     DETAILED DESCRIPTION OF THE INVENTION 
     Referring now specifically to the drawings, an improved compressed air device is illustrated in  FIG. 1  and is shown generally at reference numeral  10 . The device  10  includes a base  12 , a motor  14 , and at least one compressor  16 , as shown in  FIGS. 1-6 . Preferably, the device  10  will include two compressors  16  that are mounted to the base  12 . The base  12  may have a plurality of sides. As illustrated in  FIG. 1 , the base has a first side  18 , a second side  20 , and a third side  22 . Each side ( 18 ,  20 , and  22 ) has a top portion and a bottom portion. The top portion of the sides ( 18 ,  20 , and  22 ) is the exposed portion or the portion that is more easily accessible to a user when the device  10  is in the upright position. By way of example, the motor  14  is positioned on the top portion of the first side  18 , as illustrated in  FIG. 1  and the compressors  16  are positioned on the top portion of the second side  20  and third side  22 . The bottom portion of the sides ( 18 ,  20 , and  22 ) is the portion opposite the top portion. 
     The base  12  may have any form, but as illustrated in  FIG. 1 , the base has a substantially triangular form. The term substantially triangular form means that the base includes three primary sides that may be adjacent to one another. In other words, the sides may intersect. The term substantially triangular form may also mean that the three primary sides do not intersect, but the planes of the sides intersect at a point or are an asymptote. 
     The sides ( 18 ,  20 , and  22 ) of the base  12  are in a spaced apart relationship forming a void  24  within. As illustrated in  FIG. 1 , the motor  14  is positioned within the void  24  and is engaged to the top portion of the first side  18 . The motor is fastened to the top portion of the first side by a bolt, screw, weld, or the like. 
     The second side  20  of the base  12  includes at least one pair of slots  26 . The third side  22  of the base  12  includes at least one pair of slots  26 . Preferably and as illustrated in  FIG. 8 , the second side  20  and third side  22  of the base  12  includes two pairs of slots  26  disposed on each side ( 20 ,  22 ). Each compressor  16  preferably contains a fastener that extends from the bottom of the compressor  16 . The fastener may be a belt, screw, threaded extension or the like. In the examples, a threaded extension is utilized as a fastener and extends from the compressor  16  and is inserted into the slots  26 . By way of example only and as shown in the figures, the compressor  16  includes four (4) threaded extensions or bolts that extend downward and are inserted into the slots  26 . Each bolt contains a threaded end for receiving a correspondingly threaded nut. The threaded extension also receives a correspondingly threaded nut. 
     The compressors  16  are slidingly engaged to the top portion of the second side  20  and the top portion of the third side  22  of the base  12  with the use of an adjusting plate  28 . As illustrated in  FIGS. 8 and 10 , the adjusting plate  28  comprises a face  30 , a lip  32 , and a rib  34 . The face  30  of the adjusting plate  28  contains at least a pair of bores  36  for receiving the fastener that extends from the bottom of the compressor  16 . Preferably, the face  30  of the adjusting plate  28  contains two pairs of bores  36  for receiving the fastener that extends from the bottom of the compressor  16 . The lip  32  is positioned about 90° with respect to the face  30 . The lip  32  contains at least one threaded bore  38 . Preferably, the lip  32  contains two threaded bores  38 . The rib  34  of the adjusting plate  28  is optional, but can be added to provide strength and stability to the adjusting plate  28 . 
     During use, an adjusting plate  28  is positioned on the bottom side of the second side  20  of the base  12 , and an adjusting plate  28  is positioned on the bottom of the third side  22  of the base  12 , as shown in  FIG. 8 . The bores  36  of the adjusting plate  28  are aligned with the slots  26  of the second side  20  and third side  22  of the base  12 . The fastener disposed on the bottom of the compressor  16  is received within the slot  26  of the sides ( 20 ,  22 ) and the bore  36  of the adjusting plate  28 . As set forth above and by way of example only, the fastener is a threaded fastener engaged to the bottom side of the compressor  16  and when the threaded fastener is inserted through the slot  26  and bore  36 ; a nut may be selectively secured to the threaded fastener, thus allowing the compressor  16  to be selectively secured or engaged to the adjusting plate  28 . 
