       DETAILED DESCRIPTION OF THE INVENTION 
       [0017]    Electrical machines such as, for example, motors and generators often include poles that include metal plates that are wound with wire. The rewinding procedure for a pole includes removing the pole from the electrical machine, and removing the wire from the pole. The metallic plate of the pole includes mounting holes that are often threaded and are operative to mount the pole to the electrical machine. Often a mounting plate is fabricated with holes that match the size and location of the mounting holes in the pole. The pole is attached to the mounting plate, and the mounting plate and pole are secured to a rotating apparatus such as a lathe machine. The rotating apparatus includes a shaft and a fixture or chuck attached to the shaft that is operative to secure objects, such as the mounting plate, to the rotating shaft. A portion of a wire is attached to the metal plate of the pole and the pole is rotated by the rotating apparatus. The wire is wound about the metal plate as the plate rotates forming the rewound pole. 
         [0018]    In a workshop environment, a variety of different types of poles may be rewound. The different types of poles may include metallic plates with mounting holes having a variety of mount hole locations, diameters, and thread pitches. To mount different types of poles on a rotating apparatus, a mounting plate is fabricated with holes that match the mount holes of each type of pole. Thus, for each pole having different mount hole dimensions, a unique mounting plate is fabricated. The illustrated embodiments described below include a mounting apparatus that allows poles having a variety of different mount hole locations, sizes, and thread pitches to be attached to the mounting apparatus that is secured to the rotating apparatus without fabricating a unique mounting plate. 
         [0019]      FIG. 1  illustrates a perspective view of an example of a pole  100 . The pole  100  includes a plate portion  102  and mount holes  104 . The mount holes  104  have a diameter (d) and may include a threaded interior surface. 
         [0020]      FIG. 2  illustrates a perspective view of an exemplary embodiment of a mount block member (mount block)  202  and a spacer member (spacer)  204 . The mount block  202  may be formed from, for example, a metallic material such as steel or another metallic material. The mount block  202  includes a body portion  201  and extension portions  203  that extend from opposing sides of the body portion  201 . The extension portions  203  may include holes  205  that pass through the extension portions  203 . The body portion  201  defines an orifice  207  having a diameter (d′). In the illustrated embodiment, the orifice  207  has a threaded inner surface  209 . The spacer  204  includes a threaded outer surface  211  having an approximate diameter d′ and a smooth inner surface  213  having an approximate inner diameter d, that corresponds to the diameter d of the mount holes  104  of the pole  100  (of  FIG. 1 ). The orifice  207  is operative to engage and retain the spacer  204 . 
         [0021]      FIG. 3  illustrates an exemplary embodiment of mount blocks  202  and spacers  204  attached to the pole  100  with fasteners  302 . In this regard, the spacer  204  is inserted into the orifice  207  of the mount block  202 . The inner diameter of the spacer  204  is aligned with the mount hole  104  (of  FIG. 1 ) and the assembly is secured with the fastener  302  that is threaded into the mount hole  104 . The use of the spacer  204  allows the mount block  202  to be used with poles  100  having different sized mount holes  104 . For example, if a similar pole having a different arrangement of mount holes  104  is used, a spacer  204  having an inner diameter corresponding to the inner diameter of the particular mount hole  104 , and a corresponding fastener  302  may be used to secure the mount block  202  to the pole  100 . Though the illustrated embodiments include a mount block  202  and spacer  204  arrangement that allows the mount block  202  to be used with a variety of different sized mount holes  104  (by using an appropriately sized spacer  204 ), alternate embodiments may include a mount block  202  having a smooth bore orifice  207  sized to correspond to the diameter of a particular mount hole  104  without the use of the spacer  204 . The center of mass of the illustrated embodiment is illustrated by the point  301 . 
         [0022]      FIG. 4  illustrates a perspective view of a rotating apparatus  400  and a portion of a mount assembly  404 . In the illustrated embodiment, the rotating apparatus  400  includes a stationary portion  401  and a rotating portion  402 . The rotating portion includes mounting plates  403  that are attached with an arrangement of fasteners. Though the illustrated embodiment includes two mounting plates  403 , alternate embodiments may include a single mounting plate  403 . The mount assembly  404  includes a channel assembly  406  that is attached to the mounting plate  403  with an arrangement of brackets  408  and fasteners (not shown). The channel assembly  406  includes opposing side members  405  that define opposing channels  407 . The channels  407  are sized and shaped to engage the extension portions  203  of the mount blocks  202  (of  FIG. 2 ). The channel assembly  406  includes a base plate portion  409 . The base plate portion  409  and side members  405  of the illustrated embodiment are formed from a single, continuous blank material. However, an alternate exemplary embodiment may include a base plate portion  409  that is attached to distal ends of the side members  405  with fasteners (not shown). 
         [0023]      FIG. 5  illustrates a perspective, partially transparent view of the mount assembly  404  with the pole  100  mounted to the mount assembly  404 . In this regard, the extension portions  203  of the mount blocks  202  slidably engage the channels  407  of the channel assembly  406 . The axis of rotation of the rotating apparatus  400  is indicated by the line  501 . 
         [0024]      FIG. 6  illustrates a perspective, partially transparent view of the mount assembly  404 . The illustrated embodiment includes a cap plate portion  602  that is secured to the channel assembly  406  with fasteners following the mounting of the pole  100  to the mount assembly  404 . The cap plate portion  602  includes a threaded orifice that engages an alignment member  604 . In the illustrated embodiment, the alignment member  604  includes a threaded bolt or stud that engages the cap plate portion  602 . The alignment member  604  extends through the cap plate portion  602  and contacts the mount block  202 . The alignment member  604  is adjustable and is operative to exert a force on the mount block  202  along the longitudinal axis of the mount assembly  404 . 
         [0025]      FIG. 7  illustrates a perspective, partially transparent view of the mount assembly  404 . The illustrated embodiment includes an alignment member  604  similar to the alignment member  604  described above that engages the base plate portion  409  and contacts the mount block  202 . The alignment members  604  exert opposing forces on the mount blocks  202  that retain the position of the mount blocks  202  (and attached pole  100 ). Since the alignment members  604  are adjustable, they may be adjusted to secure and align the pole  100  with the rotational axis of the rotating apparatus  400  (of  FIG. 4 ). 
         [0026]    The mount assembly  404  described above allows poles  100  having a variety of mounting hole arrangements to be mounted to the rotating apparatus  400  with the mount assembly  404  without fabricating a mounting plate for each type of pole  100 .
