- the shaving unit L is positioned between the extensions i.
- the stationary member I8 of the said unit L is provided with depressed sections I9.
- the screw-threaded elements 2l are positioned within the nuts IB and when they are tightened the end sections of the same will engage and press against the inner flat wall of the recesses I9, as at 22, thus holding the unit L tightly in position.
- 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 Il is provided with teeth portions 24 and with flange sections 25.
- a reciprocatory or movable member 28 is slidably supported by the said stationary member IB.
- the reciprocatory member 26 is provided with the teeth portions 21 (Fig. 4).
- the upper faces of the teeth portions 21 frictionally engage the underfaces of the flange portions 25 (Fig. 11),
- the spaces or slots 28, separating the teeth 24, and the spaces or slots 28', separating the teeth 21, act as hair passages, and when, by moving the starter 3
- the slots or hair passages 28 and 2B' are of suitable length.
- the teeth are wider 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 flared or shaped cross-sectionally in a manner whereby the base or bottom portion of the 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 illuminating rays and will permit their passage about the unit to illuminate the section of the face being shaved.
- the center portion of the bottom sections 30 of the stationary member I8 and the portion 3l 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 unit, 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 5 is provided with the means to hold the mechanism for reciprocating the movable member and also for supplying energy to the illuminating means.
- a portion oi such mechanism is the actuating element.
- the usual actuating element consists of a singie arm adapted to engage the reciprocatory member for reciprocating the same.
- the mechanism in applicants structure may com prise a plurality of actuating elements, which may be in the form of a. bifurcated structure, adapted to engage a reciprocatory member at a plurality of points, or to engage a plurality of reciprocatory members, for reciprocating purposes; for example, as shown in Figs. 2, 4 and 17. This is accomplished in the following manner:
- the casing 5 (Fig.
- the upper portions 42 of the actuating element may be of enlarged. arcuate out line, such as the fan-shape shown at 46 (see dotted line indications in Fig. 1), 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 4I and secured to the element 31 or sections 33 and 39 by means of solder or friction-fit or other suitable means.
- the bar 44 may be made integral with the elements 31, as at 4B (Fig. 4), and the entire element will move as a unit to reciprocate the member 2li.

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.
- the illuminating element Il will light up and send forth the rays R, but will be extinguished instantly when the operation of the motor is stopped, for which purpose the illuminating element is provided with a suitable connection to the motor for energy supply.
- the shaving unit L may be made in various suitable styles, shapes or forms. It is naturally to be understood that the central bottom porf tions of floor sections 30 of the stationary member I8 and of the floor 3
- the actuating means 48 is in a transverse position with respect to the handle structure and is adapted to operate or reciprocate a plurality of individual shaving units.
- the end portions 45 oi' the actuating means 4B may be shaped in half* fan style, or formed in any other suitable manner adapted to retain actuating contact with the reciprocatory member 26 at any angular position of the shaving units with respect to the handle 5.
- the end portion of the screw-element 2l does not necessarily have to engage directly the end wall of the recessed section or opening I9 of the stationary member I8, but that the opening I9 may be tapered or formed in a manner whereby the end section of the screw element 2
- actuating means may be placed with respect to the handle structure, or how it may be constructed, provided the actuating means comprises a plurality of sections arranged in a manner adapted to make a plurality of contacts with the reciprocatory means for reciprocating the latter for operation purposes.
- the cutting units are shaped or arranged, as long as there is a recessed space between the individual cutting units adapted to permit the skin of the face to be shaved to bulge between such units, and the units are provided with shearing elements and hair passages at their top faces and also at their respective side faces so that, while shaving, the hair may enter simultaneously the hair passages at the top face of the leading unit and at the outer side face thereof.
- Figs. 1, 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 or spaced section between such cutting units, and such recessed spaced section is adapted to permit the skin of the face to be shaved to bulge between said units, and the hair passages being arranged in such a manner whereby the hair of the face to be shaved may enter such hair passages at the top faces of the units and also at their respective inner or outer side faces laterally to said top faces simultaneously, so that such units may be utilized.
