  • Patent number: 5487635
    Abstract: The warehouse has a high storage density and is suitable for the storage of bulk goods. The warehouse has at least three superimposed storage areas. A storage area is laid out as the operational level for the storage and withdrawal of the goods. A further storage area consists of a storage level with one or more superimposed storage levels for storing and consigning goods. A further storage area is used as an auxiliary operational level for preparing roller pallets and taking them to the operational level.

  • Patent number: 4142349
    Abstract: A mower with two pairs of counterrotating cutting disks has a frame on which two yokes are mounted for independent swinging about a horizontal axis transverse to the direction of travel, each yoke carrying a pair of coacting horizontal conditioning rollers which in a working position lie in the wake of a respective disk pair to gather and press the mown crop coming from these disks. The conditioning rollers are driven from a pair of ancillary shafts on the machine frame, operatively linked with the disk drive, through extensible and universally jointed transmission shafts enabling each yoke to be separately swung into a retracted position.

  • Patent number: 3975892
    Abstract: A haying machine has a plurality of rotary rakes spaced apart transverse to its travel direction. Each rake has a plurality of tines extending through a housing rotatable about an upright axis and each having an inner end secured in a ball rotatable about an element nonrotatable in the housing but axially displaceable therein. The times each have an upper section about which they may be twisted by cam action, and a lower section that normally extends at a right angle to the ground. When the element in which the balls are carried is lifted all the way up control arms on the rake elements ride a cam to orient these elements with respect to the ground with the orbits of adjacent rakes spaced from each other, and when this bearing plate is lowered the control arms are moved out of contact with the cams in the housing and the rake elements are lifted so as to define an orbit of larger diameter that overlaps with the orbit of the neighboring rake.
