THE INDIA RUBBER WORLD

incuts, The fimiitcwl Tinu-s asserts, further stating that the 

 position in respect to these is "nothing of a nature to frighten one." 

 Although the British Ihuilop company, as stated in this letter from 

 A. Cuniiingliam, its secretary, is not responsible for the linancing 

 of the .Xmerican undertaking, it is naturally concerned that the 

 good-will of the world-famous name of Dunlop should not be 

 jeopardized, and to that extent the British company cannot afford 

 to be indifferent to the fortunes of its kindred undertaking. 



The directors of the Dunlop Tire & Rubber Corporation of 

 America are: Pierre du Pont, chairman of the E. I. du Pont de 

 \emours Company and of General Motors; Anson W. Burchard, 

 vice-president and director of International (ieneral Electric Com- 

 pany. Schenectady. Xew York ; Robert W. Pomeroy, director of 

 the Manufacturers' and Traders" National Bank. Buffalo, Xew 

 York; J. Westren, managing director of the Dunlop Tire & Rub-

 Sir Harry McGowan, K.B.E., chairman of E.xplosives Trades, 

 Limiteit^- (now. Xobel Industries, Limited), Dunlop Rubber Co.,

Operations at the Buffalo plant being ptactically suspended tlie 

 following statement was made by the company on Jaiuiary 12. 



"The directors have decided that general conditions in the auto- 

 mobile industry are such that they are justified in slowing down 

 their program until conditions improve. April 1 is the probable 

 date of resumption of activities, although it may be inuch sooner 

 if the conditions justify." 



.\pproximately $36,000,000 has been spent by the company since 

 1,'uilding operations were started a year and a half ago. 



It was decided that vanadium should not be used in tlie dye- 

 ing of merchandise for rubberizing. 



It was decided that no restriction be placed upon iron pending 

 a scries of experiments similar to those for chromium. 



It was decided that ether extracts should not show an excess 

 of 2 per cent in the fabrics dyed and finished for rubberizing 

 purposes. 



Dr. Cohocs, chairman, appointed the following committee on 

 specifications; E. Montalent, of H. A. Metz Co., representing dye 

 manufacturers; J. F. 'W'arner, of the Bronx Co., representing 

 finishers; .-Mfred L. Helwitz, of Alfred L. Helwitz & Co., repre- 

 senting converters; Harold D. Mitchell, of the "Vulcan Proofing 

 Co., representing rubberizers. 

 The following were among those present at the conference : 

 John Bancroft, Jr., D. S. Ashbrook, and Dr. "Wallace P.

MEETING 07 RUBBERIZERS AND DYERS OF RAINCOAT FABRICS 



.■\ meeting of a group of rubberizers, cloth converters and dyers 

 interested in the manufacture of raincoats was held in Xew 

 "^'ork City on January 5, 1921. The purpose was to discuss the 

 dyeing and finishing of goods intended for rainproof garments 

 and to arrive at an understanding regarding the eUmination of 

 those dyestuffs and methods of dyeing which result in the dete- 

 rioration of the rubber used in proofing after brief aging. 



Many raincoat manufacturers have sustained serious losses 

 due to the fact that cottons, silks, cotton mixtures and other 

 fabrics bought from the converters frequently contain metal 

 salts injurious to the rubber coating. Fast-colored goods that are 

 not incompatible wMth rubber are required by the raincoat man- 

 ufacturers. This is a chemical problem to be settled by the 

 dyers and dyestuff mainifacturers in cooperation with the rub- 

 berizers. 



The interests of the dyer of cloth are in conflict witli those 

 of the rubberizer and, perhaps for the first time, a concerted 

 effort has been made to discuss the questions involved and arrive 

 at practical recommendations to meet the situation. These 

 recommendations are eml)odicd in the following resolutions 

 adoi)ted by those present under the chairtnanship of Dr. Wallace 

 P. Cohoes, representing Joseph Bancroft & Son. Wilmington, 

 Delaware. 



Copi)cr should not be present in fabrics for rubberizing pur- 

 poses and in the test if any blue color is obtained from a 10-gram 

 sample after incinerating, and is dissolved in nitric acid, and 

 treated with ammonia, the copper might be considered in excess. 



It was decided that chrome can be allowed as an oxide. 



Samples tested by leaching out with water should not show 

 presence of chromates (jr cliromium salts. 



That a committee representing dyestuff' mrumfacturers, dyers, 

 converters, and rubberizers l)e appointed to cooperate and make 

 tlie necessary tests to determine the effect of chromium compound 

 upon rubberizing. 



It was decided that manganese be eliminated. Tests for manga- 

 nese to be as follows : That when a 10-gram sample of cloth is 

 ignited and fu.sed with sodium carbonate, no green coloration 

 should be noted. 



MOTOR AND ACCESSORY MANUFACTURERS' ASSOCIATION 



.\t the annual meeting of the Motor and Accessory Manufac- 

 turers' .Association, held at Hotel Biltmore, New York City, Jan- 

 uary 12, F. C. Glover and H. L. Horning were elected to the 

 board of directors to succeed Christian Girl and E. W. Beach, 

 who have been identified with the Association both as members- 

 and directors for many years. L. M. Wainwright and E. H. 

 Broadwell were reelected as directors, their terms having ex- 

 pired this year. The board of directors now includes, besides 

 these members, C. E. Thompson, \V. O. Rutherford, G. Brewer 

 Griffin. J. M. McComb, G. W. Yeoman, A. W. Copland. C. H. L. 

 I'linterni.in, and E. P. Hammond. The following day the board 

 held a meeting for the election of new officers, naming E. H. 

 Broadwell president to succeed Charles E. Thompson, who has 

 served for two years. Mr. Broadwell until this year served as 

 vice-president of the association. Other oflncers elected were: 

 W. O Rutherford, first vice-president ; A. W. Copland, second 

 vice-president ; H. L. Horning, third vice-president. True to a 

 tradition of the association, L. M. Wainwright was reelected treas- 

 urer, and G. Brewer Griffin was reelected secretary and assistant 

 treasurer. 



The parts and units makers continued last year's departure from 

 precedent by holding a "speechless" banquet and show in the 

 grand ballroom of the Hotel Commodore, January 12, which was 

 attended by approximately 600 men connected with the Asso- 

 ciation. The entire cast of the Ziegfeld Midnight Frolic was 

 transported from the New Amsterdam Roof to the Hotel Com- 

 modore, where the show was presented under automotive auspices, 

 many features being especially arranged to appeal directly to- 

 members of the industrv. 



PNEUMATIC-TIRED TRACTORS 

 Even the steel tires of tractors are giving way to pneumatic 

 tires. Tractors thus tired are giving excellent service in saw- 

 mills for hauling lumber dollys, moving dump wagons, switching 

 railroad cars at docks, and transporting heavy pieces on skids or 

 rollers; general hauling with regular trailers, and in logging 

 camps where they tow loaded trucks to the main roads. It is 

 claimed that a tractor equipped with pneumatic tires can get 

 better traction, has greater mobility, can be handled with re- 

 markable advantage in plowing and cultivating, and that it can 

 travel faster in pulling a load on rough or even ground.