- Fig. 17 also teaches the same novelty, namely, two individual complete shaving 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 N, and the hair of the face to be shaved entering simultaneonsly the hair passages at the top faces 2B and also the outer hair passages adjacent the arrows A and B and also the inner hair passages adjacent numeral i8. which are laterally disposed with respect to the hair passages at the top faces 25, so that such units may be utilized with greater effect and improved efficiency for simultaneous use upon the face for shaving purposes. It will therefore be seen that the structure as shown in Fig. 17 is within the spirit of the structures as shown in Figs.
- the handle may be built in a manner adapted to hold the shaving units in a fixed stationary position. If desired, however, the handle 5 may be so built as to permit the side or pivotal movement of such units.
- the units A and B may each be swung side-ways to provide the handle 5 with two side hair cutting or shaving devices which are simultaneously operable but which may be 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.
- 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 structure of the invention that the most cutting of hair takes place at each of the extreme lateral 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 connectionwith the cutting edges of the overhanging or overlapping teeth or ilanges 25, the hair that enter the laterally disposed hair passages being cut by the laterally disposed shearing edges and those entering the hair passages at the upper faces 25 being cut by the extreme end corners I or F and cleaned oil' by the center portion of the faces v25.
- each hair cutting unit has a plurality of skin engaging shearing faces, as, for example, l, 2, I, and C, D, and E. in Fig. 5, so that the user does not necessarily have to hold the instrument at any certain, particular position with respect to the face to be shaved, and may, while shaving. move the instrument in either direction 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.

- N indicates the concaved, recessed or spaced sections formed or arranged between the individual shaving units for the purpose of permitting the skin of the face to be shaved to bulge therein, both units when simultaneously applied to the skin, will tense the skin, by means of the bulge, and thereby enable the laterally disposed hair passages on each side of the spaced section to more readily pick up the hair and to present such hair to the laterally disposed shearing elements to cut it more closely to the skin.
- the edge or end portions 4 and F of the cutting unit L have been formed in a semi-circular, beveled, or curved manner (for example, as shown in Figs.
- 8 (Fig. 5) is provided with an opening 58 terminating in a restricted opening 54.
- a ball or bearing 55 is inserted within the opening 58 and is supported therein by suitable resilient means, as for example, the spring 55.
- the lower portion of the opening 58 is provided with a screw-threaded section adapted to receive a screw-threaded 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 58 of the bottom portion 50 of the reciprocatory member 25, thus gently forcing the upper faces 8
- such tension can be controlled by the movement or adjustment of the screw-threaded member 51.

Referring to the drawings (Figs. 1, 2 and 4), K indicates the assembled instrument wherein the numeral 5 shows a motor-containing handle which may be made of any desirable material (metal or plastic) and may be molded or machined to any suitable style or shape and is connected to a source of power by a cable 3, and L indicates the hair cutting or shaving unit. The top portion of the said handle 5 is provided with extensions 6, and with a recessed section 1. A light reilector, which may be in the form of a box 8, may be positioned within the recessed section 1 Members 9, adapted to receive illuminating means, such as. for example, bulb II, are positioned within the box 8. Such bulb II may be of any suitable style or shape. A transparent element I2 may cover the box 8 and may be held in place by friction t or by extensions I4 fitting or snapping over the thickened edge sections II.
In an instrument of the type shown in Fig. 17, the light reflector 8 may be positioned between the units A and B, and the illuminating means or bulb II may be held therein in the same manner and for the same purpose as in Fig. 2. Such bulb II may be held in position by friction fit within the portions 9' of elements 9 (Fig, 2A). These elements 8 are suitably insulated, in a manner readily understood and not thought necessary to be shown. and are connected to the motor (not shown) .and when the bulb I i is inserted, the side portions il' will contact elements 9 and thus close the circuit. The portions 9' willprevent displacement of such bulb I I, and when it is required to remove said bulb Il, the user may insert a suitable tool in the opening I" of the handle or casing 5, 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 II and ,gently move the tool downwardly, thus raising the bulb Il from its position. To replace the bulb Il, a gentle pressure will snap the bulb in position between the portions 9' and it will be held in place.
