SPECIFICATION forming part of Letters Patent No. 397,784, dated February 12, 1889.

Application filed February 25, 1888. Serial No. 265,282. (No model.)

T0 @ZZ whom it may concern:

Be it known that I, JOSEPH DARBY, of Springfield, in the county of Clark and State ot' Ohio, have invented certain new and useful Improvements in Il vdrocarbon-Burners, of which the following is a specification.

illy invention relates to that class olf burn* ers or retorts in which oil and water or steam .are converted into a vapor or In the accompanying drawings, Figure l is a perspective view of my improved burner in its preferred form; Fig. 2, a top plan view with the capplate removed; Figs. and ll, vertical sectional views taken at, right angles to each other.

A indicates the main retort, which will advisably be formed of a single casting, the said retort having' on its under face a depending nipple, B, threaded externally, and it is provided, further, with a laterally-extending flange, C, as clearly shown in all the figures.

Communicatin with the inlets D and E are the oil and water channels F and G, which are separated from each other by the concentric walls or flanges H and I.

In order to further separate the passages and prevent the mingling of the oil and water, the wall H is connected with the outer wall of the retort A by means of a flange, J, which joins the wall of the retort at a point between the inlets I) and E, as elearlyshown in Fig. 3.

The central curved wall, I, is likewise connected with the outer wall of the retort A by means of a web or flange, II, as shown in Figs. 2 and 3, the web extending inward between the separated ends of the circular wall H. A radial web or flange, L, projects from the inner face of the curved wall H inward between the separated ends of the curved wall I, and serves to conduct the mingled 'oil and water into the central discharge-outlet; M, in the bottom of the retort.

From the foregoing construction it will be noticed that the water and oil are caused to travel back and forth before they are allowed to leave the retort. As these retorts are usually made of cast-iron, it has heretofore been found almost impossible to secure such a smooth surface as would not retard the passage of the oil and canse a deposit of carbon; and to overcome this objection I make the bottom of the channels preferably slightly curved or rounded, and eoat the inner faces of these channels with asbestus retort-lining which fills up all the roughness in the bottoms of the channels and makes a smooth surface.

'lhe curved dividing-walls H and I and the webs J,- K, and L all extend upward to the same height as the out-er wall of t-he retort proper, and to the upper edges of these walls I apply a cap-plate, N, which will be secured to the retort by means of bolts O, which pass through the laterally-projecting flange C of the retort and through ears P, formed upon the cap-plate. However, before placing the cap-plate in position I place on the under side of said plate a disk or sheet, Q, of asbestus, and as the bolts are tightened up the upper edges of the walls are ilirmly embedded linto this asbestus disk Q.

R indicates the lower retort or burner, which is provided with a threaded neck, S, to screw onto the threaded nipple B, the said burner being further provided with jets or openings T upon its upper face, as clearly shown in Figs. I, f3, and a. The lower end of the burner R is closed, and is adapted to fit into a plate, U, which is formed. with a socket to receive and form a support for the burner and retort. l

'Ihe j ets T in the burner are so arranged to direct the .tlame directly against the under face of the main retort A, and, as the oil and water which travel through the circuitous vchannels F and G are highly heated, they are converted into a vapor or gas by the time they reach the central discharge-outlet, M.

I am aware that it is not new to bring the oil and steam into a chamber thro ugh separate IOO oi the flange Il, a central dischargeoutlet, aA web, J, j oinin gf the Wall of the retort with the flange I-I, and inlets D andE on opposite Sides of the web J.

2. In a 'retort having' the circular wall, an inner ring-'like flange, II, having its cndssepara1:.e fi,a ring-like \va1l,I,witl1i11 but separated. from the flange 1I, and having its ends sel'mraied, wehe1 l( and L, extending, respect ively, l'roin the retort-Wall and flange H inw Wardly between the open ends of theri11glike Walls or anges II and I, a central discl'iargeoutlet within the space in closed by the Wall I, awel), J, connecting the Wall olf the retort with the flange I-I to forni passages F and G, 1

inlets D E on opposite Sides of' said web, a cap-plate, and a burner.

JOSEPH DARBY.
