       [0033]    The same reference numerals refer to the same parts throughout the various Figures. 
       DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0034]    With reference now to the drawings, and in particular to  FIG. 1  thereof, the preferred embodiment of the new and improved adjustable cosmetic brush system embodying the principles and concepts of the present invention and generally designated by the reference numeral  10  will be described. 
         [0035]    The present invention, the adjustable cosmetic brush system  10  is comprised of a plurality of components. Such components in their broadest context include a chambered brush handle, an adjustable ferrule and an elongated tuft of bristles. Such components are individually configured and correlated with respect to each other so as to attain the desired objective. 
         [0036]    From a specific standpoint, in the preferred embodiment of the invention, first provided is a cosmetic brush handle. A cosmetic brush handle has an outer cylindrical shaft varying in diameter and length made of hard material that is formed with an interior chamber area. The cosmetic brush handle also has an upper collar with opposing vertical channels and an upper perpendicular cavity approximately one quarter to one half inch in depth recessed into the top of the cylindrical collar which is approximately one and one half inches in length and varies in diameter with respect to the predetermined shaft length and diameter. 
         [0037]    Next is a cosmetic brush ferrule assembly. The cylindrical ferrule assembly is formed by outer and inner ferrule couplers each having upper and lower openings. The outer coupler rotates laterally around the inner coupler and both have correlating channels to guide lateral movements. The outer coupler has an upper oval shaped opening opposite of the inner couplers upper oval shaped opening. Rotating the ferrule outer section clockwise and counterclockwise around the inner coupler increases or decreases the combined ferrule assembly uppermost opening surface area or diameter clutching the tuft of bristle fibers. The ferrule inner section has curved inside walls with small aligning tabs protruding towards the center of the ferrule assembly for telescoping along the vertical handle collar channels. When the ferrule assembly outer and inner coupler upper oval shaped openings are aligned the inner coupler can be telescoped vertically along the brush handle collar channels. 
         [0038]    Lastly provided is a plurality of bristle fibers made of various materials, lengths, thicknesses and rigidness. Extended lengths of bristle fibers are selected to form upper, lower and middle sections when bundled into various diameter tufts for a range of cosmetic application purposes which correspond with the brush handle specifications. The tufts are aligned by the lower section ends and secured with a bonding adhesive and a round clasp. The lower section secured end is then fixed into the brush handle collar top recessed opening. The bristles opposing upper section loose end is fed through the ferrule assembly lower then upper opening to extend outward to form the cosmetic application brush head. The middle section formed by the elongated bristles remains enclosed within the ferrule assembly while fully extended for application practices. Only when the ferrule is retracted to the lowest cleaning position is the middle section extended from the ferrule system opening to access constricted brush heal areas in the upper section. 
         [0039]      FIGS. 1-9  illustrate the preferred embodiment of the adjustable cosmetic brush system, designated by reference numeral  10 . The adjustable cosmetic brush system  10  is for adjusting the ferrule assembly tension clutching the elongated plurality of bristles protruding outward from the dual coupler ferrule upper oval shaped openings while vertically telescoping positions along the chambered handle collar to increase effectiveness of the system to allow cleaning constricted bristles in brush heal areas and modifying the application contour shape of the grouping of bristles in the extended vertical application position. 
         [0040]    The front region of the brush assembly has a configured handle with a lowermost handle base  12  and a vertical shaft  14  which has a tapered thickness and varies in total length and diameter. The upper handle shaft section has a cylindrical collar  16  that has a diameter slightly less than the handle shaft. Approximately one fifth up the length of the handle shaft  14  is a collar base  18  with a small radius ledge that transitions the handle shaft and collar sections. The handle collar has opposing vertical channels  20  that extend upwards from the collar base  18 . 
         [0041]    Mounted to the handle collar assembly is an adjustable ferrule assembly  22 . The ferrule assembly has a lower section  24  and an upper section  26 . The ferrule assembly lower section  24  has a thicker diameter ferrule adjustment  28  molded into the ferrule assembly outer casing. The adjustment has recessed notches  30  encompassing the diameter for gripping purposes. The ferrule assembly upper section  26  has an uppermost opening  32  for which a plurality of bristle fibers  34  extend outward from the opening. The upper section of the tuft or plurality of bristle fiber tips are arranged in predetermined lengths aligned at the opposing lower section ends connected by the tuft middle section to form the application brush head  36 . The purpose of the upper, middle and lower tuft sections is further explained in  FIG. 7  and  FIG. 8 .  FIG. 1A  shows an exploded view of the ferrule assembly upper section  26  and uppermost opening  32  identified by letter A. The area bristles exit a brush nearest the ferrule is commonly referred to as the brush heal  38 . Bristles in this region closest to the ferrule assembly are held tightly by clutch tension  40  from fastening the tuft of bristles lower section within the ferrule. Cosmetic brushes are routinely cleaned to remove cosmetic material, dirt, oil and other contaminants that accumulate in this constrained area  42  which is difficult to access while cleaning due to the tightly held bristle formation required shape the brush head for cosmetic application purposes. 