The extensions 6 are provided with non-circular or hexagonal nuts I6, which are held in place within the molded material by means of grooved sections I1. The shaving unit L is positioned between the extensions i. The stationary member I8 of the said unit L is provided with depressed sections I9. The screw-threaded elements 2l are positioned within the nuts IB and when they are tightened the end sections of the same will engage and press against the inner flat wall of the recesses I9, 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 Il is provided with teeth portions 24 and with flange sections 25. A reciprocatory or movable member 28 is slidably supported by the said stationary member IB. The reciprocatory member 26 is provided with the teeth portions 21 (Fig. 4). The upper faces of the teeth portions 21 frictionally engage the underfaces of the flange portions 25 (Fig. 11), The spaces or slots 28, separating the teeth 24, and the spaces or slots 28', separating the teeth 21, act as hair passages, and when, by moving the starter 3|, the actuating member 29 is put in motion, the reciprocatory member 26 will be reciprocated, the upper faces of the teeth 21 will move and pass slots 28 of the flange portions 25 and cut hair entering such slots or hair passages. The slots or hair passages 28 and 2B' are of suitable length. so as to permit the hair to enter such hair passages also laterally with respect to the top faces or flanges 25 for hair cutting or shaving purposes. 'The teeth are wider 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 flared or shaped cross-sectionally in a manner whereby the base or bottom portion of the 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 illuminating rays and will permit their passage about the unit to illuminate the section of the face being shaved. If desired, the center portion of the bottom sections 30 of the stationary member I8 and the portion 3l 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 unit, 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 5 is provided with the means to hold the mechanism for reciprocating the movable member and also for supplying energy to the illuminating means. A portion oi such mechanism is the actuating element. The usual actuating element consists of a singie arm adapted to engage the reciprocatory member for reciprocating the same. The mechanism in applicants structure, however, may com prise a plurality of actuating elements, which may be in the form of a. bifurcated structure, adapted to engage a reciprocatory member at a plurality of points, or to engage a plurality of reciprocatory members, for reciprocating purposes; for example, as shown in Figs. 2, 4 and 17. This is accomplished in the following manner: The casing 5 (Fig. 2), is provided with projections 33 and 34, adapted to support rollers 35 and 36. An element 31 is positioned between such rollers 35 and 36. The side portions 38 and 39 of the element 31 protrude through the openings 4I, and their upper end sections 42 engage the side faces 43 of the cut out portion of the reciprocatory member 25. so that when the bar 44 is put in motion, thc upper section 45 will move the element 31 and the upper end portions 42 oi the element 31 will move the reciprocatoiy member 2G, so that the teeth 21 will co-act with p the teeth 24 and with the anges portions 25 for hair cutting or shaving purposes.
If desired, the upper portions 42 of the actuating element may be of enlarged. arcuate out line, such as the fan-shape shown at 46 (see dotted line indications in Fig. 1), 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 4I and secured to the element 31 or sections 33 and 39 by means of solder or friction-fit or other suitable means.
If desired the bar 44 may be made integral with the elements 31, as at 4B (Fig. 4), and the entire element will move as a unit to reciprocate the member 2li.
The bar 44 of the actuating means may be provided with an opening 44. Screw element 5D passes through said opening 44' and is positioned within a screw threaded section 5 of the casing 5. Terminals 20 are secured to the inner section of the casing 5. Electric wires 20' are connected to the terminals 20, and when the screw element 59 is tightened, its head will engage 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. When the motor is started, the illuminating element Il will light up and send forth the rays R, but will be extinguished instantly when the operation of the motor is stopped, for which purpose the illuminating element is provided with a suitable connection to the motor for energy supply.
The shaving unit L may be made in various suitable styles, shapes or forms. It is naturally to be understood that the central bottom porf tions of floor sections 30 of the stationary member I8 and of the floor 3| of the reciprocatory member 26 do not necessarily have to be removed. In such a case the bottom portion may be provided with slots 50' (Fig. 4) and the bottom portion 3l may be provided with slots 5i which are smaller in size than the slots 50', and the upper portions 42 of the actuating means 48 engage within the smaller slots 5I and move freely within the slots 50', thus reciprocating the member 26.
With respect to Fig. 17, it will be seen that the actuating means 48 is in a transverse position with respect to the handle structure and is adapted to operate or reciprocate a plurality of individual shaving units. The end portions 45 oi' the actuating means 4B may be shaped in half* fan style, or formed in any other suitable manner adapted to retain actuating contact with the reciprocatory member 26 at any angular position of the shaving units with respect to the handle 5.
