Abstract
A conveyor system has a track defining an endless path traversing a loading station and an unloading station and having a transport stretch therebetween, an annular succession of longitudinally spaced trucks riding on the track, and an endless conveyor belt extending along the track and having a pair of longitudinally extending edges one of which is suspended from every other truck and the other of which is suspended from the remaining trucks. A drive element extends along the track and engages the trucks to advance the belt in a longitudinal transport direction from the loading station through the transport stretch to the unloading station and then back to the loading station. At least one carrier is connected to the lower end of at least one hanger having an upper end releasably attachable to the belt so as to suspend the carrier from the belt in the transport stretch. The carrier can be a flat rigid pallet having corners each connected to the lower end of a respective such hanger. It can also be an upwardly open material-carrying vessel similarly having corners each connected to the lower end of a respective such hanger or a simple skilift-type chair suspended from a rigid hanger, a system which makes it very convenient for individuals to move along the often very long transport stretch in a mine.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
