Description
- This application is a divisional application of pending application 11/018,517, file Dec. 20, 2004 which claims the benefit of provisional application 60/531,033 filed Dec. 18, 2003, the disclosures of which are hereby incorporated by reference herein.
- 1. Field of the Invention
- This invention relates to a method and apparatus for spraying lumber such as trusses with a mold and insect preventative solution.
- 2. Description of the Background Art
- Presently, various pesticides, insecticides and mold preventative solutions exist for spraying lumber and other products. Prior art methods for treating lumber include dipping, pressure-treating, and vacuum treating. Unfortunately, however, treating lumber in bulk results in considerable waste of the treating solutions.
- More particularly, treating an un-manufactured products such as a bundle of lumber results in a significant loss of treated lumber when the treated lumber is subsequently used. Specifically, during the building of a structure, lumber is cut to the designed lengths. The scrap lumber is then simply discarded. The amount of treating solution that was consumed during the treating process for the scrap lumber is therefore wasted. Moreover, scrap wood that has been treated by prior art solutions are sometimes unusable for a recycling plant or other scrap-wood company.
- One current method of externally applying treating solution utilizes a conventional hand pump sprayer. However, due to considerable overspray, hand spraying is wasteful of treating solution.
- Therefore, it is an object of this invention to provide an improvement which overcomes the aforementioned inadequacies of the prior art devices and provides an improvement which is a significant contribution to the advancement of the mold and insect preventative art.
- Another object of this invention is to provide an apparatus and method for applying treating solution to lumber that has been already cut and assembled into a manufactured product such as a truss.
- Another object of this invention is to provide an apparatus and method for applying treating solution to lumber that has been already cut and assembled into a manufactured product such as a truss such that scrap lumber therefrom may be recycled thereby eliminating treating solution waste.
- The foregoing has outlined some of the pertinent objects of the invention. These objects should be construed to be merely illustrative of some of the more prominent features and applications of the intended invention. Many other beneficial results can be attained by applying the disclosed invention in a different manner or modifying the invention within the scope of the disclosure. Accordingly, other objects and a fuller understanding of the invention may be had by referring to the summary of the invention and the detailed description of the preferred embodiment in addition to the scope of the invention defined by the claims taken in conjunction with the accompanying drawings.
- SUMMARY OF THE INVENTION
- The invention is defined by the appended claims with a specific embodiment shown in the attached drawings. For the purpose of summarizing this invention, this invention comprises an apparatus and method for applying a liquid treating solution onto all surfaces of a manufactured truss to prevent mold growth thereon, decay of wood by insects or other degradation of the wood as determined by the treating characteristics of the treating solution.
- Importantly, all of the treating solution that does not penetrate into the wood of the truss as it passes through the apparatus is collected in a tank below the spraying applicators. The treating solution is then continuously circulated from the tank to the spraying applicators.
- The recirculation process of the invention has two major advantages over spraying by hand with a hand pump sprayer. The most significant advantage over an individual hand pump sprayer is that the treating solution is continuously recirculated and none of it is lost to overspray. The second advantage is the time saved spraying the entire truss in one sweep instead of spraying each separate board by hand.
- The spraying apparatus and method of the invention also has an advantage over the other forms of treating methods. Dipping, pressure, and vacuum treatments are all too costly and time consuming. These treatments commonly require that the whole board be treated. Then, when the board to cut to size for a manufactured truss design, a lot of scrap wood is leftover. The treating solution previously used to treat the scrap wood is lost, resulting in unnecessary costs. Furthermore, the treating solution may cause the scrap wood to become unusable or unrecyclable. Finally, some treating solutions require an incubation time after being treated, which could cause further delays before the treated lumber could be used in the manufacturing of a truss.
- The apparatus and method of the present invention is most advantageously used for coating roof and floor trusses with a treating solution which will prevent mold growth and decay from wood destroying organisms. As noted above, according to the subject invention, a manufactured truss, preferably immediately after it is rolled through a press, it passes through the spraying apparatus wherein the treating solution is be sprayed onto every surface of the truss to penetrate the wood itself. This method of applying a treating solution to trusses is designed to eliminate waste, save time, and save money.
- The foregoing has outlined rather broadly the more pertinent and important features of the present invention in order that the detailed description of the invention that follows may be better understood so that the present contribution to the art can be more fully appreciated. Additional features of the invention will be described hereinafter which form the subject of the claims of the invention. It should be appreciated by those skilled in the art that the conception and the specific embodiment disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present invention. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the invention as set forth in the appended claims.
