COMBINED OIL AND WATER VAPORIZER AND BURNER.

SPECIFICATION forming part of Letters Patent No. 433,870, dated August 5, 1890.

- Application filed December 6, 1889. Serial No. 332,802. (No model.)

To aZZ whom, it may concern:

Be it known that I, FRANK B. MEYERS, of Fort Plain, in the county of Montgomery and State of New York, have invented a new and Improved Combined Oil and lVater Vaporizer and Burner, of which the following is a full, clear, and exact description.

ed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures Figurel is a side elevation'of the improvement as applied to an upright boiler,

parts being in section. Fig. 2 is an enlarged sectional side elevation of the burner proper on the line 00 0c of Fig. 3, and Fig. 3 is a sectional plan View of the same on the line y y of Fig. 2.

The improved hydrocarbon-burner is pro vided with a burner proper A, having a base B, on which is secured the upwardly-extending cylinder 0, filled with mineral wool D or other suitable material. The cylinder 0 is inclosed in a shell E, rounded on top and placed with its end on the base B, so as to form above the cylinder 0 a dome F and on the outside of the cylinder 0 a chamber or channel G, which communicates by apertures E in the lower end of the said shell E with a second channel H, formed by an exterior shell I, held concentric with the cylinder 0 and the shell E, and of a similar shape to the said shell E. 7

On the lower end of the outer shell I are formed annular flanges 1, secured by bolts or other suitable means to the base B. The channel H leads at its upper end, on top of the shell E, into a short pipe'P, from the upper end of which extends the annular flange I slightly curved downward, as is plainly shown in Fig. 2. This annular flange I forms part of the nozzle J, which is also provided with an inverted concaved or dished disk J, supported by stays J from a slightlydished disk K, held between the annular flange I and the disk J, as is plainly shown,

in Fig. 2. This disk J and the annular flange '1 are somewhat larger in diameter than the generated by the burner, and as hereinafter more fully described.

The supply-pipe L extends through the short pipe 1 The top of the shell E passes through the mineral wool in the cylinder 0 and then passes through the base B and is provided with a Valve L and a second valve L and then leads into an oil-supply tank N, suspended a suitable distance above the burner proper A, so that the oil flows bygravity and under a certain pressure into the burner proper A-that is, onto the top of the disk K.

From the pipe L above the valve L extends a pipe O,'provided with a valve 0 and connecting with an oil-pump P of any approved construction, and connected by a pipe 0 with a large reservoir Q, containing oil, which is pumped into the tank N to keep the latter supplied with the necessary oil. A pipe L also leads from the pipe L into the reservoir Q, and is provided with a valve L which When opened permits of withdrawing all the oil from the pipe L and the tank N in case the burner is not used for some time.

Into the bottom of the cylinder C leads a water-supply pipe R, passing through the base B and provided near its outer end with a valve R, and leading to the water-supply tank S, which contains water having a constant level to correspond with the top of the cylinder 0, so that when the valve R is opened water flows from the tank S through the pipe E into and through the mineral wool D in the cylinder C to the top of the latter.

In order to keep the water in the tank S at the same level, a supply-pipe T- leadsinto the said tank S and is connected with a watersupply tank U, placed a suitable distance above the tank S, preferably on the same shelf or bracket with the oil-supply tank N, as shown in Fig.--1. The pipe T is provided at its upper end with a valve T and with a regulating-valve T near its lower end, the valve-stem of the lower valve T being connected by an arm T with a float T floating in the water in the tank S and serving to automatically open and close the valve T so as to admit waterinto the tank S to keep the water in the latter at a constantlevel.

On the base Bis secured an annular upwardly-extending rim 13, forming a receptacle for the exterior shell I and for the reoeption of the mineral wool or other suitable material 13 for a purpose hereinafter more fully specified.

The burner proper A, when applied to a boiler V, as shown in Fig. 1, is set in the middie of the fire-box V on top of the grate-bars V which latter support loose fire-brick WV, preferably arranged in the manner shown in Fig. 1, soas to form a cone-shaped bottom in the fire-box V. Below the grate-bars V is arranged the usual ash-pit V through which passes the oil-supply pipe L and the watersupply pipe R to the outside of the boiler, and through the said ash-pit V passes air to supply the fire-box V, the said air mixing with the burning gas generated by the burner A. It is understood that this air from the outside passes through the grate-bars V and the loose fire-brick W before it enters the cone-shaped bottom of the fire-box V. The operation is as follows: In starting, the valves 0 and L are closed and the valves L and L in the pipe L are opened, and the valves R and T in the pipes R and T, respectively, are also opened, so that Waterflows from the tank S through the pipe R into the water-cylinder C, saturating the mineral wool ,D Contained in the water-cylinder C. The oil from the supply-tank N flows through the pipe L into the nozzle J, passes over the disk K down onto the annular flange I and from the latter flows over the outer shell I into the mineral wool B held on the base B, thus saturating the said mineral wool. The operator then ignites the oil on the mineral wool B so that the burner proper A is heated, whereby steam is generated from the water in the mineral wool D, which steam passes upward into the dome F, then downward through the channel G and through the openings E into the channel H, up the latter into the pipe I and through the latter against the under side of the disk K, to be deflected onto the annular flange 1 where it mixes with the oil'dripping down the disk K, so that the mixture flows from the nozzle J at the opening J 3 and is ignited by the burning oil on the base B. The burning gases, after leaving the nozzle J, pass downward in the fire-box V of the boiler V, to be deflected upward by the coneshaped bottom, made of fire-brick W, in the said fire-box, so as to heat the boiler in the usual manner to generate steam fromthe water. "It will be seen that by this device no,

separate'fire is necessary in the fire-box V in order to start the apparatus, as the burning oil in the mineral wool b on the base B -heats the burner proper A to generate steam from the water, so that the said steam, after passing through the channels G and H, mixes with the oil in the nozzle J, so that a mixture of oiland steam passes out of the nozzle and burns on the outside of the burner A to heat the boiler.

By the use of the mineral wool in the water-cylinder O the water is prevented from boiling over the upper end of the cylinder C, also preventing the steam from puffing out into the dome F, as the steam passes in a steady stream from the mineral wool into the dome F, and from the latter passes through the channels G and II into the nozzle J. It will further be seen that as the outer shell I is kept hot by the burning gases the steam passing up the channel H is superheated before it reaches the nozzle J. The amount of water passing to the burner properAis regulated by the valve R, and the amount of oil discharged into the nozzle J is regulated by the valves L and L The float T in the tank S to insure a constant level of the water in the said tank, and consequently of the water in the cylinder 0, is filled to about its upper edge constantly with water, so that a constant supply of steam is generated.

when the burner is in operation, the oil passing through the supply-pipe L is readily transformed into vapors by the steam surrounding the upper part of the pipe L in the dome F and pipe 1 so that the steam readily mixes with the said vapors in the nozzle J, thus insuring complete combustion of the gases after they leave the nozzle and are burning in the fire-box. It is further understood that in starting the device oil or other inflamtmable substance may be placed in the outer part of the base B and burned to heat the shells I and E and the cylinder 0 togenerate steam for starting. It will also be seen that the hydrocarbon-burner is always ready for use, and is quickly set in operation to generate its own steam to be mixed with the oil, the mixture being burned in the fire-box of the apparatus to which it is applied.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a combined vaporizerand burner, the combination, with the inner or water cylinder, of the intermediate and outer shells surrounding the inner or water cylinder and forming concentric steam-channels, the outer shell terminating in a nozzle into which discharge the said channels, and an oil-supply pipe located in said nozzle, substantially as described.
