(From a Sketch Made by Mr. Gillespe.)

No one knew better than Mr. Gillespie, however, that they were but part way solutions, not at all successes as yet. Over months previous he had been working on other phases of the problem. Possible triumph after more months of work is within his grasp. A third Gillespie Aeroplane is projected, which, because of new development, in the field of motors and the establishment of certain other very interesting principles, may perhaps, start a new chapter in this most unsolvable science up to date.

Mr Gillespie's new idea and special applications of them to air navigation are just now ready to be talked about. They have been held in secret thus far. Gillespie himself is the most entertaining of men. He resides in Prospect Park West, at the corner of Ninth street, and spends his summers abroad his yacht

Who Has Some Remarkable Plans for Construction of a New Form of Airship



Gaviota, in Gravesend Bay, Off the Brooklyn Yacht Club house. He is, besides being an expert inventive mechanic, an expert photographer. His wife is probably the most accomplished Brooklyn yachtswoman to-day, and a woman of very magnetic personality.

Naturally there is much about his new airship that Mr. Gillespie will not discuss. It is not built yet, though it is well within the process of making, and the crucial factors of all, the motors, that in airship work are revolutionary and theoretically of great promise, are practically determined upon. But the final setup, the assembling, the combining of the special features in just such a way, Mr. Gillespie wants to accomplish himself first. There are too many [?men?] on the prowl for airship ideas [?]plications, and an inventor a[?]selines, this yachtsman thinks, [?cannot?] be too secretive.

For this same reason it was difficult to get him to draw the sketch that accompanies this article. The sketch was made, none the less, and gradually the inventor was persuaded to talk about his new experiments, which probably are the most interesting developments at the moment in the history of aeronautics.

If Gillespie finally does make a substantial advance in human flying it will in a great measure be due to what he has worked out in motors. Practically, the position up to date has been that motors that would fill the bill for stability have weighted down each airship pension this is 4.71 pounds per horsepower.

"The machine entire will weigh (framework and motive power) 402 pounds. Add 120 pounds for the operator, 522 in all. The actual [?lift?] of 35-horsepower is, however, 700 pounds, which leaves a surplus of 178 pounds, or opportunity to carry something like 22 more gallons of gasoline, which mean that with 26 gallons of gasoline altogether the machine can travel for six and half hours.

"The calculated speed is sixty miles an hour. An aeroplane must move like an arrow to keep in the air. This can stand suspended. To test this I shall assemble the machine in a great room. In the test it must support itself, suspended, and all the gasoline it can carry.

"Furthermore, I will say that the structure will comprise of two forward propellers and six horizontal propellers. It will be 38 feet 6 inches long and 12 feet wide, and taken apart, can be stored away in two small packing cases. The cost of these machines I estimate at $7,500 to $8,000. In the case of war twenty of them could. I am certain, be assembled in a few moments on the deck of a battleship".
