TODAY’S PATENT – GAUGE
In today’s patent, we will discuss Rudolf Och (Nuremberg)’s invention, “GAUGE” (US4517743A), which was patented by the USPTO on May 21, 1985.
The following invention is invented for checking the quality (accuracy; tolerance) of gear teeth that is provided with a set of gauging teeth which, when the gauge is used, mesh with the teeth to be checked. This effects automatic alignment of the actual contact pins relative to the teeth to be checked.One of the major object of the invention is to provide an improved gauge for inspecting and indicating the quality of gear teeth on a piece.It is also highly advantageous that the test operation is fully reproducible, in the sense that the gauging teeth always assure that the testing component(s) will be uniformly located with reference to any desired number of work pieces to be successively checked. This means that even very tight tolerance variations can be checked on a series of successively tested work pieces.Another object of the invention is to provide such an improved gauge in which the insertion of the contact-making test components into the teeth of a piece being checked, is simple and uncomplicated.
