Patent number: 4304516Abstract: A solid waste disposal system employs solid waste transport trailers adapted to be towed by a tractor. The trailers each comprise a closed body of a generally rectangular cross-section having a bottom, side and top walls, a forward end wall and a rear end wall. The top wall proximal to the forward end wall is provided with a loading neck through which solid waste can be loaded. The rear end wall is a door hinged at the rear edge of the top wall and is adapted to be closed during the loading operation and transport of the solid waste and opened for the unloading of the solid waste. A conveyor is located adjacent the bottom wall of the trailer and extends substantially over the entire length of the bottom wall. The conveyor is operable during loading and unloading to move the solid waste in a direction from the forward end wall toward the rear end wall. The trailer is supported by ground wheels with tires, the wheels being low pressure flotation tires to facilitate the use of the trailer on landfill sites.Type: GrantFiled: June 4, 1979Date of Patent: December 8, 1981Assignee: Waste Management, Inc.Inventors: Howard A.

Patent number: 4263851Abstract: A mobile ballast cleaning machine comprises a frame running on two undercarriages a rear one of which is supported on a track section resting on cleaned ballast. A ballast excavating and conveying chain is mounted on the frame in front of this track section and a ballast screening mechanism on the frame receives the excavated ballast from the chain, cleans it and discharges the cleaned ballast to a storage receptacle arranged on the frame between the undercarriages. The storage receptacle has sufficient capacity to hold a volume of the cleaned ballast corresponding to that of the excavated ballast and a rising ballast conveyor is mounted in the storage receptacle for distributing the cleaned ballast therein. The cleaned ballast is discharged from the storage receptacle for redistribution by a ballast conveyor system and devices for regulating the flow of the cleaned ballast and for guiding the same between the discharge from the receptacle and the ballast conveyor system.Type: GrantFiled: February 21, 1979Date of Patent: April 28, 1981Assignee: Franz Plasser Bahnbaumaschinen-Industriegesellschaft m.b.H.Inventors: Josef Theurer, Karl Folser

Patent number: 4241653Abstract: Bank out module builder with unloading mechanism having a generally rectangular framework formed by spaced apart sidewalls and spaced apart front and rear walls with the top and bottom being open, the rear wall being formed by a door being movable between open and closed positions. Ground engaging wheels are carried by the framework to facilitate movement of the framework over the ground. A bottom structure is secured within the lower extremity of the rectangular framework for closing the bottom side. A carriage is mounted in the framework for movement longitudinally along the framework between the front and rear walls. A tramper mechanism is carried by the carriage and is movable vertically in the framework for tramping material introduced into the rectangular framework through the top side to form a module within the rectangular framework.Type: GrantFiled: February 12, 1979Date of Patent: December 30, 1980Inventors: John L.

Patent number: 4241879Abstract: A novel drive system for a manure spreader is disclosed wherein an infinitely adjustable variable speed drive mechanism transfers power from the power input shaft to the apron assembly and a constant speed drive mechanism transfers power from the same power input shaft to the beater assembly. A bypass mechanism allows for an extension of the hydraulic cylinder controlling a cam device, used for varying the speed of the apron drive mechanism, without activation of the cam device when the power input shaft is not engaged for rotation of the drive system. A tensioning idler connected to the cam device through a lost motion linkage provides for disengagement of the beater drive system during the cleanout of the manure spreader by the apron assembly. A drive shaft to the beater assembly is included inside of a tubular drive shaft to the apron assembly, whereby a concentric drive line assembly transfers power rearwardly to the driven assemblies.Type: GrantFiled: February 2, 1979Date of Patent: December 30, 1980Assignee: Sperry CorporationInventor: William F. Ostergren

Patent number: 4195958Abstract: A bale unroller for unrolling cylindrical bales of hay. A boxlike container has a side door for insertion of a bale of hay onto an elevated and inclined floor. A plurality of angle irons extends transversely across a floor and are connected at ends by chains which are in turn driven by sprockets. As the sprockets are driven, the angle irons slidably move along the floor to impart rotative movement to the bale. A plurality of rollers, horizontally disposed above the floor at the discharge end of the unroller, limit forward movement of the bale. A pair of wheels, which are pivotally supported by a framework, urge the bale forward to keep it in contact with the rollers. The sheet of hay, which is removed from the bale, is fed from the unroller by a lower roller and by a paddle conveyor. Methods of unrolling a cylindrical bale are also provided.Type: GrantFiled: May 30, 1978Date of Patent: April 1, 1980Inventors: Vernon F. Vahlkamp, Wayne Diekemper

Patent number: 4160619Abstract: A mine haulage vehicle comprising a body having front and rear sections which are pivotally interconnected at adjacent ends enabling them to swing freely in a horizontal plane relative to each other about a vertical pivot axis. The body has a pair of ground-engaging wheels on each of the body sections. The vehicle is steered by hydraulic cylinders connected between the body sections for swinging them about the pivot axis. The body sections have aligned trough-shaped compartments extending substantially its full length and containing a horizontally flexible, center strand, orbital, chain conveyor. The rear body section has a load-carrying compartment above the conveyor and has upstanding push blades on opposite sides of the conveyor with power cylinders to move the blades inwardly and to transfer material onto the conveyor during unloading.Type: GrantFiled: November 4, 1977Date of Patent: July 10, 1979Assignee: New River Manufacturing Company, Inc.Inventor: Robert C. Nelson

Patent number: 4149642Abstract: A refuse compacting mechanism is provided in the container of a refuse wagon. The mechanism includes a series of bars transversely oriented on the floor of the container and a pusher mechanism at the rear of the container. Uncompacted refuse falls into the container rearwardly of the bars and is pushed toward and compacted against the rearmost bar by the pusher mechanism. As additional refuse is added and compacted, the previously compacted mass topples forwardly over the rearmost bar to be further compacted against the next bar. Preferrably, the bars are connected to endless chains and may be moved rearwardly in unison to aid in unloading compacted refuse from the container.Type: GrantFiled: October 21, 1977Date of Patent: April 17, 1979Inventor: Willi Schneider
