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.
Claims5
A woodworking press comprising a base, superposed lower and upper carriages slidably mounted on said base and on said lower carriage respectively for horizontal guided displacement at right angles one with respect to the other relative to said base, said upper carriage forming a horizontal work supporting surface, a single generally upright actuation arm pivoted to said base at its lower end about a first universal joint and to said top carriage about a second universal joint, said arm also longitudinally slidable relative to said second universal joint, actuation of said arm causing movement of said upper carriage in any horizontal direction, a pair of upright spaced support rods fixedly secured to said base, upwardly projecting therefrom and located exteriorly of the area of displacement of said upper and lower carriages, a top cross bar interconnecting the ends of said support rods, a third plate-like carriage slidably mounted on said support rods for vertical movement therealong, said third carriage having a back surface and a front surface, the latter facing towards said upper and lower carriages, said third carriage having an aperture made therein, a power-driven router removeably secured to said third carriage at the back surface thereof so as to be movable therewith, a horizontally disposed cutting tool operatively carried by said router and extending through said aperture of said third carriage and protruding from said front surface towards the upper and lower carriages, upright screw means extending through and screwed within said cross bar and rotatively attached to said third carriage at its lower end, and manually actuable means at the top end of said screw means exposed above said cross bar to rotate said screw means and adjust the height of said cutting tool relative to said work supporting surface.
