether and having threaded i projecting/end portions passing through openings in the i block and mounting the block on the motor by means of suitablenuts 8 in recesses `in the upper and lower f surfaces of the block. `The improved cutter head comprises an outer stationary cutter 9 and an inner movable cutter assembly 1l)` within" the outercutter and having cutting means cooperating with the outericutter to secure the shearing action for cutting the hairclosely in the hair `cutting operation. The means for mounting these cutter elements including both the inner and outer cutters, comprises a baseor supporttll preferably of suitable molded plastic materialseating on` the top of the block 6 `and having downwardly extending end mern bers` 12 lyingagainst or` embracing the opposite ends of `the `block 6 and secured thereto by any suitable means f lower plate `or angenportion `15.""'I`his body portion is of smaller size` than the ilauge portion 15, thus prov1ding ledges or shoulders 17 on which the outer sta- `tionary cutter 9 maybe mounted."` The upper surface or` top `wall of the body portion 16 is provided with laterally spaced longitudinalr open channels or grooves I8` forming guide.means'for'stabilizing and guiding the longitudinal reciprocating movements of the inner cutters. -The inner cutterassembly comprises a support or carrier -19 preferably also molded of suitable plastic `material and provided with means -for mounting and carrying the `innercutter members 2l) and 21.

The outer o1` stationarycutter 9 is formed of hardened steel ground to a suitable finish `with thin outer skinengaging oncutting surfaces'to` secure a` 4close shaving t operation, ,the various thicknessesbeing, of course,;great 1y exaggerated on the` drawing." It comprises a plurality of top perforated skinfengaging surfaces,preferably` two, as indicated -at- 2.2` and23, separated'by alongitudinal open channel `24. Thezsurfacef22--may beqprovided with any suitable-shape or form of-.perforations `for securing a close shavingoperation. In `the formwshown they comprise a series of openings 25`which may be either circular, oblong,

`.elongated slots; or. thehlike, and `the surface -23 isV in the form of a subst-antially longitudinally extending rib shaped portion, preferably with a flat outer skin-engaging surface 26, and provided with perforations comprising a series of transverse slots 27 separated by transverse cutting blades 28. It will be seen from Figs. 2 and 3 that both the

portions

22 and 23 are in cross section substantially inverted U shape, including substantially parallel side members 29 and 30 for the portion 22, and 31 and 32 for the portion 23. The inverted U or rib-shaped portion 22 is wider than the inverted U or rib-shaped portion 23. This is so that the portion 22 may be provided with two sets of shearing surfaces 33 and 34 separated by an imperforate portion 35 each adapted to cooperate with a separate inner cutter member 20, thus providing a larger shaving surface for engaging the skin and securing the shaving operation. The slotted portion 23 is of a width for cooperation with a single inner cutter element 21, which, however, is the same as the cutter elements 20 cooperating with the separate portions of the wider cutting surface 22. These inner cutter members are shown in detail in Figs. 8, 9 and l0, and are stamped from thin sheet hardenable steel to form a blank 36 with longitudinally projecting lugs 37 at its opposite end corners, and its intermediate portion provided with a series of transverse elongated slots 38 separated by the transverse bars 39, which, however, are later ground from the lower or inner side with tapered side walls 40, thus providing the transverse bars 39 for cooperation with the cutter surface 23 with sharp shearing edges 41. The blank may be folded or formed into the hollow cutter of Fig. 8 of inverted U shape in cross section, with the lugs 37 folded inwardly and overlapped at the opposite ends thereof to strengthen and stillen the cutter, and with the slots 38 and the cutter blades 39 at the top surface and connecting the side members. The slots 38 are of a length to extend at their opposite ends a suitable distance downwardly into the side walls 42 of this member, as indicated at 43, to thus also carry the cutter blades 39 into the side walls and provide cutting edges at the upper portions of these side walls for a better shaving and cutting operation, particularly for longer hairs, as will later be described. These two different designs of shaving and

cutting areas

22 and 23 also make it possible to shave with two differently perforated surfaces at the same time and thus gain greater speed for the shaving operation than could ordinarily be possible with present types of guards having only a single design of perforated guard shaving surfaces. This design also provides means for accomplishing a cleaner close-to-the-skin-line shave as a result of having the two differently designed outer cutter surfaces. It is a scientific finding that the beard is of triangular shape Iand lies in different directions, and the advantage of having two differently designed perforated surfaces and openings for receiving the beard permits the cutting edges of the different perforations to attack the beard from different angles during the exceedingly fast reciprocating movement of the synchronized cutting action.

