NEW GOODS AND SPEc:iALTlES IN RUBBER. 



" EUREKA " AUTOMATIC MAGNETIC SEPARATOR. 



ONE of the first difficulties the pioneer manufacluitrs . ( 

 reclaimed rubber experienced was that of removutj 

 iron from the reclaimed stock. This iron appeared m 

 the form of nails, metal shanks, rivets, etc. After tl;e 

 wasie stock has been cracked and ground as finely as necest^aiy 

 M cMrrful examination of it will discover many particles of ihis 



--^ metal. Indeed, often there 



are large pieces which le- 

 iiiain in the stock and show 

 on the surface of the calen- 

 dered sheet, many times de- 

 . ^;^ stroying hundreds of dol 

 l.irs' worth of surface goods, 

 and when used for wire cov 

 ering destroying the insu- 

 lating qualities of the rul- 

 ber. Perhaps the best a- - 

 rdngciiieiit fur icmoi u g ir^ 11 ur sieel while the reclaimed rub- 

 ber is ill pr.jcess of manufacture, is the machine shown in the 

 accompanying illustration This machine is very simple, con- 

 sisting of a hopper, into which the ground rubber is fed and 

 through which it flows over a magnetized surface to which the 

 iron at once adheres, while the rubber, not being affected, goes 

 on down to a bin below. Across the surface of this magnetic 

 field runs a leather belt wiper which removes the adhering par- 

 ticles of metal, carrying them away to a waste box on the side. 

 The machine is wholly automatic and will last almost indefin- 

 itely. It requires very little care, cleans itself, and is not costly. 

 The magnetic tract is charged by magnets made specially lor 

 this use, each one tested to lift 20 to 25 pounds. The poles 

 are covered with special iron, giving the strongest charged mag- 

 netic surface possible to obtain. The machines are made in thir- 

 teen sizes, the prices running from $55 to $400 each. These 

 magnetic separators are in use in many of the largest rubber 

 reclaiming factories in the United States and abroad. [The S.

IMPROVEMENT IN FELT BOOTS. 



Charles E. Seibert, of Baltimore, Maryland, has obtained 



a patent for a leather band to surround the ankle of the felt 



boot worn inside an arctic or a rubber boot, to overcome the 



drawback to this style of foot covering which sometimes arises 



felt boot made accoiding to this patent, and the cut on the lelt 

 shows the same upon the foot and inside an arctic. The ank- 

 let band d. of leather, extends entirely around the boot in the 

 position sho.vn. It is sewn to the felt by the rows of stitching 

 <■ and/, but not at the lower edge, which is free to " buckle,' 

 as shown by the shaded portion A. 



NEW "service" HEEL. 

 A FEATURE which is designed to add wearing quality to ilie 

 rubber shoe at a point which it gets the hardest service is the 



new heel, added 

 only to certain of 

 the first qu.iliiy 

 goods manufiic- 

 tured by the Bos- 

 ton Rubber Shic 

 Co. This new fea 

 t jre is termed the 

 'service heel" and 

 IS really an extra 

 quality heel made with a rolled edge tind brought up on the 

 rear as a further protection. This is added to the regular 

 "Storm Slipper," the " Norword " and the "Medium Over' 

 styles. 



THE "LITTLE GIANT" HOUSEHOLD PUMP. 

 The pan) illas'rated herevith scarcely needs special de- 

 scription, aj the cuts tell the whole story. It may be well, 

 however, to refer to soma of its advantages. The cup weighs 5 

 ounces, is made of rubber, with a metal shield which extends 



from the liability ol the kll 10 become damp from perspiration 

 or otherwise, and thus get spongy and break, or quickly wear 

 out at the ankle, where it is continually flexed by the move- 

 ment of walking. There is also a tendency of the felt to abrade 

 the upper edge of the arctic. The cut on the right shows a 



to within one half inch of the bottom of the cup, thus allowing 

 the latter to adjust itself to the opening. It is both a force 

 pump and a lift pump, and has great power either way. It has 

 an extra adjustable rubber washer made to fit pipes from i/ 

 inches to 2 inches. As the barrel of the pump is 7 inches long 

 it gives a plunger stroke of 6}4 inches. The attachments are 

 easily and quickly put on or taken off. The weight of the 

 pump is 16 ounces. It will remove the most obstinate obstruc- 

 tion, whether it be one or 20 feet from the waste outlet. [The
