BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to quilting racks. More specifically, the invention is a tabletop quilting rack for use with a sewing machine. The quilting rack has a laser pointer guide, rollers to hold the raw material and the assembled quilt, a carriage, and an aluminum track on which the carriage rides. 
     2. Description of the Related Art 
     The related art of interest describes various quilting racks, but none discloses the present invention. There is a need for a quilting rack which is secured adjacent to a sewing machine which rides on a carriage of the rack. A laser pointer guides the tracing of a pattern on the quilt. The related art of interest will be discussed in the order of their perceived relevance to the present invention. 
     U.S. Pat. No. 4,192,241 issued on Mar. 11, 1980, to Donald K. Reed et al. describes an apparatus for quilting layered fabrics comprising a quilting frame including a sewing machine on a movable carriage. The sewing machine has an extensible sewing head for free-hand quilting. The apparatus has a large rectangular frame with six telescopic legs with three legs on each side. The sewing machine carriage is mounted by linear anti-friction bearings on parallel rails extending from side to side on the frame. Other parallel rails and anti-linear friction bearings extend transversely of the pattern and mount the linear bearings and carriage for movement longitudinally of the quilting fabric. A follower depends from the sewing machine carriage to engage and follow the pattern and controls movement of the carriage to conform to the pattern selected for quilting. The fabric and linear shafts may be adjusted and rotated to maintain the required tension on the material being quilted, and to assure a completed quilt free from wrinkles. The apparatus is distinguishable for requiring a sewing machine with a telescopic head and a large support for manufacturing purposes. 
     U.S. Pat. No. 5,913,275 issued on Jun. 22, 1999, to John F. Flynn describes a multiple use quilting frame comprising a quilting frame for hand quilting or machine sewing quilting. The frame has three parallel spaced rods individually rotated and locked in a rotated position by engaging splines on the ends of the rods and on the frame ends by the use of a screw threaded knob-type wing nut. The top and bottom layers of the quilt are attached to certain rods and batting inserted from a fourth rod. The three quilt layers are attached to and wound on a third rod, and manipulated for either hand stitching or machine sewing with the rods maintaining the quilt in a taut condition. The device is distinguishable for requiring the addition of batting from a roll between the two rolls of the quilt layers.

     None of the above inventions and patents, taken either singularly or in combination, is seen to describe the instant invention as claimed. Thus, a quilting rack for sewing machines solving the aforementioned problems is desired. 
     SUMMARY OF THE INVENTION 
     The present invention is directed to an efficient and reliable quilting rack device integrated with a domestic sewing machine to enable the accurate free-motion machine quilting of one or two layers of fabric material including optional batting between the two fabric layers. One can stitch in any direction, and feel artistically free to make free-hand and stippling designs. Since, the sewing machine moves on its movable rack, there is less stress using this device than pulling the material through a stationary sewing machine. A laser light pointer element in front of the sewing machine on the top plate is provided for tracing patterns from a template placed on the right of the sewing machine. The quilting rack device has a horizontal rectangular aluminum frame with a lower carriage on four wheels travelling from one end to the other. A second carriage on four wheels translates forward and backward while carrying the sewing machine as a rider, and are not clamped to a table. A pair of upright aluminum side angle pieces on each side of the base forward of the sewing machine support plastic racks which hold three metal tubes. The front tube No.  1  rolls clockwise to roll up the unrolling fabric sheets fed from the middle roller No.  2  (top sheet) rotating clockwise and the rear roller No.  3  (bottom sheet) rotating counter-clockwise. There are stops on the lower carriage to prevent the sewing machine from rolling off. The domestic sewing machine can be a pattern programming machine, but the invention prefers manual patterning. Two metal tubes or rollers are arranged to enable the material to roll over with improved support and minimum sag. Hitch pin clips are utilized to hold the metal tubes in place. Slots are formed in the tube supports for an elastic band to slide through to hold the quilt snug from side to side. The elastic band has a snap fastener on one end for fastening to the tube support slot. The quilting rack device can be attached to a wall by brackets and used without a sewing machine and its carriages to free-hand stitch the quilt design. 
     Accordingly, it is a principal object of the invention to provide a quilting rack device which is combined with a domestic sewing machine on its own movable track to sew free-hand a quilting pattern on a quilt precursor fabric sheet. 
     It is another object of the invention to provide a quilting rack device having a laser light pointer for tracing patterns from a template. 
     It is a further object of the invention to provide a quilting rack device having a second carriage translating the sewing machine forward and backward. 
     Still another object of the invention is to provide a quilting rack device which can be mounted on a wall without using a sewing machine and the carriages by free-hand stitching the quilt design. 
     It is an object of the invention to provide improved elements and arrangements thereof for the purposes described which is inexpensive, dependable and fully effective in accomplishing its intended purposes. 
