Endless chain conveyor link

A plate top conveyor chain apparatus comprising

• an endless chain having a plurality of yoke links forming operative components thereof,
• each of said yoke links being of inverted channel shape, having a web portion adapted to support a plate top mounted thereon.
• side flanges right-angularly extending from the side edges of said web portion,
• and a pair of feet right-angularly oppositely outwardly extending from the distal ends of the side flanges,
• a wear pad having right-angularly related portions engaged respectively with the outer surface of each yoke link side flange and the adjacent surface of its foot,
• and means removably securing said wear pads to said yoke links, said means comprising
• interfitting pin and socket means on the yoke link side flanges and the portions of the wear pads engaged therewith preventing rise of the pads from the yoke links, in combination with tabs upstanding from the feet of the yoke links and penetrating sockets in the portions of the wear pads engaged therewith preventing movement of the wear pads outwardly from the yoke links.

• side flanges right-angularly extending from the side edges of said web portion, and a pair of feet right-angularly oppositely outwardly extending from the distal ends of the side flanges,
• a plurality of removable and replaceable wear pad units formed of flexible resilient plastic, each having two right-angularly related portions, comprising a first portion engaged with the outer surface of a yoke link side flange and a second portion engaged with the upper surface of the adjacent foot of said link,
• and means mounting said wear pad unit on said link,
• said mounting means comprising a tab upstanding from a foot of the link and penetrating a socket in the under surface of said second portion of the unit so as to prevent movement of the unit outwardly from the link,
• and said mounting means including also a second separation preventing means comprising means holding said first portion of the unit against rise on the link,
• whereby said wear pad unit is mountable by snapping its socket over the adjacentlink foot tab and is removable by deforming the second portion of the unit to lift the socket in said portion free of the tab for movement of the unit outwardly from the link without rise of said first portion of the unit on the link.
