Counter-bore fins on the fastener head also form a counter-bore for the head. A lubricious coating applied to a portion of the shank accommodates settling of the logs and facilitates installation.

Abstract: Door frames, window frames, baseboards etc are trimmed with solid weed, e.g. oak, trim pieces. The trim pieces are fitted over splines which are screwed to the wall. A jig enables the splines to be located accurately in position. The spline includes no beads, snaps, or other features that would require the oak trim section to flex; instead, the trim is secured by the friction arising from the fit of the spline into a groove cut into the rear face of the trim section. In a variation, a pair of parallel grooves are provided, together with a corresponding pair of splines, which are mounted on a web.

Abstract: A Dual Automated Clamp Carrier provides an apparatus which enables three different activities to be conducted simultaneously at three different levels of the apparatus. The upper level is the location at which clamps previously tightened for gluing panels of wood are untightened automatically. The mid level is the location where the completed panels are removed from the clamps from the loosened clamps and panel segments coated with moist glue are positioned in the clamp for clamping and processing. The lower level is the location where the clamps are automatically tightened. Appropriate support elements for the upper and lower levels allow a carriage including a powered clamp tightener/loosener wrench to be automatically positioned to engage each of the clamps to loosen or tighten the clamps as necessary. The lower carriage also includes an apparatus to flatten the panel segments in each clamp as the clamps are tightened.

Abstract: A furniture frame part or the like is made from a first, planar laminate of wood or other material. This laminate is bent so as to form a shaped member of single curvature. The shaped member is cut into slices in a direction transverse to the generatrices of the curvature, and from these slices a second laminate is made. This second laminate is bent in a direction so as to form another curvature with generatrices extending generally transversely to the first mentioned generatrices, whereby a furniture frame part or another composite body of double curvature may be made.

Abstract: An on-site fabrication method has been devised for compound bending of laminated wooden beam members into a handrail for curved or spiral stairways in which upstanding supports are positioned at intervals along the path of intended curvature on the stairway, the strips are assembled together in juxtaposed relation to one another and retained by leveling brackets on the support members whereby to prevent twisting of the beam members when a lateral force is applied, clamping the beam members together against each support member and permitting the beam members to be cured into a unitary rail section.

Abstract: A structure on which stringers for a free-standing circular staircase are formed in accordance with a time-saving method is disclosed. The structure comprises upper and lower metal patterns connected by vertical beams. The patterns have a plurality of rays attached to a central hub. The beams are attached to equidistant rays at a given distance from the center of the respective pattern. Clamps are affixed at successively higher positions along the perimeter of the circle formed by the beams that hold the stringer while it is being laminated with epoxy resin, until it has become rigid.Separate sets of beams may be used to form inner and outer stringers for a staircase, or the outer stringer may be formed on the same set of beams after the inner stringer has become rigid.

Abstract: A veneer sheet having lathe checks is pressed in at least one of two opposite directions in the same plane as the veneer sheet itself and substantially perpendicular to the directions of its fibers, while another sheet is being bonded to at least one of its two oposite sides, namely, its tight side having no lathe checks and its loose side having the lathe checks. Before the veneer sheet is pressed in this manner, glue may or may not be filled into the lathe checks thereof. Or glue is filled into the lathe checks of the veneer sheet, and is merely hardened, without bonding no other sheet thereto, while the sheet is being pressed in at least one of the foregoing two opposite directions.

The plates or strips (10) may extend over 40%-70% of the length of the beam (15) in the area of maximum deflection of the beam under the applied load to increase the stiffness of the beam by 50%-80%.

Abstract: Glued laminated wood which has a novel laminated structure and may be fabricated from small-sized veneer sheets, and method of manufacturing such laminated wood are provided. The glued laminated wood in its continuous form is made from a series of unit-length veneer sheets each having the same length and thickness which are laminated in a laid-up arrangement in which each of the veneer sheets is lapped on another and offset therefrom in the direction of its length at a regular interval determined by the number of plies to be in the laminated wood product and the length of the unit veneer sheets. It has a novel structure in that each veneer sheet therein has tandemly spaced straight length portions which are parallel to each other, but successively displaced from each other in the direction of the thickness of the product, there being a somewhat S-shaped curved length portion of the veneer sheet between any successive pair of these straight length portions.

Abstract: A plywood is manufactured by applying an aqueous plywood adhesive fluid to the peripheral surface of a heating roll rotating at a given speed by means of a roll coater to form an adhesive fluid film, drying the adhesive fluid film into a tacky-dry film while it is carried on the surface of the heating roll, stripping the tacky-dry adhesive film from the roll surface by pulling it under tension with or without the aid of a stripping knife, interposing the adhesive film between a pair of veneers, and pressing the veneers to each other to bond them.

Abstract: In the process for the production of a glued joint for wood, the surfaces to be glued are held tightly together. At least one injection needle is driven into the wood up to a depth at which the outlet of the needle point comes into contact with the surface. The fluid adhesive is then driven under pressure through the injection needle and evenly distributed between the surfaces. The process is particularly suited for the production of window blind frames made of wood, in which the wood edges to be glued are joined by means of pins and slots. The process makes possible the production of joints of great strength, with very low tolerances between the pins and slots.

Abstract: A method and apparatus for joining veneer strips with an adhesive string between the abutting edges of the veneer strips, which string forms loops between the edges of one side of the veneer, the string being pressed and cemented against the other side of the veneer. The loop is being made by lifting the adhesive string through the plane of movement of the veneer strips using a supply eye in front of a holding hook. Thereafter, the string is being hung into the holding hook by a swinging movement and a following return movement of the supply eye.
