Abstract: This invention is concerned with a folding four wheeled frame for a pushchair which has two front and two rear upwardly extending supports each of which carries at its lower end a wheel. The supports are pivotally connected to an upwardly extending backbone, and also connected near their lower ends to the lower end of the backbone by means of separate pivotal links. The front supports are connected near their upper ends to a first mounting adjacent to the top of the backbone by means of separate pivotal links, and the upper ends of the rear supports are pivotally connected to a second mounting on the backbone adjacent to the first mounting. The arrangement of the supports, backbone and mountings is such that the two mountings can be moved relatively to one another along the backbone whereupon the pivotal links enable the four supports to swing between a closed position nearer to the backbone and an open position further away from the backbone.

Abstract: A lubrication system for periodically lubricating the chain of an endless chain conveyor. A star wheel carrying a lubrication discharge fitting on one arm is mounted for rotation coaxial with a constant radius end turn section of an endless chain conveyor. The ends of the arms of the star wheel are engaged by the chain pins of the conveyor as the pins pass around the end turn section to drive the star wheel in rotation coordinated with movement of the chain. A lubricant supply is connected to the discharge fitting and a control system, when actuated, is operaable to reciprocate the lubricant discharge fitting into seated engagement with a lubricant receiving fitting on a chain pin traversing the end section, to discharge a charge of lubricant from the supply into the pin while the two fittings are engaged, and to retract the discharge fitting clear of the receiving fitting of the pin before the pin leaves the end turn section. A lubricant fitting is mounted on only one of several arms of the star wheel and thus the fitting does not engage adjacent chain pins in succession. The number of arms on the star wheel is related to the number of pins on the chain so that every pin on the chain is lubricated once before any given pin is lubricated twice.
