To adjust the tension in the chain a motor is operated to drive a self-locking worm gearing which employs a worm wheel meshing with a rack fixed to the machine frame and extending in the direction of the chain.

Abstract: A large round baler is equipped with a pick-up and a feed fork apparatus which work together to gather crop from the ground and deliver it to the inlet of the bale forming chamber of the baler. The feed fork apparatus includes a plurality of teeth which are mounted to an eccentric located beneath a chute of the apparatus and are caused to sweep along an oval path in the direction of desired crop movement, the tines moving through respective slots provided in the chute. Leading edges of the tines are stair-stepped so that they engage the crop and carry it along the chute to the inlet to the bale forming chamber.

Abstract: Apparatus for gathering particulate material in mines and similar plants has a mobile platform which collects particulate material and surrounds the trailing end of a material removing conveyor. The sides of the trailing end of the conveyor are flanked by plate-like carriers on each of which are fixed several beams serving to push gathered material toward and onto the conveyor in response to movement of the carriers toward the conveyor. The carriers are movable toward and away from the conveyor by motors which are installed beneath the platform, and the apparatus further employs stationary or reciprocable barriers, one behind each beam, which prevent the beams from pushing material away from the conveyor during return strokes of the carriers. Those ends of the beams and barriers which face in the direction of forward movement of the platform slope forwardly and downwardly to facilitate penetration beneath the accumulations of particulate material on the platform.

Abstract: A transfer station from a longwall chain conveyor to a drift chain conveyor have upper and lower reaches which cross alternately. The upper belt section of the longwall conveyor comprises a scraper over the upper belt section of the drift conveyor. The working face side of the longwall conveyor has a plane guide for a coal plane and a plane chain which at least at the drift-side end of the longwall conveyor is guided via guide wheels to a gob-side drive unit. These two drift-side guide wheels are arranged with a vertical spacing from each other in the lower belt section of the longwall conveyor such that they form between them a passage for the chain belt and for the tappets of the longwall conveyor attached thereto. The drift-side guide wheels are arranged so close to the drift conveyor that in its drift-side and position the coal plane can transfer the won coal directly into the drift conveyor. In all, an especially compact plane chain deflection integrated into the longwall conveyor is realized.

Abstract: Apparatus for retrieving round hay bales includes a frame, an elongated, rigid and generally U-shaped pan supported on said frame and a generally U-shaped bail. A pair of carriages are slidably supported on the pan and the legs of the bail are pivoted to the carriages. An endless driven chain shifts the carriages and the bail longitudinally of the pan. A drive operatively engages the bail to pivot the bail through an angle of approximately 180.degree.. The frame is tiltable so that a forward open end of the pan may be positioned at ground level immediately adjacent a round hay bale. The U-shaped bail may be disposed around the hay bale and the carriages shifted so that the hay bale is pulled onto the elongated pan.

Abstract: A self-contained, moveable material handling apparatus is characterized by a chassis having a material conveyance surface mounted for rotation with respect to the central vertical axis thereof. A deck is also mounted for rotation with respect to the chassis, independently of the material conveyance surface. A loading boom, having a loading device on the end thereof, is mounted to the deck for rotation about the central vertical axis of the chassis. The boom is also pivotable about a horizontal axis and extendable and retractable along its own axis. The loading device and the boom cooperate to load material from the interior of a carrier onto the material conveyance surface. The surface rotates the material until it is deflected from the surface by a deflector conveyor onto a carry-off conveyor. The speed of the material conveyance is less than the speed of the deflector conveyor, which speed is less than the speed of the carry-off conveyor.

Abstract: Crank-operated rods are mounted on two vertically spaced apart crankshafts, which are driven to rotate in the same sense. Working tools are carried by said rods on the side thereof which faces the body of silage and penetrate said body as they move downwardly. Each crank-operated rod is provided at its lower end with at least one depending conveying tine, which at least during part of the movement of the respective crank-operated rod away from the body of silage moves over a bottom plate, which extends under all juxtaposed crank-operated rods and is trough-shaped on the side that faces away from the working tools.

Abstract: A conveyor is composed of a series of L-shaped sections arranged end-to-end to define a conveying floor surface with a side wall at one side opposite the mineral face so as to allow material to fall onto the floor surface. The side wall has a slot or gap therein through which extends entrainment devices capable of extending across the floor surface or being stowed inwards towards the side wall. Where the conveyor is constructed as a shuttle conveyor the entrainment devices are allowed to pivot automatically between these alternate positions as they are driven back and forth along the floor surface by a reciprocating traction means. The traction means runs outside the side wall and the devices are pivotably mounted to the traction means which preferably also performs a guide function.

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 axis of apron-conveyor pivotal mount is removed from the center of rotation of the front end of the conveyor and spaced rearwardly and downwardly therefrom. The distance between the rear apron edge and the axis of apron-conveyor pivotal mount is greater than the distance between the said edge and the center of rotation of the front end of the conveyor. The axis of apron-conveyor pivotal mount is disposed in a transverse vertical plane which is positioned between the rear apron edge and the center of rotation of the front end return portion of the conveyor.

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.

Abstract: A loading and conveying machine has crawler treads and a frame extending substantially forwardly thereof. A conveyor is mounted for pivotal movement about a horizontal axis and extends rearwardly from ahead of the frame to the back 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 machine has an approach angle providing a space defined by a ground plane and a forwardly and upwardly inclined plane tangential to the arc described by the front of the treads and extending through the lower front frame corner. The apron is angularly adjustable, and furthermore, the apron pivot is vertically shiftable to thereby change the apron attitude so that it can be wholly positioned above the inclined approach plane without obstruction by the conveyor.
