Definitions

  • the hair cutting device as disclosed in my aforementioned US. Pat. No. 2,731,717 has aligned projecting tines which, while protecting the skin from cutting, provide a means to expose cutting edges to the hair and simultaneously to avoid the collection of cut hair within the device.
  • a double-edged blade is supported and is adjustable between two sets of tines and can be transversely adjusted to various cutting positions within each of the tine areas.
  • the blade is held in parallel relation to, and bisects, the bights of the aligned tines when in cutting position and is conveniently adjusted by means of a rack and pinion controllable by a knob placed along the handle for the convenience of the operator.
  • a hair cutting device of somewhat greater size than the earlier models as disclosed in the aforementioned Spanel patents.
  • the cage made up of tines, is wider.
  • improved adjusting means by which the blade can readily be adjusted to the various cutting positions.
  • the devices are designed so that the blade and rack length are approximately one-half of the total distance from the extremities or bights of one set of tines to the other set.
  • the throw of the rack by the adjusting knob permits the blade to be adjusted within the two sets of tines to the extreme outward position in each set without the rack protruding from the housing adjacent the cutting regions since such protrusions would in part defeat the purposes of the enclosing cage. It has been discovered that increasing the width of each set of tines approximately one-fourth inch provides better cutting configurations particularly when used on long hair but in adding this additional length, it becomes impossible to use the mechanism of the old device without the rack protruding from the housing if a blade of approximately the same size is used.
  • a scotch yoke type of lever means is used whereby adjusting the knob which is centrally located at the handle of the device will cause a crank arm to engage a lever which in turn is attached to the blade table or carrier. As the knob is turned, the crank will cause the lever to swing about an are which is translated into rectilinear motion since the blade table engages a straight track, thus allowing the adjustment of the blade from one extreme side or set of tines to the other side of the device or second set of tines.
  • a second embodiment discloses the use of a threegear arrangement to accomplish the objectives as described with respect to the scotch yoke embodiment.
  • the knob is connected to a driving gear which in turn meshes with two driven gears on either side of the drive gear both of which in turn mesh with the rack which is connected to the blade table.
  • the blade table may be adjusted from its one extreme position to the second extreme position with one of the driven gears meshing with the rack at all times.
  • a curvilinear pivotal interior rack is used which meshes with a centrally located pinion gear to provide an extended range of motion to the blade carriage while the mechanism itself is compact and designed to be fitted within appropriate contours of the cutter device.
  • tine width is a means of improving the performance of the cutter but also additional improvement is achieved when the tines are formed into various shapes as illustrated in the drawings whereby the hair may be more effectively cammed to produce not only better cutting ability but also what approximates a tapered look in avoidance of a chop type of hair cut whereby unsightly ridges are present.
  • the tines may be slanted at an angle to better cam the hair or they may be constructed in such a manner that approximately one-eighth inch of the extreme tine portion is perpendicular to the longitudinal axis of the device, while the remainder of each tine is slanted to promote hair camming.
  • the 4; inch perpendicular extremity provides for better control of the device particularly in regions of the hair where a hair part is formed.
  • Serpentine shaped tines may also be used effectively to cam the hair and may be used totally for each tine or in part with a portion remaining perpendicular to the device as described in the previous embodiments. Camming action may also be increased by twisting small nubs or dull barbs into portions of the tines.
  • both the front and opposite back sides of the cutter may be effectively used. This is a result of adding bends near the tine extremities so that the tines extend inwardly generally toward each other to provide clearance paths for hair being stroked and cut regardless of the side of the frame facing the scalp.

  • FIG. 17 is an enlarged partial plan view in which serpentine tines are substituted for the tines of the earlier figures;
  • FIG. 18 is a side elevational view of FIG. 17;
  • FIG. 19 shows variations of serpentine tines

  • FIG. 22 shows variations of the twisted barb tines
  • FIG. 23 shows variations of graduated serpentine tines as differentiated from the serpentine tines in FIG. 17.
  • FIGS. 1-16 illustrate a variety of alternative means for advancing the blade and blade carriage to cutting positions first with respect to the first set of tines and then with respect to the second set of tines.
  • the width of the tines and the distance of the span between the bights of the two sets of tines has been increased without increasing the blade width thus necessitating improved mechanical arrangements for advancing the blade so that it may extend to the outermost cutting positions without the rack protruding from the housing adjacent the cutting regions.
