SANDSTONES FOR RUBBER WORKERS. 



One of the best forms of whetstones for keeping in condition 

 the hand knives nsed in ordinary rubber cutting is the old-

sonu- of the harder sharpening stones do. It also has the merit 

 of being inexpensive enough to permit of extensive factory dis- 

 tribution wherever cutting is done by hand. (Scranton Whet- 

 stone and .Mirasive Wheel Co.. Scranton, Pennsylvania.)

APPARATUS FOR PRODUCING WATERPROOF FELT. 



THE object of this device is to produce waterproof fedt suitable 

 for a substitute for leather in the manufacture of soles, suit- 

 cases, trunks and the like. 



The container A is provided with a specially arranged screen B, 

 between the convolutions 

 of which the rectangular 

 sheets of felt, one quar- 

 ter of an inch thick, are 

 placed. When a vacuum 

 is created in the con- 

 tainer by means of a 

 pump connected to the 

 vacuum tank C, the 

 waterproofing material is 

 admitted to the container 

 from the tank D, and im- 

 pregnates the felt. After 

 a short period the water- 

 proofing material is 

 forced back into the solu- 

 tion tank, the impreg- 

 nated felt sheets are re- 

 moved from the con- 

 tainer, pressed and sub- 

 mitted to a drying 

 process. (Charles T.
