THE RUBBER TRADE AT TRENTON 



BY A RESIDENT CORRESPONDENT. 



THE Home Rubber Co. report an increase in business for the 

 first three months of this year of 25 per cent, over the 

 same period of last year, and that all departments are affected 

 by the increase. The installation of an automobile tire wrap- 

 ping machine will give them an increase in the output of that 

 department, and establish another milestone in their growth in 

 tire manufacturing. 



The Empire Rubber Manufacturing Co. will soon occupy 

 their new plant, 60 x go feet, which will be used exclusively for 

 the manufacture of tires. They have recently opened branches 

 in Kansas City and Indianapolis. They report that their "Non- 

 nerbestos" steam hose, which is of asbestos and rubber construc- 

 tion, patented some time ago, has met with much favor. 



The Acme Rubber Manufacturing Co. report business thus 

 far this year far in excess of any previous year in their his- 

 tory. They state that the present high price of raw rubber has 

 not yet manifested itself in the number and size of orders re- 

 ceived. All departments are busy, and they have contracts for 

 all the tires they will produce this season. 



The Thermoid Rubber Co. report excellent trade conditions. 

 They have opened an office in Philadelphia, with Messrs. Spencer 

 & Dando as their representatives, for the sale of their automobile 

 goods. They are installing a general electric power equipment 

 with the idea eventually of operating the plant electrically 

 throughout. They have made recently some conveyor belts of 



unusual dimensions, up to 50 inches wide, 8 plies, and weighing 

 abi iut 7,000 pounds. 



The Essex Rubber Co., manufacturers of specialties for the 

 mechanical and other branches of the rubber trade — and par- 

 ticularly for the shoe manufacturing trade — report a busy season. 

 Their fiscal year just closed shows twice the volume of business 

 of last year. They have added lately to their premises a tine 

 three-story brick and steel building, in which is installed a com- 

 plete machine shop, at the disposal of such of the company's 

 customers as may require special molds or dies. Both the 

 domestic and export business of the company are responding to 

 the increased business of the country. Mr. C. H. Oakley, presi- 

 dent and general manager of the company, has had an unusually 

 wide experience in the rubber manufacture. 



The United and Globe Rubber Manufacturing Cos. feel de- 

 cidedly optimistic, and report sufficient contracts to carry them 

 far into the future. 



The Whitehead Brothers Rubber Manufacturing Co. report 

 very satisfactory conditions from the selling standpoint. They 

 state the present prices of rubber have not in any way curtailed 

 the demand for their goods. 



The Joseph Stokes Rubber Co. are understood to have all 

 the business they can handle, in both hard rubber and cotton 

 hose departments. 



The Mercer Rubber Co. have opened an office in Pittsburg, 

 indicating that they are widening the scope of their operations 

 in the pursuit of trade. 



The Luzerne Rubber Co. have outgrown their existing premises. 

 The addition to their plant announced in the February issue 

 of The India Rubber World is being completed as rapidly as 

 possible. One of the features of the improvement of their 

 plant will be a machine shop, with an equipment that will make 

 them independent in so far as machine work and repairs are 

 concerned. 



The Vulcanized Rubber Co. have all the business that they 

 can take care of conveniently, but report that a continuance of 

 the high prices of rubber is stimulating interest in celluloid and 

 other insulating materials. 



The Hamilton Rubber Manufacturing Co., through their agent, 

 Mr. W. L. Blodgett. say that they are well satisfied with the 

 present volume of business. 



John E. Thropps Sons Co. have been compelled to add largely 

 to their equipment, to satisfy the demands made on them for 

 molds for the rubber trade. They report working night and 

 day, and are behind with orders. 



General C. Edward Murray, treasurer of the Empire Rubber 

 Manufacturing Co., returned recently from a brief vacation in 

 Florida. 



Mr. W. H. Sayen, Jr., treasurer of the Mercer Rubber Co., 

 was married on March 31 to Miss Edith Conyers, daughter of 

 Mrs. James Adams Conyers, at Hamilton, Bermuda. His brother, 

 Frederick Sayen. secretary of the company, was best man. The 

 bridegroom was vice-president of the class of IQ05 at Princeton 

 University, and the chairman of the class memorial fund. He is 

 an enthusiastic cricketer, and it was while abroad with a cricket 

 team that he met Miss Conyers in Bermuda. 



The Raymond Rubber Co., manufacturers of reclaimed rubber, 

 report that they have a satisfactory share of business. 



L. Albert & Son, dealers in waste rubber, report scarcity in 

 some stocks. Shoes are now coining in in large quantities, 

 which can also be said of carriage and automobile tires. It is 

 hinted that stocks are being withheld from the market by the 

 smaller gatherers awaiting high prices. 



There were 21,000 Hevea rubber plants iif;the nurseries of the 

 British Guiana botanic gardens at the beginning of this year, 

 ready for distribution during February. The price asked was 

 $3-75 P er I0 °. or $35 P er thousand — the estimated cost of produc- 

 tion. Besides, 30,000 seeds had been ordered.
