     BACKGROUND OF THE INVENTION 
     The present invention relates, generally, to the field of hairbrushes, and specifically toward a hairbrush having elongated handles that can be used in different ways. Hairbrushes are extremely conventional for use in grooming hair as well in styling the hair. Typically, a hairbrush is constructed of a handle and a brush head having bristles thereon of varying thicknesses and stiffness for use with a variety of hair types to achieve various styles. 
     U.S. Pat. No. 1,951,023 discloses a brush including a handle having a mass of sponge rubber secured thereto. The handle is disclosed to be collapsible and is composed of two or more telescoping members one of which is embedded within the mass of the sponge rubber with an inner member being slideable into and out of an embedded member to form other convenient extending handles. 
     U.S. Pat. No. 2,641,012 illustrates a brush that has telescoping handle parts that form extendable sections of a hairbrush One part of the handle section has a larger diameter while other sections are progressively smaller whereby the various sections can telescope within each other to form a longer or shorter handle. 
     U.S. Pat. No. 3,690,331 discloses a combined brush and comb including a body having tufts on an exterior surface of the body and a comb that may be adjusted for various angles with respect to the body of the brush and included are retractable handles. In one embodiment the handles are extendible from either end of the brush body to facilitate its use by either a right-handed or a left-handed person. 
     BRIEF DESCRIPTION OF THE INVENTION 
     The inventive concept of the instant invention hereby disclosed is a specific hairbrush that includes a handle upon which a grooming roller can be moved from one end of the handle to the other depending on the needs of the beautician due to styling requirements or mere left- or right-handedness. The concept also allows for the grooming roller to be moved from end to the other, or removed altogether, during styling in order to provide a space for another hairbrush having a different circumferential size or different brushing elements as long as the inner diameter remains the same so as to conform to the outer diameter of the handle.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIGS. 1A-1D  illustrate a first embodiment that discloses a hair brush having hair brush head  1  with bristles  2  thereon. The hair brush head  1  consists of two halves  1   a ,  1   b  that form an internal chamber that can snugly house an elongated slideable handle  9  that can move the brush head  1  from one end of the handle  9  to the other and can be locked thereat. The two halves of the brush  1  have contained therein in a groove  4  at either end a flexible ring  3 . The flexible ring  3  has push buttons  5  which, when the two halves  1   a ,  1   b  are assembled, fit in a hole  7  formed by the two halves  1   a ,  1   b . The flexible ring  3  further has two inwardly directed arrest buttons  6 . The operation of this embodiment is such that if the brush head  1  is located on one end of the handle and locked into place by the arrest buttons  6  after having penetrated into the openings  8  in the handle, the operator merely has to push the two push buttons  5  inwardly thereby flexing the ring  3 , which will then release the two arrest buttons  6  from the holes or opening  8  in the handle  9 , and the brush head  1  can be moved to the other end of the handle  9 . When the pressure on the push buttons  5  is released, the two arrest buttons on the other end of the brush head  1  will settle back again into the holes  8  on the handle  9  and the brush head  1  will be relocated to the other end of the handle. 
       FIGS. 2A and 2B  show a second embodiment of how a brush head  1  can be locked in place at either end of a handle  20 . In this embodiment there are shown two end push buttons  21   a  and  21   b  at either end of the handle  20 . Each one of the push buttons  21   a ,  21   b  is connected to activating rods  21 ,  22 . Each inner end of the activating rods  21  and  22  are now connected to a rotating lever  23 , which can rotate around a pin  23   a  in the inner confines of the handle  20 . The outer ends of the rotating lever  23  keep balls  25 ,  26  at an opening in the hair brush head  1  in an arrested position. The rotating lever  23  is kept in this position and in contact with the balls  25 ,  26  by a coil spring  24 . When it is desired to move the brush head  1  from one end of the handle  20  to the other, it is merely up to the operator to push one of the end push buttons  21   a ,  21   b  inwardly, thereby activating the respective rod  21 ,  22  causes the rotating lever  23  to rotate to some extent and, whereby, the pressure on the balls  25 ,  26  will be released and the brush head  1  can be moved. Upon release of the pressure from either push button  21   a ,  21   b , the balls  25 ,  26  will again lock into an opening at the end of the brush head  1  and lock the same into place because of the resetting of the lever  23 . 
       FIGS. 3-3D  illustrate a similar embodiment as was explained with regard to  FIGS. 2A-2B . At either end of the hollow handle halves  2   a  and  2   b  there are again two push buttons  36 ,  37  which again, like in  FIG. 2 , each operate on an activating rod  34 ,  35 . The ends of each of the activating rods  34 ,  35  are connected to a rotating disc which has dimples at its outer periphery to accept two arresting balls  31 ,  32 . In an activated position the two balls will enter two openings at the ends of the brush head  1  to lock it in place. Again, as explained in  FIG. 2 , there is a coil spring (not shown) that keeps the disc in an activated position and thereby the balls  31 ,  32  in a locked position. Upon pushing either one of the push buttons  36 ,  37 , the respective activating rod  34 ,  35  will rotate the disc  30  and take the balls  31 ,  32  out of engagement with one of the holes  33 , (seen in  FIG. 3D , at the end of the brush head  1 ) and the brush head  1  can now be moved to the other end of the handle  20 . 
       FIG. 4  illustrates still another embodiment of how a brush head  1  can be moved to the other end of the handle  20 . At both ends of the handle  20  there are two respective push buttons  40 ,  41 . Each one of the push buttons  40 ,  41  is connected to a respective sliding sleeve  42 ,  43 . Each of the sliding sleeves  42 ,  43  have a sleeve-like end at their inner ends. In the middle of the interior of the hollow handle there is located a flexible activating element  45  that has camming surfaces  44 ,  46  at its outer ends. The camming surfaces  44 ,  46  can be overridden or overlapped by each of the sleeve-like inner ends of the sliding sleeves  42 ,  43 . A centering spring  51  is located inside the flexible activating element  45  and also extends to the insides of each of the sliding sleeves  42 ,  43 . The flexible activating element  45  has two outwardly extending protrusions  47 ,  48  which normally are engaged with arresting holes  49 ,  50  at each of the ends of the brush head  1 . When it is desired to move the brush head  1  from one end of the elongated handle  20  to the other end, the operator can push either push button  40  or  41  whereby either sliding sleeve  42 ,  43  with its sleeve-like inner end will ride over either the camming surfaces  44 ,  46  of the flexible activating element  45  to thereby distort the flexible activating element  45  and take the protrusions  47 ,  48  out of engagement with the arresting holes  49 ,  50  at either end of the brush head  1  and release the same to be moved to the other end of the handle  20 . 
     The rollers can also contain a head-conducting material, such as copper, to allow the rollers on the brush to act like hot rollers when used with a heat source, such as a blow dryer.
