Description:

Toulmin & Toulmin - patent attorneys

Our invention relates to lathes and in particular to universal lathes wherein the motion of the cutting tool relative to the work is automatically guided. An object of our invention is to provide a lathe wherein the cutting tool is automatically guided relative to the work, which it is cutting. Another object is to provide a lathe carriage with guiding mechanism whereby the longitudinal and cross-power feeds are operated automatically by a guiding member. Another object is to provide such a lathe carriage having a guiding member, differential gearing interconnecting the longitudinal and crosspower feeds and a follower engaging the guiding member, thereby setting up resistance which operates the differential gearing, so that the longitudinal and cross-power feeds will be actuated in such varying proportions as to cause the cam followed and cutting tool to follow paths like or similar to the contour of the guiding member. Another object is to provide a lathe carriage with the above-described automatic guiding mechanism by mechanical means only, as distinguished from electrical means. Another object is to provide braking mechanisms interconnected with the longitudinal feed and also with the cross feed to permit the use of a single-sided guiding member. Another object is to provide such mechanism as above described wherein the path of travel of the cutting tool of a lathe is controlled in such a manner from a guiding member as to create any predetermined shape or combination of shapes.
