In the development of the device com- [ ] mercial features have been given as much consideration as have engineering features. As a result of this consideration the stoker is well within the reach of the middle class buyer as regards price, while at the same time it possesses all of the features of comfort, economy and convenience which accompanies this type of stoker. The stoker is of the over feed type and uses the natural draft of the furnace.
