  • the set position of the cutter head in the casing substantially ush with the exterior walls or other appurtenances of the casingdoes not provide for comfortable and effective positions for all shaving conditions, as for example, in accommodating hairsv of different lengths and varying coarseness. Further, the set position of the cutter head interferes with the use of the cutter head for trimming sideburns and mustaches.
  • Another object is to provide a novel electric dry shaver wherein novel means are provided for adjusting the posi- Ition of the cutter head in the casing to selected elevated operative positions forl accommodating all shaving conditions.
  • a further object is to provide novel means for gaining -access to a cutter head for cleaning or servicing without removing the cutter head from the casing or removing protective casing structure therefrom.
  • Another object is to provide novel end ap means for protecting a cutter head and which means includes means for automatically releasing the end flaps to an open condition when access to the cutter head is desired.
  • the present invention contemplates an electric shaver of novel construction.
  • the electric shaver comprises an outer sleeve casing in which is disposed an inner casing supported for movement between spaced limit positions within the outer casing.
  • a cutter head is mounted on one end of the inner casing and in a first limit position of the inner casing the cutting surface of the cutter head is exposed at one end of the outer casing substantially flush with the exterior walls thereof.
  • Actu-ating means are provided which are operable to effect and control movement of the inner casing to the other limit position in a direction outwardly of the outer casing whereby the cutting surface of the cutter head is raised above the walls of the outer casing to selected elevated positions intermediate the limit positions.
  • protective end flaps are provided at release the end flaps to open condition upon arrival of the inner casing at the other limit position whereat the cutter head is fully exposed for cleaning.
  • FIG. 1 is a perspective view of an electric dry shaver in which is incorporated the present invention and illustratesthe cutter head thereof at the lower limit position;
  • FIG'. 2 is a sectional view taken on the line 2 2 of FIG. 3;
  • FIG. 3 is a fragmentary partly cross sectional elevational view of the electric shaver of FIG. 1 with the cutter head and inner casing in upper limit position;
  • FIG. 4 is a sectional view taken on the line 4 4 of FIG. 3;
  • FIG. 6 is a fragmentary front elevational View of the actuatingmeansV under conditions where the cutter head is at the'position shown in FIG. 1;
  • Electric shaver 10 (FIG. 2) v includes an outer vsleeve or enclosure casing 11 open at each end thereof and having spaced sidewalls 12 and 13 respectively and spaced endwalls 14.
  • An inner casing 15 (FIGS, 2, 3, 4 and 7) is disposed within outer sleeve casing 11 and is mounted for movement therein between spaced limit positions in a mannerr to be hereinafter fully described.
  • An end portion spring 58 is press-fitted in a slot 61 at one end of recess 59 to prevent accidental dislodgement of spring 58 from casing 11.
  • a detent portion 62 is provided intermediate the ends of spring 58 and which detent portion 62 projects upwardly into aperture 49 in sidewall 12 and which detent 62 is adapted toeugage in a selected one of a pluralityof stop notches in hub 48 ⁇ of 4button ⁇ 46 in accordance withthe selected position of finger piece 47 on outer casing 11.
  • the stop notches are designated a, b, c, d, e and f respectively in FIG. 6 and which designations correspond to-stop positions A to F inclusive (FIG.
  • Button 46 is mounted on casing 11 in aperture 49 by aligninga pair of ear projections 63 (FIG. 6) which are formed on hub 48 with a pair of slots.64 provided in the surface of sidewall 11 about the periphery of aperture 49. Hub 48 is then inserted into aperture 49.
  • An oversized notch designated x in FIG. 6 is provided in the hub 48 and is adapted to pass over detent 62 in the aligned positionofears63 with slots 64 as hub 48 is 'moved into aperture 49.
  • a slight rotation of a finger piece portion 47 of button 46 places ear projections 63 against the rear surface of-sidewall 12 to thereby lock button 46 to outer casing'll for rotation in aperture 49.
  • An end ap mechanism 65 (FIGS. 3 and 7) is provided for protecting the ends of cutter head 25 and which mechani-sm 65 includes a cover plate 66 (FIG. 7) having spaced downwardly depending resilient side iianges 67 and end anges 68 clamped to the spaced upper edge portions of inner casing sidewalls 17418 and endwalls 19 respectively.
  • Resilient latch fingers 69 extend upwardly from opposite ends of cover plate 66 and are adapted to engage portions (not shown) of cutter head mounting plate 28 in a known manner to detachably mount cutter head 25 to top wall 2U-of inner casing 15.
  • Spaced end flaps 70 and 71 are disposed at opposite ends of cover plate 66 and are hinged thereto by a pair of trunnion-pins 72 formed on the lower opposite corners of each tiap 70-71 and which pins 72 are disposed in apertures provided in spaced upstanding ear portion-s 73 of cover plate 66.
  • Means are provided -to normally'maintain aps 70-71 against the ends of cutter head 25 (FIG. 5) to protect the end portions thereto from damage and which means include a ⁇ plate ⁇ memberf 75 (FIGS. 3, 5 and 7) disposed intermediate cover plate 66 and top wall 20 of inner casing 15. Plate member 75 is provided with resilient side flanges 76 (FIG.
  • buttons 46 continue rotation of button 46 causes projection 55 to pass over line H-H and move to the right in slot 56 as it drives casing upwardly in outer casing 11.
  • lugs 82 on protective end flaps 70 and 71 are brought into engagement with the protruding edges 14a of endwalls 14 of outer casing 11. Further upward movement of inner casing 15 causes edges 14a to drive lugs 82 downwardly to pivot flaps 70 and 71 on pins 72 in the direction designated by the arrows C in FIG. 5.
  • button 46 may be rotated clockwise from the position shown in FIG. 3 to the position of FIG. 1 to lower casing 16. If button 46 is rotated clockwise (FIG. 3) projection 55 moves to the right in slot 56 (FIG. 3) and commences to drive inner casing 15 downwardly projection 55 passes over center line H-H at the right of center K of button 46 (FIG. 3) itis located approximately at the right end of slot 56.
  • cutter head 25 may be moved by an operator and maintained at any selected elevated intermediate positions B, C, D and E intermediate the limit positions A and F.
  • cutter head 25 projects above endwalls 14 and combs 37 of outer casing 11 for providing selected positions for various trimming and shaving operations.
  • detent 62 will be positioned in the stop notch on hub 48 corresponding to the selected position of cutter head 25 to hold inner casing 15 and cutter head 25 in the selected adjusted position.
  • end flaps 70 ⁇ and 71 are maintained in closed condition to protect the opposite end portions of cutter head 25 which at these positions project above outer casing 11.
  • the novel electric dry shaver has many advantages in use.
  • One advantage is that the cutter head may be readily positioned at predetermined elevated positions to provide 6 selected positions of cutter head 25 for shaving and trimming operations according to the comforts and needs of the operator.
  • the novel means for adjusting the position of cutter head 25 in the shaver provides for ready access thereto for cleaning without removing the same from the shaver.