  • a lever-crank arm mechanism whereby a control knob 34 is turned to rotate a crank arm 38 which, in turn, is engageable with a pivoted lever 42 anchored at one end to an extension of the blade carriage which is slidable from tine extremity to the other tine extremity.
  • the hair cutter 10 of FIG. 1 comprises a handle 12 and a cage portion 14.
  • a blade carriage 16 Within the cage portion, a blade carriage 16 is positioned with its end extremities extending into carriage guide ways 18 and 20.
  • a double-edged type blade 22 is mounted upon the blade carriage 16 by means of a spring clamping plate 24 which engages slotted mounting posts 26 by means of key slots 28 of the clamping plate.
  • the blade 22 is enclosed within the cage 14 by means of hair dividing elements or tines 30.
  • the blade adjusting mechanism is located in the enlarged portion 32 of handle 12. Extending above the handle enlarged portion 32 is a thumb-wheel or control knob 34 which may easily be operated by the thumb.
  • the knob 34 is rigidly secured by means of a stud 36 (see FIGS. 2 and 4) to a crank arm 38. At its extremity the crank arm 38 has a rigidly attached stud pin 40 which engages lever arm 42 within slot 44.
  • the lever arm 42 is pivotally mounted on a stud pin 46 and secured to the neck portion of handle 12.
  • the opposite end of the lever arm 42 engages the carriage slide 48 which is part of the blade carriage structure 16, by means of a carriage pin 50 centrally and rigidly mounted on the carriage slide 48.
  • the lever arm 42 has a carriage slot 52 which engages the carriage pin 50 and is of sufficient length to permit the lever arm 42 to swing an arc around pivot point 46 thus permitting the carriage slide to be adjusted along the range of positions between the limiting positions respectively shown in FIG. 4 and FIG. 5.
  • the driving arrangement just described makes possible the use of a carriage slide 48 which in the region of the connecting pin 50 need only be of size to support that pin. It is shown of width which in its limiting position will not project beyond the apexes or bights of the tines 30.
  • the driving connection of pin 50 moves from one side of the longitudinal axis of symmetry, across that axis to a position on the other side of that axis.
  • the carriage slide 48 which is slidable across the width of the hair cutter has down-turned end or lip 54 which is slidable in a transverse recess 56 of the enlarged handle portion 32.
  • control knob 34 has indexing teeth 60 between which extends the V- shaped end of a spring member 58 which is itself secured to the handle portion 32.
  • the spring 58 extends into the handle enlarged portion 32 through a slit 6] and has a locking arm 62 secured to the inner surface of handle portion 32.
  • the remainder of each of the tines is slanted and is designated by 65.
  • the slanted tine portions 65 give very definite advantages in camming each subdivided portion of the hair in such a manner as to prevent a chop or ridged type of hair cut which will result unless the hair is moved sideways to produce a tapered cut as opposed to being cut with the individual hairs lying side by side in a normal combed position.
  • the straight portion 64 of the tines provides for better control in regions of the hair where a hair part is formed and assists in stroking the subdivided hair.
  • the hair cutter bottom handle portion formed by the base plate 66 extends to the farthest cage extremity and is there formed into a carriage guideway 18.
  • the respective sets of tines are mounted to a cage base plate 66 on their one side and as shown in FIG. 3, a single piece of wire may be used for each complete tine, half being used for the angulated tine of the one set and half being used for the angulated tine of the other set.
  • each free end-portion may be inwardly bent as at 70 to extend a substantial distance toward the plane in which the cutting blade is moved in selection of the desired cutting position.
  • the tines can be made longer than illustrated thus to position the clamping element 72 even farther away from the bend 70.
  • the position of the clamping element 72 provides for clearance for movement thereby of the blade clamping posts 26 when the blade is to be positioned near a selected row of apexes of the tines. The distance between the clamping elements 72 provides adequate room to remove and insert replacement plates though this distance may be shortened.
  • the termination points generally illustrated in FIG. 3 are such that blade relacement is facilitated with minimum handling thereof. This is a desirable safety feature.
  • the hair cutter as illustrated in FIG. 3 and other embodiments later to be described can be used with either angulated side facing the scalp materially to increase the utility of the device as a whole.
  • the user has the advantage of knowing that when the cutting edge is disposed near the bend 70, reproducible cutting actions will be achieved and thus serves as a good reference point for the trimming of hair as best serves the objectives of the user.
