摘要:
A table exchanging device for a wood working machine wherein workpieces of wood can be individually attracted and fixed by a sucking action by vacuum and such sucking action can be maintained also while the slide tables are slidably moved. The device comprises a pair of hollow slide tables having air sucking holes formed in upper walls thereof, a hollow bracket provided in a pneumatically communicating relationship on each slide table, and a hollow tubular shaft provided on each of a pair of left and right beds of the wood working machine and connected to a blower or a vacuum pump. A first hollow arm is supported for horizontal pivotal motion on each hollow bracket and pneumatically communicated with the follow bracket at their mutually connecting location. A second hollow arm is supported for horizontal pivotal motion on each hollow tubular shaft and pneumatically communicated with the hollow tubular shaft at their mutually connection location. Each first hollow arm is connected to the corresponding second hollow arm by means of a shaft and pneumatically communicated with the second hollow arm at their mutually connecting location.

A router fixture for use with a router for trimming an end of a first molding strip to fit a face of another longitudinal molding strip wherein the fixtrue comprises a longitudinal rear guide member for aligning one edge of the first molding strip thereto, a work surface member being fixed to the longitudinal rear guide member at an angle of declination from a given point on said longitudinal rear member for supporting a face of the first molding strip and having a horizontal router support member being mounted above the point on the longitudinal rear guide member and spaced from the face of the work surface member so that the first molding strip may pass beneath the horizontal router support member. The horizontal router support member includes an edge guide transverse to the molding strip so that the cutter of the router is guided across the end of said first molding strip. The router fixture may be equipped with first and second work surface members and first and second horizontal router support members to trim the left or right ends of the molding strips.

摘要:
A woodworking apparatus including a work carriage having a base mounted on a bed for rectilinear sliding movement along a first axis in a first plane and a work platform mounted on the base for rectilinear sliding movement along a second axis parallel to the first axis and in a second plane parallel to the first plane. A tool carriage carrying a motor driven rotary cutting tool is mounted on the bed for rectilinear sliding movement along a third axis transverse to the first and second axes. Levers are provided for actuating movements of the base, the platform, and the tool carriage. A gas spring may be connected with the tool carriage to counterbalance the weight of the tool carriage assembly. A template and following stylus also may be provided for guiding the tool carriage relative to the work carriage in accordance with a predetermined pattern. The work surface supporting a workpiece may be tilted relative to the rotational axis of the cutting tool. Various clamping devices allow adjustment of the tool carriage, the work carriage and their actuators.
摘要:
A machine for machining workpieces, such as panels, planks, and sections. The machine includes a conveyor for conveying workpieces in an infeed direction past a plurality of operating stations fixed in position along a conveying line. A carriage cooperates with the conveyor to support and feed the workpieces. The carriage is coupled with the conveyor for conjoint movement in the feeding direction of the workpieces. The carriage cooperates with other members to form articulated quadrilateral that supports a bar in such manner that the angle formed between the axis of the bar and the conveying line is adjustable. The bar, together with the conveyor, provides support for workpieces being machined.

Machine for fabricating shaped parts, such as chair legs in particular, into which the parts to be shaped are positioned by means of a suitable loader. The parts are moved along a substantially straight path and movable tools are movable at right angles to the course of movement of the parts. The movement of the tools is guided by a suitable means that is indexed to the profile of the finished parts. The tools may be cutters or abrading tools.

Diagonal bracing of a framed wall panel section is provided by a metal brace of U-shaped channel configuration extending diagonally from a top plate of the wall section across a series of studs to the bottom plate of the wall section. Opposed flanges of the brace are fitted into diagonally aligned saw cuts extending into the depth of the top and bottom plates and studs. In a preferred method of making the wall section, an elongated saw guide track is temporarily fastened diagonally across the faces of the studs and the plates. A double-bladed hand saw is run along the length of the saw guide track to form the diagonal saw cuts in the studs and plates. A double-bladed hand saw is run along the length of the saw guide track to form the diagonal saw cuts in the studs and plates. The saw guide is removed, and the flanges of the channel-shaped brace are then fitted into the saw cuts. The brace is then nailed to the plates and the studs.
