the top unit of Fig. 1, showing a modified shape and a modified form of teeth structure. and illustrating one arrangement of light passages in the stationary and movable cutter members and one arrangement or the ball bearing of the tensioning means in the stationary cutter.

' Fig. 9 is an enlarged,'sectional'viewthrough the. teeth of the movable member and the overhanging flange portions of the teeth of the stationary member of the top unit shown in Fig. 8, showing greater detail of the undercut teeth structure of such top unit and their cutting action;

Fig. 14 is a side elevation of Fig. 13, showing the slots or grooves may be disposed in an angular manner or fashion; and

Fig. 15 is a detailed, perspective view of Fig. 13. Referring to the drawings, (Figs. 1, 2 and 4) K indicates the assembled instrument wherein the numeralv 5 shows a motor-containing handle light reflector, which may be in the form 01- a box 8, may be positioned within the recessed section I. Members 8, adapted to receive illumihating means, such as, for example, bulb H, are

positioned within the box 8. Such bulb H may be of any suitable style or shape. A transparent element I2 may cover the box II and may be held in place by friction fit or by extensions I4 fitting or snapping over the thickened edge sections l5. 1 Y

In an instrument of thetype shown in Fig. 12, the light reflector 8 may be positioned between the units A and B, and the illuminating means or bulb it may be held therein in the same manner and for the same purpose as in Fig. 2. Such bulb Il may be held in position by' friction fit within the portions 9' of elements 8 (Fig. 2A). These elements! are suitably insulated, in a. manner Fig. 10 is a view similar to that 01 Fig. 9, with the movable member positioned in the opposite side to that shown in Fig. 9, showing that both edges of the undercut teeth are adapted to cut the hair;

Fig. 11 is an enlarged view showing, approximately, the manner in which the hair is out by the edge portions of the upper teeth of the stationary member and by the edge portions of the undercut teeth of the movable or reciprocatory member;

Fig. 12 is a fragmentary, cross-sectional view through a modified form of instrument constructed with two separate top units which are each individually adjustable at various :angular positions with respect to the handle and which operate simultaneously at all angles, so that they may be utilized either individually or simultanereadily understood and not thought necessary to be shown, and are connected to the motor (not shown), and when the bulb l l is inserted, the side portions l I will contact elements 8 and thus close the circuit. The portions 8 will prevent displacement of such bulb H, and when it is required to remove said bulb H, the user may take any tool and place such tool in the opening 5 of the handle or casing 6, and through an opening in the box 8, the arrangement of which may be readily understood, though not shown in the drawings, and under the bulb I I and gently move the tool downwardly, thus raising the bulb II from its position. To replace the bulb H, a gentle pressure will snap the bulb in position between the portions 9' and be held 'in place.

The extensions 6 are provided with non-circular' or hexagonal nuts it, which are held in place within the molded material by means oi grooved sections I1. The shaving unit L is positioned between the extensions 6. The stationary member l8 of the said unit L is provided with depressed sections IS. The screw-threaded elemerits 2| are positioned within the nuts l6 and when they are tightened the end sections of the same will engage and press against the inner'flat wall or the recesses 19, as at 22, thus holding the unit L tightly in position. Of course, unit L may be adjusted into any desirable angular position with respect to the handle 5, for example, as indicated by the dotted lines in the drawings,-

and be held stationary in such adjusted position. The stationary member I8 is provided with teeth portions 24 and with flange sections 2!. A

reciprocatory or movable member 28 is slidably supported by the said stationary member II.

The reciprocatory member 28 is provided with the teeth portions 21 (Fig. 4). The upper faces of the teeth portions 21 frictionally engage the underi'aces of the flange portions 25 (Fig. 1).

, reciprocated, the upper faces of the teeth 21 will-v the starter flit he actuating member" 26 isput] in motion, the reciprocatory member '26 wilibe move and pass slots 26 of the flange portions 46 and cut hair entering suchslots or hair passages. The slots or. hair passages 26 and 26' are oi'..suitable length, so as to permit the hair to enter them for hair cutting or shaving purposes. The width of the teeth are of a greater degree than the width of the. hair passages, so that the teeth will not get caught within such hair passages during the operation of the instrument.

