[[?]] a valuable trophy for competition for heavier-than-air flying machines. The trophy is to be given under a deed of gift to the Aero Club of America, to be competed for annually by both American and foreign inventors. The rules for the competition will be drawn u by a committee of the Aero Club, and it expected that the first competition will occur at the Jamestown Exposition, September 14, and will be for a flight of one mile or less in a straight line. The competition is to be progressive in character, that is to say, if the flight of the predetermined distance is accomplished this year, next year a longer flight will be required, or a flight of a mile with turns. Pioneer Press St. Paul 24 Apr 1907 GO 60 MILES IN BALLOON. -- Philadelphian and New Yorker Make Perilous Descent. Mattawan, N. J., April 23.-A balloon which left Philadelphia at 12:45 o'clock this afternoon landed here at 2:15, having covered the sixty miles in an hour and a half. In the balloon were A. R. Hawley, a New Yorker broker, and Arthur T. Atherhold of Philadelphia. It was Mr. Hawley's seventh balloon trip, while Mr. Atherholt had made three previous aerial voyages. The balloon reached an altitude of 12,000 feet. The sight of open water and a fear that the strong wind might carry the balloon out to sea caused the determination to land. The balloon landed in a creek and both occupants were rather severely shaken up when the basket struck, but were not seriously injured. Eagle Brooklyn. 25-Apr-1907 Rules for Airships at Jamestown Fair -- Special Regulations Made For Flying Machines of Heavier-Than-Air Type. -- Use of gas prohibited. -- Competition, Open for All Other Styles, Will He Held on September 14, at Exposition -- A special committee of the Aero Club of America, appointed for the purpose, has formulated provisional rules governing the competition for flying machines of the heavier-than-air type, which will be inaugurated at the Jamestown Exposition on September 14 next. It is the intention of the Scientific American, in offering this trophy, to have it always open to competition by inventors the world over. Should the trophy be won by the representative of a foreign aeronautical club, this club, if a member of the Federation Aeronautique Internationale, may become the custodian of the trophy; but the future competitions, even if held abroad, shall be carried out under the same rules and conditions used by the Aero Club of America in the competitions held here. The rules governing the competition are as follows: 1. This competition will be held annually, and the conditions of the trials will be progressive in character, so as to keep abreast of the state of the art. The first contest will be held at the Jamestown Exposition on September 14, 1907, and all entries for this contest must be made in writing and sent to the secretary of the Aero Club of America. 12 East Forty-second street, New York City, prior to September 1, 1907. The tules governing future contests will be formulated by the contest committee of the Aero Club of America in accordance with the results obtained and the lessons learned in this first contest. 2. All heavier-than-air machines of any type whatever (aeroplanes, helicopters, orthopters, etc.) shall be entitled to compete for the trophy, but all machines carrying a balloon or gas-containing envelope for purposes of support are excluded from the competition. While these balloon trips are of absorbing fascination, the real secret of flight is being reached by men, who are experimenting with vehicles heavier than air. It is more than a hundred years since the first balloon was launched. These big bags have been made more buoyant as the years went on, but many experimenters contend that the real science of aeronautics has been retarded by the diverting attention to ballooning. The airship of the future must be able to go against the wind. Germany and France have both established schools where the principles and possibilities of flight are taught. There has been much merriment over the whole subject of aerial navigation, but similar levity has been provoked by the pioneer experiments in other fields. When the friends of Morse succeeded in getting a paltry appropriation of thirty thousand dollars to build a telegraph line from Washington to Baltimore, one of the Congressmen who looked upon the possibilities of telegraphy just as cynics now regard airships moved as an amendment that part of the money be used for the survey of a railway route to the moon. The two balloonists who voyaged from Philadelphia and alighted in a Jersey creek will probably agree that better terminal facilities must be provided before balloons can become popular for passenger traffic.

Roy Knabenshue has at last succeeded in his efforts to build the most wonderful gas engine ever constructed. It is the engine which Knabenshue is using in his new airship, built to carry two or more people. The engine is built entirely upon new and original lines and is particularly wonderful because it weighs only fifty-four pounds and generates by actual test from twelve to sixteen horse power. When it is remembered that the actual gas engine of that size weights from three hundred to one thousand pounds the full extent of this creation can be realized. Naturally enough Knabenshue is jealous of his proud achievement and many of the details of its construction he has sanctioned the publication of a few general facts concerning the engine. The engine is of a two cycle pattern, and runs nicely at 100 revolutions a minute. The engine is valveless and starts absolutely without fall with a half turn. It will work will any carburetor. One of the features of the engine is the spark coil, which is also a freak. The coil, instead of containing, as do most coils, two windings of wire, a primary and secondary, contains six windings, the last five of which are looped in series with a battery of condensers. The carburetor throttle and spark timer are also inventions of Knabenshue. The oil lubricator is different from most others in that it sends the lubricant into the machines with the gas mixture. So powerful is the engine that it required a great deal of experimenting to so fasten it in the frame of the ship that it would not tear itself away. This difficulty was finally overcome by supporting it with angle irons, braced and counterbraced, to the wooden frame of the airship, which is reinforced with steel pipe several feet either way from the engine.
