THE INDIA RUBBER WORLD 



[September i, 1904. 



RUBBER FACTORY APPLIANCES. 



TWO ENGLISH SOLUTION STRAINERS. 



THE illustrations presented on this page relate to certain 

 devices used in the manufacture of waterproof goods in 

 Great Britain, which will appear novel to many of our Amer- 

 ican readers. 



In the first place are shown two views of a solution strainer 

 of the screw type, which is a very strong and efficient machine

for its purpose. It consists of a truly bored castiron cylinder 

 about 16 inches in diameter and 18 inches deep, with a remov- 

 able finely perforated bottom, mounted on strong standards of 

 sufficient height to admit a can or tank beneath the cylinder. 

 Over this perforated plate, fine removable copper gauze discs 

 are fitted. After the cylinder has been charged, pressure is 

 brought to bear upon it by a well fitting plunger, fitted upon 

 the end of a powerful screw brought down by means of the 

 worm and worm wheel, countershaft, and belt pulley arrange- 



ment. The machine is fitted with very strong crosshead, pillars, 

 guide for screw worm and worm wheel, shaft, fast and loose 

 pulley, and automatic belt shifting arrangement, all so arranged 

 that when the plunger has reached the bottom, undue strain 

 will not be brought to bear on the bottom plate. An arrange- 

 ment by which the plunger is quickly lifted by means of hand 

 wheel is provided, ready for cleaning and recharging. 



The succeeding views relate to a simple solution strainer 

 This consists of a single roller fixed in the bottom of a wood 

 hopper, against which adjustable slides, fitted with leather 

 strips, press. The rollers are mounted on strong castiron 

 standards, and driven by a belt pulley, suitable arrangements 

 being made to prevent the oil used for lubrication of the bear- 

 ings from getting inside the hopper. The machine is suffi- 

 ciently high to admit of a good sized tin being placed under- 

 neath the roll, and drip guides (not shown in the illustrations) 

 are supplied with the machine. [David Bridge & Co., Castleton

THE PRICE OF RUBBER SHARES. 



FROM " THE NEW YORK TIMES, AUGUST 14. 



To the Editor of The New York Times : Will you please inform 

 me through the columns of The Times why United States Rubber stocks 

 are selling at 19J4 for the common and at 74 to 75 for the preferred, 

 while United States Leather common sells at l\ and the preferred at 

 83 ? Is not the Leather stock as good as the Rubber ? Why the dif- 

 ference in price ? J. C. w. 



New York, Aug. 9, 1904. 



APART from other considerations affecting the relative 

 values of the common and preferred stocks of the United 

 States Rubber Co. and those of the United States Leather Co., 

 a satisfactory explanation of the much lower price quoted for 

 Leather common lies in the fact that there are back dividends 

 due on the company's preferred stock to the extent of about 40 

 per cent., whereas the preferred stock of the United States 

 Rubber Co. is noncumulative, so that the suspension of divi- 

 dends on Rubber preferred, which lasted from 1901 to this 

 year, when dividends were resumed, did not result in a fixed 

 charge on the company's earnings. No dividend can be paid 

 on Leather common until the 40 per cent overdue dividends 

 have been paid on the preferred stock of the company, whereas 

 a dividend on Rubber common could be declared at any time 

 after provision had been made for the annual dividend of 8 per 

 cent, on the preferred. 



NOT PLEASED WITH CONSUL CONLEY. 



TO the Editor of The India Rubber World: I am 

 very much delighted with the position of your magazine 

 with reference to rubber culture in Mexico. It seems to me 

 that the legitimate rubber companies ought to combine and re- 

 quest of President Roosevelt that he appoint some one to take 

 the place of Consul Conley. 



Again thanking you for the interest you are taking in this 

 great enterprise, I am, Very sincerely yours,

SIMPLE SOLUTION STRAINER. 



The American Rubber Co. filed incorporation papers at Santa 

 F6, New Mexico, on June 16, with $200,000 capital named. 

 The headquarters are at Tucumcari, Quay county, N. M. The 

 object is to extract rubber from shrubs which are reported to 

 exist in New Mexico, as well as in Colorado and Utah.
