CHAPTER IX. 



HYDRAULIC, 



Engine hose. Hydraulic presses. Force pumps. Water wheels. Suction hose. Improved spiral 

 hose. Connecting hose. Hydrant hose. Faucets. Reservoirs. Filters. 



Some articles which come under this head were made, to a 

 limited extent, at an early day. Hose of some kinds was found 

 useful made of native gum. Hydrostatic beds were also made 

 by spreading India rubber cloths over boxes of water, bottles 

 were also among the first articles manufactured to considerable 

 extent by the Roxbury Company. 



ENGINE HOSE. 



This is an article which has been made, to some extent, of 

 coated canvas, but which has yet been found to answer but in- 

 differently, chiefly on account of the gum peeling from the 

 cloth. It is expected that gum-elastic felt, and the fibrous 

 fabrics, will be found to remove the objections that now exist. 

 Engine suction hose, which is made upon wire wound spirally, 

 can unquestionally be made to advantage of these fabrics.
