for fire extinguishment that has been invented since the steam 

 fire engine was introduced. There have been improvements in 

 engines, ladders, hose, and rolling stock of all kinds, but of new 

 inventions, original in all respects and of practical utility, there 

 have been none for over twenty years." 



Other towers were built for different cities, Boston buying 

 one in 1882 that was destroyed in the great fire of Thanksgiving 

 day, 1889. A few years later Messrs. Ashworth and Petrie, of the 

 Chicago Fire Department, had built in the repair shops a telescop- 

 ing brass tower of similar description, which is in use to-day in 

 the Chicago Department. In 1888 Chief Hale, of the Kansas City 

 Fire Department, invented a water tower that practically replaced

the Greenleaf. The Kansas City Fire Department Supply Com- 

 pany took up the manufacture of the new machine. Two telescop- 

 ing square steel shafts rest on trunnions at the forward end of the 

 truck and a chemical engine takes the place of a hand-screw in 

 raising the tower into position. The inner shaft, lined with hose, 

 is raised by cable and pulleys, drawing after it a length of hose 

 that is already attached to receiving nozzles at the base. The 

 delivery nozzle is under perfect control by the aid of guide ropes- 

 The tower is made in different sizes, varying from thirty to sixty 

 feet in height. 



In 1893 the Fire Extinguisher Manufacturing Company, of 

 Chicago, placed on the market the Champion water tower, that 

 differs essentially from the Hale tower. This was the invention 

 of their superintendent, Mr. E. Steck, who has done much impor- 

 tant work in the way of ladder trucks, chemical engines, and other 

 fire appliances. Hand power replaces the chemical engine in rais-
