It cannot be styled an Evaporator or Generator, as it burns the oil as simply and completely as a handfull of wood shavings would be burned, if ignited in the fire pot of an ordinary cook stove. To successfully accomplish this result, there are two important and vital features of the stove, and in which ours differs from other styles of “Wickless,” namely: the burner cup that receives and distributes the oil to the flame, and the combustion chamber or chimney where the gases are mixed with air in proper proportion, to produce a blue flame. (See cut No. 1.)
No. 2.
The burner cup of the “Standard” Wickless, as shown in cut No. 2, is made with an enlarged entrance, the channel of the cup being divided so that the oil enters on both sides of the cup, where it is conducted into two channels, upper and lower, entirely around the cup. In this manner the oil is distributed evenly to all parts of the burner, giving a more even and perfect flame than can be secured where there is only a single small entrance to the cup. Further, our cup is less sensitive to being out of level, on account of the manner in which the oil is distributed.
The enlarged opening at the entrance of the cup, provides for the expansion of gas, which always takes place where the oil enters a heated cup, thereby overcoming the tendency toward a pulsating flame which is a common and objectionable feature of all other “Wickless” burner cups, constructed without an enlarged opening at the entrance. By referring to Cut No. 3, it will be seen that the channel cup is constructed with a ledge, which projects from the outer rim toward the center of the cup, on this ledge the outside perforate of the chimney rests. This ledge prevents, to a great degree, the oil from passing by capillary attraction, over the surfaces of the burner, to that part which is outside of the chimney. For that reason the “Standard” Wickless can be operated with less smoke and odor than any other “Wickless” Blue Flame Oil Stove.
No. 3.
The burner cup is made of sheet metal, (brass) which is quickly heated, so that in starting the stove, it can be put in operating in much less time than is possible, where a heavy cast cup is used.
That the burner cup is durable, is proven by the fact that in three years experience with the sheet brass cup, we have never known of one burning out.
The chimney, or combustion chamber of the “Standard” Wickless is a very important feature, and one that is distinctly our own. To secure the greatest efficiency from the burner, it is necessary that the flame be applied as near to the center of the cooking vessel as possible.
