    Abstract: A palletizing machine and method which are particularly applicable to high-speed loading of cases in tiers on pallets or sheets in that every case received at the tiering operation and which requires repositioning is contacted by a case orienter and conducted to a scheduled relative position to ultimately form the desired tier or layer pattern without stopping forward motion of any part of any case at any time. In addition, the tiers so formed are alternately stacked without overhead suspension directly from the stripper plate onto two separate pallets or sheets.

    Abstract: The present invention relates to endless conveyors frequently used for carrying objects overhead and of the enclosed track type in which the track is a four-sided box in cross section usually square or slightly rectangular. The trolleys which run inside the track are alternately provided with vertical wheels and horizontal wheels considered when the track is running horizontally. Hooks extend from the vertical wheel trolleys through a slot formed usually in the bottom section of the track and support the objects conveyed. The horizontal wheels contact one or the other of the vertical sections of the track and eliminate excessive rubbing friction between the trolleys and the track. The horizontal wheel trolleys are provided with at least two horizontal wheels positioned one after the other or in tandem in the direction of the trolley travel for sequential contact with the track which on horizontal curves cause the ends of these trolleys to move away from the convex side of the curved track on the inside of the track, which action forces each vertical wheel trolley connected between two two-wheeled trolleys to be bodily moved away from and held out of contact with the convex side which eliminates all rubbing friction completely.

    Abstract: This invention relates to an article handling conveyor of the accumulation-type which means that whenever an article is stopped from movement thereon, the article following is automatically also stopped at a point where it can not exert any sizeable force against the first stopped article and this action is repeated as additional articles approach stopped articles ahead. This makes it impossible for the articles to damage each other because of the lack of pressure exerted from one to the other and also prevents pressure from building up as the line of articles lengthens. It also make it possible to remove an article from the line without a struggle. The power source is a constantly moving beltlike member or band from which power is taken off to move the articles and released to stop the articles. The power takeoff and release mechanism is characterized by its ability to operate without ever disturbing the position of the band laterally of its normal path of movement which reduces wear on the band, enables it to run smoothly, reduces noise, and does not disturb the tracking of the band.
