  • the present invention provides a construction of shaver in which the distance between the combing roller and the adjacent edge of the cutter element may be set in a predetermined relation by manual operation of an adjusting device so that the user may set the combing rollers in advance for use with beards of different characteristics and can readjust the setting at will.
  • the combing roller on one side may be adjusted for use with one type of beard and the roller on the other side may be adjusted for another type of beard if so desired.
  • the invention provides a shaver construction which will permit the combing rollers to be inserted and removed at will as before, while at the Same time being adjustable in a predetermined manner as above set forth.
  • the invention provides a shaver casing with a movable portion in the form of a frame which is vertically movable and detachably mounts the combing rollers.
  • Manipulable means is associated with the frame to effect the vertical movement of the frame to predetermined vertical positions whereby the adjacency of the combing rollers to the adjacent edge of the cutter element may be varied as desired. Itis also contemplated to provide suitable indicating means in as- Sociation with the manipulable means whereby certain desirable positions of the combing rollers may be visually observable.
  • FIG. l is a front elevation, partly broken away' of the upper end of the shaver casing, showing the combs in the lowest position;
  • FIG. 2 is a vertical longitudinal section taken on the line 2 2 of FIG. 4, showing the combs in the highest position;

  • This frame plate 2d is provided at its ends with upstanding ears 23 as integral extensions of the flanges 21. These ear-s 23 are provided with apertures 25 to receive the ends of combing rollers 2d.
  • the combing roller is corrugated land is hollow.
  • a slidable pin 26 projecting therefrom and backed by a spring 27.
  • the outer end of the pin is reduced in diameter as at 28 and the end of the roller is crimpled inwardly a little as at 29 to limit the outward movement of the pin 26.
  • the end of the pin 26 projects into the aperture 25 in the ear 23 and has an upstanding circular rib 3) formed thereon close to the end to limit the projection of the end of the pin into the aperture.
  • the reduced end 28 of pin 26 has end wall portion 23 on the outer face of rib 30 engaging the end wall at theinner end of aperture 25 formed by ear 23 in limiting movement of reduced end 2S in the aperture.
  • rollers 31 disposed across the top of the casing between the corrugated rollers and between the cutter head sections, as shown in FIGS. 4a and 4b. These rollers are of smooth surface but otherwise the same as the rollers 24 and their ends are projected into suitable apertures in the upper portion 18 of the end walls 15 and 16, as seen in FIG. 1.
  • the invention provides mechanism whereby the frame plate or supporting member 2@ supporting the combing rollers 24 may be manually adjusted and set on the casing to position the rollers at varying distances with respect to the adjacent edges of the cutter head and skin engaging face thereon. This is desired to facilitate the cutting of varying types of light, medium, and heavy beards.
  • frame plate 20 is provided with a central rectangular opening 32 at opposite sides of which are located inclined slots 33.
  • the walls 14 of upper casing 12 are provided with elongate central openings 34 and slots 35 disposed beyond opposite ends of openings 34. These openings 34 are alined with openings 32 in frame plate 20 and openings 35 are alined or positioned to register with inclined siots 33 in frame plate Z0, as clearly seen in FIG. 6.
  • a manipulable element such as the operating members or slide plates 36'one disposed against the outer face of each of the side walls 14 of the upper casing portion 12.
  • the slide plate 36 is provided on the inner upper side portion with an inwardly projecting T-shaped tongue 37 centrally disposed thereon and inwardly projecting pins 38 at opposite sides of the tongue l 2,991,554 l W i A" A j 37.
  • the tongue 37 is in line with the openings 32 and 34 and the pins 38 are respectively in line with the openings 35 and the slots 33.
  • a latch or spring plate 39 which has a central rectangular opening 40 and elongate openings 4l on opposite sides ci the opening 40.
  • the spring plate 39 is normally held in curved relation under tension against plate 20, as shown in FIG. 6, and its ends 42 are reversely curved to provide substantially a line Contact with the back of plate 2% when the spring and the plate are placed together in tensioned relation, as shown in FIG. 5.
  • the spring plate 39 is provided with oiiset lips 43 formed from the upper side portions adjacent opening 49 and are offset toward the adjacent surface of plate 20.
  • the spring When the spring is in assembled relation it is slightly curved with opposite ends offset laterally with respect to their unstressed positions thus creating in the spring a tension which tends to hold plates 29 and 36 in close slidable engagement with the side wall of the casing.
  • the spring plate 39 In order to apply the spring plate 39, with the slide plate 36 and the frame plate Zi in the relative position on the walls of the casing as shown in FIG.
  • the head of the tongue 37 extends slightly beyond the inner face of the frame plate Ztl, and with the parts in this position, the spring plate 39 is pressed against the back of the frame plate 2t) with the lips 43 initially disposed above the head of the tongue and then the spring plate 39 is forced down so that the lips lie back of the head of the tongue 37. While this is being done the ends of the spring plate are held sprung back to pass down across the ends of the pins 3S and when the lips are in proper place the ends of the spring are allowed to move forward against the back of the frame plate or supporting member 20 and the pins 38 will enter the openings 41. Because of the tension in the spring plate 39 the parts are held in close relationship and therefore the slide plate 36 can be moved across the face of the casing wall with enough friction to keep it in any desired adjusted position.
  • the plate 36 is provided with spaced apertures 44 and the walls of the casing are provided with small thin blocks on the surface of which are disposed indicia 46. These are arranged in a slanting relation so that when the lowest of the indicia is seen through apertures 44, the combing rollers are in their lowest position and so on thus giving an instant indication of the position of the rollers. By thus sliding the slide plate across the face of the casing wall the desired position of the combing rollers is eiiected and clearly indicated.
  • the slide plate is moved horizontally back and forth across the casing as illustrated in FIG. l in adjusting the position of roller 3l.
