Abstract: Apparatus facilitates the transfer of material from the discharge zone of one mine conveyor onto another conveyor extending perpendicularly to the first conveyor. The transfer apparatus can take the form of a rotatably driven disc disposed beneath the elevated discharge zone of the first conveyor so that the material falls onto the disc. The disc extends over the other conveyor. A scraper lies across the disc to scrape and guide the material into the other lower conveyor. Alternatively, the disc or a modified equivalent component is made stationary while a single scraper or several such scrapers rotate over the disc. The transfer apparatus can also take the form of a curvilinear trough or chute onto which the material falls from the elevated discharge zone of the first conveyor and is guided to the other conveyor. Several driven rollers or paddles or a scraper-chain assembly then impell the material along the chute.

Abstract: A conveyor apparatus for conveying loose bulk material such as gravel and other granular materials from an in-feed location to an out-feed location. The apparatus includes a body for rotating about a vertical axis and a plurality of wings fixedly attached to the body and extending radially outward from the vertical axis. A portion of the wings is positioned substantially adjacent the in-feed location. Another portion of the wings is positioned substantially adjacent the out-feed location. Rotation of the body causes the wings to rotate and to convey the loose bulk material from the in-feed location to the out-feed location.

Abstract: A transport mechanism for articles between a pair of conveyors includes a constantly driven drive member, a driven member and a ball and detent mechanism intercooperating between a pair of confronting surfaces of the members. The transport mechanism is mechanically phased in and out in operation in timed relation to movement of the conveyor to which articles are moved. Mechanical phasing in and out is carried out by a lever having a tooth adapted for engagement in a notch of the driven member and a wheel cooperative with a rail including a gate on the drive member. The transport mechanism is phased out of operation when the wheel enters the gate and phased in in operation when the wheel exits the gate.

Abstract: A conveying device for conveying liquid from a supply well features an upright wall having one major surface and extending into the well, conveying means comprising a disk rotatably mounted about a substantially horizontal axis and a plurality of separations connected to the disk about the axis, the wall abutting the separations, a portion of the surface of the wall, the separations and the disk defining cells for conveying the liquid along at least part of the wall surface, and an output channel defined in the wall and intercommunicating with at least one of the cells when in a position near the top of the disk for emptying liquid from the cells as they reach the position;Whereby, when the disk is rotated, it will move the separations into the liquid and the cells will substantially retain their liquid contents until they reach the position.

Abstract: Disclosed is an automatic sample changer for sequentially operating on a plurality of samples housed in test tubes, circulated around a continuous track, and sequentially associated with a radiation counting device by way of an elevator mechanism. The continuous track is in modular form, and is designed, respectively, to accommodate fifty, one hundred, two hundred or three hundred samples. Rotating index wheels are employed to drive the samples around the track, with several index wheels being used for the longer tracks. The motors controlling the respective index wheels are reversible, and when more than one motor is employed, the motors may be operated in parallel.Also disclosed is a mechanism for loosely coupling the index wheels to their associated motors to facilitate repair and ensure accurate alignment with the plane of the continuous track.

Abstract: A hanger conveying system which routes hangers from a main screw conveyor onto a conveyor branch where they are transported through a processing station and thence returned to the screw conveyor at a point downstream from that where they were initially removed. Included in the conveyor branch is an endless conveyor of hinged links each having a plurality of hanger hook receiving slots or apertures. Also provided is a downwardly inclined input slick rail which picks off hangers from the main screw conveyor, and a cooperating peripherally notched disc which is spaced in close proximity to a curved section of the input slick rail located at the lower extremity thereof. The disc captures, in its notches, hanger hooks which have been picked off the main screw conveyor and are stacked at the bottom of the inclined input slick rail, and individually feeds the captured hangers in spaced relation to an output slick rail which is upwardly inclined.

Abstract: A chain of pivotably interconnected drag buckets for removing material from the sides of a loose pile and for delivering the material to a secondary discharge conveyor. The drag bucket assembly is particularly designed to be pulled about a circular path and includes a forward end adapted to be connected to a towing device and a free rearward end loosely received on a flat supporting surface. As the forward drag bucket is pulled along, the remaining buckets move in the circular path but also migrate radially inwardly toward the storage pile. The buckets scrape along the sides of the pile to remove material and move it along the support surface to openings where the material drops onto a discharge conveyor. The buckets are particularly designed so that flexure along the length of the chain will not cause openings to be formed between adjacent buckets.
