are not in contact with bars 5 referring to fig4 a plural series of link plates 3 can be used instead of a single series of plate 3 in other words more than one link plate can be mounted side by side this arrangement would prevent the chain from breaking apart if one of the adjacent lateral link plates 3 was to break in half referring to fig1 and 3 a pair of guides 19 are mounted laterally opposite each other along the bar 5 bar screws 7 are used to mount guide 19 to bar 5 guides 19 are positioned adjacent to the sides of wheel 1 in order to prevent the chain from coming off of the wheel wheel 1 supports and guides the chain as it circulates about and conveys material referring to fig4 the ends of bars 5 extend out past the edges of link plates 3 to provide a standoff for mounting buckets 17 or external bucket plates 13 this prevents the buckets 17 or external bucket plates 13 from contacting the edges of link plates 3 fig6 shows a conveyor arrangement that is very much improved when combined with the above described new chain this is because the new chain allows for this conveyor to be made simpler lighter faster and more durable than methods of the past these advantages are especially needed when this type of conveyor is used.