    
    
     These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The present invention is directed to a quilting rack  10  illustrated in FIG. 1 for sewing machines  12  preferably, but can be used without the sewing machine by positioning the rack  10  on a shelf (not shown). The rack  10  has a U-shaped metal frame  14  having a pair of extending side rails  16  supporting a front rail  18  and a rear rail  20  to form a rectangular metal frame  22 . The side rails  16  are actually a queen base extension rail  17  combined with a king base extension rail  19  (hidden inside) adjusted by a knobbed screw  21  to accommodate different lengths of exposed combined fabric sheet material to be stitched together. A first rectangular wheeled carriage or queen carriage  24  translatable from side to side from the extending side rails  16  on the rectangular metal frame  22 . A second rectangular wheeled carriage or king carriage  26  translatable forward and backward on the first wheeled carriage  24  supports the sewing machine  12 . Each of the pair of extending side rails  16  supports an upright roller support element  28  which has a roller support arm  30  horizontally arranged perpendicularly to each upright roller support element  28 . A set of three rollers, i.e.,  32  (rear),  34  (middle) and  36  (front), extend between the roller support arms  30  to supply, tension and load, respectively, to a quiltable fabric sheet material  38  comprising two fabric sheets with or without an intermediate batting layer to be quilted. The rollers are formed from rubber or flexible plastic tubes on aluminum tubes. Each of the rollers are rotatable only in one direction. A laser pointer device  40  located on the right side of the second wheeled carriage (king)  26  and positioned by a laser pointer mounting element  42  (FIGS. 19A-19C) to incline slightly toward the sewing needle  43  by an inclined throughbore  44 . A hand-made or commercially available pattern stencil (not shown) is used to mark a pattern on the quiltable fabric sheets  38 , whereby the quiltable fabric sheet material  38  can be patterned by the sewing machine  12  following the illuminated stencilled pattern on the movable quiltable fabric sheet material  38 . 
     Each horizontal roller support arm  30  is adjustable in height on each upright roller support element  28 , and has a pair of straps  46  for tensioning the quiltable fabric sheet material  38  from side to side with pins  48  as seen in FIG.  1 . It should be noted that the pins  48  are used only temporarily to hold the sheet material  38  taut until the stitching is completed for that segment of the fabric sheet material  38 . 
     The first rectangular wheeled queen carriage  24  has four grooved wheels  50  with two wheels on each side traversing on top of the parallel front rail  18  and the rear rail  20  attached to the front portion of the pair of extending side rails  16 . The second rectangular wheeled king carriage  26  has four grooved wheels or sheaves  50  with two wheels on each side traversing on top of the parallel side rails  52  of the first rectangular wheeled queen carriage  24 . 
     The unidirectional rotations of the three rollers will be described now with reference to FIG. 1 from the front of the apparatus. The rear supply roller  32  rotates only in a counter-clockwise direction as depicted by a directional arrow, where as the loading roller  36  and the tension or intermediate roller  34  rotate only in a clockwise direction. The unidirectional rotation of the three rollers are controlled by a set  54  of a pawl and a gear wheel (serrated in a direction to hold the pawl) on one end of each roller. The two sheet materials  38  from the clockwise rotating roller  32  and the counter-clockwise rotating roller  34  come together with an optional batting layer (not shown) already installed on one or both of the unrolling sheets, and are rolled up counter-clockwise on the loading roller  36 . 
     In FIGS. 1 and 2, the rectangular metal frame  22  has a welded mid-brace  56  and a diagonal brace  58  formed of unflanged metal strips for reinforcing the frame  22 . The pair of right-angled extending side rails  16  are secured to the narrow ends of metal frame  22  by knobbed set screws  21  through apertures  64 . The side rails  16  in turn support the upright roller support element  28  which is actually a composite of two flanged rails  66  providing a space for a pair of wing nuts  68  to hold the horizontal roller support arm  30  between the flanges at a predetermined adjustable height. 
     Returning to a more complete description of the upright roller support element  28  depicted in FIGS. 2 and 6, and the is horizontal roller support arm  30  illustrated in FIGS. 2,  3 ,  6 , and  18 , the horizontal roller support arm  30  has a straight upper surface  70  and enlarged rear head portion  72  for supporting the three rollers  32 ,  34  and  36  in fixed straight horizontal position with wire clips  74  outside the roller support arm  30  in apertures  64  of the roller ends and bushings  76  inside the enlarged apertures  78  of the support arm  30 . 
     The advantage of adjusting the level of each horizontal roller support arm  30  without twisting on each upright support element  28  with the two in-line wing nuts  68  enables the sewer to position any sewing machine  12  to the enabling position for proper stitching of the fabric sheet material  38 . 
     The wooden or metal rod  80  at the front edge of the second rectangular wheeled carriage or king carriage  26  and extending past its sides enables control of the second carriage forward and rearward. 
