MAGNETIC RECLAIMING SEPARATORS. 



OXE of the difficult problems in rubber reclaiming is to 

 eliminate all iron. Overshoes contain it in the form of nails, 

 buckles, stiffcners; tires in the form of lacks, nails, and bits of 

 wire that have been picked up on the road, and so on. For chem- 

 ical as well as mechanical reasons, every particle of this iron must 

 be eliminated, in order to make the reclaimed material of any 

 value. ' 



In the process of reclaiming, the scrap is passed between rolls, 

 which usually leaves the metal flattened into thin pieces. These 

 were formerly removed by hand magnets in a laborious and im- 

 perfect way. Later machines were employed, but the problem 

 has not been an easy one to solve, as most of the available 

 machines were originally designed for treating heavy metals or 

 finely crushed mineral ores, and such separators were not 

 adapted for treating light, bulky rubber stock. 



At the suggestion of an old time inventor and rubber expert 

 the Dings Electro-Magnetic Separator Co. (Milwaukee), have 

 built a magnetic separator for rubber work alone. This sep- 

 arator has proved to be a complete success. Its capacity is large. 

 efficiency perfect, and docs not occupy excessive floor space. 



Type "C" M.^gnetic Separ.\tor. 



[Made by Dings Electro-Magnetic Separator Co.] 



The cut shows a view of Type "C" separator, fully assembled, 

 with the exceptions of a few parts. In operation, the material to 

 be separated is fed from a Dings Universal Feeding Hopper, upon 

 a wide inclined endless rubber belt traveling in an upward direc- 

 tion. Under this belt is placed a large magnetically energized 

 surface, so that the material as it rolls and tumbles down tlie in- 

 cline for a long distance is thoroughly subjected to magnetic in- 

 fluence, making it impossible for any particle of iron to escape. 

 The iron is attracted and held firmly against the belt, and is thus 

 carried upward and over the top of the pulley, when it is re- 

 leased and dropped into a box conveniently supported by brackets 

 on the rear posts of the machine. The iron is released and dis- 

 charged automatically without the aid of brushes, scrapers or 

 cut outs, by reason of its gradual withdrawal from the magnetic 

 field as it reaches the brow of the top pulley. The rubber, being 

 nonmagnetic, falls from the belt to the final delivery at the bot- 

 tom of the incline where it can be either shoveled, spouted, or 

 conveyed away. 



This separator can be ordered in any desired size from 20 to 

 60 inches in width of belt. The machine can be operated on any 

 voltage that may be specified. The power required for the 



mechanical drive is insignificant, being only !4 HP. to 1 HP., ac- 

 cording to size. The electric power required for the magnetic 

 energy varies from ^< to 2 kilowats. according to size. The 

 separator can be provided with tight and loose pulleys for belt 

 drive, or with direct connected motor. 



A CONVENIENT TIRE VULCANIZER. 



THE "Xational" Steam Vulcanizer is constructed of a brass 

 shell partially filled with water. When heat is applied, the 

 \\-titer is formed into steam, thus making it on the same principle 

 of the large steam vulcanizcrs used in tire factories. The steam 

 eliminates the danger of burning the rubber. The heat is sup- 

 plied by an alcohol lamp, with adjustable burner, which makes it 

 possible to use the "National" in the country or anywhere. This 

 vulcanizer has two vulcanizing surfaces, each Sj^ x 5 inches, 

 and is adapted tor repairing both tubes and casings. Cuts in

casings can be repaired without removing them from the wheel. 

 It requires about seven minutes to get up steam, and fifteen 

 minutes to vulcanize. A thermometer gives the exact tempera- 

 ture at all times. The burner on the lamp is so arranged that 

 it can be set so as to maintain a steady even heat for any length 

 of time. The brass shell with water prevents the heat from 

 fluctuating, and distributes the temperature evenly to all parts of 

 the machine. Tlie vulcanizer, with complete outfit of supplies, 

 weighs less than four pounds, and can be carried in the tool box.
