MACHINE FOR TREATING INNER SOLE FABRICS. 



The machine in the illustration is for softening or rendering 

 adhesive the coated surface of proofed fabric such as is used 

 for making inner soles. Fabric coated with rubber has a ten- 

 dency to curl, and it is, of course, difficult to apply the solvent 

 evenly over the coated surface unless i ; is perfect!) llat. For 

 this reason this device is provided with a movable bed plati 

 and a stationary solution pad of absorbent material. The fabric- 

 is fed between these two members, and the pressure applied 

 the bed plate smooths out the fabric while the solution is uni- 

 formly applied to the coated surface [B. F. Chamberlin, Jr.,

RICHERT'S DIPPING AND DRYING MACHINE. 



This invention provides a machine for making such rubber 

 articles as are produced by repeatedly dipping forms in rub- 

 ber solution and allowing the coating to dry between the suc- 

 e dippings. The two side frames mounted on base plates 

 earings of the driving and dipping shafts and also 



an air circulation. The dipping frame supporting a large num- 

 ber of forms is lowered by lifting belts operated by a hand

MACHINE FOR MAKING RUBBER MOSAIC CARPET. 



Rubber flooring is usually constructed of interlocking tiles of 

 i ions colors and shapes, which are carefully laid and cemented 

 together. Rubber carpet is also made with hand-stamped pat- 

 terns, inlaid with colored rubber shapes of various designs. Now 

 we have a machine that cuts out small cubes or squares from 

 different sheets of white or colored rubber, assembles them 

 together and forms a continuous length of mosaic carpet, which 

 is wound in a roll ready to be vulcanized. 



The rolls of colored stock A are supported by the side frames, 

 and the sheets are simultaneously fed over the revolving cutting 

 drums B. The peripheries of these drums are fitted with ad- 

 justable knives that are arranged to cut the cubes from the 

 sheets as they pass between the drums and the presser rollers C. 

 As the drums revolve, the cut cubes are delivered on a backing 

 cloth D, and are held in alignment by the sharp points of an 

 endless belt of card cloth E, penetrating through the backing 

 cloth. The cubes and cloth then pass between the calender rolls 

 F, and around a heated drum G, which softens the solution on 

 the cloth and causes the cubes to adhere to it. After passing 

 i en the final calender rolls H, where the pattern is con- 

 solidated, and the edge trimming knives /. the mosaic carpet is 



the drive gearing. Extending across the top of the machine wound up on the roller /, and is then vulcanized. [Bertrams,
