A template for use with a jig having a workpiece positioning member. The template supports and guides a cutting tool used to cut joint members in two workpieces and comprises a support surface and at least one set of guides formed on the support surface for guiding the cutting tool. The support surface is movable with respect to the workpiece positioning member a predetermined distance between a first position to cut joint members in one workpiece and a second position to cut complementary joint members in another workpiece. This arrangement permits accurate routing of rounded or square finger joints or other types of uniform, spaced joints as determined by the template being used. Moving the template with respect to fixed workpiece positioning members means that no adjustment of the positioning members or workpieces is necessary between cutting of complementary joint members on separate workpieces which tends to result in more accurate cutting of the joints. In addition, there is disclosed an adjustable guidebush assembly for use with the template to vary the tightness of fit of the joint members.

A special device for producing by machining a multiplicity of shaped bores or shaped external surfaces, such as squares, hexagons, ellipses, polygons. This is done by superimposing a forced radial motion, produced by purely rolling-action elements, on the rotational motion of a tool holder in such a way that the cutting edge of a tool inserted in the tool holder follows the required path as the tool holder rotates. The device enables shaped bores and external surfaces to be produced not only cleanly and to the required tolerances, but also very rapidly and simply. The form drilling and turning device can be used on normal drilling and machining machines and machining centers, as well as on turning machines and power tools.

The sensing head of a measuring machine is pendulously suspended via self-centering ball-and-socket structure which affords resilient dislocating relief from its normal precisely centered position of measurement. The resilient connection permits feeedom for such dislocation for all possible directions in spaces, while effectively anchoring the head against torsional deflection about the vertical axis. Once the collision condition is removed, the self-centering suspension assures resumed precision of the at-rest condition in which measurements can be made.

A follower mechanism for cam-controlled machine tools which is responsive to abrupt changes in the slope of the control cam. A two-link lever system carries a bearing pin and a stylus pin. The bearing pin is engaged to the sensor element of the follower mechanism, and when it is moved sufficiently far laterally in either direction by encountering an abrupt slope, such as a rising or falling shoulder relative to its travel, stops the cam motion and throws the mechanism into a condition which will cause the stylus pin to trace over the surface of the abrupt slope.