     The second side  20  and third side  22  of the base  12  contain a hole  40  positioned in close proximity to the area where the second side  20  and third side  22  are engaged, as shown in  FIG. 7 . A threaded fastener  42  is received within the hole  40 . The threaded fastener may be a bolt, screw, or the like. As illustrated in  FIGS. 3-8 , the threaded fastener  42  is designed to be inserted into the threaded bore  38  positioned on the lip  32  of the adjusting plate  28 . The threaded fastener  42  received within the hole  40  positioned on the second side  20  is received within the threaded bore  38  of an adjusting plate  28  positioned beneath the bottom side of the third side  22 . Likewise, the threaded fastener  42  received within the hole  40  positioned on the third side  22  is received within the threaded bore  38  of an adjusting plate  28  positioned beneath the bottom side of the second side  20 . 
     During use, the threaded fastener  42  is rotated, causing the adjusting plate  28  to translate or adjust along the side ( 20 ,  22 ) of the base  12 . Preferably, the device  10  will include a pair of threaded fasteners  42  that are received within a pair of threaded bores  38  disposed on the lip  32  of the adjusting plate  28 . Therefore, when both of the threaded fasteners  42  are rotated, the adjusting plate  28  translates or adjusts along the side ( 20 ,  22 ) of the base  12 , as illustrated in  FIGS. 4 and 5 . It should be noted that the term translates or adjust means that the adjusting plate  28  moves relative to the side ( 20 ,  22 ). By way of example only, as shown in  FIG. 5 , the adjusting plate  28  moves a distance “d”, causing the center point of the compressor to move a distance “x” from the motor  14 . The side ( 20 ,  22 ) is stationary and the adjusting plate  28  moves relative to the side ( 20 ,  22 ). In one embodiment, as the threaded fasteners  42  are rotated in the clockwise position, the adjusting plate  28  moves upwards or towards the juncture where the second side  20  and third side  22  are engaged. As the threaded fasteners  42  are rotated counterclockwise, the adjusting plate  28  moves downward or toward the first side  18 . Since the compressors  16  are engaged to the adjusting plates  28 , the position of the compressors  16  are adjusted by the movement of the adjusting plate  28 . 
     As illustrated in  FIG. 6 , the motor  14  includes a drive wheel  44  and each compressor  16  includes a slave wheel  46 . A belt  48 , as shown in  FIGS. 2 and 3 , is positioned on the drive wheel  44  and the slave wheel  46 , allowing the motor  14  to supply rotational energy to the compressor  16  for operating the compressor  16 . For the device  10  to run efficiently, economically, and smoothly, the belts  48  must contain the optimum amount of tension. During the rotation of the threaded fasteners  42 , the compressors  16  are adjusted for providing the optimum amount of tension in the belts  48 , as illustrated in  FIGS. 4 and 5 . Additionally, a protection shield may be positioned over the drive wheel  44 , slave wheel  46 , and the belts  48  to protect the safety of user of the device from getting limbs, hair, or clothing tangled with the gears ( 44 ,  46 ) and belts  48 . The protection shield also reduces the amount of dirt or debris that enters the wheel ( 44 ,  46 ) and belts  48 . 
     As illustrated in  FIG. 1 , a mounting foot  52  may be engaged to the device  10  for selectively securing the device  10  to a structure. The mounting foot  52  may be selectively secured to the device  10  by fasteners, such as a bolt, and the mounting foot  52  may be selectively secured to the structure by a fastener, such as a bolt. As illustrated, the mounting foot  52  may be selectively secured to the first side  18 , second side  20 , or third side  22  of the base  12 . 
     In another alternative embodiment of the present invention as shown in  FIG. 10 , the base  112  may have a generally trapezoidal shape. In other words, the base  112  may have four sides. The only difference between this embodiment and the embodiment described above is the fourth side  154 . The motor may be positioned on the fourth side  154  or within the cavity. 
     Although the present invention has been illustrated and described herein with reference to preferred embodiments and specific examples thereof, it will be readily apparent to those of ordinary skill in the art that other embodiments and examples may perform similar functions and/or achieve like results. All such equivalent embodiments and examples are within the spirit and scope of the present invention and are intended to be covered by the following claims.
