THE INDIA RUBBER WORLD 



[February, 1, I9l2. 



A NEW HOSE MOLD. 



A NEW SECTIONAL RUBBER SQUEEZE ROLL. 



A MOLD for curing hose in lengths up to five hundred feet 

 at a single operation has been recently designed and per- 

 fected by the Adamson Machine Company, of Akron, Ohio. 



The new mold, which is the invention of a mold e.:pert, has 

 become the subject of considerable interest, especially among 



T.\" machines used for washing wool, rubber-covered rolls are 

 used to squeeze the water from the cleansed material. These 

 rolls are subjected to heavv pressure, and being turned constantly 

 in one direction, the rubber has a tendency to crawl, and separate 

 from the center or shaft, thus becoming practically useless for 

 the work the rolls are intended to perform. There are other 

 mechanical operations in which similar rolls are used, perhaps 

 the most generally known being clothes-wringers for laundry 

 or family use. 



To overcome this difficulty on the part of the rubber cover, a 

 metal sleeve is made with a series of longitudinal grooves, wider 

 at the bottom, than the top, and in section quite similar to car- 

 penters' dovetails. These grooves are slightly tapering from one

rubber manufacturers of the east, and many orders are in conse- 

 quence being received ; in fact, these molds have been installed 

 by many of the biggest and busiest 

 plants interested in mold work, and 

 are regarded as standard in their 

 line. 



In addition to mold work the 

 Adamson company are extensive 

 manufacturers of many types of 

 rubber-making machinery and de- 

 vices, and its newly erected and 

 equipped foundry and machine 

 shop constitutes perhaps, size con- 

 sidered, one of the best appointed 

 machine plants in the west, and 

 the fact that it is generally taxed 

 to its full capacity indicates the 

 active request for Adamson pro- 

 ducts. 



Mr. Alexander Adamson, the 

 founder of this business, is one of 

 the best-known machinists in the West and is one of Akron's 

 most highly respected and progressive citizens, and he is gen-

end to the other, and fitting into them are sections of rubber, so 

 made that when so fitted they form a cylindrical roll similar in 

 shape to the ordinary rubber covered metal roll. These sections 

 of rubber are tapered, so that they may be arranged alternately 

 with their wider ends at opposite ends of the roll, and proper 

 mech.'uiical means are proxided to hold them in place. This 



arrangement prevents 

 the pressure of an op- 

 posing roll from acting 

 upon the whole length 

 of the joints, and obvi- 

 ates any tendency of the 

 joints to open. In a 

 roll thus constructed any 

 one of the rubber strips 

 or sections may be re- 

 moved and another in- 

 serted without disturbing 

 the others. 



A modification of the 

 dovetail arrangement of 

 Cross Sectional View. fastening the rubber 



strips is the use of triangular or cylindrical bars, which fit 

 in grooves in these rubber sections, these bars being adjusted and 

 held in place by nuts by which the strips are compressed, so 

 that the joints. are .firmly closed. It is obvious that such rolls 

 are far more economical than the old-fashioned solid ones, be- 

 cause, in case of injury or undue wear, only a section needs re- 

 placement instead of an entire new roll being required. This 

 roll is the invention of Ira F. Burnham, president of the Stough- 

 ton Rubber Co., Stoughton, Mass.

erally regarded in the trade as an expert in all matters pertain- 

 ing to mold work. In this capacity he is called to rubber mills 

 throughout the country. 



The new plant, which was recently completed, was constructed 

 with the sole idea of meeting the requirements of the various 

 lines of mechanical work to which it is devoted, and the labor 

 employed is of the most skilled and best class of mechanics to 

 be obtained in that section. 



ANOTHER NEW USE FOR RUBBER. 



A prominent feature of the Whiteley dry goods palace recently 

 opened in London, is the liberal use of glass for show cases 

 and counters ; wooden ones of the old-fashioned type being as 

 far as possible avoided. In the lower part of these glass counters 

 there is inserted an adjustible foot rest covered with rubber, 

 which is intended to protect the counters from the feet of shop- 

 pers. 



Tlic B. F. Goodrich Co., of Akron, Ohio, has declared a 20 

 per cent, dividend on its $10,000,000 common stock, payable in 

 preferred stock. This will increase the preferred stock to 

 $6,000,000 cutstandiiig.
