Abstract: A self-unloading bed includes a conveyor with chain bars that are strong, light-weight and non-damaging to the floor upon which the conveyor slides. The preferred chain bar is an elongated bar with two legs, each of said two legs having a foot. The feet extend away from the leading (unloading) direction, the transition from leg to foot being formed by smooth bends, so that no sharp edges exist that would gouge into the floor as the chain bar moves across the floor. The preferred chain bar, made of a single metal bar with four longitudinal bends, is extremely strong for its weight, and it unlikely to bend or gouge into the floor during use.

Abstract: A belt conveyor having clutch-driven flights for extremely low-torque operation. The flights have pivot members that rotate about an axis over a limited range of angles.

Abstract: A high speed sheet feeder machine includes at least one pusher that follows a loop-shaped path of travel as the machine operates. The pusher pushes an insert into an envelope during a forward and downward part of its path of travel and then retreats rearwardly and upwardly along the loop-shaped path of travel before repeating an insertion. In this way, the pusher makes no abrupt changes in its path of travel. Very high rates of insertion are made possible by providing multiple pushers at longitudinally spaced apart intervals along the loop-shaped path of travel. A stop plate is integrally formed with each pusher assembly and a fixed position barrier is mounted on the machine adjacent the rearward end of the loop-shaped path of travel to prevent over-rotation of each pusher member at very high speeds.

Abstract: A retractable pusher dog for an overhead power and free conveyor system is provided. The retractable pusher dog comprises a body portion formed from a rectangular cylinder with a spring and pusher member disposed within the cylinder. When a force greater than the static spring force is applied to the pusher member, the pusher member retracts into the body portion thus reducing the overall height of the pusher dog. Due to its self-actuating retraction, the retractable pusher dog of the subject invention requires no modifications to the powered and free rails or to the load trolleys. The retractable pusher dog will prevent jamming of load trolleys by allowing the pusher dog to bypass an off-timed load carrier, introduced from a different powered rail, until it is properly aligned on the main rail. Also, the body plates of the pusher dog facilitates coupling the pusher dog to the drive chain without disassembling the drive chain thus reducing downtime of the conveyor system and labor costs.