The shaving'unit L may be tapered or shaped I cross-sectionally in a manner whereby the base or bottom portionofthe same may be of a narrower width than the upper portion thereof, for example, resembling a V shape, or any other suitable style or shape, so that such bottom portion will not block the illuminati rays and will permit their passage about the unit to illuminate the section of the face being shaved. Ii desired, the center portion of the bottom sections 20 of the stationary member l8 and the portion ii of the reciprocatory member 26 may be removed,- as shown in Figs. 2 and 8, so that the illuminating means may also pass through the center section of the hair cutting or shaving u.nit, thereby providing full illumination from the handle adjacent to each side section of the unit and also through the center portion thereof.

The interior of the handle 6 is provided with the means to hold the mechanism for reciprocatving the movable member and also for supplyingenergy to the illuminating means. A portion of such mechanism is the actuating element. The as usual actuating element consists of a single section adapted to engage the reciprocatory memtheir upper end sections 42 engage'the side faces 43 of the cut out portion of the reciprocatorymember 26, so that when the bar 44. is put in motion, the upper section 45 will move the element 31 and the upper end portions 42 of the element '31 will move the reciprocatory member 26, so that the teeth 21 will co-act withthe teeth 24 and with the flanges portions 25 for hair cutting or shaving purposes.

If desired, the upper portions 42 may be 01' enlarged, arcuate outline, such as the Ian-shape shown at 46(see dotted. line indications in Fig. l), in which case the shaving unit L may be swung in any direction and yet retain the connection between the actuating means and the reciprocatory member. The fan-shaped portions 46 may be of separate or individual elements and may be inserted through the top of the opening 4| and secured to the element 31 or sections 26 and 26 by means of solder or friction-fit or other suitable means.

I1 desired the bar 44 'may be made integral with the elements 31, as at 46 (Fig. 4), and the entire elementwill move as aunitto reciprocate the member 26.

The bar 44 or the actuating means maybe provided with an opening 44'. Screw element 66 passes through said opening 44"and is positioned within a screw threaded section I of the casing 5. Terminals 26 are secured to the inner section of the casing 6. Electric wires 20' are connected to the portions 26, and when the screw element 66 is tightened, its head willengage terminals 20 and close the circuit. However, in case the screw 50 should loosen then the circuit will break and the motor will stop working, thus avoiding possible injuries to the user.

to be understood that the central bottom portions of floor sections 30 of the stationary member l6 and of the floor 6| oi the reciprocatory member 26 do not necessarily have to be removed. In such a case the bottom portion may be provided with slots 56' and the bottom portion 3| may be provided with slots 5| which are'smaller in size than the slots 50', and the upper portions 42 of the actuating means 46 engage within the smaller slots SI and move treelywithin the slots 50', thus reciprocating the member-26.

With respect to Fig. 12, it will be seen that the actuating means 48 is positioned in a transverse cross-sectional manner with respect to the handle structure and is adapted to operate or reciprocate a plurality of individual shaving units.

The end portions 46 of the actuating means 48 may be shaped in half-Ian style, or formed in any other suitable manner adapted to retain actuating contact with the reciprocatory member 26 at any angularpositionoi the L units with I respectto the handle 5.

It may here be noted that the end portion of I8, but that the opening is may be tapered or formed in a manner whereby the end section of the screw element 2] may engage the tapered side walls of said opening is, as at 5|"(Fig. 4) and thus hold the L unit in a stationary position.

It 'is really immaterial in whatever position the actuating means may be placed with respect to the handle structure, or how it may be constructed, the main object being the teaching of a mechanism for an electric hair-cutting or shaving instrument, including an actuating means comprising a plurality of sections arranged in a manner adapted to make a plurality of contacts with the reciprocatory means for reciprocating the latter for operable purposes.

The same is true with respect to the plurality of individual hair cutting or shaving units, as taught by applicant.

is arecessed space between the individual cutting units adapted to permit the skin of the face to be shaved to bulge between such units, therebyenabling such units to be utilized simultaneously upon the face tor shaving purposes, it

would naturally come within the spirit oi! applicants invention.

