  • Patent number: 9415939
    Abstract: A chain driven by two sprockets spaced a short distance apart along their common axial centerline. The chain includes elongated pins that extend beyond the outer surfaces of the chain link plates, on both sides, by a distance about equal to the width of the spaced apart sprockets. The chain is aligned midway between the sprockets, and the sprocket teeth drive on the extended portion of the chain pins. Where a flight is attached to the chain links, the pins are extended still further, to fit into the indentations or holes in the flights. This provides an exposed length of each pin in alignment with the sprocket on each side for driving purposes. The chain has a piece extending between the plates to reduce the likelihood of a pin extending further outside of one side plate or the other. A shoulder on the pin further reduces the likelihood of this happening.

  • Patent number: 8770388
    Abstract: A sweep conveyor extends along a bin floor between a sump pivot about which the conveyor rotates, and an outer end adjacent the bin wall. During the conveyor's orbit about the floor, flights at the conveyor bottom sweep across the floor toward the sump pivot, whereby bin material in front of the conveyor is swept into a sump. The conveyor is preferably made in modular sections connected end-to-end, whereby different sections are combined to construct conveyors having different lengths and capabilities. Some sections are preferably hinged together, allowing different sections to adopt different inclinations as they travel about a non-level floor. The flights are preferably provided on a belted chain riding on sprockets at opposite ends of the conveyor, and the chain is not supported by idler sprockets along its length, allowing the chain (and its flights) to sag under gravity so the flights ride along the bin floor.

    Abstract: An elongated drawbar tension element is provided for the conveyor chain of an en masse conveyor. The drawbar includes a hollow hub at one end for receiving an enlargement at the other end of an adjacent drawbar element coupled thereto to form a chain. The side faces of the hollow drawbar hub are formed with tapered dovetail shaped grooves for receiving complementary tapered dovetail shaped tongues formed on the inboard sides of transversely extending conveyor flights. The tapered tongue and groove connection is self-tightening in normal use and the complementary dovetail configuration thereof prevents lateral separation of the conveyor flights from the drawbar hub. An adhesive material may be applied to the self-tightening connection to prevent loosening thereof and separation of the flights from the drawbar elements when the conveyor chain is subjected to vibration, irregular loads or is moving in a downward direction.

  • Patent number: RE35555
    Abstract: In an automatic loading system and method wheeled carts receive five or six layers of newspaper bundles of four to six bundles per layer. A waist-high conveyor and an inclined ramp conveyor move bundles to a roller platform of independently operated roller sections selectively halted upon receipt of a bundle. When the desired number of bundles have been delivered to the roller platform, a pusher laterally moves the bundles to a split roller platform. A second group of bundles are delivered to the roller platform and the split roller platform. The sections of the split roller platform are then abruptly pulled apart causing the bundles to drop upon a fork-like platform extending into one side of a cart receiving the bundles. The pusher is retracted to the start position and the fork-like platform is lowered to receive the next layer of bundles in a like manner.