         [0042]      FIG. 2  shows a front view of the adjustable cosmetic brush system ferrule assembly in the fully extended application position designated as V 1 . The ferrule assembly  22  can be rotated laterally approximately one quarter the brush collar diameter in a clockwise direction (Curved Arrow  44 ). Referencing  FIG. 3 ,  FIG. 4  and  FIG. 6 , when the two ferrule assembly oval shaped openings are aligned parallel to one another (designated as L 2  in  FIG. 6 ) the ferrule assembly  22  can be retracted vertically to the lowest cleaning position (Arrow  46 ) along the collar channels  20 . 
         [0043]    Next,  FIG. 3  illustrates an upper cross sectional view of the adjustable cosmetic brush system ferrule assembly internal components taken along line  3 - 3  of  FIG. 2 . The ferrule assembly  22  encompasses an outer coupler  48  that is affixed to the inner coupler  50 . The outer coupler  48  has an interior curved wall  52  that has a rotation guide tab  54 . The outer coupler also has a lateral rotation guide channel  56  which has a clockwise stop  58  and a counterclockwise stop  60 . The inner coupler has an outer curved wall  62  with a comparable rotation guide tab  64  that travels back and forth within the outer coupler channel  56 . The inner couplers outer curved wall  62  also has a comparable lateral rotation guide channel  66  with a counter clockwise stop  68  and a clockwise stop  70  for which the outer coupler rotating guiding tab  54  travels back and forth within the inner coupler guide channel  66 . Between the outer coupler and inner coupler is a small clearance gap  72  that allows the outer coupler to rotate laterally by twisting the ferrule adjustment  28  in a clockwise motion (Curved Arrow  44 ) and counter clockwise motion (Curved Arrow  74 ). The inner coupler  50  has an interior curved wall  76  which has opposing vertical guide tabs  78  that travel vertically within the handle collar channels  20 . The outer coupler has an uppermost oval shaped opening  80  and the inner coupler has a comparable oval shaped opening  82 . The oval shaped openings alignment to one another increases or decreases the ferrule assembly uppermost opening diameter  84  which alters clutch tension  40  applied to the plurality of bristles fibers  34 . 
         [0044]    Referencing  FIG. 4 , the inner coupler vertical guide tabs  78  are fastened to the handle collar vertical channels  20  that precludes inner coupler lateral rotation. In  FIG. 3  the outer coupler  48  is shown in the furthest counter clockwise position within the ferrule assembly lateral rotation guide channels designated as L 1 . The outer coupler opening  80  is positioned approximately 90 degrees from parallel alignment with the inner coupler opening  82  in this designated L 1  position. Now referencing  FIG. 2  and  FIG. 6 , the outer coupler  48  can be rotated laterally in a clockwise direction (Curved Arrow  44 ) around the fastened inner coupler  50 . The furthest clockwise travel rotation allowed within the coupler channels is when the inner and outer coupler vertical guide tabs reach the inner and outer coupler channel stops. In this position designated as L 2  the outer coupler opening  80  is aligned parallel to the inner coupler opening  82 . The purpose of the L 1  and the L 2  ferrule assembly lateral positions is further explained in  FIG. 5  and  FIG. 6 . 
         [0045]    Next,  FIG. 4  illustrates an upper cross sectional view of the adjustable cosmetic brush system ferrule assembly internal components taken along line  4 - 4  of  FIG. 2 . First shown is the lower ferrule adjustment  28  and adjustment notches  30  have a perpendicular upper ledge  86  that encompasses the outer coupler  48  external curved wall  88 . Next referencing handle collar  16  which has an exterior cylindrical wall  90  and opposing vertical channels  20  intended to guide the inner couplers opposing vertical guide tabs  80  while vertically telescoping the ferrule assembly  22 . There is a small gap  92  between the handle collar exterior wall  90  and inner couplers interior wall  76  to allow clearance for the ferrule assembly to telescope vertically along the handle collar  16 . The collar  16  also has an interior cylindrical wall  94  which the area between the collar interior walls  96  is where the lower section secured end of the bristle tuft is fastened to the brush handle (further shown in  FIG. 8  and  FIG. 9 ). 
         [0046]    Now referencing  FIG. 5 , the perspective illustration shows the adjustable cosmetic brush system ferrule assembly  22  telescoped and retracted to the lowest cleaning position designated as V 2  which exposes the lengthened bristles within the tuft middle section  98 . While the ferrule assembly was in extended application use position V 1  the brush heal  38  was located at reference point  100 . Telescoping the ferrule assembly to the lowest cleaning position V 2  releases the clutch tension  40  from bristles in the constricted area  42  creating a non-application brush head  102  preventing the plurality of bristles  34  from functioning as intended to apply cosmetic products which allows effectively cleaning and removing unwanted debris and contaminants that accumulate in the constrained areas of the brush heal  38  shown in  FIG. 1A . Once cleaning practices are completed, the ferrule assembly  22  can be extended upward (Arrow  146 ) back to the fully extended application position V 1  which returns the needed clutch tension  40  to the tuft middle section  98  to once again form the application brush head  36  and repositions the ferrule assembly  22  for alignment to rotate counter clockwise back to position L 1  to adjust the desired application brush head contour for intended and effective cosmetic application purposes. 
