This is the most marvelous little machine that science has ever devised to watch your house day and night. It is the truest of all Watch Dogs and will in case of fire make such a loud and noisy alarm that you will wake up from the deepest of sleeps. It calls when the fire is at its infancy, in time to save you and your beloved ones. It is a most simple little apparatus requiring no electricity, no wiring or connections, no care of any kind; just as reliable after it has been hanging in your room for twenty years as it was when newly installed.] [Illustration: BANGERTER’S FIRE ALARM AND SPRINKLER. More than a hundred million dollars is the yearly loss by fire in the United States; 50 per cent. of this loss is by water. How important therefore is Bangerter’s “Watch Dog Fire Alarm and Sprinkler,” regulated to ring, first a loud call when a fire is in its infancy. A watchman or anyone hearing the call can rush to the place and extinguish the fire. The sprinkler will only work when the alarm call is not attended to. Our Fire Alarm and Sprinkler system can be connected to piping from the water main, or to the tank on the roof of a building, but can also be installed in any place if there should be no water piping or tank. In this case a water tank of from twenty to one hundred gallons of water has to be installed. This tank can be set in any out of the way place. Compressed air keeps this water under high pressure, and in case of fire the valves are automatically opened and the sprinkler will act with efficacious result.] BRIEF BIOGRAPHY OF FRIEDRICH BANGERTER Friedrich Bangerter can justly lay claim to being one of this country’s leading inventors. He has some fifty inventions to his credit. He has been honored with Silver and Gold Medals and Diplomas. His displays at great World’s Expositions have occasioned the utmost favorable comment. His splendid record speaks for itself and shows the profound student, the practical machinist and brainy inventor of worldwide experience with a long list of successes to his credit. Born in Lyss, Switzerland, in 1868, at the age of 16 he entered the machine shop of his town’s watch factory as an apprentice. There he was favored with the opportunity to become familiar with all sorts of tools and machines used in making watches. By the age of 22 he so progressed that “all by himself” he constructed all the necessary machines to make watches and added so many important improvements, embracing such automatic devices and machines in which hands, moving from place to place, picking up pieces of work, then setting them in the right positions (operating with such perfection and precision) that he was called a wizard. One of these automatic machines would pick up blanks from a wire, set them in the machine from one to twenty-four at a time and cut the teeth of watch gearing perfectly.
