  • the shaving machine illustrated in Figure 1 comprises a hollow handle formed from opposite halves I and 2 within which there is located a motor (not shown) whose armature shaft is indicated by the numeral 3.
  • An electric cord 4 is provided for connecting the motor to a source of current supply.
  • the motor is provided with a manually operable starting wheel 5 and the armature shaft 3 is formed at its outer end with an eccentric pin 6, received in a slot I formed in the movable cutter 8 of the device.
  • the movable cutter is slidably mounted in a hollow guideway or guard member H).
  • notches. II are formed by way of which hair is freely admitted to the shearing edges of the device.
  • the guard member is formed from two parts which are hinged together along one edge as at l2, and opposite thereto, depending lips l3 are provided for receiving threaded adjusting members I4 which cooperate with a spring l5 interposed between the lips l3 of the guard member to effect the adjustment of the end facesof the guard member toward and away from the end portions of the cutter 8.
  • the opposite edges of the ends of the movable cutter in contact with the guard member are formed with sharply pointed teeth I6 which cooperate withthe edges of the notches H at the inner ends thereof, and during the operation of the device they serve to shear off hair projecting through such notches.
  • the single-headed device shown in Figures 3, 6 and 7 operates in substantially the same manner as the device shown in Figure 1 and it comprises a combined hollow motor. casing and handle formed from mating halves I1 and I8, at one end of which there is removably held a single shaving head which comprises a hollow guideway or guard member 20 within which a movable, toothed cutter 2

  • the manually operable starting wheel 26 of this device projects from one side only of the handle of the device in a position where it may be readily manipulated by the thumb of the user.
  • the cutter head and the method of its securement to the handle is illustrated in detail in
  • the threaded members 22 are each centrally bored for reception of a spring 21 provided for urging rockable pins 28 into contact with notches 30, one of which is formed adjacent to each end of the cutter, and in this manner, the guard member is detachably secured to the handle of the device by means of the threaded members 22 and the cutter is urged into contact with the rear face of such guard member by means of the pins 28 and their springs 21.
  • the guard member 20 is cut away at 3
  • the series of notches formed at the edges of the single and double-headed guard members define openings which are widest at their midpoints and which taper as their ends are approached.
  • a rotary cutter with a series of disk-like cutters thereon may be used to produce without difliculty, cutter heads having as many as twenty-five slots to the inch on the opposite edges of the guard member. Cutter heads of one and one quarter inches in length having thirty-five or thirty-six notches along each edge have been made by this method and successfully operated.
  • the thickness of the guard member along the line opposite to the line defined by the ends of the cutter teeth is approximately .0055 of an inch.
  • the width of the notches is approximately .028 of an inch at the middle and the width of the notches is progressively reduced as the ends of the notches are approached.
  • the openingof the slots is approximately .004 of an inch wide.
  • the metal at ends 29, 29 of the guard member is thickter.
  • the movable cutter asbest shown in Figures 8, 9 and 10, comprises a series of sharply pointedv teeth It which are cut in the end face of the cut- These teeth are spaced a distance apart which is approximately equal to the distance between two of the notches H; of the guard member, and the length of the stroke of. the cutter is such that during theoperation of the device each of the points of the cutter teeth sweeps across two of the notches of the guard member.
  • Each of the rows of teeth of the cutter is adapted to be cut in a single operation by means of a multiple cutter of the type used in forming the notches of the guard member, which procedure greatly facilitates the production of the device.
  • the cutter is provided with cross-arms 34 by means of which it is guided in its movement in the guard member.
  • the individual teeth of the cutter are flat on top and their sides are slanted inwardly so as to define approximately a three-. sided pyramid having sharp edges 35, 35 and" meeting in a very fine cuttingp int 33. Due to the high speed at which the cutter is reciprocated, it is believed that substantially all of the cutting takes place at the points of the cutter teeth and as the hairs in the notches are not disturbed or contacted by anything prior to their meeting the cutter points, avery eflicient cutting action is effected.
