A crowning result of his strenuous labor on this marvelous clock was the outcome of three other inventions which the studies in a large field of problems have brought to life as his anniversary self-winding clock, his fire alarm and sprinkler apparatus. These inventions and others not here mentioned, owing to lack of space, stamp Friedrich Bangerter as a most unusual and fertile-minded inventor. His crowning achievement in inventing that marvel of marvels-- BANGERTER’S PERPETUAL TIME CLOCK has therefore a background of brilliant accomplishments, profound studies and many natural abilities behind a work that shall ever establish his fame as inventor of The Perpetual Clock.

Thousands of Collar Buttons of His Make Were Sold Within the Exposition Grounds.] [Illustration: BANGERTER’S AIRSHIP, THE STAR. Mr. Bangerter conceived the plans of his airship in 1898 and deposited the plans in France in March, 1905. By his principles the basket, engine and traveler being about fifteen feet below the planes, it is an absolute impossibility for it to turn turtle, either by wind or storm. The four planes automatically acting as parachutes in case of descending. This airship can rise vertically and keep steady at any height, permitting the dropping of explosives with accuracy after having aimed and regulated its position.] [Illustration: BANGERTER’S POWDERLESS GUN.