It may here be noted that the end portion of the screw-element 2l does not necessarily have to engage directly the end wall of the recessed section or opening I9 of the stationary member I8, but that the opening I9 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 I9, as at 5I' (Fig. 4) and thus hold the L unit in a stationary position.
It is really immaterial in what position the actuating means may be placed with respect to the handle structure, or how it may be constructed, provided the actuating means comprises a plurality of sections arranged in a manner adapted to make a plurality of contacts with the reciprocatory means for reciprocating the latter for operation purposes.
The same is true with respect to the plurality of individual hair cutting or shaving units, as
taught by applicant. It does not matter how the cutting units are shaped or arranged, as long as there is a recessed space between the individual cutting units adapted to permit the skin of the face to be shaved to bulge between such units, and the units are provided with shearing elements and hair passages at their top faces and also at their respective side faces so that, while shaving, the hair may enter simultaneously the hair passages at the top face of the leading unit and at the outer side face thereof. laterally to said top face, and also the hair passages at the top face of the trailing unit and at the inner side face thereof, laterally to such top face, thereby providing an enlarged shearing-area contact between the units and the skin to be shaved, thus enabling such units to be utilized with greater effect and improved efliciency for simultaneous use upon the face for shaving purposes, it would naturally come within the spirit of applicant's invention.
For example, Figs. 1, 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 or spaced section between such cutting units, and such recessed spaced section is adapted to permit the skin of the face to be shaved to bulge between said units, and the hair passages being arranged in such a manner whereby the hair of the face to be shaved may enter such hair passages at the top faces of the units and also at their respective inner or outer side faces laterally to said top faces simultaneously, so that such units may be utilized.
simultaneously upon the face for shaving purposes. Fig. 17 also teaches the same novelty, namely, two individual complete shaving 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 N, and the hair of the face to be shaved entering simultaneonsly the hair passages at the top faces 2B and also the outer hair passages adjacent the arrows A and B and also the inner hair passages adjacent numeral i8. which are laterally disposed with respect to the hair passages at the top faces 25, so that such units may be utilized with greater effect and improved efficiency for simultaneous use upon the face for shaving purposes. It will therefore be seen that the structure as shown in Fig. 17 is within the spirit of the structures as shown in Figs. 1, 5, 6, 8, 13 and 15. It is, therefore, evident that it is immaterial how the individual shaving units are constructed, but that it is the concept of arranging such units, and the performance of same, particularly the practicability of such arrangement, that matters. It will, therefore. be clearly seen that all of the above figures, namely Figs. 1, 5, 6, 8,17, 13 and 15 are within the spirit and scope of the same invention.
The handle may be built in a manner adapted to hold the shaving units in a fixed stationary position. If desired, however, the handle 5 may be so built as to permit the side or pivotal movement of such units. When such pivoting provision is made in the handle for a device such as shown in Fig. 17, the units A and B may each be swung side-ways to provide the handle 5 with two side hair cutting or shaving devices which are simultaneously operable but which may be 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. 17, are adjusted in an upright, stationary position, the user will be provided 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 structure of the invention that the most cutting of hair takes place at each of the extreme lateral 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 connectionwith the cutting edges of the overhanging or overlapping teeth or ilanges 25, the hair that enter the laterally disposed hair passages being cut by the laterally disposed shearing edges and those entering the hair passages at the upper faces 25 being cut by the extreme end corners I or F and cleaned oil' by the center portion of the faces v25. It will therefore be seen that by providing eight of such shearing corners, and laterally disposed side shearing faces, and top shearing faces, all operable simultaneously, particularly when the devices A and B are both adjusted in upright position on the handle, an enlarged shearing-area is provided for engaging the skin to be shaved, thereby providing a maximum of effectiveness for shaving or hair cutting purposes. It can thus be plainly seen that applicants invention is a practical and useful structure. The figures herein shown are for illustrative purposes only; and various changes in detail of structure or in the arrangements of parts or of the units may, of course, be resorted to without departing from the spirit and scope of the invention.
