Huge Typewriter Really Works
SO HUGE that its keys must be operated with the feet, a mammoth typewriter has been placed on exhibition at Atlantic City, N. J. One of its giant type bars is seen about to strike, above, as a champion typist dictates a challenge to rivals.
Ten-Foot FIDDLES and Two-Story HARPS
HOBBYIST BUILDS FREAK INSTRUMENTS FOR WORLD’S ODDEST ORCHESTRA
By EDWIN TEALE
FIDDLES with three necks instead of one; a harp so large you can play it from a second-story window ; a fourteen-foot bass viol, the biggest in the world; combined harps and fiddles which require two musicians to operateâ€”such are the musical curiosities that Arthur K. Ferris, a landscape gardener of Flanders, N. J., has produced in his spare time. Eventually, he hopes to assemble a vast oddity orchestra comprising 126 unusual instruments.
Giant Wind Turbines
Currents in Upper Air Form Unfailing Source of Power for “Windmills” of Future
WIND, at the surface of the earth, is proverbially uncertain; but recent researches show that, a thousand feet or more above the ground, wind is comparatively steady and unfailing. This has given new life to the hope of finding a substantial source of natural power, even more universally available than water power; and the designs illustrated here have been prepared by a German engineer, Honnef, the erector of several huge radio towers. As shown here, the structure carrying the power plant would be higher than any other building man has yet been able to erect.
Huge Barrel Plane for Ocean Flights
PIERCED by a battery of tunnels a flying wing airplane is proposed by an engineer at the famous Caproni airplane works in Italy. Streamlined motors and four-bladed propellers will drive air blasts through the tunnels, each of which forms a Venturi tube, expanding toward the rear. Thus, according to the inventor, the air will give a forward push something in the manner of rocket propulsion. Aided by the Italian government, the designer recently completed a single-engined experimental craft incorporating his ideas. This odd flying barrel was put through successful tests near Rome. (P.S.M., Jan. ’33, p. 18.) Details of the huge machine he proposes to build for transatlantic travel are shown in the pictures above.
LARGEST LOUDSPEAKER HORN FOR AUDITORIUM
Designed for use in auditoriums, the biggest loudspeaker horn yet made has recently appeared on the market. Its twelve-foot opening gives it the appearance of the entrance to a tunnel into which an automobile could be driven. The claim is made for it that it will reen-force notes down to twenty-five vibrations a second and project it with no appreciable loss of tone quality, to the farthest corners of a large concert hall.
Monster Clock Has No Hands
Moving numerals, three feet high, will tell Londoners the time when a monster clock now under construction in one of this British city’s railroad stations is completed. The big timepiece is believed the largest without hands ever built. Three endless belts of steel slats, driven by an electric motor, carry the numbers past a rectangular window high on the station wall where they are made visible. Each numeral is outlined by silvered disks of reflecting material, and floodlights play upon the figures to make them show up clearly at a distance. The movement of the belts is governed automatically from a control panel with an extremely accurate master clock, which in turn is constantly regulated from the observatory at Greenwich. The steel roller on which the hour numerals are shown is thirty-seven feet long and the blinds weigh about 15,000 pounds.
Huge Truck FOR LAND OR WATER CARRIES SHIPLOAD OF CARGO
IMAGINE a motor truck so large that it dwarfs the biggest locomotive in the world â€”a veritable ship of the land, rolling on pneumatic tires as high as a bungalow. Fit this juggernaut, in your mind’s eye, with a boat-like hull, a Diesel motor, and an electric drive; add a propeller and rudder so that it can navigate in the water as well as on dry ground; fill its capacious hold with hundreds of tons of cargo, and send it roaring across the continent or through a wilderness to its destination. Then you will have a mental image of the 1,500-ton, amphibian super-truck that Eric R. Lyon, associate professor of physics at the Kansas State Agricultural College, predicts will be the freight-carrying vehicle of the future. To prove it feasible, he himself has worked out the engineering design of such a machine, which he calls the “navitruck,” and which our artist illustrates here and on the cover of this issue.
Giant Television Images
By H. WINFIELD SECOR
ULYSSES A. SANABRIA is one of the foremost geniuses in Television today. Mr. Sanabria is only 24 years of age, yet this youthful electrical wizard has demonstrated to the engineering fraternity and to the press, the largest television images thus far shown. The author was present at the New York demonstration when television images six and one-half feet square were exhibited and they were surprisingly clear. At the New York Radio Show, television images 10 by 14 ft., have been promised by Sanabria. The following description of the Sanabria system for producing these gigantic television images is authentic and was obtained in a recent interview with Mr. Sanabria.
AT the Radio Trade Show held in Chicago last spring, and also at a recent demonstration given to engineers and members of the press in New York City, Ulysses A. Sanabria startled his audience by showing surprisingly clear television images six and one-half feet square. Many of those present took advantage of the inventor’s invitation to stand in front of the television pickup, and thus have the images of their faces projected on the glass exhibition screen, much to the enjoyment of their friends. Considerable merriment was caused when some of the wittier ones, who posed in front of the photo-cells, made a few remarks which were picked up by a microphone and sent through an amplifier to a loud speaker below the glass screen on which the moving images of the speaker appeared.
Six Persons Play Giant Accordion at Once
Six persons can play simultaneously on a gigantic accordion recently exhibited in Germany. Over six feet high, the mammoth musical instrument has a keyboard covering more than ten octaves. Casters at the base facilitate the manipulation of the bellows.
Giant Coffee Urn In Service
THE U. S. Coast Guard base at New London, Connecticut, has been provided with a coffee urn which is believed to be the largest ever constructed. It holds 60 gallons of water and the handle on its cover is just within reach of an average size girl. The big coffee maker is the center of attraction on cold nights for men returning from chilly excursions aboard patrol boats.
