THE INDIA RUBBER WORLD 



429 



PERSONAL MENTION, 



Edward H. Huxley, president of the United States Rubber 

 Export Co., arrived from England on the steamer "St. Paul" on 

 April 14. Mr. Hu.\Iey, it will be remembered, was a passenger 

 on; the "Sussex" when she was destroyed on March 24. His prompt 

 and thorough report of the affair to the United States Govern- 

 ment brought him commendation from newsjiapers all over the 

 country. 



J. P. Krentz, formerly superintendent of the foundry of the 

 Buffalo Foundry & Machine Co., Buffalo, New York, lias been 

 appointed works manacer of the company. 



Eugene Pearl, the many-sided man — artist, attorney and in- 

 inventor, whose corset shield and syringe nozzle patents have 

 been mentioned in The India Rubber World, has just invented 

 an anti-skid shoe sui)port for bootblack stands, the idea being 

 to hold the shoe steady under the manipulations of the polisher. 



Victor von Schlegell was recently elected vice-president of 

 the United & Globe Rubber Manufacturing Cos., Trenton, New 

 Jersey, with headquarters in the Equitable building. New York 

 City. Franklin Edson has been made assistant to Mr. von 

 Schlegell. 



R. L. Chipman, dealer in crude rubber, gutta percha and allied 

 gums, has moved into more commodious quarters at 23-25 Beaver 

 street, New York City. 



The Rev. Dr. W. Warren Giles, of Orange, N. J., who has 

 been a speaker at several dinners of The Rubber Club of Amer- 

 ica, Inc., while running for a train recently, failed to see a train 

 approaching from the opposite direction and was knocked down 

 and severely bruised. His many friends in the rubber trade will 

 be glad to know that he is now as well — and as witty — as ever. 



Albert Waterhouse, president, The Waterhouse Co., Limited, 

 Honolulu and Singapore, was in New York last month on busi- 

 ness pertaining to the various interests managed by his com- 

 pany. He reports that the Pahang and Jahore plantations, 

 through the agency of the Waterhouse company, are progressing 

 under most favorable circumstances. 



W. Stuart Gordon, well known crude rubber man, formerly 

 of Manaos. who recently arrived in New Y'ork from the Far 

 East, sailed for Para April 26. 



Francisco Conde de .A.thayde, a well know-n rubber merchant 

 of Manaos. Brazil, is in New York on a two months' business 

 trip. 



Andrew Kangas, formerly with the commission house of 

 Thomsen & Co., New York City, has become assistant e.xport 

 manager for the Fisk Rubber Co., Chicopee Falls, Massachusetts, 

 assisting John B. Maus. 



W. K. Frederick has been appointed assistant sales manager of 

 the Batavia Rubber Co., Batavia, New York. Mr. Frederick was 

 formerly special jobbing representative in the middle west for the 

 Pennsylvania Rubber Co., and later with the McGraw Tire & 

 Rubber Co. 



The McGraw Tire & Rubber Co. of New York, Inc., with 

 general oflfices and works at East Palestine, Ohio, announces 

 that C. E. Wertman, formerly assistant branch manager, has 

 been promoted to the position of resident manager of the New 

 York office, succeeding R. F. Hobron. and that E. E, Cowan has 

 been appointed sales manager of the New Y'ork territory. 



The Associated Garages of America has changed its name, 

 to represent its varied interests more accurately, to the National 

 Retail Automobile Trade Association. 



TIRE FABRIC TESTS SHOWN BY LANTERN PRO- 

 JECTION. 



'T'HE uide difference of opinion regarding the testing of fab- 

 rics is doubtless due in a large measure to the inaccuracy 

 of the apparatus employed. Great variations are obtained from 

 the same fabric tested on the same dynamometer when held by 

 different means. It is, therefore, obvious that the more data 

 submitted under these varying conditions, the wider the differ- 

 ence of opinion may be. Textile fabrics, owing to their nature 

 and lack of sharp outline, are difficult to reproduce by photo- 

 graphic means. Lantern 

 slides, or motion pic- 

 [ ! tures, when magnified 



and projected upon a 

 screen are too indefinite 

 to illustrate the actual 

 effect of stress upon the 

 fabric. The value of 

 motion photography for 

 this work is greatly 

 lessened by the fact that 

 a film is usually in con- 

 tudy of the sample is im- 



of rubber testing raa- 



At the twentieth annual meeting of the National Fire Pro- 

 tection Association, to be held at Chicago, Illinois, May 9, 10 

 and 11, one subject to be considered and discussed will be 

 "Standard Hose Couplings and Hydrant Fittings for Public Fire 

 Service." 



Slant motion and a more deliberate 

 possible. 



Henry L. Scott & Co., manufacturers 

 chines, conceived the idea of reproducing or projectmg upon a 

 screen by means of an opaque projection lantern a highly magni- 

 fied view of a fabric sample during a test. The apparatus shown, 

 in the cut was therefore constructed and exhibited before Com- 

 mittee D-13 of the American Society for Testing Materials in 

 the office of the United States Rubber Co., New York City, 

 on March 17. 



Parts of a standard horizontal tire fabric tester were mounted 

 upon an oak base A constructed to also support a Balopticon 

 lantern B. No recording head was used. The fixed clamp C 

 was held rigidly in a horizontal position on a solid iron frame 

 attaclied to the base. The moving clamp D was attached to a 

 diaw bar, or stretching screw E, operating through a gear box 

 holding the driving mechanism. Hand wheels F on either side 

 of the gear box were used to transmit power to the stretching 

 screw and were geared to give any speed desired. The hand 

 wheels G at each end of the machine permitted changing clamps 

 quickly. Knurled and adjustment collars, movable upon the 

 thread of the stretching screw, assured the return of the moving 

 clamp to the same position for each sample. 



In addition to the flat grip clamps shown in the drawing, other 

 devices were used and by means of interchangeable anvils or 

 gripping surfaces several methods of testing were illustrated. A 

 device was also arranged for working two knives underneath 

 the sample to cut the fabric in such manner as to produce the 

 "gash" test. 



The api>aratus was installed in a darkened room and the pro- 

 jection made upon a special aluminum screen at a distance of 

 approximately 20 feet. As nearly all tests, were made on tire 

 fabric, having 23 ends per inch, each end thus projected was 

 about 1 inch in diameter. Samples were broken in a bone-dry, 

 normal and saturated condition to note the effect of moisture. 

 Tests showing the effect of varying speeds of the moving clamp 

 were also made. 



Elongation, number of threads broken, effect of tension, slip 

 in the clamps and comparative values of different methods were 

 readily observed. As innumerable tests could be made and any 

 test repeated, the speed regulated, or the stretching motion 

 stopped for any length of time desired, many interesting points 

 were brought out.