  • each of the slots preferably is locatedat or adjacent to the edge of the g-uard member, and when the given number of the slots 'arranged'as described, the openings thereof overlap'eachother to an extent equal approximately to one-third the overall length of the guardmember so that a single up and down 'stroke of the'shaver in a straight line will serve to expose to the cutting edges of the device, substantially the entire area of the surface so travers'ed.
  • FIG 12 there is illustrated a form of cutter 90 which maybe used in connection with the cutter is provided with substantially the same number of teeth II as there are slots in the guard member. Very satisfactory results have been achieved by cutting the teethof the cutter so that the adiacent top edges of the teeth form an angle in a horizontal plane of approximately twelve degrees, as indicated at 02 in Figure 12.
  • the surfaces forming the cutting edges thereof may be ground and lapped without diificulty.
  • the shavers illustrated herein may be operated eifectively to cut the hair when translated across the skin at a much higher speed than has heretofore been considered feasible or proper for satisfactory results.
  • the double-headed cutter illustrated in Figure 1 is provided with four cutting edges which, if
  • the hair may be arranged to cut the hair at four different heights merely by varying of the width of the slots and the thickness of the guard bars along the line traversed by the points of the teeth of the cutters. It is preferred, however, to have both cutting edges at each side of the device adjusted for the same degree of cutting so that one head of the device cuts the hair closer to the skin than does the other. This arrangement is desirable because no two people have the same type of skin or hair, and where one cutting adjustment would be satisfactory for one person, the same might shave too closely to the skin for other people and by having a choice of two diiferent optionally usable cutter heads in a single device, it may be satisfactorily used by a much larger number of people.
  • the single-headed cutter shown in Figures 3 and 6 has two cutting edges which, if desired, may be arranged to cut the hair at different degrees of closeness to the skin, as previously suggested in connection with the shaving machine employing a double-headed cutter.
  • the bars of the guard member are extremely narrow and relatively thick at the point of admission of the hair so that there is little or no tendency on the part of the guard member for bending over the hairs or otherwise holding them away from the points of the cutter.
  • the thinnest portion of the guard bars is at the point of their greatest width so that ample strength is provided without, however, sacrificing close cutting qualities in the device.
  • the provision of a flat working surface at the underside of the cutter greatly facilitates the grinding and lapping operations performed in sharpening the edges at the underside of the guard bars defined by the notches or slots of the guard member.
  • Flanges or cross-arms such as 34 may be used with most of the cutters disclosed herein.. These elements serve to guide the cutter in its movement in the associated guard member and at the same time they define compartments below the cutting edges of the cutter for receiving the hairs which are sheared oil by the cutter.
  • the 7 litter receiving space thus provided may be readily cleaned without difiicult'y.
  • the outer edges or the cross-arms are relatively narrow in width so that they do not cause a great deal of friction at their line of contact with the guard member.
  • the narrow edge of the cross-arms has the added advantage in that there is little danger of hair and other material collecting between such edge and the guard member in quantities 'sufiicient to retard or stop the operation of the cutter.
  • This form of cutter is also effective in confining collected litter to certain localities and in keeping such litter away from certain of the operating parts of the shaver where it might cause damage.
  • the face-contacting or slotted portions of the various guard members may, for the. sake of convenience, be referred to as a shear plate.
  • a device of the type described comprising, a hollow outer guard member with transversely extending slots defining a plurality of closely spaced, widthwise extending cutter bars, a cutter member movably mounted inside said guard having transversely extending cutting elements contacting and cooperating with a portion only of each and every one of said cutter bars, portions of said cutter member adjacent to said cutting elements being spaced inwardly away from the inner surface of said guard member so as to define two longitudinally extending passageways, one at each side of the contacting portions of said cutter bars and said cutter elements, and means for translating said cutter member.
