(under subclass 422) Devices in which the elevating and inverting means comprises a plurality of receptacle suspending cables, all or some of which may constitute the means for elevating the receptacle, and certain one or ones of which may be moved relative to or at a speed different than the others to invert the receptacle.
(1) Note. Since no specific home is provided in Class 254 for differentially operated hoist cables cooperating to rotate as well as elevate a load, patents showing such cable arrangement for dumping the contents of a receptacle but not claiming the receptacle-engaging means are included here.
SEE OR SEARCH THIS CLASS, SUBCLASS:
560+, for miscellaneous cable arrangements adapted to rotate as well as elevate a load, other than a receptacle, to orient it.
639+, for elevator or hoist type devices in which the load carrier is tilted by differentially operated cables.