It will be seen that each hair cutting unit has a plurality of skin engaging shearing faces, as, for example, l, 2, I, and C, D, and E. in Fig. 5, so that the user does not necessarily have to hold the instrument at any certain, particular position with respect to the face to be shaved, and may, while shaving. move the instrument in either direction 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 shown in Figs. 1,
'I'he letter N indicates the concaved, recessed or spaced sections formed or arranged between the individual shaving units for the purpose of permitting the skin of the face to be shaved to bulge therein, both units when simultaneously applied to the skin, will tense the skin, by means of the bulge, and thereby enable the laterally disposed hair passages on each side of the spaced section to more readily pick up the hair and to present such hair to the laterally disposed shearing elements to cut it more closely to the skin. It will be seen that the edge or end portions 4 and F of the cutting unit L have been formed in a semi-circular, beveled, or curved manner (for example, as shown in Figs. 1 and 17) so that such edge or end portions, when pressed against the face to be shaved, will not injure the skin thereof, but will cause such skin to form bow-waves in front of the moving units, in a manner whereby the hair will be so positioned that they may enter the hair passages laterally with respect to the top faces of such units, and be cut by the side shearing faces adjacent to the end portions 4 or F before actually reaching the immediate shearing sections of the top faces, thus facilitating the shearing operation of the shaving units.
The bottom portions 52 of the stationary member |8 (Fig. 5) is provided with an opening 58 terminating in a restricted opening 54. A ball or bearing 55 is inserted within the opening 58 and is supported therein by suitable resilient means, as for example, the spring 55. The lower portion of the opening 58 is provided with a screw-threaded section adapted to receive a screw-threaded 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 58 of the bottom portion 50 of the reciprocatory member 25, thus gently forcing the upper faces 8| and side faces 6|' of the teeth 21 of such reciprocatory member 25 to engage the inner faces 82 of the flanges 25 and the inner faces 83 of the side portion of the teeth 28 of the stationary member I8, thus effecting a frictional contact between the teeth of the reciprocatory member and the teeth of the stationary member. Of course. such tension can be controlled by the movement or adjustment of the screw-threaded member 51.
The tensioning device shown in Figs. 6 and '1, has the same object in view and operates in the following manner. The bottom portion 52 of the stationary mem-ber i8 is provided with a slot 64 and with an opening 85. Within the said slot 54 is positioned a spring member 86. A pin 61 is placed tightly within the opening 55 and loosely within the opening 6B of the spring element 66. The end sections 69 of the spring element 9B are provided with curved or raised portions 1| adapted to engage the under faces 12 of the reciprocatory member 2B, thus gently forcing the upper faces 6| of the teeth 21 to engage frictionally the inner faces 13 of the teeth 24 of the stationary member IB.
It can readily be seen that such tensioning means as herein illustrated and described will tioned close to the cutting edges between the facilitate the hair cutting or shaving operation a of the instrument. It will also hold the stationary member and the reciprocatory member in a united form, a matter which is of great importance to manufacturer and merchant, as it will minimize the possibility of breakage and misplacement of parts. It will thus be seen that the above is an important feature of the invention.
If desired, the ends of the teeth 24 may be connected by a connecting strip 14 (Fig. 6) which may be positioned either within the concaved outer face N of the reciprocatory member 28, or be arranged in any other suitable manner, thus minimizing the possibility of breakage of the individual teeth 24.