For example, the Figs}, 5, 6, 8, 13 and 15 teach the "novelty of having a handle provided with a plurality of individual, complete hair cutting units arranged in a manner providing a recessed It does not matter how the cutting units are shaped. As long as there while shaving, move theinstrument in either di-j or spaced section between such cutting units, and such recessed spaced section is adapted to permit theskin of the face to be shaved to bulge between said units. Thus, such units may be utilized simultaneously upon the face for shaving purposes. Fig; 12 also teaches the same novelty, namely, two individual complete shat/lug units.) A and B, spaced apart from each other in a manner permitting the skin of the face to be shaved to bulge therebetween in the space H, so that such units may be utilized simultaneously upon the face for shaving purposes. It will therefore be seen that the structure "as shown in Fig. 12 is within the spirit of the. structures as shown in Figs. 1, 5, 6, 8, 13 and 15. It is, therefore, evt- 15 dent that it is immaterial how the-individual. shaving units are constructed, but-that it is the concept of arranging such units, particularly the practicability of such arrangement, that matters. It will, therefore, be clearly seen that all oi: the above figures, namely, Figs. 1, 5, 6,, 8, 12, 13 and 15 are within the spirit and scope of the same invention. Q

' The handle may be built in azmanner adapted to hold the shaving units ,in a. .flxed stationary position. If desired, however, the handle 6 may be so built as to permit the side or pivotal move-' ment of such units. When such pivoting pro-. vision is made in the handle for a device such as shown in Fig. 12, the units A and B may each be swung side-ways to provide th handle 5 with two side hair cutting or shaving devices'which I are simultaneously operable but which maybe separately used and each of which is provided with two individual hair cutting units, so that the user may be able to switch from-one device to the other at his convenience.

It will be noticed, of course, that if the two .devices, A and B in Fig. 12, are adjusted in an upright, stationary position, the user will be pro n vided with a. maximum amount of shaving facilities. Firstly, these devices, A and B, will act as a gauge for holding the handle in proper'position against the face for shaving purposes. Secondly,- the user will be provided with four (4) individual hair cutting or shaving units, and with eight (8) shearing sections, faces or points, for the reason that applicant has found while experimenting with the within invention that the most cutting of hair takes place at each of the extreme end sections or corners of each face as indicated, for example, by I ,and F, of the upper surfaces of the teeth of the reciprocatory member, in connection with the cutting edges of the overhanging or overlapping teeth or flanges 25. And it will be clearly noted that eight (8) such extreme end sections or corners of the faces of the reciprocatory member are simultaneously in operation when devices A and B are both adjusted in up-. right position. on the handle, thus providing a maximum of effectiveness for shaving or hair cutting purposes. It can thus be plainly seen that applicant's invention is a practical and] use-' ful structure. The figures herein shown are for illustrative purposes only; and various changes 5 in detail may, of course, be resorted to without departing from the. spirit and scope of .the invention. i

It will be seen that each hair cutting unit hasa plurality of skin cag 8 88 faces, s. 70 for. example, I,- 2, '3, and C, D. and E, in Fig.5, so that the user-does not nece sarily have to hold the "instrument at any certain, particular position with respect to the face;to be shaved, and may.

'and with an opening 65,

rection and hold the same, at his convenience,-at

various angles to the face and .still retain contact between at least one of the shearing faces and the skin of the face to be shaved. The same is true with Fig. 6, wherein the faces I and J permit the changing of the position of the instrument with respect to the face to be shaved. 'The same is true with the structures showrfin Figs. 1, 8, 12, 13 and 15. They are all provided with side and upper skin engaging faces which may be each applied to the skin of the face to be shaved.

