  • Patent number: 4427333
    Abstract: A vehicle having a body for receiving trash or other material from a container is fitted with a loading arrangement which lifts the container from the ground, raises the container and tips it to dump the contents into the vehicle body. The loading arrangement includes an upright mast assembly attached to the vehicle, a container engaging device mounted on the mast assembly for guided movement therealong and a drive mechanism for raising and lowering the engaging device, the drive mechanism including an articulated linkage having a lower end pivotally connected to the engaging device for movement about a horizontal axis. The upper end of the linkage is mounted for swinging movement about a second horizontal axis. A power device is connected to the upper end portion of the linkage to swing the latter in a vertical plane transverse to the vehicle axis.

  • Patent number: 4408946
    Abstract: The application discloses a design for an automatically dumping hopper for use with a forklift. The hopper is designed for a 1-man operation with the operator transporting stacking and dumping the hopper without leaving the forklift seat and without the use of any controls other than the controls of the forklift. Two embodiments of the invention are disclosed. One embodiment which is useful for sand, gravel and other loose bulk material has a hinged bottom secured to the sidewalls with a hasp latch constructed such that when the hopper is tilted on edge, the hasp clears from its retainer, releasing the bottom to open when the hopper is lifted. The latch only releases upon tilting of the hopper so that the hopper can be transported and stored when lifted vertically.

  • Patent number: 4403901
    Abstract: A dump bin having a housing including a floor and a plurality of upstanding sides, a sleeve vertically mounted on one of the sides, a slidable rod in the sleeve, a pair of aligned shafts extending outwardly from opposite sides for receiving bearings mounted on the forks of a fork lift, the slidable rod being movable by gravity from a retracted position to an extended position below the dump bin after it has been lifted by a fork lift, with the lower portion of the rod causing the dump bin to pivot about the axis of the shafts as the fork lift is moved toward the container after the slidable rod has been moved into abutting relationship with the container.

  • Patent number: 4334820
    Abstract: A bucket system incorporating a tilting mechanism comprises a pair of horizontal arms each provided integrally with a pair of stanchions having an arcuate bend in the upper portion thereof and having one or more pulleys disposed at the leading end of the arcuately bent upper portion, a bucket rotatably fastened to the pair of horizontal arms, and a pair of cables fastened at one end thereof to the lower end of the rear side of the bucket, passed over the pulleys on the stanchions, and again fastened at the other end thereof to a stationary mast on the fork lift, whereby elevation of the two-pronged platform of the fork lift whose two prongs are inserted into and held within the pair of horizontal arms causes the cables to stretch to their full length and thereby draw up the lower end of the rear side of the bucket so as to tilt the bucket as a whole and de-elevation of the two-pronged platform from its elevated position causes the bucket to return to its original horizontal position.

  • Patent number: 4306707
    Abstract: A machine for raising and lowering molds while maintaining the mold components together to prevent the contents from escaping. An upright frame is equipped with caster wheels and a winch which winds up a pair of cables attached to a harness. The harness is applied to the mold and includes a pair of opposed plates on opposite sides of the mold. Straps are extended through eyes presented on the plates and are passed around the mold in a crossing pattern and tightened to hold the mold components together. The cables have looped ends which are received by pins projecting outwardly from the plates of the harness.

  • Patent number: 4286913
    Abstract: An improved apparatus for collecting, storing, transporting and dumping cropped (cut) sections of continuously cast bar. The present invention is embodied in a dumpable crop bar container generally comprising a yoke and rear stanchion assembly surrounding and pivotally attached to a receptacle and front stanchion assembly by an axle and sleeve assembly. A conventional forklift is used to transport the present invention and to discharge collected crop bar from it. The forklift pushes the front stanchions against a stationary curb, forcing them to pivot inward and upward on the axle which cause the receptacle rigidly affixed thereto to pivot upward and outward. The base of the receptacle pivots to almost vertical and all of the crop bar is dumped out. As the fork lift backs away from the stationary curb, the weight of the receptacle and front stanchion assembly returns it to its original position.

  • Patent number: 4175903
    Abstract: A pick-up apparatus and a container are specially designed to facilitate the lifting of the container and the dumping of its contents. The container includes a frame which has tubular frame members extending between the top and bottom of the container, and a cover is hingedly mounted on the top of the container and can be releasably latched in a closed position by an inertia latch. The pick-up apparatus includes a boom, a pick-up arm mounted on the boom for articulation in a generally horizontal plane, and a pair of clamping arms mounted on the end of the pick-up arm. The clamping arms are slidably mounted on the pick-up arm, and the spacing between the arms can be varied by hydraulic cyinders on the pick-up arm. Each of the clamping arms includes a clamping pad which includes a plurality of flexible, resilient cone-shaped projections which are sized and spaced so that the tubular frame members of the container can be received between the ends of adjacent projections.
