  • Patent number: 8678177
    Abstract: A combination slider block and pusher lug for mounting on a base plate mounted on a transfer chain includes a flanged channel having a latch and a base plate receiving cavity for snugly fitting over the base plate. A pair of flanges extend inwardly in opposed facing relation over the cavity from the sides of the channel so as to define a slot sized to receive the mount such as the weld between the base plate and the chain. The web of the flanged channel has a lug mounted orthogonally thereto. The cavity has an opening at one end, sized to receive the base plate therethrough. An opposite end of the cavity includes a stop to arrest sliding translation of the base plate through and along the cavity. The latch is mounted adjacent the opening. The latch operates to selectively lock the base plate in the cavity.

  • Patent number: 7530448
    Abstract: A workpiece support mountable onto a workpiece conveyor, the support including a rigid vertically upstanding member, which is vertical when mounted onto an upper-most surface of the workpiece conveyor, and a cap mounted onto the upstanding member. The cap includes a housing defining a cavity. The housing is substantially entirely sealed around the cavity so as to inhibit detritus entering the cavity. The cavity has an opening at a lower-most end thereof. The opening is for snug mounting of the cap onto the upstanding member when the upstanding member is journalled snugly in the cavity.
