(Yitzhak Sadeh St. 88, Tel-Aviv, Israel) Filed Aug. 14, 1963, Ser. No. 302,066 3 Claims. (CI. 30-43) This invention relates to the construction of individually assembled shearing sections in general, and more particularly so to a type of shearing section used in connection with electric razors or dry shavers.

A primary object of this invention is to provide a completely individually-assembled shearing section comprising a carrier and a shaving unit and a separate base element and an expandable coil-spring structure, wherein such shaving unit consisting of an outer cutter member having a shear-face and a floor portion provided with an opening and carrying a cooperative movable cutter member having a shear-face, and wherein the outer cutter member is carried by the base element and is movable thereon transversely relative to such base element and simultaneously therewith such outer cutter member is prevented from moving longitudinally of the base element, and wherein such coil-spring is carried by the base element in a manner having its upper portion placed through the opening in the floor of the outer cutter member for engagement with the movable cutter member for urging the shear faces of the two cutter members into frictional engagement with each other for shaving purposes simultaneously therewith such coil-spring providing tensioning means for urging the shaving unit into transverse movements for automatic adjustment or tilting of the shear faces during shaving operation, and wherein such assembled shearing section is positionable upon the handle section and/or removable therefrom as an independently assembled shearing section. The above and other objects of my invention are attained by a novel construction which will be hereinafter described and illustrated in the drawing in connection with a specific embodiment of the invention. 7

I am showing the several figures or views by way of ex ample for illustrative purposes and for a better and clearer understanding of my invention, and not for limitation purposes.

The size of the parts shown in the drawings herein, and the spacing therebetween, being exaggerated for clarification purposes.

The outer cutter member, indicated by arrow 4, comprises a lower section 7 having side wall sections 8 and a floor portion 8' provide-d with an open space 8"; and also with an upper section 9 having a shear-face 11 and side wall portions 12 which are secured to the wall sections 8 by suitable means, for example, electric spot welding or the kind, uniting same into a unitary structure.

Arrow 5 indicates the inner cutter member for being positioned within the outer cutter member to cooperate therewith for shaving purposes. The inner cutter member comprises an upper section 15 having a shear-face 16 and side wall sections 17; and also having a lower section 18 provided with wall portions 19 and with a floor section 21. The wall portions 19 are secured to the wall sections 17 in a manner as are the

walls

8 and 12 above mentioned. The floor section 21 is provided with two spaced apart channeled sections 22 and with recessed, grooved, or slotted portions 24, and with an opening 25 for housing therein a portion of an actuating element 26 for operable shaving purposes (FIG. 7).

The base member or element (indicated by arrow 6) comprises a channeled structure having spaced wall sections 31 each provided with recessed portions or openings 32, and with a floor portion 33 having an opening 34 provided with side portions 35 each having a flange section 36. The end portions 37 and 37', of the floor portion 33, are each provided with suitably-shaped flange sections or

extensions

38 and 38, each of these

extensions

38 and 38 are provided with a bead or depressed portion 2 (FIG. 9) for a purpose which will be hereinafter explained.

Arrow 41 indicates a coil-spring in an expanded position, of suitable longitudinal shape cross-sectionally, provided with a lower coil or ring 42 and with an upper coil or ring 42'.

My cushioning shearing section may be assembled in the following manner:

The coil-spring (arrow 41) is positioned upon the floor 33 of the base element (arrow 6), the lower coil or ring 42 is moved in a slidable manner upon the side portions 35 (FIG. 4) underneath the flange portions 36 until the front portion 43, of the coil-ring 42, becomes located upon the portion 37 of the floor 33 and the rear portion 43' becomes located upon the portion 37, and the side portions 44 of the ring 42 are each located upon one of the side portions 35 of the floor 33. The flange portions 36 are yieldable to a desired degree so as to-permit the slidable movement of the coil or ring 42 and then hold the spring 41 in a desired upright position.

My cushioning shearing section may be assembled in the following manner:

The cutter member indicated by arrow 5 may be posi tioned within the cutter member indicated by arrow 4, having its shear-face 16 underyling the shear-face 11, thus forming an operable shaving unit (as indicated by arrow 19 FIG. Such unit is then placed in a downward manner into the base element indicated by arrow 6 FIG. 3, in a manner whereby the upper portion of the coil-spring 41 may pass through the opening 8" of the floor of the outer cutter member arrow 4, for having its upper coil ring engaging the inner cutter member arrow 5, wherein the upper coil or ring 42 may nest itself within the channeled sections 22 and within the recessed portions 24.

The side wall portions 31, of the base element arrow 6, are flexible to a degree whereby such wall portions 31 may be spread outwardly to an extent permitting the insertion of the outer cutter member 4 therebewteen; during such insertion the outer cutter member 4 is urged downwardly until each of the outwardly disposed portions 14 snap into openings 32 (FIG. 8) of the wall portions 31; such portions 14 are adapted to move within such openings 32 in a manner whereby the shaving unit may move transversely relative to the floor portion 33, of such base element 6, (see FIG. 10). These portions 14 are adapted during upward movement to engage the upper end portion 14', of the opening arrow 32, (FIG. 8) holding the shaving unit in position upon the base element 6, preventing accidental removal therefrom and also to prevent longitudinal movements of such shaving unit relative to its base element.

From the above it is clear, that when my shearing section is fully assembled, the coil-spring 41 will be held firmly in position upon the base element 6, having its upper coil or ring 42' engaging portions of the floor 21 of the inner cutter member 5, urging same upwardly for having its shear-face 16 into frictional engagement with the shear-face 11 of the outer cutter member 4 for shaving purposes, and simultaneously therewith such coilspring 41 will provide resilient means for urging such shaving unit into transverse movements during shaving operation, enabling such spring 41 to become automatically expandable and also compressible to enable the shear-face of the shaving unit to tilt or move to adjust itself during shaving operation transversely relative the base section 6 (see FIG. 10).