The letter N indicates the concaved, recessed or spaced sections formed or. arranged between the individual shaving units for the.purpose of permitting the ski'n of the face to beshaved to bulge therein, when both. units are simultaneously applied to the skin, to tense the skin to enable the shaving faces on each side of the spaced section to more readily'pick up thehair and to cut it more closely to the skin. It will. be seen that the edge sections 4 and P of the cutting unit L have been formed in a semi-circular, beveled, or curved The bottom portions 52 of the stationary memher it (Fig. 5) is provided with an opening 53 terminating in a restricted opening 54. A ball or bearing 55 is inserted within the opening it and is supported therein by suitable resilient means,

as for example, the spring 56. ,The lower portion. of the opening 53 is provided with a screw.-

threaded section adapted to receive a screwthreaded member 51.. The member 51 presses against the spring 56 ,which in turn presses against the ball 55, so that a portion of the ball protrudes out through the restricted opening 54 and engages the .underface "of the bottom portion 59 of the reciprocatory member 26, thus gently forcing the upper faces 6i and side faces 6| of the teeth 21 of such reciprocatory member 26 to engage the inner faces 62 of the flanges. and the inner faces 63 of the side portion of the teeth 28 of the stationary member ll, thus effecting a frictional contact between the teeth of the reciprocatorymember and the teeth of the stationary member; be controlled by the movement or adjustment of the screw-threaded member 51. I

The ten'sioning device shown in Figs. 6 and 7,

has the same object in view and operates in the following mannen The bottom portion .82 of the stationary member I8 is provided with a slot 8.4 Within the said slot N is positioned a spring member 66. A pin 61 is placed tightly within the opening 65 and loosely within the opening 68 of the spring element 68.

The and sections 88' of the spring element 88 are provided with curved or raised portions Ii adapted to engage the under faces 12 of the .reciprocatory member .26, thus gently forcing the upper faces .6i of the teeth 21 to' engage, frictionally the inner faces, 13 of, the teeth of the stationary member [8. V

It can readily be seen that such tensioning means as herein illustrated and described will facilitate the hair cutting or shaving operation of minimize breakage possibilities and misplacement 'of parts. It will thus be seenthat the above is an important feature ofthe invention. I

If desired, the-ends of the teeth 24 may be con- Of course, such tension can or flat sides.

nected by a connecting strip I4 (Fig. 6) which may be positioned either within the concaved outer face N of the reciprocatory member 20, or be, arranged in any suitable other manner; thus minimizing breakage possibilities of the individual teeth 24. M

With respect to Figs. 8, 9, 10 and 11, the reciprocatory member 26 is provided with side wall other figures, for example, Fig 1.. or 12. The

flanges 25 are provided with flat inner faces I0 and with rounded outer faces I9, so that the skin,

ll, of the face to be shaved. may be positioned close to the cutting edges between the slots 20, by reason of the knife edges formed on the flanges 25 by the intersection of their curved and straight (Of course, the figures herein shown are exaggerated and for illustrative purposes, but in actual manufacturing the width of the slots are figured to be of suitable size for the required purposes.) vIn addition to the above advantage, such a shape will also provide sharp cutting edges 02, so that when the hair 03 enters the slots 20 and 20' it will be cut at the base portion, adjacent to the skin 6|, with'a scissorlike effect, as shown in.Fig, 11, and will not be mashed. Both teeth .sectionswilllcut' the hair with their sharp edge sections 1'! and 02 (Fig. 11)

It will be seen that when the reciprocatory member 26 will move in the direction of arrow S, the cutting sections 85 will cooperate with sections 86 in cutting hair 83, and when the reciprocatory member 26 will move towards the direction of arrow T, then the sections 01 will cooperate with the sections 80in cutting other hair 03. Thus all cutting edges are useful for the within purposes.

It may be noted that the ball bearing tensioning means, as explained above, will also facilitate the movement of the recipr'ocatory members within the stationary members, by'reducing the friction at places other than betweenthe teeth.

It may also be noted that the tensioning means may be located within either the stationary or within the reciprocatory member.

