The zenith of human achievements appears to have been reached. Yet every day brings its new surprises. There seems to be no limit to the output of human genius and ingenuity. We have now the aeroplane skimming through the air with bird-like ease and rapidity; the wireless telegraph and wireless telephone; the leviathan steamship “Olympic,” which annihilates distance between Europe and America and a sight of which would make our ancestors gasp in amazement, as well as other modern marvels. And these pages tell about one of the greatest inventions of all time--a discovery of to-day that will add a crowning glory to successful Twentieth Century endeavor. Bangerter’s Perpetulium Time Clock is most concrete, tangible and eloquent evidence that PERPETUAL FORCE--the greatest of all mechanical problems--is solved at last. PERPETUAL FORCE! Bangerter’s latest and highly successful creation sounds like a fairy story realized. The wizardry of true genius is thus marvellously expressed. Volumes have been written by prominent authors and leading scientific men illustrating the wasted efforts and picturing the despair of many inventors in all ages who failed in their persistent efforts to solve the problem of perpetual force--producing motion. Centuries of unwearying studies and activities only met with failure. It was called an impossible task, a phantom, a phantasy, a freak of the imagination that never could be converted to a practical issue. But the failure of those who attempted and failed in the past could not keep back the energy and force of progress. To-day the problem of perpetual force is really solved. It remained for a young Swiss inventor--Mr. Friedrich Bangerter--to successfully accomplish the heretofore impossible. Bangerter’s Perpetual Time Clock is perfect in theory and practice. It is operated by a principle that cannot fail. A glance at the machine will convince the most skeptical. From time to time we read of wonderful inventions that never get beyond the stage where they are talked about. They are impractical and impossible, because their inventors are fakirs, fanatics or dreamers--inventors lacking the character, knowledge and brains to understand whether or not their ideas are of any realizable value. A PRACTICAL INVENTION
