  • Patent number: 4858978
    Abstract: The invention is directed to a coupling arrangement for changing a compon on a block of a hoist which is fitted with a rotary drive. The coupling arrangement has an upper part which remains on the block and which has a latching mechanism for accommodating a lower part. Each tool or component which is to be coupled to the block has a lower part which can be coupled and latched together with the upper part so that by changing the lower part, it is possible to change the component. In order to achieve a reliable and rapid remote exchange of a component on a hoist, the upper part is configured as a hollow cylindrical part which is provided with a bottom wall. The bottom wall has a central aperture from which extend two radial slots. The hollow cylinder and the lower wall conjointly define a housing for the latching mechanisms which are disposed at about 90.degree. in relation to corresponding ones of the radial slots.

  • Patent number: 4858998
    Abstract: A wheel supporting assembly for a motor vehicle, comprising a wheel carrier member (1) with means for attachment to at least one suspension component, and a unit of hub member (16), universal joint member (21), and bearing with outer race (15) integral with or received in a bearing housing (3), secured to the wheel carrier member. The wheel carrier member affords a formation (2) open and undercut-free in a direction transversely of the rotational axis of the hub member, so that the hub member-bearing unit can be fitted radially to the wheel carrier member. The bearing housing of the unit is then held to the wheel carrier member by at least two fixing elements, particularly bolts, spaced from one another by a distance greater than an outer diameter of the bearing, which distance is preferably less than the size of a flange on the hub member to which a wheel is to be attached.

  • Patent number: 4850492
    Abstract: An ejection station for a conveyor sorter having a carrousel ejector wheel with reciprocating fingers. The ejector wheel has a front side mounted adjacent the edge of the supply conveyor belt. The bottom of the wheel moves at substantially the same speed as the belt and in the same direction. The ejector fingers are mounted around the outer surface of the wheel and move axially out of the front side over the conveyor belt to eject items from the belt. Operation of a finger is initiated when the nib of the finger enters a V-shaped guide groove. As the wheel rotates, the nib moves along one leg of the "V" pushing the finger out. At the middle of the groove, the direction of the finger reverses and the nib moves along the other leg of the "V" retracting the finger into the wheel.