The carrier 19 for these blades or inner cutters, as previously indicated, is preferably of molded plastic material, and has a pair of laterally spaced longitudinal ribs 44 on its under side guided for longitudinal sliding movement in the channels 18 of the block 6, these being of a width to have good sliding tit in the channels 18 and properly guide and position the carrier 19 and cutters 20 and 21 in the shaving operation. On its upper side this carrier is provided with a plurality of longitudinally extending ribs 45 and 46. The ribs 4S are laterally spaced to carry the inner cutters 20 under the perforated shaving portion 22 of the outer stationary cutter, while the rib 46 is to carry the cutter 21 under the perforated portion 23 of the outer cutter. The cutters 20 are seated on the ribs 45 and embrace them with their opposite side walls, the ribs 45 being of less height than the cutters so as to provide a clear space 47, as shown in Fig. 2, between the cutting blades 39 and the top of these ribs to permit transverse passage of a suitable cleaning brush to clean out the CII cut hairs from the inside of the inner cutters. The cutters are secured on these ribs by suitable means, such, for example, as screws 48 passing through the openings 49 in the lugs 37 and overlapped at the end walls of the cutter, and threaded into suitable tapped openings 50 in the end walls of the carrier.

As the other cutter 21 is within the outwardly inclined portion 23 of the outer cutter the rib 46 has similarly inclined side walls `and shoulders 51 on which the cutter 21 is seated, and it is secured the same as cutters 20 by screws 43 passing through the end walls 37 and threaded into the ends of the carrier. This portion 23 is inclined outwardly away from the portion 22 to secure a better guiding effect for the blades and slots of the outer cutter to better guide and direct the long hairs into these slots 27 for the cutting or shearing operation. This also inclines the top flattened wall 26 downwardly and outwardly, but the side walls 31 and 32 are made somewhat longer so that the top tlattened wall 26 is spaced above the level of the perforated portion 22 to also facilitate the cutting of the longer hairs, and also to act as a guide for the perforated portion 22 and further act to stretch the skin and draw it flat to facilitate the shaving action of the portion 22. As the side walls 31 and 32 of the portion 23 are longer to carry the perforated flat wall 26 above the level of portion 22, the rib 46 is also somewhat higher than the ribs 45 to properly position the cutter 21 with respect to the higher portion 23. This inclined arrangement of the portion 23 together with the channel 24 provides a device which can shear olf hair in both the up and down strokes, the hair being combed into the cutting slots either through the channel or outer tilted edge. Also raising the handle up and down while the cutting edge is engaged, grades the hair. Turning the device over and using a down stroke with the handle in an upward position creates another different angle for cutting and grading the hair. Because of this easy maneuverability the device offers several new angles in which the tilted edge can be used for excellent hair grooming. Only the cutter used in the position for cutting hair uses the particular advantage of the extended side blades 43. This is to permit the long hairs to lie down into the slots between the blades, and through the reciprocating action, the hairs cross the path of a similar pattern of cutter bars on the beveled edge of the guard for a very effective shearing action. As the guard is run through the hair it is also combed into the U- shaped channel 24 and directed into the path of the Shearing edges of the guard. The inner cutters are interchangeable for longer service. The distance over which the inner cutters travel during their reciprocating movement should be far enough to have the inner hair clipper cutter travel across two complete slots in the guard. This distance will also be sulicient to apply to the otherperforated shaving area 22. From the fact that in cutting the hair the shearing edge of the guard acts as a comb, it is possible to grade or taper the cutting process to give a fully groomed appearance. To accelerate cutting long hairs close to the skin line, after trimming it short with the edge portion 23, it is only necessary to make a flat contact with the shaver area 22 while moving the device back and forth. The upward and outward slanted hair cutting edge or portion 23 picks up the long hairs comblike and lays them crosswise into the open slots between the blades for instant shaving. The tilted right angle edge plus the side cutting action of the inner cutters registering with the cutter blades in the outer guard or cutter insures excellent shearing results of long hairs.

