WATER AND OIL VAPORIZER AND BURNER.

SPECIFICATION forming part of Letters Patent No. 392,510, dated November 6, 1888. Application filed January 13, 1887. Serial No. 224,307. (No model.)

To all whom it may concern:

Be it known that I, EDWIN D. GRANGER, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, haveiuvented certain new and useful Improvements in Water and Oil Vaporizers and Burners, of which the following is a specification, reference being had therein to the accompanying drawings.

Myinvention relates to certain new and useful improvements in stoves and heating devices which employ oil and water as fuel. Said oil and water being vaporized in a heated retort forms a combustible vapor which when lighted will generate a large amount of heat, the object of my invention being to provide acheap, simple, and effective means for generating, igniting, and burning vapor, so that it may be employed for heating purposes; and my invention consists in the special construction, combination, and arrangement of the parts, as will be'hereinafter fully set forth, and specifically pointed out in the claim.

In the accompanying drawings,which illustrate my invention, Figure l is a side View, partly in section, of an oil and water vapor izer, burner, and heater constructed in accordance with my improvement. Fig. 2 is a detail perspective view of the burner detached, and Fig. 3 is a view, partly in section, showing my improvement as applied in use.

A refers to the outer casing, which is preferably oval in form, the lower portion being tubular, as shown at a, to which portion is suitably connected a base, Z),which is mounted on legs. The outer casing, A, may be provided near its lower end with a suitable door or open ing, through which access can be had to the burner when desired, and between the base I) and the outer casing, A, may be located a damper, c. The outer or exterior casing is made up of two or more parts which are bolted to each other, and near the upper portion is located an eseapepipc, d, which leads, preferably, into a heating-drum, D, of ordinary construction, which is connected by suitable pipes to'a fine or chimney.

The base I) may be of any suitable construction or configuration, and-it is preferably provided with a drawer, I), having registers, as shown.

B refers to the interior casing or vaporizer which corresponds in shape with the exterior casing, to which it is attached by suitable bolts, 6 e. The lower or contracted portion of the vaporizer is screw-threaded both internally and externally, the internal screw-threads engaging with the threaded pipe 0, which extends to near. the top of the vaporizer, and this pipe, which is maintained in a vertical position, is provided at a slight distance above the lower end of the vaporizer with a perforation, f, for the purpose, as will be hereinafter described.

The burner D consists of a box or casing which has a perforated top and central opening therein, having screw-threads for attach ing the same to the generator 13. The bottom of this burner-is provided with two or more.

small openings, g g, and beneath the sameis supported by means of bars h, a pan, D 1n which is placed a quantity of asbestus or other absorbent material which is not destructible by iire.

At the top of the vaporizer B, preferabl immediately above the pipe G, the same i provided with an opening or valveseat whic is closed by a suitable safety-valve, F.

At a suitable distance and a convenien point to the heating-tubes is placed a tank which is separated into two compartments, these compartments being for the reception of oil and water, and to the bottom of this tank is attached, by suitable couplings, pipes E and E, these pipes passing through the outer casing and into the vaporizer, where they terminate near the bottom thereof, and these pipes E and E are each provided with cocks z and i, for cutting off or regulating the flow of liquid from the tanks to the vaporizer.

WVhen it is desired to start the fire, the valve leading to the oil-tank is turned, so as to admit a small quantity of oil to the vaporizer, which will escape through the small hole near the lower end of the pipe 0 and finds its way from thence into the burner, from which a small quantity will escape to the pan D and will be absorbed by the asbestuswick. When the oil absorbed by the wick is lighted, it will heat the burner and convert all the oil that may be contained therein into vapor. After the oil which has flowed into the burner i:

consumed, which can be ascertained by the color of the flame, whiclnwhen the oil begins to vaporize, changes from a heavy red to a light blue, the water-valve is then turned, so as to admit water to the vaporizer in about the proportions of two of water to one of oil, and will be fed to the vaporizer, which is heated, said heat converting the same rapidly into vapor, which rises and isforced out of the pipe Ointo the burner, which is in a highly-heated contion, and is burned as it escapes through the perforations in the top of the burner. The heavy particles which are carried by the vapors will escape through the small perforations in the bottom of the burner and collect in the bottom of the pan. By regulating the supply of oil and water the heat can be regulated.

By constructing the parts as hereinbefore described, especially the vaporizer, and having the point thereof downward, larger heatsurfaee is thrown in contact with the flame, and, as the shell of the vaporizer is quite thin, it will be quick to correspond to the heat.

In case the oil and water should be vaporized too rapidly, or an excessive pressure should be cast on the vaporizer, the valve will elevated so as to relieve said pressure.

This device is applicable to heating and cook stoves, and also for furnaces for generating a steam, &c., and when desirable the exterior casing, A, may be dispensed with, as when the same is employed for cooking-stoves.

What I claim, and desire to secure by Letters Patent, is-

In a device for vaporizing oil and water and burning its vapor, the combination of a vapor izer consisting of an inverted conical shell, to the lower end or apex of which a burner is secured, a central pipe connected to said apex of the conical shell at its lower end, and extending upwardly therein to near the top thereof, and provided with an opening, f, near its lower end, the outer inclosing-shell, A, conforming to the shape of the inner shell or vaporizer, the heating-drum connected to and supported upon the top portion of the outer shell, the heater secured to the lower part of said shell, the oil and water tanks, and the feed-pipes E and E, for feeding oil and water from the oil and water tanks to the inner or vaporizing shell, the said pipes terminating near the lower inner portion of the said vaporizing shell or chamber, substantially as described.

In testimony whereof I affix my signaturein presence of two witnesses.
