Rotary Gaining Cutter Patents (Class 144/203)
  • Publication number: 20150027587
    Abstract: An apparatus used for cutting tenons consists of a plurality of mounting brackets, a plurality of arms, a motor, and a pair of threaded rods. The plurality of mounting brackets attaches the apparatus to an external platform. The motor is mounted onto one of the plurality of arms allowing the motor to slide along the length of the arm. The log in which the tenon is to be cut is placed in between the pair of threaded rods. By rotating the log with the use of one of the threaded rods or with the use of a drill, the log makes contact with the motor. The rotating motion of both the log and also the motor, results in a tenon being cut on the log. Additionally, two motors can also be used in tenon cutting such that a tenon with different diameters can be cut simultaneously.

  • Patent number: 7644742
    Abstract: The woodworking machine for shaping molding has a hollow cylindrical cartridge with end caps having openings defined therein adapted for inserting a blank strip of molding through the cartridge. Robotic grippers advance the molding strip through the cartridge in indexed increments. A cutter assembly is mounted on a movable table, the cutter assembly having a plurality of spaced apart cutters. An electronic control system, preferably including a programmable logic controller, causes the grippers to grip the blank molding, insert the blank through the cartridge, actuate the cutter assembly and move the table so that the cutters simultaneously cut a plurality of notches in the molding, retract the cutter assembly, advance the molding the indexed distance, and automatically repeat the cycle, ejecting the strip when notches have been formed in the entire length of the molding. The machine may be used to form dental molding.

  • Patent number: 6799615
    Abstract: A stand is made up of two channel shaped sides. There is a removable top that has holes drilled in it so a router with router bits of different diameters and shapes, such as round-nosed and straight router bits or heads, can be attached. There is a removable wood guide having a front with two wood guide sides attached to it. The electric router is the power source for the cutter. The round nose bit cuts the wood ends to form tenons of different diameters and shapes, such as radius, chamfered (tapered) or square-shouldered tenons. The top will be a flat surface with holes that will support a router and attach to the sides. The two channel shaped sides will include holes for attaching a top, securing it to a work bench, and attaching wood guides. The fronts will have different diameter holes, and will attach to wood guide sides. The wood guide sides will have a slot where a bolt can pass through to attach wood guides to channel sides.

  • Patent number: 6698476
    Abstract: An apparatus includes a structure supporting a circular blade, a carriage on the structure for linear movement relative to the blade, and a lathe mounted on the carriage, the lathe rotatably supporting a workpiece in proximity to the blade. In one aspect, the support structure is pivotally connected to the carriage to allow pivoting of the lathe between an orientation for engagement of the workpiece with the blade and an orientation in which the workpiece is supported remote from the blade to facilitate operations on the workpiece with a tool implement other than the blade. In another aspect, the support plate is moveable with respect to the carriage in a direction orthogonal to a line parallel with the direction of allowed movement of the carriage relative to the frame, and a pattern plate is mounted to the support plate to control workpiece depth of cut.

  • Patent number: 6595252
    Abstract: A method of producing the floor-bridging units, which increases production rate of the floor-bridging units. First rough lumber beams are fed through a planer, which planes the lumber to the required consistent size tolerance. The planed lumber is transferred to a cut-off saw to cut the legs. The legs are transferred to a dado machine and a dado slot is cut into the lumber. The legs are transferred to a joining station to form the X member, where the dado slots are joined into a dado joint by gluing and stapling the joint. The X member is transferred to a trimming station to be trimmed. At the same time flanges are being made by cutting sheet lumber in strips and then into rectangles to form the flanges. The flanges are transferred to a nailing jig, while glue is applied to the trimmed ends of the legs of the X members. The X members with the applied glue are transferred to the nailing jig.

  • Patent number: 5655583
    Abstract: A tenonizer apparatus has a motor and a circular cutting blade assembly mounted on a pivotable platform. A radius shoulder support shaft is pivotably mounted perpendicular to the circular cutting blade. The operator pushes and rotates the log along the shafts to create the tenon. Only one tenon can be cut at a time. A minimal set up time is required to switch between tenon types. The pivotable platform allows variable length tenons to be cut. The apparatus is portable.

  • Patent number: 5492160
    Abstract: A mortise and tenon generating system 10 having a removable tenon template 12 that attaches to the work piece. A router 26 utilizing a router bit 18 with a bearing collar 30 is guided so that the bearing collar 30 circumferentially contacts a guide edge 54 on the tenon template 12 and machines the tenon 36 out of the work piece 18. A router jig 16 with a tilting table 100 having a machining opening 118 is provided for supporting the router 26 and receiving the router bit 28. The router jig 16 also includes a clamp assembly 98 with a rotatable guide member 168 for receiving the work piece. The tilting table 100 and rotatable guide member 168 allow the work piece to be oriented at a variety of angles with respect to the router bit 28, for the creation of angled and compound angled tenons and/or mortises.

  • Patent number: 4903743
    Abstract: A woodworking machine comprising at least one tenoning-and-mortizing spindle associated with a length-cutting device and a pivoting roller table consisting of a roller carriage and an associated table plate receiving the workpiece and pivoting about said carriage around a vertical axis is designed in such a manner that in spite of the pivotability of the roller table or of its table plate the same length of the oblique window wood will be obtained in any angular position of said roller table or its table plate. For that purpose the invention provides that the vertical pivot axis of the roller table or its table plate be located on the straight line of intersection between two parallel planes of which one is parallel to the direction of advance of the roller table and includes that side of the saw blade of the length-cutting device which faces the workpiece, whereas the other plane includes one of the two longitudinal sides of the workpiece, the two planes subtending an angle >

  • Patent number: 4098310
    Abstract: Apparatus for cutting off and beveling the ends of wood web components for trusses. A length of lumber is guided longitudinally into the machine against a stop and clamped near its lead end, following which the clamped portion is cut off to component length, the stop retracted, and the clamped portion automatically moved laterally to pass its ends across a pair of two-way beveling saws. The beveled clamped portion is then returned to starting position where it is automatically unclamped and then manually pushed longitudinally past the retracted stop to be engaged by an ejection device which discharges the component from the machine and automatically extends the stop into the path of the next component.
