Definitions

  • This invention pertains to the construction of log walls and utilizes natural tapered whole logs which are fit together and laid horizontally on top of each other.
  • this type of wall construction has always been done by hand, using a chainsaw.
  • a lateral notch also known as a groove or cope, is cut with a chainsaw from the underside or belly of each log, and runs the full length of each wall log.
  • This is an extremely heavy, labour intensive and repetitive task.
  • This invention will eliminate the time-consuming hard labour involved, but will still result in the hand-crafted look of tapered log walls.
  • the art and craft of building with natural logs continues to gain appeal, and removing this labour intensive aspect of the construction will allow time for log builders to focus more on innovative and creative hand-crafted corner notches and other details unique to their own style of building.
  • United States Patent No. 4,312,161 to Goldade teaches the shaping of elongate cylindrical structural members for their interfitting in the construction of walls or similar structures. This provides an example of machine profiled timbers that have been cut from whole logs.
  • FIG. 1 is a perspective view of a section of log wall illustrating the natural taper of the logs as they lay, alternating a butt 11 (largest diameter of a log) with a tip 12 (smallest diameter of a log) and achieving level every 2 rounds (a "round” is a single layer of logs around the complete perimeter of a building).
  • FIG.2 is an end view of a log wall illustrating the alternating butts 11 and tips 12 of logs and indicating common curvature 13, matching the milled convex surface of the top of each log to the milled concave surface on the underside of the log above it.
  • FIG.3 is an enlarged end view of a log wall illustrating the use of a common curvature 13 on various diameters of logs resulting in the exact matching of convex to concave surfaces, joining log to log and illustrating the amount of wood removal in the process: from the underside of a log 14 and from the top side of a log 15.
  • This process utilizes a machine to create the lateral notch, also known as a groove or cope, on the underside of a house building log and to mill a matching convex surface on the top of each log, creating walls that maintain the natural taper of each whole log used (refer to FIG.1 ).
  • the convex curvature of the top of each log will be milled to match the concave curvature on the bottom of the log sitting directly above it, using a common curvature 13 for specified diameters.
  • a 16 inch diameter curvature is defined as being equal to any portion of the perimeter of a 16 inch circle.
  • a 10 inch diameter curvature equals any portion of the perimeter of a 10 inch circle; refer to FIG.3 13.
  • the key factor in this process is to use logs of similar taper and mill them to exactly the same degree of taper. This is accomplished by positioning the log that is to be milled so that the top surface is on a horizontal plane. The concave groove is then cut into that surface. The log is then mechanically rotated 180 degrees so the opposite surface of the log is on top. Once again, hydraulic lifters and laser levellers position the log so that the top surface is essentially on a horizontal plane, with the log held in position so that the planing process results in creating the identical degree of taper in every log. A matching convex curvature is then milled on this surface.
  • level wall height is achieved every 2 rounds* (refer to FIG.l); this is contingent upon logs being stacked so that, at each end of the wall being built, a butt 11 (or largest diameter of a log) alternates with a tip 12 (or smallest diameter of a log); refer to FIG.1.
  • a natural tapered house log milling machine would be designed so that the machine head would move down the length of the log, as opposed to the equipment being stationary and the log being turned and moved. This would enable logs of up to 55 feet in length to be milled.

Abstract

Procédé permettant de fabriquer des billes coniques de divers diamètres destinées à la construction d'habitations, utiles dans des constructions à base de bois rond fabriqué manuellement pour des applications résidentielles et commerciales. Le procédé d'usinage comporte les étapes consistant à enlever de la matière afin de former des entailles latérales, ou rainures ( </= copes >/= ), sur la partie inférieure de chaque bille de paroi, tout en maintenant la conicité naturelle de chaque bille entière utilisée ; usiner chaque bille de sorte que sa courbure convexe supérieure corresponde à la courbure concave inférieure de la bille reposant directement sur celle-ci, au moyen d'une courbure moyenne pour des diamètres spécifiés. Le procédé de rabotage des parties supérieure et inférieure de chaque bille permet d'obtenir un même degré de conicité. On utilise du bois rond et la conicité naturelle de chaque bille est toujours maintenue.
