Abstract
The powdered graphite applicator includes a container with a lid at the upper end and a screen at the lower end. A plate is provided inside the container to define the bottom of the graphite chamber. The plate has an enlarged opening which is normally closed by a gate. The gate can be periodically opened to allow graphite to pass through the plate opening, and then to fall from the plate through the screen and onto the surface of an adjacent roller of a rotatable drum. Movement of the gate is controlled by a cylinder with an extensible arm. Extension and retraction of the cylinder arm is automatically controlled by a solenoid and a programmed controller.
Claims12
A powdered graphite applicator for lubricating support rollers of a rotating drum, comprising:
- a container for holding powdered graphite and having open upper and lower ends;
- a lid for covering the upper end of the container and being hinged to the container adjacent the drum so as to open away from the drum;
- a screen at the lower end of the container;
- a plate in the container upstream from the screen and having at least one hole therein through which graphite flows;
- a pivotal gate in the container pivotal between a closed position closing the hole in the plate and an open position opening the hole in the plate;
- whereby graphite passes through the hole in the plate and then through the screen for application to the rollers when the gate is moved towards the open position.