  • the blade clamping plate 24 has an upturned end 74 to allow the clamp to be slid to disengage the slots from the slotted posts 26 to allow the easy removal of the clamping plate and then the blade. Also, it will be noted that the plates 72 are located inwardly of bends 70 so as to not interfere with the combing action of the tines. In fact the combing action is facilitated. Thus, either side of the cage 14 may face the scalp for right or left hand gripping of handle 12, a marked improvement.
  • the tines 76 which are closest to carriage guideway 18 and the tines 68 which are closest to carriage guideway 20 are slightly shorter than the remaining tines. These shorter end-tines act as a stopping means or blade-stop to prevent the blade from striking any of the other tines as it is advanced to its furthermost cutting positions, thus serving to prevent nicking and dulling of most of the blade edge which would occur should the blade edge strike against the other tines. It is emphasized that all the bights may be aligned and the nicking of an edge of the blade 22 prevented by the side of the link or lever 42 engaging the inclined wall (serving as a stop) of the enlarged portion 32 of the handle 12.
  • FIGS. 6-11 an alternate embodiment of the hair cutter of FIG. l is shown.
  • like reference characters will in general be used to identify like parts.
  • the primary differences in this embodiment from that of FIG. 1 are that a different type of blade adjusting mechanism is used and slanted tines 114 that are totally slanted are employed.
  • the mechanism broadly comprises a three-gear arrangement, two of the gears being driven by the third with the two gears being engageable at spaced positions with a rack gear 108 which is part of the carriage 110.
  • the driving gear is 100 and is engageable with the driven gears 102 and 104. It will be noted from FIG. 7 that the driving gear 100 is turned directly by means of knob or thumb-wheel 34.
  • the driven gears 102 and 104 engage a rack 108 which is a part of the carriage 110.
  • driving gear 100 also rotates counterclockwise causing driven gears 102 and 104 to be driven in a clockwise direction which shifts the carriage, blade and rack gear to the position shown in FIG. 9 where the blade 22 abuts tines 112 which are shortened as are the end tines of FIG. 1.
  • the rack 108 is approximately the width of the blade carriage and when the blade is less than one-half of the distance from tine extremity to tine extremity it is necessary that the driven gears 102 and 104 be positioned so that the rack is always engaged by one of the gears.
  • gear 102 when the rack is in the position shown, it is still in engagement with gear 102.
  • the driving gear 100 when the knob 34 is turned clockwise, the driving gear 100 also turns in a clockwise direction causing engaging driven gears 102 and 104 to turn in a counterclockwise position thus causing the rack 108 to move toward the limiting position shown in FIG. 10.
  • the total movement of that rack exceeds twice the distance from the longitudinal axis of symmetry to the aligned bights. This is achieved with a rack of less length than one-half of its travel by using driving means operable in positions above and below the axis of symmetry.
  • the upper pinion gear 102 and the lower pinion gear 104 meet these requirements, the joint operation by them being shown in FIG. 6 and the transfer of the driving connection first to one and then the other being shown in FIGS. 9 and 10. It will be noted that the travel distance of the rack 108 may be increased by amounts proportional to the separation distance between said driven gears.
  • the hair engaging portions of the tines 114 are slanted, i.e., lie in inclined planes.
  • the slanted tines enable the hair to be cammed slightly in the direction of the tine slant so that as the hair has a sidewise movement as it engages the blade, the hair also engages the cutting edge at an angle to provide more of a tapered look. This minimizes cutting the hair in a chopper manner, i.e., a straight across type of cut.
  • a link or lever 148 is at one end pivoted by pin 46 secured to the handle portion and at its opposite end has a slot 52 into which extends pin 50 secured to an end portion of the carriage 48.
  • the lever 148 Intermediate the ends of the lever 148 is an arcuate rack 149 with associated driving pinion 150.
  • the pinion 150 is secured to the stub shaft of thumbwheel or knob 34 journaled in the housing forming an enlarged portion of the handle.
  • the cutting edge of blade 22 is in close proximity to the bights of tines 30. That edge is close enough for shaving but does not become nicked or dull along the working edge of the blade by engaging the tines, for the upward movement as viewed in FIG. 15, is limited by the lever 148 engaging the housing as at 153 serving as a stop. Also, the pinion 150 engages the lower end of the curved slotted portion of lever 148. Stopping means of this kind avoids the use of shortened end tines to arrest movement of the carriage 48. As shown in FIG. 16, like arrangements limit the movement of carriage 48 in the downward direction, as viewed in that figure.
