MACHINE FOR MAKING ASBESTOS SHEET PACKING. 



THAT the manufacture of Klingerit packing has progressed 

 in England since the war is shown by the following illus- 

 trations of a novel machine specially designed for making 

 high pressure packing. The mechanical operation is in general 

 the same as the German mill, illustrated and described in the 

 article on the manufacture of Klingerit steam packing that ap- 



peared m The 1ndi.\ Rubber World, March 1, 1917. Tliere are, 

 however, special features in this new machine that are of suffi- 

 cient interest to warrant a brief description. 



A front and side view is shown in the first illustration, the 

 small roll being adjusted to the large roll by worm and pinion 

 gearing operated by two hand disks. Both rolls are chambered 

 for heating and cooling purposes and are revolved by worm 

 wheel and pinion gearing driven by belt power. The machine 

 is started and stopped by independent levers, one being located 



at the front and the other at the back of the machine, that 

 control a friction clutch mounted on the pinion shaft. 



The prepared dough is fed to the rolls in sufficient quantity 

 to build up a thin sheet on the large roll. A solution of rub- 

 ber and balata is then applied and another sheet is built up on 

 the first one in the same manner and solutioned. When the 

 packing has been built up to the desired thickness, the machine 

 is stopped and the sheet is cut transversely by the hand-oper- 

 ated cutting device attached to the side frames at the- back of 



the machine and shown in the second illustration. Just above 

 the transverse cutting device are located the cutting rollers 

 that trim the edges of the sheet. 



The upper end of the cut sheet is then passed over the top 

 roller of the winding frame, shown in the second illustration, 

 and wound up on the lower or windup roller that is belt driven 

 from the upper roller. This roller is driven from a counter- 

 shaft that is attached to the opposite side of the machine and 

 is driven from the front roll. The rolls are of chilled cast 

 iron, the small roll measuring 18 by 41 inches and the large 

 roll 51^4 by 41 inches. Compressed asbestos sheets in vary- 

 ing widths up to 40 inches and 161 inches long may be made 

 on this machine. [Hampson Bros., Limited, Manchester, Eng-

KOSTEEN PACKLESS SWING JOINT. 



The manufacturers of rubber goods are so well aware of the 

 difficulties experienced with leakage in packed joints and hbse 

 connections that the following description of a new type of 



fle.xible joint 

 is of inter- 

 est. Being 

 made en- 

 t i r e 1 y of 

 metal it re- 

 sists high 

 pressure 

 steam, the 

 action of 

 volatile oils 

 and the con- 

 stant effort 



of air to escape at the joints. Moreover, it is said to be unaffect- 

 ed by heat and cold, having been tested with steam at 3S0 degrees 

 F., alternating with cold water at 64 degrees F. The construc- 

 tion will be readily understood by referring to the illustration in 

 which .-; is a hollow cylinder having a ball-shaped shoulder B 

 that revolves on an anti-friction metal bearing ring C. kept in 

 close contact by a spring D, also by the pressure of steam 

 or liquid passing through the joint. The cylinder A is kept in 

 alinement by revolving in a socket E. F is the body and H its 

 cap. These enclose all the other parts. 



The spring D. is made of a cast metal which is not affected 

 by changes of temperature and is guaranteed to keep a con- 

 stant pressure during the life of the joint. 



For vulcanizing presses, two styles are recommended, the 

 Flexible and the Standard; two of the former and one of the 

 latter are usually sufficient for a connection between two platens. 

 These joints are used in connection with ordinary iron pipe 

 on elbows and carry the guarantee of the manufacturer.

DINGS MAGNETIC SEPARATOR. 



The reclaiming of rubber scrap for reuse includes various 

 processes among which that of metal separation by means of 

 magnets is of importance. Such equipment is used to 

 prevent damage to crushing and grinding machinery due to 

 "tramp" iron frequently found in rubber scrap. Magnetic pul- 

 leys are recommended where large quantities of coarse material 

 are to be handled and the iron to be extracted is limited in 

 quantity. 



In operation the material is fed upon a horizontally inclined 

 belt conveyor passing over a magnetized pulley. The non- 

 magnetic material falls by gravity from the brow of the pulley
