  • Patent number: 5036895
    Abstract: A copying machine has a sliding table slidable on a board. A pattern plate and a work piece are clamped on the sliding table by a clamping device. A cantilever arm is pivotally coupled on the board. A motor is fixed to the body. A casing is pivotally coupled to the arm by a pin. A shaft is rotatably supported on the casing and is driven by the motor via a belt. A roller and a tool are fixed to the shaft. When the tool contacts the work piece, the casing is caused to rotate away from the arm. The roller is caused to move gradually toward the pattern plate by a resilient force of the belt so that the tool can gradually machine the work piece and so that the tool will not be easily damaged.

  • Patent number: 4567927
    Abstract: An apparatus for forming elliptical shapes on a workpiece. The invention involves a support frame which includes a pair of uprights having cantilevered beams from which are suspended a support disk. A pair of mutually perpendicular trammel tracks are set into this support frame. A journaled block is mounted into each trammel track. A trammel beam is rotatably mounted to the two journaled blocks, and a tool attached to the trammel beam, so that as the trammel beam rotates, with the blocks restricted to slide each only in its own track, the tool is required to follow an elliptical path. A ring is caused to revolve about the support frame by a prime mover. Attached to the ring is a bearing block, which slideably holds one end of the trammel beam. Thus as the ring revolves, the beam is caused to automatically and continually rotate, with the tool following its elliptical path.

  • Patent number: 4528780
    Abstract: A process and apparatus for the control of the path of the grinding tool of an all-around edge grinding machine supporting a glass pane for movement about a rotational axis. The grinding tool is positively guided into contact with the edge of the glass pane as controlled by the contour of the glass pane. A scanning roller, also guided into contact with the edge of the glass panel provides the control heretofore described. Both the grinding head and scanning roller are movable in a direction toward the rotational axis of the glass pane. Path signals determined by the scanning roller are stored in a sliding register, and delayed at its output for a period of time required for movement of the glass pane through an angle which corresponds to the rotational angle (.alpha.,.beta.) between the point of contact of the scanning roller and the point of contact of the grinding tool on the edge of the glass pane. The path signals from the sliding register are used in position controlling the grinding tool.

  • Patent number: 4509572
    Abstract: This concerns a machine press for woodworking, particularly to produce mortises and tenons, and characterized by its simple construction, yet allowing rapid and accurate operation. This woodworking press comprises a base, a first carriage slidable to and fro relative to a cutting tool, a second carriage slidable on the first carriage transversely relative to the direction of the first carriage, an actuation arm pivotally connected to the base and to the second carriage to selectively displace either carriage in its corresponding direction, a crank readily accessible to adjust the cutting tool in height with respect to the two carriages, and various abutments and adjustable stops to rapidly position the piece of wood or board, and produce the desired depth and lengths of cuts.

  • Patent number: 4306598
    Abstract: A trammel beam carrying a pair of dove-tail shaped slider blocks rotatably carried on a pair of adjustable trammel points is attached to a workpiece support base which includes a pair of crossed right angle mutually perpendicular dove-tail tracks along which the slider blocks move as the trammel beam or workpiece support base are rotated relative one another. The trammel beam is provided with means permitting it to be mounted to a router or other cutting machine so that if the workpiece support base is attached to the surface of a workpiece, relative movement between the cutting machine and the workpiece will be restricted to an elliptical path as the movement is guided by the trammel.

  • Patent number: 4194543
    Abstract: A grooving indexer is provided for use with routing apparatus to improve the capability of the apparatus for rapidly routing straight parallel grooves in cabinet doors and similar panels. The routing apparatus is of the type in which a router is mounted on the end of a bar for extension over a panel to be routed and in which the router can be moved in any direction across the panel by reason of the bar being mounted on a carrier for longitudinal movement in one dimension of the panel, and the carrier being mounted for movement parallel to the other dimension of the panel. The grooving indexer comprises a series of stops adjustable longitudinally of the bar and a pivotal lever on the carriage biased into engagement with the stops to prevent longitudinal movement of the bar unless the lever is tripped.

  • Patent number: 4185671
    Abstract: An accessory is provided for use with routing apparatus to facilitate the routing of arcuate designs in cabinet doors and similar panels. The routing apparatus is of the type in which a router is mounted on the end of a bar for extension over a panel to be routed and in which the router can be moved in any direction in a plane parallel to the panel by reason of the bar being mounted in a carrier for longitudinal movement in one dimension of the panel, and the carrier being mounted for movement parallel to the other dimension of the panel. The accessory comprises a radius arm which may be adjustably connected at one end to the bar and is slidably mounted in a pivot block mounted for movement in the same direction as the carriage. An adjustable stop on the radius arm limits its longitudinal movement and an adjustable stop limits movement of the pivot block whereby the router can be guided in a preselected curved path by causing the radius arm to pivot around the pivot block.

  • Patent number: 4000766
    Abstract: A lathe duplicator is constructed by mounting a conventional router on one arm of a member mounted to pivot on a guide rail. A second arm of the pivoting member is adapted to guide on a template to control the position of the router bit with respect to a revolving work stock. The router bit is oriented to rotate approximately normal the axis of rotation of the work stock. By rotating the template at the same rate as the work stock, complex surfaces, for example, gun stocks, can be duplicated. The template may be reversed in its direction of rotation to produce reverse surfaces on the work stock. The device is capable of producing spirals and other complex surface configurations.

  • Patent number: 3957095
    Abstract: The rough hewn bench plane attachment of the present invention allows a standard bench plane to be converted into a hewing tool that is able to create hewn lumber similar in shape and design to hand-hewn lumber. The attachment incorporates a chassis assembly mounted under the front knob of the bench plane. An eccentric rolling assembly connects to the chassis assembly and causes an eccentric rolling effect as it rolls over the lumber. This eccentric movement of the wheels causes the bench plane to correspondingly move in an eccentric manner with respect to the workpiece so that a cutting iron of the invention replacing the regular cutting iron of the plane generates varying depth gouges in the lumber workpiece. The cutting iron of the invention has an arcuate cutting edge that enhances the hewing of the lumber by varying the transverse depth of the cutting edge in the lumber workpiece.