Referring to the devices illustrated in Figs. 13, 14 and 15 of the drawings, the reciprocatory or movable member. 26, is provided with an extension 93. adapted to be positioned between the inner sections'9l of the stationary member I0 and with flanges 94 adapted to slide within the slots 92, beneath the undercut sections 9| The floor I the hair to reach the inner shearing faces I02.-

length, shaped in a manner to'facilitate the entrance of hair into such hair passages. These hair passages I06 are separated by teeth I01 provided with suitable flat areas of a width greater than that of the grooves I06. The doors I 00 of the grooves I06 are inclined upwardly and inwardly to terminate in a manner providing ShOllllders I09, adapted to lift the hair and bend it into position for cutting or shaving purposes. Said shoulders are situated below the upper surface III of the teeth I01, thus providing passages for The upper surfaces III of the teeth I01 are of suitable, extended or appreciable area, flat or otherwise, and constitute a skin engaging means of the device. I

The reciprocatory member 26 is provided with the side walls H4 and a concaved or recessed bottom portion 3| of the member 26 is provided with an openingor recess 3|. means 44 is positioned through the opening 30' and within the recess 3|, as at 42, for reciprocating the member 26. The side sections of the member II are provided with loops or ears orextensions ll'which are provided with openings II" and are adapted to be secured to the handle 5 in a suitable manner, as for example, by means of screw-threaded elements 2| (Figs. 1 and 2).

The member I0 is provided .with side walls I05 which are provided at their upper and outer faces with a plurality of grooves or slots I06 forming transverse hair passages of suitable width and An actuating I section N, spacing apart the side walls Ill from each other; The side walls I I4 are provided with teeth H5, separated by slots or grooves II6. These grooves II6 are provided with shoulder portions II! and extend downwardly into the concaved section N, so as to affect the hair entering from this side in the same manner as they are affected by the grooves or slots I06' of the 'teeth'of the stationary member I8. The upper sections of the shoulders I" may meet with the upper sections of the shoulders I09, or such shoulders III may be positioned a trifle below said shoulders I09. The upper faces II8 of the teeth H5 may be even with the upper faces III of the teeth I01, but preferably positioned a trifle."

below said faces III, thus said teeth II5 will not irritate the skin of the face during shaving. The cooperating shearing edges II9 of shearing faces I 02 in conjunction with the shearing edges I2I of the shearing faces I22 are positioned in a ver'- tical plane of contact. It will be seenthat the:

cooperating, side walls I05 and Illhave common vertical planes of contact disposed substantially normal to the surface tobe shaved, and that the recessed section N permits the bulging of the skin adjacent to the shearing teeth, thus facilitating the shearing or shaving operation.

' The instruments of the present invention are assembled in the conventional manner. The reciprocatory member is arranged within the stationary member, the tensioning means arranged in the stationary member, and the top unit thus assembled is then secured in place on the handle which contains actuating means, which may include a motor or any other suitable device, and which project through the handle and the bottom of the stationary member to engage the recip- ,rocatory member to move it. It will be noted that the tensloning means are independent of the handle and will, therefore, function in the same manner in all angular positions of the top unit. I

It will also be noted that the reciprocatory member comprises a base portion which has a plurality of rows of teeth which rise erectly from, the base portion, in a manner whereby such teeth are substantially fully and firmly supported on the base portion. Such construction possesses the advantage that it prevents any distortion of' both stationary and movable teeth from excess pressure in applying the instrument against the face. The space between-the rows of teeth serves the purpose of permitting the hair to enter into the hair passages to be cut as well as allowing,

the cut hair tofall out of such hair passages, to

a permit fresh hair to enter.

From the above it will be seen that I have in- I do not, by any means, limit myself to these structures, nor to the terms used in describing the same, as they are for illustrative purposes only. Various suggestions and changes of structure or terms may be resorted to, and I desire it to be understood that I have the same in mind when showing and describing the invention, and seek protection by Letters Patent. And, although I have mentioned in describing this invention of "what material certain parts may be made, how they may be formed, shaped or styled and how they may be assembled, yet I desire it to be understood that this structure, or parts thereof,

-may 'be made of. any suitable material, and

shaped, formed, grooved or styled in any desirable manner, and assembled in any convenient way'so that the parts may be easily taken apart, removed,

cleaned, replaced and reassembled, and that various changes in detail may be-made without departing from the spirit of this invention.
