Abstract
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.

Claim 1
Independent Claim
219 words
A snap-on top plate assembly for a roller chain, said assembly comprising: (a) an inside steel saddle in the shape of a channel having a base and two upstanding, inwardly bowed legs, the legs having holes therethrough shaped and positioned to accept the outside ends of the pins in a link of roller chain when the link is positioned within said inside saddle, said inside saddle being made from a relatively but not totally inflexible material; (b) an outside steel saddle in the shape of a channel having two upstanding legs, and flanges extending outwardly from the ends of the legs remote from the base, said outside saddle being dimensioned to accept said inside saddle therewithin with the base and the legs of said outside saddle in close engagement with the base and the legs of said inside saddle and the legs of said outside saddle extending up along the legs of said inside saddle at least past the holes therein said outside saddle being made from a relatively but not totally inflexible material; (c) a top plate; (d) first means for retaining said inside saddle in place within said outside saddle; and (e) second means for retaining said top plate in place on the base of said outside saddle on the side thereof opposite to said inside saddle.
Claim 2
Dependent Claim
