Abstract: A band-type well obstructor for obstructing the well of the hub of a wheel rim, particularly for a pneumatic tire. The well obstructor has an inextensible band with integral circular protrustions mechanically extruded onto the band. The circular protrusions extend radially inwardly to abut against the base of the well to retain the band in position surrounding the well, and to resist crushing under the weight of the vehicle in the event of deflation of the tire. The well obstructor has a fastener assembly utilizing a screw with a groove adapted to receive a locking ring. The fastener assembly further has two transverse beams, one of which is adapted to fit over the end of the screw and abut against a locking washer placed between the transverse beam and the head of the screw. The locking ring is then snapped into place to hold this transverse beam in position. The second transverse beam is placed over the threaded end of the screw.

Abstract: A device for mounting and demounting a beaded pneumatic tire onto and off of a wheel which is particularly adapted for facilitating fitment of a well obstructor onto the well of the wheel. The device has a wheel support assembly which includes an upwardly extending spindle for supporting the wheel. The spindle has axially disposed internal female threads and has an exterior dimensioned so that the spindle can be freely inserted into the axial hole in the wheel. A removable bead pusher assembly is included which has a thrust collar, pusher arms, and a circumferential bead pusher ring connected to the ends of each of the pusher arms. A removable thrust assembly is provided which has a rotatable male threaded member which threadably mates into the female threads of the spindle and has a thrust face adapted to bear against the thrust collar.
