OIL-BURNING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 506,027, dated October 3, 1 893. Application filed July 1,1892- Serial No. 438,667. (No model.)

To all whom it may concern:

Be it known that I, FRED L. BABcocK, a citizen of the United States, residing at Terra Cotta,McHenry county, Illinois, have invented certain new and useful Improvementsin- Oil-Burning Apparatus, of which the following is a specification.

The object of my invention has more particular reference to the burnersin which crude oil or petroleum is used to generate steam in stationary boilers; and my invention consists in the features-and details of construction hereinafter described and claimed.

In the drawings, Figure 1 is a longitudinal vertical section taken through a steam boiler provided with my improved burner in line 1 of Fig. 2, looking in the direction of the arrow; and Fig. 2 is a vertical section taken in line 2 of Fig. 1, lookingin the direction of the arrow.

In making my improved oil burning apparatus, I have preferred to illustrate and describe it in connection with astationary tubular steam boiler, A, which may be incased in brick work, or otherwise located and supported as may be desired. I carry a pipe, B, from a tank or other convenient source of oil supply, and lead it into the fire box or combustion chamber C.

In order to introduce the oil with sufficient force to deliver it in a stream or jet, and also to supply a desired amount of steam for purposes of combustion, I lead a steam pipe D from the steam dome of the boiler or other convenient place, and terminate the end of the steam pipe in the oil pipe B, so that the oil and steam will be commingled and delivered together into the combustion chamber. Theintroduction of the steam causes the oil to be delivered into the combustion chamber in a jet or forcible stream, so that it will be carried fully in and delivered at the desired place, without the use of pumps, or other tions f. At the bottom of the combustion chamber, and leading forward from the perforated wall, I arrange a slab or plate F, made of tire clay or other refractory material, so as to be able to withstand the great heat to which it is exposed in use. At the top of the perforated wall F, and leading forward into the combustion chamber, I arrange another slab or plate F made of similar material, and supported in place in any convenient way. I prefer, however, to arrange a longitudinal partition G extending from the wall F forward as far as the slabs or plates F and F This partition serves to supportthe weight of the slab F and is provided with perforations through it, as is the wall F at the rearof the combustion chamber. It divides the rear end of the combustion chamber into two compartments, communicating with each other through the perforations in the partition G. Immediately behind the wall F is provided a space H, and a number of perforations hlead into this space through the wall F below the fire chamber.

, In operation the oil and steam are introduced into the combustion chamber through the pipe B, where they are lighted, and in which they continue to burn as long as oil and steam are supplied. Air passes up through the grate bars and supplies the requisite quantity of oxygen to maintain combustion. The perforations, f, through the wall at the rear of the combustion chamber, are not large enough to permit all of the heat and products of combustion to pass through, but permit a desired proportion to pass through into the space H. The rest of the heat and products of combustion are forced forward and around the upper slab or plate F when they are able to pass through the space, I, under the boiler. By thus forcing them forward they are brought into contact with the lower side of the boiler near its end, so as to insure an equal heating of the boiler at that point,

as well as at others, and thus maintain an equable temperature throughout. As the'products of combustion pass back, the portionof heat and products of combustion that has passed through the perforations f into the space H join them, and are carried along with them to the end of the boiler, when they are all drawn back through the tubes of the boiler and pass out through the smoke stack J. As this is going on, air will be drawn in through the openings h to mingle with the products of combustion that have passed through the perforated wall, and on up into the channel or space I, so thatif the combustion has not been completed in the combustion chamber, it will be carried on as the heat and products of combustion are carried forward and through the boiler. In this way, and-by this arrangement and mode of operaation, I am able to efiect acomplete combustion of the oil and steam introduced, so as to secure their greatest heat producing capacity for the generation of steam. Of course, it will be understood that I propose to apply my oil burning apparatus to any objects and uses to which it may be applicable, although, as above said, I have preferred to explain it in connection with a stationary steam generating boiler.

What I regard as new, and desire to secure by Letters Patent, is

1. In an oil burning apparatus, the combination of a combustion chamber, means for carrying oil and steam into the chamber, a perforated wall at the rear of the chamber having a space arranged behind it, and means for introducing air into the space from outside the combustion chamber, and a plate extending forward from the top of the perforated wall to force a portion of the products of combustion forward around its front edge, substantially as described.

2. In an oil burning apparatus, the combination of a combustion chamber, grate bars arranged in the bottom of the chamber, means for carrying oil and steam into the chamber, a perforated wall at the rear of the chamber, a plate extending forward from the perforated Wall and resting on the grate bars, and a plate extending forward from the top of the perforated wall to force a portion of the products of combustion forward aroundits front 5 edge, sn bstantially as described.
