A conveyor lubricator for lubricating moving parts in a conveyor mechanism comprises an air operated oil injector that dispenses a measured quantity of oil on each part to be lubricated when such part reaches a predetermined position on the track; an air assist mechanism that generates an air flow across the oil outlet so as to urge the oil toward said predetermined position; and a cam operated actuator valve that provides air pressure to actuate the oil injector and air assist whenever a moving part reaches said predetermined position. A timed pulse valve connected to the actuator valve automatically deactivates the air flow after a predetermined period of time, even if the actuator valve still remains actuated by continued engagement with the conveyor. More than one cam operated actuator valve can be employed in the system in order to provide lubrication for an increased number of moving parts of the conveyor mechanism with a single set of oil injectors. The cam operated actuator valve includes an adjustment mechanism that permits placement of the valve in different positions. The lubricator also can include a selective actuation mechanism in order to actuate and deactuate the system whenever desired. An air counter can be employed to automatically actuate and deactuate the system at regular intervals.

Conveyor lubricating means for lubricating moving parts of a conveyor mechanism wherein a series of interconnected wheeled trolleys ride along a track, said lubricating means comprising: oil supply means for supplying liquid lubricant to the lubricating means; actuator valve means for controlling the flow of pressurized air to the lubricating means, said actuator valve means having inlet means for receiving air from an air supply means and outlet means for delivering air from the actuator means to the lubricating means, said actuator valve means having an open position wherein air is permitted to flow to the lubricating means and a closed position wherein the flow of air to the lubricating means is blocked; oil dispensing valve means having air inlet means for receiving pressurized air from the outlet means of the actuator valve means, oil inlet means for receiving liquid lubricant from the outlet of the oil supply means, and oil outlet means for delivering liquid lubricant from the oil dispensing valve means, said oil dispensing valve means being actuated by the receipt of pressurized air through the air inlet means and being adapted to discharge a predetermined quantity of liquid lubricant from the oil outlet means each time the oil dispensing valve is actuated, said oil dispensing means being actuated only once each time the actuator valve means is opened and delivering the same predetermined quantity of liquid lubricant from the oil outlet means regardless of the amount of time the actuator valve remains open before closing, said oil dispensing valve means comprising a hollow housing including an oil chamber of predetermined volume and an air driven plunger slidably mounted in the housing for reciprocation into and out of the oil chamber, the plunger having a predetermined stroke into the oil chamber, the oil inlet and outlet means being formed in the oil chamber, with the oil outlet means including means to prevent liquid lubricant from being drawn back into the oil chamber when the plunger is withdrawn from the oil chamber, said air inlet means being formed in an air chamber adjacent the end of the plunger facing away from the oil chamber such that the introduction of pressurized air into the air inlet means drives the piston into the oil chamber and causes the ejection of a predetermined quantity of liquid lubricant from the oil outlet means, said oil dispensing valve means including resilient biasing means for urging the plunger out of the oil chamber when the air pressure in the air chamber is relieved; oil conduit means having a conduit inlet connected to the oil dispensing valve oil outlet means and a conduit outlet positioned adjacent a predetermined position on the track, said oil conduit means being adapted to convey liquid lubricant from the oil dispensing valve oil outlet means to said predetermined position when the oil dispensing valve means is actuated; air assist means for urging mechanically dispensed liquid lubricant from the oil conduit outlet to said predetermined position, said air assist means including air conduit means having an inlet in communication with the outlet means of the actuator valve means and an outlet adjacent said predetermined position and adjacent but not in said oil conduit outlet, said air assist means being adapted to convey pressurized air from the air conduit outlet means over the outside of the oil conduit outlet to said predetermined position when the actuator valve means is open; nozzle means connected to the outlets of the air and oil conduit means, said nozzle means being formed such that liquid lubricant dispensed from the outlet of the oil conduit is entrained in the air leaving the outlet of the air conduit and urged from the nozzle means to said predetermined position; and actuating means for temporarily opening the actuator valve means each time a part to be lubricated reaches said predetermined position on the track such that liquid lubricant discharged from the nozzle means is deposited on the part.