The side walls 29 and 32 of the outer stationary cutter 9 are made of a height to enclose the base portion 16 and the inner cutter assembly 10 and are provided with outwardly extending llanges 52 on their lower edges seating on the top of the flange portion 17 and secured thereto by suitable screws 53 passing through these flanges and threaded into suitable tapped openings 54 in the llange portion 17. These flanges 52 may be strengthened by folding them `backwardly on'themselves. as indicated `in f Figs. 2 and 3. The side walls 29 and 32 are inclined downwardly andoutwardly to provide a clearance and prevent friction on the sides of the` carrier 19 and also improve the appearance' of the head.

Suitable means are provided for `supporting and reciprocating the inner cutter assembly during the shav- `ing operation. For this purpose there are mounted in the body portion 16 of the base 11 a series of spring-pressed balls 55. These are mounted in `tubular sleeves 56,

" inserted in the openings in the member 16 with a tight tit or molded therein, and having their lower ends turned inwardly somewhat to provide a support for a thin metal disc 57 which when forced intoposition is dished somewhat, as shown in Fig. 1, so that as it tends to flatten it is pressed against the sides of the sleeve 56 and is held therein. Supported by `this disc is a coil spring 5 8 pressing .at itsupper end against the under side of the ball 55, and the upper end of the sleeve 56 is extended inwardly somewhat at 59 to overlap the ball suiciently to retain it in j the sleevewith a portion of the ball projecting above the ,end of the sleeve'and above the top surfaces 60 of the bodyportion 16. rl`he carrier 19 for the inner cutters rests on the `top of these balls with its guide ribs 44 in and guided by the side walls ofthe channels 18. In this position the .g inturned ends of the `sleeves 56 are spaced above the balls or theballs are depressed somewhat so they are free and are yieldably held against the under side of the carrier 19 by the springs. The inner cutter assembly is therefore yieldably supported on these balls 5S for longitudinal reciprocating movement to reciprocate the inner cutters `20 and Z1 at the innersides of the perforated portions 22 'and23 of the stationary outer cutter for the cutting `and shearing operation, and the springs supporting the balls 55 will secure the proper pressure of the inner cutter against theouter cutter for the proper cutting or shearing operation and will maintain this pressure indefinitely and to compensate for wear between the cutters. The balls 55 also provide a rolling or antifriction bearing support for the inner cutter assembly to reduce friction and facilitate the reciprocation of this assembly. Suitable clearance is provided at 61 between the lower edges of the ribs 4 and Y the bottoms of the channels 18, and a similar clearance 62 between the under sides of the carrier 19 and the top of the body portion 16 to permit downward yielding movement of the inner cutter assembly and provide free movement of this assembly. With this arrangement the three separately spacedidentical inner cutters are reciprocated in synchronism while mounted upon and carried by a single resiliently mounted plastic supporting member.

` This inner cutter assembly is reciprocated longitudinally within the outer cutter 9 by an eccentric cam 63 secured to the upper end of the armature shaft 5 of the proper clearance.

motor for operation thereby. It is mounted on a downwardly extending supporting stem or shaft 64 having a square tapered lower end 65 set into a similarly shaped and tapered opening or socket in the end of the shaft 5,

and this stem or shaft is supported in a suitable bearing sleeve'66 in the base 11. The eccentric cam 63 extends into an elongated recess 67 in the under side of the carrier i 19 which is lined with a metal sleeve 68 for a bearing for theeccentric cam, and the cam is wide enough to extend a short distance into a recess 69 in the top of the base 11, but is spaced from the bottom of this recess for Mounted in this eccentric cam 63 is a spring-pressed ball70 mounted in a suitable sleeve and supported by a spring thesame as the balls 55, to press against the top of the recess 67 to help support the carrier 19 and also `to retain the stem or shaft 64 of the cam ff inits `socket in the shaft 5 of the` motor. This provides anoiseless cam action for operating the inner cutter.