     FIGS. 4 and 5 depict an exploded view of the smaller top king carriage  26  and the lower queen carriage  24 , respectively. The heavy duty white polyethylene rectangular king plate  82  in FIG. 4 has a parallel pair of bottom aluminum angle rails  84  shown also in FIGS. 14A (side view) and  14 B (top view) with apertures  64  for bolting to the corners of the king plate  82  with bolts  60  and nuts  62 , and the wood or metal control rod  80  in front. The four grooved wheels or sheaves  50  are attached to the angle rails  84  by similar nuts and bolts into apertures  64 . In FIG. 4, the laser pointer device  40  is mounted in the inclined throughbore  44  of the laser mounting element  42  as discussed earlier in FIGS. 19A and 19B. The mounting element  42  has a notch  86  at the end opposite the laser mounting throughbore  44  in its upper surface to fit against the side and bottom of the king plate  82  and held there by the doubly apertured rectangular plate  88  of FIG. 19C on top of the edge of king plate  82  by a wing nut  68  and a bolt  60  in the proximate aperture for easier loosening for movement of the mounting element  42  to another position. The distal fastener is a bolt  60  and nut  62 . 
     The queen plate  90  in FIG. 5 is made of similar material and is a larger rectangular plate than the king plate  82  (see FIGS. 17A and 17B) with its pair of parallel bottom side rails  92  attached by bolts  60  and nuts  62  which also fasten the upper pair of parallel side rails  94  which are perpendicular to the bottom side rails  92 . The upper rails  94  have a welded stop plate  96  to prevent the rear wheels or sheaves  50  of the king plate  82  with the sewing machine  12  from moving further back off the upper rails  94 . The lower rails  92  support the queen plate  90  on four wheels  50  on bolts  60  with nuts  62 . 
     Turning to FIGS. 7A-C, one of the pair of longer main track frame sides  18  and  20  approximately 66 inches in length is depicted in FIG. 7A with flanges  98  on the bottom and outside apertures  64  for joining with the pair of flanged end pieces  100  with one end piece illustrated in a side view in FIG.  7 B and in a top view in FIG.  7 C. The large apertures  102  in FIG. 7B are for the knobbed adjusting screws  21  to extend the side rails  16  of the frame  14 . The smaller apertures  64  proximate the ends of flanged end pieces  100  and the main frame sides  18  are for joining the main track frame sides  18  to the end pieces  100  to form the rectangular metal frame  22  for the carriages  24  and  26 . 
     FIGS. 8A-C are representative of the king extension pair of bottom angle rails  84  in FIG.  4  and the shorter upper queen extension pair of the upper angle rails  94  and the shorter pair of equal sized bottom rails  92  with larger apertures  78  in FIG.  5 . 
     FIG. 9 depicts cross braces  104  of different lengths for the rectangular frame  22  (FIG. 1) with apertures  64 , for the queen carriage  24  (hidden under the plate), and for the king carriage  26  (hidden under the plate) which are fastened to the flanges of the aforementioned angle elements. 
     FIG. 10A illustrates the main spacer or mid-brace element  56  for the metal frame  22 . FIG. 10B shows the stop plate  96  on the queen carriage  24  in FIG.  1 . FIG. 11 depicts the left side support or the extending side rail  16  of the base frame  14  shown in FIG.  1 . FIGS. 12A and 12B show, respectively, a side view and a top view of the top left rail  94  with an aperture  64  on the left for the stop plate  96  of FIG.  5 . FIGS. 13A and 13B show, respectively, top and side views of one of the pair of bottom rails  92  supporting the queen plate  90  of FIG.  5 . FIGS. 14A and 14B illustrate a side view and a top view, respectively, of one of a pair of bottom rails for the king plate  82  which are shorter in length than the bottom rails  92  of the queen plate  90 . In FIG. 15, one pair of the upright roller support element  28  is shown with the flanges  66  separated for inclusion of the In FIGS. 16A,  16 B and  16 C, a system of increasing the lengths of the rubber or plastic rollers on metal tubes  106  to accommodate the quilting of blankets for a regular size bed, a queen size bed or a king size is illustrated. The larger queen size bed blanket is accommodated by inserting the queen extension roller  108  (FIG. 16B) and its exposed insert portion  106  into one end of the main regular size bed roller  110  (FIG.  16 A). If a king size bed blanket is to be stitched, the king extension roller  112  is added to the queen extension roller  108  via its insert portion  106 . The apertures  64  provide securement of each roller segment by pins (not shown here). The metal frame must be enlarged to accommodate the increased roller lengths. 
     FIGS. 17A and 17B, respectively, show the relative sizes of the queen plate  90 , e.g., 20 in. by 8 in., and the king plate  82 , e.g., 18 in. by 8 in. with appropriate apertures  64 . The sizes of the plate rails would have commensurate sizes. 
     FIG. 18 is the horizontally arranged roller support arm  30  for positioning on each upright roller support element  28  (FIG.  1 ). Arm  30  is preferably made of white plastic or Teflon (TM) in the shape shown with a straight upper edge  70 , an enlarged head  72  for supporting the rear supply roller  32  (not shown) and the tension roller  34  (not shown) in the apertures. The two smaller apertures  64  are for fastening to the upright roller support element  28 .
