THE INDIA RUBBER WORLD 



[September i, 1909. 



Berlin when the valve opened during an ascension. The ques- 

 tion whether the ignition of the gas is to be attributed to the 

 use of metal parts on the valves, still remains unsolved, although 

 there is undoubtedly a possibility that the use of wooden 

 valves would obviate the danger of ignition. The Clouth con- 

 cern has constructed such a valve, in which there is absolutely 

 no metal part. The very numerous endurance and distance con- 

 tests held during the past few years, in which such exceedingly 

 high time records as 72 hours, for instance, were made, have 

 been the means of gathering a good deal of experience in 

 regard to the question of making the most practical use of the 

 limited space in the basket or car. so to make it as com- 

 fortable as possible for the aeronauts. The providing of such 

 comfort is the only means for preserving their physical strength 

 and keeping them in condition for withstanding the severe strain 

 and exertion. The basket or car manufactured by the Clouth 

 concern not only provides comfortable seats, but also a cot on 

 which the aeronauts can lie at full length. Moreover, the 

 basket or car wall required for this arrangement has been so 

 constructed that the strength of the car or basket itself remains 

 practically impaired, and that it appears well able to withstand 

 the shock of landing even under the most imfavorable circuni- 

 .stances.

'Tx all manufacturing lines in which sewing machines arc 

 used, the Singer machines are in the front rank, and this like- 

 wise applies to balloon sewing. The styles used for this purpose, 

 viz. :. flat and post machines with- one or several needles, adapted 

 for sewing simultaneously several parallel lockstitch seams, have 

 proved their efficiency for this kind of work for a number of 

 years past. For sewing widths of fabrics with adhesive surface, 

 these sewing machines are furnished on request with alternating 

 presser foot. The Singer Company Nahmaschinen A.G., of 

 Frankfort-on-Main. are exhibiting several of these machines. 

 In this conneclicn we would express our surprise at the fact that 

 no German sewing machine manufacturer has had sufficient fore- 

 sight to exhibit such machines at this exposition, although Ger- 

 many boasts of a considerable number of sewing machine works 

 manufacturing .'Jnecial machines for all trades." 



INTERNATIONAL AIRSHIP TESTS. 



""PHE historic French city of Rheims was the arena, during 

 ■*■ the last week in August, of the most important series of 

 contests in the history of aeronautics. Forty-four machines — 

 monoplanes and biplanes — were entered for seven different con- 

 tests, by representatives of five nations. Neither of the Wright 

 brothers participated, but five of their biplanes were at Rheims, 

 operated by their pupils or persons who had purchased the ma- 

 chines. The United States were further represented by the 

 Herring-Curtiss biplane. Louis Blcriot. the Frenchman who 

 recently sailed over the English Channel in his monoplane, was 

 an entrant in contest for the valuable coupe internationale d' 

 nviation, scheduled for .August 28. Besides the expensive 

 trophies, cash prizes aggregating 400,000 francs [= $77,200] 

 were offered. According to a recent announcement of the Aero 

 Club of France, all the contestants at the Rheims meeting were 

 entitled at the same time to compete for the Michelin distance 

 prize of 20,000 francs f= $3,860!, which last winter w^as won 

 by Wilbur Wright, an American, in a flight of 76.38 miles. This 

 is a prize to be given annually for eight years to the aviator 

 making the greatest distance during the year. The results were 

 not available in time for publication in this issue. 



AIRSHIP PATENT LITIGATION. 



The latest kidication "f the advent of the aeroplane as a 

 practical invention is indicated by the beginnings of litiga- 

 tion over patents between rival inventors. The Wright brothers 



have tiled a suit in the United States circuit court at Buffalo, 

 New York, against Glen H. Curtiss and the Herring-Cuttiss 

 Aeronautic Co., of Hammondsport, N.Y., alleging infringment 

 of patents. The Wrights have also filed a suit in New York city 

 against the Aeronautic Society. 



"As an answer to their suit," said A. ]\L Herring, president 

 of the Herring-Curtiss company, in a New \''ork Herald inter- 

 view, "we arc doubling the capacity of our works at Hammonds- 

 port, and now have 120 men working day and night on aero- 

 planes alone." 



It is reported that Monsieur Bleriot has obtained a monopoly 

 in iM-ance of the type of motor in his flight over the English 

 channel, and possibly litigation will result. ^I. Bleriot is men- 

 tioned as having made a fortune from patents on automobile 

 attachments before becoming interested in aviation. The rela- 

 tion between aerial navigation and other, forms of transporta- 

 tion is further suggested by the fact that Glenn H. Curtiss at 

 one time made a world's record for motorcycle speed on a ma- 

 chine embodvins a motor of his maiiufacture.
