Abstract: A snap-on wear pad is adapted to be used on conveyor chains. The wear pad includes a resilient, generally cylindrical body portion of a length adapted to fit between the opposite inner side bars of a conveyor chain. The body portion has an axial through hole and an axial entrance slot communicating with the through hole from the outer surface of the body, whereby the body can be snapped onto and resiliently held around the chain roller, bushing, or pin. The wear surface comprises an integral tab portion on the surface of the body opposite the entrance slot, providing an abrasive-resistant sliding surface and means to prevent rotation of the wear pad about the chain roller, bushing, or pin. An alternate construction comprises a composite two-piece wear pad assembly in which identical wear pad halves are similarly snapped onto the chain roller, bushing, or pin from opposite sides to provide a wear surface for both sides of the chain.

Abstract: The barrels of the links of pintle chain for operation open end forward over a drive sprocket are extended inwardly respecting the tooth pockets of the sprocket and two, flat separately distinct areas of interengagement are provided. The two areas of interengagement include the bottom face of the barrel and the bottom face of the tooth pocket and the forward tooth face and rear barrel face. The intermediate corners of the tooth pockets and of the barrel are rounded only for practical purposes.

Abstract: An endless conveyor chain is a sequential assembly of block links formed of a polymeric material, interconnected by thin fleixble links of undulated shape, formed of either metallic or polymeric material, which are easily capable of flexing through their thicknesses, making it possible for the chain to negotiate lateral turns in the conveying run by producing edgewise flexure in the links. Large bearing stresses, which normally result in applications where chain joint lateral articulation occurs in nonlinear chain travel, are minimized or eliminated since the requisite lateral movement is allowed by flexure in the thin links away from the chain joints.

Abstract: A T-headed pin for use in rivetless chain, generally of the trolley conveyor type, is disclosed. The pin can entirely replace the conventional forged pin of any ordinary size and has superior design matching abilities. It is unique in that it is constructed entirely from a flat piece of sheet metal. Rectangular metal blanks with paired oppositely projecting tabs are provided. The blank is first curled to form the body of the pin with the tabs projecting endwise therefrom. In automated manufacture of chain of the type mentioned in selected lengths, the links may be readily assembled with curled pins having tabs projecting axially from both ends. The tabs may then be bent as required to complete the chain length. Alternatively, the tabs at one end only may be bent and lengths of chain may be readily assembled by inserting the other end of each pin into place and then bending the tabs at said other end. In the manufacture of the pins separately of chain assembly, the curled pin with projecting tabs is supported between two members of the exact width required between the T-heads of the finished pin. Opposite curling tools then move toward the tabs and form them in a sequence of steps which prevents or reduces tearing of the metal of the edges of the tabs where they merge into a curled portion forming the pin. Alternatively, the tabs may be bent prior to curling or partially bent prior to curling followed by a complete bending.