  • open corners 32a and 32b of the enlarged handle-housing portion 32 provide for slightly increased arcuate movement of rack 149 without actual protrusion from the outer boundary of the housing portion 32.
  • the configuration of FIGS. 17 and 18 may be preferred.
  • the tines 116 have straight portions 116a extending in direction normal to the longitudinal axis of the carriage 48. They then have zig-zag or serpentine shapes 1 16b substantially until the region of their securement to the frame or base plate 66. As the hair traverses the zig-zag paths, the camming action takes place for substantially all positions of the cutting edges of the blade 22.
  • FIGS. 17 and 18 Variations of the serpentine arrangement of FIGS. 17 and 18 are shown in the single tine illustrations of FIG. 19.
  • the number of angle-bends in the tine 138 may be less than for the tine 140.
  • Either of these shapes may also be inclined as illustrated by tines 142 and 144.
  • the tines have lateral projections 120a extending outwardly therefrom. They are formed by sharp bends in the wire forming the tine. They serve to narrow a portion of the path between adjacent tines through which the hair must pass. With the edge of the blade adjacent this narrowed region, efficiency of cutting will be increased. Because the hair is cammed slightly and comes from spaced portions of the scalp, the dreaded chopped-look is avoided and the desired professional appearance is produced. As best shown in FIG. 20, the hair guiding protruberances 120a may be near the bights of the tines.
  • they may be located nearer the base plate 66 to delineate cutting regions farther from the scalp and from the bights of the tines. See tines 145, 146 and 147 of FIG. 22 for variations in formed protuberances.
  • the tines of each side of the cage may be of zigzag configuration as shown in FIG. 23, characterized by increasing angularity from one bend to the other beginning with the bight portion and extending along the lengths of each tine.
  • the angularity between the bends can also decrease from the bight ends along the lengths of the tines, thus providing adjustability as to the camming action for different positions of the cutting blade relative to the angled portions.
  • the blade adjusting mechanism need not be restricted to the crank and arm, the three-gear-rack or the curvilinear rack embodiments for the purposes of this invention to be carried out.
  • the criteria of the subject invention is met. With this design, it is possible to use a blade whose width is less than half the distance from the extremities of one set of tines to the other set.
  • Variations may also be made in the angles of the tines with the important consideration being that the various shapes as disclosed herein cause a camming action of the hair to produce a more tapered cut than has heretofore been possible with the earlier cutter models.
  • a hair cutter comprising:
  • a protective cage supported by and extending outwardly from the frame, said cage comprising a plurality of elements forming oppositely disposed rows of bights respectively spaced outwardly from said frame, the distance between said rows of bights being greater than twice the Width of said doubleedged blade,
  • a range-of-motion-enhancing means disposed intermediate of said driving element and said carriage to assist in driving said carriage toward and away from said oppositely disposed rows of bights to enable positioning of the cutting edges of said blade at selected positions between each of said oppositely disposed rows of bights
  • said range-ofmotion-enhancing means comprising a motion imparting member pivotable about a point on said supporting frame to provide a range of motion capability to drive said blade carriage from one to the other of said oppositely disposed rows of bights in which said double-edged blade is in juxtaposition to first one and then the other of said oppositely disposed rows of bights.
  • said range-ofmotion-enhancing means comprises a pivotally mounted lever which when driven by said driving element, increases the throw of said blade carriage.
  • said driving element comprises a driving gear
  • said intermediate rangeof-motion-enhancing means comprises two driven gears spaced one from the other and engageable with said driving gear
  • said carriage includes a rack gear engageable by said driven gears to increase the travel distance of said rack by amounts proportional to the separation distance between said driven gears.

  • the hair cutter of claim 1 in which the plurality of elements includes projecting portions which substantially cam a users hair.
  • a hair cutter comprising:
  • said cage comprising a plurality of tines to form hair receiving spaces throughout their respective lengths but for parts of which are substantially bent upon themselves to form projections which intercede within the hair receiving spaces to deflect portions of hair as said hair cutter is stroked through the hair.
  • a hair cutter comprising:
  • a protective cage supported by and extending outwardly from the frame, said cage comprising a plurality of tines forming oppositely disposed rows of bights respectively spaced outwardly from said frame, the distance between said rows of bights being greater than twice the width of said doubleedged blade, the end portions of said tines of each of said rows in regions remote from said bights extending inwardly toward said frame to provide clearance paths for hair being stroked and cut regardless of the side of the frame facing the scalp,
