Abstract: A portable bead breaking apparatus useful for breaking the bead of an ATV-type, low-pressure, balloon tire away from a safety rim upon which the tire is mounted. The apparatus applies carefully directed downward and inward pressure at opposing sides of the tire bead. By applying pressure in this manner against the bead, the bead is broken without injury to the tire and the tire may then be removed from the rim. The apparatus is portable and collapsible into a convenient storage pouch so that an ATV operator may readily carry the device with him or herself when operating the vehicle in regions remote from a tire service facility. Using the apparatus, an operator may readily remove a tire and repair damage thereto. The tire may then be remounted and reinflated.

Abstract: A pusher mechanism for attachment to the carriage, saw guard, or other appropriate point of a rotary-blade stone slab saw. Using either signals from a controller of a modern slab saw or self-generated sensor information, the pusher is actuated at a precise time in the cutting process and applied an outward pressure on the severed slab to ensure that the slab is directed away from the saw blade. While a pneumatic cylinder is typically used, either hydraulic, electro-mechanical, or mechanical mechanisms may also be used to accomplish the push-away function.
