Abstract
A composition, device, and method for maintenance of railroad wood ties is presented herein. The device comprises a system for simultaneously filling rail spike holes in wood cross ties including a controlled system able to move in the x, y, and z planes. The system includes a product distribution box with multiple valves and dispensing lines for applying an environmentally friendly wood filler composition into multiple rail spike holes simultaneously. The wood filler composition is applicable for filling holes or gaps in wood to stabilize wood structures.
Claims11
A device for filling at least four holes in wood simultaneously with a dry wood filler mixture, the device comprising:
- a) a hydraulic system for moving an attached gravity fed product dispensing system in an x, y, and z direction, wherein the x, y, and z directions are orthogonal with respect to one another;
- b) a dry product hopper;
- and the gravity fed product dispensing system comprising a tube connecting the dry product hopper to a product vessel, at least four hydraulically powered dispensing units contained inside the product vessel, each of the at least four dispensing units comprising a rod controller, a rod, and a product tubing, wherein a raising of the rod by the rod controller allows the dry wood filler mixture contained in the product vessel to flow into the product tubing;
- and
- c) at least four dispensing nozzles which are housed on the bottom of the product vessel and connected to the product tubing such that the dry wood filler mixture flows via gravity into the product tubing and through the at least four dispensing nozzles such that the at least four holes are filled at one time.