At the opposite ends of the outer and inner cutters are bins or so-called whiskets for receiving the cut hairs and y retaining them until they are removed by the cleaning operation. An effective form for these bins or whiskets is shown in Figs. l and 4.` Vtcomprises a member l7Lot' soft resilient rubber provided with a flanged base `72`to seat on and be cemented to the top 73 of the endportions of the flange 15 of the base member 1.1, and the upper portion of these members 71 is given an outline, as shown in Fig. 4, to correspond with the end outline of the outer stationary cutter 9, including a wider fiat rib portion I74 to correspond with the end of the perforated portion 22, and a narrower outwardly inclined higher portioir75 to correspond with the rib portion 23 of the outer cutter and separated from the portion 74.by an upward facing recess 76 corresponding to the channel 24 in the outer cutter.

On its inner wall is a recess to provide a chambery or vto be shifted downwardly and `outwardly to. expose the cavity 77 for easy removal of the hairs accumulated therein, and when released the resilient action of the rubber will shift them back to the closed position of Fig. 1. The open recesses 76permit the passage of a suitable cleaning brush through the channel 24 for a cleaningoperation, and after these `members 71 are swung downwardly and outwardly this or asimilar brush may be easily passed longitudinally through the clearance spaces 47 within the inner cutters for a similar cleaning operation. These soft rubber bins will also act to greatly dampenthe chatter commonly developed in this type of device.

Suitable electrical connections tothe motor may be provided in the usual manner, as for example by providing the lower end of the shell or casing 1 with a suitable hollow boss 1a to receive a plug-in connection (not shown) by which the shaver may be plugged into any suitable electric wall or other outlet for operation `of the shaver.

It will be understood from the above that this provides a very effective and simple construction for performing the dual operations of close shaving `the face or other surfaces, and either simultaneously or separately permitting the cutting of longer hairs such, for example, as whiskers which have been allowed to grow, or the hair of the head, including trimming at the back ofthe neck and the sides of the head.` Both

perforated portions

22 and 23 of the cutter head may be used for close shaving of the face7 the narrower outwardly inclined slottedportion Z3 not only shaving with the wider portion 22 but also acting as a guide for the portion 22 and as a means for drawing or stretching the skin taut and attening it for a more effective shaving by the portion 22. Theperforated portions will operate with movements of the cutter in both directions, but in cutting the hair the narrower por tion 23 may be used either above or below the portion Z2. Also by varying the angle of inclination of the cutter head as it is moved upwardly and downwardly in the hair cutting operation, the action of cutting the hair maybe effectively controlled. The separating channel 24 and the narrower shape and inclined raised portion 23 as well as the inclined outer surface 26 of this transversely slotted portion 23 has an effective combing effect to raise and position the longer hairs and properly direct` them to and place them in the slots 27 in the outer cutter for most effective cutting and shearing by both the portions 43 in the sides of the inner cutter and the transverse portions or blades on the top flattened portion of 'the cutter. The inclined hair cutting portion 23 will stretch the skin ahead of the trailing shaving surface 22 and thereby render the skin taut prior to the actual cutting action while shaving. The inclined portion 23 and slightly elevated edge26a gives the effect of a double' stroke each `time the shaver is moved once over the skin; The facial contours are flattened out and the beard sheared ahead of the actual close shaving action. it will be seen the structure is a very simple one, involving a minimum number of parts which may be manufactured and assembled at relatively low cost,

and as the mounting and carrying portions may be made of suitable plastic materials such, for example, as the phenolic condensation products, vinylites, acetates and like materials, they are of light weight to facilitate proper operation and use of the device and also to reduce its manufacturing and maintenance costs. lt permits easy assembly and disassembly for inspection, cleaning and repair. While this device provides an excellent shaver which will give a very satisfactory close shave, it also provides means for the user to easily cut or trim long hairs with the same good results as obtained from a conventional hair clipper. The hair cutting edge portion 23 of the guard is especially designed to lift and guide the long hairs into the cutting slots and blades. This device is also particularly adapted for removing hair from legs and arms.