         [0047]    Next,  FIG. 6  illustrates an upper cross sectional view of the adjustable cosmetic brush system internal ferrule assembly components taken along line  6 - 6  of  FIG. 5 . The ferrule assembly is positioned in the clockwise position designated as L 2  with the outer coupler opening  80  aligned parallel with the inner coupler opening  82  allows the ferrule assembly to vertically telescope between designated position V 1  and position V 2 . Also referencing  FIG. 3  with the ferrule assembly in the extended application position V 1  and rotated to lateral position L 1 . First laterally rotating the ferrule assembly between position L 2  and position L 1  increases or decreases the uppermost opening diameter  84 . From lateral position L 2  the ferrule assembly  22  can be rotated counter clockwise (Curved Arrow  74 ) from designated position L 2  to designated position L 1 . The surface area or uppermost opening diameter  84  is gradually reduced as the ferrule assembly  22  gets closer to designated position L 1  therefore increasing the ferrule assembly clutch tension  40  applied to the plurality of bristles  34  which adjust the formed brush head contour for improving cosmetic application purposes (further shown in  FIG. 8 ). 
         [0048]    Next  FIG. 7  is a front cross sectional assembled view of the present invention taken along lines  7 - 7  of  FIG. 5 . To explain how the adjustable cosmetic brush system internal apparatuses achieves the designated L 2  and V 2  positions. First the outer coupler  48  rotation guide tab  54  travels clockwise within the inner coupler  50  rotation guide channel  66  as the ferrule assembly  22  is rotated to designated position L 2  which aligns the outer coupler oval opening  80  and inner coupler oval opening  82  so the ferrule assembly  22  can now move along the tuft middle section  98 . Next the inner coupler  50  vertical guide tabs  78  travel within the collar channels  20  as the ferrule assembly  22  telescopes and descends vertically to the lowest cleaning position designated as V 2  where the ferrule adjustment  28  stops at the collar base  18 . In this cleaning position the uppermost opening  32  holding the plurality of bristles is moved to the tuft lower section  104  creating the non-application brush head  102  from exposing the increased length of bristles in the tuft middle section  98  however this position allows effectively cleaning contaminants from the tuft upper section  106  and buildup area  42  where the ferrule assembly application position began identified by number  100 . Next the ends of the tuft lower section  104  are secured by adhesive and a clasp  108  and then affixed to the perpendicular collar floor  110  within the collar interior walls  96  approximately one half inch in depth from the top of the collar. 
         [0049]    Next,  FIG. 7  shows and explains additional internal components of the present invention. The handle shaft  14  has front and rear exterior walls that form a lower interior chamber  210  and a middle interior chamber  212  separated by a lower interior wall  214  and an upper chamber  216  is formed within the collar  16  that is separated from the middle interior chamber  212  by an upper interior wall  218 . Secured inside the middle chamber  212  is a rechargeable battery  220  connected to electrical wiring  222  that supply power to a small motor  224  that has a shaft  226  affixed with a counterbalance weight  228 . Operating the motor  224  cause vibrations to be sent through the handle shaft  14  and through the collar floor  110  and through the plurality of bristles  34  to the brush head  36  to vibrate the bristle fibers which increases the brush systems efficiencies during cosmetic product application. The motor  224  is turned on and off by a sensor  230  that is mounted to the interior chamber wall  232  that can be activated with pressure placed to the outside of the interior chamber wall  234 . Secured inside the lower interior chamber  210  is an inductive coupling receiver  236  for wireless battery charging when coupled to a compatible charging device. 
         [0050]    Next,  FIG. 8  is a front cross sectional assembled view of the present invention taken along lines  5 - 5  of  FIG. 2 . When the ferrule assembly is in designated position V 1  the brush system can be operated for cosmetic application while in position L 1  or L 2  depending on the individuals preference. The ability to adjust the uppermost opening diameter  84  and the clutch tension  40  allows changes to the brush head contour shape  310 . During cosmetic application practices the individual can select between wider or a narrower application brush head  36  by changing between designated positions L 1  and L 2 . The ferrule assembly  22  shown in  FIG. 8  is in designated position L 2  which forms a wider brush head contour designated as W 1 . The ferrule assembly  22  can be adjusted to designated position L 1  which decreases uppermost opening  84  will cause a narrower brush head contour to form designated as W 2 . Either lateral ferrule assembly position allows cosmetic application practices to be performed effectively. 
         [0051]    Lastly,  FIG. 9  is an exploded perspective view of the adjustable cosmetic application brush system. The application brush head  36  is formed by a plurality of bristles  34  bundled into an elongated tuft having an upper section  106  a lower section  104  and a middle section  98  which are secured at the lower section ends by adhesive and a clasp  108  that is then passed through the upper oval shaped opening  80  of the outer coupler  48  and then passed through the upper oval shaped opening  82  of the inner coupler  50  and then the bundle is affixed between the collar interior walls  96  and the ferrule assembly is attached to the handle collar  16  and collar channels  20 . 
         [0052]    As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
         [0000]    With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
         [0053]    Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
