Abstract: An improved adjustable conveyor belt has a plurality of modules having intermeshing link ends extending lengthwise. The modules are connected together by connecting pins extending widthwise through holes formed in the link ends. Each of the modules also has side edges and a slot adjacent to each of its side edges. Thus, slots are provided along the side edges of the belt regardless of the arrangement of the modules. A stop, removably fitted into slots located along the side edges of the belt, prevents widthwise movement of the connecting pins. The stop has a guide mechanism for guiding the stop into the slot, an end portion which extends into the pin insertion hole, an engaging portion which engages a tongue formed in the slot, and a protrusion which snaps into the pin insertion hole. This configuration makes it easy to assemble, add to, and dismantle the conveyor belt, without substantially increasing the size or weight of the assembly.

Abstract: A flat top conveyor chain comprising a plurality of flat top links, each link having flat top surface for carrying articles. The links are chained by means of connecting pins to form a conveyor chain. The flat top link each are made from a polyacetal resin material having a long chain alkyl ester based lubricant therein.

Abstract: In a conveyer for articles comprising two chains running in parallel to each other, articles are supported by rollers rotatably supported on rods having pins at their ends which pivotally connect the adjacent links of the chains. The conveyor structure is light in weight, and damage to rollers is avoided because rollers on adjacent rods cannot contact each other as the return run travels over convex supporting plates. On each chain, link plates of either the inner or outer links, on the side of the chain adjacent to the rollers, are formed with outwardly projecting flat surfaces which are substantially at the same height as the article carrying peripheral surfaces of the rollers. These outwardly projecting flat surfaces allow convenient lateral transfer of articles from one conveyor to another by means of transfer guides.
