THE INDIA RUBBER WORLD 



[April i, 1908. 



fabric in the roll and so stretching it that it is turned from 

 straight weave to bias weave; then by coating it with a secret 

 preparation, said to be 20 per cent, rubber and 80 per cent, 

 fineh' divided cotton, and further by doubling the fabric over on 

 itself, in fact making a double texture of it, he produces a won- 

 derfully tough, cheap, bias fabric from which all the stretch has 

 been taken. It will be seen at once that the flimsiest, cheapest 

 cloths thus stretched and built together must form a fabric practi- 

 cally untearable, stronger than a fabric of equal weight made 

 of the best long fabric, and yet infinitely cheaper. It will be 

 further seen that this process is applicable to cotton, silks, in fact 

 to any of the fibers used in cloth making to-daj'. 



The matter is of present interest to the American rubber trade 

 because of the incorporation of the Bias Waterproof Fabric Co., 

 who have offices in New York and who expect soon to have a 

 factory in Passaic, New Jersey, operated by the inventor himself. 



Bias fabrics are not unknown to rubber mill practice to-day. 

 In both the shoe and mechanical goods trades fabrics are cut in 

 bias strips and used where a maximum of strength and a minimum 

 of stretch are sought. The two points of apparent novelty in 

 the invention are the doubling of two bias fabrics together (or 

 greater strength and the secret rubber and cotton solution which 

 is said to be a most important part of the new fabric. To be 

 wholly exact the doubling of two bias fabrics with rubber be- 



Through the courtesy of the treasurer of the company, Mr. M. 

 P. de Bor, The Indi.\ Rubber World is able to present a picture 

 of the machine used in making this bias cloth, and incidentally a 

 likeness of its inventor.

 as a practical designer of rubber machinery, has brought out

tween is, after all, not new. Back somewhere in the seventies 

 Henry G. Tyer, of Andover, Massachusetts, manufactured a 

 goring for the Congress arctics, where the fabric was stretched 

 biaswise by winding it slowly over a wooden shell and wind- 

 ing in on one side curved pasteboard lifts, thus stretching one 

 "jnargin of the sheet of fabric and allowing the other to shrink. 

 This was doubled against another sheet of fabric with rubber be- 

 tween, stretched in the same way, the object being to allow of the 

 production of a strip of double texture cloth that, pulled in one 

 direction, would be quite elastic, the product being just the re- 

 verse of what is sought by M. Voland. 



The American company just formed, which has been incorpo- 

 rated for $300,000, plans to form subsidiary companies to take 

 over the production of fabrics for various lines of manufacture. 

 For example, one company will be formed for the manufacture 

 of balloon cloths, cotton and silk fabrics for the mackintosh 

 trade, and whatever else the rubber clothing trade call for. An- 

 other will take up fabrics for belting, hose, and automobile tires, 

 while still others will cover the general clothing trade and go 

 into the manufacture of light untearable sails, non-leaking um- 

 brella covers, tents, and so on. 



Johnston's Rubber Mill Cr.\ne. 



[Outline view of crane handling a roll from grinding mill.] 



a small crane for use in rubber factories, something that all 

 manufacturers will appreciate. 



Any kind of hoist may be used, hand power, electric or pneu- 

 matic, and which can be operated from the floor, by means of 

 pendant hand chain. This arrangement makes a simple and re- 

 liable method of transferring heavy and light loads of any de- 

 scription at the least cost of install, and at the same time gives 

 an easily worked system of transferring. 



In order to get the most eflicient arrangement to suit any 

 particular requirement, the outlay in general must be done to 

 suit the building, but as this arrangement can be inade to trans- 

 fer the trolleys and hoists in any desired direction, it is of the 



Johnston's Rubber Mill Crane.

Utmost importance to so arrange that the longest runs will be 

 for the transfer-crane itself, and that the individual or single 

 tramrails can be put in to reach almost any corner where it 

 would be impossible for the main transfer-crane to cover. 



In this way a transfer system can be built that will cover 

 not only one or more buildings individually, but that can be alto- 

 gether connected with each other — for instance :
