Abstract:
A hand tool useful in forming a pocket mortise in the surface of a workpiece proximate an edge of the workpiece. The hand tool includes a clamping assembly for releasably clamping the tool to the workpiece, and a router carried by the clamp assembly and mounted for manual displacement toward the workpiece edge at an incline to progressively cut deeper into the workpiece and form an inclined pocket mortise. The hand tool also preferably carries a drill bit guide on the clamp assembly which is formed to receive and guide a drill bit from a hand drill for drilling a bore from the workpiece edge to the mortise. A method of forming a pocket mortise including the steps of clamping the clamp assembly with a movable router to a workpiece, routing the pocket mortise and then drilling a hole to the pocket mortise from the edge of the workpiece by a hand drill also is described.
Abstract:
Rows of wood fillets are assembled into panels by step-wise advancing the rows through two stages of wedge-shaped heating and gluing blocks where the edges of the fillets are pre-heated and then coated with a hot melt adhesive before being brought together with a strip of polyethylene foam between the edges of the fillets. The first stage assembles selected groups of the rows and the second stage joins the several groups so that the entire assemblage is accomplished over a relatively short distance and time. The resultant assembly exhibits improved flexibility and cohesiveness.
Abstract:
The process begins with a single board, for instance a flat grain board, of selected dimensions. The single board may be clear or not or may be cut and rejoined to remove defects. The board is then sawn in a selected manner and the resulting boards are bonded together by gluing to form a remanufactured board, in such a manner that the glue lines are substantially invisible. In one preferred embodiment, a flat grain board is rip sawn and then edge glued to form a vertical grain board of selected dimensions.
Abstract:
Described is a procedure for machining wooden articles in which a plurality of machining operations is carried out on a wooden article in a series of machining operation stations.The wooden articles are transported along the series of machining operation stations whereby each article remains fixed on one and the same clamping bench during all operations; following each operation the bench is moved to the next station while the wooden article remains clamped thereon.During moving the clamping is carried out with clamping devices which can move synchronously with the clamping benches; in a station a clamping bench is fixed and the clamping action may be achieved either by stationary clamping devices connected to a station or the clamping devices which can move with a bench.Also is described an installation for carrying out the procedure.
Abstract:
A process for reconfiguring the surfaces of a construction log (10) used in the construction of log structures to produce a log having the appearance of a hand-hewn log. The process includes a first step (30) of chamfering at least the upper and lower forward edge portions (22 and 24) of the log body (12) to produce upper and lower irregularly beveled forward corners (22' and 24'), and a second step (34) of cutting a plurality of indentations (38) into at least the front surface (18) of the log body (12) to produce an irregular front surface. In the third step (48) of the process, the front surface (18) of the log body (12) is scored with a plurality of cuts (54) to mimic the scoring pattern left by hand-wielded hewing tools.
Abstract:
A complete production line assembly of a wooden I-beam manufacturing apparatus is disclosed, wherein generally identical chord members are simultaneously formed by cutting of a wooden stock material into the chord members and simultaneously providing grooves in one surface of each chord into which web members are received to form the I-beam. The individual web members are conveyed as stacks into a web infeed hopper where the individual web members are sequentially discharged from the hopper into a chords and webs assembly line. The web transfer mechanism for conveying the webs to the hopper is fully automated. The individual web members are conveyed along the assembly line between the grooved chords and the chords are converged so that the grooves interfit with the web edges to form the I-beam. The chords and webs assembly line is adjustable by virture of mounting guide rollers on at least one adjustable side frame to enable the line to manufacture wooden I-beams of varying depth. An overhead web drive system is utilized to drive the webs within the assembly line and is vertically adjustable to enable easy access to the assembly line for inspection or repair and to accommodate flange members of different thickness. After the wooden I-beams are cut to desired length, they are conveyed to a stacking area where they are uniquely stacked in a nested and staggered relationship prior to being conveyed for shipping.
Abstract:
A method of manufacturing an elongated braided structural member having high mechanical strength, including the steps of providing at least three primary elongated cores, parallel and spaced from one another, and helically winding a plurality of threads around said cores, at least two threads being wound around any pair of primary cores.
Abstract:
Disclosed herein is a combination log cutter, splitter and bundler for reducing in size logs, preferably to a fireplace length. In addition disclosed herein is a portable device which in one operation saws the wood to an appropriate length, splits the wood, and then bundles it.
Abstract:
Disclosed herein is an automatic apparatus for machining panels or similar articles and, particularly, for drilling and milling them in accordance with the "Folding" system. With this apparatus, the panel to be machined is carried by conveyor means, in a direction parallel to its longitudinal axis, towards drilling and milling devices placed one after the other, the latter being able to mill the panel transversely with respect to the direction in which it moves forward. The operation of the drilling and milling devices takes place contemporaneously in unison, controlled by a feeler device located after the milling devices, which is able to perceive the presence of milling in the panel and to consequently cause the panel to halt and to be in the exact position necessary for the aforementioned drilling and milling devices.
