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.
Claims33
A device for filling holes in wood with a wood filler composition, the device comprising:
- a) a device for filling holes in wood with a wood filler composition comprising a system for moving an attached 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) the product dispensing system comprising a product vessel, wherein the product vessel is designed to contain the wood filler composition and at least two dispensing units, a dispensing unit comprising a rod controller, a rod, and a product tubing, wherein the raising of the rod by the rod controller allows the wood filler composition contained in the vessel to flow into the product tubing;
- and
- c) at least two dispensing nozzles which are housed on the vessel and connected to the product tubing such that the wood filler composition may flow from the product tubing through the dispensing nozzles such that two holes are filled at one time.
A wood filler composition, the composition comprising:
- a) a wood filler composition comprising Gilsonite;
- and
- b) the wood filler composition further comprising sand.
A method for filling rail spike holes simultaneously, the method comprising the steps of:
- a) a method for filling rail spike holes simultaneously comprising mixing Gilsonite and sand to form a wood filler composition;
- and
- b) applying the wood filler composition in at least two rail spike holes at a time, wherein the applying comprises filling at least two wood filler dispensers with the wood filler composition, positioning the wood filler dispensers over the at least two rail spike holes, and releasing the wood filler composition into the at least two rail spike holes.
