Patents by Inventor Hudson Stewart

Hudson Stewart has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4289089
    Abstract: The applicator includes two elongated conveyor rollers arranged in parallel alignment and inclined from a sealant application station toward a tire unloading station. The rollers simultaneously rotate a series of tires in the same direction about a common axis in side-by-side engagement with one end tire adjacent the sealant application station and the other end tire adjacent the unloading station. A kicker assembly unloads the latter end tire, whereupon the rollers advance the remaining tires toward the unloading station while maintaining coaxial rotation thereof. A fresh tire then may be positioned at the application station and the application and advancement steps repeated. The applicator further includes a sealant applicator for effecting airless spray application of sealant to a tire, together with a control system for controlling the position of the spray applicator and causing sealant to be purged a predetermined time after no sealant application is made.

  • Patent number: 4272301
    Abstract: The cleaner includes an elevator for moving a tire vertically toward a stationary cleaning head which is made up of spreader rollers for spreading the tire beads a sufficient distance to admit a powered cleaning brush, along with cleaning fluid application and removal apparatus, into the tire interior during such tire movement. The elevator further supports and rotates the tire with respect to the brush during cleaning while the spreader rollers, together with additional fixed guide rollers, maintain the tire vertical and in alignment with the brush. The elevator lifts each tire from a horizontal conveyor which alternately discharges a cleaned tire and receives a fresh one. During cleaning, the brush is movable transversely along an arcuate path within the tire interior at selected contact pressure and is driven alternately in opposite directions. The cleaner is suited for usage in a system for producing self-healing tires.
