The milk enters the tinned copper vessel B by the funnel- 

 shaped cover C and is forced through a pipe (not shown). 



Shortly after .this, or about the same time, P. J. Buaas 

 (Denmark) constructed the heater "Triumph" in 1895, shown 

 in Fig. 28. A tinned copper cylinder is closed tight by a 

 cover in one end by using rubber packing and the patent fast- 

 eners g. On this cover is a sort of funnel a through which 

 the milk enters the cylinder and is thrown on the heating sur- 

 face in a thin film and at the same time moved forward by 

 the fast revolving screw wing, and elevated through the stand 

 pipe b, nearly 8 feet if so desired. The milk left in the drum 

 is drawn by c. The steam enters the jacket, which is well in- 

 sulated at d, and the condensed water leaves at e. A safety 

 valve is placed at f. 



A similar heater, under the same name "TRIUMPH," 

 made by The Sharpies Company, Chicago and Westchester, Pa., 

 is illustrated in Fig. 29, showing the open end of the hopper

and the cylinder head and propeller removed. A protecting 

 plate prevents the steam from heating the place of entrance 

 too much, both direct and exhaust steam may be used. I 

 understand Mr. S. is contemplating constructing a revolving 

 inner drum w T ith a spiral propeller soldered on the outside in- 

 stead of the present one.
