Abstract: A two-part axially separable chuck for pneumatic tires characterized by a valve system and lock which prevents separation of its parts while a mounted tire thereon is inflated under air pressure. A normally closed safety valve is disposed downstream from a main air supply and exhaust valve which cannot be opened until after the parts are manually lacked against separation. After being locked against separation, the parts cannot be manually unlocked until after the tire is deflated by opening the exhaust valve. The main valve system may be in the form of a conventional two position supply and exhaust valve with a single actuator or both the supply and exhaust valves may be operated by separate valve actuators. The safety valve is spring loaded to closed position and is manually moved to open position shortly after locking of the parts occurs. A single operating lever controls movement of the lock and opening of the safety valve. Resilient adapter rings are also employed to accommodate tires of various bead diameters and an adjustment is provided for tires of various widths between the beads.

Abstract: Apparatus for breaking the beads of tires mounted on heavy vehicles such as earth movers and including a generally U-shaped frame for straddling the tire and positioning one of a pair of bead breaking fingers on each of the opposite sides of the tire adjacent the wheel rim flange. Each bead breaking finger is carried on the inner end of a member slidably mounted on one of the frame arms for movement generally parallel to the wheel axis and adapted to be engaged by a fluid operated ram. Upon the application of force, one of the finger support members is forced inwardly to move the tire bead away from the bead seat. The incident angle of the bead breaking fingers may be adjusted to correspond to different wheel sizes.

Abstract: Portable tire bead breaking tool characterized by a body member having a pair of fixed spaced wedges and a movable pusher foot of like shape disposed therebetween; a pivoted lever for initially forcing the fixed wedges radially inward between a tire bead and a wheel rim flange; and a second pivoted lever for thence moving the pusher foot laterally relative to the fixed wedges for further forcing the bead away from the flange to a released position. A releasable device locks the second lever to the body member during the initial wedging action and, when unlocked, permits the second lever to translate the pusher foot through connecting linkage.