With respect to Figs. 8, 9, 10 and 11, the reciprocatory member 26 is provided with side wall sections 15. These sections are drilled at suitable places, forming holes or openings 19. 'I'he top portion above said openings 19 is then removed or milled off until undercut edges 11 are formed, thus providing cutting teeth defined by slots 29, by reason of the knife edges formed on the flanges 25 by the intersection of their curved and straight or fiat sides. (Of course, the gures 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.) In addition to the above advantage, such a shape will also provide sharp cutting edges 82, so that when the hair 08 enters the slots 28 and 28' it will be cut at the base portion, adjacent to the skin 8|, with a scissor-like effect, as shown in Fig. 11, and will not be mashed. Both teeth sections will cut the hair with their sharp edge sections 11 and 82 (Fig. 1l). It will be seen that when the reciprocatory member 28 will move in the direction of arrow S, the cutting sections B5 will cooperate with sections 05 in cutting hair 83, and when the reciprocatory member 28 will move towards the direction of arrow T, then the sections 81 will cooperate with the sections 88 in cutting other hair 88. 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 reciprocatory members within the stationary members, by reducing the friction at places other than between the 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 9| of the stationary member I8 and with flanges 94 adapted to slide within the slots 92, beneath the undercut sections 9|. The floor or bottom portion 30 of member |8 is provided with an opening 30' and the under face of the bottom portion 3| of the member 26 is provided with an opening or recess 3|'. An actuating means 44 is positioned through the opening 30' and within the recess 3|', as at 42, for reciprocating the member 25. The side sections of the member |0 are provided with loops or ears or extensions IB' which are provided with openings |8" 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 i8 is provided with side walls |05 which are provided at their upper faces and outer and inner side faces with a plurality of transversely cut grooves or slots |06 forming laterally enterable transverse hair passages of suitable width and length, shaped in a manner to facilitate the entrance of hair laterally into such hair passages. These hair passages |06 are separated by teeth |01 provided with suitable flat areas of a width greater than that of the grooves |06. The floors |08 of the grooves |05 are inclined upwardly and inwardly to terminate in a manner providing shoulders |09, adapted to lift the hair and bend it into position for cutting or shaving purposes. Said shoulders are situated below the upper surface I of the teeth I01,.thus
providing passages for the hair to reach the inner shearing faces IIII. The upper surfaces II I of the teeth IIII are of suitable, extended'or appreciable area, fiat or otherwise, and constitute a skin engaging means of the device.
The reclprocatory member 28 is provided with the side walls III and a concaved or recessed section N, spacing apart the side walls Ill from each other. nie side walls I I4 are provided with teeth III, separated -by slots or grooves IIB forming laterally enterable transverse hair passages. These grooves or hair passages IIB are positioned laterally with respect to the upper faces of the teeth Ill and are provided with shoulder portions III and extend downwardly into the concaved section N, so as to permit the hair to enter from such concaved side section into the laterally disposed hair passages and b e affected in the same manner as they are affected by the grooves, slots or hair passages |06 of the teeth of the stationary member I8. The upper sections of the shoulders III may meet with the upper sections of the shoulders |09, or such shoulders II'I may be positioned a trifle below said shoulders Ill. The upper faces IIB of the teeth III may be even with the upper faces III of the teeth Ill, .but preferably positioned a trifle below said faces III, thus said teeth IIE will not irritate the skin of the face during shaving. The cooperating shearing edges IIB of shearing faces Il! in conjunction with the shearing edges III of the shearing faces |22 are positioned in a vertical plane oi' contact. It will be seen that the cooperating side walls IBS and III have common vertical planes of contact disposed substsntially normal to the surface to be shaved, and that the recessed section N permits the bulging of the skin adjacent to the shearing teeth, and that in the embodiments of the invention as shown, for example, in Figs. 1, 5, 6, l'i and 13, there are one or more shaving planes which are disposed at an angle, oblique or right, to the plane tangent to the top of the shaving device or perpendicular to the longitudinal axis of the device permitting the cutting of hair laterally of the top of the shaving device, 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 adjustable tensioning means arranged in the stationary member, and the top unit thus assembled is then secured in place on the handle which may contain a motor or any other suitable device provided with actuating means which may project through the handle and the bottom of the stationary member to engage the reciprocatory member to move it. It will be noted that the tensioning means are independent of the handle and will, therefore, function in the same manner in all angular positions of the top unit.
It will also be noted that the reciprocatory member comprises a base portion which has a plurality oi rows of teeth separated by hair passages formed fully transversely of such member, said teeth rise erectly from the base portion in a manner whereby they are substantially fully and rmly supported on such base portion. Such construction possesses the advantage that it prevents any distortion o! both stationary and movable teeth from excess pressure in applying the instrument against the face. The space N between the rows of teeth serves the purpose of permitting the hair to enter laterally into the hair passages III, from the side of such spaced section N, to be cut by the adjacent teeth and also allowing the cut hair to fall out of such hair passages, to permit fresh hair to enter.
From the above it will be seen that I have invented and perfected a device of new and unique design, a device which is practical, useful and, therefore, of commercial value, and although I have shown certain preferred forms or illustrations in order to explain and describe the novelty vof my invention, yet, by showing such structures, 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 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.
