Patent number: 5301934Abstract: A twin screw vise utilizing two threaded vise screw rods that are journaled through flanged nuts fixed to a workbench top or to a rear, fixed bench jaw. The vise screws pass through a movable front jaw and into tee-castings and handles that may be turned to rotate the screws. Sprockets are located on each screw between the tee castings and the front jaw and are coupled by a chain. One of the sprockets is fixed in position on its screw during a calibration procedure. The other sprocket remains free to rotate on its screw, except when a spring loaded pin in the corresponding tee-casting engages a depression in the face of the sprocket, thereby coupling that sprocket to the tee casting and associated screw.Type: GrantFiled: August 10, 1992Date of Patent: April 12, 1994Assignee: Lee Valley Tools Ltd.Inventors: John S.

Patent number: 5284331Abstract: A woodworking bench and related fixtures providing an integrated system of bench features, vises, dogs, panel clamps, hold-downs and fixtures that cooperate to provide a highly flexible workpiece holding and clamping apparatus able to accommodate a wide variety of shapes and sizes of workpieces and hold such workpieces in an enormous variety of positions during numerous different operations. Two substantial slabs provide the bench top surface and carry a rectilinear pattern (in rows and files) of round, vertical bench dog holes. The rectilinear pattern of round bench dog holes with specific, equal spacing between holes, and similar holes in the edge of the top, facilitate great flexibility in clamping using conventional round dogs in the bench top holes and corresponding dogs in bench edge-mounted, or end-mounted vises. Such holes also accommodate other clamping, fixing and hold-down fixtures that contribute to flexibility and utility.Type: GrantFiled: October 15, 1992Date of Patent: February 8, 1994Assignee: Lee Valley Tools Ltd.Inventors: Leonard G.
