Abstract: A portable truck dump comprises a conveyor system mounted on an elongate frame to transport material from a first end of the frame to a second, opposite end of the frame. A grate is positioned over the conveyor system and is supported by first and second sides of the frame. A ramp extends generally perpendicular to the frame on each side of the frame next to the grate to provide a drive-over access for a material transport vehicle to deposit its load over the grate and onto the conveyor system. A first end of each ramp immediately adjacent to the frame is pivotally connected to the frame to allow the frame to be articulated towards the grate. A second end of each ramp spaced from the frame is supported above but in close proximity to the ground. A support frame is associated with each ramp to provide a barrier along the ground adjacent to and at a level of the second end of each ramp.

Abstract: A conveying system for heavy material such as overburden that contains large rocks as well as small rocks and dirt. The system has a feed system using two blades that rotate over an apron to push material onto the conveyor and a transition assembly between conveyors that lessens the impact of large rock as it drops from one conveyor onto the next conveyor.

Abstract: Method and apparatus for taking up articles wherein the apparatus includes a receiving table with conveyor belts, an auxiliary member located thereabove and a holding assembly located above the article, wherein, for taking up the article, a pressing member of the holding assembly is pressed onto a rearward part of the article from above, and the auxiliary member is pressed against its upper front face, whereupon the auxiliary member is moved upwardly while still pressing against the article, thereby tilting the article about an axis located close to its upper rear edge, thus displacing the receiving table into the gap opening below the article and loading same onto its conveyor belts. The method allows the take up of package-shaped rigid articles, without requiring additional room behind the article and is especially suited for successively handling a plurality of articles located behind each other.

Many improvements are described to make the unloader/reclaimer practical.

Abstract: The apparatus is used for picking up arbitrary, especially heavy, articles. It includes a receiving table and an auxiliary pickup member located above the receiving table. A roller-like pickup member is arranged at the front end of the receiving table for exerting a lifting force to a vertical surface or front face of an article to be picked up. The auxiliary pickup member applies a second, horizontal force to the top side of the article. In this way a torque is generated, which supports tilting and lifting the article.

Abstract: The apparatus and method of this invention safely and efficiently loads and unloads the contents of a load transport container. A manipulator mechanism such as a backhoe having a hemispherical spiked tool at the end of a manipulator arm is mounted on a telescoping conveyor belt system. Right hand and left hand 1/4 turn drive conveyors are used at the front end of the telescoping conveyor belt system to facilitate movement of cargo from the front end of the system to the discharge end. The main conveyor belt has a ribbed design.

The device may be vehicle mounted for simultaneous rotational and translational movement.

Abstract: A leading edge of a web is fed to an upstream cutting station and is gripped at the cutting station with an upstream clamp which is then advanced downstream away from the cutting station to a middle station and is arrested in the middle station where the leading edge of the web is gripped with a downstream clamp and released from the upstream clamp. The leading edge held by the downstream clamp is then moved downstream to a holding station and the opened upstream clamp is moved along the web to a position slightly upstream of the upstream cutting station. The web is then gripped immediately downstream of the upstream cutting station with an upstream clamping conveyor and immediately upstream of the downstream holding station with a downstream clamping conveyor, and is gripped immediately upstream of the upstream cutting station with the upstream clamp.

Abstract: Pieces are cut off the end of a long web by first impaling the leading end of the web on a crosswise circulating needle bar that is then moved downstream from a cutting to a holding section. Then at the cutting station another such circulating needle bar and a noncirculating needle bar are poked through the web, with the noncirculating bar being downstream (relative to the displacement direction of the web) of the circulating bar. Then the web is cut across between the two upstream bars and the noncirculating bar and the downstream circulating bar are dropped down to transfer the piece thus cut from themselves to a transverse needle-chain conveyor. Then the circulating bar is moved back from the downstream holding station to the upstream cutting station while the second circulating bar pulls another piece of the web downstream across above the transverse conveyor.

Abstract: Disclosed is a method and apparatus for lifting and stacking cartons onto a bed attached to a truck bed, especially in an agricultural field. The lifting apparatus includes two endless parallel belts to lift the cartons from the field onto a first conveyor. Variations in carton size or alignment may be accommodated by a pivoting loading frame or by lateral movement of the loader, which lateral movement is compensated for by a self-alignment mechanism. Cartons are transported to an elevator via a first and second conveyor. The elevator lifts the cartons to the level of a palletizer with a false floor wherein a reciprocating and pivoting transfer head removes the cartons from the elevator and deposits them onto the prestacking area of the palletizer false floor. Cartons may be selectively rotated into a transverse loading position by the transfer heads. Upon assembly of a first row of cartons, a tamping bar extends to position the cartons against the truck tailgate or against previously stacked cartons.

Abstract: A travelling hopper belt car has a feed chute and a throw-off conveyor belt that can pivot in a vertical plane around a horizontal axis in the area of the feed chute. The side walls of the feed chute are designed in two parts with the upper side section in each case foldable down around a horizontal axis at least to the height of the axis.

Abstract: A wheel mounted pull type chassis includes a side hitch bar for securement to a tractor or the like. A reel assembly is journalled for rotation and is situated transversely at the front of the chassis and picks up rocks, stones, dirt, etc. and deposits same on an upwardly and rearwardly inclining slotted apron with the teeth of the pick up bars at the reel passing through the apron teeth and depositing the picked up material into a screening wheel journalled for rotation about a generally horizontal but inclined longitudinal axis so that the wheel is tipped rearwardly from the vertical. The periphery of the wheel is slotted. It is supported upon a pair of spaced apart support wheels one wheel of which is driven and which engage a track around the outer periphery of the wheel. Three equidistantly spaced rear support wheels engage the rear of the periphery of the wheel for added support.

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.