The movements of the inner cutter member 5 during shaving operation will cause the coil-spring 41 to vibrate and thus shake sheared hair off its coils.

While shaving the coil-spring 41, which is in normal expanded position, may become automatically compressed and/or expanded to desired degrees for supporting the shaving unit in its tiltable or retractable movements thereby facilitating such shaving operation.

Thus, my invention as disclosed herein, comprises a fully completely-assembled individual shearing section for a shaving implement. Such shearing section may comprise (as may be required) a single shaving unit or a plurality of individually assembled shaving units, and be made in various shapes, styles, or forms; the disclosures herein are for illustrative purposes only and not for limitation purposes.

My present assembled shearing section comprises, as above pointed out, a shaving unit consisting of an outer cutter member 4 having an inner cooperative cutter member 5, and a base element 6 housing the shaving unit, and a coil-spring structure 41 carried by the floor portion 33 of the base element 6 for engaging the inner cutter member of the shaving unit to cause frictional engagement between the shear-faces thereof, and simultaneously therewith such spring structure is providing tensioning means for supporting such shaving unit during its transverse tiltable or retractable movements while shaving.

The fact that the coil-spring 41 is positioned loosely Within the opening 8" in the floor 8 of the outer cutter member 4, and is able to utilize freely the full space between the floor 33 of the base element 6 and the underface 21 of the inner cutter member 5, will greatly reduce resilient strain of such coil-spring 41 and case its movements thus facilitating its operational action.

Such as assembled shaving unit is a practical and useful structure. It can be utilized as a unitary shaving unit, secured to the handle and/ or removed therefrom as such unitary shaving unit, and is marketable as an assembled shaving unit.

In FIG. 7, I am showing a longitudinal cross-sectional view of one of my shaving unit (secured to my carrier arrow C), disclosing the coil-spring 41 being in normal expanded position, urging the shear-faces 11 and 16 into frictional engagement with each other, and simultaneously therewith supporting the shaving unit in its upward position for shaving purpose. And in FIG. 10 I am showing a cross-sectional view of two of my shaving units carried by one carrier, wherein one of such shaving units being in a position similar to that shown in FIG. 7 (see arrow U), and the other of my shaving units being in a retracted position (see dotted lines 19"), movable transversely relative to the floor portion of the carrier or that of the handle seat. It is thus clear that one or more of my shaving units may be utilized simultaneously for shaving purposes, being removable and/or replaceable as individually-assembled shaving units.

My carrier comprises a suitably shaped structure for example as indicated by arrow C (FIG. 6), wherein the floor portion of such carrier is provided with an open section 51' having side portions 51 and side flange sections 52 and 52' and wall portions 53; the flange sections 52 and 52' are each provided with depressed or bead portions 3, for a purpose which will be hereinafter explained.

The base element indicated by the arrow 6 (FIG. 3) may be secured to the carrier arrow C in any suitable manner for example, the flange portion 52 may be positioned between the flange portion 38 and the floor portions 39 (see FIG. 9), and the flange portion 52' may be positioned between the flange portion 38' and the floor portions 39' (see FIG. 3), and then by moving the shearing section slidably into position upon the carrier the snap fastener 2 of the flange 38, or 38 (FIG. 9), will become interlocked with the snap fastener 3 of the flange portions 52 and 52' (FIG. 6), thus holding the shearing section in desired position upon the carrier C.

The walls 53 of the carrier C are each provided with a curved end portion 54 (FIG. 7) terminating into an inclined section 63 adapted to fit or snap into the recessed portion 64 of the handle-casing 56, thus holding the shearing section upon such handle-casing for shaving purposes.

The handlecasing 56 is provided with a recessed section 61 forming a seat for the assembled shearing structure, this recessed section 61 is provided with a non-punctured floor having wall portions 62, and also having an upwardly extending section or boss structure 67 (FIGS. 7 and 11); this boss structure 67 is provided with a through opening 66 for housing therein an actuating element 26 to engage and operate the inner movable cutter member for shaving purposes. The element 26 is provided with a recessed shouldered portion 69 (FIG. 11) to support therein a resilient cover or collar 68 adapted to cover the boss opening 66, and simultaneously therewith to shift sheared hair away therefrom thus preventing the access of sheared matter into the motor compartment (not shown).

The above has been explained by way of example only and not for limitation purposes. Various other suitable means may be utilized to bring about or perform the functions or accomplishment as herein above pointed out and explained.

From the above it is evident, that my present invention teaches an entirely new form of structure in the art of making assembled shearing sections for use in connection with electrically operated shaving implements; a structure which is unique in its ability to reciprocatedly adjust itself to the position of the face being shaved and to co-operate therewith for engaging every curvature thereof for clean shaving; and wherein the spring member will actually cooperate with the operable action of the inner movable cutter member; and although I have shown certain preferred forms or illustrations in order to explain and describe the novelty of my invention, yet, by showing such structure, I do not, by any means, limit myself to these structures, nor to the terms used in describing same, as they are for illustrative purposes only. Various suggestions and changes of structure may be resorted to. And although I mentioned 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 part thereof, may be made of any suitable material, and shaped, formed. styled or arranged in any desirable manner, and assembled in any suitable and convenient way so that the parts may be easily taken apart, removed, cleaned, replaced and reassembled, and that various changes in shape and in detail may be resorted to without departing from the spirit of this invention.
