Abstract:
The invention provides a wheeled apparatus for transporting a brake assembly and/or a tire assembly from an aircraft. The apparatus contains a slideable hollow housing which can be adjusted in height by a jack associated with the apparatus. 
     A brake assembly can be placed within the housing for transportation or storage. On the bottom front of the housing is a stand for removing a tire assembly.

Description:
FIELD OF THE INVENTION 
     The invention relates to an apparatus for removing or replacing aircraft brake assembly and/or tire assembly. The apparatus is also used to store or ship the brakes or tires of aircraft. 
     BACKGROUND OF THE INVENTION 
     The tires and brakes of aircraft are constantly subjected to friction and stress which rapidly wear the brakes and tires. Because of safety regulations, the brakes and tires must be carefully examined and replaced when required in order to avoid any brake or tire-related accidents. 
     The brakes and tires of many commercial aircraft are huge and weigh heavily. These items generally require more than one person to remove and/or replace the tires or brakes. Generally, the items are handled manually and require a forklift or cart to transport the items after they are removed and sent to storage. In storage, the tires are stacked and the brakes must be carefully handled and stored to prevent scoring. After repair or inspection, the items need to be transported to be placed on the aircraft. Since the items are bulky and heavy, more than one person participates in the activity. The manual handling of the tires and brakes is time consuming and requires several maintenance personnel to act. 
     There is a need in the airline industry to provide a safer, easier and less costly method in man-hours to deal with the removal, replacement and/or storage of tires and brakes. 
     SUMMARY OF THE INVENTION 
     There is provided an apparatus for assisting in the removal and/or replacement of brakes and/or tires of an aircraft. Accordingly, there is provided a cart having a frame comprising a pair of spaced apart vertical tube members joined at the bottom by a rear horizontal bar having a wheel attached at each end of the horizontal bars extending at a back end perpendicularly from each end of the bottom bar. The horizontal bars are joined at a front end by a front tube member. The front tube member has a vertical bar at each end and is parallel to the back bar. A housing for the brake assembly is placed on the frame for housing the brake assembly. Support means is provided for supporting a brake assembly placed into the housing and means on the bottom front end of said apparatus for supporting a tire assembly outside of the housing. Preferably, the brake assembly is mounted into a separate container which is placed in the housing. 
     Advantageously, there is provided a means for adjusting the height of said housing to permit proper alignment of said tire assembly or brake assembly so as to remove it and slide it into position in the housing. 
     It is a general object of the invention to provide an apparatus to assist in the removal and/or replacement of an aircraft brake assembly or tire assembly. 
     It is another object of the invention to provide a means for transporting and storing an aircraft brake assembly. 
     It is yet another object of the invention to provide an apparatus which can assist in removal and storage of an aircraft brake assembly using only one person. 
     It is yet another object of the invention to provide a much safer way of removing the brake assembly and tire assembly without injury to personnel. 
    
    
     These and other objects will be better understood from the drawings and from the description of the preferred embodiments.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     As shown in FIG. 1, the apparatus  10  of the invention comprises a frame  11  on which a housing  12  is slideably and removably mounted. The frame  11  has a pair of wheels  13  at least mounted at the rear of the frame so as to maneuver the apparatus  10 . The housing  12  has a cavity  14  into which there can be placed a brake assembly  15  from an aircraft. Preferably, the brake assembly  15  is mounted within an optional container  16  to prevent any damage to the brake assembly  15  while handling. A cover  17  having a support  18  covers the housing  12  when the brake assembly  15  is being transported or housed. A lock nut  19  is used to lock the cover  17  in place when it is placed on the housing  12  with the support  18  extending through an opening  15   a  of the brake assembly to a rear opening in the housing  12  (not shown). 
     At the bottom of the housing  12  is a pair of arms  20  which can be extended out through the front of the housing  12  so as to be used to remove a tire assembly. 
     FIG. 2 illustrates a further embodiment of the invention. In FIG. 2, an apparatus  22  comprises a frame  23  that is formed by vertical tubes  24   a ,  24   b ,  24   c , and  24   d . The vertical tubes  24   a ,  24   b ,  24   c , and  24   d  are connected at the bottom of three sides with tubes  24   a ,  24   b ,  24   c  and at the front with a bar  26  which together with tube  25   b  holds a jack  26  for raising and lowering the housing. At the ends of tube  25   b  is a pair of wheels  28   a ,  28   b . Optionally, there may be front wheels  29  at the bottom of tubes  24   a ,  24   b  for use with heavy loads. 
     The housing  27  has channels  30  so as to be slideable along the vertical tubes  24   a ,  24   b ,  24   c , and  24   d . A jack  26  moves the housing  27  up and down so as to position the housing  27  to receive a brake assembly. The jack  26  can be either mechanical or pneumatic. 
     The frame has a handle member  33  which is associated with the rear vertical tubes  24   c ,  24   d  for maneuvering the apparatus  22 . An optional container is used to house a brake assembly before it is placed within the housing  27 . The rear of the housing.  27  can have on its interior a support member  34  which passes through an opening in a brake assembly to support and stabilize it within the housing  27 . 
     On the rear of the housing  27  there is provided a stand member  35  upon which the apparatus will rest while in storage. These raised portions are separated so as to be accessible to a forklift for storage. 
     As shown in FIG. 3, a fire stand for transporting tires can be placed at the bottom of the apparatus. A pair of arms  20  are located in the bottom of the housing which can be swiveled out of the housing and dropped and locked into a slot  2   a . The apparatus can be used to remove and transport tires alone or with a brake assembly housed within the housing. 
     The housing can be about 16 to 18 inches in depth and should contain an opening so as to house the container for the brake assembly which is generally 22″×22″×13″ and can contain most brake drums. The radius of a brake assembly is normally about 8½ inches and contains an opening through which a support in the housing or on the cover can pass. 
     Preferably, the housing and the insert container comprise a heavy duty plastic such as polycarbonate, nylon or the like. 
     In operation, an empty housing is slid onto the frame. A brake assembly is removed from an aircraft and placed on a support within the housing. A cover is placed on the housing and the housing is wheeled to storage. The housing is placed on the outside stand members on its rear and the frame removed from the channels in the housing. The housing can thereafter be fork lifted into position for storage. 
     Alternatively, when the cover contains the brake assembly support, the brake assembly is placed onto the cover. The housing is placed over the brake assembly by itself or in a protective container and the support is locked on the back of the housing. The housing can thereafter be lifted and wheeled to storage. 
     Although the, invention has been described with preferred embodiments, it is understood that variations and modifications may be employed without departing from the concept of the invention as defined in the claims.
