Abstract
The specification discloses a snap-on top plate assembly for a roller chain. The assembly comprises an inside saddle in the shape of a channel, an outside saddle in the shape of a channel shaped to fit over the inside saddle, and a top plate. The inside saddle has holes through its legs shaped and positioned to accept the outside ends of the pins in a link of roller chain when the link is positioned within the inside saddle. Three embodiments are disclosed. In two of them, the legs of the inside saddle are generally flat; in the other, the legs of the inside saddle are bowed inwardly.
