A spring clip is capable of selective installation on and removal from a pair of adjacent pins in a roller chain. The spring clip has a body portion formed of sheet spring metal and an opening at each of its opposite ends. The intermediate section of the body portion is preformed into an arc to establish a predetermined linear distance between the openings. The openings may only be simultaneously received by and installed at recesses at the extended ends of each pin by deforming the arc of the intermediate section to alter the distance between the openings to a magnitude generally corresponding to a predetermined distance between the pins. When both openings are simultaneously installed at the recessed portions of their respective pins, the arc of the intermediate section tends to re-establish the predetermined linear distance to prevent inadvertent removal of the spring clip from the pins.

Roller chain connecting link spring clip

A conveyor chain comprising at least two pivotally connected links, each of said links comprising a flat body portion having a container carrying supporting face, two sets of at least two apertured ears projecting from an integral width of said flat body portion and on opposite sides thereof, said ears being spaced in side by side relation with respect to each other to interfit and align with the apertured ears of an adjoining link on the respective sides thereof, the apertures of said ears on each side of said flat body portion being in alignment, a grooved pin disposed in said aligned apertures of said interfitting ears, at least two of said ears being axially displaced to define an ear gap, said groove on said pin being in alignment with said ear gap, a holding ring means locked on said pin at said groove within said ear gap to hold said grooved pin within said aligned apertures and thereby holding said pivotally connected links in operational position.
