Abstract: In a loading device with a loading platform for receiving mined material, wherein the loading platform is swept over by loading arms and the material is conveyed onto a conveying device connected to the loading platform, the loading arms are designed as arms of a rotatably mounted loading star-wheel, and a plurality of loading star-wheels are arranged over the width of the loading platform.

Abstract: A silo unloader having a framework and concentric oppositely driven rings with oppositely acting plows to shift particulate material in a silo to a central discharge defined by vertically spaced plates. The rings are driven by compressible rollers such as pneumatic tires, compressed between rings and powered by electric motors. Additional compressible friction rollers engage the wall of the silo in a vertical rolling action to guide vertical movement of the unloader and resist rotational movement of the framework which is suspended on cables.

Abstract: A movable continuous bulk material conveyer, especially for unloading ships. A steep-rise conveyor is provided that comprises a conveyor belt and a cover belt. The bulk material is thrown by two casting reels into the lower gap between the conveyor belt and the cover belt. Since during the meander-like removal of material from the hold of a ship, the position of the casting reels and the steep-rise conveyor relative to one another constantly changes, the shafts of the casting reels are pivotably connected via a quadrilateral articulation with the lower guide pulleys of the steep-rise conveyor, and are controlled by hydraulic pistons from a computer in such a way that the casting reels always pick up a constant stream of bulk material and throw this material in the direction of the angle bisector of the gap of the steep-rise conveyor.

Abstract: This is a combine conveyor apparatus having a combine auger conveyor apparatus of this invention mounted on a conventional combine structure. The combine auger conveyor apparatus includes a feeder auger conveyor assembly which transfers cut wheat or the like to a feeder slat conveyor assembly which, in turn, conveys the cut material into a threshing cylinder assembly. The feeder auger conveyor assembly is known in the prior art having spiral flights on a cylindrical support driven to move the material to the center thereof and having a central auger retractable finger assembly to move the material into the feeder slat conveyor assembly. The feeder slat conveyor assembly includes a first sprocket assembly connected by a feeder chain and slat assembly to a second sprocket assembly.

Abstract: A coal-gathering assembly for a continuous miner in which a platform is disposed behind a rotatable cutter, and a coal-transporting conveyor is located adjacent the platform for delivering coal rearwardly of the miner. The assembly includes a base plate rotatively mounted on the platform on each side of the coal-transporting conveyor. A plurality of bars are carried by each base plate, each bar extending across its associated base plate intermediate the rotative axis of the base plate and the base plate periphery. Each bar has one end adjacent the next angularly adjacent bar and has the other end extending beyond the base plate periphery. Each angularly adjacent pair of bars provide a substantially inwardly closed pocket. More particularly, each bar extends across the base place and is spaced from and intermediate the rotative axis and the base plate periphery, and extends substantially transverse to a radial line passed through the rotative axis and intermediate the ends of the bar.

Abstract: A gathering platform extends forwardly from the front end of a mixing machine and has an upper surface in which a pair of counter-rotating gathering discs are rotatably mounted. Each disc is rotated to move mined material centrally and rearwardly on the platform upper surface toward a material guide that extends rearwardly in overlying relation with a portion of each of the gathering discs to the receiving end of a longitudinally extending conveyor. A plurality of radially extending slots extend through each disc, and a material gathering arm is positioned in each slot. One end of each arm is connected to rotate with the gathering disc. The opposite end of the arm rides on a cam surface in the gathering platform. The cam surface has a first portion and a second portion. The second portion is positioned at an elevation below the first portion and beneath the material guide.

Abstract: An improved rotating disc-type gathering head suited for use with underground mining machines includes at least two gathering discs mounted for rotation on an inclined apron in positive engaging relationship at their point of tangency. One of the discs is rotatably driven, preferably by means mounted above the apron. The second disc is rotated in the opposite direction by the first disc to provide the desired flow of mined material. In the preferred embodiment the discs have peripherally disposed intermeshing gear teeth, and the drive means comprises a pinion gear in peripheral engagement with the first disc. Additional gathering discs can be added without complicating the simple mechanical drive system below the apron.

Abstract: This invention pertains to an arrangement for conveying, handling and storing of solid bodies, bulk material, jelly products or liquids, which arrangement characterized by a plurality of rotary shafts arranged at a distance apart from each other, each of said shafts being equipped with one or more cams, the distance between adjacent shafts being approximately equal to or greater than the length of the cams.

Abstract: A riding toy vehicle for picking up objects from a playing surface such as the floor, comprises a vehicle body having a seat, an open mouth adjacent the forward end and a bottom wall rearward of the mouth for holding the objects as they are picked up. A pair of front and rear wheels are provided for supporting the body for movement over the playing surface and a pair of pick up members are mounted for rotation in the mouth and are driven independently by the front wheels for engaging the objects on the playing surface and moving them upwardly onto the bottom wall of the body through the open mouth. A deflectable tongue is provided to extend downwardly towards the bottom wall for retaining the objects that are picked up once they are positioned on the bottom wall in the vehicle body.

Abstract: A loading and conveying machine has crawler treads and a frame extending forwardly thereof. A conveyor extends from the front to the rear of the machine. An apron is pivotally mounted at the front of the frame and receives material from a loading implement and deposits it onto the conveyor. The front end of the conveyor is pivotally mounted to the apron and arcuately moves about the apron pivot axis when the apron is raised or lowered. The joined conveyor and apron may also be adjusted together by vertically moving the apron pivot axis. The midsection of the conveyor is articulated so that the conveyor framework is separated into front and rear segments which are independently movable relative to each other and to the machine frame.
