Delano^s Improved Method of Burning Coal. 

 M. J. Frisbie, agent, 248 Pearl_street, N. Y. 



The leading pecu- 

 liarity of Delano's 

 method of burning 

 coal , as illustrated 

 by a stove on exhibi- 

 tion, and l3y drawing 

 accompanying this 

 ■description, is in the 

 mode by which the 

 coal is supplied to 

 the fire, which is 

 from beneath, against 

 the fire, through the 

 hottom of the grate. 

 The mode by whick 

 this is effected, is as 

 follows : Attached to 

 the grate is a feeding 

 box, round or square, 

 with a movable bot- 

 tom, which, when 

 raised to the top of 

 tlie box, is on a level 

 with the upper sur- 

 face of the grate. 

 When it becomes ne- 

 cessary to add more 

 fuel, the box is filled, 

 and is carried, by a 

 swivel, directly under 

 the fire, the grate 

 sliding b^ck as the 

 box advances. When 

 the box is directly 

 under the fire, the 

 ignited coal rests up- 

 on the fresh coal in 

 it. The bottom of the 

 box is then thrown 

 up by means of a 

 lever, and the charge 

 carried directly into 

 the stove, or fire 

 chamber; the bottom 

 of the feeding-box, in its turn, serves as~a grate, till it is drawn forward again, 

 followed by the grate proper, on the same level. When the grate is again in its 

 place, the bottom of the feed-box falls, and the box is again m readiness for ano- 

 ther charge. 



The first thing gained by this mode of feeding, is the combustion of the gaseous
