Abstract: A bumper holder for securely supporting an automobile bumper includes a movable carriage and an adjustable cradle that has indexable arms with slidable brackets attached thereto. The adjustable cradle is configurable into a collapsed storage position and an expanded holding position adaptable to receive various sizes and configurations of automobile bumpers. The movable carriage includes a handle and a tubular support column which slidably receives a telescopic shaft on which the indexable arms and slidable brackets are supported. The indexable arms and slidable brackets are movable into any desired position to securely hold a bumper during a repair and finishing process. The indexable arms also have a bracket aperture for receiving a slidable cross bracket that is substantially perpendicular to the slidable brackets.

Abstract: A sandblast nozzle is provided with a wear resistant sealing device and a lock-on mechanism. A lever arm is pivotally positioned with respect to a ceramic nozzle. A sealing member is maintained at the end of the lever arm. The sealing member consists of a rubber sealing surface having a wear piece along at least one peripheral edge thereof, that peripheral edge being the first to engage a stream of sand from the nozzle during the closing operation. The wear piece is preferably of hardened steel or ceramic. Square or rectangular seal blocks are employed in the concept of the invention, along with cylindrical seal blocks and discs. Additionally, a lock ring may be maintained upon the sandblast nozzle assembly and rotatable with respect to the axis thereof to engage the lever in an "open" position, to override the biasing of a spring which normally urges the lever to a "closed" position.

Abstract: A valve intended primarily for use on the end of a supply hose for directing and controlling a high velocity stream of an abrasive granular material against an object. The valve has a handle with a usual discharge nozzle mounted on one end thereof, with the granular material supply hose being connected to the other end of the handle. A lever is pivotally mounted on the handle and is movable between open and closed positions with respect to the nozzle. The lever has a hand-actuated inner end portion and a nozzle sealing outer end portion. A spring is mounted on the lever and biases the lever toward closed position. A resilient sealing member is mounted on the outer end of the lever and forms a seal completely external of the nozzle against the open discharge end of the nozzle when the lever is in closed position. Magnets may be mounted on the handle and inner end of the lever and are mutually engageable when the lever is in open position to assist an operator in overcoming the biasing effect of the spring.
