 A. H. Reid, of Philadelphia, was the first American manu- 

 facturer who introduced the Fjord pattern heater with the ele- 

 vating device. Fig. 38. On 

 Dec. 14, 1899, he applied for 

 patent on an improved heat- 

 er (granted July 3, 1900), 

 where he introduces the 

 steam tangentially through 

 an unobstructed opening in 

 the side of the casing, and 

 where it travels free in the 

 spaces between ribs or rings 

 which are fixed on the heat- 

 ing vessel as shown in Fig. 

 39, which explains itself. 

 They differ from the Danish 

 ring by the upbending of
